Description

Technical Field

[0001] The invention relates to the technical field of printing and dyeing, and in particular to a printing and dyeing wastewater resource utilization mechanism. Background Art

[0002] The multi-stage treatment of printing and dyeing wastewater is a complex process, which usually includes multiple stages such as pretreatment, biochemical treatment, deep treatment and sludge treatment to ensure that the wastewater meets environmental protection standards and requirements before discharge or reuse. In the pretreatment stage, the large floating objects and suspended matter in the wastewater, such as cotton yarn, fiber scraps, etc., are removed through the action of the grid to protect the subsequent treatment equipment from clogging. As the first line of defense for wastewater treatment, the grid can effectively intercept and remove large floating objects, suspended matter, fiber scraps, cotton yarn and other solid impurities in the wastewater. If these impurities are not removed, they may clog the subsequent treatment equipment, such as water pumps, pipes, valves, etc., and affect the normal operation of the entire wastewater treatment system. Through the interception effect of the grid, the load of the subsequent treatment equipment (such as regulating tanks, coagulation sedimentation tanks, biochemical reaction tanks, etc.) can be reduced, their service life can be extended, and maintenance costs can be reduced. At the same time, the grid can also prevent solid impurities from causing wear and clogging of aeration equipment, agitators, etc.

[0003] However, there are still a lot of suspended matter in the printing and dyeing wastewater. It is sometimes difficult to completely clean the suspended matter in the printing and dyeing wastewater using a grid alone, because the suspended matter may appear in the form of tiny particles, colloids, etc. in the wastewater, which is difficult to remove directly by gravity sedimentation. For this reason, the wastewater needs to be filtered at multiple stages to treat the suspended matter in the wastewater. At present, the most common equipment that can both filter and filter the suspended matter is the filter net. The multi-stage filter net treats the wastewater. Among them, there is still the problem of suspended matter clogging the filter net when filtering the wastewater. Some of the suspended matter is in a gelatinous state. When the filter net is cleaned, it is easy to cause the gelatinous suspended matter to pass through the filter net, causing the suspended matter to mix with the wastewater again. Summary of the invention

[0004] The purpose of the present invention is to provide a printing and dyeing wastewater resource utilization mechanism to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a printing and dyeing wastewater resource utilization mechanism, comprising a treatment pool, wherein a water inlet and a water outlet are respectively provided on both sides of the treatment pool, wherein the treatment pool has multiple layers of partitions for partitioning the treatment pool, wherein the treatment pool is partitioned into multiple cavities by the multiple layers of the partitions, wherein a circle of support rings are fixed on the inner walls of the multiple cavities, and a filter rack is clamped on the support rings;

[0006] The multiple layers of the partitions are provided with connection holes, which are used to transmit wastewater. The connection holes on the partitions are arranged one above and one below. The two connection holes on the side and the water inlet and the water outlet are also arranged one above and one below. The filter rack divides the cavity into two parts, one above and one below.

[0007] When the wastewater flows, it passes through the plurality of filter racks in an "S" shape.

[0008] Furthermore, the water inlet and the water outlet are located on the same straight line, and when the wastewater enters and exits the water inlet and the water outlet, the treatment pool is filled with wastewater.

[0009] Furthermore, a processing part is provided in the processing pool and penetrates the processing pool horizontally, and the processing part includes two shafts that penetrate the processing pool and the partition horizontally, and the position where the shaft penetrates is in a sealed setting, and a motor for driving the shaft to rotate is fixed on one side of the processing pool;

[0010] The two shafts are respectively located on the upper and lower sides of the filter frame, and a horizontal axis is fixed on the outer walls of the two shafts. Support ends are fixed at the ends of the horizontal axis. The horizontal axes on the upper and lower shafts are alternately arranged, and the support ends at the upper and lower ends are alternately squeezed with the filter of the filter frame.

[0011] Furthermore, a protective cover is sleeved on one end of the two shafts, and a gear is arranged inside the protective cover, so that the two shafts rotate in opposite directions through the action of the gear.

[0012] Furthermore, the support end is a rounded metal, and the support end is used to squeeze the filter screen to cause the filter screen to deform.

