Description

Technical Field

[0001] This utility model relates to the field of dewatering screen technology, and in particular to a pedestal dewatering screen that can improve dewatering efficiency. Background Technology

[0002] Dewatering screens are mainly used for dewatering, desliming, and demediuming. They can be used for washing sand in sand and gravel plants, recovering coal slime in coal preparation plants, and dry discharge of tailings in mineral processing plants. Therefore, they are also called sand and gravel dewatering screens, mining dewatering screens, coal slime dewatering screens, and tailings dewatering screens.

[0003] Existing mining dewatering screens rely mainly on the excitation force generated by a vibrating motor to move the material on the screen, thereby achieving solid-liquid separation. However, because the material moves along a single trajectory on the screen, it tends to accumulate, resulting in low dewatering efficiency. Utility Model Content

[0004] In view of this, the present invention provides a seat-type dewatering screen that can improve dewatering efficiency. The main technical problem to be solved is that the material is prone to accumulation due to the single material movement trajectory, which leads to low material dewatering efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a seated dewatering screen that can improve dewatering efficiency, comprising a shell, wherein a dewatering screen and a guide plate are fixedly connected from top to bottom on the inner side of the shell, a buffer device is fixedly connected to the lower part of the shell, and a base is fixedly connected to the lower part of the buffer device, the dewatering screen includes a screen plate fixedly connected to the inner side of the shell, the screen plate has screen holes inside, and a discharge plate is fixedly connected to the lower end of the screen plate.

[0006] By adopting the above technical solution, the vibration motor is started during use to generate an oscillating force, causing the fixed column to move up and down continuously inside the fixed cylinder. This, in turn, drives the outer shell to move the dewatering screen up and down continuously. The material is then poured into the outer shell through the feed inlet. Under the action of gravity, the material falls onto the screen plate and moves downward along the screen plate under the action of gravity and oscillation force. Under the action of gravity and oscillation force, the water on the material can flow out through the screen holes, thus separating the material from the water. The screen plate has a spiral structure, which prevents the material from moving in a single direction when it moves downward, thus preventing the material from accumulating in one place and ensuring higher dewatering efficiency. Furthermore, the spiral screen plate allows the material to stay on the screen plate for a longer time, further improving the dewatering efficiency.

[0007] As a further description of the above technical solution: the outer shell includes a base plate, an outer cylinder is fixedly connected to the top of the base plate, a vibration motor is fixedly connected to the lower outer side of the outer cylinder, an inner cylinder is fixedly connected to the middle of the top of the base plate, a top plate is fixedly connected to the top of the outer cylinder and the inner cylinder, a feed port is provided inside the top plate, and a baffle is fixedly connected to the upper part between the outer cylinder and the inner cylinder.

[0008] By adopting the above technical solution, the feed inlet is used to allow materials to enter the outer shell, and the baffle is used to block the materials from the dewatering screen and the water separated on the guide plate.

[0009] As a further description of the above technical solution: the guide plate includes a plate body fixedly connected to the inside of the outer shell, and a water outlet plate is fixedly connected to the lower end of the plate body.

[0010] By adopting the above technical solution, the plate is used to guide the separated water, the water outlet plate is used to discharge the separated water, and the length of the water outlet plate is shorter than the length of the material outlet plate, which facilitates the collection of the material discharged from the material outlet plate.

[0011] As a further description of the above technical solution: the buffer device includes a fixed cylinder fixedly connected to the top of the base, a fixed column movably connected inside the fixed cylinder, a fixed block fixedly connected to the lower end of the fixed column, a rubber sleeve fixedly connected to the outer side of the fixed block, a spring fixedly connected between the fixed cylinder and the fixed column, and the fixed column fixedly connected to the base plate.

[0012] By adopting the above technical solution, starting the vibration motor enables the fixed column to drive the fixed block to rise and fall inside the fixed cylinder, and the rubber sleeve ensures that the movement of the fixed block and the fixed column is not too large, thus guaranteeing the stability of the equipment operation.

[0013] As a further description of the above technical solution: the base includes a seat body fixedly connected to the lower part of the fixed cylinder, and a buffer pad is fixedly connected to the lower part of the seat body. The seat body and the buffer pad are provided with a fixing groove inside.

[0014] By adopting the above technical solution, the buffer pad is used to buffer the vibration generated during equipment operation, and the fixing groove is used to fix the equipment.

[0015] As a further description of the above technical solution: both the sieve plate and the plate body are spiral structures arranged between the outer cylinder and the inner cylinder.

[0016] By adopting the above technical solution, the spiral structure of the screen plate allows the material to stay on the screen plate for a longer time, and it will not easily cause material accumulation due to a single direction of movement, thus improving the dewatering efficiency.

[0017] As a further description of the above technical solution: the length of the discharge plate is greater than the length of the water discharge plate.

[0018] By adopting the above technical solution, it is convenient to collect the materials discharged from the discharge plate.

[0019] As a further description of the above technical solution: the cushioning pad is made of rubber.

[0020] By adopting the above technical solution, the buffer pad is used to buffer the vibration generated during equipment operation, ensuring that the vibration generated by the equipment will not be transmitted to other equipment through the ground.

