Description

Technical Field

[0001] This utility model relates to the field of mineral processing equipment technology, specifically a self-cleaning screen plate. Background Technology

[0002] Mineral processing screens are key components used for material classification and screening in the mineral processing process. They are usually installed on equipment such as vibrating screens and drum screens. Their core function is to separate materials based on differences in particle size, thereby improving the grade of the ore or meeting the requirements of subsequent processing.

[0003] When using screen plates for mineral processing, sticky materials (ores with high mud content and wet coal) tend to adhere to the screen holes, resulting in a reduction in effective screening area, a decrease in throughput, and a drop in screening efficiency. After the holes are blocked, the accumulation of material increases the load on the screen plate, accelerates wear, or causes the screen plate to deform or break. The current solution is to manually clean the blocked holes. Manual cleaning not only requires frequent machine shutdowns but is also time-consuming and inefficient, affecting production efficiency. Therefore, we propose a self-cleaning screen plate. Utility Model Content

[0004] The purpose of this invention is to provide a self-cleaning screen plate to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning sieve plate, including a sieve plate base frame, a sieve plate body is provided inside the sieve plate base frame, and sieve holes are provided inside the sieve plate body. A sealing area is provided on the surface of the sieve plate body. A support rod is fixed inside the sieve plate base frame below the sieve plate body, and a limiting sleeve is fixed inside the support rod. An opening groove is provided at the bottom of the sieve plate base frame. A push rod is provided inside the limiting sleeve, and the top end of the push rod extends above the limiting sleeve and is fixed with a cleaning push head. A cleaning mechanism is provided inside the opening groove. The cleaning mechanism corresponds one-to-one with the sealing area. The cleaning mechanism includes a support base, a small motor, a rotating rod, a rotating wheel, and a crank. The support base is fixed at the bottom end of the sieve plate base frame. The small motor is installed on the outer wall of the support base. The rotating rod is located on one side of the support base. One end of the rotating rod is fixedly connected to the output end of the support base. The rotating wheel is fixed to the other end of the rotating rod. The crank is installed on one side of the rotating wheel through a first rotating shaft. The crank is connected to the push rod through a second rotating shaft.

[0006] Preferably, a positioning groove is provided on the inner wall of the top of the sieve plate base frame, and the edge of the sieve plate body extends into the interior of the positioning groove and is glued and fixed to the sieve plate base frame, so as to facilitate fixing the sieve plate body inside the sieve plate base frame.

[0007] Preferably, there are four sealing areas distributed at the corners of the screen plate body surface, so that the pushing force of the cleaning pusher is evenly applied to the screen plate body.

[0008] Preferably, the cleaning pusher has a hemispherical structure, and the surface of the cleaning pusher is adhered with a rubber layer to facilitate the cleaning pusher to fit with the screen plate body.

[0009] Preferably, the inner wall of the limiting sleeve is provided with equally spaced roller grooves, and the inside of the roller grooves is provided with balls, which contact the push rod. During the up and down movement of the push rod, the balls roll and contact the push rod, thereby reducing the frictional resistance between the push rod and the limiting sleeve. This not only makes the reciprocating movement of the push rod and the cleaning push head smoother, but also reduces the wear of the push rod and the limiting sleeve, and extends the service life.

[0010] Preferably, a rod sleeve is fixed to one side of the support base, and the rotating rod passes through the rod sleeve and is connected to the rod sleeve through a bearing.

[0011] Preferably, the small motor is provided with a protective shell, and one end of the protective shell is fixedly connected to the support base.

[0012] Preferably, the sieve plate body is made of deformable rubber material, which makes the sieve plate body elastic and deformable.

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

[0014] When using the screen plate body for mineral processing, a small motor drives the rotating rod to rotate, which in turn drives the rotating wheel to rotate. During the rotation of the rotating wheel, the rotating wheel drives the push rod to move up and down inside the limiting sleeve via a crank. The push rod drives the cleaning push head to move up and down reciprocally. Since the screen plate body is made of deformable rubber material, the push rod continuously lifts the sealing area of ​​the screen plate body. Utilizing the elastic deformation of the screen plate material, the screen holes periodically open and close under the action of lifting and deformation, causing the hole diameter to change and discharging the stuck particles, thus achieving a self-cleaning function. It is suitable for ores and wet coal with high mud content, which can greatly reduce their adhesion to the screen holes, reduce clogging, and thus improve the throughput and screening efficiency. Moreover, it does not require machine downtime, improving production efficiency. 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 of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 The present invention provides an embodiment of a self-cleaning sieve plate, comprising a sieve plate base frame 1, a sieve plate body 2 disposed inside the sieve plate base frame 1, and a sieve hole 3 disposed inside the sieve plate body 2, a sealing area 4 disposed on the surface of the sieve plate body 2, a support rod 6 fixed inside the sieve plate base frame 1 below the sieve plate body 2, and a limiting sleeve 7 fixed inside the support rod 6, an opening groove 8 disposed at the bottom of the sieve plate base frame 1, a push rod 19 disposed inside the limiting sleeve 7, and a cleaning push head 20 fixed at the top end of the push rod 19 extending above the limiting sleeve 7;

