Description

Technical Field

[0001] The invention relates to the field of sludge treatment, and more particularly to a sludge distributor for a mine filter press. Background Art

[0002] During mining and related processing, a large amount of mud waste is generated. These muds need to be processed by filter pressing to achieve solid-liquid separation and subsequent resource recovery or environmental protection disposal. However, there are many problems in the traditional way of conveying mud to the filter press, which seriously affects the working efficiency and effect of the filter press.

[0003] Normally, it is difficult to achieve uniform distribution of mud when it enters the filter press. This is because the source of mining mud is complex, its composition and physical properties are different, and it is easy to sediment and segregate during transportation. Therefore, a mud distributor is needed to evenly distribute the mud.

[0004] For example, a Chinese patent with authorization announcement number CN109336355B discloses a mud distributor for a filter press, in which the mud and water can automatically flow downward along the homogenizing plate after being sprayed onto the homogenizing plate through the discharge port, and the mud is evenly distributed in a fan shape, so that the mud is more evenly distributed when entering the filter press, thereby improving the extrusion efficiency of the filter press.

[0005] However, with the development of the mining industry, the efficiency and quality requirements for mud treatment are getting higher and higher. The traditional mud distribution method can no longer meet the needs of modern mining production. Therefore, the development of a mud distributor for mine filter press that can effectively solve the problem of uneven mud distribution and improve the extrusion efficiency of the filter press has important practical significance in the field of sludge treatment.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0032] Example: See Figure 1-11 A mud distributor for a mine filter press comprises an intermittent feeding mechanism 2, a mud uniform distribution mechanism 3 is fixedly connected to the lower side of the intermittent feeding mechanism 2, the mud uniform distribution mechanism 3 comprises a mud distribution chamber 14, a rectangular mud uniform space is provided inside the mud distribution chamber 14, a second feed port connected to the upper side of the rectangular mud uniform space is provided in the middle position of the upper side of the mud distribution chamber 14, the rectangular mud uniform space is connected to the second feed port, and is used for intermittently feeding mud into the rectangular mud uniform space through the second feed port.

[0033] The lower side of the mud distribution chamber 14 is open to form a discharge port. A discharge valve plate 4 is installed on the lower side of the mud distribution chamber 14. The discharge valve plate 4 is used to block and seal the discharge port of the discharge valve plate 4. When the discharge valve plate 4 is opened, the mud in the rectangular mud equalization space is discharged through the discharge port.

[0034] A mud distribution detector may be fixedly connected to the outside of the mud distribution chamber 14 for monitoring the mud distribution inside the rectangular mud distribution space. The mud distribution detector may include a plurality of ultrasonic sensors fixedly connected to the outside of the mud distribution chamber 14 for detecting the mud distribution using ultrasonic waves.

[0035] like Figure 4-5 and Figure 8As shown, in order to make the mud inside the rectangular mud equalizing space more evenly distributed, the front and rear sides of the mud distribution chamber 14 are fixedly connected with the second electric push rod 15, and the piston rod of the second electric push rod 15 extends to the inside of the rectangular mud equalizing space and is fixedly connected with a mud pushing plate 16. There are two mud pushing plates 16 in total. The mud entering through the second feed port will fall between the two mud pushing plates 16. The sides of the two mud pushing plates 16 close to each other are a zigzag contact surface in contact with the mud, and the horizontal section of the zigzag contact surface is a zigzag shape. The bending part of the mud pushing plate 16 is a corner portion, and the mud pushing plate 16 between two adjacent corner portions is an extrusion portion. The horizontal position of the corner portion can be along the center line between the two mud pushing plates 16 Direction adjustment, the center line direction between the two mud pushing plates 16 and the width direction of the mud distribution chamber 14 are arranged in parallel, and the spacing between the angle part and the second electric push rod 15 is adjustable, so that the inclination of the extrusion part is adjustable. At this time, the horizontal position of the angle part can be adjusted according to the mud distribution inside the rectangular mud distribution space, so that the inclination of the extrusion part can be adjusted, so that the shape of the broken line contact surface is adapted to the mud distribution, and a greater thrust is applied to the area where the mud is more concentrated, so as to drive the mud in this area to move quickly along the width direction of the mud distribution chamber 14, and push the mud to the area with less mud distribution, so as to quickly push the mud to be evenly distributed along the center line direction between the two mud pushing plates 16.

