[0002] Existing rotary valves mostly use flat blade structures. During unloading, materials tend to bridge and accumulate between the blades and the chamber, causing blockages. Furthermore, the blades wear out quickly due to direct friction with the inner wall of the chamber. In addition, traditional wear-resistant parts are mostly fixed structures, making maintenance and replacement inconvenient. It is difficult to meet the requirements of long-term stable operation while ensuring both anti-blocking and wear resistance.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Example 1

[0018] Please see Figures 1 to 5 This utility model provides a technical solution: an anti-clogging and wear-resistant unloader, including a material passage shell 1, a drive device 2 fixedly installed on one side of the material passage shell 1, a material passage cavity is provided inside the material passage shell 1, and an inlet and an outlet are respectively connected to the top and bottom of the material passage cavity. Maintenance ports are provided through the inner walls on both sides of the material passage cavity, and a sealing cover can be detachably connected to each maintenance port. The output shaft of the drive device 2 extends into the material passage cavity through a through hole opened on the surface of the sealing cover on the corresponding side and is fixedly fitted with an impeller. The impeller includes a sleeve part 101, which is fixedly fitted on the output shaft of the drive device 2. A number of uniformly distributed, ring-shaped, staggered blades 102 are provided around the outer wall of the sleeve part 101. Each staggered blade 102 includes two flat plate segments, which are staggered at an angle in the axial direction of the output shaft of the drive device 2. An arc-shaped connecting section is provided between the opposite ends of the two flat plate segments.

[0019] The outer casing 1 is made of cast steel, and the internal material passage chamber is a chamber structure adapted to the impeller rotation. The drive device 2 is a geared motor, which provides power for the impeller rotation. Maintenance ports are opened on both sides of the inner wall of the material passage chamber for easy inspection or cleaning of the internal components. The sealing cover is made of wear-resistant sealing material and can tightly cover the maintenance port to prevent material leakage. The impeller's sleeve part 101 is a cast steel hub structure that can be firmly fixed on the output shaft of the drive device 2. The drop-type staggered blades 102 are made of wear-resistant alloy material. The two flat plate sections are arranged at an angle to each other along the axial direction of the output shaft of the drive device 2. The arc-shaped connecting section between the opposite ends of the two flat plate sections is a smooth arc structure, so that the adjacent drop-type staggered blades 102 cooperate with the inner wall of the material passage chamber to form a staggered drop chamber, which can effectively break the material bridging and accumulation, reduce the clogging that is prone to occur in flat plate blades, and at the same time, the arc-shaped connecting section can guide the material to slide down the slope, improving the smoothness of unloading.

[0020] Furthermore, a wear-resistant end strip 103 is detachably installed on the side of the drop-type staggered blade 102 facing the inner wall of the material passage cavity, and the outer edge of the wear-resistant end strip 103 contacts the inner wall of the material passage cavity.

[0021] The wear-resistant end strip 103 is made of hard alloy material and is detachably installed on the side of the offset blade 102 facing the inner wall of the material passage cavity. Its outer edge can keep in close contact with the inner wall of the material passage cavity. During the rotation of the impeller, the wear-resistant end strip 103 can not only replace the offset blade 102 to directly contact the inner wall of the material passage cavity, reducing the wear of the blade, but also scrape off the material adhering to the inner wall of the material passage cavity, further improving the anti-clogging effect.

[0022] Furthermore, the bottom edge of the outer side of the wear-resistant end bar 103 is set as an arc-shaped bottom edge 104, and the top edge of the outer side of the wear-resistant end bar 103 contacts the inner wall of the material passage cavity.

[0023] The arc-shaped bottom edge 104 of the wear-resistant end strip 103 is an arc-shaped structure integrally formed with the wear-resistant end strip 103. The material is the same as that of the wear-resistant end strip 103. The arc-shaped bottom edge 104 can effectively reduce the contact area between the outer end of the wear-resistant end strip 103 and the inner wall of the material passage cavity, reduce the friction and wear between the two, and adapt to the arc-shaped structure of the inner wall of the material passage cavity to ensure stable contact with the inner wall. Compared with the flat edge, the arc-shaped bottom edge 104 can reduce the possibility of jamming with the material at the feed inlet.

[0024] Furthermore, grooves are provided at both ends of the inner bottom surface of the wear-resistant end bar 103, and insertion holes 105 are provided on the inner wall of each groove near the side of the differential staggered blade 102. Two threaded holes 106 corresponding to the insertion holes 105 are provided at both ends of the outer end face of the differential staggered blade 102. A fastener 107 is inserted into each insertion hole 105, and one end of each fastener 107 is threaded into the corresponding threaded hole 106.

