DETAILED DESCRIPTION

[0022] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Reference Figure 1 , an anti-blocking silo valve, comprising a valve body 10 that is connected from top to bottom; a material guide structure 20 is provided on at least one side of the valve body 10, and the material guide structure 20 is a component arranged on the side of the valve body 10, which is communicated with the inside of the valve body 10, and mainly serves to guide the material to flow along a specific path. The material guide structure 20 can optimize the flow direction and speed of the material through its internal channels and settings, reduce the stagnation and accumulation of the material in the valve body 10, and thus reduce the risk of blockage.

[0024] The material guiding structure 20 includes a shield 21 arranged on the side of the valve body 10 and communicating with the inside thereof, a rotating shaft A22 is rotatably arranged in the shield 21, and a plurality of material turning blades 23 are arranged on the rotating shaft A22; the shield 21 is a part of the material guiding structure, which is arranged on the side of the valve body 10 and surrounds the rotating shaft A22. The main function of the shield 21 is to protect the rotating shaft A22 and the material turning blades 23 from external damage, and also to prevent the material from causing wear to the inside of the valve body 10 during the flow process. The rotating shaft A22 is the central axis installed inside the shield 21, and it drives the material turning blades 23 to work by rotating. The design of the rotating shaft A22 allows the material turning blades 23 to rotate around its center, and this rotational motion helps the continuous flow and dispersion of the material and reduces the blockage of the material inside the valve body 10. The material turning blades 23 are blades installed on the rotating shaft A22, and their main function is to turn the material so that it can pass through the valve body 10 smoothly. The design and layout of the material turning blade 23 can ensure that the material flows effectively inside the valve body 10, prevent the material from being retained and accumulated inside the valve body 10, and thus reduce the possibility of blockage.

[0025] The valve body 10 is provided with a valve plate 30 which is located at the top of the material turning leaf 23 and is arranged in an inclined manner. The inclined valve plate 30 can act as a barrier to prevent the material from flowing back to the upper part of the valve body 10 when the valve is closed, thereby ensuring the unidirectional flow of the material. The inclined design can increase the boosting effect for the material, so that the material flows faster along the inclined surface of the valve plate 30, thereby reducing the risk of material blockage. When the material turning leaf 23 throws the material upward, the material will encounter the inclined valve plate 30 after reaching the top. The inclined surface of the valve plate 30 guides the material to move toward the discharge end of the valve body 10, while also increasing the flow rate of the material. When the valve needs to be closed, the valve plate 30 can be adjusted to a position to prevent the material from continuing to flow out. Due to the inclined design of the valve plate 30, even when the valve is closed, it can prevent the material from accumulating in the upper area inside the valve body 10, thereby keeping the inside of the valve clean and smooth. This design improves the material discharge efficiency of the valve and the uniformity of material handling, while also reducing maintenance requirements and operating costs.

[0026] The side of the valve plate 30 close to the inner wall of the valve body 10 is connected to a telescopic component 31 through a hinge, and the end of the telescopic component 31 away from the valve plate 30 is connected to the inner wall of the valve body 10 through a hinge; in addition, the end of the valve plate 30 away from the material turning leaf 23 is connected to the inner wall of the valve body 10 through a hinge. The design of the telescopic component 31 allows the valve plate 30 to change the inclination angle, so that the flow of materials can be controlled as needed. The telescopic component 31 includes but is not limited to an electric or hydraulic push rod, which can drive the valve plate 30 through telescopic movement, thereby realizing the opening and closing of the valve plate 30, and can also improve the material discharge speed by changing the angle of the valve plate 30.

[0027] During the operation of the anti-blocking silo valve, the valve plate 30 opens or closes the flow channel according to the needs of material flow, and the telescopic component 31 controls the movement of the valve plate 30. When the valve plate 30 is opened, the material passes through the valve body 10 smoothly under the action of the turning leaf 23; specifically, the material inside the valve body 10, and then flows along the inclined direction of the valve plate 30 to the turning leaf 23 of the material guide structure 20, and the turning leaf 23 is turned and guided on the rotating shaft A22 in the shield 21 by the gravity of the material, so that the material is quickly thrown out; when the valve plate 30 is closed, the material flow is blocked to prevent material leakage.