[0036] Here, the second electric push rod 15 can be replaced by other devices that can drive the mud pusher 16 to move.

[0037] Specifically, Figure 7-10 As shown, the mud pushing plate 16 includes a main board body 26 fixedly connected to the piston rod of the second electric push rod 15, and a mud pushing piece 27 is assembled on the side of the main board body 26 away from the second electric push rod 15, and both ends of the main board body 26 are connected to the mud pushing piece 27 for positioning the mud pushing piece 27, and the side surface of the mud pushing piece 27 away from the main board body 26 is a folded line contact surface, and the upper end and the lower end of the mud pushing piece 27 close to the main board body 26 are fixedly connected with a connecting strip 39, and a plurality of adjustment groups 28 located between the main board body 26 and the mud pushing piece 27 are fixedly connected to the main board body 26, and a connecting round rod 38 is fixedly connected to the end of the adjustment group 28 away from the main board body 26, and the connecting round rod 38 and the connecting strip 39 are slidably connected. At this time, the shape of the folded line contact surface can be adjusted by adjusting the position of the connecting round rod 38 by the adjustment group 28, so that the shape of the folded line contact surface can be freely set according to the needs of the user.

[0038] The function of the adjustment group 28 is to drive the connecting rod 38 to move horizontally. It can be a manipulator fixedly connected to the main body 26, which drives the connecting rod 38 to move horizontally through the manipulator, or it can be an adjustment arm that can move on the main body 26. In the present technical solution, it is preferably an adjustment arm that can move on the main body 26. Figure 9-11As shown, a horizontally arranged guide slide bar 29 and a first gear rack 34 are fixedly connected to one side of the main body 26 away from the second electric push rod 15, and the adjustment group 28 includes a slider 30 slidably connected to the guide slide bar 29, and a motor mounting plate 31 is fixedly connected to the slider 30, and a second transmission motor 32 is fixedly connected to the motor mounting plate 31, and a second gear 33 meshing with the first gear rack 34 is fixedly connected to the output end of the second transmission motor 32. At this time, the second gear 33 can be driven to rotate by starting the second transmission motor 32. When the second gear 33 rotates, it will drive the slider 30 to move under the pushing action of the meshing between it and the first gear rack 34, and the second transmission motor 32 needs to have self-locking property, and locks the position of the slider 30 after the movement is completed. An electric telescopic structure fixedly connected to the slider 30 and a connecting rod 38 is fixedly connected. The connecting rod 38 is driven to move by the electric telescopic structure, so that the distance between the connecting rod 38 and the mud push plate 16 can be adjusted, and the distance between the connecting rod 38 and the second electric push rod 15 can also be adjusted.

[0039] Moreover, in order to enhance the locking stability of the slider 30, at least the area on the main board 26 opposite to the slider 30 is made of iron, and an electromagnet 35 is fixedly connected to the slider 30. When the electromagnet 35 is energized, it can use magnetic force to adsorb and lock the slider 30 on the main board 26, thereby enhancing its locking stability.

[0040] like Figure 9-11 As shown, the electric telescopic structure can be an electric push rod. In order to reduce the volume of the electric telescopic structure in this technical solution, a motor transmission structure is selected, which is specifically, the electric telescopic structure includes an outer sleeve 36 fixedly connected to the slider 30, and the inner sleeve 36 is slidably connected to the inner support plate 37. The end of the inner support plate 37 away from the slider 30 extends to the outside of the outer sleeve 36 and is fixedly connected to the connecting rod 38. When the inner support plate 37 moves, it can drive the connecting rod 38 to move. The second gear rack 40 is fixedly connected to the inner support plate 37, and the outer sleeve 36 is rotatably connected to the position away from the slider 30. A rotating rod 41 is provided, and a worm gear 42 and a third gear 43 are fixedly connected to the outer side of the rotating rod 41. The third gear 43 is meshingly connected to the second rack bar 40. A third transmission motor 44 is fixedly connected to the outer side of the outer sleeve 36. A worm 45 is fixedly connected to the output end of the third transmission motor 44. The worm 45 is meshingly connected to the worm wheel 42. At this time, the worm 45 can be driven to rotate by starting the third transmission motor 44. When the worm 45 rotates, it will drive the third gear 43 to rotate through the rotating rod 41. When the third gear 43 rotates, it will push the second rack bar 40 to drive the inner support plate 37 to move.

