Raw material screening device for high-temperature resistant special ceramics production

Abstract

This utility model discloses a raw material screening device for the production of high-temperature resistant special ceramics, relating to the field of raw material screening technology. The utility model includes a vibrating base, a screen cylinder, and a screen mesh, as well as a supporting screen plate, a support frame, a limiting adjustment component, and an elastic ball. The utility model uses a limiting disc that slides from top to bottom through the interior of a sliding groove. During sliding, the disc contacts the end of a sliding plate, pushing two sets of sliding plates in opposite directions. This causes the clamping plate to contact the inner wall of the flow hole in the supporting screen plate, thus fixing the positioning insert to the surface of the supporting screen plate. Tightening the positioning bolt allows it to pass through the positioning hole, limiting and fixing the positioning rod, thereby fixing the supporting insert to the surface of the positioning insert. This allows for adjusting the installation height of the limiting disc while simultaneously limiting and fixing the positioning insert, accelerating the installation efficiency of the limiting adjustment component. The conical surface of the limiting disc restricts the movement of the elastic ball within its range during vibration.

Description

Technical Field

[0001] This utility model relates to the field of raw material screening technology, specifically to a raw material screening device for the production of high-temperature resistant special ceramics. Background Technology

[0002] In the production of high-temperature resistant special ceramics, raw material screening is one of the key pretreatment processes. Currently, most common screening devices adopt a circular vibrating screen structure. To ensure more sufficient vibration at the suspended part of the screen, elastic balls are placed below the screen and pressed against it. To ensure that the material slides to the sides and is finally discharged through the discharge port of the screen cylinder, the screen is often set so that the center is higher than the edge.

[0003] However, since the elastic balls can move freely under the screen, as the vibration continues, the elastic balls will tend to gather towards the center of the screen where the pressure is less, resulting in uneven distribution of the elastic balls and affecting the screening efficiency of the screen. Furthermore, due to the inclined surface of the screen, the size of the elastic balls placed closer to the edge needs to be gradually reduced, which is inconvenient to use. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a raw material screening device for the production of high-temperature resistant special ceramics, which solves the problem of uneven distribution caused by the movement and displacement of the elastic balls below the screen.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: a raw material screening device for the production of high-temperature resistant special ceramics, including a vibrating base, a screen cylinder and a screen mesh, and further including a support screen plate, a support frame, a limiting adjustment component and an elastic ball. The screen cylinder is disposed on the top of the vibrating base, the screen mesh is fixedly installed inside the screen cylinder, the support screen plate is fixedly installed inside the screen cylinder, and the support frame is fixedly installed inside the screen cylinder, with the support frame located between the screen mesh and the support screen plate and fitting against both. The limiting adjustment component consists of a support plug and a positioning plug. The positioning plug is slidably installed on the surface of the support mesh plate. The support plug passes through the positioning plug in the vertical direction. The elastic ball is placed on the top of the support plug and is in contact with the screen.

[0006] The surface of the support mesh plate has multiple sets of arrayed flow holes.

[0007] The support frame consists of an annular plate and a rectangular plate. The rectangular plate is fixedly installed around the annular plate, and the horizontal top surface of the annular plate and the inclined top surface of the rectangular plate are in contact with the bottom surface of the screen.

[0008] The support insert of the limiting adjustment component includes a limiting plate, a positioning rod, and positioning holes. The positioning rod is fixedly installed at the bottom of the limiting plate. The surface of the positioning rod has multiple positioning holes that penetrate horizontally and are arranged at equal intervals.

[0009] The limiting plate is cone-shaped, and the elastic ball is placed at the lowest point of the recess of the limiting plate. Multiple sets of circular array flow grooves are opened on the surface of the limiting plate.

[0010] The positioning insert of the limiting adjustment component includes a fixing block, a sliding groove, a connecting plate, and a positioning bolt. The fixing block is slidably installed on the surface of the supporting mesh plate. The surface of the fixing block is provided with a sliding groove. The connecting plates are fixedly installed at the bottom of the fixing block. There are two sets of them, which are symmetrically arranged. The positioning bolt is slidably inserted into one set of connecting plates and threadedly connected to the other set of connecting plates.

