Description

TECHNICAL FIELD

[0001] The present invention relates to the field of filtration technology, and in particular to a large water volume special filter cleaning system suitable for aquaculture sites. BACKGROUND

[0002] According to the process of breeding fish and poultry, in order to ensure the healthy growth of breeding products, filters are installed to maintain clean water supply. The filter with adsorptive filter material can filter out impurities before entering the clean water tank to maintain good water quality. This filter is different from the water purifier for human drinking, which is a large water volume filter.

[0003] As shown in Figure 9 , 10 , it is the current filter system for aquaculture; basically, the raw water source 70 passes through a switch 71 to send the raw water to the water inlet 81 on the upper side of the filter barrel 80, and then passes through the filter material in the filter barrel 80 for filtration, flows through the horizontally extending water collecting pipes 83 of the lower water collecting head 82, and is sent to the clean water outlet 84 of the lower water collecting head 82. The filtered clean water is sent out from the clean water outlet 84.

[0004] In order to clean the filter barrel 80, the water inlet 81 of the filter barrel 80 is temporarily closed, and the water source enters the filter barrel 80 in the reverse direction through the clean water outlet 84 to perform reverse washing operation on the internal filter material (not shown in the figure). After cleaning, the water inlet 81 of the raw water inlet of the filter barrel 80 is reopened, and the filtration operation process of the raw water continues. However, the prior art structure has the following problems:

[0005] 1. The water source used in the reverse washing operation is unfiltered raw water, and the impurities in the raw water are trapped in the small pores of the wall of the horizontally extending water collecting pipes 83 distributed around the lower water collecting head 82 of the filter barrel 80, so that the filter barrel 80 cannot be effectively cleaned, and the cross-sectional area of the clean water passing through is reduced due to the blockage of the pores of the water collecting pipes 83 in the subsequent raw water filtration process, which seriously affects the normal filtration of the clean water.

[0006] 2. If large water volume filtration is required, only the filter barrel 80 can be increased, and a set of control valve switches is required for each filter barrel 80, so the cost of the control valve switches for the water source inlet and outlet of each filter barrel 80 is multiplied.

[0007] 3. Because the water collecting pipes 83 around the lower water collecting head 82 are horizontally extended at a fixed angle, the lower side of the filter barrel 80 is concave, so the radial space is reduced, and the outer diameter range formed by the lower water collecting head 82 and the water collecting pipes 83 may have difficulty in installation of different shapes of filter barrels 80. SUMMARY

[0008] The present invention provides a filter cleaning system for large water volume, comprising at least one raw water pump for pumping raw water from a predetermined water source;

[0009] The present invention provides a filter cleaning system for large water volume, comprising at least one raw water pump for pumping raw water from a predetermined water source;

[0010] The present invention provides a filter cleaning system for large water volume, comprising at least one raw water pump for pumping raw water from a predetermined water source;

[0011] The present invention provides a filter cleaning system for large water volume, comprising at least one raw water pump for pumping raw water from a predetermined water source;

[0012] The present invention provides a filter cleaning system for large water volume, comprising at least one raw water pump for pumping raw water from a predetermined water source;

[0013] Therefore, the present invention can provide the following effects:

[0014] 1. In the normal filtration process, since each stirring filter barrel is connected to the raw water input pipe in parallel through the raw water shunt pipe, the raw water input pipe is connected to the raw water pump, so that the amount of filtered water can be greatly increased in a unit of time, and the efficiency of filtered water is higher.

[0015] 2、The present application has better cleaning effect on the reverse washing of the stirring filter barrel. The reverse switch valve, the reverse transmission pipe and the reverse transmission pipe which are connected in parallel are connected to a sewage discharge pipe, so that when any stirring filter barrel is washed, the filtered clean water output by other stirring filter barrels is sent to the stirring filter barrel to be cleaned, and the filter material is washed in reverse. Since the filtered clean water is used for cleaning, the impurities in the clean water are much lower than those in the raw water, so the impurities and dirt remaining in the water collecting pipe and the filter material during the cleaning process are greatly reduced, and the cleaning effect is more ideal.