[0041] At the same time, if Figure 7-8As shown, both ends of the mud pushing piece 27 can be fixedly connected to the two ends of the main board body 26. In order to better adjust the mud pushing piece 27, the technical solution chooses to improve the installation method of the mud pushing piece 27. Specifically, the two ends of the mud pushing piece 27 are respectively a fixed end and a movable end. The fixed end of the mud pushing piece 27 is fixedly connected to one end of the main board body 26, and the side where the main board body 26 and the piston rod of the second electric push rod 15 are connected is the rear side. The rear side of the main board body 26 is fixedly connected with the third electric push rod 46, and the movable end of the mud pushing piece 27 bypasses the other end of the main board body 26 and extends to the rear side of the main board body 26 and is fixedly connected to the piston rod of the third electric push rod 46. At this time, the movable end of the mud pushing piece 27 can be driven to move by starting the connecting round rod 38. After the position adjustment of the connecting round rod 38 is completed, the third electric push rod 46 is started to tighten the mud pushing piece 27, thereby reducing the restriction of the fixed-length mud pushing piece 27 on the position of the connecting round rod 38.

[0042] Among them, Figure 2-5 As shown, the discharge valve plate 4 includes four guide rail bodies 17 fixedly connected to the lower side of the mud distributing chamber 14. Among the four guide rail bodies 17, two guide rail bodies 17 opposite to each other along the width direction of the mud distributing chamber 14 form a group. A second gate plate 18 located at the lower side of the mud distributing chamber 14 is slidably connected between the guide rail bodies 17 in the same group. When the two second gate plates 18 slide to abut each other, the discharge port of the mud distributing chamber 14 can be blocked and sealed. When the two second gate plates 18 slide apart, the mud inside the mud distributing chamber 14 can be discharged through the area between the two second gate plates 18.

[0043] like Figure 4-6 As shown, a first transmission motor 19 is fixedly connected to the guide rail body 17, and an output end of the first transmission motor 19 is fixedly connected to a first meshing gear 21 located at the lower side of the second gate plate 18. A meshing groove 20 is provided on the lower side of the second gate plate 18, and the meshing groove 20 and the first meshing gear 21 are meshed and connected. At this time, by starting the first transmission motor 19, the meshing groove 20 can be pushed by the rotating first meshing gear 21, so that the first meshing gear 21 drives the second gate plate 18 to move horizontally.

[0044] like Figure 2 and Figure 4-5As shown, the intermittent feeding mechanism 2 includes a rectangular feeding shell 8 fixedly connected to the upper side of the mud distribution chamber 14, the lower end of the rectangular feeding shell 8 is connected to the second feeding port, and the inner walls on the front and rear sides of the rectangular feeding shell 8 are fixedly connected with material guide partitions 11, and a material discharge channel is formed between the two material guide partitions 11. The rectangular feeding shell 8 is equipped with a gate group that can close the material discharge channel. When the mud enters the rectangular feeding shell 8, the gate group is intermittently opened. When the gate group is in an open state, the material can be fed into the rectangular mud distribution space through the material discharge channel. When the gate group is in a closed state, the feeding is stopped. At this time, the mud entering the rectangular mud distribution space can be squeezed by two mud pushing plates 16, so that the mud is evenly distributed along the width direction of the mud distribution chamber 14.

[0045] Specifically, the material guide baffle 11 includes a material guide inclined plate 22, a material guide vertical plate 23, and a material guide bottom plate 24 fixedly connected to the inside of the rectangular feed shell 8. Both sides of the material guide inclined plate 22, the material guide vertical plate 23, and the material guide bottom plate 24 are fixedly connected to the inner walls of the two sides of the rectangular feed shell 8. The two material guide vertical plates 23 are vertically arranged, and the material discharge channel is the space between the two material guide vertical plates 23. The material guide inclined plate 22 is fixedly connected to the upper end of the material guide vertical plate 23. The upper ends of the two material guide inclined plates 22 are inclined in a direction away from each other, and the upper ends of the two material guide inclined plates 22 are respectively fixedly connected to the inner walls of the front and rear sides of the rectangular feed shell 8 to form an inclined surface. When the mud falls into the inside of the rectangular feed shell 8, it will fall into the material discharge channel under the guidance of the material guide inclined plate 22. Inside the channel, the two material guide bottom plates 24 are horizontally arranged, and the ends of the two material guide bottom plates 24 that are close to each other are fixedly connected to the lower ends of the two material guide vertical plates 23, and the ends of the two material guide bottom plates 24 that are away from each other are fixedly connected to the inner walls of the front and rear sides of the rectangular feed shell 8, respectively. The gate group includes a first electric push rod 12 fixedly connected to the rectangular feed shell 8, the piston rod of the first electric push rod 12 extends to the space between the rectangular feed shell 8 and the material guide vertical plates 23, and the first gate 13 is fixedly connected to the inside, one of the material guide vertical plates 23 is provided with a transverse groove 25 near the material guide bottom plate 24, the first gate 13 passes through the transverse groove 25, and the first gate 13 can be moved to the inside of the material discharge channel to block the material discharge channel.

