Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a screw conveyor used for processing recycled rubber. Background Art

[0002] Recycled rubber processing refers to the process of turning discarded rubber products into usable rubber materials through a series of treatments and processing.

[0003] The main steps in recycled rubber processing include:

[0004] 1. Collect waste rubber products: including waste tires, waste rubber hoses, waste rubber sheets, etc.

[0005] 2. Sorting and cleaning: The collected waste rubber products are sorted to remove impurities and pollutants, and then cleaned.

[0006] 3. Crushing and breaking: crush and break the cleaned waste rubber products into small particles.

[0007] 4. Refining and processing: The crushed rubber particles are refined and processed, and the performance and characteristics of the rubber are adjusted by adding appropriate amounts of additives and auxiliaries.

[0008] 5. Production of recycled rubber products: The processed recycled rubber materials are molded and processed to make recycled rubber products, such as recycled rubber tires, recycled rubber tubes, etc.

[0009] The advantages of recycled rubber processing include: reducing the pollution of waste rubber products to the environment, saving resources and reducing production costs.

[0010] It can be seen that the small granular raw materials after the waste rubber products are crushed and broken need to be stably transported to the set process position. In order to meet the transportation requirements, a conical cylindrical hopper is usually used in existing industrial production to transport them. Since the hopper will continuously transport the raw materials, the corresponding operation process cannot accurately obtain the raw materials, and its applicability is relatively poor. Summary of the invention

[0011] The utility model aims to solve the above problems in the prior art and to provide a screw conveyor for recycled rubber processing which can stably control the output and has a compact structure.

[0012] The purpose of the utility model can be achieved through the following technical solutions:

[0013] A screw conveyor for recycled rubber processing comprises a frame, characterized in that it also comprises a conveying box, a driving member, a conveying screw and a discharge pipe, the interior of the conveying box is a cavity and the upper part is open, the bottom of the conveying box is fixedly connected to the frame and the conveying box is inclined, the conveying screw is axially fixed in the conveying box and the conveying screw can rotate circumferentially, the conveying screw is parallel to the bottom of the conveying box, the driving member is fixedly connected in the conveying box and the driving member is connected to the conveying screw, the bottom of the box body at the highest point of the conveying box has a through discharge port, the discharge pipe is fixedly connected to the bottom of the conveying box and the discharge pipe is communicated with the discharge port.

[0014] The screw conveyor for recycled rubber processing creatively sets the conveying box at an angle, so that an inclined conveying channel is formed between the bottom of the conveying box and the side of the conveying box.

[0015] The conveying channel is provided with a conveying screw rod which is arranged parallel to the bottom of the conveying box, and the recycled rubber raw materials are conveyed into the lower end of the conveying box.

[0016] As the driving member drives the conveying screw to rotate continuously, the regenerated rubber raw materials at the bottom of the conveying box are driven by the conveying screw, so that the regenerated rubber raw materials at the bottom of the conveying box can stably enter the upper part of the conveying box. When the regenerated rubber raw materials enter the discharge port, the regenerated rubber raw materials are transported to the set operation process through the discharge pipe.

[0017] The conveying screw includes a rod-shaped body and conveying teeth spirally distributed on the outside of the body. Since the conveying screw is a prior art, the structural and technical features of the conveying screw are no longer described in detail in the specification.

[0018] In the above-mentioned screw conveyor for recycled rubber processing, the inclination angle of the conveying screw is 20-40 degrees.

[0019] This inclination angle enables the recycled rubber raw materials at the lower end of the conveying box to smoothly enter the upper end of the conveying box.

[0020] In the above-mentioned screw conveyor for recycled rubber processing, the number of the conveying screws is at least two, the two conveying screws are arranged in parallel and each conveying screw has a corresponding driving member.

[0021] Multiple conveying screws can effectively improve the conveying stability of recycled rubber raw materials.

