Description

Technical Field

[0001] This utility model relates to the field of prefabricated pumping station technology, and in particular to a pre-crushing device for an integrated prefabricated pumping station. Background Technology

[0002] Integrated prefabricated pumping stations can transport urban domestic sewage to sewage treatment plants located on the outskirts of the city for treatment. The pre-crushing device is an important component of the prefabricated pumping station. Its function is to pre-crush or break up the solid waste in the domestic sewage before it is pumped to the sewage treatment plant, so as to avoid blockage during subsequent transportation.

[0003] For example, the pre-crushing device of the integrated prefabricated pumping station disclosed in the utility model patent with authorization announcement number CN222789334U can block the splashed solid waste when crushing garbage. However, it is only suitable for the direct treatment of solid waste. Therefore, in actual use, it is necessary to use a special filtration device to filter out the solid waste in the domestic sewage, and then transfer the filtered solid waste from the filtration device to the above-mentioned crushing device. In actual use, it is too inconvenient and the treatment efficiency is not ideal.

[0004] Therefore, it is necessary to invent a pre-crushing device for an integrated prefabricated pumping station to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a pre-crushing device for an integrated prefabricated pumping station, which can directly treat domestic sewage containing solid waste. After collecting the solid waste, it can be transported directly by gravity, making it more convenient in actual use and improving the treatment efficiency of solid waste. This solves the problem that the existing solutions mentioned in the background art are only suitable for the direct treatment of solid waste. Therefore, in actual use, it is necessary to use a special filtration device to filter out the solid waste in the domestic sewage, and then transfer the filtered solid waste from the filtration device to the crushing device. This is too inconvenient in actual use and the treatment efficiency is not ideal.

[0006] According to one aspect of this disclosure, the following technical solution is provided: a pre-crushing device for an integrated prefabricated pumping station, comprising:

[0007] A crushing assembly for crushing falling solid waste;

[0008] Wastewater transfer mechanism, wherein the wastewater transfer mechanism is used to transfer domestic wastewater; and

[0009] The collection and falling mechanism includes an overflow baffle fixedly installed in the middle of the inner side of the collection box. A barrier net is fixedly installed between the top left side of the overflow baffle and the inner wall of the collection box. The collection and falling mechanism also includes a collection hopper fixedly nested in the bottom left side of the collection box. The collection hopper is fixedly installed through the top of the crushing box. A sealing channel is provided through the bottom front of the collection hopper. A sealing ring is fixedly nested in the inner side of the sealing channel and an L-shaped baffle is slidably inserted. An electric push rod is fixedly connected between the L-shaped baffle and the collection hopper. Two guide shafts parallel to the electric push rod are slidably installed through the front of the L-shaped baffle. Both guide shafts are fixedly installed in the top front of the collection hopper.

[0010] According to at least one embodiment of the present disclosure, the pre-crushing device for an integrated prefabricated pump station includes a crushing box, a support base A fixedly disposed at the bottom of the crushing box, and a guide mesh plate fixedly disposed at the bottom inner side of the crushing box.

[0011] According to at least one embodiment of the pre-crushing device of the integrated prefabricated pumping station of the present disclosure, two parallel crushing rollers are rotatably nested inside the crushing box via bearings, and two motors are fixedly installed on the front of the crushing box. The two motors are respectively connected to the two crushing rollers and drive the two crushing rollers to rotate relative to each other.

[0012] According to at least one embodiment of the present disclosure, the pre-grinding device of an integrated prefabricated pumping station includes a collection box fixedly disposed on the top of the grinding box, and a support base B fixedly disposed on the bottom of the collection box.

[0013] According to at least one embodiment of the pre-crushing device of the integrated prefabricated pumping station of the present disclosure, a sewage input pipe is fixedly installed through the left side of the collection box, and a sewage output pipe is fixedly installed through the right side of the collection box.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This invention features a collection and descent mechanism. When domestic sewage enters the collection tank through the sewage inlet pipe, a barrier net filters out solid waste from the sewage, storing it on the left side of the collection tank's inner cavity and inside the collection hopper. The filtered sewage then flows over the overflow baffle and into the right side of the collection tank's inner cavity, before exiting through the sewage outlet pipe. Once sufficient solid waste has been stored, the sewage inlet pipe is stopped, and an electric push rod drives an L-shaped baffle, guided by a guide shaft, to move forward. This releases the L-shaped baffle from blocking the discharge port at the bottom of the collection hopper. At this point, the solid waste on the left side of the collection tank's inner cavity and inside the collection hopper falls under gravity and is crushed inside the crushing assembly. Compared to existing technologies, this invention can directly treat domestic sewage containing solid waste. Furthermore, after collecting the solid waste, gravity can be used to transport it, making it more convenient in practical use and improving the efficiency of solid waste treatment.

[0026] Figure 2 This is a schematic diagram of the crushing component 1 of the pre-crushing device of an integrated prefabricated pumping station according to one embodiment of the present disclosure.

[0027] Figure 3 This is a schematic diagram of the sewage transmission mechanism 2 and the collection and falling mechanism 3 of the pre-crushing device of an integrated prefabricated pumping station according to one embodiment of the present disclosure.