[0028] Furthermore, the shield 21 is arc-shaped and surrounds the outer side of the turning track of the material turning blade 23. The shield 21 is designed to be arc-shaped and surrounds the outer side of the turning track of the material turning blade 23. The main purpose of this design is to provide a continuous protective barrier. The arc-shaped shield 21 can better cover and protect the outer area of ​​the rotating shaft A22 and the material turning blade 23 during the rotation process, reducing the direct impact and wear of the material on the side wall of the valve body 10. In addition, this design also helps to guide the material to flow along the preset path, ensuring that the material can be effectively turned and transported under the action of the material turning blade 23.

[0029] Furthermore, the rotating shaft A22 in the shield 21 is close to the inside of the valve body 10, so that the material turning blade 23 on the side of the rotating shaft A22 away from the shield 21 extends into the inside of the valve body 10. The rotating shaft A22 is designed to be close to the inside of the valve body 10, and such a layout enables the material turning blade 23 on the side of the rotating shaft A22 away from the shield 21 to extend into the inside of the valve body 10. This design allows the material turning blade 23 to contact the material more deeply, thereby turning the material more effectively and ensuring the flow and mixing of the material inside the entire valve body 10.

[0030] The internal position of the rotating shaft A22 allows the material turning blade 23 to penetrate into the material pile inside the valve body 10. When the rotating shaft A22 drives the material turning blade 23 to rotate, the material turning blade can not only turn over the material near the shield 21, but also touch and push the material in the center area of ​​the valve body 10, promoting the overall flow of the material.

[0031] Furthermore, the bottom of the inclined surface of the valve plate 30 corresponds to the top position of the material turning blade 23 extending into the valve body 10. This precise alignment design ensures that when the material turning blade 23 turns over driven by the rotating shaft A22, the material can slide smoothly along the inclined surface 32 and be guided to the discharge area of ​​the valve body 10.

[0032] Since the bottom of the inclined surface 32 corresponds to the top position of the material turning leaf 23, when the material turning leaf 23 turns upward, the material is lifted and then slides down along the inclined surface 32. This action helps the flow of the material, so that it naturally moves to the discharge end of the valve body 10 under the action of gravity. The design of the inclined surface 32 not only promotes the smooth flow of the material, but also reduces the stagnation and accumulation of the material inside the valve body 10, thereby reducing the possibility of blockage.

[0033] Furthermore, a counter-attack plate 31 is provided at the bottom of the valve plate 30, and the counter-attack plate 32 is located on the opposite side of the material turning leaf 23 extending into the valve body 10. The counter-attack plate 31 is integrated at the bottom of the valve plate 30, and is located in the middle position where the material turning leaf 23 extends into the valve body 10. The main function of the counter-attack plate 31 is to apply additional force to the material when the material turning leaf 23 turns the material, so as to help the material to move or disperse further and prevent the material from forming a blockage inside the valve body 10. The counter-attack plate 32 is an elastomer, and a plurality of protruding particles are provided on the surface of the counter-attack plate 32. When the elastomer counter-attack plate 32 collides with the material, it can quickly restore its shape through its elastic properties. This rapid deformation and recovery process helps to push the material to continue to flow forward and reduce the stagnation time of the material inside the valve. When the material collides with the counter-attack plate 32, the protruding particles on the surface of the counter-attack plate 32 can break the aggregation state of the material, so that the material is quickly dispersed at the contact point, and the risk of blockage caused by the aggregation of the material is reduced. The raised particles increase the contact surface area between the material and the impact plate 32, which helps the material to diffuse in different directions when in contact, thereby improving the fluidity of the material inside the valve and ensuring that the material can pass through the valve evenly.

[0034] When the turning blade 23 is turned over by the rotating shaft A22, the material is lifted and moves downward inside the valve body 10. At this time, the impact plate 31 located in the middle of the turning blade 23 will generate a reaction force on the falling material, which can help the material move further to the discharge end of the valve body 10 or redistribute inside the valve body 10. This design effectively assists the flow of materials and reduces the stagnation of materials inside the valve body 10. At the same time, the impact plate 31 can also disperse the materials to a certain extent, making the material flow more uniform, improving the overall material discharge efficiency of the valve and the uniformity of material processing.

