TECHNICAL FIELD

[0001] The utility model relates to papermaking technical field, concretely is a kind of papermaking felt cleaning and use spray device. BACKGROUND

[0002] Nowadays, a large amount of water resources and wood materials are needed to be mixed in the papermaking process to produce paper pulp, and after the production of paper pulp is completed, the impurities in the paper pulp need to be adsorbed and filtered by filter felt to ensure the quality of the produced paper.

[0003] However, as the use time increases, a large amount of impurities will be adsorbed and accumulated on the felt, which will affect the filtering and adsorbing effect of the felt. Therefore, a cleaning and spraying device for the felt is born. The device filters white water introduced into the filter pipe to make the white water into clean water, and then sprays and cleans the felt. When the staff needs to replace or maintain the filter structure in the filter pipe, the valve in the filter pipe needs to be closed first, and then the filter pipe needs to be disassembled. However, even if the valve is closed first, a large amount of water will still be stored in the filter pipe. After the pipe is disassembled, the water resources will be spilled, causing waste and not meeting the concept of environmental protection development. Therefore, we propose a spraying device for cleaning papermaking felt to effectively solve the above problems. SUMMARY

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0019] Please refer to Figure 1 - Figure 4The utility model provides a kind of papermaking felt cleaning spray device, including water diversion spray system 1, water diversion spray system 1 includes several vertically arranged filter tubes 2, several filter tubes 2 are internally hollow structure, and the top end of filter tube 2 is open, and the filter assembly 3 is slidably connected in the height direction of filter tube 2 in several filter tubes 2, filter assembly 3 can slip to the outside of the top end of filter tube 2, vertically arrange filter tube 2, so that filter assembly 3 can be vertically slid in filter tube 2, when filter assembly 3 is slid to the outside of the top end of filter tube 2, it can be maintained or replaced to filter assembly 3, and the mode does not need to remove filter tube 2, to avoid the spilling of water in filter tube 2, reduce the waste of water resources, make device more environmentally friendly.

[0020] The filter assembly 3 is described in detail as follows:

[0021] The filter assembly 3 includes a filter 301 and a flow guide pipe 302, which are detachably connected by a connecting piece 303. The filter 301 and the flow guide pipe 302 are both in a tubular structure with both ends open. A filter screen 304 is detachably connected in the filter 301. The filter 301 is located above the flow guide pipe 302, so that when the filter assembly 3 is driven to move as a whole to the top end of the filter tube 2, the filter 301 will first slide to the outside of the filter tube 2. Therefore, the filter 301 can be easily detached from the flow guide pipe 302, making the maintenance and replacement of the filter 301 and the filter screen 304 more convenient and efficient.

[0022] Further, a sealing ring 305 is fixedly connected to the outer side wall of the flow guide pipe 302. The sealing ring 305 is annular, and the outer ring surface of the sealing ring 305 is sealingly connected to the inner side wall of the filter tube 2. In this way, the water in the filter tube 2 will flow into the filter 301 through the flow guide pipe 302 and will not flow away from the gap between the flow guide pipe 302 and the filter tube 2.

[0023] In this embodiment, a water outlet 201 is formed in the side wall of the filter tube 2. When the bottom end of the filter 301 slides to the top end of the filter tube 2, the sealing ring 305 slides to the same height position as the water outlet 201. In this way, when the filter 301 and the flow guide pipe 302 are both located in the filter tube 2, the water outlet 201 is in an open state, and at this time, the water can flow into another pipe through the water outlet 201. When the filter 301 and the filter screen 304 need to be detached and replaced, i.e., when the filter 301 slides to the outside of the filter tube 2, the water outlet 201 will be blocked by the sealing ring 305, so as to be closed, preventing the water in the other pipe from entering the filter tube 2 through the water outlet 201.

[0024] The driving mode provided by the application for the sliding of the filter assembly 3 is as follows:

[0025] The top end of the filtering pipe 2 is detachably connected with a top cover 202, and the top end of the filter 301 is fixedly connected with a handle 306, which is slidably penetrated through the top cover 202 along the height direction of the filtering pipe 2, so that the staff can control the movement of the whole filtering assembly 3 by pulling or pushing the handle 306.

[0026] It should be noted that the water diversion spraying system 1 further comprises a water inlet pipe and a water outlet pipe, the water inlet pipe and the water outlet pipe are connected in communication through the filtering pipe 2, and the water outlet end of the water outlet pipe is connected with a spraying mechanism to spray and clean the cloth.

[0027] The working principle and use process of the utility model are as follows: when the filter 301 or the filter screen 304 needs to be maintained or replaced, the staff can pull the filter 301 and the flow guide pipe 302 upward through the handle 306, when the sealing ring 305 moves to the position of the water outlet 201, the sealing ring 305 blocks the water outlet 201, at this time, the filter 301 moves to the outside of the filtering pipe 2, then the filter 301 is detached from the flow guide pipe 302, and the filter 301 and the filter screen 304 can be maintained or replaced.

[0028] It should be noted that, in this document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without limitation, an element preceded by "comprises... a" does not, without more constraints, foreclose the existence of additional identical elements in the process, method, article, or apparatus.

[0029] Although the embodiments of the utility model have been shown and described, it should be understood by those of ordinary skill in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
