Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, specifically to a dual-coupling sludge suction sand machine. Background Technology

[0002] Sludge suction pumps are used in various water plants to remove sludge, sand, and other debris from water tanks. Existing sludge suction pump designs only have outlet coupling; the inlet is directly connected to the sludge suction pump. When the amount of sediment at the bottom of the tank is large, the pump tilts under stress, causing outlet coupling failure and resulting in a high failure rate.

[0003] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a dual-coupling mud and sand suction machine that can effectively avoid the impact of pump body force displacement on water output, thus making the operation more reliable.

[0005] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0006] A dual-coupling mud and sand suction machine, comprising:

[0007] A mud suction sand pump, wherein an inlet coupling mechanism is provided between the inlet of the mud suction sand pump and the inlet pipe, and an outlet coupling mechanism is provided between the outlet of the mud suction sand pump and the outlet pipe.

[0008] The outlet coupling mechanism includes a first connecting plate disposed on the outlet of the sludge pump, a second connecting plate disposed above the first connecting plate, the first connecting plate and the second connecting plate being connected by welding, a third connecting plate being connected to the second connecting plate by bolts, and a fourth connecting plate disposed on the outlet pipe. The second connecting plate is provided with an opening that matches the shape of the support frame, so that the second connecting plate can slide up and down along the support frame.

[0009] The inlet and outlet pipes of the mud suction pump are rigidly connected by a support frame.

[0010] The outlet coupling mechanism is a heavy-duty type.

[0011] Preferably, the inlet coupling mechanism includes an elastic connecting sleeve, one end of which is disposed on the inlet of the mud and sand pump, and the other end of which is disposed on the inlet pipe;

[0012] The surface of the elastic connecting sleeve is provided with a pipe clamp, one end of which is located at the upper part of the elastic connecting sleeve and the other end of which is located at the lower part of the elastic connecting sleeve.

[0013] Preferably, the inlet coupling mechanism includes a suction port component installed on the inlet of the sludge pump, a spring is installed on the outside of the suction port component, a nylon sleeve is installed on the inlet pipe, and a second sealing ring is installed between the suction port component and the nylon sleeve.

[0014] Preferably, the elastic connecting sleeve is a polyurethane sleeve, and the pipe clamp is a stainless steel pipe clamp.

[0015] Preferably, the elastic connecting sleeve includes a straight segment and an arc segment, the straight segment being connected to the water inlet pipe and the arc segment being connected to the water inlet of the mud and sand pump.

[0016] Preferably, the port of the straight segment is smaller than the port of the circular arc segment.

[0017] Preferably, the arc segment protrudes outward.

[0018] Compared with the prior art, the dual-coupling mud suction sand machine provided by this utility model has the following beneficial effects:

[0019] When the inlet pipe is buried and blocked by sediment, it is rigidly connected to the support frame, and the force is transmitted to the support frame without affecting the sludge pump. The outlet uses a weighted hanging plate to press and couple the sludge pump with its own weight, and the inlet uses a sliding sealing ring or spring pressing and coupling seal, which can effectively prevent the pump body from shifting under force and affecting the water output, making the operation more reliable. At the same time, the sludge pump can be maintained without stopping the water supply, which greatly saves maintenance time. Attached Figure Description

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0025] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] This utility model embodiment provides a dual-coupling mud and sand suction machine, such as Figures 1 to 3 As shown, it includes: a sludge suction pump 10, an inlet coupling mechanism 100 is provided between the inlet 11 and the inlet pipe 12 of the sludge suction pump 10, and an outlet coupling mechanism 200 is provided between the outlet 13 and the outlet pipe 14 of the sludge suction pump 10; the outlet coupling mechanism 200 includes a first connecting plate 201 provided on the outlet 13 of the sludge suction pump 10, a second connecting plate 205 provided above the first connecting plate 201, and the first connecting plate 201 and the second connecting plate 205 are connected by welding. Next, a third connecting plate 207 is bolted to the second connecting plate 205, and a fourth connecting plate 202 is installed on the outlet pipe 14. A sealing ring 204 is provided between the first connecting plate 201 and the fourth connecting plate 202. The second connecting plate 205 has an opening that matches the shape of the support frame 206, allowing the second connecting plate 205 to slide up and down along the support frame 206. The second connecting plate holds the support frame 206 and can be detached from the top of the support frame 206, which is preferably a square tube. The outlet coupling mechanism 200 is heavy-duty. After the first connecting plate 201 and the fourth connecting plate 202 slide into place along the support frame via the second connecting plate 205, they are connected together by the weight of the sludge pump. The outlet 13 of the sludge pump 10 is connected to the first connecting plate 201 by bolts 203.