[0025] The grooves at both ends of the inner bottom surface of the wear-resistant end strip 103 are groove structures adapted for the installation of fasteners 107. The insertion hole 105 is opened on the inner wall of the groove near the side of the drop-type staggered blade 102. The threaded hole 106 on the outer end face of the drop-type staggered blade 102 is correspondingly set with the insertion hole 105. The fastener 107 is a countersunk head bolt made of high-strength wear-resistant steel, which can pass through the insertion hole 105 and be threaded into the threaded hole 106, so as to achieve a stable connection between the wear-resistant end strip 103 and the drop-type staggered blade 102. At the same time, this structure facilitates the installation, removal, maintenance and replacement of the wear-resistant end strip 103 after wear.

[0026] Example 2

[0027] Please see Figures 1 to 5 This utility model provides a technical solution: an anti-clogging and wear-resistant unloader, including a material passage shell 1, a drive device 2 fixedly installed on one side of the material passage shell 1, a material passage cavity is provided inside the material passage shell 1, and an inlet and an outlet are respectively connected to the top and bottom of the material passage cavity. Maintenance ports are provided through the inner walls on both sides of the material passage cavity, and a sealing cover can be detachably connected to each maintenance port. The output shaft of the drive device 2 extends into the material passage cavity through a through hole opened on the surface of the sealing cover on the corresponding side and is fixedly fitted with an impeller. The impeller includes a sleeve part 101, which is fixedly fitted on the output shaft of the drive device 2. A number of uniformly distributed, ring-shaped, staggered blades 102 are provided on the outer wall of the sleeve part 101. Each staggered blade 102 includes two flat plate segments, which are staggered at an angle in the axial direction of the output shaft of the drive device 2. An arc-shaped connecting section is provided between the opposite ends of the two flat plate segments.

[0028] The outer casing 1 is made of cast steel, and the internal material passage chamber is a chamber structure adapted to the impeller rotation. The drive device 2 is a geared motor, which provides power for the impeller rotation. Maintenance ports are opened on both sides of the inner wall of the material passage chamber for easy inspection or cleaning of the internal components. The sealing cover is made of wear-resistant sealing material and can tightly cover the maintenance port to prevent material leakage. The impeller's sleeve part 101 is a cast steel hub structure that can be firmly fixed on the output shaft of the drive device 2. The drop-type staggered blades 102 are made of wear-resistant alloy material. The two flat plate sections are arranged at an angle to each other along the axial direction of the output shaft of the drive device 2. The arc-shaped connecting section between the opposite ends of the two flat plate sections is a smooth arc structure, so that the adjacent drop-type staggered blades 102 cooperate with the inner wall of the material passage chamber to form a staggered drop chamber, which can effectively break the material bridging and accumulation, reduce the clogging that is prone to occur in flat plate blades, and at the same time, the arc-shaped connecting section can guide the material to slide down the slope, improving the smoothness of unloading.

[0029] Furthermore, a wear-resistant end strip 103 is detachably installed on the side of the drop-type staggered blade 102 facing the inner wall of the material passage cavity, and the outer edge of the wear-resistant end strip 103 contacts the inner wall of the material passage cavity.

[0030] The wear-resistant end strip 103 is made of hard alloy material and is detachably installed on the side of the offset blade 102 facing the inner wall of the material passage cavity. Its outer edge can keep in close contact with the inner wall of the material passage cavity. During the rotation of the impeller, the wear-resistant end strip 103 can not only replace the offset blade 102 to directly contact the inner wall of the material passage cavity, reducing the wear of the blade, but also scrape off the material adhering to the inner wall of the material passage cavity, further improving the anti-clogging effect.

[0031] Furthermore, the bottom edge of the outer side of the wear-resistant end bar 103 is set as an arc-shaped bottom edge 104, and the top edge of the outer side of the wear-resistant end bar 103 contacts the inner wall of the material passage cavity.

[0032] The arc-shaped bottom edge 104 of the wear-resistant end strip 103 is an arc-shaped structure integrally formed with the wear-resistant end strip 103. The material is the same as that of the wear-resistant end strip 103. The arc-shaped bottom edge 104 can effectively reduce the contact area between the outer end of the wear-resistant end strip 103 and the inner wall of the material passage cavity, reduce the friction and wear between the two, and adapt to the arc-shaped structure of the inner wall of the material passage cavity to ensure stable contact with the inner wall. Compared with the flat edge, the arc-shaped bottom edge 104 can reduce the possibility of jamming with the material at the feed inlet.