[0021] By employing the above technical solution, the pedestal dewatering screen of this utility model, which can improve dewatering efficiency, has at least the following beneficial effects:

[0022] Compared with existing technologies, this type of seated dewatering screen, which improves dewatering efficiency, enhances the dewatering efficiency of materials. During operation, a vibrating motor generates an oscillating force, causing the fixed column to move up and down continuously inside the fixed cylinder. This, in turn, drives the outer shell, causing the dewatering screen to move up and down continuously. Material is then poured into the outer shell through the feed inlet. Under gravity, the material falls onto the screen plate and moves downwards along the screen plate under the combined effects of gravity and oscillation. The water on the material flows out through the screen holes, separating the material from the water. The spiral structure of the screen plate prevents the material from moving in a single direction, thus preventing material accumulation and ensuring higher dewatering efficiency. Furthermore, the spiral shape of the screen plate allows the material to remain on the screen for a longer period, further improving dewatering efficiency. Attached Figure Description

[0029] Reference Figure 1-4 This utility model provides a seated dewatering screen that can improve dewatering efficiency. It includes a housing 1, with a dewatering screen 2 and a guide plate 3 fixedly connected sequentially from top to bottom on the inner side of the housing 1. A buffer device 4 is fixedly connected to the lower part of the housing 1, and a base 5 is fixedly connected to the lower part of the buffer device 4. The dewatering screen 2 includes a screen plate 201 fixedly connected to the inner side of the housing 1. The screen plate 201 has screen holes 202 inside, and a discharge plate 203 is fixedly connected to the lower end of the screen plate 201. During use, the vibration motor 102 is activated to generate an oscillating force, causing the fixed column 405 to move continuously up and down inside the fixed cylinder 401, thereby driving the housing 1 and causing the dewatering screen 2 to move continuously up and down. Then, the material is poured into the outer shell 1 through the feed inlet 105. Under the action of gravity, the material falls onto the screen plate 201 and moves downward along the screen plate 201 under the action of gravity and turbulence. Under the action of gravity and turbulence, the water on the material can flow out through the screen holes 202, thereby separating the material from the water on the material. The screen plate 201 has a spiral structure, which prevents the material from moving downward in a single direction, thus preventing the material from accumulating in one place and ensuring higher dewatering efficiency. Furthermore, the spiral shape of the screen plate 201 allows the material to stay on the screen plate 201 for a longer time, further improving the dewatering efficiency.

[0030] Furthermore, the outer shell 1 includes a base plate 101, an outer cylinder 103 is fixedly connected to the top of the base plate 101, a vibration motor 102 is fixedly connected to the lower outer side of the outer cylinder 103, and the vibration motor 102 is activated to generate an agitation force. An inner cylinder 107 is fixedly connected to the middle of the top of the base plate 101, and a top plate 106 is fixedly connected to the top of the outer cylinder 103 and the inner cylinder 107. The top plate 106 has a feed inlet 105 inside, which allows materials to enter the outer shell 1. A baffle 104 is fixedly connected to the upper part between the outer cylinder 103 and the inner cylinder 107, which is used to block the material of the dewatering screen 2 and the water separated on the guide plate 3.

[0031] Furthermore, the guide plate 3 includes a plate 301 fixedly connected to the inside of the housing 1. The plate 301 is used to guide the separated water. A water outlet plate 302 is fixedly connected to the lower end of the plate 301. The water outlet plate 302 is used to discharge the separated water.

[0032] Furthermore, the buffer device 4 includes a fixed cylinder 401 fixedly connected to the top of the base 5. A fixed column 405 is movably connected inside the fixed cylinder 401. The fixed column 405 can move up and down inside the fixed cylinder 401. A fixed block 404 is fixedly connected to the lower end of the fixed column 405. A rubber sleeve 403 is fixedly connected to the outside of the fixed block 404. The rubber sleeve 403 fits against the inner wall of the fixed cylinder 401. A spring 402 is fixedly connected between the fixed cylinder 401 and the fixed column 405. The fixed column 405 is fixedly connected to the base plate 101. When the vibration motor 102 is started, the fixed column 405 can drive the fixed block 404 to move up and down inside the fixed cylinder 401. Under the action of the rubber sleeve 403, the movement range of the fixed block 404 and the fixed column 405 will not be too large, ensuring the stability of the equipment operation.

[0033] Furthermore, the base 5 includes a seat body 501 fixedly connected to the lower part of the fixed cylinder 401. A buffer pad 502 is fixedly connected to the lower part of the seat body 501. The seat body 501 and the buffer pad 502 are provided with a fixing groove 503 inside, which is used to fix the equipment.

[0034] Furthermore, both the sieve plate 201 and the plate body 301 are spirally arranged between the outer cylinder 103 and the inner cylinder 107. The spiral structure of the sieve plate 201 allows the material to stay on the sieve plate 201 for a longer time, and it will not easily cause material accumulation due to a single direction of movement, thus improving the dewatering efficiency.

[0035] Furthermore, the length of the discharge plate 203 is greater than the length of the water discharge plate 302, which facilitates the collection of the material discharged from the discharge plate 203.

[0036] Furthermore, the buffer pad 502 is made of rubber and is used to buffer the vibrations generated during equipment operation, ensuring that the vibrations generated by the equipment are not transmitted to other equipment through the ground.

[0037] Working principle: During use, the vibration motor 102 is started to generate an oscillating force, which causes the fixed column 405 to move up and down continuously inside the fixed cylinder 401. This, in turn, drives the outer shell 1 to move the dewatering screen 2 up and down continuously. Then, the material is poured into the outer shell 1 through the feed port 105. Under the action of gravity, the material falls onto the screen plate 201 and moves downward along the screen plate 201 under the action of gravity and oscillation force. Under the action of gravity and oscillation force, the water on the material can flow out through the screen holes 202 and be discharged from the outer shell 1 by the guide plate 3. This separates the material from the water on the material. The screen plate 201 has a spiral structure, which prevents the material from moving in a single direction when it moves downward, thus preventing the material from accumulating in one place and ensuring higher dewatering efficiency. Furthermore, the spiral shape of the screen plate 201 allows the material to stay on the screen plate 201 for a longer time, further improving the dewatering efficiency.
