Description

Technical Field

[0001] This application relates to the technical field of plastic pellet processing equipment, specifically a feeding device for a cleanroom. Background Technology

[0002] With the increasing demand for plastic products, plastic masterbatch, as an important intermediate, has become a key focus of the industry in terms of processing quality and efficiency. Currently, the production equipment and technology in the plastic masterbatch processing industry are quite mature, but the challenge of improving the purity of the finished product remains. In actual production, to ensure the quality of the final product, screening devices are usually installed at the front end of the production line to remove impurities from the raw materials. The processed masterbatch is then fed into subsequent purification processes through various feeding devices.

[0003] In existing technologies, the method of conveying plastic masterbatch to the purification chamber usually adopts spiral blade conveying. However, the power of the motor to drive the spiral blade is still insufficient when facing a high tilt angle, resulting in low conveying efficiency. Furthermore, during the conveying process, the plastic particles stick to the inner wall of the pipe due to the triboelectric effect, which makes it impossible to lift and convey the plastic particles stably. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a feeding device for a cleanroom, which has advantages such as high-efficiency conveying and solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, this application provides the following technical solution: a feeding device for a cleanroom, comprising a base and a cleanroom body, a conveying pipe above the base, a vibration mechanism on the outer surface of the conveying pipe, the vibration mechanism comprising a support frame fixedly connected to the surface of the conveying pipe, a first motor fixedly installed on the inner wall of the support frame, a turntable fixedly connected to the output end of the first motor, a fixed column fixedly connected to the outer surface of the turntable, a movable frame outside the fixed column, two symmetrical hammer blocks fixedly connected to the outer surface of the movable frame, the inner wall of the conveying pipe communicating with the inner wall of the cleanroom body, a negative pressure fan fixedly installed on the outer surface of the cleanroom body, and the output end of the negative pressure fan communicating with the inner wall of the conveying pipe.

[0006] The above scheme, by setting up a negative pressure fan, creates a low-pressure zone at the material conveying end of the conveying pipeline, thereby attracting outside air to flow in. This causes the material to be drawn in along with the airflow, thus assisting in the material conveying. This reduces the demand for motor power, improves conveying efficiency, and lowers operating costs. Furthermore, when the first motor drives the turntable to rotate, causing the fixed column to move in a circular motion, it can drive the moving frame to move left and right repeatedly. This causes the hammer block to continuously hammer the inner wall of the conveying pipeline, causing the conveying pipeline to vibrate continuously. This vibration dislodges the particles adsorbed on the inner wall of the conveying pipeline, thus keeping the pipeline unobstructed, ensuring the continuity and stability of material conveying, and improving the material conveying efficiency.

[0007] Furthermore, the vibration mechanism also includes an annular frame fixedly connected to the outer surface of the conveying pipe. The outer surface of the annular frame has two symmetrical slots. The inner walls of the two slots are provided with guide grooves. The inner walls of the two guide grooves and the outer surfaces of the two hammer blocks are fixedly connected to two symmetrical sliders, and the outer surfaces of the sliders are slidably connected to the inner walls of the guide grooves.

[0008] The above scheme, by setting up sliders and guide grooves, can guide and limit the movement of the moving frame, so that the hammer block can stably hammer the surface of the conveying pipeline.

[0009] Furthermore, the outer surface of the movable frame is provided with a sliding groove, and the outer surface of the fixed column is slidably connected to the inner wall of the sliding groove.

[0010] With the above scheme, by setting up the chute, when the fixed column makes a circular motion, the fixed column slides on the inner wall of the chute, thereby driving the moving frame to make repeated left and right movements, and thereby driving the hammer block to hammer the surface of the conveying pipeline.

[0011] Furthermore, the sides of the two hammer blocks that are close to each other are covered with rubber pads.

[0012] The above solution utilizes the hammering block to protect the conveying pipeline from damage caused by the impact when the hammering block strikes the pipeline.

[0013] Furthermore, a rotating shaft is rotatably connected to the inner wall of the conveying pipe, and a spiral blade is fixedly connected to the outer surface of the rotating shaft.

[0014] The above scheme, by setting up a rotating shaft and spiral blades, can stably lift and transport the material inside the conveying pipeline when the rotating shaft drives the spiral blades to rotate, thereby improving the working efficiency of the device.

