Description

Technical Field

[0001] This utility model relates to the field of spray tower equipment, and in particular to a cleaning device for a double butterfly valve of a spray tower. Background Technology

[0002] Spray towers are generally used to rapidly dry raw materials sprayed from atomizers using high-speed airflow, thereby achieving powder production. However, due to prolonged operation, the inner wall of the spray tower or the outlet often experiences wall adhesion. Therefore, an automatic cleaning device is usually installed to automatically clean the inner wall of the spray tower with high-pressure water. However, there are still cleaning dead zones. For example, the automatic cleaning device of the spray tower cannot reach the butterfly valve area for cleaning, which affects the purity of the mixed product. During material identification, the quality problem of "polycrystalline" mixture is often found. The existing method is to disassemble the outlet double butterfly valve for manual cleaning, which is time-consuming, labor-intensive, and prone to damaging the butterfly valve components. Therefore, in order to achieve quick and effective cleaning of the outlet double butterfly valve and ensure the cleaning quality to guarantee the quality of the mixed product, it is necessary to improve it.

[0008] In a preferred embodiment of this utility model, the window is a viewing window.

[0009] In a preferred embodiment of this utility model, the window and the discharge pipe are fixed together by clamps.

[0010] In a preferred embodiment of the present invention, the clamp includes a fixing bolt, a first semicircular ring and a second semicircular ring hinged together, and an interface is provided at the end of the first semicircular ring and the second semicircular ring away from the hinge point, so that the fixing bolt can be fixed through the through hole of the interface.

[0011] This utility model has the following beneficial effects:

[0012] This invention solves the problem of cleaning dead zones after cleaning by setting multiple cleaning windows between the first and second butterfly valves in the discharge pipe, and then cleaning the inside with a high-pressure water gun. This solves the problem of material agglomeration and affecting the purity of the material by setting multiple cleaning windows between the first and second butterfly valves in the discharge pipe, and then cleaning the inside with a high-pressure water gun.

[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, 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.

[0018] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] Reference Figures 1 to 2 The preferred embodiment of this utility model is as follows:

[0021] A cleaning device for a spray tower with double butterfly valves includes a tower body 1, a first butterfly valve 2 and a second butterfly valve 3 are spaced apart on the discharge pipe of the tower body 1, and a cleaning window is provided between the first butterfly valve 2 and the second butterfly valve 3.

[0022] The cleaning window includes a first window 4 and a second window 5. The first window 4 and the second window 5 include a window door 10 that can be opened and closed. When opened, the first window 4 and the second window 5 are connected to a high-pressure water gun.

[0023] This invention solves the problem of dead cleaning areas after cleaning by traditional cleaning devices, which cannot clean the butterfly valves and cause material agglomeration, thus affecting the purity of the material, by setting multiple cleaning windows between the first butterfly valve 4 and the second butterfly valve 5 in the discharge pipe and then cleaning the inside with a high-pressure water gun.

[0024] As a preferred embodiment of this utility model, it may also have the following additional technical features:

[0025] Each of the windows and doors 10 is equipped with a handle 7 for easy opening.

[0027] The window 10 and the discharge pipe are fixed with clamps 6, which facilitates disassembly and assembly by operators.

[0028] The clamp 6 includes a fixing bolt 9, a first semicircular ring and a second semicircular ring hinged together. The first semicircular ring and the second semicircular ring are provided with an interface 8 at the end away from the hinge point. The fixing bolt 9 can be fixed through the through hole of the interface 8, which is convenient for the operator to disassemble and install. A high-pressure water gun is used to clean the dead corners and improve the purity of the material.