[0033] Furthermore, grooves are provided at both ends of the inner bottom surface of the wear-resistant end bar 103, and insertion holes 105 are provided on the inner wall of each groove near the side of the differential staggered blade 102. Two threaded holes 106 corresponding to the insertion holes 105 are provided at both ends of the outer end face of the differential staggered blade 102. A fastener 107 is inserted into each insertion hole 105, and one end of each fastener 107 is threaded into the corresponding threaded hole 106.

[0034] The grooves at both ends of the inner bottom surface of the wear-resistant end strip 103 are groove structures adapted for the installation of fasteners 107. The insertion hole 105 is opened on the inner wall of the groove near the side of the drop-type staggered blade 102. The threaded hole 106 on the outer end face of the drop-type staggered blade 102 is correspondingly set with the insertion hole 105. The fastener 107 is a countersunk head bolt made of high-strength wear-resistant steel, which can pass through the insertion hole 105 and be threaded into the threaded hole 106, so as to achieve a stable connection between the wear-resistant end strip 103 and the drop-type staggered blade 102. At the same time, this structure facilitates the installation, removal, maintenance and replacement of the wear-resistant end strip 103 after wear.

[0035] Furthermore, a feed hopper 108 is integrally installed inside the feed inlet. The feed hopper 108 has a stepped, gradually tapering structure from top to bottom, and the stepped, gradually tapering structure includes three continuously connected inclined inner walls.

[0036] The feed hopper 108 is integrally formed with the feed housing 1. Its stepped, tapering structure includes three continuously connected inclined inner walls, which can guide the material into the feed chamber in layers, avoiding the material from accumulating at the feed inlet and forming bridging. At the same time, the inclined inner walls can be sprayed with an anti-stick and wear-resistant coating to further reduce the probability of material adhesion and blockage.

[0037] Furthermore, a discharge hopper 109 is integrally provided inside the discharge port. The bottom end of the discharge hopper 109 is a vertically extending cylindrical structure, and several spiral guide plates 110 are evenly distributed in a ring around its inner wall.

[0038] The discharge hopper 109 is integrally formed with the material passage shell 1. Its cylindrical structure at the bottom can expand the discharge channel space. The spiral guide plate 110 on the inner wall is made of wear-resistant alloy material and is evenly distributed in a ring. During the material unloading process, the spiral guide plate 110 can guide the material to slide down along its surface, replacing the material's free fall accumulation method, effectively avoiding the narrowing and blockage at the discharge port, and improving the discharge efficiency.

[0039] Furthermore, the top of the opposite inner walls on both sides of the material passage cavity is an arc-shaped structure with a radius corresponding to the width of the drop-type staggered blade 102, and the bottom end is a discharge slope 111 extending towards the discharge port.

[0040] The arc-shaped structures on the top of the inner walls on both sides of the material passage chamber have radii that match the width of the drop-type staggered blades 102, ensuring smooth impeller rotation. The discharge ramp 111 at the bottom is an inclined structure extending towards the discharge port, and a wear-resistant liner can be provided on its surface. When the drop-type staggered blades 102 rotate to this position, the material can slide quickly along the discharge ramp 111 towards the discharge port, while the outer end of the wear-resistant end strip 103 will detach from contact with this surface, further improving the smoothness of material discharge.

[0041] Working principle: The feed housing 1 is connected and installed in the dust removal system. The drive device 2 drives the output shaft to rotate the impeller. The sleeve part 101 of the impeller transmits power to make the staggered blades 102 rotate synchronously. The stepped and gradually converging structure of the feed hopper 108 guides the material into the feed chamber in layers. The staggered drop chamber formed by the staggered flat plate section and the arc-shaped connecting section of the staggered blades 102 can break up the material bridging and accumulation to avoid blockage. During rotation, the wear-resistant end strip 103 replaces the staggered blades 102 and the feed chamber. The inner wall contact, its arc-shaped bottom edge 104 reduces contact wear, adapts to the arc-shaped inner wall at the top of the material passage cavity, and can scrape off the material adhering to the inner wall. When the drop-type staggered blade 102 rotates to the unloading slope 111 position at the bottom of the material passage cavity, the outer end of the wear-resistant end strip 103 disengages from the slope to improve the material sliding efficiency. Finally, the material is guided and slid out by the spiral guide plate 110 in the discharge hopper 109. The wear-resistant end strip 103 can be easily installed, removed and maintained by the fastener 107. The various structures work together to achieve efficient anti-clogging unloading and durable wear resistance.

[0042] It should be noted that the specific model and specifications of the drive device 2 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0043] The power supply and principle of the drive device 2 are clear to those skilled in the art and will not be described in detail here.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
