Description

Technical Field

[0001] This utility model relates to the field of material conveying equipment technology, and in particular to a dustproof device for a feed inlet. Background Technology

[0002] In the chemical, food, and pharmaceutical production industries, the feed inlets of reaction vessels or mixing tanks are usually connected via flanges to facilitate the transport of powdery or granular materials. Traditional flange connections require the use of multiple bolts and nuts for fixing. During installation, the bolt holes must be aligned one by one and the nuts tightened sequentially. During disassembly, they must also be loosened one by one. This connection method involves numerous steps, consuming a lot of time and manpower. Especially in situations where frequent disassembly and cleaning are required, the work efficiency is low, affecting the overall production process.

[0003] To prevent dust spillage during material descent, existing technologies typically employ dust covers at the feed inlet. However, these dust covers are generally simple in structure and have limited ability to block and collect fine dust carried by the airflow generated by high-speed falling materials. As a result, some dust still diffuses into the production environment, causing pollution and posing a threat to the health of operators. While some improved dust covers have internal baffles to enhance the interception effect, the intercepted material particles accumulate directly on the surface of the baffles. When the material has a certain degree of stickiness or poor flowability, it can form clumps and blockages, hindering the smooth descent of subsequent materials and requiring manual cleaning, thus interrupting the continuity of production.

[0004] Therefore, this utility model proposes a dustproof device for the feed inlet to overcome the shortcomings of the prior art. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an automatic positioning and die-cutting device for label production, which aims to improve the problems in the prior art.

[0006] In view of the problems of cumbersome and time-consuming installation process, insufficient connection reliability, poor interception effect of floating dust and easy material accumulation and blockage in the existing dust prevention device for the feed inlet, this utility model aims to provide a dust prevention device for the feed inlet with improved structure that can effectively solve the above problems.

[0007] This utility model provides a dustproof device for a feed inlet, including: a feed pipe, an upper flange, a lower flange, a dust cover; as well as a locking mechanism, a guide plate, a baffle, a trough, and a pointed slider.

[0008] The locking mechanism consists of a first clamp rotatably connected to the upper flange and a second clamp rotatably connected to the first clamp. The end of the first clamp is provided with a locking block, and the end of the second clamp is provided with a locking groove that cooperates with the locking block.

[0009] Furthermore, the guide plate is rotatably connected to the top of the dust cover, the baffle is fixedly connected to the bottom of the inner wall of the guide plate, and the trough and the pointed slider are arranged around the bottom of the baffle. The upper flange and the lower flange are engaged and connected from the outer wall by the first and second clamps of the locking mechanism. At the same time, the guide plate, baffle, trough and pointed slider form a dustproof and flow guiding combination structure inside the dust cover.

[0010] Preferably, the locking mechanism further includes a pin, and the second clamp has a through hole for the pin to be inserted. The pin is used to pass through the second clamp and through the block after the block is engaged with the slot to achieve locking.

[0011] Preferably, a curved ring plate is fixedly connected to the inner wall of the baffle.

[0012] Preferably, the curved ring plate and the baffle together form a buffer cavity for receiving and buffering material particles.

[0013] Preferably, the pointed slider and the trough are arranged in an overlapping manner along the bottom circumference of the baffle.

[0014] Preferably, the pointed slider has an inclined surface that slopes toward the trough to guide the material particles above and slide them into the trough.

[0015] Preferably, the inner wall shape of the first clamp and the second clamp matches the outer wall contour of the upper flange and the lower flange.

[0016] Preferably, an annular sealing ring is provided on the mating surface of the upper flange and the lower flange to enhance the airtightness of the connection between the devices.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem of cumbersome, time-consuming and labor-intensive installation of the feed inlet device in the prior art by setting a quick locking mechanism consisting of a first clamp, a second clamp, a locking block, a locking groove and a pin, and achieves the effect of quick assembly and disassembly, convenient operation and stable connection.

[0018] 2. This utility model solves the problems of poor dust interception effect of existing dustproof devices and easy accumulation of intercepted materials inside the device by setting baffles inside the dustproof cover and arranging pointed sliders and troughs at the bottom of the baffles. It achieves the effect of effectively blocking dust overflow and automatically clearing accumulated materials by gravity to prevent blockage. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0022] Example: Please refer to Figures 1 to 6 This utility model provides a dustproof device for a feed inlet, which aims to solve the problems of cumbersome installation process, poor dustproof effect, and easy material accumulation inside the feed inlet device in the prior art.

[0023] Please refer to Figure 1 , Figure 4 and Figure 5The bottom end of the feed pipe 1 is fixedly connected to an upper flange 201. The dustproof guide mechanism 3 includes a lower flange 207 and a dust cover 301 fixedly connected to the inner wall of the lower flange 207. The upper flange 201 and the lower flange 207 are detachably engaged through a locking mechanism 2. The locking mechanism 2 includes a first clamp 202 rotatably connected to the rear side of the upper flange 201 and a second clamp 204 rotatably connected to the left end of the first clamp 202. The first clamp 202 and the second clamp 204 are used to clamp the upper flange 201 and the lower flange 207 from the outer wall. The right end of the first clamp 202 is fixedly connected to a locking block 203, and the left end of the second clamp 204 is provided with a slot 205 for engaging with the locking block 203.

