Description

Technical Field

[0001] The utility model belongs to the technical field of baking tanks, and relates to a plastic particle homogenization baking tank. Background Technique

[0002] In the production of existing modified polypropylene plastics, the material strips extruded by an extruder are cooled by the cooling water in a water tank, dried by a blower drying device, and finally cut into pellets by a pelletizer. After passing through a vibrating screen, the qualified plastic particles are directly fed into a homogenization tank. After the material homogenization is completed, it is directly packed and packaged.

[0003] A plastic particle homogenization baking tank is a device dedicated to the treatment of plastic particles, mainly used in the homogenization and drying processes of plastic particles. The plastic particle homogenization baking tank adopts the working principle of spiral stirring to ensure that the input materials are evenly distributed inside the barrel through the main shaft and fall cyclically in a scattering manner to achieve full mixing of the materials. It is applicable to industrial applications such as dyeing granulation, modification of plastic particles, and recycling and processing of recycled crushed materials.

[0004] The existing homogenization device has a relatively simple structure and function. It is mainly divided into two feeding methods: direct infusion at the top of the baking tank and spiral blades. At the same time, the existing spiral stirring causes the plastic particles to fall relatively fast in a scattering manner, and it is easy to pile up together. Therefore, it is necessary to repeatedly dry the plastic particles, resulting in low work efficiency. Content of the Utility Model

[0005] The purpose of the utility model is to provide a plastic particle homogenization baking tank for the above problems.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

Three sets of sieve plates are sleeved on the outer wall of the first feeding device. The top end of the sieve plate is connected to a driving mechanism in a transmission manner. A number of drying fans are installed on both inner walls of the tank body. Second feeding devices are placed on both sides of the tank body. The second feeding device is composed of a blower, a conveying pipeline, and a feeding funnel. The air outlet of the blower is connected to the conveying pipeline in a through manner.

The motor is fixedly installed on the outer wall of the tank body, and the driving end of the motor passes through the tank body and is fixedly connected to the eccentric wheel.

[0013] In the above-mentioned plastic particle homogenization baking tank, one side of the eccentric wheel is movably connected to the connecting rod through a pin shaft. The other end of the connecting rod is movably connected to the support rod through a pin shaft. The other end of the support rod is slidably placed in the sleeve, and the bottom of the sleeve is fixedly connected to the inner wall of the tank body. A spring is sleeved on the sleeve.

[0014] In the above-mentioned plastic particle homogenization baking tank, the three groups of sieve plates are all of a hollow metal plate structure. The central position of the sieve plate is sleeved on the outer wall of the sleeve and is slidably connected, and mounting holes are provided on both sides of the sieve plate.

[0015] In the above-mentioned plastic particle homogenization baking tank, the support rod is connected by a threaded rod. The three groups of sieve plates are slidably connected by sleeving on the support rod through the mounting holes, and support nuts are screwed and connected on both the upper and lower sides of the mounting holes.

[0016] In the above-mentioned plastic particle homogenization baking tank, the drying fans are correspondingly installed on the inner wall of the tank body and are arranged between the three groups of sieve plates.
