Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mineral separation, and in particular relates to a self-cleaning heavy medium separation tank. Background Art
[0002] Gravity separation is a separation technology based on the principle that materials of different densities settle at different rates in a medium. In a heavy medium environment, a suspension with a density higher than water is used as the separation medium, causing materials with a lower density than the medium to float and materials with a higher density to sink, thus achieving the purpose of separation.
[0003] Conventional heavy medium separation tanks have several limitations. Specifically, the material generated during the separation process tends to settle at the bottom of the tank, requiring regular downtime for cleaning, which impacts production efficiency. Therefore, it is necessary to design a self-cleaning heavy medium separation tank that can automatically remove the waste deposited at the bottom of the tank. This system can be used for efficient separation in mineral processing and recycling, primarily for separating solid particles of varying densities, particularly in the cleaning, grading, and concentrating of materials such as coal and ore. Utility Model Content
[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a self-cleaning heavy medium separation tank.
[0005] In order to solve the above technical problems, the utility model provides a self-cleaning heavy medium sorting trough, including a sorting trough body, a synchronous pulley, a synchronous belt, a cleaning strip, a servo motor and a partition. There is a discharge port at the upper right edge of the sorting trough body, and the discharge path of the discharge port is inclined to the lower right. Two synchronous pulleys are rotatably provided on the sorting trough body, one of which is located at the inner bottom of the sorting trough body, and the other is located at the discharge port of the sorting trough body. An inclined synchronous belt is provided for transmission between the two synchronous pulleys, and the outer ring of the synchronous belt is connected to a circle of cleaning strips. A servo motor is installed on the sorting trough body, and the output shaft of the servo motor is connected to the synchronous pulley located at the bottom of the sorting trough body. A partition is connected to the sorting trough body, and the partition separates the upper part of the sorting trough body into sorting space and discharge space. The synchronous belt and the cleaning strip are both located in the discharge space of the sorting trough body.
[0006] Preferably, a screen frame is also included, and the cleaning strip is provided with the screen frame.
[0007] Preferably, a bottom plate is also included. The inner bottom of the sorting trough is provided with a bottom plate. The upper side of the bottom plate is tilted downward and is arranged close to the synchronous pulley below, so as to be suitable for guiding the material at the bottom of the sorting trough to the synchronous pulley below.
[0008] Preferably, it also includes a feeding chute wheel and a gear. The feeding chute wheel is rotatably provided on the discharge port of the sorting chute body. The front end of the feeding chute wheel and the front end of the upper synchronous pulley are both connected with gears, and the two gears are meshed.
[0009] Preferably, a baffle is further included. The sorting trough body is slidably provided with a baffle located below the partition plate, and the baffle is suitable for contacting and cooperating with the bottom plate.
[0010] Preferably, a lifting cylinder and a sliding frame are further included. The lifting cylinder is installed on the sorting trough body, and the sliding frame is connected between the piston rod of the lifting cylinder and the baffle.
[0011] On the basis of overcoming the shortcomings of the prior art, the utility model can achieve the following beneficial effects:
[0012] 1. The synchronous belt brings the material at the bottom of the sorting trough to the discharge port of the sorting trough through the cleaning strip.

DETAILED DESCRIPTION
[0021] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
[0022] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The technical solutions of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.
