Description

Technical Field

[0001] The present invention relates to sewage treatment, in particular to a catering sewage slag removal device and a working method thereof. Background Art

[0002] With the continuous development of urbanization, the problem of domestic pollution has become more and more prominent, causing a considerable impact on the urban environment. Among them, the treatment of catering sewage has always been one of the most prominent problems. In order to solve the problem of catering sewage, the prior art has also disclosed a number of treatment equipment. Most of these treatment equipment adopt slag filtration, sedimentation, multi-stage oil-water separation, biological treatment and decomposition to achieve the desired effect. Among them, slag filtration is often the first step and plays a particularly important role. There are many existing slag filtration methods, the more common ones are filter slag removal, spiral slag removal, centrifugal slag removal, etc. Among them, filter slag removal is the simplest and most effective, and the cost is also low, but it requires manual regular cleaning, which is time-consuming and labor-intensive to operate, and the filtration and slag removal operation needs to be suspended during cleaning, affecting normal sewage treatment. Spiral slag removal and centrifugal slag removal have a higher degree of automation and a good treatment effect, but the investment cost is relatively large, and regular maintenance and cleaning are also required in the later stage, and disassembly is relatively inconvenient. For this reason, the existing slag filtration structure and slag removal method need to be improved. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the present invention aims to provide a restaurant wastewater deslagging device and its operating method to the art, thereby resolving the technical problem that existing deslagging equipment structures are difficult to achieve in terms of both cost and convenience in automatic deslagging. This objective is achieved through the following technical solution.

Through the above structure, the flat filter plate is used to realize slag removal and filtration in the initial state, and the flipping of the flat filter plate is controlled to realize the dumping operation of the slag material, which is simple and convenient to operate and has a good slag removal effect; and when dumping, the curved filter plate replaces the flat filter plate to realize slag removal and filtration, thereby ensuring the normal operation of sewage treatment without interruption.

[0005] The flat filter plate's filter surface is equipped with a scraper plate that oscillates to scrape residue from the filter surface into the residue discharge channel. A first oscillating motor is fixed to the back of the flat filter plate, driving the scraper plate's oscillation. This structure enables electric scraping, resulting in a high degree of automation and further improving the removal of residue from the flat filter plate.

[0006] The filter surface of the flat filter plate is equipped with at least two sets of synchronously swinging scraper plates, and all the scraper plates are hinged to swing synchronously via a transverse connecting rod. This structure facilitates the cleaning operation of slag materials on flat filter plates of different sizes.

[0007] The swing handle is replaced by a second swing motor, which is fixed to the outer side of the box body. Through this structure, the automatic flipping operation of the flat filter plate is realized, which is labor-saving and highly automated.

[0008] An electric hoist for pulling the flat filter plate to flip is fixedly provided on the top of the box body, that is, the rope of the electric hoist is connected to the flat filter plate.

[0022] The present invention will now be further described with reference to the accompanying drawings.

[0023] like Figure 1-5As shown, the main body of the catering wastewater deslagging equipment is a box body 1 with a liquid inlet 101 on the top, and the box body includes a liquid inlet diversion chamber 102 and a liquid storage chamber 104. The liquid inlet diversion chamber is located on one side above the liquid storage chamber, and the liquid inlet is located at the top center of the liquid inlet diversion chamber. A diversion plate 106 is provided in the liquid inlet diversion chamber to divert the sewage entering the liquid inlet, and a diversion slope 103 is provided at the bottom of the liquid inlet diversion chamber to guide the liquid to the top of the liquid storage chamber. A flat filter plate 2 is provided above the liquid storage chamber to filter the sewage flowing into the liquid storage chamber from the diversion slope, that is, the flat filter plate is provided with a filter hole for filtering the residue, and the flat filter plate is set to be flipped relative to the box body with one end as a hinge axis, and one end of the hinge axis extends out of the box body and is fixedly connected to a swing handle or a second swing motor 6, and the swing handle or the second swing motor drives the flat filter plate to flip, and the second swing motor is fixedly connected to the box body. The other end of the flat filter plate is provided with an arc-shaped filter plate 3 extending downward toward the liquid storage chamber. The arc-shaped filter plate is provided with a filter hole for filtering residue. An upper limit block 301 and a lower limit block 302 are respectively provided at each end of the arc-shaped filter plate to limit the flipping angle of the flat filter plate. When the flat filter plate is not flipped, the upper limit block of the arc-shaped filter plate overlaps the upper edge of the end of the guide slope at the bottom of the liquid inlet guide chamber. When the flat filter plate is flipped upward into position, the lower limit block of the arc-shaped filter plate overlaps the lower edge of the end of the guide slope at the bottom of the liquid inlet guide chamber. When the arc-shaped filter plate flips with the flat filter plate, the filtering surface of the arc-shaped filter plate always abuts and fits with the end of the guide slope at the bottom of the liquid inlet guide chamber, forming a closed state. A slag discharge channel 105 is provided on the other side of the casing above the liquid storage chamber. The flip hinged end of the flat filter plate corresponds to this slag discharge channel, that is, when the flat filter plate is flipped, the slag falls into this slag discharge channel.