[0013] Furthermore, the four corners of the filter rack extend upward to be flush with the upper end surface of the treatment tank, and a support cover is detachably fixed to the upper end of the treatment tank, and the support cover supports the four corners of the filter rack.

[0014] Furthermore, the interior of the shaft body is hollow, and one end thereof is connected to the interior. A water pump is fixed to the outside of the treatment pool. A transmission pipe is connected between the water pump and the shaft body for supplying gas to the interior of the shaft body. A water outlet slot connected to the interior is opened on the outer wall of the shaft body. The water outlet slot is located in the cavity, and the water outlet slot is located on the side of the filter screen frame where water flows out.

[0015] Furthermore, a transmission pipe is also fixed between the water pump and the treatment tank, so that the water pump can transmit the filtered wastewater into the shaft body.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] 1. With multiple cavities and connecting holes distributed up and down, wastewater passes through the multi-layer filter rack in an "S" shape. The treatment pool can be filled with wastewater, so that suspended matter is positioned as much as possible in the wastewater on the inlet side of the filter rack to avoid adhering to the filter screen of the filter rack, avoiding suspended matter from passing through the filter screen of the filter rack, and making the wastewater that is subsequently filtered have relatively less suspended matter.

[0018] 2. The wastewater is in a stable state after passing through the connecting hole, which prevents a large amount of suspended matter from accumulating on the filter frame and filter screen, and prevents the filter frame and filter screen from being blocked. The suspended matter filtered out gradually increases, so that the suspended matter remains in the wastewater and is prevented from being dispersed by external forces.

[0019] 3. The upper and lower support ends squeeze the filter screen at intervals, causing the filter screen to deform up and down. The suspended matter on both sides of the filter screen is pushed outward, and the suspended matter floats in the wastewater, reducing adhesion to the filter screen, and the filter screen frame maintains the filtering effect.

[0020] 4. The water outlet spouts water outwards under the action of the water pump, and the filter rack filters the water inlet side outwards with a water pushing effect, so that the suspended matter adhering to the filter screen of the filter rack is pushed away by the water, thus maintaining the filtering effect of the filter rack.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 7 The present invention provides a technical solution: there are still a lot of suspended matter in the printing and dyeing wastewater. It is sometimes difficult to completely clean the suspended matter in the printing and dyeing wastewater by using a grid alone, because the suspended matter may appear in the form of tiny particles, colloids, etc. in the wastewater, which is difficult to remove directly by gravity precipitation. Therefore, it is necessary to filter the wastewater in multiple stages to treat the suspended matter in the wastewater. When the wastewater is filtered, the suspended matter will adhere to the filter screen and block the filter screen. When the filter screen is cleaned, the suspended matter may disperse and pass through the filter screen, resulting in mixing into the wastewater. It becomes more difficult to clean the suspended matter again. Therefore, a printing and dyeing wastewater resource utilization mechanism is required, including a treatment pool 1, and two sides of the treatment pool 1 are respectively provided with The water inlet 11 and the water outlet 12, the wastewater enters from the water inlet 11 and flows out from the water outlet 12, wherein the treatment tank 1 is similar to a sedimentation tank, the wastewater in the treatment tank 1 flows slowly, so that the suspended matter in the wastewater is prevented from being dispersed, and the treatment tank 1 has multiple layers of partitions 2 for partitioning the treatment tank 1, and the treatment tank 1 is separated into multiple cavities 4 by the multiple layers of partitions 2, and a circle of support rings 3 are fixed on the inner walls of the multiple cavities 4, and a filter rack 5 is clamped on the support ring 3, and the filter rack 5 can be taken outward, and when taking out the filter rack 5, it is only necessary to lift the filter rack 5 upward, and then clean the suspended matter blocked by the filter rack 5, so as to avoid excessive suspended matter causing wastewater to be difficult to circulate;

