The utility model proposes a kind of slag cleaning devices, as shown in Figure 1, include cylinder, be provided on cylinder wastewater inlet 2, Backwash mouth 4, outlet of sewer 3 and the drainage wash mouth 8 positioned at cylinder body bottom, the bore of drainage wash mouth 8 be less than sewage into Mouth 2, backwash mouth 4, the respective bore of outlet of sewer 3, the inside of cylinder, which is equipped with, separates the cylinder into the first reservoir chamber 6 and second The filtration members 5 of reservoir chamber 7, backwash mouth 4 and drainage wash mouth 8 is located at cylinder and is formed on the barrel wall of the first reservoir chamber 6, sewage Import 2 and outlet of sewer 3 are located at cylinder and are formed on the barrel wall of the second reservoir chamber 7.

Above-mentioned slag cleaning device is arranged in basement sewage lifting system, for can be blocked in filter sewage elevator pump compared with Thick sundries.Sewage passes through wastewater inlet 2 first and enters the second reservoir chamber 7, and then by filtration members 5, sundries is intercepted at second Reservoir chamber 7, filtered sewage enter the first reservoir chamber 6, and then extra sewage is flowed out from drainage wash mouth 8, flow to sewage In the header tank of lifting system.

Wherein, if slag cleaning device is located in header tank, drainage wash mouth 8 may be configured as drainage wash hole；If scarfing cinder Device is located at outside header tank, is located at a settable water pipe at drainage wash mouth 8 in cylinder, sewage is drained into header tank. The diameter dimension of drainage wash mouth 8 can be designed according to concrete technology, need to guarantee there is certain flow when sewage enters, not all right cecutiency End, enters in slag cleaning device convenient for the sewage containing sundries, while need to guarantee that water yield cannot when sewage pump is opened again It is too big, it otherwise will affect flushing of the back-flushing to sundries.In addition, the water flow that ejects of over flow rinse mouth can be into header tank bottom Row rinses, convenient for the cleaning of header tank deposit.

After the liquid level of header tank reaches preset value, sewage lifting pump startup, the sewage in header tank enters recoil water pipe (being located between sewage pump and backwash mouth 4), back-flushing enters the second reservoir chamber 7, and sundries is washed away from outlet of sewer 3. Meanwhile the water flow ejected from drainage wash mouth 8, header tank bottom is stirred, makes in header tank deposit simultaneously by sewage lifting Pumping is walked, and outlet of sewer 3 is then discharged out.

Further, in this embodiment cylinder be cylinder, keep drainage flow more smooth.Further, above-mentioned cylinder For stainless steel cylinder, the corrosion resistance of the utility model slag cleaning device is increased.

Specifically, filtration members 5 are filtering sieve plate, and the plate face for filtering sieve plate is located at cylinder in the radial direction, filter sieve plate On be covered with filter hole, the diameter dimension of filter hole can need to design according to concrete technology.

In addition, as shown in Figure 1, cylinder is including the first end wall 11, the second end wall 12 and is connected to the first end wall 11 and second Circumferential wall 13 between end wall 12, backwash mouth 4 are located at the first end wall 11.Wastewater inlet 2 is located in circumferential wall 13, outlet of sewer 3 are located on the second end wall 12.Backwash mouth 4 and outlet of sewer 3 are located on the axis of cylinder or are parallel to the same line of axis On.The slag cleaning device of the utility model is designed as three way type structure, simple and compact for structure, and convenient for sewage flowing and sundries from Outlet of sewer 3 is discharged.

Slag cleaning device in the present embodiment is located at wastewater inlet 2, outlet of sewer 3 and backwash mouth 4 in cylinder to be set respectively Sewage inlet pipe, sewage outlet pipe and backwash tube are set, wherein sewage inlet pipe, sewage outlet pipe and backwash tube can pass through flanged joint It is easy to disassemble to cylinder, it is also solderable to be connected to cylinder, increase stability.

The utility model additionally provides a kind of sewage lifting system, including water inlet pipe, outlet pipe, recoil water pipe, sewage mention Rise pump and above-mentioned slag cleaning device, wastewater inlet 2 and outlet of sewer 3 are respectively communicated with water inlet pipe and outlet pipe, sewage pump and anti- Rinse mouth 4 passes through recoil water pipe connection.The specific structure of the slag cleaning device is referring to above-described embodiment, due to the sewage lifting system Using whole technical solutions of above-mentioned all embodiments, therefore at least institute brought by the technical solution with above-described embodiment There is beneficial effect, this is no longer going to repeat them.

The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model, It is all under the design of the utility model, equivalent structure transformation made based on the specification and figures of the utility model, or Directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
