Description

Technical Field

[0001] The invention relates to the technical field of down processing equipment, and in particular to down wastewater treatment equipment. Background Art

[0002] During the production of down, the raw materials need to be washed with water. Phosphorus-free feather detergent and deodorant are added during the washing process to remove grease, dust and odor. After initial washing, cleaning and multiple rinsing, the down and feather pieces are cleaned. Down industrial wastewater is mainly produced by water washing machines (initial washing, cleaning, rinsing) and centrifugal separators (dehydration). The drainage method is intermittent, and the concentrations of initial washing water, cleaning water and rinsing water of different times are quite different. The initial washing wastewater has a large pollution load because it contains more animal fat, protein, sand, feces, finely crushed down, a small amount of detergent and deodorant, etc., but the biodegradability of the wastewater is good. In the washing process, with repeated rinsing, the concentration of pollutants in the washing wastewater continues to decrease. The impurities in the last one or two washing wastewaters are relatively few, which has reached the national emission standards.

[0003] Most of the existing wastewater discharge equipment used in the down processing process will adopt the mixed discharge treatment of the wastewater from the three processes of initial washing, cleaning and rinsing. However, in the initial washing process of down, a large amount of water is consumed, and the wastewater contains more pollutants. If all the wastewater is discharged, with the continuous production and processing of down, more water resources are consumed, and the production cost also increases accordingly. Based on the needs of energy saving and environmental protection, and also in order to reduce production costs, the wastewater will be filtered and reused in some processing steps. However, since the wastewater contains animal fats, proteins, sand, feces, finely divided down, a small amount of detergents and deodorants, etc., the filter frame or filter element structure responsible for filtering impurities is very easy to be blocked during the filtration process, resulting in a decrease in the working efficiency of the wastewater treatment process. Therefore, the present application provides a down wastewater treatment equipment to meet the needs. Summary of the invention

[0004] In response to the above problems, the present application provides a down wastewater treatment device.

DETAILED DESCRIPTION

[0029] 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.

[0030] Example 1: Reference Figure 1-4 The down wastewater treatment equipment shown in the figure, in the process of down processing, the industrial wastewater generated is mainly produced by the washing machine centrifugal separator, the drainage method is intermittent, and the concentrations of the initial washing water, cleaning water and rinsing water of different times are quite different. The initial washing wastewater contains more animal fat, protein, sand, feces, finely shredded down, a small amount of detergent and deodorant, etc., and the pollution load is large, but the biodegradability of the wastewater is good.

[0031] In order to reduce pollutants in the cleaning wastewater and enable the cleaning wastewater to be recycled, the device includes a wastewater receiving pool 1 for receiving wastewater, a guide plate 2 for guiding the flow of wastewater and a filter screen 3 arranged obliquely below the guide plate 2 are arranged in the wastewater receiving pool 1, two synchronously rotatable first drive shafts 21 are arranged on the guide plate 2 along its inclined direction, and a plurality of rotatable interception racks 22 are arranged on the first drive shaft 21, and the interception racks 22 are all in a comb-tooth structure. The wastewater flowing along the inclined surface of the guide plate 2 passes through the interception rack 22 and the filter screen 3, and then flows out from the bottom of the wastewater receiving pool 1.

[0032] The combination of the interception frame 22 and the filter screen 3 can implement graded treatment of impurities and pollutants of different volumes in the wastewater, reduce the content of pollutants in the wastewater, improve the quality of wastewater treatment operations, and facilitate the recycling of wastewater.

[0033] After the wastewater passes through the drainage plate 2, it falls toward the end of the filter screen 3 close to the drainage plate 2 under the action of gravity. Therefore, the pollutants intercepted by the filter screen 3 are concentrated and accumulated on the part of the filter screen 3 close to the drainage plate 2. In order to prevent the accumulation of pollutants on this part and block the filter screen 3, a transfer scraper 4 capable of transferring pollutants is provided at the end of the filter screen 3 close to the drainage plate 2, and the center of the filter screen 3 is recessed downward to form a receiving portion 31 capable of receiving pollutants.