[0015] Furthermore, a second motor is fixedly connected to one end of the rotating shaft, and the outer surface of the second motor is fixedly embedded in the outer surface of the conveying pipe.

[0016] The above solution, by setting up a second motor, can efficiently drive the rotation of the shaft, ensuring stable material conveying.

[0017] Furthermore, a feed hopper is fixedly installed on the outer surface of the conveying pipe.

[0018] The above scheme connects the conveying pipeline to the outside air by setting up a feeding hopper. Under the negative pressure at the other end of the conveying pipeline, the material can be conveyed in an auxiliary manner, thereby improving the conveying efficiency of the device.

[0019] Furthermore, two supports are fixedly connected to the outer surface of the conveying pipe, and the conveying pipe and the base are fixedly connected by the supports.

[0020] With the above solution, when the conveying pipeline is in operation, the two supports can effectively support the conveying pipeline, thereby ensuring the stable conveying of materials.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This type of feeding device for a purification chamber, by using a negative pressure fan, creates a low-pressure zone at the conveying end of the conveying pipeline, thereby attracting outside air to flow in. This causes the material to be drawn in along with the airflow, thus assisting in the material conveying. This reduces the power requirement of the motor, improves conveying efficiency, and lowers operating costs. Furthermore, when the first motor drives the turntable to rotate, causing the fixed column to move in a circular motion, it can drive the moving frame to move left and right repeatedly. This causes the hammer block to continuously hammer the inner wall of the conveying pipeline, causing the conveying pipeline to vibrate continuously. This vibration dislodges the particles adsorbed on the inner wall of the conveying pipeline, thus keeping the pipeline unobstructed, ensuring the continuity and stability of material conveying, and improving the material conveying efficiency.

Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] See also Figure 1 , Figure 3 and Figure 4 This embodiment of a feeding device for a purification chamber includes a base 1 and a purification chamber body 5. A conveying pipe 2 is provided above the base 1. A vibration mechanism 3 is provided on the outer surface of the conveying pipe 2. The vibration mechanism 3 includes a support frame 306 fixedly connected to the surface of the conveying pipe 2. A first motor 307 is fixedly installed on the inner wall of the support frame 306. A turntable 308 is fixedly connected to the output end of the first motor 307. A fixed column 309 is fixedly connected to the outer surface of the turntable 308. A movable frame 310 is provided outside the fixed column 309. Two symmetrical hammer blocks 304 are fixedly connected to the outer surface of the movable frame 310. When the first motor 307 drives the turntable 308 to rotate, causing the fixed column 309 to perform circular motion, it can drive the movable frame 310 to perform repetitive left and right movements. The hammer block 304 continuously hammers the inner wall of the conveying pipe 2, causing the conveying pipe 2 to vibrate continuously. This vibrates and dislodges the particles adsorbed on the inner wall of the conveying pipe 2, thus keeping the pipe unobstructed, ensuring the continuity and stability of material conveying, and improving the material conveying efficiency. The inner wall of the conveying pipe 2 is connected to the inner wall of the purification chamber body 5. A negative pressure fan 4 is fixedly installed on the outer surface of the purification chamber body 5. By setting the negative pressure fan 4, a low-pressure zone can be formed at the conveying end of the conveying pipe 2, thereby attracting outside air to flow in. This causes the material to be drawn in with the airflow, thereby assisting in the material conveying, reducing the demand for motor power, improving conveying efficiency, and reducing operating costs. The output end of the negative pressure fan 4 is connected to the inner wall of the conveying pipe 2.

[0031] See also Figure 3 and Figure 4The vibration mechanism 3 also includes an annular frame 301 fixedly connected to the outer surface of the conveying pipe 2. Two symmetrical slots 302 are formed on the outer surface of the annular frame 301. Guide grooves 303 are formed on the inner walls of both slots 302. Two symmetrical sliders 305 are fixedly connected to the inner walls of the guide grooves 303 and the outer surfaces of the two hammer blocks 304. The outer surfaces of the sliders 305 are slidably connected to the inner walls of the guide grooves 303. By setting the sliders 305 and the guide grooves 303, the movement of the movable frame 310 can be guided and limited, allowing the hammer blocks 304 to stably hammer the surface of the conveying pipe 2. A sliding groove is formed on the outer surface of the movable frame 310. 311. The outer surface of the fixed column 309 is slidably connected to the inner wall of the slide groove 311. By setting the slide groove 311, when the fixed column 309 makes a circular motion, it slides on the inner wall of the slide groove 311, thereby driving the moving frame 310 to make repeated left and right movements, and thereby driving the hammer block 304 to hammer the surface of the conveying pipe 2. The two hammer blocks 304 are covered with rubber pads on the side that are close to each other. By setting the hammer block 304, when the hammer block 304 hammers the conveying pipe 2, the rubber pads covering the surface can effectively protect the conveying pipe 2 and prevent the hammer from damaging the surface of the conveying pipe 2.

