Wherein the same parts are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the drawings, and the words "bottom" and "top" "Face", "inner" and "outer" refer to directions toward or away from the geometric center of a particular part, respectively.

A mud filtering equipment, as shown in FIG. 1 , includes a frame 1, the frame 1 is connected with a filtering mechanism 2 for filtering mud, and the filtering mechanism 2 includes a filter belt 22 for separating mud and water, and two second filters for driving the filter belt 22 to rotate. A rotating roller 21 and a first motor 23 for driving the first rotating roller 21 to rotate. The two rotating rollers are both rotatably connected to the frame 1 , and the filter belt 22 is sleeved on the two first rotating rollers 21 . The first motor 23 is connected to the frame 1 using bolts, and its output shaft is coaxially welded with a first rotating roller 21 . The frame 1 is connected with an adsorption mechanism 3 for accelerating the separation of mud and water. The adsorption mechanism 3 includes a vacuum pump 31 for producing negative pressure and several vacuum pipes 32 for pumping water. The air inlet of the vacuum pump 31 is connected with the main pipe 33 by bolts, and the vacuum pipes 32 are all fixed on the side wall of the main pipe 33 with bolts, and the inner cavity thereof is communicated with the inner cavity of the main pipe 33, and its end away from the main pipe 33 is connected with the upper end of the inner wall of the filter belt 22, A drain pipe is connected to the air outlet of the vacuum pump 31 using bolts. A scraper 14 is connected to the side of the frame 1 away from the mud feeding port by bolts, and the scraper 14 can be in contact with the surface of the filter belt 22 . The mud is placed on the upper end of the filter belt 22, and then the filter belt 22 is rotated to make it move relative to the vacuum tube 32, and the vacuum tube 32 is used to speed up the speed of water passing through the filter belt 22, so that the sludge stays on the upper end of the side wall of the filter belt 22, The water is separated from the sludge by the filter belt 22, and the separated water can be reused, thereby reducing the waste of water resources. At the same time, the scraper 14 is used to separate the sludge from the filter belt 22, and then the sludge can be recycled.

As shown in FIG. 1 , since the contact area between the vacuum tube 32 and the filter belt 22 is small, the area where negative pressure is applied to the filter belt 22 is small, the flow through the filter belt 22 is small, and the speed of mud-water separation is slow. Therefore, the frame 1 is connected with an auxiliary mechanism 4 for speeding up the filtration. The auxiliary mechanism 4 is located inside the filter belt 22 and includes two second rotating rollers 41 rotatably connected to the frame 1 and a vacuum belt sleeved on the two rotating rollers. 43 and a second motor 42 that drives the rotating roller to rotate. The second motor 42 is fixed to the frame 1 using bolts, and its output shaft is coaxially welded with a second rotating roller 41 . As shown in FIG. 3 , the outer wall of the vacuum belt 43 is provided with a plurality of let-away grooves 44 parallel to the second rotating roller 41 , and the bottom surface of the let-away grooves 44 is provided with filter holes 45 . The end of the vacuum pipe 32 away from the main pipe 33 is attached to the upper end of the inner wall of the vacuum belt 43 , and its inner cavity can be communicated with the filter hole 45 . The use of the abdication groove 44 increases the area of negative pressure received by the filter belt 22, thereby increasing the volume of water passing through the filter belt 22 in the same time period, and speeding up the separation of mud and water.

As shown in FIG. 3 , after the filter hole 45 is disconnected from the vacuum tube 32 , the air pressure in the letting slot 44 remains the same as the outside air pressure, and the speed of water passing through the filter belt 22 will be slowed down at this time. Therefore, the filter holes 45 are all screwed with a one-way valve 46 , and the one-way valve 46 conducts toward the inner wall of the vacuum belt 43 . After the filter hole 45 is disconnected from the vacuum tube 32, the air will not enter the escape groove 44 from the filter hole 45. At this time, the air pressure in the escape groove 44 is still lower than the external atmospheric pressure, and the water can still be assisted by the negative pressure. down through the filter belt 22, further increasing the speed of filtration.

