Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment device. Background Art

[0002] Domestic sewage and municipal wastewater mostly share the same drainage system. Sewage is often mixed with a variety of household waste. During the initial stages of sewage treatment, it's necessary to filter out the relatively large, low-density waste to prevent it from entering the subsequent treatment process and causing serious blockage or damage to subsequent sewage treatment equipment.

[0003] Since the initial sewage is mixed with various plastic bags, packaging bags and other soft garbage, this type of garbage will easily get entangled on the filter fence under the impact of the water flow during the initial filtration of the sewage, making it difficult to fall off and requiring manual assistance in cleaning. Existing patent application No. 202420002581.1 discloses a sewage treatment device, which arranges a water filter conveyor belt below the outlet of the sewage pipe to facilitate the transverse transportation of the intercepted garbage to the top of the collection frame located on the side. Through the action of gravity, the garbage naturally falls into the collection frame, thereby enhancing the working performance of the sewage treatment device. However, since the main part of the water filter conveyor belt is a filter interception surface formed by a number of equally spaced horizontal railings, the above-mentioned technical problems still exist when intercepting flexible garbage such as plastic bags and packaging bags carried by sewage. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a sewage treatment device to solve the problem that flexible garbage such as plastic bags and packaging bags in sewage are easily entangled, difficult to fall off, and difficult to self-clean.

[0005] Based on the above purpose, the utility model provides a sewage treatment device, including a primary filter box and an external support frame fixed to the top of the primary filter box, a sewage pipe is provided on the external support frame, and the bottom of the primary filter box is connected to a drain pipe. The sewage treatment device also includes:

[0006] Garbage dumping chutes are provided on both sides of the primary filter box.

[0007] A plurality of horizontal bars are fixed in parallel in the primary filter box, and a water flow groove is formed between two adjacent horizontal bars.

[0008] A cleaning portion is provided in the primary filter box, and is used for cleaning garbage that has fallen on the horizontal bars and is stuck in the water ditch.

[0009] A collection box is arranged outside the garbage dump chute.

[0010] Preferably, the cleaning unit comprises:

[0011] A supporting horizontal bar is transversely arranged on the top of the horizontal bar, and a plurality of transverse grooves are transversely arranged in parallel at the bottom of the supporting horizontal bar, and comb teeth are formed between two adjacent transverse grooves.

[0012] Connecting rods are fixed to both ends of the supporting horizontal bar.

[0013] Two nut seats are relatively slidably arranged at the top boundary of the primary filter box, and the bottoms of the nut seats are fixedly arranged on the top of the connecting rod.

[0014] A driving member is used to drive the two nut seats to move linearly in the same direction synchronously.

[0015] Preferably, the cross-bar passes through the cross-slot transversely, and the cross-section of the cross-bar matches the cross-section of the cross-slot.

[0016] Preferably, the comb teeth are slidably sleeved in the water-passing groove, and the tops of the comb teeth are inclined surfaces.

[0017] Preferably, both sides of the exterior of the supporting horizontal bar are inclined surfaces, and the supporting horizontal bar is slidably arranged in the primary filter box.

[0018] Preferably, the outer support frame is located on the top of the primary filter box, and the outer support frame spans both sides of the exterior of the primary filter box.

[0019] Preferably, the sewage treatment device also includes a medicine dosing box fixed on the outer support frame and a sealing plate that is laterally rotatable and arranged at the bottom of the medicine dosing box. The sealing plate is used to seal the medicine outlet at the bottom of the medicine dosing box, and an extension rod is fixed on the sealing plate.

[0020] Preferably, the length of the extension rod is greater than the distance between the connecting rod close to the medicine adding box and the sealing plate.

[0021] The beneficial effects of the present invention are as follows: the present invention supports horizontal bars and comb teeth that move back and forth in a horizontal straight line and designs both sides of the two as inclined surfaces, so that the garbage falling on the horizontal bars can be pushed into the collection boxes on both sides of the outside of the primary filter box, and the flexible garbage such as plastic bags and packaging bags wrapped and hung on the horizontal bars can be pushed into the collection box at the same time, thereby improving the self-cleaning performance of the primary filter box and avoiding affecting the primary filtration effect of sewage. The garbage stuck in the water gutter can also be pushed out and pushed into the collection box to avoid the water gutter being blocked and affecting the cleaning effect of the cleaning part.

[0032] like Figures 1 to 5 As shown, a sewage treatment device includes a primary filter box 1 and an outer support frame 6 fixed to the top of the primary filter box 1, a sewage pipe 7 is provided on the outer support frame 6, and a drain pipe 8 is connected to the bottom of the primary filter box 1. The sewage treatment device also includes:

[0033] Garbage dumping chutes 2 are arranged on both sides of the primary filter box 1.

[0034] A plurality of horizontal bars 3 are fixed in parallel in the primary filter box 1 , and a water flow channel 4 is formed between two adjacent horizontal bars 3 .

[0035] The cleaning portion 5 is provided in the primary filter box 1 and is used to clean the garbage that has fallen on the horizontal bars 3 and is stuck in the water channel 4.

[0036] A collection box 9 is provided outside the garbage dump 2 .

[0037] The sewage pipe 7 discharges untreated sewage to the top of several horizontal bars 3 arranged in parallel. The filtering surface formed by several horizontal bars 3 will filter out relatively large solid waste in the sewage to avoid omissions and affect the normal operation of the equipment used for subsequent sewage treatment.

