Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of non-negative pressure water supply equipment, in particular to a non-negative pressure water supply equipment with filtering function. BACKGROUND

[0002] The non-negative pressure water supply equipment is a new type of water supply equipment. The non-negative pressure water supply equipment is a device that can utilize the original pressure of the municipal pipe network to pressurize water without generating negative pressure in the secondary water supply system, so as to meet the water demand of users.

[0003] The non-negative pressure water supply equipment is mainly based on vacuum suppression technology and flow stabilization compensation technology. When the equipment is running, through the components such as flow stabilizer and vacuum inhibitor, the residual pressure of the municipal pipe network is directly used to suck and pressurize water for supply without affecting the normal water supply of the municipal pipe network, which not only avoids generating negative pressure to the municipal pipe network, but also realizes energy-saving and efficient water supply. When the municipal pipe network has sufficient water supply pressure, the equipment automatically uses the pressure of the municipal pipe network for water supply.

[0004] As a patent with publication number CN218204702U discloses a non-negative pressure water supply equipment high-efficiency filtering device, which comprises a device bin, sliding rails, sliding blocks, a filtering bin, a connecting plate, a filtering layer, and a drainage pipe. The filtering bin can be conveniently disassembled and assembled, which facilitates the cleaning of the filtering bin by the staff, improves the filtering efficiency and filtering effect, and simultaneously, the water can be conveniently transported through the adhesion between the two rubber rings and the connecting pipe and the drainage pipe.

[0005] When filtering water, the above-mentioned patent has the problem that when the water that has been subjected to primary filtration is transported into the filtering bin through the connecting pipe, the distribution of the water flow in the filtering bin after the water flow flows out of the connecting pipe may be uneven due to the limited diameter of the connecting pipe. This may cause the water flow to be relatively concentrated in some areas of the filtering bin, while the water flow is less in some areas, and the filtering pressure borne by the filtering layer in the water flow concentrated areas is relatively large, and impurities may be more concentratedly deposited on the filtering layer in some areas, which causes the filtering layer in these areas to be blocked at a faster speed. Therefore, it is necessary to provide a non-negative pressure water supply equipment with filtering function to solve the above-mentioned problems.

[0006] It should be noted that the above information disclosed in this background section is only used to understand the background technology of the present application concept, and therefore, it can contain information that does not constitute prior art. SUMMARY

The water flow may be relatively concentrated in some areas of the filtering bin, and the water flow is less in some areas. The filtering pressure borne by the filtering layer in the water flow concentrated area is larger, and impurities may be more concentratedly deposited on the filtering layer in some areas, so that the clogging speed of the filtering layer in these areas is accelerated.

[0009] Further, a first limiting plate is installed on the water outlet pipe, the first limiting plate being arranged in abutment with the bottom of the guide plate, and a second limiting plate is installed on the water outlet pipe.

[0025] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other in the case of no conflict. The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0026] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0027] As shown in Figures 1-3 The present application provides a non-negative pressure water supply equipment with filtering function, which comprises a device bin 11, a hinged opening and closing door 13 is arranged on the device bin 11, the opening and closing door 13 is used for sealing the device bin 11, and a water inlet pipe 12 is connected at the top end of the device bin 11, the water inlet pipe 12 is used for introducing external water source into the device bin 11, and a baffle 14 is fixedly installed at both ends of the inner wall of the device bin 11, the baffle 14 is arranged obliquely, and the baffle 14 is used for guiding the water flow entering the device bin 11 from the water inlet pipe 12 to flow in a certain direction and path;

[0028] An initial filtering assembly 2 is installed inside the device bin 11, which is used for primary filtering the water flow introduced into the device bin 11, and the initial filtering assembly 2 comprises a first sliding rail 21 fixedly installed on both sides of the inner wall of the device bin 11 and at the lower end of the baffle 14, a first sliding block (not shown in the figure) is slidingly installed on the first sliding rail 21, a connecting plate 22 is fixedly installed on the first sliding block, and a filter screen 23 is connected between the two connecting plates 22, which is used for filtering larger impurities in the water flow;

[0029] A collection bin 24 is fixedly installed on one side of the filter screen 23 away from the baffle 14, which is used for collecting the initially filtered water flow, and since the first sliding block can slide along the linear direction of the first sliding rail 21, the installation and disassembly of the initial filtering assembly 2 becomes very convenient, when it is necessary to clean, replace the filter screen 23 or maintain the inside of the initial filtering assembly 2, the staff can easily slide the initial filtering assembly 2 out of the device bin 11, which is simple and fast in operation and improves the maintainability of the equipment;

[0030] In order to further filter the water flow, as Figures 3-5As shown, a fine filter assembly 3 is installed inside the device bin 11, which includes a second sliding rail 317 fixedly installed on both sides of the inner wall of the device bin 11 and at the lower end of the primary filter assembly 2, and a second sliding block 318 is slidingly installed on the second sliding rail 317 and can slide along the linear direction of the second sliding rail 317;

