Embodiment 1

[0031] see Figure 1-4, a reciprocating filtering and scraping equipment, including a collection cylinder 1 and a turntable 2 located in the collection cylinder 1, the turntable 2 and the inner periphery of the collection cylinder 1 rotate and cooperate, and adopt a common rotating and sealing structure, and the turntable 2 can completely seal The function of the partition; the top of the collection cylinder 1 is provided with an integrated conical sleeve 11, and the collection cylinder 1 replaces the sludge tank in the middle of the bottom of the large and medium-sized sewage sedimentation tank through the conical sleeve 11 to collect sludge. The sleeve 11 is fixed with a cross dividing plate 111 on the upper part of the turntable 2. The cross dividing plate 111 divides the sludge entering the collection tube 1 into four equal parts, and can prevent the sludge from following when the turntable 2 rotates at the bottom of the sludge. The turntable 2 rotates, that is to say, whe...

Embodiment 2

[0033] see image 3 The difference from Embodiment 1 is that an arc plate 35 distributed concentrically with the cylindrical body of revolution 3 is fixedly connected between two adjacent fin plates 33 located at both ends of the cylinder body of revolution 3 , and the arc plate 35 The function is to increase the effect of water resistance. For example, when the sludge concentration in the collection tube 1 is at the lowest state, the rotation of the turntable 2 is controlled. If the arc plate 35 is not provided, the cylindrical rotary body 3 is difficult to swing phenomenon, it is not convenient to realize the self-flushing of the mud scraping equipment at this time, by setting the arc plate 35, when the control turntable 2 rotates at a high speed, the arc plate 35 will increase the water resistance, and then drive the cylindrical rotating body 3 to swing Therefore, one of the arc-shaped mud guide grooves 34 communicates with the upper part and the lower part of the turntable...

Embodiment 3

[0035] see Figure 5 The difference from Embodiment 1 is that the top of each vertical plate on the cross partition 111 is fixedly provided with a drainage plate 112, and the top of the drainage plate 112 is provided with a drainage channel 1121, and the bottom of the drainage channel 1121 extends into the gap 1111, The mouth of the drainage channel 1121 is equipped with a filter screen 6, and the mouth of the drainage channel 1121 has two positions, the top and the bottom. When the sludge in the collection tube 1 is concentrated and transitional, or the sludge fluidity is poor, the drainage channel 1121 can remove the sediment The supernatant water at a high place in the pool is introduced into the sludge, and by controlling the swing of the turntable 2, the supernatant water will be guided into the sludge with poor fluidity under the drainage of the drainage channel 1121, so as to improve the fluidity of the sludge and facilitate the implementation of Example 1. Operation, t...

Abstract

The invention discloses a reciprocating filtering mud scraping device, which comprises a collection cylinder and a rotating disk located in the collection cylinder. In the present invention, the sludge accumulation tank at the bottom of the large and medium-sized sedimentation tank is replaced with the cost equipment. This equipment includes a collection cylinder, a turntable is arranged in the collection barrel, and a cylindrical rotating body uniformly distributed in the circumferential direction is arranged on the rotating disk. The outer wall of the cylindrical rotating body and The upper part of the turntable is equipped with axially arranged fin plates, and the outer wall of the cylindrical rotary body is provided with symmetrically distributed arc-shaped mud guide grooves on both sides of the arranged fin plates, in which the cylindrical rotary body is elastically oscillating. The upper end surface of the turntable is in contact with the settled sludge, and the fin plate plays the role of controlling the swing and reset of the cylindrical rotary body according to the water content of the sludge in the collection tube. The mud is scraped and separated into the lower part of the turntable, which is convenient for the sewage pump to discharge, otherwise the arc-shaped mud guide groove is in a closed state.

Description

technical field [0001] The invention relates to the technical field of sewage sedimentation treatment, in particular to a reciprocating filtering and scraping equipment. Background technique [0002] Sewage contains mixed impurities. Sewage is usually treated before it can be discharged. Sewage contains sludge. During the process of sewage treatment, sludge will accumulate on the surface in contact with sewage, such as sewage sedimentation tanks, sewage filtration barrels, etc., which require the use of mud scraping equipment for cleaning; [0003] At present, the bottom of the sewage sedimentation tank usually accumulates a large area of ​​sludge, which needs to be scraped with the help of scraper equipment. The purpose of scraping the sludge is to scrape the sludge covered by a large area into the sludge tank located in the center. Then the sludge is discharged to the outside by a pneumatic pump, and the supernatant water is discharged through the top of the sedimentation...
