Description

Technical Field

[0001] The present application relates to the technical field of mud cleaning, and in particular to a mud recovery device. Background Art

[0002] Mud recovery devices are a series of equipment specially designed for trenchless engineering. Their main function is to separate and purify the mud generated during the construction process. Mud recovery systems usually include stone cleaning and screening, sand cleaning and screening, mud water treatment, sludge drying, etc. These devices can control the performance indicators of mud and realize the recycling of mud. Among them, after the stone is cleaned and screened, some small sand and gravel will flow into the water tank with the water flow. The impeller structure in the water tank will clean the sand again, and use the impeller bucket to lift the sand and drain it into the sand screener.

[0003] Referring to the Chinese patent with announcement number CN211664925U and the name of an automatic control device for treating polluted sediment, the pollution treatment device includes a sand washing tank, an impeller bracket and a drive system that provides power output for the impeller bracket, and blades for conveying sand and gravel are installed on the impeller bracket. When in use, mud and clean water are added to the sand washing tank, and the mud and gravel inside the sand washing tank are cleaned by a sand washer. The drive system drives the blades on the impeller bracket to rotate. When the blades rotate to the bottom of the inner side of the sand washing tank, the cleaned sand and gravel contact the inner side wall of the blade and transport it out of the sand washing tank. When cleaning and transporting the mud and gravel, the mud and gravel can be well scooped up and transported by the blades.

[0004] When the above-mentioned pollution treatment device is in use, the blades rotate driven by the impeller bracket, so that the blades shovel up the mud and sand inside the sand washing trough and transport it to the outside of the sand washing trough, but the blades are not easy to contact the edge of the sand washing trough, which easily causes the mud and sand to accumulate inside the sand washing trough. At the same time, the surface of the blades collides and rubs against the mud and sand for a long time, which will accelerate the damage to the blades. Summary of the invention

[0042] Reference Figure 1 and Figure 2 A rotating impeller 11 is installed inside the water tank 1, and a plurality of impeller buckets 12 are arranged around the rotating impeller 11. A third baffle is installed on the lower side of the opening of each impeller bucket 12. When sand and gravel fall into the impeller bucket 12, since the opening of the impeller bucket 12 faces the lower left, the third baffle can prevent the sand and gravel inside the impeller bucket 12 from falling; the rotating impeller 11 is driven by an external stepper motor, and the stepper motor can drive the impeller bucket 12 on the rotating impeller 11 to rotate in a stationary manner. A feed inlet and a water outlet are arranged on the water tank 1. External sand and gravel and water enter the water tank 1 from the feed inlet, and the water inside the water tank 1 is discharged from the water outlet.

[0043] Reference Figure 8 The support frame 2 includes a bottom plate and a cross structure. The bottom plate is a rectangular plate, and the length of the bottom plate extends in the front-back direction. The bottom plate is provided with three cross structures evenly spaced along the length direction of the bottom plate, and the cross structures are installed vertically.

[0044] Reference Figure 8 , Fig. 9 and Fig.10The conveying assembly includes a first vertical plate 21, a first limiting rod 22, a second vertical plate 23, a receiving hopper 24 and a grid plate 26. Two first vertical plates 21 are provided, which are respectively fixedly installed vertically between two adjacent cross structures. Two first limiting rods 22 are vertically installed on the rear side walls of the first vertical plates 21. The first limiting rods 22 limit the sliding direction of the conveying assembly. A second vertical plate 23 parallel to the first vertical plate 21 is slidably installed on the first limiting rod 22. The second vertical plate 23 is provided with a second through slot sleeved on the first limiting rod 22. A receiving hopper 24 is fixedly installed on the second vertical plate 23. The receiving hopper 24 is provided with a material leakage hole 25. A grid plate 26 is installed on the receiving hopper 24.

[0045] Reference Figure 2 , Figure 8 and Fig. 9 The receiving hopper 24 includes a bottom plate, a leakage plate and two side plates. One end of the bottom plate is connected to the upper end of the second vertical plate 23, and the other end is connected to the lower end of the leakage plate. The bottom plate gradually tilts downward along the direction from the second vertical plate 23 to the rotating impeller 11. One end of the leakage plate is connected to the corresponding end of the bottom plate, and the other end is tilted upward. The leakage plate and the bottom plate are roughly vertically arranged. The leakage plate is provided with leakage holes 25, which are arranged as rectangular holes distributed horizontally. The holes on the grid plate 26 are of the same size as the leakage holes 25; the grid plate 26 is slidably mounted on the inner side wall of the leakage plate.