[0031] And a filter bin 31 is fixedly installed between the two groups of second sliding blocks 318, and the filter bin 31 has a fixed plate 34 on both sides, which is connected to the second sliding block 318 by bolts, so that the filter bin 31 can slide on the second sliding rail 317 through the second sliding block 318 to be suitable for sliding out of the device bin 11;

[0032] And a first filter layer 32 is installed at the top end of the filter bin 31 by fasteners, and a second filter layer 35 is installed at the bottom end of the filter bin 31 by fasteners, and the first filter layer 32 and the second filter layer 35 can be quartz sand filter layers, which can further remove fine impurities, colloids and the like remaining in the water flow, and improve the purity of the water quality, and a cover 33 is provided on one side of the first filter layer 32 close to the collection bin 24, when the water flow enters the cover 33 from the collection bin 24 through the telescopic pipe 25, the spatial structure of the cover 33 makes the water flow diffuse therein, slows down the water flow speed, and provides a buffer for the water flow to impact the first filter layer 32;

[0033] Meanwhile, a moving unit 36 is embeddedly installed on the cover 33, which is spliced by two groups of guide plates 37, which are crosswise arranged, and a recess (not labeled in the figure) is formed at the intersection of the two groups of guide plates 37, and a sliding groove 38 is formed on the guide plate 37, and a sliding seat 310 is slidingly installed on the sliding groove 38, and the square groove is used to provide a space for the sliding seat 310 to slide on the sliding groove 38 of the two groups of guide plates 37 arranged crosswise;

[0034] And a water outlet pipe 311 is provided through the sliding seat 310, and a long groove 39 with a diameter matching that of the water outlet pipe 311 is formed through the guide plate 37, which is used to provide a moving space for the water outlet pipe 311, and a first limiting plate 312 is fixedly installed on the water outlet pipe 311 and abuts against the bottom of the guide plate 37, and a second limiting plate 313 is also fixedly installed on the water outlet pipe 311 and abuts against the top of the guide plate 37, and the cooperation of the first limiting plate 312 and the second limiting plate 313 can prevent the sliding seat 310 from being easily pulled out of the long groove 39 when it is in the recess position;

[0035] The water outlet pipe 311 penetrates through the first limiting plate 312 and the second limiting plate 313, and is connected with the telescopic pipe 25 installed on the bottom of the collecting bin 24. One end of the telescopic pipe 25 is connected with the water outlet pipe 311. The design of the moving unit 36 enables the water outlet pipe 311 to move flexibly, avoiding the situation that the water outlet pipe 311 is fixed in a position, which causes the water flow to be relatively concentrated in some areas of the filtering bin 31. The filtering layer in the water flow concentrated area bears a larger filtering pressure, and the impurities are more concentratedly deposited on the filtering layer in some areas, which accelerates the clogging of the filtering layer in these areas.

[0036] Meanwhile, the first air cylinder 314 is fixedly installed on a group of guide plates 37. The output end of the first air cylinder 314 is fixedly installed with the first magnetic suction block 316. The first magnetic suction block 316 is adapted to move with the telescopic end of the first air cylinder 314 to contact or move away from the second limiting plate 313. The contact area between the second limiting plate 313 and the first magnetic suction block 316 is made of magnetic material. Figure 4 When the telescopic end of the first air cylinder 314 is in the limit position, the sliding seat 310 is in the position of the groove. When it is necessary to change the position of the water outlet pipe 311, the first air cylinder 314 is started to move the sliding seat 310.

[0037] The second air cylinder 315 is fixedly installed on another group of guide plates 37. The output end of the second air cylinder 315 is fixedly installed with the second magnetic suction block (not marked in the figure). The second magnetic suction block is adapted to move with the telescopic end of the second air cylinder 315 to contact or move away from the second limiting plate 313. The contact area between the second limiting plate 313 and the second air cylinder 315 is made of magnetic material. When the telescopic end of the second air cylinder 315 is in the limit position, the sliding seat 310 is in the position of the groove. When it is necessary to change the position of the water outlet pipe 311, the second air cylinder 315 is started to move the sliding seat 310.

[0038] By controlling the telescopic amount of the first air cylinder 314 and the second air cylinder 315, the position of the water outlet pipe 311 can be adjusted. Compared with manual adjustment or other simple mechanical structures, the air cylinder driven mode can realize more accurate positioning, ensuring that the water outlet pipe 311 accurately introduces the water in the collecting bin 24 into the ideal position of the filtering bin 31, further optimizing the distribution of the water flow in the filtering bin 31 and improving the filtering effect.

[0039] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Various modifications and changes can be made by those skilled in the art based on the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