[0011] The positioning plug of the limiting adjustment component also includes a card plate and a sliding plate. The sliding plate is fixedly installed on the side of the card plate near the fixing block. The card plate is attached to the surface of the supporting mesh plate. There are two sets of card plates and sliding plates, which are symmetrically arranged about the fixing block.

[0012] The chute consists of a first through groove in the vertical direction and a second through groove in the horizontal direction, and the two are connected.

[0013] The beneficial effects of this utility model are as follows: This invention uses a limiting disc that slides through the interior of a groove from top to bottom. During sliding, it contacts the end of a sliding plate, pushing two sets of sliding plates to slide in opposite directions. This causes the clamping plate to contact the inner wall of the flow hole in the support mesh plate, thus fixing the positioning plug onto the surface of the support mesh plate. Tightening the positioning bolt allows it to pass through the positioning hole, limiting and fixing the positioning rod, thereby fixing the support plug onto the surface of the positioning plug. This allows for adjusting the installation height of the limiting disc while simultaneously limiting and fixing the positioning plug, accelerating the installation efficiency of the limiting adjustment component. The conical surface of the limiting disc restricts the movement of the elastic balls within its range during vibration, preventing the elastic balls from being biased towards the center of the screen due to the inclined surface of the screen. As the vibration progresses, the elastic balls continuously move closer to the center, causing the extra elastic force exerted by the elastic balls on the suspended part of the screen to be mainly concentrated at the center of the screen, which is not evenly distributed. Furthermore, the height-adjustable limiting disc facilitates the batch use of elastic balls of the same size, ensuring that they all fit the bottom of the inclined surface of the screen.

[0016] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0017] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 - Appendix Figure 5 The present invention will be further described below.

[0018] A raw material screening device for the production of high-temperature resistant special ceramics includes a vibrating base 1, a screen cylinder 2, and a screen 3. It also includes a supporting screen plate 4, a support frame 5, a limiting adjustment component 6, and an elastic ball 7. The screen cylinder 2 is located on top of the vibrating base 1. The screen 3 is fixedly installed inside the screen cylinder 2. The supporting screen plate 4 is fixedly installed inside the screen cylinder 2. The support frame 5 is fixedly installed inside the screen cylinder 2 and is located between the screen 3 and the supporting screen plate 4, and is in contact with both. The limiting adjustment component 6 consists of a supporting insert and a positioning insert. The positioning insert is slidably installed on the surface of the supporting screen plate 4. The supporting insert passes through the positioning insert in the vertical direction. The elastic ball 7 is placed on top of the supporting insert and is in contact with the screen 3. Specifically, the vibrating base 1 drives the screen cylinder 2 and its internal components to vibrate continuously. The ceramic raw materials are screened through the screen mesh 3, causing large particles to remain at the top of the screen mesh 3 and be discharged from the discharge port of the screen cylinder 2. Small particles pass through the screen mesh 3 and fall down. The support plate 4 provides support for the limiting adjustment component 6 and the elastic ball 7. The support frame 5 lifts the bottom of the screen mesh 3, making the screen mesh 3 form an inclined surface to facilitate the flow of materials. The limiting adjustment component 6 restricts the range of motion of the elastic ball 7, and the elastic ball 7 increases the vibration effect at the suspended part of the screen mesh 3.

[0019] Multiple sets of flow holes are arranged in an array on the surface of the support mesh plate 4. Specifically, the flow holes ensure that the material can freely pass through the surface of the support mesh plate 4 when it falls.

[0020] The support frame 5 consists of an annular plate and a rectangular plate. The rectangular plate is fixedly installed around the annular plate, and the horizontal top surface of the annular plate and the inclined top surface of the rectangular plate are in contact with the bottom surface of the screen 3. Specifically, the annular plate supports the center of the screen 3, and the rectangular plate supports the area outside the center of the screen 3, forming an inclined plane. This causes the material falling to the top of the screen 3 to slide radially along the screen 3 during the screening process due to the vibration of the device, making the material more dispersed and ensuring screening efficiency.

[0021] The support plug of the limit adjustment component 6 includes a limit plate 601, a positioning rod 602 and a positioning hole 603. The positioning rod 602 is fixedly installed on the bottom of the limit plate 601. The surface of the positioning rod 602 is provided with positioning holes 603 that pass through in the horizontal direction. There are multiple sets of these holes, which are arranged at equal intervals. Specifically, the limiting plate 601 supports the placement of the elastic ball 7 and serves as a limiting function. The positioning rod 602 passes through the slide groove 605 to install the support plug onto the surface of the positioning plug. Multiple sets of positioning holes 603 facilitate the adjustment of the distance between the limiting plate 601 and the fixing block 604.