[0022] In the above-mentioned screw conveyor for recycled rubber processing, the lowest open end of the conveying box has a hopper, the size of the upper end of the hopper is larger than the size of the lower end of the hopper, the lower end of the hopper matches the upper part of the conveying box and is fixedly connected to the upper port of the conveying box.

[0023] Since the upper end of the hopper is relatively large, and the lower end of the hopper is stably connected with the upper part of the conveying box, the recycled rubber raw materials can be smoothly delivered into the conveying box through the hopper.

[0024] In the above-mentioned screw conveyor for recycled rubber processing, the lower end of the conveying screw is axially fixed to the lower end of the conveying box, and the conveying screw can rotate circumferentially relative to the conveying box.

[0025] The lower end of the conveying box provides sufficient space for the lower end of the conveying screw to be connected.

[0026] In the above-mentioned screw conveyor for recycled rubber processing, a connection seat is provided in the conveying box near the upper end of the conveying box, and the upper end of the above-mentioned conveying screw is axially fixedly connected to the connection seat and the conveying screw can rotate circumferentially.

[0027] The connector has two functions:

[0028] First, it provides enough space for the upper end of the conveying screw to connect;

[0029] Second, it is used to block the recycled rubber raw materials and prevent them from entering the upper part of the conveying box. Because there is a motor at the upper part of the conveying box, it is used to prevent the motor from being affected by the recycled rubber raw materials during operation, such as hindering the heat dissipation of the motor.

[0030] In the above-mentioned screw conveyor for recycled rubber processing, the discharge pipe is located at the lower part of the conveying screw and is adjacent to the connecting seat.

[0031] Since the discharge pipe is adjacent to the connecting seat, such a structure effectively increases the moving stroke of the recycled rubber raw material, ensuring that the conveyor can transport a large amount of recycled rubber raw materials.

[0032] In the above-mentioned screw conveyor for recycled rubber processing, a gearbox is also fixedly connected to the conveying box, the upper end of the conveying screw is connected to the output end of the gearbox, the motor is fixedly connected to the upper part of the conveying box and the rotating shaft of the motor is connected to the input end of the gearbox.

[0033] The power output by the motor is converted into a suitable set speed through the gearbox, and then the conveying screw is driven to rotate continuously at the above set speed.

[0034] In the above-mentioned screw conveyor for recycled rubber processing, the discharge pipe is in a rectangular flat shape, and the width of the discharge pipe matches the width of the conveying box.

[0035] Such a structure enables the recycled rubber raw materials at the upper part of the conveying box to smoothly enter the discharge pipe.

[0036] In the above-mentioned screw conveyor for recycled rubber processing, the width dimension of the discharge pipe is 4-7 times the thickness dimension of the discharge pipe.

[0037] Such a structure can effectively improve the transportation efficiency of recycled rubber raw materials.

[0038] Compared with the prior art, the screw conveyor for recycled rubber processing has an inclined conveying box, and the conveying screw in the conveying box is also inclined, and the inclined direction and angle of the conveying screw are the same as the inclined direction and angle of the conveying box.

[0039] When the conveying screw continues to rotate, the recycled rubber raw materials at the bottom of the conveying box can be stably driven to the upper part of the conveying box, and then the recycled rubber raw materials are stably transported to the set process through the discharge pipe at the upper part of the conveying box.

[0040] It can be seen that due to the large internal capacity of the conveying box in the entire conveyor, a large amount of recycled rubber raw materials can be transported. Its operating efficiency is not only relatively high, but also automatic transportation can be achieved by placing the recycled rubber raw materials into the hopper. It has a high degree of automation and high stability.

[0041] The driving parts and the gearbox are both located in the conveying box, and its structure is relatively compact, with high practical value.

[0042] In addition, since the driving member can control whether the conveying screw rotates, the conveying screw can rotate a set number of times to achieve the conveying of a set amount of raw materials, and its conveying accuracy is relatively high. BRIEF DESCRIPTION OF THE DRAWINGS
