[0018] A treatment method for wastewater treatment equipment of a water jet loom, the treatment method comprising:

[0019] Introducing the wastewater of the water jet loom into the pretreatment tank;

[0020] Controlling the filter ring to rotate slowly;

[0021] Large-volume impurities in the wastewater are blocked by several groups of first filter holes;

[0022] The large-volume impurities in the wastewater follow the filter ring to rotate into the dirt collecting tank;

[0023] Pumping the pretreated wastewater from the pretreatment tank into the flocculation tank;

[0025] Filtering the water in the flocculation tank and introducing it into the water storage tank;

[0026] Completing the wastewater treatment work of the water jet loom.

[0027] The beneficial effects of the present invention are:

[0028] 1. The wastewater passes through several groups of first filter holes on the filter ring to filter out large-volume impurities. At the same time, the filter ring is controlled to rotate slowly. When the large-volume impurities on the filter ring rotate with the filter ring to the sewage collection tank, the scraper attached to the outer wall of the filter ring will scrape off the large-volume impurities and concentrate them between the scraper and the sealing plate. Subsequently, the large-volume impurities can be centrally processed by pulling out the sewage collection plate. This not only avoids the problem that large-volume impurities such as waste yarn ends and fibers are easily piled up and wound around the interception net, affecting the water flow, improves the working effect of the treatment device, but also improves the collection effect of large-volume impurities.

[0029] 2. After the wastewater is filtered through the first filter holes, it enters the interior of the filter ring. Subsequently, the remaining large-volume impurities are filtered through the second filter holes on the filter plate. At the same time, an air chamber is opened in the lifting rod, and the lifting rod is slidably connected in the installation frame, so that the lifting rod can float on the surface of the wastewater. At the same time, the capacitive oil film sensor can monitor the thickness of the oil stain on the wastewater surface in real time, and by controlling the air pump to adjust the gas density in the air chamber, the height of the lifting rod inserted into the water can be adjusted, so that the bottom inner wall of the oil collection tank is always flush with the bottom of the oil stain, facilitating the adsorption of the oil stain by the oil absorption pad and improving the oil removal efficiency of the treatment equipment.

[0030] 3. By controlling the rotation of the mounting plate, when the rotation speed reaches a corresponding level, the water resistance on several groups of stirring plates is greater than the elastic force of the compression spring, so that several groups of telescopic blocks and connecting plates squeeze the flocculant in the medicine cavity. At the same time, one end of the medicine discharge pipe moves to the outside of the rotating rod, so that the flocculant is discharged into the wastewater through the small holes on the side wall of the medicine discharge pipe after being squeezed. During this process, several groups of sliders are controlled to drive several groups of rotating rods to move outward along the central axis of the mounting plate, so that the flocculant can be evenly distributed in the wastewater, accelerating the flocculation of wastewater impurities and improving the working efficiency of the treatment equipment.

[0031] 4. The wastewater generated by the water jet loom is introduced into the pretreatment tank through the corresponding first connecting pipe and second connecting pipe. At the same time, the water used by the water jet loom is led out from the water storage tank and introduced into the water jet loom through the water supply pipe and the corresponding first connecting pipe for use. During this process, the wastewater and the purified water pass through the water inlet chamber and the water outlet chamber respectively, and the water inlet chamber and the water outlet chamber are separated by a spiral heat exchange plate, so that the heat in the wastewater can preheat the purified water used by the water jet loom, thus realizing the recovery of wastewater heat and improving the environmental protection effect of the treatment equipment.

[0046] When carrying out the wastewater treatment work of a water jet loom, first, the wastewater of the water jet loom is introduced into the pretreatment tank 3 through the water inlet and outlet mechanism 9. The large-volume impurities in the wastewater are filtered by the pretreatment mechanism 4. Subsequently, the wastewater enters the flocculation tank 5. Then, the rapid flocculation mechanism 8 is controlled to enter the wastewater, and the remaining impurities in the wastewater are flocculated by slowly releasing the flocculant and stirring. After the flocculation is completed and filtered, it is input into the water storage tank 10. Subsequently, the water in the water storage tank 10 is reintroduced into the water jet loom through the water inlet and outlet mechanism 9 to achieve the environmental protection effect of water circulation.

