Description

Technical Field

[0001] This utility model relates to the technical field of plastic granule production equipment, specifically a stirring device for plastic granule production. Background Technology

[0002] As a basic raw material for polymer material processing, the production quality of plastic granules directly affects the mechanical properties, appearance, and stability of downstream products. During the production of plastic granules, various raw materials need to be thoroughly mixed to ensure the quality of the granules.

[0003] Based on the above, the inventors have discovered the following problem: the current mixing devices used in plastic pellet production do not have a three-dimensional mixing function, resulting in low mixing efficiency and affecting production efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a mixing device for plastic pellet production, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide a stirring device for plastic pellet production, so as to solve the problem mentioned in the background art that the current stirring devices for plastic pellet production do not have a three-dimensional stirring and mixing function, resulting in low mixing efficiency and affecting production efficiency.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A mixing device for producing plastic granules includes a mixing tank. A guide hopper is connected to the bottom of the mixing tank, and a conveying pipe is connected to the bottom of the guide hopper. A feed hopper is installed at one bottom side of the conveying pipe, and a feed inlet is provided at the bottom side of the conveying pipe near the feed hopper. Support plates are installed on three sides of the mixing tank, and support columns are installed at the bottom of the support plates. A mixing mechanism is provided inside the mixing tank, including a mixing shaft. The top end of the mixing shaft is rotatably connected to the top end of the mixing tank's interior, and the bottom end of the mixing shaft is rotatably connected to the bottom end of the conveying pipe's interior. Spiral blades are fitted onto the outer side of the mixing shaft, and the outer side of the spiral blades contacts the inner wall of the conveying pipe. An extension tube is fitted onto the outer side of the spiral blades, and the bottom end of the extension tube is fixedly connected to the bottom inner side of the guide hopper.

[0008] Furthermore, a motor is installed at the top of the mixing tank, and the output end of the motor is connected to the top of the mixing shaft.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the motor at the top of the mixing tank provides power to the mixing shaft, driving the spiral blades and other components to work continuously, thereby automating the mixing and conveying of plastic granules and improving production efficiency.

[0010] Furthermore, a plurality of first dispersing rods are installed at the outer top end of the extension tube, and a plurality of second dispersing rods are installed at the outer middle part of the extension tube. One end of the first dispersing rod and one end of the second dispersing rod are respectively fixedly connected to the inner wall of the mixing tank.

[0011] The beneficial effect of adopting the above-mentioned further solution is that by connecting the first and second dispersing rods on the outside of the extension tube to the inner wall of the mixing tank, the plastic particles in the mixing tank are dispersed, breaking up material agglomeration, while enhancing the installation stability of the extension tube and ensuring its stability when moving synchronously with the mixing shaft.

[0012] Furthermore, the first and second dispersion rods are staggered.

[0013] The beneficial effect of adopting the above-mentioned further scheme is that by alternating the first and second dispersing rods, the contact area and collision opportunities with the plastic particles are increased, thereby further improving the material dispersion effect, making the mixing more uniform, and avoiding insufficient mixing of local materials.

[0014] Furthermore, the outer bottom end of the extension tube is provided with a plurality of return holes, which are distributed at equal intervals.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, through the return hole at the bottom of the outer side of the extension tube, some plastic granules can flow back from the extension tube to the guide bucket, thereby realizing the circulation and stirring of materials, extending the stirring time, and ensuring that the plastic granules are mixed evenly.

[0016] Furthermore, a discharge pipe is installed at the bottom of one side of the guide bucket, and a discharge valve is installed at one end of the discharge pipe.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the discharge pipe and discharge valve on one side of the guide hopper facilitate the control of the discharge of plastic granules after mixing, achieve precise control of the discharge, and facilitate the connection of subsequent production processes.

[0018] Furthermore, a support base is installed at the bottom end of the support column, and the bottom end of the support base is provided with anti-slip texture.

