DETAILED DESCRIPTION

[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 1-2 The utility model provides a technical solution: a fast non-accumulation material storage device valve, comprising a discharge valve body 1, a discharge channel 3 is arranged inside the discharge valve body 1, a discharge valve plate 7 is slidably connected to the inner side of the discharge channel 3, a connecting seat 2 is fixedly installed on the left side of the discharge valve body 1, a valve stem 10 for connecting and driving is fixedly installed on the right side of the discharge valve plate 7, and a cylinder 14 for driving is fixedly installed on the other end of the valve stem 10; by designing a fast non-accumulation discharge valve body 1 and changing the structure of the feed port 4, the discharge speed can be accelerated and the accumulation of materials in the valve can be prevented; by adding a guide groove 6 for the movement of the discharge valve plate 7, the position of the discharge valve plate 7 is not easily offset under the impact force of the material; and by optimizing the structure of the connecting seat 2, the sealing performance can be further enhanced.

[0023] In this embodiment, the discharge channel 3 is a structure for allowing solid particles to pass through quickly.

[0024] like Figure 1 and Figure 2 As shown, the two sides of the discharge channel 3 are respectively provided with a feed port 4 and a discharge port 5, and the inner side of the discharge channel 3 is provided with a guide groove 6 for sliding a discharge valve plate 7.

[0025] It should be noted that a sealing gasket 8 and a rubber ring 9 are bonded to the outer side of the discharge valve plate 7 for sealing. The outer sides of the sealing gasket 8 and the rubber ring 9 are both in contact with the inner side of the feed port 4. Through the coordinated use of the sealing gasket 8 and the rubber ring 9, a good sealing effect can be achieved on the outer side of the discharge valve plate 7, so that the material can move along the specified path.

[0026] In addition, the rubber ring 9 is a wear-resistant and corrosion-resistant rubber sealing structure, and the sealing gasket 8 is a rubber gasket with sealing ability, which can improve the service life so that the sealing gasket 8 and the rubber ring 9 can maintain a normal working state for a long time. Specifically, the discharge valve plate 7 relies on the sealing gasket 8 and the rubber ring 9 to seal with the inside of the connecting seat 2. The rubber ring 9 is made of wear-resistant and corrosion-resistant material. On the one hand, it enhances the sealing performance when the discharge valve is closed, and on the other hand, it prevents particulate materials from being stuck in the sealing position connection when the valve is closed.

[0027] In addition, a limiting sleeve 11 located on the outside of the valve stem 10 is fixedly installed inside the discharge valve body 1, and the inside of the limiting sleeve 11 is filled with a packing 12 for sealing. A pressure cap 13 is fixedly installed on the right side of the limiting sleeve 11. The packing 12 is used to fill and seal the outside of the valve stem 10, and the pressure of the pressure cap 13 is combined to further enhance the sealing ability and prevent material leakage. When the valve stem 10 moves, it slides inside the packing 12, so that the packing 12 can play a certain sealing role.

[0028] It should also be noted that a connecting device 15 is fixedly installed between the end of the valve stem 10 and the output shaft of the cylinder 14, and a cylinder fixing seat 16 for reducing the impact force of discharging is fixedly installed between the left side of the cylinder 14 and the right side of the discharge valve body 1. The cylinder fixing seat 16 can provide a fixed installation between the cylinder 14 and the discharge valve body 1, wherein the pressure cover 13 is located inside the cylinder fixing seat 16 and is fixedly connected to the right side of the discharge valve body 1, and a limit switch 17 is fixedly installed on the outside of the cylinder 14 to prevent the cylinder 14 from exceeding the stroke limit, wherein the limit switch 17 is a switch structure for limiting the stroke, and by setting the limit switch 17, the stroke of the cylinder 14 can be prevented from exceeding the specified distance, thereby playing a preventive and protective role for the operation of the cylinder 14.

[0029] At the same time, the feed port 4 is a square structure, the discharge port 5 is inclined to the side close to the bottom, and the inner side of the discharge port 5 is circular. The structural setting of the transition from square to circular can accelerate the flow speed of the material inside the discharge channel 3, and at the same time prevent the accumulation of material particles in the valve and cause blockage.

[0030] In addition, the connecting device 15 includes a square plate, which is fixedly connected to the end of the valve stem 10 and the output shaft of the cylinder 14 by bolts. The valve stem 10 can be fixed to the output shaft of the cylinder 14 through the cooperation of the square plate and the bolts, so that the cylinder 14 can drive the valve stem 10 to move through the connecting device 15. The outer structure of the connecting seat 2 is arc-shaped, and the left side of the connecting seat 2 is in contact with the storage tank body. The inner wall of the connecting seat 2 adopts a trapezoidal structure, which can be sealed with the discharge valve plate 7. Specifically, a plurality of cylinder fixing seats 16 can be installed at the bottom of the cylinder 14, which can further improve the stability of the overall structure.

[0031] The working principle of the above embodiment is:

[0032] When the material is discharged, the cylinder 14 drives the valve stem 10 through the connecting device 15 to drive the discharge valve plate 7 to move horizontally along and fit the guide groove 6 inside the discharge channel 3, thereby preventing the discharge valve plate 7 from shifting under the impact force of the material, and the material will not accumulate due to the guide groove 6, so that the material can be discharged normally through the discharge port 5.

[0033] Compared with the prior art, the valve of the rapid non-accumulation material storage device can speed up the discharge speed and prevent the accumulation of materials in the valve by designing a rapid non-accumulation discharge valve body 1 and changing the structure of the feed port 4. By adding a guide groove 6 for the movement of the discharge valve plate 7, the position of the discharge valve plate 7 is not easily shifted under the impact force of the material. By optimizing the structure of the connecting seat 2, the sealing performance can be further enhanced, thereby solving the problem that the existing discharge valve is easily blocked due to the continuous discharge of solid particles during actual use.

[0034] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a small control computer for control, and the existing public power connection technology is not described in detail in the article.

[0035] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0036] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