[0024] Please refer to Figure 2 , Figure 3 and Figure 5 The locking mechanism 2 also includes a pin 206. The second clamp 204 has a through hole for the pin 206 to be inserted. After the first clamp 202 and the second clamp 204 are closed and the block 203 is fully inserted into the slot 205, the pin 206 passes through the through hole on the second clamp 204 and penetrates downward through the block 203, thereby axially limiting the position of the block 203 and preventing the block 203 from accidentally coming out of the slot 205, thus ensuring the reliability of the connection. The inner wall shape of the first clamp 202 and the second clamp 204 matches the outer wall contour of the upper flange 201 and the lower flange 207, so that they can fit together with the largest area when clamping, providing a stable clamping force. To further improve the sealing performance, an annular sealing ring 208 is provided on the mating surface of the upper flange 201 and the lower flange 207 to enhance the airtight connection between the feed pipe 1 and the dust cover 301.

[0025] Please refer to Figure 4 , Figure 5 and Figure 6 The top of the dust cover 301 is rotatably connected to a guide plate 302. The bottom of the inner wall of the guide plate 302 is fixedly connected to a baffle 303. The bottom of the baffle 303 is provided with a groove 306 around its perimeter. A pointed slider 305 is also fixedly connected to the bottom of the baffle 303. The pointed slider 305 and the groove 306 are arranged in an overlapping manner along the bottom circumference of the baffle 303. This staggered structure can effectively prevent materials from accumulating on the baffle 303.

[0026] In a preferred embodiment, to prevent the locking mechanism 2 from accidentally coming loose under vibration or external impact, thereby improving the reliability and safety of the connection, the locking mechanism 2 also includes a pin 206. The second clamp 204 has a through hole for the pin 206 to be inserted. After the block 203 is engaged with the slot 205, the pin 206 is inserted into the through hole on the second clamp 204 and passes through the block 203 downward, thereby axially limiting the block 203 and preventing the block 203 from accidentally coming out of the slot 205.

[0027] As another preferred embodiment, in order to further optimize the dustproof and flow guiding mechanism 3 for collecting and guiding material particles, a curved ring plate 304 is fixedly connected to the inner wall of the baffle 303. The curved ring plate 304 can form a buffer area when the baffle 303 intercepts material particles.

[0028] As another preferred embodiment, in order to clarify the specific structural function of the bending ring plate 304, the inner wall of the bending ring plate 304 and the baffle 303 together form a buffer cavity for receiving and buffering falling material particles. Particles blocked by the baffle 303 will enter this buffer cavity, thereby slowing down the speed of the particles and avoiding secondary dust or rebound caused by direct impact.

[0029] As another preferred embodiment, in order to ensure that the material particles intercepted by the baffle 303 can flow back smoothly, the pointed slider 305 and the trough 306 are arranged in an overlapping manner along the bottom circumference of the baffle 303. This arrangement ensures that each area at the bottom of the baffle 303 can effectively guide the material and prevent accumulation.

[0030] In another preferred embodiment, in order to further improve the material guiding efficiency and anti-clogging ability, the pointed slider 305 has an inclined surface that slopes toward the trough 306. Once the material particles fall onto the pointed slider 305, they will slide naturally along the inclined surface into the adjacent trough 306 under the action of gravity, thereby avoiding the accumulation of materials above the pointed slider 305.

[0031] In another preferred embodiment, in order to ensure that the locking mechanism 2 can tightly and securely clamp the upper flange 201 and the lower flange 207, the inner wall shape of the first clamp 202 and the second clamp 204 matches the outer wall contour of the upper flange 201 and the lower flange 207. This matching shape design can maximize the contact area between the clamps and the flange, provide uniform clamping force, and enhance the stability of the connection.

[0032] As another preferred embodiment, in order to effectively improve the sealing performance of the entire device, especially when dealing with fine dust, and to prevent dust from escaping from the connection gap, an annular sealing ring 208 is provided on the mating surface of the upper flange 201 and the lower flange 207. The annular sealing ring 208 is compressed when the flanges are mated, filling the tiny gaps and achieving an airtight connection.

[0033] Working principle: During installation, the upper flange 201 and the lower flange 207 are pressed tightly together. An annular sealing ring 208 is provided on the mating surface of the upper flange 201 and the lower flange 207 to enhance airtightness. Then, the first clamp 202 and the second clamp 204 are rotated inward to match the inner wall shape of the first clamp 202 and the second clamp 204 with the outer wall contour of the upper flange 201 and the lower flange 207 for a tight fit. At the same time, the locking block 203 is inserted into the locking groove 205. Then, the pin 206 is inserted into the second clamp 204 and passes downward through the locking block 203 to prevent the locking block 203 from coming out of the locking groove 205, thereby achieving fast and reliable installation. When conveying materials, the materials fall from the feed pipe 1. The material particles in the middle will pass through the dust cover 301, while the material particles that are scattered outward will be guided by the guide plate 302 and effectively blocked by the baffle 303. The blocked material particles fall into the buffer chamber formed by the curved ring plate 304. Some of the material particles in the buffer chamber will slide down along the trough 306, and the other part will fall on the pointed slider 305 and slide down along the inclined surface of the pointed slider 305 into the trough 306. Finally, all of them will fall into the equipment below. Through the synergistic effect of the baffle 303, the trough 306 and the pointed slider 305, this utility model solves the problems of dust overflow and easy material accumulation in the prior art.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