[0046] When in use, the receiving hopper 24 and the second vertical plate 23 move upward along the first limit rod 22 driven by the first conveying member 4, and the grating plate 26 moves upward synchronously with the receiving hopper 24 and moves downward relatively under the constraint of the inner plate of the impeller bucket 12, so that the holes on the grating plate 26 are misaligned or overlapped with the leakage holes 25, and the sand and gravel in the receiving hopper 24 are transported to the inside of the impeller bucket 12.

[0047] Reference Figure 2 , Figure 5 and Fig. 9 The support member 3 includes a support plate 31, a shuttle column 32, a first spring 33 and a pressing block 34. The support plate 31 is set as an L-shaped support plate 31, and the L-shaped support plate 31 includes a vertical right-angle plate and a horizontal right-angle plate. The extension direction of the vertical right-angle plate is parallel to the leakage plate of the receiving hopper 24, and the extension direction of the horizontal right-angle plate is parallel to the bottom plate of the receiving hopper 24. The upper end of the vertical right-angle plate of the support plate 31 is fixedly set on the bottom of the receiving hopper 24, the upper end of the shuttle column 32 is fixedly installed on the bottom of the grid plate 26, and the lower end is penetrated and set on the horizontal right-angle plate of the support plate 31 and can slide relative to the horizontal right-angle plate. The first spring 33 is arranged around the shuttle column 32; the bottom of the grid plate 26 is penetrated and set on the bottom plate of the receiving hopper 24, one end of the first spring 33 is connected to the bottom of the grid plate 26, and the other end is connected to the horizontal right-angle plate of the L-shaped support plate 31.

[0048] Rectangular grooves are vertically opened on the two side plates of the receiving hopper 24, and a pressing block 34 is fixedly installed on the grid plate 26, and the pressing block 34 is arranged through the rectangular groove; the sum of the distances on the left and right sides of the outer side of the receiving hopper 24 is smaller than the sum of the distances on the left and right sides of the inner side of the impeller bucket 12, and the pressing block 34 is longer and contacts the plate at the edge of the impeller bucket 12 during the process of following the grid plate 26 and the receiving hopper 24 to rise.

[0049] When in use, the leakage hole 25 on the receiving hopper 24 coincides with the hole on the grid plate 26, and the sand and gravel inside the receiving hopper 24 falls into the impeller bucket 12. When the grid plate 26 and the receiving hopper 24 move upward to above the third baffle plate simultaneously, the pressing block 34 contacts the plate inside the impeller bucket 12, and the receiving hopper 24 continues to move upward, and the pressing block 34 on the grid plate 26 is stopped by the plate inside the impeller bucket 12 and stops moving upward until the leakage hole 25 on the receiving hopper 24 coincides with the hole on the grid plate 26, and the receiving hopper 24 stops moving upward, and the sand and gravel inside the receiving hopper 24 falls into the impeller bucket 12; at this time, the receiving hopper 24 and the rotating impeller 11 are both in a stationary state, and the pushing block 41 is in contact with the pushing plate 43.

[0050] After the sand and gravel inside the receiving hopper 24 falls into the impeller bucket 12, the rotating impeller 11 and the pushing block 41 start to rotate driven by the stepper motor driver. After the pushing block 41 is separated from the pushing plate 43, the rotating impeller 11 stops rotating. When the receiving hopper 24 is reset, the rotating impeller 11 rotates again.

[0051] When the pushing block 41 is separated from the pushing plate 43, the receiving hopper 24 begins to reset downward and in the process of resetting, as the receiving hopper 24 moves downward, the pressing block 34 remains relatively still and gradually breaks away from the restraint of the inner plate of the impeller bucket 12. The first spring 33 gradually extends from the compressed state to restore the elastic force, and the leakage hole 25 is staggered with the hole on the grid plate 26. When the spring fully restores the elastic force, the receiving hopper 24 drives the grid plate 26 to move downward synchronously, and the pressing block 34 breaks away from the inner plate of the impeller bucket 12.