[0038] like Figures 2 to 4 As shown, the cleaning unit 5 includes:

[0039] A supporting horizontal bar 51 is transversely arranged at the top of the horizontal bar 3 , and a plurality of transverse grooves 52 are transversely arranged in parallel at the bottom of the supporting horizontal bar 51 , with comb teeth 53 formed between two adjacent transverse grooves 52 .

[0040] Connecting rods 54 are fixed to both ends of the supporting horizontal bar 51 .

[0041] Two nut seats 55 are relatively slidably arranged at the top boundary of the primary filter box 1 , and the bottom of the nut seat 55 is fixedly arranged on the top of the connecting rod 54 .

[0042] A driving member 56 is used to drive the two nut seats 55 to move synchronously in the same direction. The driving member 56 includes two reciprocating screws that are arranged on the top of the primary filter box 1 and rotate relative to each other. A sprocket is provided at one end of the reciprocating screw, and a chain is provided between the two sprockets. It is used to drive a driving motor to rotate one of the reciprocating screws, and the nut seat 55 is threadedly sleeved on the reciprocating screw.

[0043] The cross-rail bar 3 passes through the cross-slot 52 transversely, and the cross section of the cross-rail bar 3 matches the cross section of the cross-slot 52 .

[0044] The comb teeth 53 are slidably sleeved in the water-passing groove 4 , and the top of the comb teeth 53 is an inclined surface.

[0045] Both sides of the outside of the support horizontal bar 51 are inclined surfaces, and the support horizontal bar 51 is slidably arranged in the primary filter box 1.

[0046] With such a design, the two nut seats 55 can be driven by the driving member 56 to move back and forth synchronously in the same direction between the two garbage dumping chutes 2. The nut seat 55 drives the connecting rod 54, the supporting horizontal bar 51 and the comb groove teeth 53 to move synchronously. The horizontal bar 3 preliminarily filters the sewage discharged from the sewage pipe 7, so that the relatively large volume of garbage carried in the sewage is filtered out. The reciprocating supporting horizontal bars 51 and the comb groove teeth 53 can push the garbage filtered out from the top of the horizontal bar 3 into the collection boxes 9 on both sides of the primary filter box 1, and simultaneously clean out the garbage stuck in the water gutter 4, so as to avoid the garbage being retained on the top of the horizontal bar 3 or in the water gutter 4 and affecting the preliminary filtering effect and drainage effect of the sewage.

[0047] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the outer support frame 6 is located at the top of the primary filter box 1, and the outer support frame 6 spans both sides of the outside of the primary filter box 1. Such a design can enable the chip discharge port of the sewage pipe 7 to be aligned with the center of the filter surface, so that the continuously discharged sewage can flow smoothly through the filter surface, reducing the impact of garbage accumulation on the filter surface on the sewage pass rate, avoiding the problem of sewage retention and accumulation on the filter surface, improving the sewage filtration efficiency, and also preventing sewage from splashing to the outside of the primary filter box 1.

[0048] like Figure 2 、 Figure 3 and Figure 5As shown, the sewage treatment device also includes a dosing box 10 fixed on the outer support frame 6 and a sealing plate 11 that is laterally rotated and arranged at the bottom of the dosing box 10. The sealing plate 11 is used to seal the medicine outlet at the bottom of the dosing box 10, and an extension rod 12 is fixed on the sealing plate 11.

[0049] The length of the extension rod 12 is greater than the distance between the connecting rod 54 close to the dosing box 10 and the sealing plate 11 .

[0050] With this design, the extension rod 12 can be deflected to a certain angle during each reciprocating movement of the supporting horizontal bar 51, and the sealing plate 11 can be intermittently opened, so that the dosing box 10 can add sewage treatment powder into the sewage. The structure is simple, the dosing operation is convenient and efficient, and the subsequent sewage treatment operation is convenient.

[0051] Working principle: The sewage pipe 7 discharges sewage to the filter surface formed by several horizontal bars 3 distributed in parallel. The sewage and relatively small particulate garbage will flow into the bottom of the primary filter box 1 from the water flow groove 4 and be discharged to the next sewage treatment equipment through the drain pipe 8. Larger garbage mixed in the sewage will remain on the filter surface, and a small amount of flexible garbage such as plastic bags and packaging bags will be entangled or hung on the horizontal bars 3. The two nut seats 55 are driven by the driving member 56 to move back and forth synchronously in the same direction between the two garbage dumping troughs 2. The nut seat 55 drives the connecting rod 54, the supporting horizontal bar 51 and the comb groove teeth 53 to move synchronously, so as to remove the solid garbage falling on the filter surface, the flexible garbage entangled and hanging on the horizontal bar 3 and the particles stuck in the water flow groove 4. The garbage is pushed into the garbage dump 2 simultaneously, and falls from the garbage dump 2 into the collection box 9, completing the centralized collection of garbage for subsequent centralized cleaning. By designing the two sides of the supporting horizontal bar 51 and the outer side of the comb groove teeth 53 as inclined surfaces, the effect of garbage horizontal pushing and cleaning can be effectively improved, and the problems of garbage blocking and jamming during the horizontal pushing process can be effectively avoided, thereby improving the continuity of the garbage horizontal pushing and cleaning action. Each time the connecting rod 54 passes under the outer support frame 6, the connecting rod 54 will push the extension rod 12 to deflect by a certain angle, and the two adjacent deflection directions of the extension rod 12 are opposite, so that the dosing box 10 can be opened intermittently, so that it can relatively evenly add an appropriate amount of sewage treatment agent to the sewage. The operation is simple and efficient, and the amount of agent added each time is relatively uniform.