[0035] The blades of the material turning blade 23 are arc-shaped. The arc-shaped blades can turn the material more effectively because the arc-shaped surface can fit the flow arc of the material, making the material smoother when turning. When the blades rotate, the arc-shaped blades can guide the material to move along the arc-shaped trajectory, which helps the continuous flow of the material and reduces the accumulation of the material. During the operation of the valve, the arc-shaped blades of the material turning blade 23 move with the rotation of the rotating shaft A22. Due to the arc-shaped design of the blades, when the material contacts the blades, the material will move along the curved surface of the arc-shaped blades, be lifted and thrown in a clockwise direction. This throwing action helps the material to form a centrifugal distribution inside the valve body 10, so that the material can be more evenly distributed in the discharge area of ​​the valve body 10.

[0036] Furthermore, a discharge impeller 40 is included, which is disposed in the valve body 10 and near the discharge port of the valve body 10. The design of this impeller is intended to assist the transfer of materials from the inside of the valve body 10 to the discharge port, thereby facilitating the discharge process of the materials. The discharge impeller 40 can push or stir the materials through the rotation of its blades, helping the materials to flow smoothly from the inside of the valve body 10 to the discharge port. The discharge impeller 40 can prevent the materials from accumulating near the discharge port, ensuring that the flow of the materials will not be obstructed due to local accumulation.

[0037] Furthermore, a rotating shaft B41 is rotatably arranged in the unloading impeller 40, one end of the rotating shaft B41 is rotatably arranged on the inner wall of the valve body 10, and the other end extends through the valve body 10; one end of the rotating shaft A22 extends through the valve body 10, and the extending end of the rotating shaft A22 is on the same side as the extending end of the rotating shaft B41, and the two are connected by a belt drive.

[0038] A rotating shaft B41 is installed inside the unloading impeller 40 to ensure that the impeller can rotate effectively. One end of the rotating shaft B41 is fixed to the inner wall of the valve body 10, and the other end passes through and extends out of the valve body 10. This design allows the rotating shaft B41 to be connected to the driving mechanism, thereby driving the unloading impeller 40 to rotate. The rotating shaft A22 is the driving shaft of the material turning blade 23, and one end of it also passes through and extends out of the valve body 10. The extended end of the rotating shaft A22 and the extended end of the rotating shaft B41 are located on the same side of the valve body 10, which means that they can be connected by belt drive on the same side outside the valve body 10. This connection method allows a speed matching and transmission between the material turning blade 23 and the unloading impeller 40.

[0039] When the rotating shaft A22 starts to rotate, its power is transmitted to the rotating shaft B41 through the belt drive, thereby driving the unloading impeller 40 to rotate. This ensures that the operation between the material turning blade 23 and the unloading impeller 40 is synchronized, thereby improving the efficiency of the entire valve system. After the material turning blade 23 turns up the material, the rotation of the unloading impeller 40 can assist the material to move further, ensuring that the flow of the material inside the valve body 10 is continuous and reducing the stagnation of the material inside the valve body. The connection between the rotating shaft A22 and the rotating shaft B41 ensures that the material turned up by the material turning blade 23 can be promptly received by the unloading impeller 40 and pushed to the discharge port, thereby optimizing the entire unloading process.

[0040] In addition, the belt 42 is a toothed belt, and the extended ends of the rotating shaft A 22 and the rotating shaft B 41 are both provided with toothed pulleys adapted to the toothed belt. The toothed pulley can ensure that the belt will not slip during the transmission process, provide accurate power transmission, and ensure the synchronous operation between the rotating shaft A 22 and the rotating shaft B 41. The engagement of the toothed belt and the pulley increases the friction force, ensuring stable transmission even under high load or high-speed operation. This design using a toothed belt and a toothed pulley improves the transmission efficiency and reliability of the entire valve system, and also makes the entire system more stable and durable. In this way, the turning blade 23 and the unloading impeller 40 can work together more effectively to ensure that the material is smoothly transported from the inside of the valve body (10) to the discharge port.

[0041] Furthermore, it also includes an intermittent mechanism 50, which includes a motor 51 fixed on one side of the valve body 10, a connecting rod 52 passing through the output shaft of the motor 51, and an intermittent plate A53 and an intermittent plate B54 hinged at the upper and lower ends of the connecting rod 52; wherein the intermittent plate A53 and the intermittent plate B54 slide from the side of the valve body 10 to the loading port and the unloading port of the valve body 10 respectively.