[0034] A rotatable second drive shaft 5 is provided in the storage portion 31 , and a plurality of equidistantly arranged guide plates 6 are provided on the second drive shaft 5 . When the second drive shaft 5 and the guide plates 6 rotate synchronously, the transfer scraper 4 can move toward the storage portion 31 until the pollutants fall into the inner side of the storage portion 31 .

[0035] like Figure 5 As shown, two adjacent interception racks 22 on the first drive shaft 21 are in a vertical distribution state, and the drainage plate 2 is provided with a plurality of comb-tooth grooves corresponding to the interception racks 22. In a natural state, the interception racks 22 exposed above and below the drainage plate 2 are perpendicular to the drainage plate 2, and the remaining interception racks 22 correspond to the comb-tooth grooves. When the wastewater flows through the surface of the drainage plate 2, the comb-tooth-shaped interception racks 22 can intercept the impurities inside it, and can collect the larger impurities in the wastewater.

[0036] The first drive shaft 21 is connected to the side wall of the wastewater receiving tank 1 through a bearing seat, and two power wheels 23 coaxially distributed with the first drive shaft 21 are arranged outside the wastewater receiving tank 1. The two power wheels 23 are connected through a first synchronous belt 24, and a motor 1 for controlling its rotation is arranged on one of the power wheels 23. When the motor 1 is running, under the connection of the first synchronous belt 24, the two power wheels 23 can be made to rotate synchronously, so as to achieve the purpose of driving the two groups of interception frames 22 to rotate synchronously.

[0037] During the rotation process, the interception frame 22 can switch its relative position with the drainage plate 2, so that the impurities originally located on one side of the interception frame 22 are transferred, and the interception frame 22 originally corresponding to the comb groove is rotated to the top of the drainage plate 2 as a substitute, so that the staff can centrally clean the feather impurities. The cleanliness of the interception frame 22 is guaranteed, and there is no need to repeatedly replace the interception frame 22, which saves human resources.

[0038] like Figure 6-8 As shown, the second drive shaft 5 is connected to the side wall of the wastewater receiving tank 1 through a bearing seat. A driving wheel 51 coaxially distributed with the second drive shaft 5 is provided on the outside of the wastewater receiving tank 1. A motor 2 for controlling its rotation is provided on the driving wheel 51. When the second drive shaft 5 is located in the receiving portion 31 and rotates, the guide plate 6 turns over the pollutants in the receiving portion 31, which can improve the smoothness of the receiving portion 31, avoid the pollutants accumulated inside the receiving portion 31 from clogging the receiving portion 31, and leave space for the sewage in the pollutants to fall.

[0039] The top of the transfer scraper 4 is provided with an extension frame 41 which can move synchronously therewith, and the extension frame 41 is provided with a pair of connecting seats 42 facing the side walls of the wastewater receiving tank 1, and the connecting seats 42 are provided with guide blocks 43 extending to the outside of the wastewater receiving tank 1, and the wastewater receiving tank 1 is provided with a channel that can accommodate the sliding of the guide block 43.

[0040] like Figure 6-8 As shown, the end of the guide block 43 exposed to the outside of the wastewater receiving tank 1 is provided with a traction arm 44, and a roller group 48 is provided outside the wastewater receiving tank 1 to guide the traction arm 44 to move linearly. The traction arm 44 is provided with a transversely distributed tooth group 45, and a driving gear 46 meshing with the tooth group 45 is provided outside the wastewater receiving tank 1. When the driving gear 46 rotates, the tooth group 45 meshing therewith can be moved, so as to achieve the purpose of driving the guide block 43, the connection seat 42, the extension frame 41 and the transfer scraper 4 to move synchronously.