[0028] like Figures 1-3 As shown, the pre-grinding device of the integrated prefabricated pumping station disclosed herein may include: a grinding component 1, a sewage transmission mechanism 2, and a collection and falling mechanism 3, etc. The three work together to realize an integrated process of "sewage filtration - solid collection - gravity conveying - grinding treatment", and the overall structure is as follows. Figure 1 As shown, the components are compactly arranged, making them suitable for installation in small spaces in prefabricated pumping stations.

[0029] like Figure 2As shown in this disclosure, the crushing assembly 1 includes a crushing box 11, which is welded from 304 stainless steel and has corrosion resistance and impact resistance. A support base A12 is fixedly installed at the bottom of the crushing box 11. The support base A12 is fixed to the ground by expansion bolts to prevent the crushing box 11 from shifting due to vibration. A guide mesh plate 13 is fixedly installed on the bottom inner side of the crushing box 11. It is made of wear-resistant cast iron to extend its service life. Two parallel crushing rollers 14 are nested inside the crushing box 11 through bearings. Both crushing rollers 14 are made of high chromium alloy and have interlaced serrated protrusions on their surfaces. Two motors 15 are fixedly installed on the front of the crushing box 11. The two motors 15 are respectively connected to the two crushing rollers 14 and drive the two crushing rollers 14 to rotate relative to each other. The motors 15 are servo motors with a power of 1.5kW. They are connected to the crushing rollers 14 through a coupling and have overload protection function (automatic shutdown when the load exceeds 1.2 times the rated value) and support forward and reverse rotation control (for easy removal of stuck solids).

[0030] Therefore, when solid waste falls between the two crushing rollers 14 under the action of gravity, it is continuously crushed by the two crushing rollers 14 because the two motors 15 drive the two crushing rollers 14 to rotate relative to each other. The crushed solid waste falls to the top of the guide plate 13 under the action of gravity and is guided out by the guide plate 13.

[0031] It should also be noted that the bottom of the inner cavity of the pulverizing box 11 is provided with an inclined guide surface that is lower on the left and higher on the right. At the same time, a return pipe (not shown) is fixedly installed through the bottom of the left end of the pulverizing box 11 so that a small amount of domestic sewage that falls synchronously with the solid debris can approach the return pipe under the action of the inclined guide surface after passing through the guide plate 13 and be output by the return pipe.

[0032] like Figure 3 As shown, in a preferred embodiment, the sewage transfer mechanism 2 includes a collection box 21 fixedly mounted on the top of the pulverizing box 11. A support base B22 is fixedly mounted on the bottom of the collection box 21. A sewage inlet pipe 23 is fixedly installed through the left side of the collection box 21, and a sewage outlet pipe 24 is fixedly installed through the right side of the collection box 21. Both the sewage inlet pipe 23 and the sewage outlet pipe 24 are DN100 HDPE pipes. An electromagnetic flow valve (range 0-50m) is equipped on the sewage inlet pipe 23. 3 The system can monitor the sewage input in real time ( / h), and the sewage output pipe 24 is connected to the main pipeline of the pump station to transport the filtered sewage to the subsequent treatment stage.

[0033] Therefore, when domestic sewage enters the collection tank 21 through the sewage inlet pipe 23, the barrier net 32 ​​filters the solid waste in the domestic sewage. The filtered domestic sewage passes over the overflow baffle 31 and enters the right side of the inner cavity of the collection tank 21, and then flows out through the sewage outlet pipe 24.

[0034] like Figure 3 As shown in this disclosure, the collection and falling mechanism 3 includes an overflow baffle 31 fixedly installed in the middle of the inner side of the collection box 21. A barrier net 32 ​​is fixedly installed between the top left side of the overflow baffle 31 and the inner wall of the collection box 21. The collection and falling mechanism 3 also includes a collection hopper 33 fixedly nested in the bottom left side of the collection box 21. The collection hopper 33 is fixedly installed through the top of the crushing box 11. A sealing channel 34 is installed through the bottom front of the collection hopper 33. A sealing ring is fixedly nested in the inner side of the sealing channel 34 and an L-shaped baffle 35 is slidably inserted. The sealing ring can seal the gap between the inner wall of the sealing channel 34 and the L-shaped baffle 35, thereby preventing domestic sewage from flowing into the working environment through the sealing channel 34. An electric push rod 36 is fixedly connected between the L-shaped baffle 35 and the collection hopper 33. Two guide shafts 37 parallel to the electric push rod 36 are slidably installed through the front of the L-shaped baffle 35. Both guide shafts 37 are fixedly installed in the top front of the collection hopper 33.

[0035] Therefore, the barrier net 32 ​​can filter the solid waste in the domestic sewage inside the collection box 21 and store it in the left side of the inner cavity of the collection box 21 and inside the collection hopper 33. When enough solid waste is stored, the sewage input pipe 23 is stopped, and then the electric push rod 36 drives the L-shaped baffle 35, which is guided by the guide shaft 37, to move forward continuously. This causes the L-shaped baffle 35 to release the blockage of the bottom discharge port of the collection hopper 33. At this time, the solid waste in the left side of the inner cavity of the collection box 21 and inside the collection hopper 33 continues to fall into the crushing component 1 under the action of gravity and is crushed. Compared with the prior art, domestic sewage containing solid waste can be directly treated. At the same time, after the solid waste is collected, gravity can be used to transport the solid waste, which is more convenient in actual use and improves the treatment efficiency of solid waste.

[0036] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0037] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
