[0028] See Figure 1 and Figure 2 The present invention provides a conveying device, comprising a conveying assembly 1 and a separation assembly 2. The conveying assembly 1 comprises a conveying member 11 and a driving member 12. The driving member 12 is connected to the conveying member 11 and is used to drive the material to move along the feeding direction. The separation assembly 2 comprises a chute 21 and a water guide trough 22. The input end of the chute 21 is arranged at the output end of the conveying member 11. The output end of the chute 21 is arranged vertically. The input end of the water guide trough 22 is connected to the side wall of the output end of the chute 21. The chute 21 is connected to the water guide trough 22, and the output end of the chute 21 is arranged at an angle to the input end of the water guide trough 22. It should be noted that the material is solid impurities containing water, the conveying member 11 is a spiral blade arranged obliquely upward, and the feeding direction is the direction from bottom to top of the spiral blade.

[0029] In this way, when the material containing moisture falls vertically through the chute 21, since the material can move downward along the side wall of the chute 21 connecting to the water guide trough 22, and due to the different surface tensions of solids and liquids on the inner wall of the pipe, the moisture in the material can flow into the inside of the water guide trough 22 under the action of surface tension, and the solid components in the material fall vertically under the action of gravity, thereby reducing the moisture content of the material and avoiding the high moisture content of the material and reducing the efficiency of subsequent processing.

[0030] It can be understood that the angle between the input end of the water guide groove 22 and the output end of the chute 21 can be flexibly adjusted according to actual needs and the discharge speed of the output end of the conveying member 11. In this embodiment, the angle between the input end of the water guide groove 22 and the output end of the chute 21 is an acute angle, which facilitates the flow of liquid in the water guide groove 22.

[0031] See Figure 1 In some embodiments, the conveying assembly 1 further includes a shell 13, and the conveying member 11 is disposed inside the shell 13. In this embodiment, the length of the spiral blade is parallel to the length direction of the shell 13, the driving member 12 is a motor, and the output end of the motor is fixedly connected to one end of the spiral blade facing the output end of the shell 13 to drive the spiral blade to rotate and convey materials, and the motor is fixedly connected to the end of the shell 13; the output end of the shell 13 is tilted upward, and the side wall of the output end of the shell 13 is provided with a hole (not shown in the figure) that is connected to the chute 21, so that the conveying member 11 conveys the material through the output end of the shell 13 to the inside of the chute 21, and discharges it vertically to the outside through the output end of the chute 21, and the input end of the water guide trough 22 is tilted downward.

[0032] In this way, the driving member 12 drives the spiral blade to rotate, so that the spiral blade drives the material to move along the feeding direction, and falls into the chute 21 through the output end of the shell 13. By controlling the conveying speed of the material, the material can be conveyed along the inner wall of the chute 21. During the process, the liquid inside the material flows into the water guide groove 22 under the action of surface tension, thereby reducing the water content of the material, achieving material reduction, facilitating subsequent processing, and reducing disposal costs.

[0033] It can be understood that the conveying member 11 can also be a feeding mechanism such as a conveyor belt. The transportation of water-containing materials is an existing technology. The specific structure of the conveying member 11 and the driving member 12 can be flexibly adjusted according to actual needs, and can realize inclined transportation of materials and make the materials fall vertically from the inside of the shell 13. No more examples are given here.

[0034] See Figure 1 In some embodiments, the chute 21 includes a first guide portion 211 and a first conveying portion 212 that are interconnected. One end of the first guide portion 211 is connected to the output end of the shell 13 and is in communication with the shell 13, and the other end is connected to the first conveying portion 212. The first conveying portion 212 is vertically arranged. The input end of the chute 21 is arranged at the end of the first guide portion 211 away from the first conveying portion 212, and the output end of the chute 21 is arranged at the end of the first conveying portion 212 away from the first guide portion 211. That is, the material is transported to the first guide portion 211 and the first conveying portion 212 at one time through the output end of the shell 13, and is discharged to the outside through the first conveying portion 212. The water guide trough 22 is connected to the side wall of the first conveying portion 212.

[0035] The length direction of the first guide portion 211 is perpendicular to the feeding direction, the first guide portion 211 is fixedly connected to the shell 13 , and the input end of the water guide trough 22 is fixedly connected to the side wall of the first conveying portion 212 .

[0036] In this way, the material is transported to the inside of the first guide part 211 through the output end of the shell 13, and can be transported along the inner wall of the first guide part 211 to the inner wall of the first conveying part 212 under the guidance of the inclined first guide part 211, so that the material can always remain connected with the inner wall of the chute 21, thereby allowing more liquid to enter the water guide trough 22 under the action of surface tension, thereby improving the efficiency of solid-liquid separation and reducing the water content of the material output by the desander, making it easier to continue to process the material and reduce disposal costs.

[0037] It can be understood that the first guide part 211 can also be detachably connected to the shell 13 by bolts, flanges and other structures. Similarly, the input end of the water guide groove 22 can also be detachably connected to the side wall of the first conveying part 212 by bolts, flanges and other structures. In this embodiment, the first guide part 211 is fixedly connected to the shell 13, and the first conveying part 212 is fixedly connected to the input end of the water guide groove 22. This is to improve the sealing performance of the connection between the first guide part 211 and the shell 13 and the connection between the first conveying part 212 and the water guide groove 22 to avoid leakage.

