Product Description

The Z-shaped mixer model WH is designed and manufactured by our company based on the development of advanced foreign technologies, taking into account the actual production conditions in various sectors of domestic industry. In recent years, the equipment has been widely used, especially in the amino plastics industry. The machine integrates the functions of mixing, shearing, dewatering and reaction. The agitators and dynamic seals have undergone numerous modifications and tests. The equipment is characterized by large loading weight, low energy consumption, low leakage, convenient and fast unloading, long uptime and ease of maintenance, and has received wide recognition from customers.

Design of a Z-shaped mixer and its operating principle

⑴ Structure of Z-shape mixer: ① The body, which is mainly composed of a cylinder (jacket and reinforcement structure), and left and right side plates. ② The frame which mainly supports the body, motor, gearbox, drive system and hydraulic cylinder tilting system. ③ The drive system, which mainly consists of electric motor, reducer, clutch, differential gear, oil seal, stirring shaft, bearing housings, wear-resistant steel bearing bushings, bronze bushings and hydraulic cylinder tilting system. ④ Electrical control system, which mainly consists of electrical control cabinet and piping. (Refer to the electrical connection diagram and control principle for details.)

⑵ Working principle of Z-shaped mixer: Mixing is the main link of the amino plastic production process, and combines mixing, impregnation, shearing (fibre pulp), plasticization and dewatering. It has a significant impact on product yield and quality. This equipment includes targeted improvements to the design of the blades, sealing structure, heating and dehumidification systems. First of all, the body is equipped with a jacket; Depending on the required mixing process temperature, steam or hot water can be supplied for heating. Between the inner stainless steel lining and the outer jacket, reinforcing posts and reinforcing ribs are provided, so that the inner lining can withstand the pressure of heating steam and the large compressive force that occurs during direct rotation and shear of wood pulp during mixing, without cracking or collapsing, and does not affect the circulation and drainage of water when heated. The two blade shafts are mounted symmetrically with opposite directions of rotation and operate at different speeds. Forward rotation promotes shearing and impregnation, reverse rotation promotes dewatering and loosening of the material. During operation, the material moves completely in the axial direction, radial direction and between the two blades, without dead zones. Mixing is uniform, the material is loose and breathable. The drive uses a two-speed electric motor: when loading, slow mixing is used, and when mixing, fast mixing is used. The gearbox with hardened teeth has small dimensions, low noise level and high transmitted torque. It is more durable than conventional gearboxes. Unloading is carried out by hydraulically tilting the cylinder, unloading is fast, uniform and loose.

Technological Process of Z Shape Mixer

Amino plastic production line

Amino resins include three main categories: urea-formaldehyde electrical powder (UF/A1), melamine powder (MF/A5) and tableware finishing powder. Complete production lines are equipped with the entire technological cycle: resin synthesis → dosing and mixing → drying → crushing and grinding → sifting and dust removal → packaging of finished products. Standardized series with a capacity of 10/20/30 tons per day are offered, as well as individual non-standard design for an annual capacity of 3000–10000 tons.