[0046] At this time, the first gate plate 13, the mud distribution chamber 14, the second gate plate 18 and the material guiding bottom plate 24 form a relatively regular rectangular mud uniform space.

[0047] At the same time, a sewage overflow groove 9 is opened on the side wall of the rectangular feed shell 8 at the upper side of the guide partition 11, and a water guide plate 10 is fixedly connected to the outer side of the side wall of the rectangular feed shell 8 where the sewage overflow groove 9 is opened. The water guide plate 10 is located at the lower side of the sewage overflow groove 9, and the end of the water guide plate 10 away from the sewage overflow groove 9 is inclined downward. At this time, when the gate group is in a closed state, excess sewage can be discharged outward through the sewage overflow groove 9 and directly fall into the filter press below the mud distributor.

[0048] like Figure 1-3 As shown, the upper end of the intermittent feeding mechanism 2 can also be fixedly connected to a mud feeding pre-uniform distribution mechanism 1, and the mud feeding pre-uniform distribution mechanism 1 includes a mud distributing plate 5, which is a C-shaped plate, and the lower end of the mud distributing plate 5 is fixedly connected to the upper side wall of the rectangular feeding shell 8, and the mud distributing plate 5 is fixedly connected to a feeding channel 6, and the lower end of the feeding channel 6 is fixedly connected to a transverse tube located on the inner side of the mud distributing plate 5, and the transverse tube is fixedly connected to a plurality of discharge ports 7 extending toward the upper end, and the discharge ports 7 can spray mud on the inner wall of the mud distributing plate 5, so that the mud flows along the inner wall of the mud distributing plate 5 under the action of gravity into the interior of the rectangular feeding shell 8, and in the process of flowing, the mud will flow in a fan shape, so that the mud can fall more evenly inside the rectangular feeding shell 8, and when the mud falls more evenly inside the rectangular mud equalizing space, the two mud pushing plates 16 can squeeze the mud more quickly and evenly, so that the speed of the uniform mud can adapt to the unloading speed of the intermittent feeding mechanism 2.

[0049] The working principle of the present invention is:

[0050] When in use, feed is carried out through the feed channel 6, and the mud is sprayed on the inner wall of the mud distribution plate 5 through the discharge port 7, so that the mud flows along the inner wall of the mud distribution plate 5 under the action of gravity and enters the interior of the intermittent feeding mechanism 2 more evenly;

[0051] The intermittent feeding mechanism 2 is started to intermittently feed the mud into the rectangular mud-mixing space, and then the second electric push rod 15 is started to drive the mud-pushing plates 16 to move, so that the two mud-pushing plates 16 squeeze the mud;

[0052] During the extrusion process, the horizontal position of the corner portion can be adjusted according to the mud distribution inside the rectangular mud distribution space, so that the slope of the extrusion portion can be adjusted, so that the shape of the broken line contact surface is adapted to the mud distribution, and a larger thrust is applied to the area where the mud is more concentrated, so that the mud in this area is driven to move quickly along the width direction of the mud distribution chamber 14, and the mud is pushed to the area with less mud distribution, so that the mud is quickly pushed to be evenly distributed along the center line direction between the two mud pushing plates 16;

[0053] After the mud is homogenized, start the discharge valve plate 4 and switch it to the open state, so that the mud evenly distributed along the width direction can automatically fall into the filter press under the action of gravity, so that the mud is more evenly distributed when entering the filter press, thereby improving the extrusion efficiency of the filter press.

[0054] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