[0038] See Figure 1 In some embodiments, the water channel 22 includes a second guide portion 221 and a second conveying portion 222 , wherein one end of the second guide portion 221 is connected to the first conveying portion 212 , and the other end is connected to the second conveying portion 222 , and the second guide portion 221 is arranged at an angle to the first conveying portion 212 .

[0039] In this embodiment, the end of the second guide part 221 connected to the first conveying part 212 is the input end of the water guide trough 22, and the end of the second conveying part 222 away from the second guide part 221 is the output end of the water guide trough 22. The length direction of the second guide part 221 is parallel to the feeding direction.

[0040] In this way, the second guide part 221 is tilted downward, which can guide the liquid in the material to flow to the second conveying part 222 under the action of its own gravity, and be transported to the outside through the second conveying part 222, thereby improving the efficiency of solid-liquid separation, so that the material with some liquid removed and the removed liquid can be transported in the chute 21 and the water guide trough 22 respectively, reducing the water content of the material, achieving a reduction in the amount of material output by the desander, and reducing the pressure of subsequent material processing.

[0041] It can be understood that the extending directions of the second conveying portion 222 and the second guiding portion 221 can be adjusted according to actual needs. In this embodiment, the second conveying portion 222 and the second guiding portion 221 are arranged at an obtuse angle.

[0042] See Figure 1 In some embodiments, the end of the second conveying portion 222 away from the second guiding portion 221 is vertically arranged, that is, the output end of the water guide trough 22 is vertically arranged.

[0043] In this way, the liquid gradually converges and flows into the second conveying part 222 under the action of the second guide part 221. The vertical arrangement of the second conveying part 222 not only facilitates the flow of liquid to the outside, but also saves the space occupied by the conveying device, making the overall structure more compact.

[0044] It is understandable that the second guiding portion 221 may also be coaxially arranged with the second conveying portion 222 and is not limited to being arranged vertically, which will not be elaborated herein.

[0045] See Figure 1 In some embodiments, the thickness of the second guide portion 221 is less than the thickness of the second conveying portion 222. In this embodiment, the second conveying portion 222 is a circular tube structure, and the thickness of the second conveying portion 222 is also the diameter of the second conveying portion 222.

[0046] In this way, since the liquid flows through the inner wall of the first conveying part 212 to the inner wall of the second guide part 221 under the action of surface tension, the flow rate of the liquid in the second guide part 221 is small, and it is not easy to cause blockage, etc., and a smaller width can be set to save space and reduce the moisture content of the material.

[0047] It is understandable that the specific sizes and specifications of the second guiding portion 221 and the second conveying portion 222 can also be flexibly adjusted according to actual needs, and this embodiment does not limit this.

[0048] See Figure 2 In some embodiments, the water channel 22 further includes a second transition portion 223, the ends of which are connected to the second guide portion 221 and the second conveying portion 222, respectively. The width of the second transition portion 223 gradually decreases toward the second conveying portion 222. In this embodiment, the ends of the second transition portion 223 are fixedly connected to the second guide portion 221 and the second conveying portion 222, respectively.

[0049] In this way, the width of the second transition portion 223 gradually decreases, which can converge the liquid and make it flow quickly into the second conveying portion 222, thereby improving the solid-liquid separation efficiency and reducing the water content of the material, thereby reducing the amount of material output by the desander and facilitating subsequent processing.

[0050] See Figure 1 In some embodiments, the extension direction of the second conveying portion 222 is parallel to the extension direction of the first conveying portion 212 , that is, the first conveying portion 212 and the second conveying portion 222 are both vertically arranged, and the extension direction of the first guide portion 211 is perpendicular to the extension direction of the second guide portion 221 .

[0051] In this way, the vertically arranged first conveying portion 212 and the second conveying portion 222 can respectively convey the material after partial moisture removal and the separated liquid, so as to improve the feeding efficiency.

[0052] It is understandable that the extension direction of the second conveying portion 222 may also be different from the extension direction of the first conveying portion 212, as long as it can achieve the transportation of materials and liquids, and no further details are given here.

[0053] See Figure 1 and Figure 2The present invention further provides a desander, comprising a desander body (not shown) and a conveying device connected to the desander body. In this embodiment, the input end of the housing 13 is connected to the desander body, so that the material separated by the desander body enters the interior of the housing 13 through the input end of the housing 13.

[0054] Furthermore, the desander further includes a tank body 3, and the water guide trough 22 is connected to the tank body 3. In this embodiment, the output end of the water guide trough 22 is connected to a connector 32, and the end of the connector 32 facing away from the water guide trough 22 is connected to the tank body 3 through a connecting pipe 31, so that the liquid separated from the material enters the interior of the tank body 3 through the connecting pipe 31.

[0055] In this way, the liquid separated from the material flows back to the tank body 3 through the connecting pipe 31, the solid material in the tank body 3 can settle under the action of gravity, and the liquid material can be discharged to the outside through overflow drainage, thereby improving the solid-liquid separation efficiency of the material and facilitating subsequent processing.

[0056] It can be understood that the types of the connecting piece 32 and the connecting pipe 31 can be adjusted according to actual needs. In this embodiment, the connecting piece 32 is a pagoda joint and the connecting pipe 31 is a transparent hose, which is convenient for observing the liquid flow state and can be maintained in time when the connecting pipe 31 is blocked.

[0057] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
