Description

Technical Field

[0001] This utility model relates to the field of plastic particle mixing technology, and specifically to a plastic particle mixing device for improving mixing uniformity. Background Technology

[0002] Plastics processing, as a large-scale and crucial production branch within the plastics industry, focuses on transforming synthetic resins or plastics into various plastic products through various processes. In the plastics processing flow, the batching process is an indispensable preliminary step, requiring the precise mixing of multiple raw materials according to specific proportions. Raw material mixing is a key operation to ensure uniform mixing.

[0003] A search revealed that patent CN216609639U discloses a plastic granule mixer for plastic processing. While this device ensures uniform mixing during use, and the counterweight extends outwards from the mixing head due to centrifugal force as the mixing head rotates, thus expanding the mixing range and increasing the mixing efficiency of plastic granules, there are still technical problems that urgently need to be solved. Firstly, dust is inevitably generated during the mixing of various materials. Without an effective collection and treatment mechanism, the dust concentration in the processing workshop can easily exceed standards, seriously endangering the health of operators and polluting the surrounding environment. Secondly, debris is inevitably generated after mixing various materials. This debris easily adheres to the inner walls of the equipment and the mixing paddle, greatly hindering daily cleaning and maintenance. Therefore, further improvements are needed.

[0006] A plastic granule mixing device for improving mixing uniformity includes a mixing tank, a drive motor installed on the mixing tank, and a mixing blade installed on the output end of the drive motor via a rotating shaft. The mixing blade is disposed inside the mixing tank.

[0007] The inner wall of the mixing tank is equipped with a gas collection hood and an exhaust pipe. The gas collection hood is used to suck up the dust and debris generated during mixing and blowing inside the mixing tank. A first air pump is installed on the top surface of the mixing tank.

[0008] The rear end face of the mixing tank is fitted with a housing via a mounting bracket, and a filter bag is installed inside the housing.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, a cover plate is installed on the mixing tank via a hinge, and a handle is installed on the cover plate.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] The hinged cover allows for flexible opening and closing, facilitating the addition of plastic granules to the mixing tank or the inspection and maintenance of the tank's interior after mixing. The handle design optimizes the operating experience of the cover, making it easy for staff to open and close, while also providing a stable point of leverage during operation.

[0013] Furthermore, a support frame is fixedly installed on the bottom end face of the mixing tank, and an anti-slip pad is fitted onto the bottom end face of the support frame.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The support frame provides structural support for the mixing tank, and the anti-slip pads increase the friction between the equipment and the ground.

[0016] Furthermore, a discharge pipe is embedded and fixed at the bottom end of the mixing tank, the discharge pipe is connected to the mixing tank, and a valve is installed on the discharge pipe.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0019] Furthermore, a nozzle is installed on the bottom end face of the exhaust pipe, and the nozzle is in communication with the gas in the exhaust pipe. The nozzle is used to blow and clean the inside of the mixing tank by exhausting gas.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] The nozzle can spray the gas in the exhaust pipe into the mixing tank in the form of a high-pressure jet, which can effectively remove residual plastic particles and dust adhering to the inner wall of the mixing tank, the mixing blades, and the corners of the tank. This cleaning method does not require manual disassembly of parts for cleaning, reducing cleaning time and labor costs, and improving the reuse efficiency of the equipment.

[0022] Furthermore, the first air pump is provided with an air inlet pipe, and the end of the air inlet pipe facing away from the first air pump is embedded and fixed inside the exhaust pipe.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] The first air pump is connected to the air inlet pipe and the air outlet pipe, which can stably provide the high-pressure gas required for cleaning to the nozzle, forming a continuous and powerful blowing force, ensuring the reliability and stability of the blowing cleaning effect, and guaranteeing the operation of the equipment's cleaning function.

[0025] Furthermore, a second air pump is installed on the rear end face of the box, the second air pump is connected to the gas in the box through a second extraction pipe, and the box is connected to the gas in the gas collection hood through a first extraction pipe.

[0026] The beneficial effects of adopting the above-mentioned further solutions are:

[0027] The second air pump, acting as a power source, forms a negative pressure airflow channel through the second extraction pipe and the first extraction pipe. This channel draws the gas collected by the gas collection hood (such as dust generated by stirring and dust debris generated by jet cleaning) into the chamber. The filter bag filters the dust-laden gas, trapping the dust inside the chamber. The purified gas is then discharged, effectively reducing the spillage of dust generated during stirring, improving the air quality in the production workshop, and protecting the health of the operators.

[0028] This invention provides a plastic granule mixing device to improve mixing uniformity. It has the following beneficial effects:

[0029] The mixing blades are rotated by a drive motor to achieve thorough mixing of plastic granules and ensure product quality uniformity.

[0030] The integrated nozzle blowing system can clean the inner wall and components of the tank before and after mixing, reducing manual maintenance costs, shortening equipment downtime, and improving production efficiency.

[0031] The equipped dust collection hood and filter bag filtration system effectively capture dust and debris generated during the mixing and cleaning process, preventing dust from overflowing and polluting the workshop environment.

[0032] The dual-pump design (the first pump is used for blowing and cleaning, and the second pump is used for dust collection) ensures functional independence, improves system reliability, and enhances ease of maintenance. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Please see Figures 1 to 3 As shown, the embodiments provided by this utility model are as follows:

[0042] Example 1

[0043] A plastic granule mixing device for improving mixing uniformity includes a mixing tank 1, a drive motor 2 installed on the mixing tank 1, and a stirring blade 21 installed on the output end of the drive motor 2 via a rotating shaft 22. The stirring blade 21 is disposed inside the mixing tank 1.

