Description

Technical Field

[0001] The utility model relates to the field of sewage pipeline equipment, in particular to a pump siphon pipeline system for a sludge suction machine. Background Art

[0002] At present, many environmental protection treatment facilities need to be equipped with mud discharge equipment. Patent announcement document CN221535719U discloses a mud discharge equipment using a direct suction pump. This direct suction mud discharge equipment can use the power of the pump to continuously extract mud and water. Although this method of directly extracting mud and water using a pump can directly and effectively extract mud and water, the flowing mud and water itself has a certain kinetic energy, so the direct suction mode of the pump cannot fully utilize the kinetic energy of the mud and water itself. Therefore, the energy consumption of this mud discharge equipment during use is relatively high. Utility Model Content

[0003] In response to the above-mentioned problems, the present utility model proposes a pump siphon pipeline system for a mud suction machine. This system utilizes the characteristic that the flowing mud and water have a certain kinetic energy, so that after the initial extraction is completed, the kinetic energy of the mud and water is used to realize siphon mud discharge. Compared with the mud discharge mode using direct suction by a pump, the energy consumption of this system during mud discharge is relatively low.

[0004] The technical solutions adopted by this utility model are as follows:

[0005] A pump siphon pipeline system for a sludge suction machine includes a feed pipe, a mud discharge pipe, a suspended check valve, a gravity check valve, a siphon main pipe, a bypass pipe, a submersible sewage pump, a bypass pipe and an auxiliary pipe. The siphon main pipe and the feed pipe are respectively connected to the two ends of the suspended check valve, the bypass pipe is connected to the feed pipe, the two ends of the submersible sewage pump are respectively connected to the bypass pipe and the auxiliary pipe, the two ends of the gravity check valve are respectively connected to the auxiliary pipe and the bypass pipe, the bypass pipe and the siphon main pipe are both connected to the mud discharge pipe, and the feed pipe, siphon main pipe and mud discharge pipe are located in a straight line.

[0006] The working process of this piping system is as follows: first, in the shutdown state, the suspended check valve and the gravity check valve are both in the closed state.

[0007] In suction mode, the submersible sewage pump starts pumping muddy water. The submersible sewage pump draws sewage from the feed pipe into the bypass pipe, then into the submersible sewage pump through the bypass pipe and then into the auxiliary pipe. Under the pumping of the submersible sewage pump, the muddy water pushes open the gravity check valve and enters the bypass pipe, and finally into the mud discharge pipe. When the muddy water enters the mud discharge pipe, some of it will flow into the siphon main pipe. This part of the muddy water in the siphon main pipe will press down and block the suspended check valve, so that the muddy water can only enter the mud discharge pipe through the bypass pipe, submersible sewage pump, auxiliary pipe, gravity check valve and bypass pipe. When the pump stops operating, the muddy water in the feed pipe no longer enters the bypass pipe but flows to the suspended check valve, thereby directly pushing open the suspended check valve and entering the siphon main pipe (similarly, the muddy water flowing out of the mud discharge pipe will also suck out the muddy water in the siphon main pipe, thereby forming negative pressure, making it easier for the muddy water in the feed pipe to push open the suspended check valve). After entering the siphon main pipe, the muddy water finally enters the mud discharge pipe. This is the siphon mode.

[0008] In summary, this type of piping system can switch between pumping and siphoning modes simply by controlling the switch of the submersible sewage pump. The switching process is convenient and fast, and can reduce energy consumption during sludge discharge.

[0009] Optionally, a discharge pipe is further included, which is connected to the mud discharge pipe, and a vacuum breaking component is provided on the mud discharge pipe or the discharge pipe.

[0010] The muddy water that enters the mud discharge pipe will eventually be discharged into the discharge pipe. The vacuum breaker component is in the closed state in both pump suction and siphon modes, and is only in the open state when the system is in the shutdown state.

[0011] Optionally, a mud suction nozzle is further included, and the mud suction nozzle is arranged at the pipe mouth of the feeding pipe.

[0012] Optionally, the mud suction nozzle is a trumpet-shaped mud suction nozzle.

[0013] The purpose of setting the trumpet-shaped mud suction nozzle is to ensure that mud and water can enter the feed pipe stably.

[0014] Optionally, the suspended check valve includes a shell, a prismatic float and a guide ring, the guide ring is arranged in the shell, the prismatic float is arranged in the shell, and guide rods are provided at both ends of the prismatic float, and the guide rods at both ends are slidably fitted with the guide ring.

[0015] Optionally, a fixing rod is further included, wherein the fixing rod is arranged in the shell, and the guide ring is arranged on the fixing rod.

[0016] Optionally, a counterweight is provided on the guide rod.

[0017] Optionally, a peripheral limit block is provided in the shell.

[0018] The beneficial effect of the utility model is that the pumping mode and the siphoning mode can be switched only by controlling the switch of the submersible sewage pump, the switching process is convenient and fast, and the energy consumption during mud discharge can be reduced.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] In the description of this application, it should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn according to the actual proportional relationship. Technologies, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but where appropriate, the technologies, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0031] As attached Figure 1 、 2 As shown in Figure 3, a pump siphon piping system for a sludge suction machine includes a feed pipe 2, a mud discharge pipe 9, a suspended check valve 7, a gravity check valve 6, a siphon main pipe 8, a bypass pipe 61, a submersible sewage pump 4, a bypass pipe 3 and an auxiliary pipe 5. The siphon main pipe and the feed pipe 2 are respectively connected to the two ends of the suspended check valve 7, the bypass pipe 3 is connected to the feed pipe 2, the two ends of the submersible sewage pump 4 are respectively connected to the bypass pipe 3 and the auxiliary pipe 5, the two ends of the gravity check valve 6 are respectively connected to the auxiliary pipe 5 and the bypass pipe 61, the bypass pipe 61 and the siphon main pipe 8 are both connected to the mud discharge pipe 9, and the feed pipe 2, the siphon main pipe 8 and the mud discharge pipe 9 are located in a straight line.

