[0003] The prior art discloses a rotary discharge valve with a leakage prevention wear structure with the application number CN202122119485.4, and the prior art discloses a rotary discharge valve with a leakage prevention wear structure with the application number CN202122119485.4, which is provided with a plurality of leakage prevention plates and a rotating column for driving the leakage prevention plates to swing on the valve body, and according to the content of the specification and the attached drawings, the leakage prevention plates need to be swung and fixed in a perpendicular state with the inlet end of the valve body when the rotary discharge valve is aligned with the material conveying end of the external material conveying device to prevent material overflow, but the leakage prevention plates need to be swung and fixed in sequence every time the preventive measures are taken, and the whole operation process is complicated and inefficient, and at the same time, the leakage prevention plates still have gaps with the material conveying end of the external material conveying device, which can still cause material overflow. UTILITY MODEL CONTENT

[0004] In view of the deficiencies of the prior art, the utility model provides a rotary discharge valve with a leakage prevention wear structure to solve the problems of low strength of the leakage prevention structure of the traditional rotary discharge valve and complicated operation.

[0005] The utility model provides a kind of rotary discharge valve with anti-leakage wear structure to achieve the above-mentioned purpose, including valve body, the valve body top is equipped with inlet, the valve body top outer wall is circumferentially provided with base plate, the base plate is provided with the anti-leakage cover for stretching and covering the material transfer port when the material transfer port of external material conveying structure is aligned with inlet, the anti-leakage cover is penetrated with the material transfer port output of external material conveying structure is transferred to the material transfer hole of inlet, the anti-leakage cover top is provided with the connecting piece for the top inner wall of material transfer hole and the outer wall of external material transfer port stable connection.

[0006] The above technical scheme has the advantages that: first, the valve body is placed in the predetermined installation position to ensure its stability, and the material transfer port of the external material conveying structure is aligned with the inlet at the top of the valve body. Then, the anti-leakage cover is pulled up to cover the space between the material transfer port and the inlet. The connecting piece at the top of the anti-leakage cover is used to tightly connect the top inner wall of the material transfer hole with the outer wall of the external material transfer port, ensuring stable connection without looseness. The external material conveying structure is started, and the material is output from the material transfer port and smoothly transferred to the inlet of the valve body through the material transfer hole of the anti-leakage cover, and then enters the rotary discharge valve for subsequent unloading operation. Through the design of the anti-leakage cover, when the material transfer port of the external material conveying structure is aligned with the inlet, it can be stretched and covered. This design effectively fills the gap that may exist between the material transfer port and the inlet, greatly reduces the risk of material leakage during transportation, avoids material waste, reduces pollution to the production environment, and also reduces the cleaning cost and production interruption risk caused by material leakage. The connecting piece at the top of the anti-leakage cover can stably connect the top inner wall of the material transfer hole with the outer wall of the external material transfer port. This not only further enhances the anti-leakage effect, but also ensures the smoothness of the material during transportation, preventing problems such as material blockage or poor transportation caused by unstable connection, improving production efficiency, and reducing direct erosion and friction of material on the valve body and related components through reasonable structural design. Especially, the existence of the anti-leakage cover blocks the impact of material on the key parts to some extent, prolongs the service life of the rotary discharge valve, and reduces the maintenance and replacement cost of the equipment.

[0007] The utility model further provides: the anti-leakage cover is bellows, the bellows is made by connecting a plurality of foldable corrugated pieces along the folding and telescoping direction.

[0008] The technical scheme has the beneficial effects that: the leak-proof sleeve adopts a bellows structure, which is made of a plurality of foldable corrugated pieces connected along the folding and stretching direction, which gives the leak-proof sleeve very high flexibility. In actual application, when the material conveying port of the external material conveying structure is docked with the material inlet of the valve body, even if there is a certain angle deviation or position error between the two, the bellows can easily adapt to the adjustment by virtue of the characteristics of the foldable corrugated pieces. It can be flexibly stretched and bent, closely fit the shape and position of the material conveying port, ensure seamless docking, effectively avoid the problem of material leakage caused by inaccurate docking, and greatly improve the applicability of the rotary discharge valve under different working conditions; and the bellows structure formed by the foldable corrugated pieces connected with each other can be pressed between the corrugated pieces when subjected to the material conveying pressure, forming multiple sealing lines. This unique sealing mechanism can effectively prevent material from overflowing from the connection between the leak-proof sleeve and the material conveying port. Compared with the traditional planar sealing structure, the sealing performance of the bellows is more reliable, and even in the process of long-time and high-pressure material conveying, it can always maintain good sealing state, providing a strong guarantee for the safe conveying of materials; at the same time, in the process of material conveying, the flow of material will generate a certain impact force and vibration, and the foldable corrugated piece structure of the bellows can play an excellent buffering and damping effect. When the material impacts the leak-proof sleeve, the corrugated piece can absorb part of the impact force through its deformation, reducing the transmission of vibration to the valve body and other components. This not only helps to protect the internal structure of the rotary discharge valve and prolong its service life, but also reduces the noise during equipment operation, creating a more quiet working environment.

[0009] The utility model further sets up: the leak-proof sleeve top is evenly distributed with a plurality of adsorption strips around, the adsorption strip is made of soft magnet strip and adsorption strip is connecting piece, a plurality of adsorption strips all set up on the inner wall on the top of the material passing hole.

