Description

Technical Field

[0001] The utility model relates to the technical field of storage equipment for bulk solid materials, in particular to a one-way valve device for a mobile storage tank. Background Art

[0002] During the unloading or transfer process of mobile solid particulate matter (such as powder, granular chemical raw materials, food raw materials, mineral powder, etc.) storage tanks, there is often a problem that the solid particulate matter cannot be completely discharged and is retained in the storage tank or valve, which not only affects work efficiency but also may cause environmental pollution and material loss.

[0003] The one-way valves in existing storage tanks mostly use simple baffles or spring structures. Although they can initially achieve one-way conduction, they are prone to valve clogging due to particle accumulation when handling particles with a certain humidity or easy to agglomerate. In addition, this type of one-way valve has a poor sealing effect on dust, resulting in a large amount of dust during transportation and unloading, which not only pollutes the environment but also wastes materials.

[0004] Traditional tank mouth sealing mostly relies on rubber rings or threaded caps. Severe vibrations during transportation may cause the rubber rings and threaded caps to loosen and cause leakage. Traditional valves often require complex operations such as rotation and pulling, which are laborious to operate. Utility Model Content

[0005] In view of the problems existing in the prior art, the utility model proposes a one-way valve device for a mobile storage tank to achieve efficient, safe and environmentally friendly one-way flow control of solid particles, prevent solid particles from being trapped in the storage tank or valve, and keep the valve unobstructed.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A one-way valve device for a mobile storage tank comprises a storage tank, a tank body welding notch and a one-way valve detachably mounted on the tank body welding notch. The tank body welding notch is fixedly welded to the tank mouth of the storage tank. The one-way valve comprises a valve body shell, a valve cone, a valve body inner shell, a compression spring, a valve cone rod support rod, and a valve cone rod. The valve body shell is rotatably connected to the tank body welding notch via a thread, so that the one-way valve is easily replaced.

[0008] The inner shell of the valve body is threadedly connected to the outer shell of the valve body, the valve cone is always located on the side of the inner shell of the valve body close to the tank body of the storage tank, and the shape of the valve cone matches the inner shell of the valve body to completely seal the tank mouth of the storage tank; the valve cone is connected to the valve cone rod support rod through the valve cone rod.

[0009] The two ends of the compression spring are connected to the valve cone rod support rod and the valve body shell respectively, and the compression spring is placed vertically; the valve cone rod support rod is connected to the limiting structure to slide in the valve body shell. The elastic force of the compression spring continuously presses the cone valve, and can cooperate with the inner shell of the valve body to press the valve port.

[0010] Furthermore, the limiting structure includes an indexing pin and a valve cone supporting flange, the valve cone supporting flange is fixedly connected to the outer ring of the valve cone stem supporting rod, a socket is opened on the valve body shell, and the indexing pin passes through the socket and is slidably inserted into the valve cone supporting flange.

[0011] Furthermore, a feed port is provided on the storage tank body.

[0012] Furthermore, the valve cone adopts a special geometric shape and has a smooth surface, so as to ensure that during the flow of particles, particles that may be attached to the valve cone are automatically removed by the gravity and fluidity of the material itself, thereby preventing valve failure due to blockage.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model proposes a self-cleaning anti-blocking one-way valve that can adapt to the characteristics of transporting solid particles with high humidity and easy to agglomerate, effectively preventing valve blockage caused by particle accumulation and ensuring smooth flow of materials in the storage tank.

[0015] 2. Strengthen the sealing performance of the one-way valve, adopt high-efficiency sealing technology and guide mechanism, greatly reduce or even eliminate dust leakage, thereby improving the working environment, reducing environmental pollution, and reducing material loss.

[0016] 3. By optimizing the overall structure and functional design, the working efficiency of the mobile solid particle storage tank is improved, the equipment's adaptability to various working conditions is enhanced, the service life of the one-way valve and the entire system is extended, and a safer, more environmentally friendly and efficient solid particle storage and transfer operation is achieved.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 The utility model proposes a one-way valve device for a mobile storage tank, which includes a storage tank 10, a feed port 20 and a one-way valve 30. The feed port 20 is arranged at the upper end of the storage tank 10, and the one-way valve 30 is installed at the tank port at the lower end of the storage tank 10. The material enters the storage tank 10 from the feed port 20, and the one-way valve 30 is used to control the discharge of the material in the storage tank 10.

[0023] A tank body welding notch 1 is welded at the tank mouth of the storage tank 10, and the one-way valve 30 can be installed on the tank body welding notch 1 by threaded rotation. The one-way valve 30 includes a valve body shell 2, a valve cone 4, a valve cone rod 8, a valve cone rod support rod 7, a compression spring 6, and a valve body inner shell 5. The valve body shell 2 is installed on the tank body welding notch 1 by threaded rotation, so that the one-way valve 30 can be replaced, and the valve body inner shell 5 is inserted into the valve body shell 2 by threaded rotation. The valve cone rod support rod 7 is horizontally placed, the valve cone rod 8 is connected to the valve cone rod support rod 7 in a T-shaped structure, and the valve cone 4 is connected to the other end of the valve cone rod 8. The valve body inner shell 5 is located between the valve cone 4 and the valve cone rod support rod 7, and the valve cone 4 is always located on the side of the valve body shell 5 close to the tank body of the storage tank 10.

[0024] Both sides of the valve cone rod support rod 7 are connected to compression springs 6, which are in a vertically compressed state, and one end of the compression spring 6 away from the valve cone rod support rod 7 is fixed to the valve body shell 2. The shape of the valve cone 4 is adapted to the valve body inner shell 5. In the natural state, the compression spring 6 pushes the valve cone rod support rod 7 toward the tank port, driving the valve cone 4 to press the valve body inner shell 5 to block the valve port.

[0025] The outer ring of the support rod 7 is connected to a valve cone support flange 9, which always slides in the valve body shell 2. A dividing pin 3 is inserted outside the valve cone support flange 9. By pulling open and inserting the dividing pin 3, the valve cone support flange 9 can be clamped to achieve self-locking.

[0026] The entire valve body of the one-way valve 30 is made of high-strength wear-resistant material, and the internal design has a reasonable flow channel structure to adapt to the flow characteristics of solid particles. The valve cone 4 and the valve body inner shell 5 cooperate to achieve sealing, ensuring that when the valve is closed, the backflow of solid particles and the leakage of dust are effectively prevented.

[0027] Working principle: Solid particles enter the storage tank 10 through the feed port 20 and are stored in the tank body. After the storage tank 10 is transported to the discharge station, the indexing pin 3 is pulled open to loosen the valve cone support flange 9, and the valve cone stem support rod 7 is pushed inward manually or by installing a cylinder structure to compress the compression spring 6, driving the valve cone 4 to rise, and a leak appears between the valve cone 4 and the valve body inner shell 5, so that the one-way valve 30 is opened and the solid particles can flow downward. After the solid particles are dumped, the valve cone stem support rod 7 is loosened, and the valve cone 4 is pressed against the valve body inner shell 5 by the elastic force of the compression spring 6, so that the one-way valve 30 is closed, and then the indexing pin 3 is inserted to clamp the valve cone support flange 9 to achieve self-locking.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
