[0044] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0045] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0046] See also Figure 1 , Figure 2 This embodiment provides a slurry filtering and equalizing device, which mainly includes: a distribution box 100, a filtering frame 200, a sealing frame 300 and an equalizing mechanism 600, etc.

[0047] like Figure 1 , Figure 2 As shown in the figure, the distribution box 100 is the main body for containing the ore pulp. A feed pipe 120 is inserted and fixedly connected in the middle of the upper box wall of the distribution box 100, which serves as the inlet of the ore pulp to be processed; two impurity outlets 135 are symmetrically opened on the upper part of the left box wall and the upper part of the right box wall of the distribution box 100, which serve as the outlet of impurities or large pieces of gangue; two equal distribution ports 155 are symmetrically opened on the lower part of the left box wall and the lower part of the right box wall of the distribution box 100, which serve as the outlet of the filtered ore pulp entering the equal distribution mechanism 600.

[0048] like Figure 1 , Figure 2As shown in , the filter frame 200 is an inverted V-shaped structure formed by splicing two filter plates, and the highest point of the center is opposite to the discharge end of the feed pipe 120. The filter frame 200 is embedded in the middle of the distribution box 100, and its left and right ends are located below the two impurity outlets 135, so as to facilitate the impurities or large pieces of gangue to be filtered out and discharged from the impurity outlets 135. In addition, the left end and the right end of the upper surface of the filter frame 200 are both provided with an upwardly protruding sealing strip 205 for fitting with the lower end of the sealing frame 300. At the same time, the setting of the filter frame 200 divides the internal space of the distribution box 100 into an upper first space 130 and a lower second space 150. The upper first space 130 is used to store the filtered impurities or large pieces of gangue, and is not easy to accumulate slurry, which is conducive to the separation of slurry and impurities.

[0049] like Figure 1 , Figure 2 As shown in , the sealing frame 300 is a frame body with an opening facing downwards embedded in the first space 130 inside the distribution box 100, and is used to slide up and down to control the opening and closing of the impurity outlet 135. Among them, the horizontal part 320 on the upper part of the sealing frame 300 is movably sleeved on the outer side of the discharge end of the feed pipe 120 to facilitate the inflow of slurry. The left and right end surfaces of the bottom of the sealing frame 300 are recessed inward to form two sealing grooves 305. The sealing grooves 305 correspond to the sealing strips 205 on the lower filter frame 200 in position and shape, and are used for embedded sealing to prevent the slurry from flowing out of the impurity outlet 135 when closed. At the same time, the horizontal part 320 on the upper part of the sealing frame 300 is also fixedly connected to the movable actuator composed of two electric push rods 400. The two electric push rods 400 are symmetrically arranged to pass through the upper box wall of the distribution box 100, and their output ends are fixedly connected to the horizontal part 320. Under the control of the two electric push rods 400 , the sealing frame 300 can slide up and down in the first space 130 , thereby realizing the opening and closing of the debris outlet 135 .

[0050] like Figure 1 , Figure 2 As shown in FIG. 1 , two equal distribution mechanisms 600 are arranged outside the distribution box 100 , facing the two equal distribution ports 155 , for further equal distribution and diversion of the filtered slurry.

[0051] The specific implementation of this embodiment is as follows: first, the slurry is injected into the distribution box 100 through the feed pipe 120. Then, the slurry is guided by the inverted V-shaped filter frame 200 to the filter screens in the two filter plates thereon, and the impurities in the slurry can be efficiently filtered out, and the filtered slurry flows downward to the second space 150 of the distribution box 100. Afterwards, the filtered slurry in the second space 150 flows into the equalization mechanism 600 through the equalization port 155 for equalization processing. When it is necessary to clean the impurities filtered out of the filter frame 200, the two electric push rods 400 are simultaneously contracted to drive the sealing frame 300 to move upward, so that the sealing groove 305 is separated from the sealing strip 205, and the two impurity outlets 135 are simultaneously opened, and the filtered impurities are conveniently and thoroughly cleaned out of the distribution box 100 through the opened two impurity outlets 135.

[0052] The slurry filtering and distributing device in this embodiment performs slurry filtering and impurity cleaning by setting a sealing frame 300 and a filtering frame 200. On the one hand, it avoids the occurrence of cleaning dead corners, making it easier to clean the filtered impurities in the device thoroughly, thereby improving the cleanliness of the device; on the other hand, it avoids the slurry being brought out when cleaning impurities, thereby reducing the waste of resources.

[0053] At the same time, in this embodiment, the filter frame 200 is set to an inverted V-shaped structure, which can guide the slurry entering the distribution box 100, and guide the slurry to the filter screens in the two filter plates thereon, which can effectively filter out impurities in the slurry, thereby improving the filtering efficiency of the device. In addition, the design of the inverted V-shaped structure also makes it easy for impurities to accumulate at the left and right ends of the filter frame 200 under the action of gravity, that is, the positions of the two impurity outlets 135, making it more convenient to clean the impurities.

