Abstract
Description
Technical Field
[0001] This utility model belongs to the field of diatomaceous earth raw soil screening technology, and in particular relates to a screening and processing device for diatomaceous earth raw soil. Background Technology
[0002] In the field of diatomaceous earth raw soil screening and processing equipment, the sieve drum screener is a common and important piece of equipment. The sieve drum screener is mainly composed of a machine body, a sieve drum, and other components. Its working principle is to use the rotation of the sieve drum to make the diatomaceous earth raw soil continuously roll and move inside the sieve drum. Diatomaceous earth that meets the sieve hole size falls through the sieve hole, thereby achieving the screening purpose. In actual production, the sieve drum screener is widely used in the diatomaceous earth raw soil screening process because of its relatively simple structure, convenient operation, and ability to operate continuously.
[0003] The problem with the existing technology is that when the existing screen cylinder screening machine is in use, due to the stickiness of diatomaceous earth and the presence of unscreened impurities, it is easy for these impurities to adhere to the screen holes during the screening process, causing some screen holes to become blocked. This not only reduces screening efficiency and slows down the production speed, but also requires frequent manual shutdowns to clean the screen holes, increasing the labor intensity. Utility Model Content
[0004] To address the problems existing in the prior art, this utility model provides a screening and processing device for diatomaceous earth raw materials. It has the advantages of automatic cleaning of screen holes, improved screening efficiency, and reduced labor intensity. To a certain extent, it improves or solves the problem that when existing screen cylinder screening machines are used, diatomaceous earth has a certain degree of stickiness and contains unscreened impurities, which easily adhere to the screen holes during the screening process, causing some screen holes to become blocked. This not only reduces screening efficiency and significantly slows down the production speed, but also requires frequent manual shutdowns to clean the screen holes, increasing labor intensity.
[0005] This utility model is implemented as follows: a screening and processing device for diatomaceous earth raw soil includes a body, a screen cylinder, and screen holes. The screen cylinder is located at the upper end of the body and is movably connected to the body. The number of screen holes is several and they are evenly distributed around the circumference of the screen cylinder. Several vibration components are evenly distributed around the circumference of the front and rear ends of the screen cylinder. Extrusion components are respectively provided on the front and rear sides of the upper right side of the body. Both extrusion components are fixedly connected to the body. A cleaning component is provided inside the upper end of the screen cylinder.
[0006] The preferred vibrating assembly of this utility model includes a rotating seat, a beater, and a tension spring. The rotating seat is fixedly connected to the front side of the upper surface of the screen cylinder. The front end of the beater is sleeved on the surface of the rotating seat and rotatably connected to the rotating seat. The tension spring is fixedly connected to the rear end of the lower surface of the beater, and the lower end of the tension spring is fixedly connected to the upper surface of the screen cylinder. By setting the vibrating assembly, the screen cylinder surface is struck. The instantaneous vibration generated by the striking the screen cylinder surface dislodges some of the diatomaceous earth adhering and clogging the screen holes. This avoids a large amount of clogging of the screen holes, effectively improves screening efficiency, effectively reduces the need for frequent manual shutdowns to clean the screen holes, reduces labor intensity, and improves overall production efficiency.
[0007] In a preferred embodiment of this invention, a plurality of rubber protrusions are uniformly fixedly connected to the lower surface of the clapper. The lower side of the rubber protrusions contacts the surface of the sieve cylinder. By uniformly fixing a plurality of rubber protrusions to the lower surface of the clapper and having them in contact with the surface of the sieve cylinder, the clapper can directly contact and strike the surface of the sieve cylinder, thus avoiding hard damage to the surface of the sieve cylinder caused by the clapper and effectively reducing the noise generated by the striking.
[0008] The preferred extrusion component of this utility model includes a fixed base and an extrusion block. The fixed base is fixedly connected to the front end of the upper right surface of the machine body, and the extrusion block is fixedly connected to the upper end of the fixed base. The position of the extrusion block corresponds to and is adapted to the position of the front end of the clapper. By setting the extrusion component, the clapper is tilted up by the extrusion block and the clapper and then rebounded by the tension spring to strike the screen cylinder. When the screen cylinder vibrates and screens, it drives multiple clappers to sequentially extrude and cooperate with the protrusion.
[0009] The preferred cleaning assembly of this utility model includes a fixing plate and a brush strip. The fixing plate is disposed at the upper end of the inside of the screen cylinder, and extends out of the screen cylinder at both the front and rear ends. The brush strip is fixedly connected to the upper surface of the fixing plate. By setting the cleaning assembly, the screen cylinder rotates during screening to clean the inner wall of the screen cylinder and the screen holes, brushing off the diatomaceous earth adhering and clogging the inner wall of the screen cylinder and the screen holes, and cooperating with the vibration assembly for cleaning and anti-clogging.
