Description

Technical Field

[0001] This utility model relates to the field of refractory brick processing technology, and in particular to an exhaust component for a hopper. Background Technology

[0002] The processing of refractory bricks requires the preparation of powder and aggregates, followed by mixing and pressing. Currently, automated preparation production lines are commonly used to control the accuracy of the preparation process and to automate the process. These lines typically have multiple storage tanks and at least one movable hopper used for weighing, transferring, and feeding raw materials into the mixing unit. To prevent dust generation and facilitate material feeding during material handling and transfer, an exhaust pipe is usually installed on the hopper. Currently, the exhaust pipe is lined with a filter cloth to prevent dust from escaping. However, over time, dust adheres to the filter cloth, affecting airflow. To avoid this, the filter cloth needs to be cleaned or replaced periodically. Cleaning and replacement affect the material preparation process and increase production costs. Utility Model Content

[0003] This utility model provides an exhaust component for a hopper to overcome the shortcomings of the prior art and solve the problem that the filter component is easily clogged by dust, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A venting component for a hopper includes a rectangular outer shell. The lower end of the rectangular outer shell is connected to a discharge pipe, and the upper end of the rectangular outer shell is bolted to a top cover plate. The top cover plate has a feed inlet, and a feed pipe is welded to the feed inlet. An inclined tube is connected to the top cover plate, and the lower end of the inclined tube is welded to the top cover plate. The outer end of the inclined tube has a first protruding edge, and an inner tube is provided inside the outer end of the inclined tube. The outer end of the inner tube has a second protruding edge, and a conical filter cover is provided inside the inner tube. The outer end of the conical filter cover is the smaller end, and multiple holes are provided on the conical filter cover. The inverted conical cover can improve the filtration effect of air and also avoid dust clogging of the holes. The connecting parts are set in an inclined state to facilitate the natural return of dust into the hopper.

[0005] Furthermore, an inner ring is formed on the lower inner circumference of the inner tube, and an inner groove is formed on the lower open end of the inner ring. A lower extension ring is formed on the lower end of the conical filter cover, and multiple inner plates are formed on the outer circumference of the lower extension ring. The inner plates pass through the inner groove, and the conical filter cover is movably mounted on the inner ring. When cleaning it, the dust on it can be shaken off.

[0006] Furthermore, a third protrusion is bolted to the second protrusion and the first protrusion. The third protrusion is provided with an exhaust head, and multiple exhaust holes are opened on the outer periphery of the exhaust head. The air can be filtered again through the exhaust head to prevent dust from being discharged and polluting the environment.

[0007] Furthermore, a motor is bolted to the outer end of the exhaust head, and a rotating shaft is connected to the output shaft of the motor. The rotating shaft passes through the exhaust head, and an inner disc is provided on the inner end of the rotating shaft. An extended tube is welded to the outer end of the conical filter cover. V-shaped grooves are arranged in a circumferential array on the outer end of the extended tube. A rotating pressure rod is provided on the rotating shaft, and the outer circumference of the rotating pressure rod abuts against the outer end of the extended tube. A washer is fitted on the inner end of the rotating shaft, and the inner end of the washer is tangent to the outer end of the inner disc. A spring is fitted on the rotating shaft, and the spring is located between the conical filter cover and the washer. When the motor drives the rotating shaft to rotate, the rotating pressure rod on it will act on the outer end of the extended tube, thereby causing the extended tube to continuously reciprocate under the action of the rotating pressure rod and the spring, thus shaking off the dust adhering to the conical filter cover.

[0008] Furthermore, a guide groove is provided on the outer circumference of the rotating shaft, and a collar is fitted on the rotating shaft. Multiple guide blocks are provided inside the collar and are inserted into the guide groove. Multiple scrapers are welded to the outer circumference of the collar. The outer wall of the scraper is tangent to the inner wall of the conical filter cover. A spring is located between the washer ring and the collar. The scraper can scrape off the dust on the inner wall of the conical filter cover, thereby ensuring the smoothness of air discharge.