As shown in FIG. 3 , due to the heavy weight of the mud, the filter belt 22 and the vacuum belt 43 will bend downward due to the downward gravity exerted by the mud. A larger gap will affect the process of extracting the negative pressure from the vacant groove 44 . Therefore, both sides of the vacuum tube 32 are provided with support rollers 11 . The support rollers 11 are rotatably connected to the frame 1 , their axes coincide with the axes of the second rotating rollers 41 , and their upper ends are on the same plane as the end surface of the vacuum tube 32 . The vacuum belt 43 and the filter belt 22 are supported by the support roller 11, so that the vacuum belt 43 and the filter belt 22 will not move downward under gravity, so that the upper end of the inner wall of the vacuum belt 43 can fit the end surface of the vacuum tube 32.

In order to prevent the mud from flowing away from both sides of the filter belt 22 , as shown in FIG. The baffle ring 431 is used to restrict the flow of the mud, so that the mud does not flow away from both sides of the vacuum pump 31 .

As shown in FIG. 2, since the mud will flow away from the side of the filter belt 22 close to the first rotating roller 21, the frame 1 is rotatably connected with the first guide roller 12 and the second guide roller 13, and the first guide roller 12 side is connected with the first guide roller 12. The wall can be in contact with the upper end of the inner wall of the filter belt 22, the second guide roller 13 can be in contact with the upper end of the outer wall of the filter belt 22, and the first guide roller 12 is located on the side of the second guide roller 13 away from the auxiliary mechanism 4, and the first wire roller The upper end of the side wall is higher than the lower end of the side wall of the second guide roller 13 . The filter belt 22 is lifted up by the first wire roller, and then the second guide roller 13 is used to make the filter belt 22 closely adhere to the vacuum belt 43, thereby restricting the flow of the mud and preventing the mud from flowing away from both sides of the filter belt 22.

The escape groove 44 is blocked so that the mud does not enter the escape groove 44 . Therefore, the width of the filter belt 22 is larger than the width of the vacuum belt 43. At this time, the retaining ring 431 will exert upward supporting force on both sides of the filter belt 22, so that the two sides of the filter belt 22 will be lifted upwards. At this time, the mud cannot pass the restriction of the filter belt 22. Enter into the escape slot 44, so that the use process of the auxiliary mechanism 4 is more stable.

As shown in FIG. 3 , when the vacuum tube 32 creates a negative pressure in the escape groove 44 , the air will flow from the gap between the vacuum tube 32 and the vacuum belt 43 , which will slow down the suction of the negative pressure in the escape groove 44 at this time. speed. Therefore, a sealing ring 35 is coaxially adhered to the end face of the vacuum tube 32 away from the main pipe 33 . The use of the sealing ring 35 to reduce the gap between the vacuum tube 32 and the vacuum belt 43 reduces the volume of air passing through the gap, accelerates the vacuum tube 32 to pump negative pressure to the vacant groove 44, and increases the speed of mud-water separation.

As shown in FIG. 1 , when the scraper 14 is directly used to separate the sludge from the filter belt 22, some sludge will still remain on the surface of the filter belt 22. At this time, the residual sludge will be mixed with water when it encounters water. It drips from the surface of the filter belt 22, and this part of the sludge cannot be recovered at this time. Therefore, the side of the frame 1 connected with the scraper 14 is connected with a cleaning mechanism 5, and the cleaning mechanism 5 is located below the scraper 14. Motor 52 and several bristles 53 for cleaning the sludge. The rack 1 is connected with an installation frame 54 by bolts. The end face of the installation frame 54 close to the filter belt 22 is fixed with two L-shaped clamping blocks 55 by bolts. As shown in FIG. 5 , the cleaning motor 52 is fixedly connected to the mounting frame 54 using bolts, and its output shaft is coaxially welded with a turntable 56 , and the end face of the turntable 56 close to the filter belt 22 is welded with a cleaning rod 561 . axes do not coincide. The bristles 53 are disposed on the end surface of the cleaning seat 51 close to the filter belt 22 , and can abut against the outer wall of the filter belt 22 . The end surface of the cleaning seat 51 away from the bristles 53 is provided with a cleaning groove 511 arranged vertically and matched with the cleaning rod 561 . The cleaning rod 561 can be inserted into the cleaning groove 511 to move up and down. The cleaning motor 52 rotates to drive the turntable 56 to rotate, the turntable 56 drives the cleaning seat 51 to move back and forth, and uses the bristles 53 to clean up part of the sludge attached to the outer wall of the filter belt 22, so that more sludge falls from the outer wall of the filter belt 22. more sludge can be recycled.