[0052] Reference Figure 2 , Figure 7 and Fig.11The first transmission member 4 includes a sliding rod 42, a push plate 43, a hydraulic connector 44, a first connecting rod 45, a second connecting rod 46, an auxiliary plate 451, a base 461 and a clamping plate 462. The push block 41 is fixedly mounted on the impeller bucket 12, the sliding rod 42 is arranged in the water tank 1 for horizontal sliding, a push plate 43 is fixedly mounted on one end of the sliding rod 42, and the push block 41 is used to drive the push plate 43 to slide horizontally; the hydraulic connector 44 is mounted just below the receiving hopper 24 and just above the sliding rod 42, and a first connecting rod 45 for horizontal movement and a second connecting rod 46 for vertical movement are mounted on the hydraulic connector 44; an auxiliary plate 451 is fixedly mounted on the first connecting rod 45, and the two ends of the auxiliary plate 451 are fixedly connected to the sliding rod 42 and the first connecting rod 45 respectively; while the first connecting rod 45 moves horizontally, the power of the hydraulic oil inside the hydraulic connector 44 can push the second connecting rod 46 to move vertically upward.

[0053] A base 461 is fixedly installed on the top of the second connecting rod 46, and the base 461 consists of a square seat and a columnar seat. The square seat is fixedly installed on the top of the second connecting rod 46, and columnar seats are symmetrically installed on the front and rear sides of the square seat. The two columnar seats extend forward and backward respectively. Two front and rear clamping plates 462 are fixedly installed on the bottom plate of the receiving hopper 24 close to the second vertical plate 23. The two clamping plates 462 extend to the left and right, and a transversely extending rectangular groove is penetrated on the clamping plate 462. The two columnar seats are respectively penetrated on the two rectangular grooves. The setting of the rectangular groove facilitates the columnar seat on the base 461 to slide back and forth in the rectangular groove, so as to make the receiving hopper 24 slide upward along the direction of the first limit rod 22.

[0054] When in use, the first transmission member 4 drives the receiving hopper 24 to move up and down. The external driving member drives the rotating impeller 11 to rotate, and the impeller bucket 12 rotates accordingly. When the push block 41 at the bottom of the impeller bucket 12 contacts the push plate 43, the push block 41 continues to rotate under the drive of the impeller bucket 12 and drives the push plate 43 and the sliding rod 42 to slide; at the same time, the auxiliary plate 451 fixedly connected to the sliding rod 42 drives the first connecting rod 45 to push into the hydraulic communicating vessel 44, and the hydraulic oil inside the hydraulic communicating vessel 44 drives the second connecting rod 46 to move upward, and then the base 461 at the top of the second connecting rod 46 drives the clamping plate 462 and the receiving hopper 24 to slide upward along the first limiting rod 22.

[0055] Reference Figure 6 and Figure 7The second transmission member 5 includes a limit plate 55, a sliding block 52, a support rod 53 and a second spring 54. One end of the sliding rod 42 is connected to a limit plate 55 distributed laterally, and a limit slot 51 is provided on the limit plate 55. The sliding rod 42 is inserted into and slides in the limit slot 51. The sliding block 52 located in the limit slot 51 is fixedly mounted on the sliding rod 42. A second spring 54 is provided between the inner wall of the limit slot 51 and the sliding block 52, and the second spring 54 is sleeved on the sliding rod 42. The top of the sliding block 52 is hinged with a support rod 53.

[0056] Reference Figure 4 The cleaning assembly 6 includes a cleaning plate 61, a flushing hole 62, a transition plate 63, a gauze 64 and a second baffle 65. The bottom of the cleaning plate 61 is installed obliquely from top to bottom toward the direction of the feed inlet of the receiving hopper 24, the upper end of the cleaning plate 61 is sleeved in the water tank 1, and a plurality of flushing holes 62 are opened on the cleaning plate 61. The transition plate 63 is installed on the front side wall of the support frame 2, and the transition plate 63 is arranged obliquely downward toward the direction of the receiving hopper 24;

[0057] Reference Figure 4 and Figure 7 One end of the support rod 53 is hinged to the rear side of the cleaning plate 61. When the hinged end of the support rod 53 and the sliding block 52 slides back and forth in the limiting slide groove 51, the hinged end of the support rod 53 and the cleaning plate 61 can drive the cleaning plate 61 to rotate back and forth.

