Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to an energy-saving device for producing spunlace nonwoven fabrics. Background Art

[0002] High-pressure fine water flow is sprayed onto one or more layers of fiber webs to entangle the fibers of the fiber webs with each other, thereby reinforcing the fiber webs and giving them a certain strength. The fiber fabric produced by this method is spunlace non-woven fabric. Spunlace non-woven fabric feels very soft and fluffy, has strong moisture absorption capacity, and also has a certain oil absorption capacity. It is often used in medical curtains, surgical gowns, dressing materials, etc. It has different properties and effects according to the different fibers used in weaving. When producing spunlace non-woven fabrics, non-woven fabric production equipment is required to spray water on the fiber webs fed in. In order to reduce production costs, energy-saving devices are used to recycle the water used in production. The energy-saving device recycles the sprayed water flow, filters it, and then pumps it into the production equipment for spraying again. The energy-saving device can greatly reduce the water consumption in the production of spunlace non-woven fabrics and effectively save production costs.

[0003] Although the above-mentioned existing technology can solve the corresponding technical problems, it still has certain defects: when the existing energy-saving device is in use, since the recycled water flow will contain some fibers, it is necessary to filter the water flow through a built-in filter cover. After a period of use, a large amount of fiber attachments are likely to appear on the filter cover, which will make the water flow not smooth and unable to return enough water for injection. The entire production line needs to be shut down and the energy-saving device disassembled for cleaning. Not only is the cleaning very complicated and cumbersome, but it also affects the production efficiency of the spunlace non-woven fabric. Utility Model Content

[0004] The utility model aims to provide an energy-saving device for producing spunlace nonwoven fabrics with simple cleaning and high water return efficiency in view of the defects and shortcomings of the prior art.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an energy-saving device for the production of spunlace non-woven fabrics, comprising a main unit and a recovery pipe arranged on one side of the main unit and connected to the main unit, a reflux pipe connected to the main unit is arranged at the other end of the main unit, the main unit comprises a closed shell and a first pumping pipe penetrating the closed shell and connected to the recovery pipe, a removable filter is detachably provided in the closed shell, a drop block is slidably fitted on one side of the removable filter close to the first pumping pipe, a pull rope extending to the outside of the closed shell is connected to the top of the drop block, when the surface of the removable filter is clogged by adhesion, the pull rope is released to allow the drop block to fall freely and scrape and clean the attachments on the surface of the removable filter.

[0006] A further improvement is that: the closed shell is also penetrated by a second water pumping pipe connected to the return pipe.

[0007] A further improvement is that: a fixing ring is further provided at one end of the pull rope away from the falling block, and a fixing bolt which is detachably and slidably provided on the inner wall of the fixing ring and is nailed into the outer wall of the closed shell.

[0008] A further improvement is that the sinking block includes a gravity block with a top connected to the end of the pull rope and a shovel head arranged below the gravity block, and the side wall of the gravity block is attached to the side of the disassembly filter screen close to the first water pumping pipe.

[0009] A further improvement is that a fixing ring which is wound and connected with the end of the pull rope is also provided on the top of the gravity block.

[0010] A further improvement is that the top outer wall of the gravity block is also provided with a plurality of closed circles.

[0011] A further improvement is that: a guide groove is provided on the side wall of the disassembly filter screen, and a positioning protrusion that slides relative to the inner wall of the guide groove is also provided on the side of the gravity block close to the disassembly filter screen.

[0012] A further improvement is that: the bottom of the detachable filter screen is also provided with a snap-fit ​​block which is detachably embedded in the bottom surface of the inner wall of the closed shell.

[0013] A further improvement is that a lifting handle is provided above the disassembly filter.

[0014] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: after the utility model is used for a period of time, if attachments are generated on the disassembled filter screen, the sinking block can be loosened, so that the gravity block of the sinking block drives the shovel head to scrape the disassembled filter screen from top to bottom under the action of its own gravity, so that the attachment layer can be quickly cleaned, thereby reducing the difficulty of cleaning. At the same time, when the blockage is too serious, the disassembled filter screen can be quickly pulled up and removed, and replaced. The cleaning speed is fast and simple, the required downtime is short, the return water efficiency is high, and the production efficiency of the spunlace non-woven fabric is guaranteed.

When an impurity adhesion layer is generated on the surface of the disassembled filter 12 and the pass rate is reduced, the sinking block 15 can be pressed down and the pull rope 16 can be loosened to make the sinking block 15 slide freely along the surface of the disassembled filter 12, and the gravity block 151 made of high-density materials such as iron can be used to make it fully fall, and cooperate with the shovel head 154 is attached to the surface of the disassembled filter 12 to fully scoop up the attached matter, and after sliding down, the sinker 15 is pulled up again by the pull rope 16 to repeatedly scrape the surface of the disassembled filter 12, thereby fully removing the impurities attached to the surface of the disassembled filter 12. The cleaning can be performed during use without stopping the machine, which reduces the difficulty of cleaning. If there are too many attached matters, the detachable disassembled filter 12 can be quickly pulled out of the closed shell 11 and replaced. The disassembly and cleaning can be completed with only a short stop time. The required stop time is short, the water return efficiency is high, and the production efficiency of the spunlace non-woven fabric is guaranteed;

[0030] Working principle of the utility model: When the utility model is used, the water flow after use of the spunlace textile machine is connected to the recovery pipe 2, and the return pipe 3 is connected to the spunlace textile machine. At this time, the used water can be pumped into the closed shell 11 through the first pumping pipe 13, and after passing through the disassembled filter 12, the impurities contained in it are filtered, and enter the return pipe 2 to be re-sent into the spunlace textile machine for repeated use. When an impurity adhesion layer is generated on the surface of the disassembled filter 12, resulting in a decrease in the passing rate, the sinker 15 can be pressed down at this time, and the pull rope 16 can be loosened to allow the sinker 15 to slide freely along the surface of the disassembled filter 12, passing through high-density iron and other materials. The gravity block 151 made of high-density material can make it fall fully, and cooperate with the shovel head 154 to fit the surface of the disassembled filter 12 to fully shovel up the attachments. After sliding down, the sinker 15 is pulled up again by the pull rope 16 to repeatedly scrape the surface of the disassembled filter 12, so that the impurities attached to the surface of the disassembled filter 12 are fully removed. The machine can be cleaned during use without stopping the machine, which reduces the difficulty of cleaning. If there are too many attachments, the detachable disassembled filter 12 can be quickly pulled out of the closed shell 11 and replaced. The disassembly and cleaning can be completed with only a short stop. The required downtime is short, the return water efficiency is high, and the production efficiency of the spunlace non-woven fabric is guaranteed.