[0044] The inner wall of the mixing tank 1 is equipped with a gas collection hood 42 and an exhaust pipe 31. The gas collection hood 42 is used to suck up the dust and debris generated during mixing and blowing in the mixing tank 1. The top surface of the mixing tank 1 is equipped with a first air pump 3.

[0045] A housing 4 is mounted on the rear end face of the mixing tank 1 via a mounting bracket 43, and a filter bag 44 is installed inside the housing 4.

[0046] A cover plate 12 is installed on the mixing tank 1 via a hinge. A handle is installed on the cover plate 12. The cover plate 12, connected by the hinge, can be opened and closed flexibly, which is convenient for operators to add plastic granule raw materials into the mixing tank 1, or to inspect and maintain the inside of the tank after mixing. The handle optimizes the operating experience of the cover plate 12, making it easy for operators to open and close the cover plate 12, and providing a stable point of force during operation.

[0047] A support frame 11 is fixedly installed on the bottom end face of the mixing tank 1. Anti-slip pads are fitted on the bottom end face of the support frame 11. The support frame 11 provides a support structure for the mixing tank 1, and the anti-slip pads increase the friction between the equipment and the ground.

[0048] A discharge pipe 13 is embedded and fixed at the bottom end of the mixing tank 1. The discharge pipe 13 is connected to the mixing tank 1. A valve is installed on the discharge pipe 13. The discharge pipe 13 is designed so that the plastic granules after being mixed can be discharged smoothly. The valve can control the discharge speed and discharge volume, which can be adjusted according to the needs of the subsequent production process.

[0049] A second air pump 45 is installed on the rear end face of the housing 4. The second air pump 45 is connected to the housing 4 in gas communication through the second extraction pipe 46. The housing 4 is connected to the gas collection hood 42 in gas communication through the first extraction pipe 41. The second air pump 45 serves as a power source and forms a negative pressure airflow channel through the second extraction pipe 46 and the first extraction pipe 41. This allows the gas collected by the gas collection hood 42 (such as dust generated by stirring and dust debris generated by spray cleaning) to be sucked into the housing 4. The filter bag 44 filters the dust-laden gas, trapping the dust inside the housing 4. The purified gas is then discharged, effectively reducing the overflow of dust generated during stirring, improving the air quality in the production workshop, and protecting the health of the operators.

[0050] Example 2

[0051] To perform a spray cleaning of the interior after mixing and agitation, for example, such as Figures 1 to 3 As shown, this utility model also includes:

[0052] A nozzle 32 is installed on the bottom end of the exhaust pipe 31. The nozzle 32 is connected to the exhaust pipe 31 for gas communication. The nozzle 32 is used to blow and clean the inside of the mixing tank 1 by exhausting the gas. The nozzle 32 can spray the gas in the exhaust pipe 31 into the inside of the mixing tank 1 in the form of high-pressure jet, which can effectively remove residual plastic particles and dust adhering to the inner wall of the mixing tank 1, the mixing blades 21 and the corners of the tank. This cleaning method does not require manual disassembly of parts for cleaning, reducing cleaning time and labor costs, and improving the reuse efficiency of the equipment.

[0053] The first air pump 3 is equipped with an air inlet pipe 33. The end of the air inlet pipe 33 facing away from the first air pump 3 is embedded and fixed in the exhaust pipe 31. The first air pump 3 is connected to the exhaust pipe 31 through the air inlet pipe 33, which can stably provide the nozzle 32 with the high-pressure gas required for cleaning, forming a continuous and strong blowing power, ensuring the reliability and stability of the blowing cleaning effect, and ensuring the operation of the equipment's cleaning function.

[0054] Working principle:

[0055] Adding ingredients:

[0056] The operator opens the cover 12 (connected to the mixing tank 1 via a hinge) using the handle and pours the plastic granule raw material into the mixing tank 1.

[0057] Stir and mix:

[0058] The drive motor 2 starts and drives the stirring blades 21 to rotate through the rotating shaft 22, which fully stirs and mixes the plastic particles in the tank to ensure the uniformity of product quality.

[0059] Purge cleaning (optional operation before or after stirring):

[0060] The first air pump 3 starts and delivers gas to the exhaust pipe 31 through the air intake pipe 33.

[0061] Gas is injected at high pressure through nozzle 32 onto the inner wall of mixing tank 1, mixing blades 21 and corners to remove residual particles and dust.

[0062] This process eliminates the need to disassemble parts, reducing labor maintenance costs and equipment downtime.

[0063] Dust collection:

[0064] The second air pump 45 is activated, creating negative pressure inside the housing 4 through the second extraction pipe 46.

[0065] The gas collection hood 42 captures the dust and debris generated during the stirring and blowing process, and draws the dust-laden gas into the housing 4 through the first extraction pipe 41.

[0066] Filter bag 44 intercepts dust, and the purified gas is discharged, preventing dust from overflowing and polluting the workshop environment.

[0067] Material discharge control:

[0068] After mixing is complete, open the valve on the discharge pipe 13, and the plastic granules will be discharged through the discharge pipe 13. The valve can adjust the discharge speed and amount.
