Description

Technical Field

[0001] The utility model belongs to the field of mechanical equipment, and particularly relates to a novel hopper for unloading bulk granular materials. Background Art

[0002] When the material conveying equipment operates normally, when the material passes through the feeding port, too much material surging into the material pipe will increase the conveying pressure of the material pipe. After a period of time, the material pipe will be blocked. Existing anti-blocking and dredging devices generally adopt dredgers and manual dredging methods. Dredgers have the disadvantages of occupying a large effective space, being difficult to adjust, maintain and replace. Manual dredging not only has a large labor intensity, but also causes the entire conveying equipment to stop due to the blockage of the feeding equipment, resulting in waste of energy and manpower. Therefore, a hopper device that can reduce the conveying pressure of the material pipe and prevent the material pipe from being blocked is needed. Content of the Utility Model

[0003] The purpose of the utility model is to provide a novel hopper for unloading bulk granular materials to solve the problems existing in the prior art. To achieve the above invention purpose, the technical solution adopted by the utility model is as follows:

[0004] A novel hopper for unloading bulk granular materials includes a hopper. An air inlet device for loosening materials is sleeved outside the hopper. A butterfly valve and a material pipe are fixedly connected to the bottom of the hopper. A material poking device for dredging the material pipe is obliquely arranged at the upper part of the material pipe. The material is conveyed to a storage point after passing through the hopper and into the material pipe.

[0005] Further, the hopper includes a cylindrical section and a conical section. The top of the conical section is fixedly connected to the bottom of the cylindrical section. The bottom of the conical section is fixedly connected to the butterfly valve. The air inlet device includes an air inlet device one and an air inlet device two. The air inlet device one is sleeved outside the cylindrical section. The air inlet device two is sleeved outside the conical section.

[0006] Further, the air inlet device one includes two symmetrically arranged semi-ring bodies one. The semi-ring body one includes a semi-circular outer shell one in a semi-circular shape. A semi-circular nozzle one in a semi-circular shape is arranged on the inner side of the semi-circular outer shell one in a ring shape. The semi-circular nozzle one communicates with the inner cavity of the semi-circular outer shell one. An air inlet one is arranged on the outer side of the semi-circular outer shell one in a ring shape. The air inlet one communicates with the inner cavity of the semi-circular outer shell one and an air inlet pipe. A plurality of through holes one communicating with the semi-circular nozzle one are arranged on the circumference of the cylindrical section. Flanges one are arranged at both ends of the semi-circular outer shell one. The two semi-circular outer shells one are connected to each other through threaded through holes on the flanges one.

[0007] Further, the second intake device includes two symmetrically arranged semi-ring bodies II. Each semi-ring body II includes a semi-circular outer shell II in a semi-circular shape. Inside the circular inner side of the semi-circular outer shell II, there is a semi-circular nozzle II in a semi-circular shape. On the circular inner side of the semi-circular outer shell II, there is a semi-circular inclined surface that fits the outer surface of the conical section. The lower ring section of the semi-circular inclined surface is connected to the semi-circular nozzle II. The semi-circular nozzle II communicates with the inner cavity of the semi-circular outer shell II. On the circular outer side of the semi-circular outer shell II, there is an air inlet II, and the air inlet II communicates the inner cavity of the semi-circular outer shell II with the intake pipe. On the circumference of the conical section, there are multiple through holes II that communicate with the semi-circular nozzle II. At both ends of the semi-circular outer shell II, there are flanges II, and the two semi-circular outer shells II are connected to each other through the threaded through holes on the flanges II.

[0008] Further, the material poking device includes a housing, a bracket, a rotating structure, and a reciprocating structure. The rotating structure includes a motor, a fixed block, and a turntable. The motor is fixedly arranged on the side of the housing, and the output end of the motor is fixedly connected to the center position of one side of the turntable arranged inside the housing cavity. On the other side of the turntable, there is a fixed block, and the fixed block is slidably connected to the reciprocating structure. Inside the housing cavity, two brackets are fixedly arranged, and the turntable is arranged between the two brackets.

[0009] Further, the reciprocating structure includes a movable groove, a first sliding rod, and a second sliding rod. Through holes III are arranged on the central axes at both ends of the housing, and through holes IV are arranged on the two brackets. The through holes III and the through holes IV are on the same axis. A group of adjacent through holes III and through holes IV slidably connect the first sliding rod, and another group of through holes III and through holes IV slidably connect the second sliding rod. The ends of the first sliding rod and the second sliding rod located inside the housing cavity are respectively fixedly connected to both ends of the movable groove.

