Description

Technical Field

[0001] The invention relates to the technical field of ore washing, and specifically proposes an ore washing device for processing barite powder raw materials. Background Art

[0002] Barite, also known as barium sulfate, is a widely used industrial mineral raw material with the characteristics of high density, low solubility, chemical inertness and good heat resistance. Therefore, it has important applications in many fields. Ore washing is an important step in the processing of barite powder raw materials. It is mainly used to remove mud, clay, fine impurities, etc. from the ore raw materials, thereby improving the purity of the barite powder raw ore.

[0003] The traditional ore washing device washes the raw materials by means of rotary stirring, and the raw materials are washed by spraying water at the same time. However, it is inconvenient to take out the raw materials after washing. The muddy water generated during washing and the raw materials after washing need to be discharged from the bottom of the washing and mixing drum, and the containers for receiving the muddy water and the containers for receiving the raw materials after washing need to be replaced repeatedly, thereby reducing the efficiency and convenience of washing; and after the muddy water of the washing raw materials is discharged, another equipment is required to precipitate the muddy water, which increases the cost and tediousness of the muddy water treatment generated during the raw material washing. Summary of the invention

[0004] In view of the above problems, an embodiment of the present application provides a ore washing device for processing barite powder raw materials to solve the technical problems in the related art.

[0005] In order to achieve the above-mentioned objectives, the embodiments of the present application provide the following technical solutions: a mineral washing device for processing barite powder raw materials, comprising: a cleaning tank, a cleaning spray mechanism is arranged on the top of the cleaning tank, the inner wall of the cleaning tank is U-shaped, and a raw material collecting chamber connected to the bottom of the inner wall of the cleaning tank is provided at the middle thereof, and sedimentation chambers connected to the outer walls of both sides of the cleaning tank arranged along the width direction are provided, and the raw material collection chamber is located between the two sedimentation chambers.

[0006] A cleaning and stirring mechanism is provided in the cleaning pool; in a possible implementation, the cleaning and stirring mechanism includes two cleaning and stirring shafts rotatably connected in the cleaning pool and symmetrically arranged along the width direction thereof, and cleaning and stirring components are installed on the cleaning and stirring shafts. A gear ring is fixedly sleeved at one end of the cleaning and stirring shaft, and the two gear rings are meshed for transmission, and one of the cleaning and stirring shafts passes through the cleaning pool and is connected to an external driving source (such as a motor).

[0007] The inner wall of the cleaning pool and the inner wall of the raw material collection chamber are jointly equipped with an opening and closing mechanism for closing and opening the top of the raw material collection chamber. A conveying shaft is rotatably connected in the raw material collection chamber, and a spiral blade is installed on the conveying shaft. The inner wall of the raw material collection chamber is provided with discharge ports running through both ends of its length direction.

[0008] The sedimentation chamber is provided with an arc-shaped filter plate for filtering the raw materials in the cleaning tank, and the sedimentation chamber is also provided with a blocking mechanism for blocking the bottom of the arc-shaped filter plate.

[0009] In one possible implementation, the cleaning spray mechanism includes three branch pipes installed on the top of the cleaning pool through a support frame and arranged along the width direction of the cleaning pool. A main pipe connected to the three branch pipes is installed at one end thereof. Except for the branch pipe located in the middle having an end away from the main pipe which is open, the ends of the other two branch pipes away from the main pipe are closed, and the lower ends of the side walls of the branch pipes on both sides are installed with nozzles evenly arranged along their axial direction, and the main pipe is connected to an external water pump.

[0010] A scraper mechanism is installed in the sedimentation chamber, and the scraper mechanism includes a threaded rod rotatably connected to the inner wall of the sedimentation chamber, the threaded section of the threaded rod is located between the two inner walls in the length direction of the sedimentation chamber, a sleeve is sleeved on the threaded rod, the sleeve and the threaded rod are connected by threaded cooperation, and a scraper sliding along its axial direction is sleeved on the sleeve (a spline groove is provided on the scraper, and a connector slidingly cooperated with the spline groove is installed on the outer wall of the sleeve, and the length of the connector is less than the length of the spline groove), and the scraper is used to clean the inner wall of the sedimentation chamber, an overflow port is provided on the side of the inner wall of the sedimentation chamber away from the arc filter plate, mud discharge ports penetrating the side walls are provided at both ends of the sedimentation chamber arranged along its length direction, and valves are installed outside the mud discharge ports (not shown in the figure), and disconnection and push groups are installed on the inner walls on both sides of the sedimentation chamber arranged along its length direction.

