Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, and in particular to an automatic dust removal device based on rice processing. Background Technology

[0002] During rice processing, a large amount of dust such as bran and broken rice is generated. In order to prevent dust from polluting the workshop environment, cyclone dust collectors are used to separate the dust from the airflow using centrifugal force.

[0003] Currently, in existing cyclone dust collectors, dust-laden gas enters the collector through a fixed inlet. However, during rice processing, the flow rate and concentration of the dust-laden gas vary due to changes in production load. When the flow rate is high, the fixed inlet results in excessively high airflow velocity, increasing equipment resistance and potentially causing some dust to be discharged without effective separation. Conversely, when the flow rate is low, the airflow velocity is too low, resulting in insufficient centrifugal force and affecting dust removal efficiency. Therefore, we propose an automatic dust removal device based on rice processing to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic dust removal device based on rice processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic dust removal device for rice processing includes a cyclone dust collector installed inside a support frame. An air inlet is fixedly connected to the top of the cyclone dust collector, and a through-hole is formed inside the air inlet. A baffle is movably inserted inside the through-hole, and a connecting block is fixedly connected to the end of the baffle. Support rods are symmetrically connected to the upper and lower ends of the connecting block. A threaded groove is formed inside the upper support rod, and a threaded rod is horizontally inserted inside the threaded groove. The threaded rod is inserted into a fixed plate via a bearing, and the side of the fixed plate is fixedly connected to the air inlet.

[0007] In this device, a threaded rod and a baffle are installed. During use, the operator can adjust the lateral position of the baffle by rotating the motor. This allows for flexible adjustment of the air inlet size according to changes in the flow rate and concentration of dust-laden gas, improving dust removal efficiency and equipment adaptability.

[0008] Preferably, a rubber sleeve is glued to the outer side of the baffle, and the outer wall of the rubber sleeve is in contact with the inner wall of the air inlet.

[0009] Preferably, the lower support rod has a movable groove inside, and a connecting rod is inserted into the movable groove. The end of the connecting rod is fixedly connected to the inner side of the fixing plate.

[0010] Preferably, a motor is fixedly connected to the side of the threaded rod away from the support rod, and the outer wall of the motor is fixedly connected to the fixing plate.

[0011] Preferably, the upper and lower ends of the connecting block are symmetrically provided with limiting rods, and a rotating block is fixedly connected to the side of the limiting rods that are far apart from each other. The upper and lower ends of the connecting block are provided with positioning grooves that are adapted to the limiting rods.

[0012] Preferably, the inner wall of the positioning groove is provided with internal threads, and the outer surface of the limiting rod is provided with external threads.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This device is equipped with a threaded rod and a baffle. During use, the operator can adjust the lateral position of the baffle by rotating the motor. This allows for flexible adjustment of the air inlet size according to changes in the flow rate and concentration of dust-laden gas, thereby improving dust removal efficiency and equipment adaptability.

[0015] 2. By setting a limit rod and a rotating block, this device can protect the baffle and air inlet during use by using a rubber sleeve, and can ensure the sealing when the baffle moves laterally. The cooperation between the limit rod and the rotating block can realize the quick replacement of the worn baffle, thereby effectively improving the convenience of the device during maintenance.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 An automatic dust removal device based on rice processing includes a cyclone dust collector 1, which is installed inside a support frame 14. An air inlet 2 is fixedly connected to the top of the cyclone dust collector 1, and a through-hole 13 is opened inside the air inlet 2. A baffle 3 is movably inserted inside the through-hole 13, and a connecting block 4 is fixedly connected to the end of the baffle 3. Support rods 5 are symmetrically connected to the upper and lower ends of the connecting block 4. A threaded groove is opened inside the upper support rod 5, and a threaded rod 6 is horizontally inserted inside the threaded groove. The threaded rod 6 is inserted into the inside of a fixed plate 7 through a bearing, and the side of the fixed plate 7 is fixedly connected to the air inlet 2.

[0024] Furthermore, refer to Figure 3 and Figure 5 It can be seen that the outer side of the baffle 3 is glued with a rubber sleeve 8, and the outer wall of the rubber sleeve 8 is in contact with the inner wall of the air inlet 2. In use, the glued rubber sleeve 8 can protect the outer wall of the baffle 3 and effectively ensure the sealing when the baffle 3 is inserted into the through-hole 13 inside the air inlet 2.

[0025] Furthermore, refer to Figure 3 and Figure 5 It can be seen that the lower support rod 5 has a moving groove inside, and a connecting rod 10 is inserted inside the moving groove. The end of the connecting rod 10 is fixedly connected to the inner side of the fixed plate 7. In use, the baffle 3 can be guided laterally by the cooperation of the motor 9 and the connecting rod 10, thereby effectively ensuring the stable lateral movement of the baffle 3.

[0026] Furthermore, refer to Figure 3 and Figure 4It can be seen that a motor 9 is fixedly connected to the side of the threaded rod 6 away from the support rod 5, and the outer wall of the motor 9 is fixedly connected to the fixing plate 7. A sensor is installed inside the air inlet 2, which is not shown in the figure. The sensor is used to detect the flow rate and concentration of dust-laden gas and transmit the detection signal to the controller. The controller controls the action of the motor 9 according to the detection signal, thereby driving the automatic opening and closing of the motor 9 to adjust the position of the baffle 3, thereby realizing the automatic adjustment of the size of the air inlet 2. The principle of the motor 9 driving the threaded rod 6 to rotate is existing technology and will not be described in detail here. The setting of the motor 9 can improve the convenience of using this device.

[0027] Furthermore, refer to Figure 4 It can be seen that the upper and lower ends of the connecting block 4 are symmetrically inserted with limiting rods 11, and the side of the limiting rods 11 that is far away from each other is fixedly connected with a rotating block 12. The upper and lower ends of the connecting block 4 are provided with positioning grooves that are compatible with the limiting rods 11. Through the cooperation of the limiting rods 11 and the rotating block 12, the disassembly and assembly requirements of the connecting block 4 and the support rod 5 can be met, so that the damaged baffle 3 can be replaced.

[0028] Furthermore, refer to Figure 4 It can be seen that the inner wall of the positioning groove is provided with internal threads, and the outer surface of the limiting rod 11 is provided with external threads. Through the cooperation between the positioning groove and the limiting rod 11, the tightness of the connection between the connecting block 4 and the baffle 3 can be guaranteed.

[0029] Working Principle: When using this utility model, the operator can first place the support frame 14 in a suitable area, and then connect it to the corresponding pipes through bolts and air inlet 2. Through the setting of air inlet 2, the dust-laden gas can be transported into the interior of the cyclone dust collector 1 for dust removal. During the dust removal process, when the airflow speed is too high or too low, the operator can start the forward and reverse rotation of the motor 9, which will drive the threaded rod 6 to rotate simultaneously. At this time, the threaded rod 6 can engage with the support rod 5 to drive the connecting block 4 and the baffle 3 to move laterally, thereby adjusting the distance between the baffle 3 and the inner wall of the cyclone dust collector 1, so as to flexibly adjust the size of the air inlet 2, and improve the dust removal efficiency and adaptability of the device. The above is the complete working principle of this utility model.

As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.