[0023] A self-cleaning heavy medium separation tank, such as Figure 1-Figure 3 As shown, it includes a sorting trough body 1, a synchronous pulley 21, a synchronous belt 22, a cleaning strip 23, a servo motor 24 and a partition 12. There is a discharge port at the upper right edge of the sorting trough body 1, and the discharge path of the discharge port is inclined to the lower right. Two synchronous pulleys 21 are rotatably provided on the sorting trough body 1, one of which is located at the inner bottom of the sorting trough body 1, and the other synchronous pulley 21 is located at the discharge port of the sorting trough body 1. An inclined synchronous belt 22 is transmitted between the two synchronous pulleys 21, and the outer ring of the synchronous belt 22 is connected to a circle of cleaning strip 23. A servo motor 24 is installed on the sorting trough body 1, and the output shaft of the servo motor 24 is connected to the synchronous pulley 21 located at the inner bottom of the sorting trough body 1. When performing gravity sorting operation, materials with a density higher than the medium will fall to the inner bottom of the sorting trough body 1, and the materials at the inner bottom of the sorting trough body 1 will be supported between the synchronous belt 22 and the cleaning strip 23. The servo motor is controlled The synchronous pulley 24 drives the synchronous belt 22 to rotate clockwise, so that the synchronous belt 22 brings the material at the bottom of the sorting trough body 1 to the discharge port of the sorting trough body 1 through the cleaning strip 23. When the cleaning strip 23 gradually rotates to the lower side of the synchronous belt 22, the material will fall under the action of gravity and be discharged from the discharge port of the sorting trough body 1, thereby realizing the self-cleaning function, eliminating the steps of manual cleaning and regular shutdown for cleaning. A partition 12 is connected to the sorting trough body 1, and the partition 12 divides the upper part of the sorting trough body 1 into a sorting space and a discharge space. The synchronous belt 22 and the cleaning strip 23 are both located in the discharge space of the sorting trough body 1. When gravity sorting is performed, most of the materials with a lower density than the medium will float above the sorting space of the sorting trough body 1, and the materials with a lower density than the medium will be blocked by the partition 12, thereby preventing the synchronous belt 22 and the cleaning strip 23 from accidentally discharging the materials with a lower density than the medium, thereby improving the accuracy of self-cleaning.
[0024] like Figure 4 As shown, a screen frame is also included. The cleaning strip 23 is provided with a screen frame, and the liquid medium on the cleaning strip 23 is fully discharged through the screen frame, thereby retaining the solid medium that needs to be discharged.
[0025] like Figure 2 As shown, a bottom plate 11 is provided at the inner bottom of the sorting trough body 1. The upper side of the bottom plate 11 is tilted downward and is arranged close to the synchronous pulley 21 below, so as to be suitable for guiding the material at the bottom of the sorting trough body 1 to the synchronous pulley 21 below. The material falling to the bottom of the sorting trough body 1 will flow along the bottom plate 11 to between the synchronous belt 22 and the cleaning strip 23 on the synchronous pulley 21 below, thereby improving the self-cleaning effect and efficiency.
[0026] like Figure 1 、 Figure 2 and Figure 5 As shown, it also includes a discharge trough wheel 31 and a gear 32. The discharge port of the sorting trough body 1 is rotatably provided with a discharge trough wheel 31. The front end of the discharge trough wheel 31 and the front end of the upper synchronous pulley 21 are both connected with a gear 32. The two gears 32 are engaged with each other, so that when the synchronous pulley 21 rotates clockwise, the discharge trough wheel 31 is driven to rotate counterclockwise through the engagement of the gear 32, and the discharge trough wheel 31 will drive the material on the discharge port to be discharged intermittently.
[0027] like Figure 2 and Figure 6 As shown, a baffle 41 is also included. The baffle 41 is slidably provided on the sorting trough body 1 and is located below the partition 12. The baffle 41 is suitable for contacting and cooperating with the bottom plate 11. Initially, the baffle 41 blocks the bottom plate 11 and completely separates the sorting space and the discharge space. The material on the bottom plate 11 cannot flow into the synchronous pulley 21 and the cleaning strip 23 temporarily. When the sorting operation is carried out for a certain time and the particles with a density lower than the medium and the particles with a density greater than the medium are separated, the baffle 41 is moved up and opened, so that the particles with a density greater than the medium on the bottom plate 11 flow to the synchronous pulley 21 and the cleaning strip 23 for discharge.
[0028] like Figure 2 and Figure 6 As shown, it also includes a lifting cylinder 42 and a sliding frame 43. The lifting cylinder 42 is installed on the sorting trough body 1, and the sliding frame 43 is connected between the piston rod of the lifting cylinder 42 and the baffle 41. The lifting cylinder 42 is controlled to drive the sliding frame 43 to drive the baffle 41 to move up and down, thereby automatically controlling the baffle 41, and the degree of automation is high.
[0029] Obviously, the embodiments described above are only part of the embodiments of the present invention, rather than all of the embodiments. They only express the preferred implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention.
[0030] It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, they can also make several modifications, increases and decreases in quantity, improvements and substitutions. Therefore, based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.