[0011] The conveying shaft and the two threaded rods are connected through an integrated transmission group.

[0012] In one possible implementation, the disconnecting push group includes a fixed ring fixedly installed on the inner wall of the sedimentation chamber and slidably sleeved on the threaded rod, and the end face of the fixed ring away from the inner wall of the sedimentation chamber is equipped with a push ring through a telescopic tube, the outer diameter of the push ring is smaller than the outer diameter of the sleeve, and push spring rods evenly arranged along the circumference of the push ring are installed between the push ring and the fixed ring.

[0013] In one possible implementation, the threaded rod and the sleeve are both located above the lower end surface of the overflow outlet.

[0014] In a possible implementation, supplementary blocks are installed on both sides of the scraper along its width direction, the supplementary blocks have a triangular cross-section vertically cut along the axis of the threaded rod, and the side of the supplementary blocks away from the scraper is conical.

[0015] In a possible implementation manner, the opening and closing mechanism includes a connecting rod fixedly installed between two inner walls of the cleaning tank arranged along its length direction. Two blocking baffles are rotatably connected to the connecting rod. The two blocking baffles are arranged in an inverted V shape. One end of the blocking baffle away from the connecting rod abuts against the inner wall of the raw material collection cavity. A sector-shaped guide groove for slidably connecting the blocking baffle is jointly opened on the inner wall of the cleaning tank and the inner wall of the raw material collection cavity. The raw material collection cavity is also provided with a pushing drive group for driving the two blocking baffles.

[0016] In a possible implementation manner, U-shaped sealing strips are installed on the opposite surfaces of the two blocking baffles. When the blocking baffles rotate to close the top of the raw material collection cavity, the blocking baffles drive the sealing strips to abut tightly against the sector-shaped guide groove.

[0017] In a possible implementation manner, the pushing drive group includes a double-acting cylinder installed in the raw material collection cavity through a fixed seat. Plug-in guide cylinders are fixedly installed on both inner walls of the raw material collection cavity arranged along its length direction. Trapezoidal pushing heads are installed on the plug-in guide cylinders through sliding connecting rods. The two telescopic ends of the double-acting cylinder are respectively connected to the two trapezoidal pushing heads. Two wedge-shaped blocks are slidably connected to both inner walls of the raw material collection cavity arranged along its length direction. Ball bearings are rotatably connected to the wedge-shaped surfaces of the wedge-shaped blocks. The two wedge-shaped blocks are symmetrically arranged along the width direction of the raw material collection cavity. The wedge-shaped blocks cooperate with the inclined surfaces of the trapezoidal pushing heads to push the blocking baffles to rotate along the connecting rod.

[0018] In a possible implementation manner, the integrated transmission group includes installation grooves opened on both sides of the cleaning tank along its length direction. After the conveying shaft and the ends of the two threaded rods penetrate into the installation grooves, they are connected by a sprocket chain drive.

[0019] In a possible implementation manner, the blocking mechanism includes an arc-shaped storage groove opened on the inner wall of the sedimentation cavity. An arc-shaped baffle located below the arc-shaped filter plate is slidably connected to the arc-shaped storage groove. A plurality of arc-shaped racks are installed at the lower end of the arc-shaped baffle. A rotating rod is rotatably connected in the sedimentation cavity. A gear meshing and driving with the corresponding arc-shaped rack is fixedly sleeved on the rotating rod.