[0047] Exemplarily, as Figure 2 and Figure 3 shown, the pretreatment mechanism 4 includes a bottom plate 401; an installation frame 402 is provided on the top of the bottom plate 401; a filter ring 403 is provided on the top of the bottom plate 401; the filter ring 403 movably penetrates through the installation frame 402; a number of groups of first filter holes 404 are evenly distributed on the filter ring 403; a filter plate 405 is provided in the installation frame 402; a number of groups of second filter holes 406 are arranged in a rectangular array on the filter plate 405; the aperture of the second filter holes 406 is smaller than the aperture of the first filter holes 404; an oil removal component 407 is slidably connected in the installation frame 402 in the vertical direction; a capacitive oil film sensor 408 is provided on one side wall of the installation frame 402 close to the water inlet and outlet mechanism 9; a sewage collection tank 410 is provided on one side wall of the installation frame 402; a sewage collection plate 409 movably penetrates through one side wall of the installation frame 402 away from the filter plate 405; a scraping plate 411 and a sealing plate 412 are provided on one side wall of the sewage collection plate 409; the scraping plate 411 is movably attached to the outer wall of the filter ring 403.

[0048] When carrying out the wastewater treatment work of a water jet loom, the wastewater enters the pretreatment tank 3. Subsequently, the wastewater first passes through a number of groups of first filter holes 404 on the filter ring 403 to filter the large-volume impurities. At the same time, the filter ring 403 is controlled to rotate slowly. When the large-volume impurities on the filter ring 403 rotate to the sewage collection tank 410 following the filter ring 403, the scraping plate 411 attached to the outer wall of the filter ring 403 will scrape off the large-volume impurities and concentrate them between the scraping plate 411 and the sealing plate 412. Subsequently, the large-volume impurities can be centrally treated by pulling out the sewage collection plate 409. This not only avoids the problem that large-volume impurities such as waste yarn heads and fibers are prone to accumulate and entangle on the interception net, affecting the water flow, improves the working effect of the treatment device, but also improves the collection effect of the large-volume impurities.

[0049] Exemplarily, as Figure 4As shown, the oil removal component 407 includes a lifting rod 4071; an oil collecting groove 4072 is formed on a side wall of the lifting rod 4071 away from the filter plate 405; an oil absorbing pad 4073 is provided on an inner wall of the oil collecting groove 4072 close to the filter plate 405; an air cavity 4074 is formed in the lifting rod 4071; an air pump 4075 is provided at the top of the lifting rod 4071; an output end of the air pump 4075 is communicated with the air cavity 4074; a connecting rod 4076 is provided on a side wall of the lifting rod 4071 away from the filter plate 405; a cleaning plate 4077 is provided at one end of the connecting rod 4076 away from the lifting rod 4071; the cleaning plate 4077 is movably attached to an outer wall of the capacitive oil film sensor 408.

[0050] After the wastewater is filtered through the first filter holes 404, it enters the interior of the filter ring 403, and then the large-volume impurities that are missed are filtered through the second filter holes 406 on the filter plate 405. At the same time, an air cavity 4074 is formed in the lifting rod 4071, and the lifting rod 4071 is slidably connected in the mounting frame 402, so that the lifting rod 4071 can float on the surface of the wastewater. At the same time, the capacitive oil film sensor 408 can monitor the thickness of the oil stain on the wastewater surface in real time, and by controlling the air pump 4075, the gas density in the air cavity 4074 can be adjusted, so that the height of the lifting rod 4071 inserted into the water can be adjusted, so that the bottom inner wall of the oil collecting groove 4072 is always flush with the bottom of the oil stain, which is convenient for the oil absorbing pad 4073 to adsorb the oil stain and improves the oil removal efficiency of the treatment equipment.

