Description

Technical Field

[0001] This utility model belongs to the field of ultrasonic vibrating screen technology, and in particular relates to an ultrasonic vibrating screen that is easy to adjust. Background Technology

[0002] Ultrasonic vibrating screens convert 220V, 50Hz or 110V, 60Hz electrical energy into high-frequency electrical energy (e.g., 38kHz) using an ultrasonic generator. This high-frequency, low-amplitude vibration of the screen mesh is then converted into mechanical vibration by an ultrasonic transducer. This vibration keeps the material on the screen surface in a slightly suspended state, suppressing clogging factors such as adhesion, friction, and agglomeration, thereby improving screening and screen cleaning efficiency. However, it still has the following drawbacks in practical use:

[0003] In the process of ultrasonic vibrating screen screening, the screen body is usually fixed in the vibrating screen. When the screening accuracy requirement of the vibrating screen changes, it is necessary to disassemble the vibrating screen, remove the screen body and replace it to complete the adjustment of the screening accuracy. The adjustment of the screening accuracy of ultrasonic vibrating screen is not convenient.

[0004] Furthermore, the feed end of the ultrasonic vibrating screen needs to be fixedly connected to the equipment or pipeline that conveys the material. During long-term operation, the vibration is directly transmitted to the feed end and the equipment or pipeline that conveys the material. Prolonged operation can easily cause structural fatigue, resulting in breakage at the connection between the feed end and the conveying pipeline. Utility Model Content

[0005] The purpose of this invention is to provide an easily adjustable ultrasonic vibrating screen. By setting up a hopper, screen body and support base, it solves the problems of inconvenient adjustment of the screening accuracy of ultrasonic vibrating screens and the easy damage to the material input position due to long-term vibration.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an easily adjustable ultrasonic vibrating screen, comprising a hopper, a screen body, and a support base. The hopper is inclined, and a sealing plate is fixed to the upward-inclined end of the hopper. A feed pipe is fixedly connected to the top of the hopper near the edge of the sealing plate, and a flexible sleeve is fixedly connected to the top of the feed pipe. A movable opening is formed on one side of the sealing plate along a center line parallel to the long side, and the screen body is movably connected within the movable opening. A connecting plate is fixed to the end of the screen body near the sealing plate, and connecting rods are symmetrically fixed to the sealing plate above the connecting plate. A rotating plate is rotatably connected to the end of the connecting rods away from the sealing plate, and the length of the connecting rods is equal to the thickness of the connecting plate. A support base is provided below the hopper. During operation, the material to be screened is conveyed through the hopper. When the material enters the screen body, it is screened by the screen body during operation. The support base provides inclined support for the hopper.

[0008] Furthermore, movable grooves are provided in the middle of both side walls of the hopper, and the screen body is movably connected in the two movable grooves. The hopper movably supports the screen body through the movable grooves.

[0009] Furthermore, the end of the hopper away from the sealing plate is fixedly connected to two discharge hoppers. The two discharge hoppers are vertically aligned and their output ends are staggered. The top of the screen body is flush with the bottom of the upper discharge hopper, and the bottom of the lower discharge hopper is flush with the bottom of the hopper. The top of the flexible sleeve is fixedly connected to a receiving pipe. The hopper discharges the material through the discharge hopper and transfers the material to be screened to the flexible sleeve through the receiving pipe.

[0010] Furthermore, a handle is fixed in the center of the side of the connecting plate away from the sealing plate, and the end of the screen body away from the connecting plate abuts against the inner wall of the hopper. The connecting plate provides the function of pulling the screen body through the handle.

[0011] Furthermore, the top of the support base is inclined and support legs are fixed at the four corners of the top of the support base. Each support leg is fixed with a support spring at its top. The support base is connected to the support spring through the support leg, and the connecting block is connected to the support leg through the support spring.