[0020] The above one or more technical solutions in the embodiments of the present invention have at least one of the following beneficial effects: 1. A ore washing device for processing barite powder raw materials designed by the present invention is provided with a raw material collecting chamber and two sedimentation chambers at the bottom of the cleaning tank, and the muddy water and the raw materials are discharged into the corresponding sedimentation chamber and the raw material collecting chamber respectively through the cooperation of an opening and closing mechanism, an arc-shaped filter plate and a sealing mechanism, thereby avoiding the problem of inconvenience in removing the raw materials after cleaning in traditional ore washing devices and improving the efficiency of removing the raw materials after cleaning; at the same time, the ore washing device can also directly precipitate the discharged muddy water through the sedimentation tank, thereby realizing the integrated functions of raw material cleaning and muddy water sedimentation treatment, discharge of sludge after precipitation, and transportation and discharge of raw materials after cleaning, which not only reduces the cost of muddy water sedimentation treatment, but also reduces the cumbersomeness of muddy water treatment operations.

[0021] 2. When the conveying shaft in the present invention drives the scraper to clean and scrape the sludge through the integrated transmission group, the sleeve cooperates with the threaded rod and the disconnecting and pushing group so that each time the scraper is about to approach the corresponding mud discharge port, the sleeve moves to the end of the threaded section of the threaded rod and thereby the threads on the threaded rod are disengaged; when the threaded rod rotates in the opposite direction next time, the sleeve cooperates with the threaded rod again under the pushing action of the disconnecting and pushing group, and drives the scraper to move along the length direction of the sedimentation chamber, thereby avoiding the problem that the scraper cannot move when it moves to the end of the length direction of the sedimentation chamber, causing the conveying shaft to be unable to continue rotating and thus unable to discharge all the raw materials.

[0022] 3. When the conveying shaft in the present invention drives the rotating blades to rotate to convey the cleaned raw materials, the integrated transmission group also drives the scraper mechanism to clean and discharge the sludge deposited in the sedimentation tank, thereby improving the efficiency of the coordinated work of the sludge after the raw materials are cleaned and the raw materials are discharged and conveyed.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] See also Figure 1 and Figure 3A ore washing device for processing barite powder raw materials comprises: a washing tank 1, a washing spray mechanism 2 is arranged on the top of the washing tank 1, the inner wall of the washing tank 1 is U-shaped, and a raw material collecting chamber 3 connected to the inner wall of the washing tank 1 is opened at the middle of the bottom of the inner wall, and the outer walls of both sides of the washing tank 1 arranged along the width direction are opened with sedimentation chambers 4 connected to the raw material collecting chamber 3, and the raw material collecting chamber 3 is located between the two sedimentation chambers 4.

[0036] See also Figure 1 A cleaning and stirring mechanism 5 is provided in the cleaning tank 1, and the cleaning and stirring mechanism 5 includes two cleaning and stirring shafts 50 rotatably connected in the cleaning tank 1 and symmetrically arranged along the width direction thereof, and cleaning and stirring components 51 are evenly arranged installed on the cleaning and stirring shafts 50, and a gear ring 52 is fixedly sleeved at one end of the cleaning and stirring shaft 50, and the two gear rings 52 are meshed for transmission, and one of the cleaning and stirring shafts 50 passes through the cleaning tank 1 and is connected to an external driving source (such as a motor).

[0037] See also Figure 1 and Figure 2 The inner wall of the cleaning pool 1 and the inner wall of the raw material collecting chamber 3 are jointly equipped with an opening and closing mechanism 6 for closing and opening the top of the raw material collecting chamber 3. A conveying shaft 30 is rotatably connected in the raw material collecting chamber 3, and a spiral blade 31 is installed on the conveying shaft 30. The inner wall of the raw material collecting chamber 3 is provided with a discharge port 32 running through both ends of the length direction thereof. One end of the conveying shaft 30 passes through the raw material collecting chamber 3 and is connected to an external forward and reverse motor, thereby driving the conveying shaft 30 to rotate forward and reverse.

[0038] After the raw material is cleaned, the opening and closing mechanism 6 opens the top of the raw material collecting chamber 3, and the raw material enters the raw material collecting chamber 3. The conveying shaft 30 drives the spiral blade 31 to rotate, so that the spiral blade 31 conveys the raw material to one of the discharge ports 32 according to the rotation direction of the conveying shaft 30; the opening and closing mechanism 6 cooperates with the conveying shaft 30 and the spiral blade 31, which greatly improves the convenience of discharging the raw material after cleaning.