[0054] Preferably, in this embodiment, two stopper plates 360 protruding laterally outward may be provided on the left and right sides of the sealing frame 300, facing the two outlets 135. The two stopper plates 360 are respectively accommodated in the two outlets 135. In the process of the sealing frame 300 moving up and down, when the stopper plates 360 contact the upper side of the outlet 135, the highest position of its movement is limited; when the stopper plates 360 contact the lower side of the outlet 135, the lowest position of its movement is limited. The limited moving position of the sealing frame 300 avoids it from hitting the upper box wall of the distribution box 100 or the filter frame 200, thereby improving the stability and safety of the device.

[0055] However, in the above embodiment, there are still problems of insufficient equal distribution and uneven distribution. In order to further solve this problem based on the first embodiment, the structure of the equal distribution mechanism 600 in the above embodiment is further improved.

[0056] See also Figure 3 , Figure 4, each equal distribution mechanism 600 provided in the second embodiment mainly includes: a shielding frame 620 and a plurality of diverters 660 and the like.

[0057] like Figure 3 As shown in , the shielding frame 620 is arranged outside the right box wall of the distribution box 100, and is located below the two equal distribution ports 155, and is arranged above the multiple diverters 660, mainly used to prevent the slurry flowing out of the equal distribution ports 155 from splashing. The left side of the top of the shielding frame 620 is fixedly connected to the right outer wall of the distribution box 100, and the right side is fixedly connected with a support frame 640, and the left end of the support frame 640 is fixedly connected to the right end of the distribution box 100. Among them, the support frame 640 is an L-shaped structure, including a horizontal plate part 644 and a vertical arm part 642, the upper horizontal plate part 644 is fixedly connected to the upper side of the equal distribution port 155 on the right outer wall of the distribution box 100, and the right vertical arm part 642 is fixedly connected to the top right side of the shielding frame 620.

[0058] like Figure 3 , Figure 4 As shown in , the multiple diverters 660 can be mainly divided into multiple diverter groups. Each diverter group is composed of a left diverter bucket 662, a middle diverter bucket 661 and a right diverter bucket 663 connected in sequence, and then multiple diverter groups are connected in parallel to form multiple diverters 660. The left end of each diverter bucket is fixedly connected to the right outer wall of the distribution box 100, and the right end of the right diverter bucket 663 is fixedly connected to the inner right frame wall of the shielding frame 620. Among them, the upper end inlets of the left diverter bucket 662, the middle diverter bucket 661 and the right diverter bucket 663 are the same size and connected side by side front and back, but the lower end outlets correspond to three different positions of left, middle and right, respectively, to divert the slurry into three parts.

[0059] When performing the equal distribution process, the slurry in the distribution box 100 flows out through the equal distribution port 155, so that the slurry flows into a plurality of left diversion buckets 662, middle diversion buckets 661 and right diversion buckets 663. The diversion mechanism on one side divides the slurry into three parts, namely, left, middle and right, and the two sides divide it into six parts, so that the slurry is adequately diverted. At the same time, since the upper end inlets of the left diversion bucket 662, middle diversion bucket 661 and right diversion bucket 663 are of the same size and connected in parallel in sequence, that is, the inlets of the three diversions on the left, middle and right are evenly distributed in the same plane, the slurry discharged from the diversion port 155 can be evenly distributed to the diversions in the three directions of left, middle and right, so that the diversions at each position can maintain uniform composition.

[0060] In this embodiment, the special diverter 660 structure composed of the left diverter 662, the middle diverter 661 and the right diverter 663 enables the diverting mechanism 600 to divert the slurry more fully and evenly, thereby improving the practicability of the device.

[0061] Furthermore, if Figure 3 , Figure 4 As shown in , an equalizing plate 684 can also be added to the equalizing mechanism 600 to control the flow of the equalizing port 155. At the same time, an adjustment plate 682 and an adjustment screw 680 are also provided in the equalizing mechanism 600. Among them, the adjustment screw 680 is threadedly connected to the center position of the cross plate part 644 of the support frame 640. The lower end of the adjustment screw 680 is connected to the adjustment plate 682 through a bearing for rotation. The adjustment plate 682 is arranged horizontally, and a limiting groove 683 is provided in the middle of its right end, and the limiting groove 683 is adapted to the shape of the vertical arm part 642 of the support frame 640, interlocked with each other, and can slide up and down. The left end of the adjustment plate 682 extends into the second space 150 through the equalizing port 155, and is fixedly connected to the equalizing plate 684. The averaging plate 684 is vertically arranged, and its side area is larger than the averaging port 155, so that it can be completely closed, and can be moved up and down to a suitable position under the control of the adjusting screw 680, so as to control the flow of the averaging port 155. By setting the averaging plate 684, the averaging port 155 can be adjusted according to the amount of slurry in the distribution box 100, and the appropriate flow rate is maintained to avoid the situation of excessive flow, which causes the slurry to splash or overflow in the diversion mechanism 600, thereby reducing the waste of resources.