[0024] The flat filter plate 2 is equipped with a scraper plate 4 on its filtering surface, which oscillates to scrape the residue from the surface into a slag discharge channel. A first oscillating motor 5, which drives the oscillating movement of the scraper plate, is fixed to the back of the flat filter plate via a bracket. Two sets of synchronously oscillating scraper plates are installed on the filter surface of the flat filter plate. Both sets of scraper plates are connected to a hinged transverse connecting rod 8 for synchronized oscillation. That is, when one set of scraper plates is oscillated by the first oscillating motor, the other set of scraper plates, driven by the transverse connecting rod, simultaneously oscillates and scrapes the residue.

[0025] In addition to using the external second swing motor 6 or the swing handle to drive the swing of the above-mentioned flat filter plate 2, the same purpose can also be achieved through the following two solutions. The first solution ( Figure 6 In the first embodiment, an electric hoist 8 is fixed to the top of the housing 1 to pull and flip the flat filter plate. The rope of the electric hoist is connected to the flat filter plate, and the electric hoist is used to pull and flip the flat filter plate. In the second embodiment (not shown), an electric cylinder is installed at the top of the housing to pull and flip the flat filter plate. One end of the cylinder body of the electric cylinder is movably hinged to the top of the housing, and the push rod end of the electric cylinder is movably hinged to the flat filter plate. The flat filter plate is flipped by the extension and contraction of the electric cylinder.

[0026] In order to reduce the problem of slag blocking between the two sides of the flat filter plate 2 and the inner wall of the box body 1, slag blocking baffles are provided on both sides of the flat filter plate.

[0027] In order to facilitate the cleaning and maintenance of the flat filter plate 2 and the curved filter plate 3, the flat filter plate and the curved filter plate can also be designed as detachable filter screens.

[0028] The working method of the above-mentioned catering sewage slag removal equipment is as follows: sewage enters the liquid inlet 101 of the box body 1, and after the sewage is diverted by the diverter plate 106, it is guided into the flat filter plate 2 by the guide slope 103 at the bottom of the liquid inlet guide chamber 102, and the flat filter plate filters the sewage and removes the slag. The sewage after slag removal enters the liquid storage chamber 104, and the slag accumulates on the flat filter plate; when it is necessary to clean the slag on the flat filter plate, the flat filter plate is driven to flip over to the lower limit block 302 of the arc filter plate by the swing handle or the second swing motor 6, and the lower edge of the end of the above-mentioned guide slope is restrained, and the flat filter plate is in an inclined and inverted shape; at this time, the first swing motor 5 is turned on to drive the scraper plate 4 to perform the scraping operation, so that the slag on the flat filter plate fully falls into the slag discharge channel 105, and is collected by the external collection box after passing through the slag discharge channel. When the flat filter plate is cleaning the residue, the sewage in the liquid inlet diversion chamber is filtered and deslagging through the curved filter plate. The sewage after deslagging enters the liquid storage chamber, and the residue accumulates in the liquid inlet diversion chamber. After the residue on the flat filter plate is cleaned, the flat filter plate is reset so that the upper limit block of the curved filter plate overlaps the upper edge of the end of the diversion slope at the bottom of the liquid inlet diversion chamber. The filtration by the curved filter plate is switched back to the flat filter plate, and the residue in the liquid inlet diversion chamber will re-enter the flat filter plate with the sewage for deslagging filtration. The above method is repeated to realize the deslagging and filtration operation of the catering sewage deslagging equipment.

[0029] The above content is intended to illustrate the technical means of the present invention and is not intended to limit the technical scope of the present invention. Those skilled in the art may make obvious improvements or substitutions to the present invention in combination with existing common knowledge, which also fall within the scope of protection of the claims of the present invention.