[0027] When the inlet pipe is buried and blocked by sediment, it is rigidly connected to the support frame, and the force is transmitted to the support frame, which has no effect on the sludge pump. The outlet uses a weighted hanging plate to press and couple the seal with its own weight, and the inlet uses a sliding sealing ring or spring pressing and coupling seal, which can effectively prevent the pump body from shifting under force and affecting the water output.

[0028] This application designs an inlet coupling mechanism 100 and an outlet coupling mechanism 200. The sludge suction inlet 11 and outlet 13 are rigidly connected. The frictional force of the sediment on the inlet pipe 12 and outlet pipe 14 is not applied to the pump body, which effectively avoids the pump body's force displacement affecting the water output, making the operation more reliable. Furthermore, it allows the sludge suction pump to be removed for maintenance without interrupting water supply or emptying the system, greatly saving maintenance time.

[0029] In specific implementation, this application provides an inlet coupling method, specifically, the inlet coupling mechanism 100 includes an elastic connecting sleeve 101, one end of the elastic connecting sleeve 101 is disposed on the inlet 11 of the sludge pump 10, and the other end of the elastic connecting sleeve 101 is disposed on the inlet pipe 12; a pipe clamp 102 is disposed on the surface of the elastic connecting sleeve 101, one end of the pipe clamp 102 is located at the upper part of the elastic connecting sleeve 101, and the other end of the pipe clamp 102 is located at the lower part of the elastic connecting sleeve 101.

[0030] Due to its own weight, the sludge suction pump 10 will press down, sealing the inlet 11 with the inlet pipe. Therefore, the flexible connecting sleeve 101 needs to have a certain degree of elasticity.

[0031] In a specific implementation, this application provides another inlet coupling method, specifically, the inlet coupling mechanism 100 includes a suction member 103 disposed on the inlet 11 of the mud and sand pump 10, a spring 104 disposed on the outside of the suction member 103, a nylon sleeve 105 disposed on the inlet pipe 12, and a second sealing ring 106 disposed between the suction member 103 and the nylon sleeve 105.

[0032] In specific implementation, the elastic connecting sleeve 101 is a polyurethane sleeve, and the pipe clamp 102 is a stainless steel pipe clamp.

[0033] In specific implementation, the elastic connecting sleeve 101 includes a straight segment 111 and an arc segment 121. The straight segment 111 is connected to the water inlet pipe 12, and the arc segment 121 is connected to the water inlet 11 of the mud and sand pump 10.

[0034] In a specific implementation, the port of the straight segment 111 is smaller than the port of the arc segment 121, and the arc segment 121 protrudes outward.

[0035] In practice, the inlet pipe 12 and outlet pipe 14 of the mud suction pump are rigidly connected by a support frame 206.

[0036] In summary, this utility model discloses a dual-coupling mud and sand suction machine, comprising: a mud and sand suction pump, an inlet coupling mechanism between the inlet of the mud and sand suction pump and the inlet pipe, and an outlet coupling mechanism between the outlet of the mud and sand suction pump and the outlet pipe; the outlet coupling mechanism includes a first connecting plate disposed on the outlet of the mud and sand suction pump, a second connecting plate disposed above the first connecting plate, the first connecting plate and the second connecting plate being connected by welding, a third connecting plate being connected to the second connecting plate by bolts, and a fourth connecting plate disposed on the outlet pipe, the second connecting plate having an opening matching the shape of the support frame, allowing the second connecting plate to slide up and down along the support frame; after the first connecting plate and the fourth connecting plate slide into position along the support frame via the second connecting plate, they are connected by the weight of the mud and sand suction pump, and a sealing ring is disposed between the first connecting plate and the fourth connecting plate.

[0037] The outlet coupling mechanism is of a heavy-duty type, which can effectively prevent the pump body from shifting under stress and affecting the water output, making the operation more reliable. At the same time, the mud and sand pump can be maintained without stopping the water supply, which greatly saves maintenance time.

[0038] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application. This application can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this application.