[0016] 3、A universal joint is installed between the lower water collecting head and the water collecting pipe distributed equidistantly on the side, so that the water collecting pipe can be pivoted in three-dimensional direction to adjust the position. When the inner end face of the stirring filter barrel chamber is concave, the water collecting pipe can be pulled to change the position relative to the seat body to reduce the outer diameter of the lower water collecting head, so as to adapt to smaller chamber space. Compared with the fixed direction form of the water collecting pipe fixed horizontally in the prior art, the present application has the function of elastic adjustment according to the size of the installation space.

DETAILED DESCRIPTION

[0029] The present application is a filter cleaning system for large water volume, please refer to Figure 1 which comprises a raw water pump 10, at least two groups of stirring filter barrels, the number of stirring filter barrels is configured, the present application can have two groups or three groups or five groups or more, the first preferred embodiment is taken as an example of three groups, which are defined as a first stirring filter barrel 20, a second stirring filter barrel 201, and a third stirring filter barrel 202.

[0030] Please refer to Figure 1As shown, the present application mainly adopts parallel form for the pipeline configuration of the raw water pump 10 and the first, second and third stirring filter barrels 20, 201 and 202. The first, second and third stirring filter barrels 20, 201 and 202 are respectively provided with a raw water on-off valve 21, a reverse on-off valve 22 and a clean water output port 23 at the upper side. The raw water pump 10 is connected with a raw water input pipe 11. The raw water input pipe 11 is connected with a raw water shunt pipe 12, 121 and 122 corresponding to the first, second and third stirring filter barrels 20, 201 and 202. The raw water shunt pipe 12, 121 and 122 is connected to the raw water on-off valve 21 of the first, second and third stirring filter barrels 20, 201 and 202. When the raw water on-off valve 21 is opened, the raw water input by the raw water input pipe 11 can be evenly shunted to the first, second and third stirring filter barrels 20, 201 and 202. A clean water output manifold 13 is further provided. The clean water output manifold 13 is connected with a clean water on-off valve 131 at the end. The clean water output manifold 13 is connected with a clean water output branch pipe 14, 141 and 142 corresponding to the clean water output port 23 of the first, second and third stirring filter barrels 20, 201 and 202 along the way. The clean water output branch pipe 14, 141 and 142 is connected to the clean water output port 23 of the first, second and third stirring filter barrels 20, 201 and 202. The clean water output branch pipe 14, 141 and 142 is used for sending the filtered clean water of the first, second and third stirring filter barrels 20, 201 and 202 to the clean water output manifold 13. The clean water on-off valve 131 is used for controlling the opening and closing of the clean water delivery. A sewage discharge pipe 15 is further provided for discharging and backwashing sewage. The sewage discharge pipe 15 is connected with the reverse on-off valve 22 of the first, second and third stirring filter barrels 20, 201 and 202. The sewage discharge pipe 15 is connected with a reverse transmission pipe 16, 161 and 162 corresponding to the reverse on-off valve 22 of the first, second and third stirring filter barrels 20, 201 and 202.

[0031] Please refer to Figure 1 , 2As shown, the structures of the first, second, and third stirred filter tanks 20, 201, and 202 are all the same. Taking the first stirred filter tank 20 as an example, the structures of the second and third stirred filter tanks 201 and 202 are similar and will not be described further. The first stirred filter tank 20 contains a chamber 200 for filtration. A raw water inlet 211 communicating with the chamber 200 is located on one side of the upper part of the chamber. A wastewater outlet 212 communicating with the chamber 200 is located adjacent to the raw water inlet 211. The first stirred filter tank 20 also includes a stirring unit 24, filter media 26 for water filtration filled in the communicating chamber 200, and a water collection head 30. The raw water inlet 211 is used to connect to the raw water switch valve 21. Wastewater outlet 212 is connected to a reverse switching valve 22. The stirring unit 24 set on the top side of the first stirring filter tank 20 includes a motor 241 fixedly set on the top side. The rotatable output shaft 242 of the motor 241 extends into the chamber 200 of the first stirring filter tank 20. An agitator 25 is fixedly connected in the chamber 200. The agitator 25 is, for example, a blade assembly. During the backwashing operation, it works with the motor 241 to drive the agitator 25 to rotate, thereby agitating the filter media 26 and removing debris from the filter media 26. The lower water collection head 30 is installed below the chamber 200 of the first stirring filter tank 20 at its clean water outlet 23.

