[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] like Figure 1 and Figure 2As shown, an ore dewatering screen includes a vibrating component 1, a filter component 2 fixedly connected to the upper part of the vibrating component 1, a feeding component 3 fixedly connected to the upper rear side of the filter component 2, a water outlet 5 opened on the lower left side of the filter component 2, and a motor 4 provided on the left side of the vibrating component 1.
[0027] Ore dewatering screens generally separate water-containing solid particles from water through vibration, achieving solid-liquid separation. Raw materials enter the screen surface of the dewatering screen through the feed hopper 302. Due to the continuous vibration of the dewatering screen, the particles diffuse on the screen surface. Smaller particles will flow through the screen holes to the bottom trough, while larger particles are blocked above the screen holes. Through continuous vibration and gravity, water molecules will be naturally discharged and flow out through the discharge port 204, thereby achieving dewatering.
[0028] The main function of an ore dewatering screen is not limited to dewatering. It can also separate and screen various materials. For example, it can effectively separate the muddy components from wet materials, remove the medium from materials, and classify the particle size of materials. It can achieve hydraulic classification, recover fine sand, thereby achieving a reasonable particle size distribution. At the same time, it can effectively recover the fine part of the material and improve the utilization rate of the material.
[0029] like Figure 3 , Figure 4 and Figure 7 As shown, the vibration assembly 1 includes a base 101. Springs 102 are fixedly connected to the four corners of the bottom wall of the base 101. Two rotating rods 103 are rotatably connected to the opposite surfaces of the two vertical parts of the base 101. Cams 104 are fixedly connected to the ends of the four rotating rods 103 near the middle of the base 101. Connecting rods 105 are fixedly connected to the protrusions of the two opposing cams 104 near each other. Rotating blocks 106 are rotatably connected to the outer surfaces of the two connecting rods 105. Rotating shafts 110 are rotatably connected to the upper sides of the two rotating blocks 106.
[0030] The filter assembly 2 has two slotted connecting blocks 109 fixedly connected to its lower end. Two rotating shafts 110 are rotatably connected to the middle of the lower end of the connecting blocks 109 on the same side. The ends of the four rotating rods 103 that are away from the middle of the base 101 all pass through the vertical part of the base 101 and are fixedly connected to pulleys 107. The outer surfaces of the two pulleys 107 located on the same vertical plane are connected to a belt 108. The end of one of the pulleys 107 that is away from the base 101 is fixedly connected to the output end of the motor 4 through a coupling. The motor 4 is fixedly installed on the side of the base 101. The two connecting blocks 109 are fixedly connected to two parallel connecting rods 111 at their opposite ends.
[0031] In actual use, after starting motor 4, motor 4 drives pulley 107 to rotate, and rotating rod 103 fixedly connected to pulley 107 also rotates. As a result, cam 104 fixedly connected to rotating rod 103 also rotates. Cam 104 drives connecting rod 105 and rotating block 106 to rotate, which in turn drives connecting block 109 and filter assembly 2 fixedly connected to it to move in the vertical direction. Because spring 102 is fixedly connected to the lower end of filter assembly 2, filter assembly 2 will start to vibrate.
[0032] like Figure 5 As shown, the filter assembly 2 includes a box 201 fixedly connected to the upper end of two connecting blocks 109. The box 201 is hollow inside and open at the top. The lower end of the box 201 is fixedly connected to the upper end of four springs 102. A sieve plate 1 202 is fixedly connected to the upper side of the inner wall of the box 201, and a sieve plate 203 is fixedly connected to the lower side of the inner wall of the box 201.
[0033] The first sieve plate 202 is set with the front lower than the back in the inner cavity of the box 201. The first sieve plate 202 leaves a gap on the front side of the inner cavity of the box 201. The second sieve plate 203 is set with the front higher than the back in the inner cavity of the box 201. The front end and the rear end of the second sieve plate 203 are fixedly connected to the inner wall of the box 201.