In order to make the sludge more easily separated from the filter belt 22, as shown in FIG. 4, the frame 1 is also connected with two groups of vibration mechanisms 6 for vibrating the filter belt 22. The two groups of vibration mechanisms 6 are located on both sides of the filter belt 22, respectively. It includes a vibration base 61 connected with the frame 1 by bolts, two vibration wheels 62 rotatably connected with the vibration base 61 and a vibration motor 63 for driving the vibration base 61 to generate vibration. The two vibration wheels 62 jointly clamp one side of the filter belt 22 , and the two vibration wheels 62 are arranged up and down, and the vibration motor 63 is fixed to the lower end surface of the vibration seat 61 by bolts. The vibration mechanism 6 is used to vibrate the position where the filter belt 22 is in contact with the vibration wheel 62. At this time, the sludge in contact with the filter belt 22 will be subjected to the inertia exerted by itself, thereby reducing the connection strength between the sludge and the filter belt 22, so that the sludge is in contact with the filter belt 22. The separation between the mud and the filter belt 22 is easier.

As shown in FIG. 4 , since the two vibrating wheels 62 clamp the side wall of the filter belt 22 to the groove, the vibrating wheel 62 located above will exert pressure on the sludge towards the filter belt 22 at this time, thereby increasing the pressure between the filter belt 22 and the sludge. The strength of the connection between the mud. Therefore, the end face of the vibration seat 61 close to the filter belt 22 is connected with a baffle plate 64 by bolts. The scraper 14 is used to separate the sludge from the filter belt 22 , so that the vibration wheel 62 does not squeeze the sludge, so that the connection strength between the sludge and the filter belt 22 is not increased.

As shown in FIG. 4, when the scraper 14 is used to separate the sludge from the filter belt 22, the sludge will accumulate on the baffle plate 64 towards the direction of the movement of the filter belt 22. When the accumulation is too large, the sludge will fall off. This affects the recycling of sludge. Therefore, the end of the baffle 64 away from the vibrating plate is inclined toward the vibration wheel 62 , and the baffle 64 is used to guide the sludge, so that the sludge will not accumulate on the side of the baffle 64 away from the vibration wheel 62 .

As shown in FIG. 6 , since the bristles 53 are used for a long time, a large amount of sludge will remain between the bristles 53 , and the sludge cannot be separated from the filter belt 22 at this time. Therefore, the end surface of the cleaning seat 51 close to the filter belt 22 is provided with a T-shaped chute 512. The sliding groove 512 penetrates one end face of the cleaning seat 51, and the sliding groove 512 is slidably connected with the sliding block 57 matched with it, and the bristles 53 Adhesion to the end of the slider 57 close to the filter belt 22 . When the amount of sludge attached between the bristles 53 increases, the slider 57 can be separated from the cleaning seat 51, and the sludge between the bristles 53 can be cleaned at this time, so that the bristles 53 can continue to clean the dirt attached to the filter belt 22. Mud is cleaned up.

As shown in FIG. 6 , since the cleaning seat 51 will continuously reciprocate, the slider 57 will be detached from the chute 512 by the friction exerted by the filter belt 22 at this time, and the cleaning mechanism 5 cannot remove the dirt attached to the filter belt 22 at this time. Mud is cleaned up. Therefore, the cleaning seat 51 is connected with a restricting mechanism 7 that restricts the position of the slider 57 . The restricting mechanism 7 includes a restricting block 71 slidably connected to the cleaning seat 51 , two abutting blocks 72 for restricting the movement of the restricting block 71 , and a driving abutting block 72 The two abutment springs 73 move. The upper end of the cleaning seat 51 is provided with a restriction groove 513 communicating with the chute 512 , and one end of the restriction groove 513 close to the chute 512 is open. The restriction block 71 is placed in the restriction groove 513 to slide, and its lower end can abut with the lower end of the sliding groove 512 , and its end surface close to the slider 57 can abut with the slider 57 . Two opposite sides of the restricting block 71 are provided with installation grooves 711 , and the abutting block 72 slides in the installation groove 711 , and the upper end of the abutting block 72 can abut with the lower end of the sliding groove 512 without contacting the slider 57 . The contact spring 73 is placed in the mounting groove 711 , one end of the contact spring 73 is in contact with the end surface of the mounting groove 711 , and the other end is contacted with the end surface of the contact block 72 . The position of the slider 57 is restricted by the restricting block 71, and the restricting block 71 is prevented from moving when it is vibrated by the contact block 72, so that the slider 57 will not be detached from the chute 512, and the cleaning mechanism 5 will not move. The use process is more stable.

