Technical Field

[0001] The utility model relates to the technical field of water treatment equipment, and more specifically, to a blockage alarm device for a pipeline direct drinking water pre-treatment filtering system. Background Art

[0002] The piped drinking water system uses a central water purification process to deeply treat tap water. The water quality meets the user's drinking and national requirements, and is transported to the water point through an independent pipe network for users to drink. At present, the central water purification process mainly treats tap water deeply, among which the pre-treatment purification equipment plays a vital role as the first barrier to water production. The main measures of the pre-treatment purification equipment of the central water purifier for piped drinking water on the market are to use pp cotton, quartz sand, activated carbon, etc. to remove impurities, SS, residual chlorine, and some organic matter in the water. However, when the pre-treatment purification equipment for piped drinking water performs preliminary filtration on the water, the pre-treatment system device often becomes blocked after running for a period of time, and it is difficult to detect, resulting in idling of the water supply equipment of the back-end membrane treatment system, and the water output of the entire system is very low, and even the membrane booster pump motor is damaged. Therefore, this scheme proposes a pre-treatment system blockage alarm device to solve the above problems. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a blockage alarm device for a pipeline direct drinking water pre-treatment filtration system, which has the advantage of being able to effectively and timely discover pipeline blockage problems.

[0008] As a preferred technical solution of the utility model, a one-way valve facing the inside of the pipeline is provided at the hole.

[0009] As a preferred technical solution of the utility model, the water pipe and the pipe of the post-filtering system close to the filter box are both detachable pipes fixedly connected.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown, the utility model provides a blockage alarm device for a pipeline direct drinking water pretreatment filtration system, comprising a fixed water pipe 1, a manual valve 8 is fixedly connected to the upper end of the fixed water pipe 1, a low-pressure switch 2 is fixedly connected to the right end of the fixed water pipe 1, a circuit pipe 9 is fixedly connected to the rear side of the low-pressure switch 2, a PLC control system 10 is fixedly connected to the middle of the circuit pipe 9, a water pipe 3 is fixedly connected to the right side of the low-pressure switch 2, a pre-filtering system 4 is fixedly connected to the right side of the water pipe 3, a filter box 5 is fixedly connected to the right side of the pre-filtering system 4, a post-filtering system 6 is fixedly connected to the right end of the filter box 5, a booster pump 7 is fixedly connected to the rear end of the post-filtering system 6, a filter gun pipe 11 is fixedly connected to the upper end of the filter box 5, a cover 12 is inserted at the top end of the filter gun pipe 11, and a hole 13 is provided at the connection between the post-filtering system 6 and the booster pump 7.

[0021] Direct drinking water is generally domestic water that is directly consumed after being filtered and treated to meet drinkable standards. The filter layer of direct drinking water usually contains sand, gravel, and activated carbon, which needs to be replaced after long-term use. At this time, closing the low-pressure switch 2 through the PLC control system 10 can facilitate replacement and can detect the water pressure through the low-pressure switch 2 to determine whether blockage occurs.

[0022] The filter gun pipe 11 is inclined above the filter box 5 , and the inclined direction of the filter gun pipe 11 is close to the booster pump 7 .

[0023] When there is a rough blockage inside the pipe, the pipe can be flushed in the reverse direction by high-pressure water flow to achieve the purpose of unclogging the pipe.

[0024] The pre-filter system 4 has a honeycomb filter mesh inside.

[0025] The large impurities that may appear before the water enters the filtration treatment process are reduced in advance, and the situation where the filter box 5 may need to be replaced is reduced, which is convenient for reducing costs.

[0026] Among them, a switch identical to the low-pressure switch 2 is provided above the post-filter system 6 and is connected to the PLC control system 10 through a circuit conduit 9 for control.

[0027] The unified monitoring operation is performed through the PLC control system 10, which reduces manual labor, releases labor and reduces labor costs.

[0028] Among them, a one-way valve facing the inside of the pipeline is provided at the hole 13.

[0029] It is beneficial to maintain the pressure in the pipeline and keep the internal pressure stable.

[0030] The water pipe 3 and the pipe of the post-filtration system 6 close to the filter box 5 are both detachable pipes fixedly connected.

[0031] When the filter gun pipe 11 is too blocked to be cleaned, it is easy to disassemble and repair, which effectively reduces the time for repair and replacement and improves work efficiency.

[0032] The working principle and use process of this utility model:

[0033] When it is necessary to treat water, the PLC control system 10 receives a water production signal and turns on the low-pressure switch 2. The water flows through the fixed water pipe 1 into the pre-treatment system for filtration and purification. The low-pressure switch 2 detects whether the water pressure meets the water inlet requirements. The water filtered and purified by the pre-treatment system enters the pre-filter system 4 through the water pipe 3 to filter out large impurities, and then enters the filter box 5 to complete the filtration treatment. The booster pump 7 starts to supply water to the rear-end treated water. The switch at the upper end of the post-filter system 6 detects whether the purified water meets the water absorption requirements of the booster pump 7. If the pressure is lower than the set value, the post-filter system 6 will sound an alarm. After receiving the signal, the PLC control system 10 turns off the booster pump 7 and the post-filter system 6 for maintenance. If it cannot be turned off, the fixed water pipe 1 is manually closed. The cover 12 can be opened to rinse the interior with high-pressure water to prevent rough blockage. Then test the water pressure. If it is still lower than the set value, the low-pressure switch 2 and the post-filter system 6 are disassembled for replacement and maintenance.
