Description

Technical Field

[0001] This utility model relates to the technical field of screening machinery, specifically to an electromagnetic vibrating dewatering screen. Background Technology

[0002] The main function of a dewatering screen is dewatering, desliming, and demediuming. It can be used in sand and gravel plants for washing sand, coal preparation plants for coal slime recovery, and tailings dry discharge in mineral processing plants. Therefore, it is also called a sand and gravel dewatering screen, a mining dewatering screen, a coal slime dewatering screen, and a tailings dewatering screen. Dewatering screens typically use a vibrating motor to make the screen box reciprocate periodically in a straight line to achieve the purpose of grading and dewatering.

[0003] In existing technology, patent CN208809585U discloses a novel dewatering screen, including support legs and a base above the support legs. A screen box inclined at a certain angle is disposed above the base. Support seats are provided at both ends of the bottom plate of the screen box, and a screen mesh is fixed above the support seats. A vibrating motor is disposed on the cover of the screen box, and the vibrating motor includes two sets of eccentric blocks. A discharge port is provided at the higher end of the screen box, and a hole is opened on the bottom plate of the lower end of the screen box, which is connected to a water storage tank located below the bottom plate via a pipe. A drain outlet is provided at the bottom of the water storage tank. By tilting the screen box and using the vibrating motor with eccentric blocks, the screen mesh can move linearly back and forth in the inclined direction.

[0004] The existing technical solutions mentioned above have the following drawbacks: the material is continuously transported horizontally by vibration alone, resulting in a slow material transport rate. When a large amount of material enters the screen box from the feed inlet of the dewatering screen, the material is transported slowly because the vibration of the vibrating motor alone causes the material to vibrate within the screen box. This may lead to material accumulation at the feed inlet, resulting in a larger material thickness during transport and affecting the dewatering effect and rate.

[0005] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

[0006] This invention proposes an electromagnetic vibrating dewatering screen, which solves the problem in related technologies that the material is vibrated in the screen box by the vibration of a vibrating motor alone, resulting in a slow material transmission rate, which may cause material to accumulate at the feed inlet and make the material thickness during transmission large, thus affecting the dewatering effect and rate.

[0007] The technical solution of this utility model is as follows: including...

[0008] A pair of base frames and a housing, the housing being mounted on the base frames;

[0009] A spray assembly, wherein the spray assembly is disposed on the top of the housing;

[0010] A vibration dehydration assembly is disposed on the top of the housing;

[0011] Feeding components are disposed at both ends of the housing;

[0012] The vibration dehydration assembly includes a pair of top frames, each fixed to the top of the outer shell. Each top frame is equipped with a pair of vibration motors. Dehydration mesh holes are provided on both inner surfaces of the outer shell, and a pair of drainage covers are provided at the bottom of the outer shell.

[0013] As a further technical solution, a circular pipe is connected to the bottom of the outer shell, the top of the circular pipe is connected to the inside of the outer shell, a conveying auger is installed inside the circular pipe, and one end of the circular pipe is an open structure.

[0014] As a further technical solution, the top of the base frame is provided with several shock-absorbing bases, which are connected to the bottom surface of the drainage cover. The inner bottom surface of the outer shell and the bottom surface of the drainage cover are both inclined structural surfaces.

[0015] As a further technical solution, the feeding assembly includes a pair of hydraulic cylinders, which are respectively fixed on the outer surfaces of the housing. The output end of the hydraulic cylinder is connected to a feeding box, and a pair of connecting blocks are provided on both sides of the housing.

[0016] As a further technical solution, external fixing ears are provided on both sides of the feeding box, and a movable column is provided at the bottom of the external fixing ears. The movable column is slidably connected to the connecting block, and the bottom of the feeding box is located at the upper end of the inner bottom surface of the outer shell.

[0017] As a further technical solution, the spray assembly includes a support frame, which is disposed on the side surface of the housing. A water inlet pipe is fixedly connected to the side surface of the support frame, and a plurality of spray nozzles are disposed on the water inlet pipe.

[0018] As a further technical solution, both inner surfaces of the outer shell are inclined towards the circular pipe.

[0019] As a further technical solution, the top cross-section of the feed box has a funnel-shaped opening structure.

[0020] As a further technical solution, the spray nozzles all have a certain tilt angle, and the spray nozzles adopt a mist spraying structure.

[0021] The working principle and beneficial effects of this utility model are as follows:

[0022] 1. This utility model is equipped with a vibration dewatering component. Through the interaction of structures such as the vibration motor, dewatering mesh, circular pipe, conveying auger and shock-absorbing base, dewatering starts synchronously through the dewatering mesh on both sides. With the vibration, the material can move downward evenly and be discharged in a concentrated manner, which has a very good dewatering effect.

[0023] 2. This utility model is equipped with a feeding component. Through the interaction of the hydraulic cylinder, the feeding box and the movable column, the feeding speed can be adjusted by controlling the height of the feeding box, so that the material moves downward more evenly and will not accumulate, thus affecting the dewatering efficiency.

[0035] Feeding assembly 4 is disposed at both ends of the outer casing 2;

[0036] The vibrating dehydration assembly 3 includes a pair of top frames 3-1, both of which are fixed to the top of the outer shell 2. A pair of vibrating motors 3-2 are installed on the top of each top frame 3-1. Dehydration mesh holes 3-3 are opened on both inner surfaces of the outer shell 2.

[0037] In this embodiment, in order to achieve uniform vibration dehydration, a vibration dehydration component 3 is designed. Two top frames 3-1 are set on the top of the outer shell 2, and vibration motors 3-2 are installed on the surface of each frame, which can make the outer shell 2 vibrate. A dehydration mesh 3-3 is opened on the bottom surface of the inner shell 2, and a drain gate is installed at the bottom.

[0044] Furthermore, the top cross-section of the feed box 4-2 has a funnel-shaped opening structure.

[0046] Furthermore, the spray nozzles 5-3 all have a certain tilt angle, and the spray nozzles 5-3 adopt a mist spraying structure.

[0047] In this embodiment, by tilting the nozzle at an angle and using a mist spraying structure, the spray nozzle 5-3 can better cover all positions of the dewatering mesh 3-3.

Start the conveying auger 3-6 to push the material outward. When cleaning is required, connect the water inlet pipe 5-2 to the water supply equipment and turn on the spray nozzle 5-3 to spray and rinse the dehydration mesh 3-3.