[0034] The rear side of the housing 201 is provided with a discharge port 204. The bottom wall of the inner cavity of the discharge port 204 is at the same level as the lowest point of the upper end of the second screen plate 203. In actual use, the ore slides down on the inclined screen plate 202 after being vibrated by the vibration component 1. It falls onto the second screen plate 203 through the gap between the first screen plate 202 and the front side of the inner cavity of the housing 201, and then slides towards the discharge port 204 through the inclined screen plate 203.
[0035] like Figure 6 As shown, the feeding assembly 3 includes a frame 301 fixedly connected to the rear side of the upper end of the box 201. The frame 301 is hollow inside and open at both the upper and lower ends. A feeding hopper 302 is fixedly connected to the upper end of the frame 301. The feeding hopper 302 is a truncated pyramid with a larger upper end and a smaller lower end. It is hollow inside and open at both the upper and lower ends. The larger upper end and smaller lower end of the feeding hopper 302 facilitates the pouring of ore into it.
[0036] Two parallel rolling rollers 303 are rotatably connected to the inner wall of the frame 301. The left and right ends of the two rolling rollers 303 extend through the inner surface of the frame 301 to the outside and are fixedly connected to gears 304. The two gears 304 on the same side mesh with each other. A support 305 is fixedly connected to the lower right side of the frame 301. A motor 306 is fixedly connected to the upper end of the support 305. The output end of the motor 306 is fixedly connected to the gear 304 opposite to it through a coupling.
[0037] The main function of the crushing roller 303 is to crush and disperse the ore, making it enter the filter assembly 2 more evenly. This can reduce the possibility of clogging and agglomeration, thereby improving the dewatering efficiency. On the one hand, adding the crushing roller 303 may slow down the feeding speed to some extent, because the ore will be subjected to additional resistance and agitation during the crushing process, which may reduce the speed at which the ore passes through the feed hopper 302. On the other hand, the crushing roller 303 effectively crushes the ore and avoids clogging, so it may actually maintain or even improve the overall feeding efficiency, because the dewatering screen can process the ore more continuously and stably.
[0038] It should be noted that the specific installation method, circuit connection method and control method of motor 306 and motor 4 used in this utility model are all conventional designs, and will not be described in detail in this utility model.
[0039] The working principle of this utility model is as follows: First, motor 4 is started, which drives pulley 107 to rotate. Rotating rod 103, fixedly connected to pulley 107, also rotates, causing cam 104, fixedly connected to rotating rod 103, to rotate as well. Cam 104 drives connecting rod 105 and rotating block 106 to rotate, which in turn drives connecting block 109 and filter assembly 2, fixedly connected to it, to move vertically. Because spring 102 is fixedly connected to the lower end of filter assembly 2, filter assembly 2 will begin to vibrate. Then, motor 306 is started, which drives gear 304 to rotate. Gear 304 drives crushing roller 303, fixedly connected to it, to rotate. Then, the ore to be dewatered is poured into feed hopper 302. After being crushed by crushing roller 303, the ore falls at a uniform speed into screen plate 20. 2. Under the vibration of the vibrating component 1, liquid and small-diameter mud and sand will fall from the filter holes onto the lower screen plate 203, and then fall through the filter holes on the screen plate 203 into the bottom wall of the box 201. The ore remaining on the screen plate 202 will slide onto the screen plate 203 under the action of the vibrating component 1 and the inclined screen plate 202. Then the screen plate 203 can perform secondary dewatering and filtration on the ore. The liquid part directly passes through the filter holes on the screen plate 203 and falls into the bottom wall of the box 201. The ore after two dewatering and filtration will slide along the inclined screen plate 203 to the discharge port 204 under the action of the vibrating component 1. The operator can collect the dewatered ore. After dewatering, the operator can open the water outlet 5 to discharge the water and small-diameter mud and sand in the box 201.