[0042] The intermittent mechanism 50 is a key part for realizing automatic control of the valve. It drives the motor 51 to make the connecting rod 52 reciprocate, thereby driving the intermittent plate A53 and the intermittent plate B54 to perform intermittent operation. As the power source of the intermittent mechanism 50, the motor 51 is fixed on one side of the valve body 10 and is responsible for driving the reciprocating motion of the connecting rod 52. The start and stop of the motor 51 controls the operation of the entire intermittent mechanism and is the core component for realizing automatic control of the valve. The connecting rod 52 is a mechanical connection component between the motor 51 and the intermittent plate A53 and the intermittent plate B54. It runs through the output shaft of the motor 51 and converts the rotational motion of the motor into reciprocating linear motion, thereby realizing the opening and closing of the intermittent plate. The intermittent plate A53 and the intermittent plate B54 are respectively located at the upper and lower feeding ports of the valve body 10, and are connected to the upper and lower ends of the connecting rod 52 by hinges. Driven by the motor 51, they realize the automatic opening and closing of the upper and lower feeding ports of the valve to control the flow of materials.

[0043] During the feeding process of the valve, when the motor 51 rotates forward, it drives the intermittent plate A53 to move through the connecting rod 52, so that the intermittent plate A53 slides along the side of the valve body 10 to the feed port, opens the feed port, and realizes quantitative feeding. At the same time, the intermittent plate B54, driven by the connecting rod 52, slides along the side of the valve body 10 to the discharge port and closes the discharge port. When the quantitative feeding is completed, the motor 51 rotates in the opposite direction, the intermittent plate A53 closes the feed port, and the intermittent plate B54 opens the discharge port, thus ensuring that the feeding amount is equal to the discharge amount each time. This synchronous opening and closing action ensures the precise control of the material and prevents leakage or overflow of the material during the feeding or discharging process.

[0044] A common design that uses a floating member, such as a spring, at the end of the connecting rod where the hinge is connected is used to absorb shock and vibration during movement while providing the necessary degrees of freedom to accommodate the different movement requirements when the connecting rod swings. The floating member allows the intermittent plate to move flexibly to a certain extent, rather than in a completely rigid arc, which helps to reduce the asynchronous movement of the intermittent plate caused by the swing of the connecting rod. The elastic effect of the floating member can improve the smoothness of the movement of the intermittent plate and avoid the intermittent plate movement being too rigid or uneven due to the reciprocating motion of the connecting rod.

[0045] Please refer to Figure 2 , and also includes a pushing mechanism 60 arranged on the valve plate 30, the pushing mechanism 60 includes a push rod 61 fixed on the valve plate 30, and a pushing cover 62 fixed to the piston end of the push rod 61; wherein the valve plate 30 is provided with an outer cover 63 surrounding the push rod 61, and the outer wall of the pushing cover 62 is slidably connected to the inner wall of the outer cover 63.

[0046] The push mechanism 60 is a device arranged on the valve plate 30, which includes a push rod 61 and a push cover 62. The main purpose of the push mechanism 60 arranged on the valve plate 30 is to provide an additional propulsion force at each intermittent feeding. This propulsion force can help the material overcome the gravity and friction at the feed port, ensure that the material enters the valve body 10 smoothly, and reduce or avoid blockage at the feed port. The push rod 61 is fixed on the valve plate 30 and is an important part of the push mechanism 60. It is responsible for transmitting force to the push cover 62 to push the material to move. The push rod 61 is usually made of a strong material to ensure sufficient strength and durability when pushing the material. The push cover 62 is fixed to the piston end of the push rod 61 and is in direct contact with the material. Its design usually takes into account compatibility with the material and gentle handling of the material to avoid damage to the material. The outer wall of the push cover 62 is slidably connected to the inner wall of the outer cover 63. This design allows the push cover 62 to move smoothly when pushing the material. The outer cover 63 surrounds the push rod 61, plays a role in protecting the push rod 61 and the material pushing cover 62, and also helps to maintain the cleanliness of the material pushing mechanism 60 and prevent external impurities from entering the interior of the mechanism.