[0051] Exemplarily, such as Figure 5 、 Figure 6 and Figure 7As shown, the rapid flocculation mechanism 8 includes a mounting plate 801; a motor 802 is provided at the top of the mounting plate 801; a plurality of groups of chutes 803 are provided at the bottom of the mounting plate 801 in an annular array; a rotating rod 804 is provided in each group of chutes 803; a chemical agent chamber 805 is provided in each rotating rod 804; a plurality of telescopic blocks 806 are movably penetrated through one side wall of each chemical agent chamber 805 at equal intervals; a stirring plate 807 is provided on one side wall of each telescopic block 806 away from the rotating rod 804; a connecting plate 808 is provided between adjacent two groups of telescopic blocks 806; a pressing spring 809 is provided on one side wall of each telescopic block 806 away from the stirring plate 807; the other end of each pressing spring 809 is connected to the corresponding inner wall of one side of the chemical agent chamber 805; a medicine discharging pipe 810 is provided on one side wall of each connecting plate 808 away from the stirring plate 807; one end of each medicine discharging pipe 810 away from the connecting plate 808 movably penetrates to the outside of the rotating rod 804; a lead screw 811 is provided in each group of chutes 803; a slider 812 is slidably connected in each group of chutes 803; each slider 812 is threadedly connected to a corresponding lead screw 811; each slider 812 is drivingly connected to a corresponding rotating rod 804; a transmission cavity 813 is provided in the mounting plate 801; the output end of the motor 802 extends into the transmission cavity 813 and is drivingly connected to a first bevel gear 814; one end of each lead screw 811 extends into the transmission cavity 813 and is drivingly connected to a second bevel gear 815; each second bevel gear 815 is meshingly connected to the first bevel gear 814.

[0052] After the wastewater is pretreated, it enters the flocculation tank 5. Subsequently, the mounting plate 801 is controlled to rotate. When the rotation speed reaches a corresponding level, the water resistance on the plurality of stirring plates 807 is greater than the elastic force of the pressing springs 809, so that the plurality of telescopic blocks 806 and the connecting plates 808 squeeze the flocculant in the chemical agent chamber 805. At the same time, one end of the medicine discharging pipe 810 moves to the outside of the rotating rod 804, so that the flocculant is discharged into the wastewater through the small holes on the side wall of the medicine discharging pipe 810 after being squeezed. During this process, the motor 802 drives the first bevel gear 814 to rotate. Under the meshing relationship between the first bevel gear 814 and the plurality of second bevel gears 815, the plurality of second bevel gears 815 drive the plurality of lead screws 811 to rotate. Under the threaded connection relationship between the plurality of lead screws 811 and the plurality of sliders 812, the plurality of sliders 812 drive the plurality of rotating rods 804 to move outward along the central axis of the mounting plate 801, so that the flocculant can be evenly distributed in the wastewater, accelerating the flocculation work of the wastewater impurities and improving the working efficiency of the treatment equipment.

[0053] Exemplarily, such as Figure 8 and Figure 9As shown, the water inlet and outlet mechanism 9 includes an interaction pipe 901; an interaction cavity 905 is formed in the interaction pipe 901; a spiral heat exchange plate 906 is arranged in the interaction cavity 905; the heat exchange plate 906 divides the interaction cavity 905 into a water inlet cavity and a water outlet cavity; a group of baffles 907 are respectively arranged at both ends of the interaction cavity 905; two groups of first connecting pipes 902 are arranged on one group of the baffles 907 away from the pretreatment tank 3; a second connecting pipe 903 is arranged on the other group of the baffles 907; the two groups of first connecting pipes 902 are respectively communicated with the water inlet cavity and the water outlet cavity; the second connecting pipe 903 is communicated with the water inlet cavity; a water supply pipe 904 is arranged on the outer wall of the interaction pipe 901; the water supply pipe 904 is communicated with the water outlet cavity.

