Description

Technical Field

[0001] This utility model relates to the field of modified plastic granule production technology, and in particular to a cooling water tank for an extruder. Background Technology

[0002] An extruder is an important piece of plastic machinery, and most plastic products can be produced and manufactured through extrusion molding. The cooling water tank is the cooling device for the extruder. Traditionally, the extruded strip of material is directly placed into the cooling water tank, where the water flow directly impacts and cools the material.

[0003] The above-mentioned existing technical solutions have the following defects: the strip material coming out of the extruder is directly impacted by water, which can easily cause the strip material to break, resulting in a high product defect rate. Utility Model Content

[0004] The purpose of this invention is to provide a cooling water tank for an extruder to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A cooling water tank for an extruder includes an extruder, a cooling water tank, a first water pump, a second water pump, a filter plate, and a water tank. The cooling water tank is located on the left side of the extruder, and the water tank is located on the rear side of the cooling water tank. The first water pump is located at the bottom end of the cooling water tank, and the second water pump is located at the rear side of the cooling water tank. A water inlet is provided at the bottom right end of the cooling water tank. The filter plate is located at the bottom right end of the cooling water tank and at the top of the water inlet. The filter plate is fixedly connected to the bottom end of the cooling water tank. The filter plate has multiple small holes for dispersing the pressure of the incoming water.

[0007] By adopting the above technical solution, the strip material produced by the extruder enters the cooling water tank. Water enters the cooling water tank through the water inlet and impacts the filter plate at the bottom of the cooling water tank, filtering the water and changing the water flow from one stream to multiple streams entering the cooling water tank. This reduces the impact force of the water flow, making the strip material less prone to breakage and improving the product qualification rate.

[0008] In a further embodiment, a water outlet is provided at the bottom left end of the cooling water tank. The water outlet of the cooling water tank is connected to the water inlet of the first water pump through a first pipe, and the water outlet of the first water pump is connected to the water inlet of the cooling water tank through a second pipe.

[0009] In a further embodiment, a water exchange hole is provided at the left end of the cooling water tank near the water tank side, and the water exchange hole of the cooling water tank is connected to the outlet of the second water pump through a third pipe. A water outlet is provided on the left side of the water tank, and the water outlet of the water tank is connected to the inlet of the second water pump through a fourth pipe.

[0010] In a further embodiment, a drain hole is provided on the left side of the cooling water tank.

[0011] In a further embodiment, a fixed bracket is provided below the cooling water tank. The fixed bracket includes multiple support columns, which are axially and evenly distributed at the bottom end of the cooling water tank. The fixed bracket is fixedly connected to the bottom end of the cooling water tank.

[0012] In a further embodiment, a support platform is provided below the second water pump, and the bottom end face of the second water pump is fixedly connected to the top end face of the support platform.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. The porous design of the filter plate effectively filters impurities in the water and reduces the impact of water flow.

[0015] 2. The water tank and second water pump can be used to add and replace the water in the cooling water tank;

[0016] 3. The drainage holes in the cooling water tank can effectively drain the wastewater from the tank. Attached Figure Description