[0047] During the operation of the valve, when the push mechanism 60 starts to work, the push rod 61 moves under the action of the driving force and pushes the push cover 62 fixed to its piston end. The push cover 62 contacts the material and pushes the material to the discharge port. The outer cover 63 ensures the smooth movement of the push cover 62 and prevents the push rod 61 from being disturbed by the outside world during the movement. The push mechanism 60 of this design provides the necessary propulsion force for the material through the coordinated work of the push rod 61 and the push cover 62, so that the material can overcome the resistance and enter the valve body 10 smoothly. In the process of the material entering the valve body 10, the push mechanism 60 helps to break up the material accumulation or bridge arch that may be formed at the feed port, thereby reducing the risk of blockage.

[0048] Please refer to Figure 3 , and also includes a pressure relief mechanism 70 arranged in the valve plate 30, the pressure relief mechanism 70 includes a piston cylinder 71 with an air inlet hole arranged at the feed port of the valve body 10, and the end of the intermittent plate A53 away from the connecting rod 52 is connected to a U-shaped piston column 72 that passes through the valve body 10, and the end of the piston column 72 away from the intermittent plate A53 passes through the valve body 10 and is slidably connected in the piston cylinder 71, and the side of the piston column 72 away from the piston cylinder 71 is connected to the pressure relief pipe 74 at the bottom thereof through a connection 73, and a plurality of pressure relief holes 75 are provided on the front and rear sides of the pressure relief pipe 74; wherein an inverted V-shaped material dividing plate 76 is provided on the top of the piston cylinder 71.

[0049] The pressure relief mechanism 70 is a device arranged in the valve plate 30, which is mainly used to provide an auxiliary blowing effect when the intermittent plate A53 is opened, to help the material enter the valve body 10 smoothly and prevent blockage. The piston cylinder 71 is a part of the pressure relief mechanism 70, which is arranged at the feed port of the valve body 10 and has an air inlet. Its function is to serve as a sliding channel for the U-shaped piston column 72, and to allow gas to enter to generate a pressure difference to assist the flow of materials. The U-shaped piston column 72 is connected to one end of the intermittent plate A53 and passes through the valve body 10. Its main function is to assist the flow of materials by sliding in the piston cylinder 71 when the intermittent plate A53 is opened. The pressure relief pipe 74 is connected to one side of the U-shaped piston column 72 for adjusting the pressure in the valve body. The pressure relief hole 75 on the pressure relief pipe 74 helps to release the pressure in the valve body, and the air flow pressure is released to reduce the material blowing to increase the material feeding speed. The pressure relief holes 75 are arranged on both sides of the pressure relief pipe 74 to control the pressure in the valve body, ensure the smooth flow of materials, and reduce the accumulation of materials at the feed port. The inverted V-shaped material distribution plate 76 on the top of the piston cylinder 71 helps to disperse the materials so that they enter the valve body 10 evenly, reduce the direct impact of the materials at the feed port, and avoid blockage.

[0050] When the intermittent plate A53 is opened, the pressure relief mechanism 70 starts to work. The piston cylinder 71 allows gas to enter through the air inlet hole thereon, and the U-shaped piston column 72 slides in the piston cylinder 71, generating a pressure difference. This pressure difference is adjusted through the pressure relief pipe 74 and the pressure relief hole 75, which helps the flow of materials. At the same time, the inverted V-shaped material distribution plate 76 disperses the materials so that they enter the valve body 10 evenly, reducing the accumulation of materials at the feed port.

[0051] When the intermittent plate A53 is opened, the air pressure in the piston cylinder 71 decreases, storing the negative pressure of the external air. When the intermittent plate A53 is closed, the air pressure in the piston cylinder 71 is restored, releasing the stored air pressure. When the air pressure in the piston cylinder 71 decreases, the material is subjected to the dual effects of gravity and negative pressure, and can flow into the valve body 10 faster. At the same time, after the intermittent plate A53 is closed, the presence of positive pressure will push the material to flow downward, ensuring that the material passes smoothly through the discharge port. For example, in a feeding cycle, the negative pressure state causes the material to fall rapidly in the valve body, and after closing, the positive pressure pushes the material out, ensuring that the feed amount is equal to the discharge amount each time. In this way, the pressure relief mechanism 70 effectively adjusts the air pressure state in the valve body 10, ensures the smoothness of material flow, reduces the risk of blockage, and improves the efficiency of the entire system.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