[0041] A driven wheel 47 that can rotate synchronously with the driving gear 46 is provided on one side thereof, and the driven wheel 47 is connected to the driving wheel 51 through a second synchronous belt 52. Under the connection of the second synchronous belt 52, when the second driving shaft 5 and the driving wheel 51 rotate synchronously, the driven wheel 47 also rotates synchronously therewith, so as to achieve the purpose of driving the driving gear 46 to rotate. As the second driving shaft 5 and the driving wheel 51 rotate to a certain number of circles, the guide plate 6 can repeatedly flip the pollutants in the storage portion 31, and the driving gear 46 can also rotate a certain number of circles, thereby ensuring the moving range of the tooth set 45 and the traction arm 44, so that the transfer scraper 4 can smoothly move a certain range on the filter screen 3, and transfer the pollutants accumulated on the filter screen 3 to the inside of the storage portion 31.

[0042] Since the guide plate 6 has previously turned over the pollutants in the receiving portion 31, the smoothness of the receiving portion 31 can be improved, and a gap is formed inside the receiving portion 31 to accommodate the pollutants falling into it, so that the sewage remaining inside the pollutants falling into the receiving portion 31 can be drained out.

[0043] After the pollutants accumulated on the filter screen 3 are transferred to the inside of the storage part 31, when the second drive shaft 5 and the driving wheel 51 rotate in the opposite direction, under the connection of the second synchronous belt 52, the driven wheel 47 and the driving gear 46 also rotate in the opposite direction until the transfer scraper 4 returns to its original position, so as to facilitate the subsequent pollutant transfer operation. During the reverse rotation of the second drive shaft 5 and the driving wheel 51, the guide plate 6 can flip the pollutants in the storage part 31 again, increase the speed of the sewage in the pollutants falling, reduce the water content in the pollutants, and improve the efficiency of the sewage treatment operation.

[0044] Embodiment 2: Based on embodiment 1, Figure 6-8 As shown, as the wastewater treatment time increases, pollutants inside the storage part 31 continue to accumulate. In order to timely treat the accumulated pollutants and maintain the unobstructed state of the storage part 31, a storage tray 7 is provided in the gap between two adjacent guide plates 6. The top of the storage tray 7 is exposed above the filter screen 3. As pollutants inside the storage part 31 continue to accumulate, some pollutants may fall into the storage tray 7. In addition, when the guide plate 6 flips the pollutants inside the storage part 31, some pollutants are also transferred to the storage tray 7.

[0045] The tops of the multiple receiving trays 7 are connected by connecting arms 8, and a frame is provided on the wastewater receiving tank 1, which extends to the top of the connecting arms 8, and a cylinder 9 is provided on the frame to control the synchronous lifting and lowering of the connecting arms 8 and the receiving trays 7. With the rotation of the guide plate 6, the pollutants are continuously transferred to the inside of the receiving tray 7. When the receiving tray 7 is in a fully loaded state, the operation control system can control the cylinder 9 to operate, prompting the connecting arms 8 and the receiving tray 7 to rise synchronously until the receiving tray 7 is moved out to the outside of the wastewater receiving tank 1, so that the pollutants inside the receiving tray 7 can be centrally cleaned.

[0046] When the pollutants inside the receiving tray 7 are cleaned, the output force of the cylinder 9 can move it into the gap between the two adjacent guide plates 6 again to continue receiving the pollutants transferred from the receiving section 31. Continuous pollutant transfer operations can be implemented, thereby ensuring the smooth flow of the receiving section 31 and improving the work efficiency of the pollutant treatment operation.

[0047] Since comb-tooth grooves are provided on the drainage plate 2, when a large amount of wastewater flows through the surface of the drainage plate 2, it is inevitable that wastewater will fall through the gap between the comb-tooth grooves and the interception frame 22. In order to properly handle the falling wastewater and enable it to be smoothly discharged from the wastewater receiving tank 1, a receiving plate 11 is provided in the wastewater receiving tank 1. The receiving plate 11 is parallel to the drainage plate 2 and is located directly below the drainage plate 2. The wastewater falling through the comb-tooth grooves on the drainage plate 2 can fall along the surface of the receiving plate 11, pass through the filter screen 3, and flow out through the bottom of the wastewater receiving tank 1.

[0048] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