[0032] like Figure 6As shown, the multi-layer partitions 2 are all provided with connection holes 21, and the connection holes 21 are used to transmit wastewater. The connection holes 21 on the partitions 2 are distributed one up and one down, and the two connection holes 21 on the side and the water inlet 11 and the water outlet 12 are also distributed one up and one down. The filter rack 5 divides the cavity 4 into two parts, upper and lower. When the wastewater enters the treatment tank 1 and moves in the treatment tank 1, the wastewater will pass through the connection holes 21, move between different partitions 2, and also pass through the multi-layer filter rack 5, leaving the suspended matter in front of the filter rack 5 of the upper layer, so as to realize multi-stage filtration of the wastewater;

[0033] like Figure 6 As shown, when the wastewater flows, it passes through multiple filter racks 5 in an "S" shape. When the wastewater passes through the multi-stage filter racks 5, it passes in an "S" shape, but the wastewater is in a horizontal movement as a whole, moving from one side of the treatment tank 1 to the other side of the treatment tank 1. The laterally distributed filter racks 5 are convenient for removal and cleaning of residual suspended matter.

[0034] like Figure 3 As shown, the water inlet 11 and the water outlet 12 are located on the same straight line. When the wastewater enters and exits the water inlet 11 and the water outlet 12, the treatment pool 1 is filled with wastewater, and the wastewater moves from the water inlet 11 to the water outlet 12. The wastewater moves horizontally, and the wastewater keeps the water body as calm as possible to avoid breaking up the suspended matter.

[0035] like Figure 4 As shown, a processing part 6 is provided in the processing pool 1 and penetrates the processing pool 1 transversely. The processing part 6 includes two shafts 61 that penetrate the processing pool 1 and the partition 2 transversely. The position where the shaft 61 penetrates is in a sealed setting. A motor 7 for driving the shaft 61 to rotate is fixed on one side of the processing pool 1. The motor 7 drives the shaft 61 to rotate.

[0036] The two shaft bodies 61 are respectively located at the upper and lower sides of the filter frame 5. A transverse shaft 63 is fixed on the outer wall of the two shaft bodies 61. The ends of the transverse shaft 63 are fixed with support ends 64. The transverse shafts 63 on the upper and lower shaft bodies 61 are alternately arranged. The upper and lower support ends 64 are alternately squeezed with the filter screen of the filter frame 5. Figure 4 As shown, the filter frame 5 is in a separated state, which facilitates the clear observation of the filter frame 5 and the inside of the treatment tank 1. When the shaft body 61 rotates, the horizontal axis 63 and the support end 64 also rotate, so that the support end 64 squeezes the filter screen of the filter frame 5, as shown in FIG. Figure 5 As shown, the filter screen is deformed, and the upper and lower sides of the interval are pushed to make the suspended matter adhering to the filter screen move outward to avoid clogging the filter screen;

[0037] It should be noted that if Figure 2 and Figure 3 As shown, the filter screen is hidden to facilitate viewing of the internal structure of the treatment tank 1. Figure 1 As shown, a filter mesh frame 5 is hidden, and the support ring 3 is exposed.

[0038] like Figure 4 As shown, one end of the two shaft bodies 61 is sleeved with a protective cover 62, which is used to protect the internal gears to prevent the internal gears from being exposed to the outside. The protective cover 62 has gears inside, and the two shaft bodies 61 rotate in opposite directions through the gear action. The shaft bodies 61 rotating in opposite directions can make the upper and lower support ends 64 push the filter screen of the filter frame 5 at intervals, so that the filter screen moves up and down to push away the suspended matter.

[0039] like Figure 5 As shown, the support end 64 is a rounded metal, and the support end 64 is used to squeeze the filter screen to deform the filter screen. The main function of the support end 64 is to push the filter screen to make the filter screen produce an undulating motion, and the rounded shape prevents the filter screen from being scratched.

[0040] like Figure 2 As shown, the four corners of the filter frame 5 extend upward and are flush with the upper end surface of the treatment tank 1. A support cover 13 is detachably fixed to the upper end of the treatment tank 1. The support cover 13 supports the four corners of the filter frame 5 and limits the filter frame 5 to prevent the filter frame 5 from moving during the ups and downs of the filter. After the support cover 13 is removed, the filter frame 5 can be disassembled.

