Description

Technical Field

[0001] The utility model belongs to the technical field of filters, and particularly relates to a raw water filter. Background Art

[0002] Raw water refers to water collected from nature, which can include natural water sources such as groundwater, reservoir water and mountain spring water. It has not undergone any artificial treatment. In a broad sense, any water before entering the water treatment process can be called raw water. Raw water usually contains impurities and therefore needs to be filtered.

[0003] During the raw water filtration process, large particles of impurities in the raw water are mostly intercepted by filters. In order to improve the filtration effect, the filters in the existing technology also use multi-layer filters for filtration. However, the filters need to be replaced and cleaned after a period of use. The filters are usually fixedly installed inside the filter and are not convenient to disassemble. At the same time, it is not convenient to remove the multi-layer filters at the same time. Usually, they can only be disassembled one by one, and the operation process is relatively cumbersome.

[0033] The connecting cover 3 is covered on the top of the barrel body 1, and a first locking component 31 is provided between the connecting cover 3 and the barrel body 1; the specific first locking component 31 includes two lock buckles 32, and the two lock buckles 32 are respectively fixedly installed on the upper parts of the front and rear sides of the barrel body 1, and the front and rear sides of the bottom of the connecting cover 3 are fixedly installed with lock tongues 33 connected to the lock buckles 32; the lock tongue 33 and the lock buckle 32 are both existing technologies, and the connection between the lock tongue 33 and the lock buckle 32 is stable, which can fix the connecting cover 3. Pressing the lock buckles 32 on both sides can release the connection with the lock tongue 33, which can facilitate the disassembly of the connecting cover 3, and when connecting, just insert the lock tongue 33 into the lock buckle 32.

[0034] An assembly rod 4 is fixedly mounted on the bottom of the connecting cover 3;

[0035] The filter plate 5 is provided with several blocks. A through hole 51 is opened in the center of the top of the filter plate 5. The filter plate 5 is slidably and sealedly connected to the assembly rod 4 through the through hole 51. A second locking assembly 52 is provided between the filter plate 5 and the assembly rod 4. The filter plate 5 is slidably and sealedly connected to the inside of the barrel body 1. The specific second locking assembly 52 includes a locking block 53. A mounting groove 54 is opened on the periphery of the assembly rod 4. The locking block 53 is slidably and sealedly assembled inside the mounting groove 54. A locking groove 55 is opened on the inner wall of the through hole 51. A spring 56 is fixedly installed on the side of the locking block 53 away from the filter plate 5. One end of the spring 56 is fixedly connected to the inner wall of the mounting groove 54, and one end of the locking block 53 extends into the locking groove 55.

[0036] A strip groove 57 is provided at the upper end of the assembly rod 4, and a strip block 58 is installed inside the strip groove 57 for sliding up and down. Several locking blocks 53 are fixedly installed with pull ropes 581 on the side away from the filter plate 5, and one end of several pull ropes 581 is fixedly connected to the strip block 58. The upper end of the strip block 58 extends out of the connecting cover 3 and is fixedly connected to a holding block 59.

[0037] In the initial state, the springs 56 are stretched to push the locking blocks 53 into the locking grooves 55, so that the filter plates 5 are fixed. The filter plates 5 are arranged up and down, and the filter air diameters of the filter plates 5 increase from bottom to top. After the filter plates 5 are fixed, the connecting cover 3 is covered on the barrel body 1 and locked using the first locking assembly 31. In this way, the filter plates 5 are all located inside the barrel body 1, and the periphery of the filter plates 5 is slidably and sealedly connected to the inner wall of the barrel body 1. When filtering water, the raw water can be filtered in multiple stages from top to bottom using multiple filter plates 5, and the filtering effect is good. When the filter plates 5 are subsequently disassembled, the connecting cover 3 can be removed directly. The dry filter plate 5 is taken out of the barrel body 1. When disassembling the filter plate 5, the staff pulls the bar block 58 to move, and the bar block 58 simultaneously pulls the several pull ropes 581 to move, and the several pull ropes 581 simultaneously pull the several locking blocks 53 into the several installation grooves 54. In this way, after the lock is released, the staff can remove all the filter plates 5. The operation is simple and convenient. During the subsequent installation, the through hole 51 opened on the filter plate 5 is aligned with the assembly stem 5 and inserted, and the locking grooves 55 opened on the several filter plates 5 are aligned with the several locking blocks 53 one by one. Then, the hand pulling the bar block 58 is released, and the several springs 56 are stretched synchronously to complete the locking of the several filter plates 5 at the same time. The operation is simple and convenient.

[0038] A handle 591 is fixedly installed at the center of the upper end of the connecting cover 3, and the gripping block 59 is located inside the handle 591; the setting of the handle 591 is convenient for the staff to take the connecting trunk 3, and the staff can also hold the gripping block 59 and pull while holding the handle 591, which is more comfortable to use.

[0039] Limiting grooves 401 are provided on both the front and rear sides of the assembly rod 4, and a limiting block 402 is fixedly installed inside the through hole 51 and is slidingly and sealingly connected to the two limiting grooves 401; the cooperation between the limiting block 401 and the limiting groove 401 makes it convenient for the staff to install the filter plate 5 and align the locking groove 55 with the locking block 53.

[0040] An activated carbon filter layer 101 is provided on the lower side of the barrel body 1; the activated carbon filter layer 101 can further enhance the filtering effect on the raw water.

[0041] The device is used as follows:

[0042] In the initial state, the plurality of filter plates 5 are all located inside the barrel body 1. When filtering raw water, the raw water enters the barrel body 1 through the water inlet pipe 11, and is filtered by the plurality of filter plates 5 from top to bottom, and then is discharged through the water outlet pipe 12. The filter plates 5 can effectively filter the particulate impurities in the raw water. When the filter plates 5 need to be replaced or cleaned later, the first locking assembly 31 is opened and the connecting cover 3 is removed. The connecting cover 3 drives the plurality of filter plates 5 to be disconnected from the barrel body 1. Then the staff pulls the holding block 59, and the bar block 58 simultaneously pulls the plurality of pull ropes 581, and the plurality of pull ropes 581 synchronously pull the plurality of locking blocks 53 into the plurality of mounting grooves 54. When the filter plates 5 are removed from the filter housing 5, the locking mechanism 52 is adjusted so that the filter plates 5 are not locked. When the filter plates 5 are removed from the filter housing 5, the locking mechanism 52 is adjusted so that the filter plates 5 are not locked. When the filter plates 5 are removed from the filter housing 5, the locking mechanism 52 is adjusted so that the filter plates 5 are not locked. When the filter plates 5 are removed from the filter housing 5, the locking mechanism 52 is adjusted so that the filter plates 5 are not locked.