[0010] As a preferred embodiment of this utility model, the lower sides of the front and rear ends of the fixed plate are respectively fixedly connected to support frames. The lower right sides of the two support frames are fixedly connected to the upper right side of the machine body. By fixing the support frames to the lower sides of the front and rear ends of the fixed plate, the cleaning component is supported and fixed, ensuring the stability of the cleaning component during screening in the screen cylinder, so that it can continuously and reliably clean the inner wall of the screen cylinder and the screen holes.
[0011] In this invention, the upper side of the brush strip is in contact with the inner wall of the sieve cylinder. By setting the upper side of the brush strip in contact with the inner wall of the sieve cylinder and squeezing it to a certain extent, it can fit more tightly against the inner wall of the sieve cylinder, enhance the cleaning effect, and effectively clean the diatomaceous earth on the inner wall of the sieve cylinder and deep inside the sieve holes.
[0012] 1. This utility model, through the coordinated use of a machine body, screen cylinder, screen holes, vibrating assembly, rotating seat, clapper, tension spring, extrusion component, fixed seat, extrusion block, cleaning assembly, fixed plate, brush strip, rubber protrusion, and support frame, improves or solves to a certain extent the problem of existing screen cylinder screening machines where, due to the stickiness of diatomaceous earth and the presence of unscreened impurities, diatomaceous earth easily adheres to the screen holes during the screening process, causing blockage of some screen holes. This not only reduces screening efficiency and significantly slows down production speed, but also requires frequent manual shutdowns to clean the screen holes, increasing labor intensity.

[0018] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0019] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0020] like Figures 1 to 4As shown in the figure, the diatomaceous earth raw soil screening and processing equipment provided by this utility model embodiment includes a body 1, a screen cylinder 2 and screen holes 3. The screen cylinder 2 is set at the upper end of the body 1 and is movably connected to the body 1. The number of screen holes 3 is several and they are evenly opened on the circumference of the screen cylinder 2. Several vibration components 4 are evenly arranged on the circumference of the front and rear ends of the screen cylinder 2. Extrusion components 5 are respectively arranged on the front and rear sides of the upper right side of the body 1. Both extrusion components 5 are fixedly connected to the body 1. A cleaning component 6 is arranged at the upper end of the inside of the screen cylinder 2.
[0021] refer to Figure 1 and Figure 2 The vibration assembly 4 includes a rotating seat 41, a clapper 42, and a tension spring 43. The rotating seat 41 is fixedly connected to the front side of the upper surface of the screen cylinder 2. The front end of the clapper 42 is sleeved on the surface of the rotating seat 41 and is rotatably connected to the rotating seat 41. The tension spring 43 is fixedly connected to the rear end of the lower surface of the clapper 42, and the lower end of the tension spring 43 is fixedly connected to the upper surface of the screen cylinder 2.
[0022] The above solution involves setting up a vibration component 4 to strike the surface of the screen cylinder 2. The instantaneous vibration generated by striking the surface of the screen cylinder 2 dislodges some of the diatomaceous earth that is attached and clogging the screen holes 3. This avoids a large amount of clogging in the screen holes 3, effectively improves screening efficiency, reduces the need for frequent manual shutdowns to clean the screen holes 3, lowers labor intensity, and improves overall production efficiency.
[0023] refer to Figure 1 and Figure 2 Several rubber protrusions 7 are evenly fixedly connected to the lower surface of the clapper 42, and the lower side of the rubber protrusions 7 is in contact with the surface of the screen cylinder 2.
[0024] The above solution involves uniformly fixing several rubber protrusions 7 to the lower surface of the clapper 42, which are in contact with the surface of the sieve cylinder 2. This allows for direct contact and impact with the surface of the sieve cylinder 2, preventing hard damage to the surface of the sieve cylinder 2 caused by the clapper 42 and effectively reducing the noise generated by the impact.
[0025] refer to Figure 1 , Figure 2 and Figure 3 The extrusion component 5 includes a fixed base 51 and an extrusion block 52. The fixed base 51 is fixedly connected to the front end of the upper right side surface of the machine body 1, and the extrusion block 52 is fixedly connected to the upper end of the fixed base 51. The position of the extrusion block 52 corresponds to and is adapted to the position of the front end of the clapper 42.
[0026] The above scheme is adopted: by setting up the extrusion member 5, the extrusion block 52 and the clapper 42 are squeezed together to make the clapper 42 tilt up and then be rebounded by the tension spring 43 to strike the screen cylinder 2. When the screen cylinder 2 vibrates and screens, it drives multiple clappers 42 to squeeze together with the protrusion in sequence.