[0039] See also Figure 1 and Figure 3 The sedimentation chamber 4 is provided with an arc-shaped filter plate 40 for filtering the raw materials in the cleaning tank 1, and the sedimentation chamber 4 is also provided with a blocking mechanism 7 for blocking the bottom of the arc-shaped filter plate 40; before the raw materials and the water transported in the cleaning spray mechanism 2 enter the cleaning tank 1, the blocking mechanism 7 blocks the arc-shaped filter plate 40, and the opening and closing mechanism 6 closes the top of the raw material collecting chamber 3, so that the raw materials and the water can stay for a period of time after entering the cleaning tank 1, and the soil on the raw materials is soaked in water, so that the raw materials and the soil are separated.

[0040] See also Figure 1The cleaning spray mechanism 2 includes three branch pipes 20 arranged along the width direction of the cleaning pool 1 and installed on the top of the cleaning pool 1 through a support frame 22. One end of the three branch pipes 20 is commonly installed with a main pipe 21 connected thereto. Except for the end of the branch pipe 20 located in the middle away from the main pipe 21, which is open, the ends of the other two branch pipes 20 away from the main pipe 21 are closed, and the lower ends of the side walls of the branch pipes 20 located on both sides are installed with nozzles evenly arranged along their axial direction. The main pipe 21 is connected to an external water pump (not shown in the figure).

[0041] A certain amount of raw materials are put into the cleaning tank 1 from the top of the cleaning tank 1 away from the main pipe 21. The branch pipe 20 in the middle flushes the raw materials with water released from its end, and can quickly release water into the cleaning tank 1. At the same time, the nozzle sprays water into the cleaning tank 1, and the external rotating drive source is started to drive the cleaning and stirring shaft 50 connected to it to rotate, so that the two cleaning and stirring shafts 50 rotate under the meshing transmission action of the ring gear 52 and stir and clean the raw materials in the water.

[0042] See also Figure 1 , Figure 2 , Figure 3 and Figure 6 The scraper mechanism 8 is installed in the sedimentation chamber 4, and the scraper mechanism 8 includes a threaded rod 80 rotatably connected to the inner wall of the sedimentation chamber 4, the threaded section of the threaded rod 80 is located between the two inner walls in the length direction of the sedimentation chamber 4, a sleeve 81 is sleeved on the threaded rod 80, and the sleeve 81 is connected to the threaded rod 80 by threaded cooperation, and a scraper 82 sliding along its axial direction is sleeved on the sleeve 81 (a spline groove is provided on the scraper 82, and a connector that slides with the spline groove is installed on the outer wall of the sleeve 81, and the length of the connector is less than the length of the spline groove). The scraper 82 is used to clean the inner wall of the sedimentation chamber 4, and an overflow port 83 is provided on the side of the inner wall of the sedimentation chamber 4 away from the arc filter plate 40, and mud discharge ports 84 penetrating the side walls of the sedimentation chamber 4 are provided at both ends arranged along the length direction thereof, and valves (not shown in the figure) are installed outside the mud discharge ports 84, and disconnection and push groups 85 are installed on the inner walls of both sides of the sedimentation chamber 4 arranged along the length direction thereof.

[0043] See also Figure 7 The conveying shaft 30 and the two threaded rods 80 are connected via an integrated transmission group 9.

[0044] In the initial state, the scraper 82 is located on one side of the sedimentation chamber 4 arranged along its length direction. When the raw material is cleaned, the opening and closing mechanism 6 opens the top of the raw material collection chamber 3, and at the same time, the valve of the mud discharge port 84 is opened, and the raw material enters the raw material collection chamber 3. The conveying shaft 30 rotates forward and drives the two threaded rods 80 to rotate through the integrated transmission group 9. The conveying shaft 30 conveys the raw material through the spiral blades 31. At the same time, the threaded rod 80 drives the sleeve 81 to move axially along the threaded rod 80 through the threaded cooperation between it and the sleeve 81. When the sleeve 81 slides until it conflicts with the scraper 82, it pushes the scraper 82 to move. The scraper 82 pushes the sludge precipitated in the sedimentation chamber 4 to move toward one of the mud discharge ports 84.