[0009] The advantages of the above technical solution are: This invention not only avoids dust emissions that could pollute the environment, but also scrapes off the dust to prevent it from affecting air circulation. Attached Figure Description

[0015] Figure 5 A three-dimensional structural diagram of the conical filter hood is shown. Detailed Implementation

[0016] like Figures 1-5 As shown, a venting component for a hopper includes a rectangular outer shell 1. The lower end of the rectangular outer shell 1 is connected to a discharge pipe 10. The upper end of the rectangular outer shell 1 is bolted to a top cover plate 11. A feed inlet is provided on the top cover plate 11, and a feed pipe 12 is welded to the feed inlet. An inclined pipe 2 is connected to the top cover plate 11. The lower end of the inclined pipe 2 is welded to the top cover plate 11. A first protruding edge 20 is formed on the outer end of the inclined pipe 2. An inner pipe 27 is provided inside the outer end of the inclined pipe 2. A second protruding edge 21 is provided on the outer end of the inner pipe 27. A conical filter cover is provided inside the inner pipe 27. The outer end of the conical filter cover is the smaller end, and multiple holes 32 are provided on the conical filter cover.

[0017] A third protruding edge 22 is bolted to the second protruding edge 21 and the first protruding edge 20. The third protruding edge 22 is provided with an exhaust head 23, and multiple exhaust holes 24 are opened on the outer periphery of the exhaust head 23. The lower end of the inner tube 27 is formed with an inner ring 28, and the lower end of the inner ring 28 is formed with an inset groove 29. The lower end of the conical filter cover is formed with a lower extension ring 30, and multiple inset plates 31 are formed on the outer periphery of the lower extension ring 30. The inset plates 31 pass through the inset groove 29. A motor 25 is bolted to the outer end of the exhaust head 23. A rotating shaft 26 is connected to the output shaft of the motor 25. The rotating shaft 26 passes through the exhaust head 23. An inner plate 36 is provided on the inner end of the rotating shaft 26. An extension tube 33 is welded to the outer end of the conical filter cover. V-shaped grooves 34 are arranged in a circumferential array on the outer end of the extension tube 33. A rotating pressure rod 35 is provided on the rotating shaft 26. The outer circumference of the rotating pressure rod 35 abuts against the outer end of the extension tube 33. A washer 37 is sleeved on the inner end of the rotating shaft 26. The inner end of the washer 37 is tangent to the outer end of the inner plate 36. A spring 38 is sleeved on the rotating shaft 26. The spring 38 is located between the conical filter cover and the washer 37. A guide groove 39 is provided on the outer periphery of the rotating shaft 26, and a collar 40 is fitted on the rotating shaft 26. Multiple guide blocks are provided inside the collar 40 and are inserted into the guide groove 39. Multiple scrapers 41 are welded to the outer periphery of the collar 40. The outer wall of the scraper 41 is tangent to the inner wall of the conical filter cover. The spring 38 is located between the gasket 37 and the collar 40.

[0018] When raw materials are injected or discharged, dust will inevitably form inside the rectangular outer shell 1. The dust will be discharged outward through the inclined tube 2. During the discharge process, the conical filter cover will block the dust, while air is discharged through the exhaust port 24 and the orifice 32. The dust will adhere to the inner wall of the conical filter cover. Then, the motor 25 is started, and the rotating shaft 26 rotates under the drive of the motor 25. When the rotating shaft 26 rotates, it will drive the scraper 41 to rotate. The outer wall of the scraper 41 is tangent to the inner wall of the conical filter cover, so it can scrape off the dust adhering to the inner wall of the conical filter cover. When the scraper 41 rotates, the rotating pressure rod 35 will also rotate. As the rotating pressure rod 35 rotates, it will act on the V-shaped groove 34 and the end of the extension tube 33, so that the conical filter cover will reciprocate under the action of the spring 38 and the rotating pressure rod 35, thereby shaking off the dust in the orifice 32. During vibration, when the rotating pressure rod 35 acts on the end of the extension tube 33, the spring 38 will be in a compressed state, while when the rotating pressure rod 35 is at the bottom of the V-groove 34, the spring 38 will be in a naturally extended state, thus causing the conical filter cover to vibrate.

[0019] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