[0023] The opening groove 8 is equipped with a cleaning mechanism 9, which corresponds one-to-one with the sealing area 4. The cleaning mechanism 9 includes a support base 10, a small motor 11, a rotating rod 14, a rotating wheel 15, and a crank 17. The support base 10 is fixed to the bottom end of the screen plate base frame 1. The small motor 11 is installed on the outer wall of the support base 10. The rotating rod 14 is located on one side of the support base 10. One end of the rotating rod 14 is fixedly connected to the output end of the support base 10. The rotating wheel 15 is fixed to the other end of the rotating rod 14. The crank 17 is installed on one side of the rotating wheel 15 through the first rotating shaft 16. The crank 17 is connected to the push rod 19 through the second rotating shaft 18.

[0024] Specifically, when using the screen plate body 2 for mineral processing, the small motor 11 drives the rotating rod 14 to rotate, and the rotating rod 14 drives the rotating wheel 15 to rotate. During the rotation of the rotating wheel 15, the rotating wheel 15 drives the push rod 19 to move up and down inside the limiting sleeve 7 through the crank 17. The push rod 19 drives the cleaning push head 20 to move up and down reciprocally. Since the screen plate body 2 is made of deformable rubber material, the push rod 19 continuously lifts the sealing area 4 of the screen plate body 2.

[0025] By utilizing the elastic deformation of the screen plate material, the screen holes 3 periodically open and close under the action of supporting deformation, causing the aperture to change and expelling stuck particles, thus achieving a self-cleaning function. It is suitable for ores and wet coal with high mud content, which can greatly reduce their adhesion to the screen holes 3, reduce clogging, and thus improve the throughput and screening efficiency. Moreover, it does not require machine shutdown, thus improving production efficiency.

[0026] A positioning groove 5 is provided on the inner wall of the top of the sieve plate base frame 1, and the edge of the sieve plate body 2 extends into the interior of the positioning groove 5 and is glued and fixed to the sieve plate base frame 1.

[0027] There are four sealing zones 4, which are located at the corners of the surface of the sieve plate body 2.

[0028] The cleaning pusher head 20 has a hemispherical structure, and a rubber layer 21 is adhered to the surface of the cleaning pusher head 20;

[0029] The inner wall of the limiting sleeve 7 is provided with equally spaced roller grooves 22, and the inside of the roller grooves 22 is provided with balls 23, and the balls 23 are in contact with the push rod 19.

[0030] Specifically, since the inner wall of the limiting sleeve 7 is provided with a roller groove 22 and the inside of the roller groove 22 is provided with a ball 23, during the up and down movement of the push rod 19, the ball 23 rolls and contacts it, thereby reducing the frictional resistance between the push rod 19 and the limiting sleeve 7. This not only makes the reciprocating motion of the push rod 19 and the cleaning push head 20 smoother, but also reduces the wear of the push rod 19 and the limiting sleeve 7, and extends the service life.

[0031] A rod sleeve 13 is fixed on one side of the support base 10, and a rotating rod 14 passes through the rod sleeve 13 and is connected to the rod sleeve 13 through a bearing;

[0032] The small motor 11 is provided with a protective shell 12, and one end of the protective shell 12 is fixedly connected to the support base 10, which can protect the small motor 11.

[0033] The sieve plate body 2 is made of deformable rubber material.

[0034] In this embodiment of the application, when using the screen plate body 2 for mineral processing, the small motor 11 drives the rotating rod 14 to rotate, and the rotating rod 14 drives the rotating wheel 15 to rotate. During the rotation of the rotating wheel 15, the rotating wheel 15 drives the push rod 19 to move up and down inside the limiting sleeve 7 through the crank 17. The push rod 19 drives the cleaning push head 20 to move up and down reciprocally. Since the screen plate body 2 is made of deformable rubber material, the push rod 19 continuously lifts the sealing area 4 of the screen plate body 2. Utilizing the elastic deformation of the screen plate material, under the action of lifting and deformation, the screen holes 3 periodically open and close, causing the hole diameter to change, thereby discharging the stuck particles and achieving [the desired effect]. It features a self-cleaning function, making it suitable for ores and wet coal with high mud content. It can greatly reduce the adhesion of mud to the screen holes 3, reduce clogging, and thus improve the throughput and screening efficiency. Moreover, it does not require machine downtime, improving production efficiency. Furthermore, since the inner wall of the limiting sleeve 7 is provided with a roller groove 22, and the inside of the roller groove 22 is provided with a ball bearing 23, the ball bearing 23 rolls and contacts the push rod 19 during its up and down movement, thereby reducing the frictional resistance between the push rod 19 and the limiting sleeve 7. This not only makes the reciprocating motion of the push rod 19 and the cleaning push head 20 smoother, but also reduces the wear of the push rod 19 and the limiting sleeve 7, extending their service life.