[0045] When the sludge is about to be pushed out of the sedimentation chamber 4 by the scraper 82 and approaches the corresponding mud discharge port 84, the sleeve 81 moves to the end of the threaded section of the threaded rod 80 and disengages from the thread on the threaded rod 80, and the sleeve 81 conflicts with the corresponding disconnection and push group 85. At this time, the threaded rod 80 continues to rotate with the conveying shaft 30 under the transmission action of the integrated transmission group 9, while the sleeve 81 and the scraper 82 no longer move, and the conveying shaft 30 continues to rotate, so that the conveying shaft 30 can drive the spiral blades 31 to deliver all the raw materials in the raw material collection chamber 3.

[0046] When the next batch of raw materials after cleaning needs to be transported, the external forward and reverse motor drives the conveying shaft 30 to reverse, and the conveying shaft 30 drives the threaded rod 80 to reverse through the integrated transmission group. The sleeve 81 contacts the threaded section of the threaded rod 80 under the pushing action of the disconnecting and pushing group 85, and is threadedly connected with the threaded rod 80 again as the threaded rod 80 rotates. The sleeve 81 moves to the other side of the sedimentation chamber 4 under the drive of the threaded rod 80. When the sleeve 81 and the scraper 82 are tightly pressed, the sleeve 81 drives the scraper 82 to move, so that the scraper 82 pushes the sludge again. The disconnecting and pushing group 85 cooperates with the sleeve 81, and drives the scraper 82 to move through the sleeve 81, so as to avoid the disconnecting and pushing group 85 directly pushing the scraper 82. Because there is more sludge on the other side of the scraper 82, it is difficult for the disconnecting and pushing group 85 to push the scraper 82 to contact the threaded section of the threaded rod 80 for threaded cooperation.

[0047] The conveying shaft 30, the spiral blades 31, the scraping mechanism 8 and the integrated transmission group 9 cooperate to realize the integrated conveying and discharge of the cleaned raw materials and the precipitated sludge, thereby improving the discharge efficiency of the cleaned raw materials and the precipitated sludge.

[0048] See also Figure 6The disconnecting push group 85 includes a fixed ring 850 fixedly installed on the inner wall of the sedimentation chamber 4 and slidably sleeved on the threaded rod 80. The end surface of the fixed ring 850 away from the inner wall of the sedimentation chamber 4 is installed with a push ring 851 through a telescopic tube 852. The outer diameter of the push ring 851 is smaller than the outer diameter of the sleeve 81. Between the push ring 851 and the fixed ring 850, push spring rods 853 are installed that are evenly arranged along the circumference of the push ring 851.

[0049] When the sleeve 81 is about to disengage from the end of the threaded section of the threaded rod 80, the sleeve 81 pushes the collar 851 and squeezes the push spring rod 853 and the telescopic tube 852 until the sleeve 81 is disengaged from the threaded section on the threaded rod 80 and the push spring rod 853 always remains in a retracted state; when the threaded rod 80 is reversed, the sleeve 81 contacts the end of the threaded section of the threaded rod 80 under the elastic reset action of the push spring rod 853, and engages with the thread on the threaded rod 80 again under the action of the driving force, so that the threaded rod 80 drives the sleeve 81 to move again, and when the sleeve 81 slides along the scraper 82 and contacts the scraper 82, the sleeve 81 pushes the scraper 82 to move, so that the scraper 82 can clean the sludge in the sedimentation chamber 4 again.

[0050] See also Figure 3 The threaded rod 80 and the sleeve 81 are both located above the lower end surface of the overflow port 83 to prevent the precipitated sludge from overflowing over the threaded rod 80 and entering the connection between the sleeve 81 and the scraper 82, thereby affecting the movement of the sleeve 81 and the scraper 82 driven by the threaded rod 80.

[0051] See also Figure 6 The scraper 82 is arranged along its width direction with supplementary blocks 820 installed on both sides thereof. The supplementary blocks 820 have a triangular cross-section vertically cut along the axis of the threaded rod 80, and the side of the supplementary blocks 820 away from the scraper 82 is conical. When the scraper 82 moves, the conical part of the supplementary blocks 820 pushes the sludge first to reduce resistance, thereby improving the convenience of the scraper 82 in pushing the sludge.