[0032] See also Figure 1 and Figure 2 A rotating shaft 6 is rotatably connected to the inner wall of the conveying pipe 2. A spiral blade 7 is fixedly connected to the outer surface of the rotating shaft 6. By setting the rotating shaft 6 and the spiral blade 7, when the rotating shaft 6 drives the spiral blade 7 to rotate, it can stably lift and convey the material inside the conveying pipe 2, thereby improving the working efficiency of the device. A second motor 9 is fixedly connected to one end of the rotating shaft 6. The outer surface of the second motor 9 is fixedly embedded in the outer surface of the conveying pipe 2. By setting the second motor 9, it can efficiently drive the rotation of the rotating shaft 6, ensuring the stable conveying of materials. A feed hopper 8 is fixedly installed on the outer surface of the conveying pipe 2. By setting the feed hopper 8, the conveying pipe 2 is connected to the external air. At this time, under the negative pressure at the other end of the conveying pipe 2, it can assist in conveying materials, thereby improving the conveying efficiency of the device. Two supports are fixedly connected to the outer surface of the conveying pipe 2. The conveying pipe 2 and the base 1 are fixedly connected by the supports. When the conveying pipe 2 is working, the two supports can effectively support the conveying pipe 2, thereby ensuring the stable conveying of materials by the conveying pipe 2.

[0033] In this embodiment, a feeding device for a purification chamber, by setting up a negative pressure fan 4, can create a low-pressure zone at the conveying end of the conveying pipe 2, thereby attracting outside air to flow in. This causes the material to be drawn in along with the airflow, thus assisting in the material conveying. This reduces the demand for motor power, improves conveying efficiency, and lowers operating costs. Furthermore, when the first motor 307 drives the turntable 308 to rotate, causing the fixed column 309 to move in a circular motion, it can drive the moving frame 310 to move left and right repeatedly. This causes the hammer block 304 to continuously hammer the inner wall of the conveying pipe 2, causing the conveying pipe 2 to vibrate continuously. This vibrates and dislodges the particles adsorbed on the inner wall of the conveying pipe 2, thereby keeping the pipe unobstructed, ensuring the continuity and stability of material conveying, and improving the material conveying efficiency.

[0034] It should be noted that the second motor 9 is installed on the surface of the purification chamber body 5 at the end of the conveying pipe 2, thereby stably lifting and conveying materials. Furthermore, the conveying pipe 2 is made of stainless steel with a smooth inner wall to reduce frictional resistance and improve conveying efficiency.

[0035] The working principle of the above embodiment is as follows: When using this device, the second motor 9 is first started to drive the rotation of the shaft 6 and the spiral blade 7, thereby stably driving the material inside the conveying pipe 2 to be lifted and conveyed to the interior of the purification chamber body 5. At this time, the negative pressure fan 4 forms a low pressure zone at the material conveying end of the conveying pipe 2, and connects the conveying pipe 2 with the external air through the feed hopper 8. At this time, the negative pressure at the other end of the conveying pipe 2 assists in conveying the material, thereby improving the conveying efficiency. Then, during the conveying process, the first motor 307 drives the turntable 308 to rotate, causing the fixed column 309 to perform circumferential motion. At this time, the fixed column 309 slides on the inner wall of the slide groove 311, thereby driving the moving frame 310 to perform left and right repeated movements. Under the limiting guidance of the guide groove 303, the moving frame 310 can move stably in a directional direction, thereby enabling the hammer block 304 to stably hammer the surface of the conveying pipe 2, causing the conveying pipe 2 to vibrate continuously, thereby vibrating and dislodging the particles adsorbed on the inner wall of the conveying pipe 2, thereby keeping the pipe unobstructed.