[0010] The technical scheme has the beneficial effects that: the adsorption strips evenly distributed in the ring direction on the top of the leakage-proof sleeve are made of soft magnetic strips, which greatly simplifies the connection process of the external material conveying port and the material passing hole. In actual operation, when the material conveying port is close to the material passing hole, the soft magnetic strips will automatically adsorb on the outer peripheral wall of the material conveying port by virtue of their own magnetism, without the need for additional complex connection tools or cumbersome installation steps, so that stable connection can be quickly realized, the installation and debugging efficiency of the equipment is greatly improved, the time cost caused by connection operation is reduced, and since the adsorption strips are evenly distributed in the ring direction on the inner peripheral wall of the top of the material passing hole, when they are adsorbed on the outer peripheral wall of the material conveying port, a uniform and tight sealing ring can be formed. This not only effectively prevents material leakage from the connection gap, but also ensures the stability and reliability of the sealing effect during material conveying, even if subjected to certain pressure fluctuations or external force interference, the adsorption strips can still rely on their magnetism to maintain tight fitting, thereby providing a solid guarantee for the safe conveying of materials. The material properties of the soft magnetic strips endow the adsorption strips with good flexibility. This enables the adsorption strips to adaptively adjust to the profile of the material conveying port when connected with material conveying ports of different shapes and materials, and tightly fit the surface of the material conveying port. Whether the material conveying port is circular, square or of other irregular shapes, the adsorption strips can perfectly adapt to the material conveying port, effectively avoiding the problem of poor sealing caused by differences in port shapes, expanding the application range of the rotary discharge valve, and the soft magnetic strips have better anti-vibration and anti-impact capability compared with ordinary rigid connecting parts. During material conveying, the equipment is inevitably subject to vibration, and the soft material of the adsorption strips can effectively buffer these vibrations and reduce connection loosening and wear caused by vibration. At the same time, the magnetic adsorption connection method avoids the damage of components caused by frequent disassembly and installation in traditional mechanical connection, thereby prolonging the service life of the adsorption strips and the entire leakage-proof sleeve and reducing the maintenance cost of the equipment.

[0011] The utility model further sets up: adjacent adsorption strip gap cooperation and form deformation gap, leakage-proof sleeve top outer peripheral wall correspond to each deformation gap all set up deformation groove, a plurality of deformation groove all with material passing hole communication arrangement, deformation groove radial section is set up in " V " shape.

[0012] The technical scheme has the beneficial effects that: the existence of the deformation gap enables the adjacent adsorption strips to be close to each other when the adsorption strips are adsorbed to the external device, and then the adsorption strips are combined to form a ring. The ring structure ensures uniform surrounding and stable adsorption of the material conveying port, provides reliable sealing protection for material conveying, avoids material leakage from the gap between the adsorption strips, improves the sealing effect of the entire leakage prevention system, and reduces material waste and environmental pollution. Since the adsorption strips can be close to each other to form a ring through the deformation gap, the leakage prevention sleeve can adapt to material conveying ports of different sizes. Regardless of the size of the diameter of the material conveying port, the adsorption strips can be flexibly adjusted according to the size of the port to ensure close fitting, thereby expanding the application range of the rotary discharge valve, improving the versatility of the equipment, and reducing the cost and complexity of special design for different specifications of equipment. The ring adsorption structure formed through the deformation gap simplifies the connection operation of the leakage prevention sleeve and the external device. During installation, the adsorption strips can naturally form a ring by being close to each other and are adsorbed to the material conveying port, without the need for accurate adjustment of the position and spacing of the adsorption strips, thereby greatly improving the installation efficiency and reducing the installation time and labor cost.

[0013] The utility model further sets up: the inner peripheral wall of the material passing hole bottom is circumferentially provided with a leakage prevention ring, the leakage prevention ring shaft hole diameter is matched with the feeding port diameter, and the leakage prevention ring bottom wall is abutted and matched with the valve body top end face.

[0014] The technical scheme has the beneficial effects that: the leakage prevention ring circumferentially arranged on the inner peripheral wall of the material passing hole bottom can further prevent material leakage during the transmission of the material from the material passing hole to the feeding port. The leakage prevention ring is matched with the diameter of the feeding port, and the bottom wall thereof is abutted and matched with the top end face of the valve body, thereby forming an additional sealing barrier, effectively blocking the leakage of the material from the gap between the bottom of the material passing hole and the feeding port, enhancing the overall sealing effect, ensuring the sealing property of the material during the conveying process, and reducing material loss and environmental pollution. The arrangement of the leakage prevention ring protects the top of the valve body to a certain extent, and it can block the direct impact and wear of the material on the top of the valve body, especially during long-term use, thereby reducing the erosion of the material on the valve body, prolonging the service life of the valve body, and reducing the maintenance cost and repair frequency of the equipment.

[0015] The utility model further sets up: the base plate and valve body are detachably connected with a plurality of connecting bolts.

[0016] The substrate and the valve body are detachably connected through the connecting bolts, so that in the installation process of the rotary discharge valve, the parts of the substrate and the valve body can be assembled respectively, and then connected through the connecting bolts, so that the operation is simple and convenient. When the equipment needs to be maintained, repaired or parts are replaced, the substrate and the valve body can be easily separated only by disassembling the connecting bolts, so that the installation and maintenance efficiency is greatly improved, and the time and labor cost required for equipment maintenance are reduced.