[0032] The next episode's water head is 30, as follows: Figure 2 , 3As shown in Figure 4, it includes a base 31 in the shape of a disc, a water inlet pipe 32 disposed at the top of the base 31, and several water collection pipes 36 connected to the periphery of the base 31. The water inlet pipe 32 of the base 31 is inverted L-shaped, and one end is connected to the water outlet 23 of the first stirring filter tank 20. The base 31 is connected to each water collection pipe 36 by a universal joint 33, so that the water collection pipes 36 can pivot relative to each other. The universal joint 33 includes a ball bearing seat 34 and a ball joint 35. The ball bearing seat 34 is recessed at equal intervals around the periphery of the base 31 in a hemispherical shape. The ball joint 35 has a spherical end embedded in the ball bearing seat 34, which can pivot at multiple angles. The other end of the ball joint 35 forms a mating surface 351 with an internal thread. Therefore, one end of the water collection pipe 36 is correspondingly set as a mating end 36 with an external thread. 1. The water collection pipe 36 is threaded onto the mating surface 351, and a cover 37 is threaded onto the end of the water collection pipe 36. When the cover 37 is removed, the water collection pipe 36 can be further cleaned. The water collection pipe 36, which is used to cover the cover 37, is connected to the ball joint 35. The water collection pipe 36 can then use the ball joint 35 with the ball bearing 34 as the fulcrum to adjust the angle of the three-dimensional pivot. If the inner end face of the first stirring filter tank 20 chamber 200 is arc-shaped, and there may not be enough space for the water collection pipe 36 to extend horizontally outward relative to the seat 31, part or all of the water collection pipe 36 can be moved to extend upward relative to the seat 31, reducing the outer diameter of the entire lower water collection head 30 to adapt to the small internal space of the chamber 200 or the arc-shaped change of the inner end face, so that the lower water collection head 30 can be smoothly placed in the chamber 200 of the first stirring filter tank 20.

[0033] First, install the lower water collection head 30 in the first, second, and third stirring filter tanks 20, 201, and 202 below the chamber 200, connecting the purified water pipe 32 to the purified water outlet 23. Then, fill in the filter media 26 and install the stirrer 25 to complete the process. Next, assemble the aforementioned first, second, and third stirring filter tanks 20, 201, and 202 with the raw water inlet pipe 11. Figure 1 The aforementioned piping configuration allows for the assembly of this invention.

[0034] Please refer to the following: Figure 1 , 2To illustrate the effectiveness of this invention: First, in the normal filtration process, the purified water switch valve 131 is opened, each raw water switch valve 21 is opened, and each reverse switch valve 22 is closed. The raw water pump 10 is started, supplying raw water through the raw water inlet pipe 11 to the raw water diversion pipes 12, 121, and 122 corresponding to the first, second, and third stirred filter tanks 20, 201, and 202, allowing the raw water to enter the chambers 200 of the first, second, and third stirred filter tanks 20, 201, and 202. Since the raw water is diverted from the raw water inlet pipe 11 into three raw water diversion pipes 12, 121, and 122, the first, second, and third stirred filter tanks can be ensured to operate smoothly. The filtration volume of the stirred filter tanks 20, 201, and 202 is relatively even. Raw water enters the chambers 200 of the first, second, and third stirred filter tanks 20, 201, and 202. After being filtered layer by layer by the filter media 26, the purified water enters the base 31 through the gaps of the water collection pipes 36 of the lower water collection head 30. It is then sent out through the purified water outlet 23 via the purified water pipe 32 to the purified water outlet branch pipes 14, 141, and 142. The purified water then flows downward through the purified water outlet branch pipes 14, 141, and 142 and collects in the purified water outlet manifold 13. Finally, it is released to the destination where purified water is needed via the purified water switch valve 131.