[0012] Furthermore, a connecting block is fixed to the top of each of the supporting compression springs, and an ultrasonic vibrator is fixed to the top of each of the connecting blocks. Two connecting blocks are fixed to each side of the hopper, and the connecting blocks generate ultrasonic vibration of the screen body through the ultrasonic vibrator.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of inconvenient adjustment of the screening accuracy of ultrasonic vibrating screens by setting up a hopper and a screen body. After rotating the rotating plate away from the movable opening, hold the handle, support the screen body, align the screen body with the movable opening on the sealing plate, and then insert the screen body into the movable opening on the sealing plate, so that the screen body is inserted into the movable groove on the inner side wall of the hopper until the screen body enters the hopper and is close to the discharge hopper. After it is in contact with the hopper, rotate the rotating plate again so that the rotating plate contacts the connecting plate. After the position between the connecting plate and the sealing plate is determined, the screen body is positioned in the hopper. When it is necessary to replace it, rotate the rotating plate, pull the handle, and pull out the screen body. Then, by selecting a screen body with a suitable screening accuracy, repeat the above installation operation to change the screening accuracy of the ultrasonic vibrating screen, making the adjustment of the screening accuracy of the ultrasonic vibrating screen more convenient.

[0015] This invention solves the problem of material damage at the input position of an ultrasonic vibrating screen caused by prolonged vibration by setting up a hopper, screen body, and support base. After the ultrasonic vibrator generates excitation force, it drives the connecting block to vibrate. The ultrasonic vibration of the connecting block drives the hopper and the screen body within it to vibrate. At the same time, the material is transferred and transported to the flexible sleeve through the receiving pipe, and then to the feed pipe through the flexible sleeve. The material is then transported to the hopper through the feed pipe. The flexible sleeve is connected to the receiving pipe, so the material received in the receiving pipe is transferred to the feed pipe. At the same time, the flexible sleeve is designed to reduce the transmission of vibration from the hopper to the receiving pipe, thereby reducing the impact of vibration on the feeding equipment and making the material at the input position of the ultrasonic vibrating screen less prone to fatigue damage caused by vibration transmission.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0026] Please see Figure 1-6This utility model is an easily adjustable ultrasonic vibrating screen, including a hopper 1, a screen body 2, and a support base 3. The hopper 1 is inclined, and a sealing plate 106 is fixed to the upward inclined end of the hopper 1. The hopper 1 provides space for the material to be screened. The sealing plate 106 closes the upward end of the hopper 1. A feed pipe 103 is fixedly connected to the top of the hopper 1 near the edge of the sealing plate 106. When the feed pipe 103 is working, the material conveyed in the flexible sleeve 104 is transferred to the hopper 1. A flexible sleeve 104 is fixedly connected to the top end of the feed pipe 103, and is connected to the receiving pipe 105 through the flexible sleeve 104, so that the material received in the receiving pipe 105 is transferred to the feed pipe 103. At the same time, the flexible sleeve 104 is flexibly designed to reduce the transmission of vibration of the hopper 1 to the receiving pipe 105, thereby reducing the impact of vibration on the feeding equipment. A movable opening 109 is opened in the center of one side of the sealing plate 106 along the center line parallel to the long side. The sealing plate 106 is movably connected to the screen body 2 through the movable opening 109. A screen body 2 is movably connected inside the movable opening 109. When the screen body 2 is working, the material passing through the hopper 1 is screened under ultrasonic vibration. A connecting plate 201 is fixed to one end of the screen body 2 near the sealing plate 106. The screen body 2 is connected to a handle 202 through the connecting plate 201, allowing the screen body 2 to be pulled out of the hopper 1. Connecting rods 107 are symmetrically fixed to the sealing plate 106 above the connecting plate 201. The rotating plate 108 is connected to the connecting plate 201 through the connecting rods 107. The connecting rods 107 are away from the sealing plate 106. One end of plate 106 is rotatably connected to a rotating plate 108. The length of the connecting rod 107 is equal to the thickness of the connecting plate 201. When the connecting plate 201 moves to contact the sealing plate 106, the screen body 2 is stably set in the hopper 1. By rotating the rotating plate 108, when the rotating plate 108 rotates to contact the connecting plate 201, the connecting plate 201 and the screen body 2 are restricted in the hopper 1. A support base 3 is provided below the hopper 1. When the support base 3 is working, the hopper 1 is tilted and supported on the working plane.