[0032] The working process of this pipeline system is as follows: first, in the shutdown state, the suspended check valve 7 and the gravity check valve are both in the closed state.

[0033] In the pumping mode, the submersible sewage pump 4 is turned on to pump mud and water. The submersible sewage pump 4 draws sewage from the feed pipe 2 into the bypass pipe, enters the submersible sewage pump 4 through the bypass pipe 3, and then enters the auxiliary pipe 5. Under the pumping of the submersible sewage pump 4, the mud and water push open the gravity check valve 6 and enter the bypass pipe 61, and finally enter the mud discharge pipe 9. When the mud and water enter the mud discharge pipe 9, part of the mud and water will flow into the siphon main pipe 8. This part of the mud and water in the siphon main pipe 8 will press down to block the suspended check valve 7, so that the mud and water can only enter the mud discharge pipe 9 through the bypass pipe, the submersible sewage pump 4, the auxiliary pipe 5, the gravity check valve 6 and the bypass pipe 61 (this state is as shown in the attached figure). Figure 2When the pump stops working, the muddy water in the feed pipe 2 no longer enters the bypass pipe but flows to the floating check valve 7, thereby directly pushing open the floating check valve 7 and entering the siphon main pipe 8 (similarly, the muddy water flowing out of the mud discharge pipe 9 will also suck out the muddy water in the siphon main pipe 8, thereby forming a negative pressure, making it easier for the muddy water in the feed pipe 2 to push open the floating check valve 7). After entering the siphon main pipe 8, the muddy water finally enters the mud discharge pipe 9. This is the siphon mode (this state is as shown in the attached figure). Figure 3 (as shown in

[0034] Attachment Figure 2 With attached Figure 3 When the entire system is working, the suspended check valve 7, gravity check valve, siphon main pipe 8, submersible sewage pump 4, bypass pipe, feed pipe 2, auxiliary pipe 5 and bypass pipe 61 are all located below the liquid surface.

[0035] In summary, this piping system can switch between the pumping mode and the siphoning mode simply by controlling the switch of the submersible sewage pump 4. The switching process is convenient and fast, and the energy consumption during sludge discharge can be reduced.

[0036] As attached Figure 1 、 2 As shown in FIG3 , the apparatus further includes a discharge pipe 11 , which is connected to the mud discharge pipe 9 , and a vacuum breaking assembly 10 is provided on the mud discharge pipe 9 or the discharge pipe 11 .

[0037] The muddy water entering the mud discharge pipe 9 will eventually be discharged into the discharge pipe 11. Specifically, the vacuum breaking component 10 is in a closed state in both pump suction and siphon modes, and is only in an open state when the system is in a shutdown state.

[0038] As attached Figure 1 、 2 As shown in 3 , it also includes a mud suction nozzle 1 , which is arranged at the mouth of the feed pipe 2 .

[0039] As attached Figure 1 、 2 As shown in FIG3 , the mud suction nozzle 1 is a trumpet-shaped mud suction nozzle 1 .

[0040] The purpose of providing the trumpet-shaped mud suction nozzle 1 is to ensure that muddy water can stably enter the feed pipe 2 .

[0041] As attached Figures 4-7 As shown, the suspended check valve 7 includes a shell 701, a prismatic float 702 and a guide ring 704. The guide ring 704 is arranged in the shell 701, and the prismatic float 702 is arranged in the shell 701. Guide rods 705 are provided at both ends of the prismatic float 702. The guide rods 705 at both ends are slidably fitted with the guide ring 704.

[0042] The opening at the lower end of the shell 701 is used to connect with the feed pipe 2, and the opening at the upper end of the shell is used to connect with the siphon main pipe 8. The muddy water in the feed pipe 2 flows upward, and the prismatic float 702 moves upward. When muddy water in the siphon main pipe 8 moves downward, the prismatic float moves downward and blocks the opening at the lower end.

[0043] The guide rod 705 is slidably engaged with the guide ring 704 , thereby guiding the up and down movement of the prismatic float 702 .

[0044] As attached Figures 4-7 As shown, a fixing rod is further included. The fixing rod is arranged in the housing 701, and the guide ring 704 is arranged on the fixing rod.

[0045] As attached Figures 4-7 As shown, a counterweight block 706 is provided on the guide rod 705 .

[0046] The functions of the counterweight block 706 are, firstly, to provide a counterweight and, secondly, to make the prism more stable when floating up and down.

[0047] As attached Figures 4-7 As shown, a peripheral limiting block 707 is provided in the housing 701 .

[0048] The function of the peripheral limiting block 707 is to limit the prismatic float 702 to a certain extent, so as to prevent the prismatic float 702 from moving upward and blocking the opening at the upper end of the shell 701.

[0049] As attached Figures 4-7 As shown, a concave water drain trough 7021 is provided on the prismatic float 702 .

[0050] The function of the concave drain tank 7021 is to allow the water level in the pipe above the prismatic float to slowly drop after shutdown.

[0051] The above-described embodiments only express some embodiments of the present invention. The description is relatively specific and detailed, but it should not be understood as limiting the scope of the patent of the present invention. It should be pointed out that for those skilled in the art, it is still possible to modify the technical solutions described in the above-mentioned embodiments or to replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this utility model should be included in the scope of protection of this utility model.