As shown in FIG. 6 , when sliding the slider 57 out of the chute 512 , it is necessary to manually move the abutment block 72 toward the installation slot 711 , and the movement of the slider 57 is troublesome at this time. Therefore, the end face of the abutting block 72 away from the limiting block 71 is provided with a wedge-shaped surface 721 . When the restriction block 71 is moved upward, a force perpendicular to the wedge-shaped surface 721 is applied to the abutment block 72 by the restriction groove 513 , so that the abutment block 72 can automatically sink into the installation groove 711 , and it is no longer necessary to manually move the abutment block 72 , so that the process of taking out the slider 57 from the chute 512 is more convenient.

As shown in FIG. 6 , when the restraining block 71 is moved upward, the restraining block 71 will be disengaged from the restraining groove 513 when the applied force is too large. This time is more troublesome. Therefore, the two sides of the restriction block 71 with the installation groove 711 are welded with anti-separation blocks 74 , and the upper end of the chute 512 is provided with an anti-separation groove 514 that communicates with the restricting groove 513 . And its lower end and the lower end surface of the restriction block 71 are in the same plane. The restraining block 71 is prevented from disengaging from the restraining groove 513 by the anti-separation block 74 , so that the use process of the restraining mechanism 7 is more stable.

As shown in FIG. 7 , when the adsorption mechanism 3 is used to pass the water through the filter belt 22 , there will still be a part of the water remaining on the upper end of the filter belt 22 , and this part of the water cannot be recovered at this time. Therefore, the upper end of the frame 1 is connected with a pressing mechanism 8 for squeezing the mud. The pressing mechanism 8 includes a pressing plate 81 connected with the frame 1 and several counterweights 82 . The end face of the pressing plate 81 facing the moving direction of the filter belt 22 is welded with a connecting rod 83 , and one end of the pressing plate 81 away from the pressing plate 81 is hinged with the frame 1 . The weights 82 are all placed on the pressing plate 81 , the lower end of which is in contact with the upper end of the pressing plate 81 , and the lower end of the pressing plate 81 is in contact with the upper end of the outer wall of the filter belt 22 . The pressing plate 81 is used to exert downward pressure on the mud, thereby accelerating the speed of water passing through the filter belt 22, so that more water can be filtered through the filter belt 22, so that more water resources can be recycled and reused .

working principle:

During operation, the mud is placed on the upper end of the filter belt 22 , and then the filter belt 22 moves continuously under the driving of the first motor 23 , and simultaneously moves the vacuum belt 43 and the filter belt 22 under the driving of the second motor 42 . When the filter hole 45 passes through the upper end of the vacuum tube 32 , since the upper end of the inner wall of the filter belt 22 is in contact with the upper end of the outer wall of the vacuum belt 43 , the vacuum tube 32 uses the filter hole 45 to draw out part of the air in the escape groove 44 to make the air pressure in the escape groove 44 Below the atmospheric pressure of the outside world, the water at the upper end of the filter belt 22 enters the abdication tank 44 through the filter belt 22 under the action of atmospheric pressure, and the filtered water is pumped out by the vacuum tube 32 . After the filter hole 45 passes through the upper end of the vacuum belt 43, the one-way valve 46 is closed so that the air pressure in the escape groove 44 is still lower than the atmospheric pressure. At this time, the water on the filter belt 22 can still enter through the filter belt 22 under the action of atmospheric pressure. When the filter belt 22 passes through the lower end of the squeeze plate 81, the squeeze plate 81 exerts downward pressure on the sludge containing water, so that more water can pass through the filter belt 22. Filtration, thereby increasing the amount of water recovered. After the sludge removes most of the water, the vibration motor 63 electrically vibrates the filter belt 22, and when the filter belt 22 passes between the two vibration wheels 62, the baffle 64 disconnects the sludge from the filter belt 22, and then the The mud moves towards the middle of the filter belt 22 under the guidance of the baffle 64, and then when the filter belt 22 passes between the two vibration wheels 62, the vibration wheel 62 drives the filter belt 22 to vibrate up and down, thereby reducing the filter belt 22 and the sludge. connection strength between. Then use the scraper 14 to scrape off most of the sludge from the filter belt 22, and then use the bristles 53 to remove part of the sludge remaining on the filter belt 22, so that less sludge remains on the filter belt 22, and more sludge is left on the filter belt 22.