[0058] A gauze screen 64 is connected between the cleaning plate 61 and the transition plate 63 , and a second baffle plate 65 is fixedly installed in the water tank 1 and is located between the cleaning plate 61 and the rotating impeller 11 .

[0059] When in use, the second transmission member 5 drives the cleaning plate 61 to make an arc-shaped lifting motion to wash the sand and gravel on the cleaning plate 61. When the sliding rod 42 slides, the sliding block 52 moves on the limiting slide groove 51 and the sliding rod, and the support rod 53 moves synchronously with the hinged end of the sliding block 52, so that the cleaning plate 61 is lifted. At this time, the water inside the water tank 1 is squeezed by the cleaning plate 61 and passes through the flushing hole 62 on the cleaning plate 61, so that the water flow emitted from the flushing hole 62 washes the sand and gravel on the cleaning plate 61; when the pushing block 41 is separated from the pushing plate 43, the sliding block 52 drives the support rod 53 to return to its original position, the cleaning plate 61 rotates and resets, and the water flow formed at the flushing hole 62 washes the sand and gravel again.

[0060] In this embodiment, the driving member acts on the rotating impeller 11, the first connecting member and the second connecting member at the same time when the power is output. The output source of the driving member drives the rotating impeller 11 to rotate, and the impeller bucket 12 on the rotating impeller 11 rotates accordingly. When the pushing block 41 at the top of the impeller bucket 12 contacts the pushing plate 43, the movement of the sliding rod 42 can simultaneously drive the power source output of the first transmission member 4 and the second transmission member 5, which can save costs. While realizing the driving function, it effectively utilizes energy and reduces unnecessary energy loss. At the same time, under the action of the hydraulic connecting device 44 and the second spring 54, the first transmission member 4 and the second transmission member 5 can have good reset properties.

[0061] In this embodiment, a first vertical plate 21 is slidably connected to the support frame 2, and a second vertical plate 23 is vertically slidably installed on the first limiting rod 22. The limiting rod and the groove are used to make them slidably connected. In other embodiments, the bearing connection or the sliding spacer connection can be used to make them slidably connected.

[0062] The implementation principle of a mud recovery device in the embodiment of the present application is:

[0063] First, water and sand and gravel enter the water tank 1 through the feed port, and the rotating impeller 11 rotates slowly driven by the external motor. When the pushing block 41 on the impeller bucket 12 contacts the pushing plate 43 on the sliding rod 42, the sliding rod 42 moves to the left, and the first connecting rod 45 extends to the left into the hydraulic communicating vessel 44, pushing the hydraulic oil inside the hydraulic communicating vessel 44, causing the second connecting rod 46 connected to the hydraulic communicating vessel 44 to drive the receiving hopper 24 to move up and down; when the sliding rod 42 moves to the left, it drives the sliding block 52 to move to the left on the limiting slide groove 51 and the sliding rod, pushing one end of the support rod 53 to slide, and the other end of the support rod 53 drives the cleaning plate 61 to rotate around the axis at the top of the cleaning plate 61, so that the cleaning plate 61 is lifted; when the pushing block 41 and the sliding rod 42 are disengaged, the cleaning plate 61 and the receiving hopper 24 are reset.

[0064] When the receiving hopper 24 is transferred to the upper front side of the impeller bucket 12 and the third baffle by the first conveying member 4, the receiving hopper 24 continues to move upward, and the inner plate on the rotating impeller 11 contacts the pressing block 34, so that the hole on the grid plate 26 coincides with the leakage hole 25, and the sand and gravel in the receiving hopper 24 falls into the impeller bucket 12. At this time, the pushing block 41 and the pushing plate 43 are still in contact and in a stationary state, and the rotating impeller 11 stops rotating; when the sand and gravel completely fall into the impeller bucket 12, the pushing block 41 is separated from the pushing plate 43, and the receiving hopper 24 is separated from the restraint of the first conveying member 4 and resets downward.

[0065] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
