Description

Technical Field

[0001] This utility model belongs to the field of shielded pumps, and specifically relates to a filter shielded pump. Background Technology

[0002] During operation, the canned motor pump continuously draws liquid into the pump body. As the liquid is drawn in, sand, gravel, aquatic plants, and other impurities in the water may enter the pump body along with the liquid flow, causing damage to the internal components of the pump body and affecting the normal use of the canned motor pump. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a filter shielded pump.

[0004] The purpose of this utility model can be achieved through the following technical solution: a filter shielding pump, including a pump body, an inlet pipe and an outlet pipe, characterized in that an inlet ring is provided inside the inlet pipe, a plurality of connecting rods are provided on the outer ring of the inlet ring, a plurality of blocking rods for hanging aquatic plants are provided on both sides of the connecting rods, and a set of railings is also provided on the inner ring of the inlet ring.

[0005] The water inlet pipe is equipped with a filter plate for filtering sand and gravel. The filter plate has a number of filter holes and a blocking plate for blocking sand and gravel.

[0006] The water inlet pipe is provided with mounting grooves at both the top and bottom ends, the barrier bar is provided with mounting part one for cooperating with the mounting groove, and the filter plate is provided with mounting part two at both the top and bottom ends.

[0007] In the aforementioned filter shielded pump, an isolation section is provided between the first mounting section and the second mounting section.

[0008] In the aforementioned filter shielded pump, the baffle plate is inclined upwards from below the filter plate along the direction of the water inlet ring, and a second filter hole that communicates with each other is provided between the baffle plate and the filter plate.

[0009] In the aforementioned filter shielding pump, the first mounting part is connected to the isolation part by bolts, and the second mounting part is connected to the isolation part by bolts.

[0010] Compared with existing technologies, this filter-shielded pump uses a barrier bar to intercept aquatic plants and filter sand and gravel through filter plates and baffles, greatly reducing the possibility of aquatic plants and sand and gravel entering the pump body.

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figure 1 As shown, this filter shielded pump includes a pump body 1, an inlet pipe 2 and an outlet pipe 3. An inlet ring 4 is provided inside the inlet pipe 2. Several connecting rods 5 are provided on the outer ring of the inlet ring 4. Several blocking rods 6 for hanging aquatic plants are provided on both sides of the connecting rods 5. A set of railings is also provided on the inner ring of the inlet ring 4.

[0017] The inlet pipe 2 is equipped with a filter plate 7 for filtering sand and gravel. The filter plate 7 has several filter holes 8 and a blocking plate 9 for blocking sand and gravel.

[0018] The water inlet pipe 2 has mounting grooves 10 at both the top and bottom. The barrier bar is provided with mounting part 11 for cooperating with the mounting groove 10. The filter plate 7 is provided with mounting part 2 12 at both the top and bottom.

[0019] When the canned pump is operating, water enters the pump body 1 through the inlet pipe 2. During this process, since the aquatic plants are mostly strip-shaped or fluffy, they will entangle or hang on the barrier bar when passing through it. Smaller sand and gravel in the water float above the larger sand and gravel. Some of the smaller sand and gravel will pass over the barrier plate 9 and be blocked by the filter hole 8. The larger sand and gravel will be intercepted by the barrier and accumulate downwards along the oblique direction of the barrier. The smaller sand and gravel will also be intercepted by the filter hole 14.

[0020] When there is too much sand or aquatic plants, the filter plate 7 and the inlet ring 4 can be removed from the mounting groove 10 through the mounting part 2 12 and the mounting part 1 11, cleaned, and then reinstalled for continued use.

[0021] Preferably, an isolation part 13 is provided between the first mounting part 11 and the second mounting part 12 to separate the barrier bar from the filter plate 7.

[0022] Preferably, the baffle plate 9 is inclined upward from below the filter plate 7 along the direction of the water outlet pipe 3, and filter holes 14 that are interconnected are opened between the baffle plate 9 and the filter plate 7.

[0023] Preferably, the mounting part 11 and the isolation part 13 are connected by bolts, and the mounting part 2 12 and the isolation part 13 are connected by bolts.

[0024] Preferably, the isolation section 13 has the same shape as the mounting groove 10.

[0025] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0026] Although this document frequently uses terms such as pump body 1, inlet pipe 2, outlet pipe 3, connecting rod 5, barrier rod 6, filter plate 7, filter hole one 8, baffle plate 9, mounting groove 10, mounting part one 11, mounting part two 12, isolation part 13, and filter hole two 14, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