[0022] The limiting plate 601 is cone-shaped, and the elastic ball 7 is placed at the lowest point of the recess of the limiting plate 601. Multiple sets of circular array flow grooves are opened on the surface of the limiting plate 601. Specifically, the cone shape of the limiting plate 601 causes the elastic ball 7 to move near the lowest point of the recess of the limiting plate 601 during the vibration of the device, thus limiting its range of movement. The flow channel ensures that the material can freely pass through the surface of the limiting plate 601 when it falls.

[0023] The positioning insert of the limit adjustment component 6 includes a fixing block 604, a sliding groove 605, a connecting plate 606, and a positioning bolt 607. The fixing block 604 is slidably installed in the flow hole of the support mesh plate 4. The surface of the fixing block 604 is provided with a sliding groove 605. The connecting plate 606 is fixedly installed at the bottom of the fixing block 604. There are two sets of them, which are symmetrically arranged. The positioning bolt 607 is slidably inserted into one set of connecting plates 606 and threadedly connected to the other set of connecting plates 606. The positioning bolt 607 is correspondingly arranged with the positioning hole 603. Specifically, the movement of the positioning rod 602 and the sliding plate 609 is guided by the slide groove 605, and the support plug is fixed on the surface of the positioning plug by the cooperation of the connecting plate 606 and the positioning bolt 607, and by the positioning bolt 607 passing through the positioning hole 603.

[0024] The positioning plug of the limit adjustment component 6 also includes a clamping plate 608 and a sliding plate 609. The sliding plate 609 is fixedly installed on the side of the clamping plate 608 near the fixing block 604. The clamping plate 608 fits against the inner wall of the flow hole of the support mesh plate 4. There are two sets of clamping plates 608 and sliding plates 609, which are symmetrically arranged about the fixing block 604. Specifically, the positioning plug is fixed inside the support mesh plate 4 by fitting two sets of card plates 608 against the inner walls on both sides of the flow hole.

[0025] The slide 605 consists of a first through groove in the vertical direction and a second through groove in the horizontal direction, which are connected. The positioning rod 602 is corresponding to the first through groove, and the sliding plate 609 is corresponding to the second through groove. Specifically, the positioning rod 602 slides inside the first through groove and contacts the two sets of sliding plates 609, thereby pushing the two sets of sliding plates 609 to move in opposite directions, causing the card plate 608 to move and fit against the inner wall of the flow hole of the support mesh plate 4.

[0026] In summary: When using this utility model, the operator selects the appropriate number of limiting adjustment parts 6 and elastic balls 7 according to the size of the suspended area of ​​the screen 3, and installs the limiting adjustment parts 6 in a suitable position so that the elastic balls 7 are evenly distributed below the screen 3. When installing the limiting adjustment parts 6, first, the fixing block 604 is placed into the flow hole of the supporting screen plate 4, and the positioning rod 602 is inserted from top to bottom into the first through groove of the slide 605. During the downward movement of the positioning rod 602, it contacts the end of the sliding plate 609, pushing the two sets of sliding plates 609 to slide in opposite directions in the second through groove of the slide 605, so that the clamping plate 608 is tightly attached to the inner wall of the flow hole of the supporting screen plate 4, realizing the positioning plug on the surface of the supporting screen plate 4. For rapid fixing of the surface, when the positioning rod 602 passes through the first through groove of the slide 605, the distance between the limiting plate 601 and the fixing block 604 is adjusted according to the installation position of the modified limiting adjustment component 6. The positioning bolt 607 passes through a set of connecting plates 606 and the positioning hole 603. The positioning bolt 607 is rotated to make it threadedly connected to another set of connecting plates 606, thereby realizing the rapid fixing of the support plug on the surface of the positioning plug. The limiting plates 601 of different heights make the elastic balls 7 of different positions but the same size fit against the bottom surface of the screen 3. During the vibration, the elastic force transmission effect of each set of elastic balls 7 on the screen 3 is similar, so that the raw materials for ceramic production are stably screened when passing through its surface.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