[0054] By introducing the wastewater generated by the water jet loom into the pretreatment tank 3 through the corresponding first connecting pipe 902 and second connecting pipe 903, and at the same time, the water used by the water jet loom is led out from the water storage tank 10 and introduced into the water jet loom through the water supply pipe 904 and the corresponding first connecting pipe 902 for use. In this process, the wastewater and the purified water pass through the water inlet cavity and the water outlet cavity respectively, and the water inlet cavity and the water outlet cavity are separated by the spiral heat exchange plate 906, so that the heat in the wastewater can preheat the purified water used by the water jet loom, thus realizing the recovery of the wastewater heat and improving the environmental protection effect of the treatment equipment.

[0055] The wastewater passes through several groups of first filter holes 404 on the filter ring 403 to filter large-volume impurities. At the same time, the filter ring 403 is controlled to rotate slowly. When the large-volume impurities on the filter ring 403 rotate to the sewage collection tank 410 following the filter ring 403, the scraper 411 attached to the outer wall of the filter ring 403 will scrape off the large-volume impurities and concentrate them between the scraper 411 and the sealing plate 412. Subsequently, the sewage collection plate 409 can be pulled out for centralized treatment of the large-volume impurities, which not only avoids the problem that large-volume impurities such as waste yarn heads and fibers are easily accumulated and wound around the interception net, affecting the water body flow, improves the working effect of the treatment device, but also improves the collection effect of the large-volume impurities.

[0056] After being filtered by the first filter holes 404, the wastewater enters the inside of the filter ring 403, and then the remaining large-volume impurities are filtered through the second filter holes 406 on the filter plate 405. At the same time, an air cavity 4074 is formed in the lifting rod 4071, and the lifting rod 4071 is slidably connected in the installation frame 402, so that the lifting rod 4071 can float on the surface of the wastewater. At the same time, the capacitive oil film sensor 408 can monitor the thickness of the oil stain on the wastewater surface in real time, and adjust the gas density in the air cavity 4074 by controlling the air pump 4075, so that the height of the lifting rod 4071 extending into the water can be adjusted, so that the bottom inner wall of the oil collection tank 4072 is always flush with the bottom of the oil stain, facilitating the adsorption work of the oil absorption pad 4073 on the oil stain and improving the oil removal efficiency of the treatment equipment.

[0057] By controlling the rotation of the mounting plate 801, when the rotation speed reaches a corresponding level, the water resistance on several groups of stirring plates 807 is greater than the elastic force of the extrusion spring 809, causing several groups of telescopic blocks 806 and the connecting plate 808 to extrude the flocculant in the medicine cavity 805. At the same time, one end of the medicine discharge pipe 810 moves to the outside of the rotating rod 804, enabling the flocculant to be discharged into the wastewater through the small holes on the side wall of the medicine discharge pipe 810 after extrusion. During this process, control several groups of sliders 812 to drive several groups of rotating rods 804 to move outward along the central axis of the mounting plate 801, so that the flocculant can be evenly distributed in the wastewater, accelerating the flocculation of wastewater impurities and improving the working efficiency of the treatment equipment.

[0058] By introducing the wastewater generated by the water jet loom through the corresponding first connecting pipe 902 and the second connecting pipe 903 into the pretreatment tank 3, and at the same time, the water used by the water jet loom is led out from the water storage tank 10 and introduced into the water jet loom through the water supply pipe 904 and the corresponding first connecting pipe 902 for use. During this process, the wastewater and the purified water pass through the water inlet cavity and the water outlet cavity respectively, and the water inlet cavity and the water outlet cavity are separated by the spiral heat exchange plate 906, enabling the heat in the wastewater to preheat the purified water used by the water jet loom, thus realizing the recovery of wastewater heat and improving the environmental protection effect of the treatment equipment.