[0013] 2. The material poking device is provided. When the material poking device works inside the material pipe, it moves up and down, driving the materials to move up and down inside the material pipe to create a falling space to prevent the materials from blocking inside the material pipe.

[0020] As Figure 1 shown, a new type of hopper for unloading bulk granular materials includes a hopper. The granular materials enter the hopper through the top of the hopper. An air inlet device for loosening the materials is sleeved outside the hopper. The air inlet device continuously conveys compressed air into the hopper, continuously blows the granular materials to make the materials looser to ensure the fluidity of the materials and prevent the particulate matters from sticking to the hopper wall. The bottom of the hopper is fixedly connected to a butterfly valve 6 and a material pipe 7. The butterfly valve 6 is used to open / close the channel. When the materials do not need to be conveyed, the butterfly valve 6 is closed to prevent foreign matters from entering the material pipe 7. An upper part of the material pipe 7 is inclined and provided with a material poking device 8 for dredging the material pipe 7. The output end of the material poking device slides up and down to continuously stir the granular materials to prevent the materials from being blocked in the material pipe 7. The materials are conveyed to the storage point after passing through the hopper and into the material pipe 7.

[0021] As Figure 1 shown, the hopper includes a cylindrical section 1 and a conical section 4. The bottom of the cylindrical section 1 fixes the top of the conical section 4. The bottom of the conical section 4 is fixedly connected to the butterfly valve 6. The air inlet device includes an air inlet device one 2 and an air inlet device two 5. The air inlet device one 2 is sleeved outside the cylindrical section 1, and the air inlet device two 5 is sleeved outside the conical section 4.

[0022] As shown Figure 3 in the figure, the intake device 2 includes two symmetrically arranged semi-ring bodies 1. Each semi-ring body 1 includes a semi-circular outer shell 202 in a semi-circular shape. Inside the inner ring of the semi-circular outer shell 202, there is a semi-circular nozzle 203 in a semi-circular shape. The semi-circular nozzle 203 communicates with the inner cavity of the semi-circular outer shell 202. On the outer ring of the semi-circular outer shell 202, there is an air inlet 201. The air inlet 201 communicates the inner cavity of the semi-circular outer shell 202 with the intake pipe 3. On the circumference of the cylindrical section 1, there are multiple through holes 1 communicating with the semi-circular nozzle 203. At both ends of the semi-circular outer shell 202, there are flanges 204. The two semi-circular outer shells 202 are connected to each other through the threaded through holes 205 on the flanges 204. An air compressor (not shown in the figure) passes compressed air into the inner cavity of the semi-circular outer shell 202 through the intake pipe 3. The compressed air in the inner cavity of the semi-circular outer shell 202 is passed into the through holes 1 on the circumference through the semi-circular nozzle 203. The compressed air contacts the granular material inside the cylindrical section 1, making the granular material loose (i.e., the gap increases) to ensure the fluidity of the material. The material continues to flow downward and then contacts the compressed air in the conical section 4. It should be noted that the inner ring of the semi-circular outer shell 202 is in close contact with the cylindrical section 1 to ensure airtightness (however, the airtight effect of the fit is not very ideal in the actual process). Therefore, in order to enhance airtightness, two suitable sealing rings can be provided on the upper and lower sides of the semi-circular nozzle 203 to increase the airtightness between the semi-circular nozzle 203 and the cylindrical section 1. The sealing rings on the upper and lower sides of the semi-circular nozzle 203 are attached to the corresponding upper and lower sides of the through holes 1, ensuring that the compressed air coming from the inner cavity only passes into the cylindrical section 1 through the through holes 1. In addition, sealing rings can also be provided on the flanges 204 to increase airtightness. Regarding the setting of the sealing rings, the same can be done for the intake device 5, which will not be elaborated below. It should be noted that since the intake device 2 is formed by screwing two semi-ring bodies 1 through the flanges 204, that is, the inner cavities of the two semi-ring bodies 1 are connected, the air inlet 201 on the semi-circular nozzle 203 can be set on only one side, that is, the air inlet 201 is only provided on one of the semi-circular nozzles 203.

