Abstract
Description
Technical field:
[0001] The utility model belongs to the field of papermaking production, in particular to a felt cleaning device for papermaking production. Background technology:
[0002] Felt is a crucial component in the papermaking industry. Papermaking felt (also known as felt) refers to the fabric used to form and transport paper. Based on their location on the papermaking machine, it can be categorized as wet felt, top felt, and dry felt. For example, wet felts, which operate under water on the papermaking machine, press the paper blanks to dehydrate them and smooth the paper surface. Wet felts offer excellent water-filtration and elasticity, high strength, minimal shrinkage, and are wear-resistant, resistant to bacteria, and resistant to acid and alkali corrosion.
[0003] During the dewatering process of the paper blank, the paper blank is laid flat on the felt cloth, and then the felt cloth is conveyed to the pressing section for dewatering. During the actual dewatering process, the felt cloth is repeatedly squeezed by the rollers in the pressing section, and a small amount of fibers in the paper blank will be squeezed onto the surface of the felt cloth. After a long period of use, a compacted area will form on the local surface of the felt cloth, causing the mesh of the felt cloth to be blocked, and the overall water permeability of the felt cloth to deteriorate, resulting in poor quality of subsequently formed paper. Therefore, the felt cloth needs to be cleaned frequently. The existing cleaning method of the felt cloth is usually that workers use a handheld water pipe to rinse the surface of the felt cloth. Although this method is simple and fast, it cannot thoroughly rinse the felt cloth, and there will still be missed areas that are not rinsed, resulting in low cleaning efficiency and poor cleaning effect. In addition, the workers' handheld water pipe flushing will cause a large amount of water resources to be wasted, which cannot be recycled and reused in time, further increasing the company's production cost investment. Utility model content:
[0004] The purpose of the utility model is to provide a felt cleaning device for papermaking production, which overcomes the shortcomings of the above-mentioned prior art and effectively solves the existing problem of low felt cleaning efficiency.
[0005] The content of the utility model: A felt cloth cleaning device for papermaking production includes a cleaning chamber, an inlet and an outlet are respectively opened on the side walls at both ends of the cleaning chamber, a conveying assembly is arranged in the cleaning chamber, the conveying assembly is used to convey the felt cloth, an upper flushing pipe and a lower flushing pipe are respectively spanned on the upper and lower sides of the felt cloth, and a plurality of nozzles are evenly installed in the extension direction on the circumferential surface of the upper flushing pipe and the lower flushing pipe.
[0006] Furthermore, the upper flushing pipe and the lower flushing pipe are connected through a diversion pipe, and a water supply pipe is connected to the diversion pipe. The water supply pipe extends outside the cleaning bin, and the input end of the water supply pipe is connected to a high-pressure water pump.
[0007] Furthermore, a return pipe is connected to the input end of the high-pressure water pump, and the outer end of the return pipe is connected to the lower end of the side wall of the cleaning bin.
[0008] Furthermore, the upper flushing pipes and the lower flushing pipes are staggered.

Specific implementation method:
[0018] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific embodiments of the present invention are now described with reference to the accompanying drawings:
[0019] like Figures 1 to 3As shown, a felt cloth cleaning device for papermaking production includes a cleaning chamber 1, on the side walls at both ends of the cleaning chamber 1 are respectively provided with an inlet 16 and an outlet 17, a conveying assembly is provided in the cleaning chamber 1, the conveying assembly is used to convey the felt cloth 2, an upper flushing pipe 3 and a lower flushing pipe 4 are respectively spanned on the upper and lower sides of the felt cloth 2, a plurality of nozzles 5 are evenly installed in the extension direction on the circumferential surface of the upper flushing pipe 3 and the lower flushing pipe 4, the upper flushing pipe 3 and the lower flushing pipe 4 are connected by a diversion pipe 6, a water supply pipe 7 is connected to the diversion pipe 6, the water supply pipe 7 extends to the outside of the cleaning chamber 1, the input end of the water supply pipe 7 is connected to a high-pressure water pump 8, and the input end of the high-pressure water pump 8 is connected to a return pipe 9, the outer end of the return pipe 9 is connected to the lower end of the side wall of the cleaning chamber 1, the upper flushing pipe 3 and the lower flushing pipe 4 are staggered, and the nozzles 5 are inclined toward the felt cloth 2.
[0020] Specifically, through the double high-pressure flushing of the upper flushing pipe 3 and the lower flushing pipe 4, both sides of the felt cloth 2 can be fully and cleanly flushed.
[0021] During actual use, the felt 2 enters the cleaning chamber 1 through the inlet 16, and the conveying assembly conveys the felt 2 to the outlet 17. During the conveying process of the felt 2, the high-pressure water pump 8 pressurizes the cleaning water and outputs it through the water supply pipe 7. The water supply pipe 7 conveys the cleaning water to the diversion pipe 6. After the diversion pipe 6 divides the cleaning water evenly, the cleaning water in the upper flushing pipe 3 and the lower flushing pipe 4 is sprayed at high pressure and in a straight line on the upper and lower surfaces of the felt 2 through a plurality of nozzles 5, thereby efficiently cleaning the felt 2.
[0022] After washing the felt 2, the water flows to the bottom of the washing chamber 1 for storage, and the return pipe 9 connected to the input end of the high-pressure water pump 8 sucks the stored water away for reuse in washing, thereby realizing the repeated recycling of the washing water and avoiding the waste of water resources;
[0023] The upper flushing pipes 3 and the lower flushing pipes 4 are staggeredly distributed, so that the upper and lower surfaces of the felt 2 can be flushed alternately and intensively, further improving the cleaning effect of the felt 2.
[0024] like Figures 1 to 3 As shown, a felt cloth cleaning device for paper production, the conveying assembly includes a first pair of rollers 10 and a second pair of rollers 11 which are respectively rotatably connected at both ends of the cleaning chamber 1, the first pair of rollers 10 and the second pair of rollers 11 are both transmission-connected to a drive motor 12, the drive motor 12 is mounted on the outer wall of the cleaning chamber 1, and an auxiliary roller 13 is arranged between the first pair of rollers 10 and the second pair of rollers 11. Both ends of the auxiliary roller 13 are rotatably connected to the side walls of the cleaning chamber 1, and a water filter tray 14 is installed in the cleaning chamber 1, and filter cotton 15 is laid on the water filter tray 14.
[0025] Specifically, the filter cotton 15 can filter impurities from the water used to wash the felt cloth 2 .
[0026] In actual use, the first pair of rollers 10 and the second pair of rollers 11 convey the felt 2 horizontally. During this period, the auxiliary rollers 13 can support the conveying felt 2, thereby ensuring that the felt 2 is conveyed along the set direction; a plurality of auxiliary rollers 13 can be arranged between the first pair of rollers 10 and the second pair of rollers 11;
[0027] After the felt 2 is cleaned, the second pair of rollers 11 can also squeeze and dehydrate it, thereby reducing the water content of the cleaned felt 2 and increasing the amount of washing water recovered;
[0028] The filter cotton 15 laid on the water filter tray 14 can filter out impurities carried in the washing water, thereby improving the cleanliness of the recycled water, so that the effect of washing the felt cloth 2 again is still better;
[0029] The top of the cleaning chamber 1 is open, which makes it easy for on-site operators to directly observe the cleaning status and adjust the cleaning status of the felt at any time.
[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
