AI Technical Summary
In the current cement production process, hydraulically driven valves close slowly and take a long time.
Design a ash hopper unloading valve structure, which uses an upper cylinder and a lower cylinder in cooperation, and integrates a buffer chamber. The buffer chamber is used to store materials to achieve rapid closing. The push rod and auxiliary plate share the weight of the push plate to improve safety and ease of operation.
This enables rapid valve closure, reduces closure time, and improves operational convenience and safety.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cement production and processing technology, and specifically relates to a structure for a ash hopper unloading valve. Background Technology
[0002] Various material storage bins are needed in the cement production process. Currently, the valves in these bins are all single valves, and most of them are hydraulically driven. This type of valve closes slowly and takes a lot of time. Utility Model Content
[0003] The purpose of this utility model is to provide a ash hopper unloading valve structure to address the problems mentioned in the background art, based on the current situation.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a hopper discharge valve structure, including a hopper and a discharge pipe, characterized in that: a discharge pipe is provided at the bottom of the hopper, a buffer chamber is provided in the middle of the discharge pipe, an upper cylinder is provided at the upper part of the discharge pipe, a lower cylinder is provided at the lower part of the discharge pipe, the upper cylinder and the lower cylinder have the same structure, an air inlet and an air outlet are provided on the upper cylinder, a push rod is provided at the center position on the left side of the upper cylinder, a push plate is provided on the left side of the push rod, a matching groove is opened on the discharge pipe to cooperate with the push plate, and a discharge port is provided at the bottom of the discharge pipe.
[0005] Preferably, auxiliary rods are provided at the four corners of the middle edge of the upper cylinder, and an auxiliary plate is provided on the left side of the push rod. The auxiliary plate is sleeved on the outside of the auxiliary rod and can slide left and right along the auxiliary rod.
[0006] Beneficial effects: This utility model integrates a buffer chamber on the feeding pipe. The internal capacity of the buffer chamber is larger than that of the feeding pipe. After the lower cylinder is closed, the material is stored in the buffer chamber. At this time, when the upper cylinder is closed, the resistance is relatively low and the closing time is short. Attached Figure Description
[0007] The accompanying drawings are provided to further illustrate the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention, but do not constitute a limitation thereof. In the drawings:
[0008] Figure 1 This is a schematic diagram of the structure of this utility model;
[0009] Figure 2 This is a schematic diagram of the auxiliary plate position structure of this utility model. Detailed Implementation
[0010] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0011] like Figure 1 , Figure 2 As shown, a hopper discharge valve structure includes a hopper 10 and a discharge pipe 3. The structure is characterized by: a discharge pipe 3 at the bottom of the hopper 10; a buffer chamber 2 in the middle of the discharge pipe 3; an upper cylinder 8 at the top of the discharge pipe 3; and a lower cylinder 7 at the bottom of the discharge pipe 3. The upper cylinder 8 and lower cylinder 7 have the same structure. The upper cylinder 8 has an air inlet and an air outlet. A push rod 6 is located at the center left side of the upper cylinder 8, and a push plate 1 is located to the left of the push rod 6. A matching groove is formed on the discharge pipe 3 to cooperate with the push plate 1. A discharge port 4 is located at the bottom of the discharge pipe 3. Auxiliary rods 9 are respectively located at the four corners of the middle edge of the upper cylinder 8. An auxiliary plate 5 is located to the left of the push rod 6 and is sleeved on the auxiliary rod 9. The material can slide left and right along the auxiliary rod 9. The entire structure uses an upper cylinder 8 and a lower cylinder 7 in cooperation. A buffer chamber 2 is set in the middle of the feeding pipe 3. The internal storage space of the buffer chamber 2 is larger than that of the feeding pipe 3. After the lower cylinder 7 is closed, the material will accumulate in the buffer chamber 2. At this time, the upper cylinder 8 is closed, and the entire feeding pipe 3 is completely closed. This method is convenient to open and close. The material at the bottom of the hopper 10 is supported by two push plates 1, which has a high safety. The push plates 1 will not be deformed due to the weight of the material. The weight of the push rod 1 is transferred to the auxiliary rod 9 through the auxiliary plate 5, which further reduces the pressure on the push plate 1. This makes opening and closing convenient.
[0012] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0013] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
