Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.

As shown in fig. 1 and 2, the utility model provides a filter slag discharging equipment for rain sewage self-suction pump station, which comprises a vertical sealed box body, wherein the sealed box body is provided with a water inlet 1, a water outlet 6 and a sewage outlet 10.

In this embodiment, the bottom of the sealed box body is a support section for supporting the sealed box body at the upper part of the sealed box body. The water inlet 1 is arranged at the upper end of the sealed box body, the sewage draining outlet 10 is arranged at the lower end of the sealed box body, the water inlet 1 is communicated with the sewage draining outlet 10, and the detachable tubular filter 3 is arranged between the water inlet 1 and the sewage draining outlet 10.

In this embodiment, the tubular filter 3 is made of stainless steel, the tubular body of the tubular filter 3 is provided with meshes as filtering holes, and the meshes have a smaller size so as to filter out the small-sized impurity slag, but the water flux is also reduced, so the size of the meshes is usually determined according to the size of the impurity slag in the local water collecting well and the self-filtering capability of the self-priming pump set. In other embodiments, a tube filter 3 with similar effect, such as a tube membrane filter, a tube screen, etc., may be used.

In this embodiment, the drain outlet 10 and the connection section between the tubular filter 3 is in slope transition or arc transition, so that the filtered impurity slag can automatically slide to the drain outlet 10 under the influence of gravity, and is beneficial to cleaning after long-term use.

In this embodiment, drain 10 links to each other with the sediment pond of locating ground pump station, also can shift miscellaneous sediment to other temporary storage departments through the blow off pipe and wait for the clearance in other embodiments, is favorable to reducing the clearance number of times, practices thrift the cost.

In this embodiment, the sewage outlet 10 is provided with an electrically controlled slag discharge valve 4, and the opening and closing can be set by the PLC according to the blocking condition judged by the flow sensor in the device. Since the water level in the sealed tank is lowered when the sewage draining outlet 10 is started, the frequency of automatically draining the impurity slag needs to be reduced, and the water level in the sealed tank is ensured to be maintained at a high level for a long time.

In this embodiment, the support section is the tank support body 8 that the stainless steel square pipe is constituteed, pass through bolt fixed connection between tank support body 8 and the sealed box. The sealed box body is convenient to disassemble and clean, and the sealed box body is simple in structure and convenient to maintain.

In this embodiment, the outer surface of the sealed box body is provided with a flange pipe and a blind plate 7, and the tubular filter 3 is sleeved in the flange pipe. When the tubular filter 3 needs to be detached independently, the tubular filter 3 can be directly taken out from the sealed box body only by detaching the blind plate 7 and disconnecting the water inlet 1 and the sewage outlet 10, so that the blocked sundry residues can be conveniently cleaned.

The inside of the tubular filter 3 is an inner tubular section 9, and the inside of the sealed box body and the outside of the tubular filter 3 are outer tubular sections 2. In one embodiment, as shown in FIG. 1, the water outlet 6 is connected to the tube exterior section 2 of the tube filter 3 when the water inlet 1 is connected to the tube interior section 9 of the tube filter 3. At this time, the rain sewage and the trash entering from the water inlet 1 can flow through the pipe inner section 9 of the pipe filter 3 and reach the sewage outlet 10. Because the sewage discharge port 10 is normally closed, the water surface of the rainwater and sewage continuously rises until the height reaches the pipe wall of the tubular filter 3, and the rainwater and sewage are discharged to the outer section 2 of the tubular filter 3 through the meshes and are pumped out by the self-suction pump group through the water outlet 6; the slag is accumulated at the sewage outlet 10 and is discharged periodically through the electric control slag discharging valve 4.

In another embodiment, as shown in FIG. 2, when the water inlet 1 is connected to the exterior section 2 of the candle filter 3, the water outlet 6 is connected to the interior section 9 of the candle filter 3. At this time, the trash and most of the rain water entering from the water inlet 1 bypass the tube filter 3 and reach the sewage outlet 10 from the outer tube section 2 of the tube filter 3. Because the sewage discharge port 10 is normally closed, the water surface of the rainwater and sewage continuously rises until the height reaches the pipe wall of the tubular filter 3, then the rainwater and sewage enters the pipe inner section 9 of the tubular filter 3 through the meshes and is pumped out by the self-priming pump group through the water outlet 6; the miscellaneous slag is accumulated at the sewage outlet 10 and is discharged periodically through the electric control slag discharging valve 4.

In addition, the top end of the pipe outer section 2 is provided with an exhaust pipe 5 communicated with the outside. The exhaust pipe 5 is normally closed, and the opening of the water level control in the sealed box body is confirmed through a sensor. The exhaust pipe 5 is used for exhausting gas sucked by the self-priming pump set in the sealed box body, so that rainwater and sewage in the filtering and deslagging equipment can be kept at a high position when the self-priming pump set sucks the rainwater and the sealed box body is prevented from being difficult to suck and water cut-off due to excessive gas and excessive pressure.