[0027] refer to Figure 1 and Figure 4 The cleaning assembly 6 includes a fixing plate 61 and a brush strip 62. The fixing plate 61 is located inside the upper part of the screen cylinder 2, and extends out of the screen cylinder 2 at both the front and rear ends. The brush strip 62 is fixedly connected to the upper surface of the fixing plate 61.
[0028] The above solution is adopted: by setting up a cleaning component 6, the inner wall of the screen cylinder 2 and the screen holes 3 are cleaned by the rotation of the screen cylinder 2 during screening, so as to brush off the diatomaceous earth adhering and clogging on the inner wall of the screen cylinder 2 and the screen holes 3, and in conjunction with the vibration component 4, cleaning and anti-clogging are carried out.
[0029] refer to Figure 1 and Figure 4 Support frames 8 are fixedly connected to the lower sides of the front and rear ends of the fixed plate 61, and the lower right side of the two support frames 8 is fixedly connected to the upper right side of the body 1.
[0030] The above solution is adopted: support frames 8 are fixedly connected to the lower sides of the front and rear ends of the fixed plate 61 to support and fix the cleaning component 6, thereby ensuring the stability of the cleaning component 6 during screening in the screen cylinder 2, so that it can continuously and reliably clean the inner wall of the screen cylinder 2 and the screen holes 3.
[0031] refer to Figure 1 and Figure 4 The upper side of the brush strip 62 contacts the inner wall of the screen cylinder 2.
[0032] By adopting the above solution, the brush strip 62 is positioned to contact the inner wall of the screen cylinder 2 and is squeezed to a certain extent, which can make it fit more tightly against the inner wall of the screen cylinder 2, enhance the cleaning effect, and effectively clean the diatomaceous earth on the inner wall of the screen cylinder 2 and inside the screen hole 3.
[0033] In use, when the screen cylinder 2 rotates, the vibrating component 4 on the screen cylinder 2 rotates accordingly. The front end of the beater 42 is sleeved on the rotating seat 41 and can rotate freely. The rear end is connected to the upper surface of the screen cylinder 2 through the tension spring 43. When the beater 42 rotates to correspond to the position of the extrusion block 52 of the extruder 5, as the screen cylinder 2 rotates, the front end of the beater 42 gradually approaches the extrusion block 52. After the two come into contact, the extrusion block 52 applies extrusion force to the beater 42, causing the beater 42 to tilt upwards. During the tilting process of the beater 42, the tension spring 43 is further stretched and stores elastic potential energy. When the front end of the beater 42 passes the extrusion block 52, it loses the extrusion force. At this time, the tension spring 43 releases elastic potential energy, causing the rear end of the beater 42 to rebound rapidly. The rubber protrusions on the lower surface of the beater 42... 7. The screen cylinder 2 is struck heavily, generating vibration and dislodging the diatomaceous earth clogged inside the screen holes 3. As the screen cylinder 2 continues to rotate, the clappers 42 of the multiple vibration components 4 will sequentially press and cooperate with the extrusion block 52 to achieve continuous striking and vibration on the surface of the screen cylinder 2. The fixing plate 61 of the cleaning component 6 is fixed to the machine body 1 by the support frame 8 on the lower side of the front and rear ends to ensure its stability. The brush strip 62 is fixed to the upper surface of the fixing plate 61 and contacts the inner wall of the screen cylinder 2 and maintains a certain pressure. During the rotation of the screen cylinder 2, the inner wall of the screen cylinder 2 and the brush strip 62 generate relative movement. The brush strip 62 cleans the inner wall of the screen cylinder 2 and the screen holes 3, brushing off the diatomaceous earth attached to it. It works with the vibration component 4 to clean the screen holes 3 and prevent clogging.
[0034] In summary, this diatomaceous earth raw material screening and processing equipment, through the coordinated use of the machine body 1, screen cylinder 2, screen holes 3, vibration component 4, rotating seat 41, clapper 42, tension spring 43, extrusion component 5, fixed seat 51, extrusion block 52, cleaning component 6, fixed plate 61, brush strip 62, rubber protrusion 7, and support frame 8, improves or solves to a certain extent the problem of existing screen cylinder screening machines where, due to the stickiness of diatomaceous earth and the presence of unscreened impurities, diatomaceous earth easily adheres to the screen holes during screening, causing blockage of some screen holes. This not only reduces screening efficiency and significantly slows down production speed, but also requires frequent manual shutdowns to clean the screen holes, increasing labor intensity.