[0035] After a period of use, the first, second, and third mixing and filter tanks 20, 201, and 202 need to be cleaned. For example, if the first mixing and filter tank 20 needs to be cleaned... Figure 2 , 5 As shown, the purified water switch valve 131 is closed, the reverse switch valve 22 of the first stirred filter tank 20 is opened, and the raw water switch valve 21 of the first stirred filter tank 20 is closed. The second and third stirred filter tanks 201 and 202 do not need to be changed; that is, the raw water switch valves 21 of the second and third stirred filter tanks 201 and 202 are open as normal during the filtration process, and the reverse switch valves 22 of the second and third stirred filter tanks 201 and 202 are closed as normal during the filtration process. Because the activation of the reverse switch valve 22 of the first stirred filter tank 20 creates a reverse flow, allowing the purified water in the second and third stirred filter tanks 201 and 202 to flow naturally. The purified water output branch pipes 141 and 142 converge into the purified water output manifold 13. From the purified water output manifold 13, the water is delivered to the purified water output branch pipe 14 of the first stirring filter tank 20, enters the purified water output port 23, and flows into the water collection pipe 36, filling the filter media 26 inside the first stirring filter tank 20. Simultaneously, the stirring unit 24 is activated, causing the stirrer 25 to agitate the filter media 26. This agitation and agitation of the filter media 26 in a purified water environment allows impurities and cleaning wastewater to be sent out through the wastewater outlet 212 and the reverse transmission pipe 16, flowing downwards to the wastewater discharge pipe 15. The wastewater is then discharged through the wastewater discharge pipe 15. After the wastewater is discharged, as... Figure 1 Close the reverse switch valve 22 of the first stirring filter tank 20 and open the raw water switch valve 21 of the first stirring filter tank 20 to return to normal filtration.

[0036] Similarly, the second mixing filter tank 201 needs to undergo a backwash cleaning process for the filter media 26, as follows: Figure 2 , 6 As shown, the purified water switch valve 131 is opened, the reverse switch valve 22 of the second stirred filter tank 201 is opened, and the raw water switch valve 21 of the second stirred filter tank 201 is closed. The raw water switch valves 21 and reverse switch valves 22 of the first and third stirred filter tanks 20 and 202 remain unchanged as in normal filtration. That is, the raw water switch valves 21 of the first and third stirred filter tanks 20 and 202 are open, and the reverse switch valves 22 are closed. Purified water is input into the second stirred filter tank 201 through the first and third stirred filter tanks 20 and 202 for backwashing. After backwashing the filter media 26, the sewage and debris are sent to the sewage discharge pipe 15 through the reverse transmission pipe 161 of the second stirred filter tank 201 and discharged.

[0037] like Figure 2 , 7 As shown, to clean the third mixing filter tank 202, open the purified water switch valve 131, open the reverse switch valve 22 of the third mixing filter tank 202, and close the raw water switch valve 21 of the third mixing filter tank 202. The raw water switch valves 21 and reverse switch valves 22 of the first and second mixing filter tanks 20 and 201 remain unchanged as in normal filtration. Purified water is input from the first and second mixing filter tanks 20 and 201 into the third mixing filter tank 202 for backwashing. After backwashing the filter media 26, the sewage and debris are sent to the sewage discharge pipe 15 through the reverse transmission pipe 162 of the third mixing filter tank 202 and discharged.

[0038] For example Figure 8 The illustrated embodiment demonstrates the invention's dual configuration of first and second stirring filter tanks 20 and 201. For example, when the first stirring filter tank 20 needs to clean the filter media 26, clean water is reverse-flowed into the first stirring filter tank 20 for cleaning. After backwashing the filter media 26, the wastewater and debris are discharged through the reverse transmission pipe 16 of the first stirring filter tank 20 to the wastewater discharge pipe 15. Conversely, when the second stirring filter tank 201 needs to clean the filter media 26, clean water is output from the first stirring filter tank 20 to the second stirring filter tank 201 for cleaning. Wastewater is sent through the reverse transmission pipe 161 to backwash the filter media 26, and then the wastewater and debris are discharged through the reverse transmission pipe 161 of the second stirring filter tank 201 to the wastewater discharge pipe 15.