[0027] Specifically, movable grooves 101 are provided in the middle of both sides of the inner side wall of the silo 1. The screen body 2 is movably connected in the two movable grooves 101. When the silo 1 is working, the screen body 2 is movably connected through the movable grooves 101 to provide support for the screen body 2 in the silo 1.

[0028] Furthermore, the end of the hopper 1 furthest from the sealing plate 106 is fixedly connected to two discharge hoppers 102. The two discharge hoppers 102 are vertically aligned and their output ends are staggered. The top of the screen body 2 is flush with the bottom of the upper discharge hopper 102, and the bottom of the lower discharge hopper 102 is flush with the bottom of the hopper 1. The top of the flexible sleeve 104 is fixedly connected to a receiving pipe 105. The hopper 1 discharges the screened material through the upper discharge hopper 102 and discharges the screened material through the lower discharge hopper 102. The top of the receiving pipe 105 is fixedly connected to the pipeline for conveying the material to be screened, so that during operation, the material to be screened is transferred to the hopper 1 for screening. The output end of the receiving pipe 105 is connected to the receiving equipment.

[0029] The operation process of this embodiment is as follows: During operation, the hopper 1 supports the screen body 2 through the movable groove 101 therein. When working, after the ultrasonic vibrator 304 generates excitation force, it drives the connecting block 303 to vibrate. Through the ultrasonic vibration of the connecting block 303, the hopper 1 and the screen body 2 therein vibrate. At the same time, the material is transferred and transported to the flexible sleeve 104 through the receiving pipe 105, and then transported to the feed pipe 103 through the flexible sleeve 104. The material is transported to the hopper 1 through the feed pipe 103 and falls onto the screen body 2 in the hopper 1. Through the ultrasonic vibration of the screen body 2, the qualified part of the material on the screen body 2 falls to the bottom of the hopper 1 and is transported to the discharge hopper 102 located at the lower end of the hopper 1. The material remaining on the screen body 2 after screening is transported to the discharge hopper 102 located at the upper end and output to the receiving equipment through the discharge hopper 102. Specific Implementation Example 2

[0030] Please see Figure 1-4 Based on the first specific embodiment, a handle 202 is fixed in the center of the side of the connecting plate 201 away from the sealing plate 106, and the end of the screen body 2 away from the connecting plate 201 abuts against the inner wall of the hopper 1. By pulling the handle 202 on the connecting plate 201, the screen body 2 is pulled out from the hopper 1.

[0031] Specifically, the top of the support base 3 is inclined and the four corners of the top of the support base 3 are all fixed with support legs 301. The top of each support leg 301 is fixed with a support spring 302. When the support base 3 is working, the hopper 1 is inclined and supported above the working plane by the inclined top setting. The support legs 301 fix the support spring 302 on it, and the support spring 302 supports the connecting block 303 on it.

[0032] Furthermore, each support spring 302 is fixed with a connecting block 303 at its top, and each connecting block 303 is fixed with an ultrasonic vibrator 304 at its top. Two connecting blocks 303 are fixed on each side of the hopper 1. When the support spring 302 is working, it is fixed to the hopper 1 through the connecting blocks 303, so that the ultrasonic vibration generated by the ultrasonic vibrator 304 drives the hopper 1 to vibrate.

[0033] The operation process of this embodiment is as follows: During operation, first, rotate the rotating plate 108 to a position away from the movable opening 109, then grasp the handle 202, support the screen body 2, align the screen body 2 with the movable opening 109 on the sealing plate 106, and then insert the screen body 2 into the movable opening 109 on the sealing plate 106, so that the screen body 2 is inserted into the movable groove 101 on the inner wall of the hopper 1, until the screen body 2 enters the hopper 1 and is in contact with the discharge hopper 102, and then rotates again. Rotate plate 108 so that it contacts connecting plate 201. After the position between connecting plate 201 and sealing plate 106 is determined, position screen body 2 in hopper 1. When it is necessary to adjust the screening accuracy, rotate rotating plate 108 away from connecting plate 201, pull handle 202, and pull connecting plate 201 and screen body 2 out of hopper 1. After reselecting screen body 2 with appropriate screening accuracy, repeat the above installation process to complete the adjustment of screening accuracy.