[0041] like Figure 4 and Figure 7 As shown, the interior of the shaft body 61 is hollow, and one end thereof is connected to the interior. A water pump 8 is fixed to the outside of the treatment pool 1. A transmission pipe 9 is connected between the water pump 8 and the shaft body 61 for transmitting gas to the inside of the shaft body 61. A water outlet slot 65 connected to the interior is opened on the outer wall of the shaft body 61. The water outlet slot 65 is located in the cavity 4, and the water outlet slot 65 is located on the side of the filter screen of the filter rack 5 where water flows out. Under the action of the water pump 8, the water outlet slot 65 discharges water outward, and the water outlet slot 65 rotates with the shaft body 61, and has a thrust against the filter screen of the filter rack 5, so that the suspended matter on the water inlet side of the filter rack 5 moves outward, ensuring that the suspended matter is separated from the filter screen.

[0042] like Figure 4 As shown, a transmission pipe 9 is also fixed between the water pump 8 and the treatment tank 1, and is used for the water pump 8 to transmit the filtered wastewater to the shaft body 61, so that the wastewater can be repeatedly filtered to further reduce the amount of suspended matter in the wastewater.

[0043] The working principle of the present invention is as follows: the printing and dyeing wastewater enters the treatment tank 1 from the water inlet 11 , passes through the multi-layer filter mesh frame 5 and the partition plate 2 , and moves out from the water outlet 12 through the connecting hole 21 .

[0044] First, after the wastewater enters the treatment tank 1, it passes through the multiple cavities 4 and the connecting holes 21 distributed up and down, so that the wastewater is in an "S" shape and passes through the multi-layer filter rack 5, so that the suspended matter is left on the water inlet side of the previous filter rack 5 as much as possible. The multi-layer filtration can filter the wastewater more thoroughly, and the position of the water inlet 11 and the water outlet 12 is horizontal, so that the inside of the treatment tank 1 can be filled with wastewater. When the wastewater is in the treatment tank 1 and passes through the connecting holes 21, it remains relatively stable, so that the suspended matter is as much as possible in the wastewater on the water inlet side of the filter rack 5 to avoid being completely adhered to the filter screen of the filter rack 5, so as to avoid causing the suspended matter to pass through the filter screen of the filter rack 5, so that the suspended matter in the wastewater that is subsequently filtered is relatively small.

[0045] Secondly, in the treatment pool 1 filled with wastewater, when the wastewater flows, the wastewater passes through the connecting hole 21 and is in a stable state. The suspended matter on the water inlet side of the filter frame 5 will not move in a large range, thereby avoiding the accumulation of a large amount of suspended matter on the filter screen of the filter frame 5 and clogging the filter screen of the filter frame 5. Secondly, the suspended matter filtered out gradually increases, so that the suspended matter remains in the wastewater, and the suspended matter is prevented from being dispersed by external forces. Excessive suspended matter is subsequently manually cleaned and the suspended matter is removed.

[0046] Secondly, during the operation of the motor 7, the horizontal axis 63 and the support end 64 rotate, so that the upper and lower support ends 64 squeeze the filter screen of the filter frame 5 at intervals, causing the filter screen to produce an up and down deformation effect, and the suspended matter on both sides of the filter screen is pushed outward, so that the suspended matter floats in the wastewater, reducing adhesion to the filter screen, so that the filter frame 5 maintains the filtering effect, and the suspended matter floats away in the wastewater, and the suspended matter will not be subjected to excessive force and dispersed, so as to keep the suspended matter intact.

[0047] In addition, a water outlet slot 65 for discharging water is provided on the outer side of the shaft body 61, so that the water outlet slot 65 sprays water outward under the action of the water pump 8, and the water outlet slot 65 is located in the waste water in the cavity 4. At the same time, the water outlet slot 65 is also located on the side of the filter mesh frame 5 that filters out the waste water. When the shaft body 61 rotates and the water outlet slot 65 sprays water, the water outlet slot 65 rotates, and the filter mesh of the filter mesh frame 5 has a water movement effect, and the side of the filter mesh frame 5 that filters water outward has a water pushing effect, so that the suspended matter adhered to the filter mesh of the filter mesh frame 5 is pushed away by the water, and the filtering effect of the filter mesh frame 5 is maintained.
