Problems solved by technology

[0004] 1. The water pressure sent into the water inlet is unstable, and a water vortex is formed during the backflow, which is not conducive to the smooth passage of the material strip through the water tank; in severe cases, the water flow will directly spray out from the water inlet to break the material strip
[0005] 2. Impurities adhere to and disperse in the sink, which is not conducive to cleaning
[0006] 3. A large amount of impurities generated in the production block the water outlet, and the water in the tank is easy to overflow due to the continuous water inflow into the water inlet
[0007] 4. There is a lot of dust on the water surface, which can easily cause product appearance pollution
[0008] According to the patent search, there is only a technical solution to change the material of the cooling water tank from metal to plastic, but no technical solution to change the structure of the above defects has been found.

Abstract

The invention relates to plastic production equipment, in particular to a self-cleaning water tank of a plastic extruder. The cooling water tank of the existing plastic extruder has the following defects that: the water feeding pressure is not stable; the impurities can not be cleaned conveniently; the product appearance can be easily polluted; and the water in the tank can easily overflow. In the technical scheme of the invention, a water feeding pipe (4) and a water discharging pipe (7) are respectively on the lower parts of both ends of a water tank (8); and a flat plate (9) and a meshed plate (10) are arranged on the water feeding pipe (4). A filter screen cover (11) is arranged on the water discharging pipe (7), and a meshed plate (12) is arranged on the filter screen cover (11). The upper part of the side face of the water tank (8) is provided with an overflow hole (6), an overflow water tank (1) is arranged below the overflow hole (6); an impurity collecting plate (13) is arranged in the overflow tank, and a sponge (14) is arranged on the impurity collecting plate (13). The invention has the advantages that: the water feeding flow is stable, the impurities in the water tank can be easily cleaned, the cleanness of cooling water can be maintained, and the water in the tank can not overflow into the environment.

Description

technical field [0001] The invention belongs to plastic production equipment, in particular to a plastic extruder self-cleaning water tank for self-cleaning the strips extruded by the plastic extruder. Background technique [0002] In the production of modified plastics, the strips extruded from the high-temperature melting of the extruder can only be fed into the pelletizer for pelletizing after cooling down and hardening, and then can be processed in the next step. The freshly extruded strips need to be cooled by a water tank filled with cooling water to achieve a hardening effect. Products with high value and high quality requirements also have high requirements on appearance, and external pollution directly affects the pass rate of products. The cooling water tank used in the production of the prior art is a tank whose overall shape is similar to a cuboid. One end of the water tank is located directly below the head of the extruder, and the width of the water tank is sl...