[0019] The beneficial effects of adopting the above-mentioned further solution are that the support base at the bottom of the support column increases the contact area with the ground, thereby improving the overall stability of the device. The anti-slip texture at the bottom of the support base increases friction, preventing the device from sliding during operation and ensuring the smooth progress of the stirring process.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This mixing device for plastic granule production provides space for mixing plastic granules through a mixing tank. The input of plastic granules is achieved through the cooperation of a conveying pipe, a feeding hopper, and a feeding port. The mixing tank is supported by a support plate and support columns to ensure the stability of the device. The stirring shaft of the stirring mechanism drives the spiral blades to rotate, conveying and initially mixing the plastic granules in the conveying pipe. The contact between the spiral blades and the inner wall of the conveying pipe can scrape off residual material. The extension pipe, in conjunction with the spiral blades, lifts the plastic granules to the upper part of the mixing tank for further mixing, improving the uniformity of mixing. The motor at the top of the mixing tank provides power to the stirring shaft, driving the spiral blades and other components to work continuously, realizing the automation of plastic granule mixing and conveying, and improving production efficiency. The first and second dispersing rods on the outside of the extension pipe are connected to the inner wall of the mixing tank, dispersing the plastic granules in the mixing tank, breaking up material agglomeration, and simultaneously enhancing the extension pipe's... The installation ensures stability and stability when moving synchronously with the stirring shaft. The staggered distribution of the first and second dispersing rods increases the contact area and collision opportunities with the plastic granules, further improving material dispersion and making the mixing more uniform. This avoids insufficient mixing in certain areas. A return hole at the bottom of the extension tube allows some plastic granules to flow back from the extension tube to the guide hopper, achieving material circulation and extending the mixing time to ensure uniform mixing. The discharge pipe and valve on one side of the guide hopper facilitate precise control of the discharge of plastic granules after mixing, enabling seamless integration with subsequent production processes. The support base at the bottom of the support column increases the contact area with the ground, improving the overall stability of the device. The anti-slip texture at the bottom of the support base increases friction, preventing slippage during operation and ensuring smooth mixing. This invention effectively achieves three-dimensional mixing, improves mixing efficiency, and has high practical value. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

[0032] Please see Figures 1-5The extension pipe 11 has several return holes 1101 at its outer bottom end, which are evenly spaced. A discharge pipe 8 is installed at one bottom end of the guide hopper 2, and a discharge valve 9 is installed at one end of the discharge pipe 8. A support seat 7 is installed at the bottom end of the support column 6, and the bottom end of the support seat 7 has anti-slip texture. Through the return holes 1101 at the outer bottom end of the extension pipe 11, some plastic granules are returned from the extension pipe 11 to the guide hopper 2, realizing the circulation and stirring of materials, extending the stirring time, and ensuring that the plastic granules are mixed evenly. Through the discharge pipe 8 and discharge valve 9 on one side of the guide hopper 2, it is convenient to control the discharge of plastic granules after stirring, realize precise control of discharge, and facilitate the connection of subsequent production links. The support seat 7 at the bottom end of the support column 6 increases the contact area with the ground, improves the overall stability of the device, and the anti-slip texture at the bottom end of the support seat 7 increases friction, prevents the device from sliding during operation, and ensures the smooth operation of the stirring process.

[0033] Specifically, the working principle of this mixing device for plastic granule production is as follows: During use, the mixing tank 1 provides space for mixing plastic granules. The conveying pipe 3, hopper 4, and inlet 301 work together to input the plastic granules. The mixing tank 1 is supported by the support plate 5 and support column 6 to ensure stability. The stirring shaft 1001 of the stirring mechanism 10 drives the spiral blades 1002 to rotate, conveying and initially mixing the plastic granules in the conveying pipe 3. The spiral blades 1002, in contact with the inner wall of the conveying pipe 3, scrape off residual material. The extension pipe 11, in conjunction with the spiral blades 1002, lifts the plastic granules to the upper part of the mixing tank 1 for further mixing, improving the uniformity of the mixing. The motor 1003 at the top of the mixing tank 1 provides power to the stirring shaft 1001, driving the spiral blades 1002 and other components to work continuously, automating the mixing and conveying of plastic granules and improving production efficiency. The first dispersing rod 12 and the second dispersing rod 13 on the outside of the extension pipe 11 connect to the inner wall of the mixing tank 1, dispersing the plastic granules and breaking up the material. The agglomeration process enhances the installation stability of the extension tube 11, ensuring its stability when moving synchronously with the stirring shaft 1001. The staggered distribution of the first and second dispersing rods 12 and 13 increases the contact area and collision opportunities with the plastic granules, further improving the material dispersion effect and making the mixing more uniform. This avoids insufficient mixing in certain areas. Through the return hole 1101 at the bottom outer side of the extension tube 11, some plastic granules flow back from the extension tube 11 to the guide bucket 2, achieving material circulation and extending the mixing time to ensure uniform mixing of the plastic granules. The discharge pipe 8 and discharge valve 9 on one side of the guide bucket 2 facilitate control of the discharge of plastic granules after mixing, achieving precise control of the discharge and facilitating the connection with subsequent production stages. The support base 7 at the bottom of the support column 6 increases the contact area with the ground, improving the overall stability of the device. The anti-slip texture at the bottom of the support base 7 increases friction, preventing slippage during operation and ensuring smooth mixing. This invention effectively achieves three-dimensional mixing, improves mixing efficiency, and has high practical value.
