Description

Technical Field

[0001] The utility model relates to the technical field of oil-water separators, in particular to a self-cleaning oil-water separator. Background Art

[0002] Oil substances have many impacts on the environment. For example, they pollute water bodies and form oil films on the water surface, which can hinder the reoxygenation of water bodies. Due to the reduction of dissolved oxygen in the water, algae photosynthesis is restricted, affecting the normal growth of aquatic organisms, making aquatic plants and animals have an oily or toxic smell, and even making the water smelly, destroying the utilization value of water resources.

[0003] A lot of oily wastewater is generated in the kitchen, and the oil needs to be separated through an oil-water separator. Since the content of food residues in catering is very high, the oily wastewater needs to be filtered first. During the filtering process, the filter plate will be blocked by the accumulated residues, affecting the normal operation of the equipment. It needs to be cleaned regularly, but the existing equipment is not effective in cleaning the residues, and manual assistance is required for cleaning, and the equipment needs to be shut down for cleaning.

[0016] As a further solution of the utility model:

[0017] Both sides of the lower end of the scraper are inclined surfaces corresponding to the second spring, so that the scraper can be elastically extended and retracted when located at the edge of the filter plate.

[0018] As a further solution of the utility model:

[0019] The spring seats on both sides of the box body are fixedly connected through a support plate, and are connected to the driving member through the support plate.

[0020] As a further solution of the utility model:

[0021] The driving member includes a screw rod rotatably arranged at a corresponding position of the top wall of the box body, and a motor installed at the outer end of the box body. The motor is connected to the screw rod in a transmission manner. A screw sleeve threadedly connected to the screw rod is fixedly provided on the support plate. The motor controls the rotation of the screw rod to drive the support plate to move back and forth, thereby causing the scraper to scrape back and forth on the filter plate.

[0022] Compared with the prior art, the utility model has the following beneficial effects: side plates are elastically provided on both sides of the filter plate to close both sides of the filter plate and prevent oily wastewater from entering the slag discharge channel. When the scraper moves to the edge of the filter plate, the second slider pushes the first slider to move outward, so that the side plate opens the gap in advance, allowing debris and residue to be introduced into the slag discharge channel. The reciprocating movement of the scraper can effectively remove the debris and residue on the filter plate and improve the filtration efficiency of sewage. The scraper is elastically arranged on the spring seat to avoid hard contact between the scraper and the filter plate, and the bottom of the scraper can be attached to the filter plate to improve the stability of scraping.

[0031] This embodiment provides a self-cleaning oil-water separator, comprising a box body 1 and collection barrels 11 arranged on both sides of the box body 1, wherein the upper end of the box body 1 is provided with a sewage inlet 12, and a filter plate 13 for filtering sewage is arranged in the box body 1, and the lower end of the filter plate 13 is a grease separation chamber 14 for separating grease;

[0032] The upper side of the box body 1 is symmetrically provided with slide rails 15 on both sides, and the box body 1 is elastically provided with side plates 2 on both sides of the filter plate 13. The side plates 2 are slidably mounted on the slide rails 15 and are arranged against the outside of the filter plate 13 to prevent sewage from escaping outward. The outer end of the side plate 2 is provided with a slag discharge channel 16, and the residue is introduced into the collection bucket 11 through the slag discharge channel 16.

[0033] The box body 1 is provided with a scraping assembly for cleaning the filter plate 13, and the scraping assembly includes a sliding member slidably mounted on a slide rail 15, a driving member for pushing the sliding member to move, and a scraper 3 elastically arranged on the sliding member, and the lower end of the scraper 3 is elastically pressed against the filter plate 13 to scrape the filter plate 13.

[0034] In this embodiment, first sliders 21 are respectively provided on both sides of the side plate 2, and the side plate 2 is slidably installed on the slide rail 15 through the first sliders 21. The side plate 2 is arranged on the side of the first slider 21 away from the filter plate 13, so that when the sliding member is against the first slider 21, the side plate 2 can be pushed to move outward to open the gap and allow the residue to enter the slag discharge channel 16.

[0035] The side of the side plate 2 away from the filter plate 13 is provided with a first spring 22 in contact with the inner wall of the box body 1, and the side plate 2 and the inner wall of the box body 1 are respectively provided with positioning columns corresponding to the first spring 22. The first spring 22 is sleeved on the outer end of the positioning column, so that the side plate 2 elastically contacts the outer side of the filter plate 13.

[0036] In this embodiment, the sliding member includes a second slider 31 slidably mounted on the slide rail 15 and a spring seat 32 arranged at the outer end of the second slider 31. Pressure rods 33 are fixedly provided on both sides of the scraper 3 corresponding to the spring seats 32, and the pressure rods 33 are inserted into the spring seats 32 for sliding connection.

[0037] The spring seat 32 is provided with a slide groove, the pressure rod 33 is provided with a pressure plate 34 in the slide groove, the pressure plate 34 is slidably connected in the slide groove, and a second spring 35 is provided at the upper end of the pressure plate 34, and the spring is elastically connected to the pressure plate 34.

[0038] Both sides of the lower end of the scraper 3 are inclined surfaces corresponding to the second spring, so that the scraper 3 can be elastically retracted when located at the edge of the filter plate 13.

[0039] The spring seats 32 on both sides of the box body 1 are fixedly connected through support plates 36 and are connected to the driving member through the support plates 36 .

[0040] In this embodiment, the driving member includes a screw 37 rotatably arranged at a corresponding position on the top wall of the box body 1, and a motor 38 installed at the outer end of the box body 1. The motor 38 is connected to the screw 37 in a transmission manner. A screw sleeve 39 threadedly connected to the screw 37 is fixed on the support plate 36. The motor 38 controls the rotation of the screw 37 to drive the support plate 36 to move back and forth, so that the scraper 3 scrapes back and forth on the filter plate 13.

[0041] The working principle of the utility model is as follows: oily wastewater is introduced into the box body 1 through the sewage inlet 12 and filtered through the filter plate 13, and debris and residues are accumulated on the upper end of the filter plate 13. The motor drives the screw 37 to rotate forward and reverse in sequence, thereby pushing the scraper 3 to move back and forth on the filter plate 13 through the support plate 36. When the scraper 3 moves to the edge of the filter plate 13, the second slider 31 pushes the first slider 21 to move outward, so that the side plate 2 opens the gap in advance, allowing the debris and residue to be introduced into the slag discharge channel 16. The inner wall of the box body 1 is provided with an in-place sensor for detecting the position of the first slider 21, so as to control the motor to reverse through the controller to avoid excessive squeezing of the first slider 21, and the debris and residue fall into the collection bucket 11 through the slag discharge channel 16.