[0052] See also Figure 2 , Figure 4 and Figure 8 The opening and closing mechanism 6 includes a connecting rod 60 fixedly installed between two inner walls of the cleaning tank 1 arranged along its length direction. Two blocking baffles 61 are rotatably connected to the connecting rod 60. The two blocking baffles 61 are arranged in an inverted V shape to prevent water from cleaning the raw materials from accumulating in the middle of the inner wall of the cleaning tank 1 and being difficult to discharge. The end of the blocking baffle 61 away from the connecting rod 60 is in conflict with the inner wall of the raw material collecting chamber 3. The inner wall of the cleaning tank 1 and the inner wall of the raw material collecting chamber 3 are jointly provided with a fan-shaped guide groove 62 slidably connected to the blocking baffle 61. The raw material collecting chamber 3 is also equipped with a push drive group 63 for driving the two blocking baffles 61.

[0053] See also Figure 2 , Figure 4 and Figure 8 , on the opposite sides of the two plugging baffles 61, U-shaped sealing strips 610 are installed. When the plugging baffles 61 rotate to close the top of the raw material collection chamber 3, the plugging baffles 61 drive the sealing strips 610 to tightly abut against the sector-shaped guide grooves 62, thereby improving the sealing performance between the plugging baffles 61 and the sector-shaped guide grooves 62 and preventing the muddy water for cleaning the raw materials from entering the raw material collection chamber 3.

[0054] Refer to Figure 4 and Figure 8 , the top-pushing drive group 63 includes a double-acting cylinder 630 installed in the raw material collection chamber 3 through a fixing seat. On both inner walls of the raw material collection chamber 3 arranged along its length direction, plugging guide cylinders 631 are fixedly installed. On the plugging guide cylinders 631, trapezoidal pushing heads 632 are installed through sliding rods. The two telescopic ends of the double-acting cylinder 630 are respectively connected to the two trapezoidal pushing heads 632. The plugging guide cylinders 631 are in plugging fit with the rods, thus preventing the end of the rod away from the trapezoidal pushing head 632 from being suspended, which may affect the stability and supporting force of the trapezoidal pushing head 632; on both inner walls of the raw material collection chamber 3 arranged along its length direction, two wedge-shaped blocks 633 are slidably connected. On the wedge-shaped surfaces of the wedge-shaped blocks 633, balls are rotatably connected. The two wedge-shaped blocks 633 are symmetrically arranged along the width direction of the raw material collection chamber 3. The wedge-shaped blocks 633 cooperate with the inclined surfaces of the trapezoidal pushing heads 632 to push the plugging baffles 61 to rotate around the connecting rods 60.

[0055] When it is necessary to close the top of the raw material collection chamber 3, start the double-acting cylinder 630. The double-acting cylinder 630 drives the two trapezoidal pushing heads 632 to drive the rods to move towards the plugging guide cylinders 631. At the same time, the inclined surfaces of the trapezoidal pushing heads 632 are in abutting cooperation with the wedge-shaped blocks 633. The trapezoidal pushing heads 632 push the wedge-shaped blocks 633 to slide. The wedge-shaped blocks 633 push the corresponding plugging baffles 61 to rotate around the connecting rods 60 until the end of the plugging baffle 61 away from the connecting rod 60 abuts against the inner wall of the raw material collection chamber 3. At this time, the edge of the end surface of the plugging baffle 61 away from the wedge-shaped block 633 along the length direction of the plugging baffle 61 abuts tightly against the sector-shaped guide groove 62, thereby closing the top of the raw material collection chamber 3, and both of the two plugging baffles 61 are supported on both sides along their length directions, greatly improving the supporting force of the plugging baffles 61; conversely, when the double-acting cylinder 630 contracts and moves, it drives the trapezoidal pushing heads 632 to move in the direction away from the plugging guide cylinders 631. The trapezoidal pushing heads 632 no longer push and support the wedge-shaped blocks 633 and the plugging baffles 61. The plugging baffles 61 rotate under the action of their own gravity and the gravity of the raw materials, thereby opening the top of the raw material collection chamber 3. The raw materials enter the raw material collection chamber 3 and are discharged under the conveying action of the conveying shaft 30 and the spiral blades 31, greatly improving the convenience of conveying and discharging the raw materials after cleaning.

