[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0027] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" 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 an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0029] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0030] This embodiment provides a material conveying device, which can realize the conveying of materials from a low place to a high place, and can screen out dust in the materials during the conveying process to ensure the cleanliness of the materials, thereby ensuring the use effect of the materials.

[0031] like Figure 1 As shown, the material conveying equipment includes a frame 10 and a screw feeding assembly 20 arranged on the frame 10. The screw feeding assembly is tilted as a whole to realize the conveying of materials from a low place to a high place. Among them, the screw feeding assembly 20 includes a barrel 21, a conveying shaft 22 and a dust filter 23. The barrel 21 is tilted, and a feeding port 211 is arranged at the bottom end of the barrel 21, and a discharge port 212 is arranged at the top end of the barrel 21. A dust outlet arranged downward is arranged on the outer peripheral wall of the barrel 21; the conveying shaft 22 is rotatably arranged in the barrel 21, and the conveying shaft 22 is used to convey the material from the feeding port 211 to the discharge port 212. The conveying shaft 22 includes a rotating shaft 221 and blades 222 extending spirally along the outer peripheral wall of the rotating shaft 221; the dust filter 23 is arranged at the dust outlet.

[0032] In this embodiment, the barrel 21 is tilted, one end of the barrel 21 provided with the feeding port 211 is low in height, and one end of the barrel 21 provided with the discharge port 212 is high in height, and the conveying shaft 22 is rotatably provided in the barrel 21, and the conveying shaft 22 includes a spirally extending blade 222. When the conveying shaft 22 rotates, the blade 222 can push the material from one end of the feeding port 211 of the barrel 21 to the other end provided with the discharge port 212, thereby realizing the transmission of the material. By tilting the barrel 21, it is not necessary for the staff to set up a scaffold, nor is it necessary for the staff to carry the bagged materials to the scaffold and then dump them, which is conducive to reducing labor costs, improving feeding efficiency, avoiding safety hazards such as materials spilling and causing the staff to step on and slip, and ensuring operation safety.

[0033] As the material is pushed upward by the blades 222, the dust in the material will be separated. Since the dust particles in the material are small, the dust in the material will pass through the dust filter 23 and be discharged from the barrel 21 through the dust outlet, thereby ensuring the cleanliness of the material and improving the use effect of the material. The material is blocked by the dust filter 23 and continues to stay in the barrel 21, so that it can be transported to the designated position through the discharge port 212 under the action of the blades 222, thereby improving the utilization rate of the material.

[0034] In order to avoid interference between the conveying shaft 22 and the barrel 21, a gap is provided between the blades 222 in the conveying shaft 22 and the inner wall of the barrel 21. The gap is small, which can prevent the blades 222 from contacting the barrel 21 during the rotation of the conveying shaft 22, and can prevent the material from getting stuck in the gap between the blades 222 and the barrel 21, thereby ensuring the smooth delivery of the material.

[0035] In this embodiment, the pore size of the filter holes on the dust filter 23 is 0.5 mm-1.5 mm, so as to screen out dust and intercept materials to prevent the materials from passing through the dust filter 23, thereby avoiding waste of materials. Exemplarily, the pore size of the filter holes on the dust filter 23 can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm or 1.5 mm.

[0036] In order to improve the dust filtering effect, the dust outlet is arranged close to the feeding port 211. That is, along the axial direction of the barrel 21, the distance between the dust outlet and the feeding port 211 is smaller than the distance between the dust outlet and the discharge port 212. During the material conveying process, because the dust particles are small, the driving effect of the blades 222 on the dust is poor, and the dust will gather at the bottom of the barrel 21. By arranging the dust outlet close to the feeding port 211, the dust gathered at the bottom of the barrel 21 can be discharged smoothly through the dust outlet.

[0037] In order to ensure the cleanliness of the material put into the barrel 21, a feed filter 24 is provided in the feed port 211. The feed filter 24 is used to perform preliminary filtering on the material entering the barrel 21, and can filter out larger particles of impurities in the material to prevent the larger particles of impurities from entering the barrel 21 and being unable to be screened out; in addition, the feed filter 24 can also separate the staff from the blades 222 in the barrel 21, and protect the staff from touching the working blades 222 and getting injured.

[0038] Optionally, the mesh number of the feed filter 24 is smaller than the mesh number of the dust filter 23. Larger particles of impurities will be blocked by the feed filter 24 and will not enter the barrel 21; the material can enter the barrel 21 through the feed filter hole, and the particle diameter of the material is larger than the aperture of the filter hole of the dust filter 23, so it is blocked by the dust filter 23, ensuring that the material can be conveyed under the action of the conveying shaft 22; the dust can pass through the dust filter 23 and be discharged from the barrel 21 to ensure the cleanliness of the material.

[0039] As the amount of material in the barrel 21 decreases, some material may accumulate in the barrel 21 and cannot be transferred to the discharge port 212. To facilitate the discharge of this part of the material, a discharge port 213 with an opening facing downward is provided at the bottom of the barrel 21. A valve assembly is provided at the discharge port 213, and the valve assembly is used to selectively open or close the discharge port 213. When the material is being transferred, the discharge port 213 is in a closed state; when the material transfer is completed, the discharge port 213 is opened, and the remaining material in the barrel 21 will be discharged from the discharge port 213 under the action of gravity, so as to avoid the material remaining in the barrel 21 for a long time, resulting in material waste.

