Description

Technical Field

[0001] The utility model belongs to the technical field of reflux pumps, and in particular relates to a pipeline filtering structure and a reflux pump for wastewater treatment. Background Art

[0002] In the wastewater treatment process, return pumps, as a key piece of equipment, undertake the crucial task of transporting treated wastewater or sludge from one treatment unit to another. With increasingly stringent environmental standards and advancements in wastewater treatment technology, the performance requirements for return pumps are also increasing. Especially when treating wastewater containing large amounts of suspended solids, particulate matter, or impurities, return pumps must not only possess efficient and stable conveying capabilities but also possess effective filtration mechanisms to prevent impurities from entering the pump body and affecting its normal operation and service life.

[0003] Traditional reflux pumps for wastewater treatment often use a filter structure installed at the water inlet for filtration. However, the filter will also become clogged after a long period of filtration, so the filter needs to be cleaned. However, during the cleaning process, the reflux pump needs to be shut down, which reduces the efficiency of wastewater treatment. It is difficult to quickly clean impurities on the reflux pump filter in the existing technology, and it is difficult to ensure the operation of the reflux pump during cleaning, thereby reducing the reflux pump's efficiency in cleaning wastewater.

[0028] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0029] See Figures 1 to 6 The embodiment of the present utility model provides a pipeline filtering structure, including a mounting shell 208, a first cleaning box 201, and a second cleaning box 202. The mounting shell 208 has a cavity inside that matches the first cleaning box 201 and the second cleaning box 202, and the two ends of the mounting shell 208 are respectively provided with a liquid inlet and a liquid outlet. The mounting shell 208 is provided with two mounting openings 209 that match the first cleaning box 201 and the second cleaning box 202, and the two mounting openings 209 are arranged opposite to each other. This technical solution sets up the first cleaning box 201 and the second cleaning box 202, and the two oppositely arranged mounting openings 209 can alternately use the first cleaning box 201 and the second cleaning box 202 for filtering and cleaning operations without stopping the machine. This design ensures the continuity and efficiency of wastewater treatment and avoids production interruptions caused by stopping the machine for cleaning.

[0030] Each of the first and second cleaning boxes 201, 202 includes a cylindrical body that fits within the interior cavity of the mounting housing 208. A filter screen 207 is provided at one end of the cylindrical body, covering one end of the cylindrical body. When installing the first and second cleaning boxes 201, 202, the ends of the cylindrical bodies where the filter screen 207 is located are oriented toward the liquid outlet, allowing filtered material to accumulate in the first and second cleaning boxes 201, 202.

[0031] The first cleaning box 201 and the second cleaning box 202 are equipped with a docking mechanism, which includes a guide plate 205 and a guide groove 206, which are respectively installed on the outer side walls of the first cleaning box 201 and the second cleaning box 202. The docking mechanism docks the first cleaning box 201 and the second cleaning box 202 by using the guide plate 205 and the guide groove 206 respectively provided on the first cleaning box 201 and the second cleaning box 202. The docking mechanism can be used to bring the first cleaning box 201 / the second cleaning box 202 into the second cleaning box 202 / the first cleaning box 201 when the first cleaning box 201 / the second cleaning box 202 is withdrawn, thereby facilitating the operation. The first cleaning box 201 and the second cleaning box 202 are connected by a sliding connection, making the cleaning process simple and quick. The operator can easily slide the cleaning box to be cleaned by simply using the handle to remove impurities.

[0032] The first cleaning box 201 and the second cleaning box 202 are both provided with handles 204 on their outer side walls away from the docking mechanism. The handles 204 facilitate installation operations.

[0033] A limit assembly 3 is mounted on the edge of at least one mounting opening 209 of the mounting housing 208, and a limit groove 203 is provided on each of the first cleaning box 201 and the second cleaning box 202 to cooperate with the limit assembly 3. The provision of the limit assembly 3 allows for quick attachment or removal of the first cleaning box 201 and the second cleaning box 202, thereby improving the efficiency of cleaning impurities within the first cleaning box 201 and the second cleaning box 202.

[0034] Specifically, the limiting assembly 3 includes several limiting parts that cooperate with the limiting groove 203, and the limiting parts include a fixing rod 303 and an installation rod 302. The fixing rod 303 and the installation rod 302 both have one end movably connected to the edge of the installation port 209 on the installation shell 208, and the fixing rod 303 and the installation rod 302 can enter or be pushed out of the limiting groove 203 by rotation.

[0035] Specific forms and coordination of the fixing rod 303 and the mounting rod 302: The fixing rod 303 and the mounting rod 302 are correspondingly arranged, and the mounting rod 302 is constructed in a tubular shape. A limiting rod 304 is disposed within the mounting rod 302, and a sliding groove 301 is defined on the side wall of the mounting rod 302 away from the limiting groove 203. The sliding groove 301 is communicated with the inner cavity of the mounting rod 302. A slider 306 is disposed within the sliding groove 301, which is fixedly connected to the limiting rod 304. The free end of the fixing rod 303 is defined with a slot 305 that cooperates with the limiting rod 304. When the fixing rod 303 and the mounting rod 302 are rotated until the rod bodies enter the limiting groove 203, the free ends of the fixing rod 303 and the mounting rod 302 face each other, and one end of the limiting rod 304 can be inserted into the slot 305. During operation, the limiting rod 304 is controlled by moving the slider 306 to insert or exit the slot 305.

[0036] The inner cavity of the mounting rod 302 is also equipped with a return spring 307, which abuts against the end of the limiting rod 304 away from the free end of the mounting rod 302. The return spring 307 is used to reset the limiting rod 304, which can ensure stable and reliable docking when the fixing rod 303 and the mounting rod 302 are docked.

[0037] The locking lever 302 is locked and the locking lever 303 is unlocked, and the locking lever 302 is unlocked, so that the locking lever 302 is unlocked.

[0038] Usage process: When it is necessary to clean the impurities inside the first cleaning box 201, push the slider 306 to move the limiting rod 304 out of the slot 305, thereby releasing the fixation of the mounting rod 302 and the fixing rod 303. At the same time, rotate the mounting rod 302 and the fixing rod 303 to the outside of the limiting slot 203, thereby releasing the fixation of the first cleaning box 201 or the second cleaning box 202. At this time, slide the first cleaning box 201 upward, thereby driving the second cleaning box 202 to slide into the interior of the mounting shell 208. The second cleaning box 202 performs the filtering operation, and the first cleaning box 201 is slid out from the upper end of the second cleaning box 202 for cleaning. Conversely, when it is necessary to clean the impurities inside the second cleaning box 202, the first cleaning box 201 is slid downward, thereby driving the first cleaning box 201 to slide to the inside of the mounting shell 208, and the first cleaning box 201 performs the filtering operation, and the second cleaning box 202 is slid out from the lower end of the first cleaning box 201 for cleaning. Impurities can be cleaned without stopping the machine.

[0039] See Figures 1 to 7 The embodiment of the present invention further provides a reflux pump for wastewater treatment, including a pump body 102 , wherein the liquid inlet end of the pump body 102 is provided with a pipeline filtering structure, and the liquid outlet of the mounting shell 208 is connected to the liquid inlet end of the pump body 102 .

[0040] The pump body 102 and the power source 101 are fixed on the base 1, and the power source 101 drives the pump body 102 to work. The power source 101 can be an electric motor or an internal combustion engine.

[0041] The above description is intended to be illustrative rather than restrictive, and those skilled in the art may make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present disclosure. Furthermore, the above examples (or one or more of them) may be used in combination with each other, and it is contemplated that these embodiments may be combined with each other in various combinations or permutations.