[0056] Refer to Figure 7The integrated transmission group 9 includes mounting grooves 90 provided on both sides of the cleaning tank 1 along its length direction. The conveying shaft 30 and the ends of the two threaded rods 80 are inserted into the mounting grooves 90 and connected through a sprocket chain transmission.

[0057] See also Figure 2 , Figure 3 and Figure 5 The blocking mechanism 7 includes an arc-shaped receiving groove 70 opened on the inner wall of the sedimentation chamber 4, and an arc-shaped baffle 71 located below the arc-shaped filter plate 40 is slidably connected to the arc-shaped receiving groove 70. A plurality of arc-shaped racks 72 arranged along the length direction thereof are installed at the lower end of the arc-shaped baffle 71. A rotating rod 73 is rotatably connected in the sedimentation chamber 4, and a gear 74 meshing with the corresponding arc-shaped rack 72 is fixedly sleeved on the rotating rod 73.

[0058] After the two rotating rods 73 pass through the installation groove 90, they are also connected by a sprocket chain transmission. One of the rotating rods 73 is connected to an external drive motor, thereby driving the rotating rod 73 to rotate. When the rotating rod 73 rotates, it drives the gear 74 to rotate. During the rotation process, the gear 74 drives the arc baffle 71 to slide along the arc receiving groove 70 through the meshing transmission with the corresponding arc-shaped rack 72, so that the arc baffle 71 enters the arc receiving groove 70 or moves out of the arc receiving groove 70, thereby realizing the opening and closing of the bottom of the arc filter plate 40. The blocking mechanism 7 blocks the arc filter plate 40 so that the water can stay for a period of time after the raw material and water enter the cleaning pool 1. The water soaks the soil on the raw material, so that the raw material is separated from the soil, which greatly improves the convenience and efficiency of raw material cleaning.

[0059] See also Figure 1-Figure 8 During the specific operation, the first step is to put a certain amount of raw materials into the cleaning tank 1 from the top of the cleaning tank 1 away from the side of the main pipe 21. The branch pipe 20 located in the middle flushes the raw materials with water released from its end, and can quickly release water into the cleaning tank 1. At the same time, the nozzle sprays water into the cleaning tank 1, and the external rotating drive source is started to drive the cleaning and stirring shaft 50 connected thereto to rotate, so that the two cleaning and stirring shafts 50 rotate under the meshing transmission action of the ring gear 52 and stir and clean the raw materials in the water.

[0060] In the second step, after a certain period of time, the water pump stops and the blocking mechanism 7 no longer blocks the bottom of the arc filter plate 40. The muddy water in the cleaning pool 1 enters the sedimentation chamber 4 from the arc filter plate 40. The arc filter plate 40 filters and blocks the raw materials in the cleaning pool 1. After the muddy water enters the sedimentation chamber 4, the mud in the muddy water settles in the sedimentation chamber 4, and the water in the mud is discharged from the overflow port 83, thereby pre-treating the muddy water generated after cleaning the raw materials; when the muddy water in the cleaning pool 1 is discharged, the water pump is started again, and the nozzle sprays water into the cleaning pool 1, thereby flushing the filtered raw materials, and flushing away the muddy water adhering to the raw materials again, thereby improving the cleanliness of the raw material cleaning.

[0061] In the third step, after the raw material cleaning is completed, the opening and closing mechanism 6 opens the top of the raw material collecting chamber 3, and at the same time, the valve of the mud discharge port 84 is opened, and the raw material enters the raw material collecting chamber 3. The conveying shaft 30 rotates forward and drives the two threaded rods 80 to rotate through the integrated transmission group 9. The conveying shaft 30 conveys the raw material through the spiral blades 31. At the same time, the threaded rod 80 drives the sleeve 81 to move axially along the threaded rod 80 through the threaded cooperation between it and the sleeve 81, until the sleeve 81 moves to the end of the threaded section of the threaded rod 80 and disengages from the thread on the threaded rod 80, and the sleeve 81 conflicts with the corresponding disconnection and push group 85, and the conveying shaft 30 continues to convey the raw material through the spiral blades 31 to send out all the cleaned raw materials.
