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 fixed 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 or the fluidity of the sludge 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, to ensure that the slud...

Abstract

The invention discloses reciprocating type filtering and mud scraping equipment. The equipment comprises a collecting cylinder and a rotating disc located in the collecting cylinder. In the present invention, sludge gathering tanks at the bottoms of large and medium-sized sedimentation tanks are replaced with cost equipment; the equipment comprises the collecting cylinder, a rotary table is arranged in the collecting cylinder, cylindrical rotary bodies which are evenly distributed in the circumferential direction are arranged on the rotary disc. Fin-shaped plates which are axially arranged anddistributed are arranged on the outer surface wall of the cylindrical revolving bodies and positioned at the upper part of the rotary disc; symmetrically distributed arc-shaped mud guide grooves areformed in the outer surface wall of the cylindrical revolving bodies and located in the two sides of the fin-shaped plates which are arranged and distributed, wherein the cylindrical revolving body isarranged in an elastic swinging manner; the upper end face of the rotary disc makes contact with settled sludge, the fin-shaped plates play a role in controlling the cylindrical revolving bodies to swing and reset according to the water content of the sludge in the collection barrel, when the water content is small, the arc-shaped sludge guide grooves scrape the sludge from the bottom of the sludge layer and separate and guide the sludge into the lower portion of the rotary disc, and thus the sewage pump can discharge the sludge conveniently, otherwise, the arc-shaped mud guide groove is in the 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...