[0023] As shown Figure 4As shown, the intake device two 5 includes two symmetrically arranged semi-ring bodies two. The semi-ring body two includes a semi-circular outer shell two 502 in a semi-circular shape. Inside the semi-circular outer shell two 502, there is a semi-circular nozzle two 504 in a semi-circular shape. Inside the semi-circular outer shell two 502, there is a semi-circular inclined surface 503 that fits the outer surface of the conical section 4. The lower ring section of the semi-circular inclined surface 503 is connected to the semi-circular nozzle two 504. The semi-circular nozzle two 504 communicates with the inner cavity of the semi-circular outer shell two 502. On the outer side of the semi-circular outer shell two 502, there is an air inlet two 501. The air inlet two 501 communicates the inner cavity of the semi-circular outer shell two 502 and the intake pipe 3. On the circumferential direction of the conical section 4, there are multiple through holes two that communicate with the semi-circular nozzle two 504. At both ends of the semi-circular outer shell two 502, there are flanges two 506. The two semi-circular outer shells two 502 are connected to each other through the threaded through holes 507 on the flanges two 506. The precautions and connection methods of each component of the semi-circular outer shell two 502 are the same as those above. In addition, the difference is that the semi-circular inclined surface 503 should be adapted to the inclination angle of the conical section 4 as much as possible. If a sealing ring is provided on the semi-circular nozzle two 504, then there is no need to consider the fitting of the semi-circular inclined surface 503 to the conical section 4 anymore.

[0024] As Figure 1 , 2As shown, the material poking device 8 includes a housing 801, a bracket 804, a rotating structure, and a reciprocating structure; the rotating structure includes a motor 9, a fixed block 806, and a turntable 802. The motor 9 is fixedly provided on the side of the housing. The output end of the motor 9 is fixedly connected to the center position of one side of the turntable 802 disposed in the inner cavity of the housing 801. A fixed block 806 is provided on the other side of the turntable 802. The fixed block 806 is slidably connected to the reciprocating structure. Two brackets 804 are fixedly provided in the inner cavity of the housing 801, and the turntable 802 is provided between the two brackets 804. The reciprocating structure includes a movable groove 805, a first slide bar 803, and a second slide bar 807. Through holes three are provided on the central axes at both ends of the housing 801, and through holes four are provided on the two brackets 804. The through holes three and the through holes four are on the same axis. A group of adjacent through holes three and through holes four slidably connect the first slide bar 803, and another group of through holes three and through holes four slidably connect the second slide bar 807. One ends of the first slide bar 803 and the second slide bar 807 located in the inner cavity of the housing 801 are respectively fixedly connected to both ends of the movable groove 805. A through groove 8051 is provided on the movable groove 805, and the through groove 8051 and the fixed block 806 are in sliding fit. The output end of the motor 9 rotates to drive the turntable 802 to rotate. The rotation of the turntable 802 drives the fixed block 806 thereon to rotate around the center of the turntable 802. Since the first slide bar 803 and the second slide bar 804 of the reciprocating structure are in sliding fit with the through holes three and the through holes four, the reciprocating structure can move left and right on the plane as shown in Figure 2 . And the fixed block 806 is slidably fitted with the movable groove 805. So when the sliding block 806 rotates, the horizontal movement will be transmitted to the reciprocating structure, that is, the rotation of the sliding block 806 will drive the reciprocating structure to move left and right. If it rotates clockwise, when the fixed block 806 is at the position as shown in Figure 2 , it will drive the reciprocating structure to move right, and when it rotates 180°, it will drive the reciprocating structure to move left. It should be noted that the closer the position of the fixed block 806 is to the edge of the turntable 802 and the larger the turntable 802 is, the farther the reciprocating distance of the reciprocating structure will be. Therefore, the fixed block 806 cannot be set at the center position of the turntable 802 (at this time the reciprocating structure will not displace). In this way, those skilled in the art can set the size of the turntable 802 and the position of the fixed block 806 according to specific requirements. In addition, it should also be noted that the length from the parts of the first slide bar 803 and the second slide bar 807 located outside the housing 801 to the bracket 804 (the bracket close to the corresponding through hole three) needs to be greater than the radius of the turntable 802 to prevent the first slide bar 803 and the second slide bar 807 from slipping out of the through hole three.

[0025] As Figure 2 shown, a plurality of ramming rods 808 are provided on the circumference of one end of the second sliding rod 807 outside the housing 801, and one end of the second sliding rod 807 outside the housing 801 is located inside the material pipe 7. The ramming rod 808 is used to increase the contact area with the material, so that the material ramming operation is more smooth.

[0026] Workflow: Turn on the air compressor (not shown, connected to the input end of the air inlet pipe 3), turn on the motor 9, open the butterfly valve 6, feed the material into the top of the hopper, and the material is transferred to the storage point after passing through the top of the hopper and into the material pipe 7. Among them, compressed air is fed into the hopper through the air inlet device to loosen the material, and the material ramming device 8 operates in the material pipe 7 to prevent the material from clogging.

[0027] The embodiments described above are only descriptions of the preferred modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, variations, modifications, and substitutions made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