[0040] like Figure 1As shown, the spiral feeding assembly 20 also includes a motor 25, and both ends of the conveying shaft 22 are rotatably connected to the barrel 21 through positioning bearings, and one end of the conveying shaft 22 close to the feeding port 211 extends out of the barrel 21 and is transmission-connected to the motor 25. After the motor 25 is started, it drives the conveying shaft 22 to rotate to realize the conveying of materials.

[0041] The motor 25 is located at the lower end of the barrel 21, which lowers the center of gravity of the spiral feeding assembly 20 and makes the material conveying equipment more stable.

[0042] The frame 10 includes a base 11 and a mounting frame arranged on the base 11 , and the barrel 21 is arranged on the mounting frame. The barrel 21 is supported by the mounting frame so that the barrel 21 can be arranged tilted.

[0043] In order to adjust the height of the discharge port 212 as required, the mounting frame can adjust the inclination angle of the barrel 21 to adjust the material conveying height as required.

[0044] Specifically, the mounting frame includes two brackets arranged at an interval, the top end of each bracket is movably connected to the barrel 21, and the height of at least one bracket is adjustable. The inclination angle of the barrel 21 is adjusted by adjusting the height of the bracket.

[0045] For ease of understanding, the two brackets are respectively a first bracket 121 and a second bracket 122. The first bracket 121 is a fixed bracket, which is fixedly arranged on the base 11 and has a fixed height. The top of the first bracket 121 is hinged to the barrel 21 to support the barrel 21, and the first bracket 121 is arranged near the feeding port 211; the second bracket 122 is a liftable bracket, which is fixedly arranged on the base 11, and the top of the second bracket 122 can abut against the barrel 21, and the second bracket 122 is arranged near the discharge port 212. By adjusting the height of the second bracket 122, the inclination angle of the barrel 21 is adjusted.

[0046] Illustratively, when the height of the second bracket 122 becomes smaller, the height of one end of the barrel 21 where the discharge port 212 is provided is lowered, and the overall inclination angle of the barrel 21 becomes smaller; when the height of the second bracket 122 becomes larger, the height of one end of the barrel 21 where the discharge port 212 is provided is increased, and the overall inclination angle of the barrel 21 becomes larger.

[0047] To avoid interference between the top of the second bracket 122 and the barrel 21 , the top of the second bracket 122 includes a rotatably connected arc-shaped support plate, the curvature of the support plate matches the curvature of the outer wall of the barrel 21 , and the support plate is used to support the barrel 21 .

[0048] To improve the supporting effect of the support plate on the barrel 21, the support plate can be detachably connected to the barrel 21. For example, after the support plate carries the barrel 21, it can be connected to the barrel 21 through fasteners such as screws, or the support plate and the barrel 21 can be fixed by magnetic adsorption.

[0049] Optionally, the second bracket 122 may include a lower bracket and an upper bracket that are slidably connected, the bottom end of the lower bracket is fixed to the base 11, the upper bracket is slidably connected to the lower bracket in the vertical direction, and the top end of the upper bracket is rotatably connected to a support plate, which is used to support the barrel 21. The upper bracket and the lower bracket may be fixed by a fastening assembly to fix the upper bracket at a suitable position of the lower bracket, thereby adjusting the height of the second bracket 122.

[0050] Optionally, the fastening assembly may include a pin or a screw, a first mounting hole is provided on the upper bracket, at least two second mounting holes are arranged at intervals along the height direction on the lower bracket, and the pin or the screw is provided in the first mounting hole. When the upper bracket slides to a suitable position relative to the lower bracket, the pin or the screw cooperates with the second mounting hole at a corresponding position on the lower bracket, thereby fixing the upper bracket and the lower bracket.

[0051] In other embodiments, the second bracket 122 may include a gear rack assembly, a screw nut assembly, a linear motor 25, a cylinder or a hydraulic cylinder, and other linear transmission components capable of outputting linear motion. The output end of the linear transmission component is connected to the barrel 21.

[0052] In some embodiments, the mounting frame includes two brackets arranged at intervals, the heights of the two brackets are different, and along the arrangement direction of the two brackets, the position of at least one of the two brackets is adjustable, so that by adjusting the distance between the two brackets, the inclination angle of the barrel 21 can be adjusted. The top end of each bracket supports the barrel 21 through a rotatably connected support plate.

[0053] Optionally, the mounting frame further comprises a driving assembly, which is connected to at least one of the brackets to drive the bracket connected thereto to move along the arrangement direction of the two brackets, thereby adjusting the spacing between the two brackets. Optionally, the driving assembly can be a component capable of outputting linear motion, such as a gear rack assembly, a lead screw nut assembly, a linear motor 25, a cylinder or a hydraulic cylinder.

[0054] In order to facilitate adjustment of the position of the material conveying device so as to transfer materials as required, at least two running wheels 13 are rotatably connected to the bottom surface of the base 11 to facilitate the movement of the material conveying device.

[0055] The present embodiment also provides a dryer, including a tank body and the above-mentioned material conveying device, wherein the discharge port 212 of the material conveying device is connected to the inlet at the top of the tank body so as to convey materials such as molecular sieves and alumina from a low place to a high place, thereby realizing automatic feeding, saving labor costs and time, and preventing materials from spilling and causing workers to slip and fall.

[0056] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
