Description

Technical Field

[0001] The utility model relates to the field of kitchen waste water treatment, in particular to a self-cleaning heating device. Background Art

[0002] Kitchen waste water generally contains oil and waste residue. To avoid the phenomenon of oil solidification during the sewage treatment process, a heating device is required for heating. After the heating device is used for a period of time, due to the slow adsorption and caking of oil residue and sludge around the heating element of the heating device, the effect of the heating device is seriously affected over time. As a result, the temperature control system probe fails to detect that the temperature of the heating source reaches the set value. Therefore, the long-term heating with errors greatly reduces the service life of the heating device and also causes unnecessary power waste. Cleaning is time-consuming and laborious when needed, especially when cleaning some equipment such as mixing tanks and enclosed boxes. It is more difficult to clean, requiring workers to climb into the tanks and boxes, and there is a high risk of operation safety. Content of the Utility Model

[0018] Next, in combination with the drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0019] Refer to Figures 1-3, a self-cleaning heating device, comprising a heating element 1 and a base 2 fixed at the end of the heating element 1. A power supply port 12 is provided on the base 2 for supplying power to the heating element 1, and a cleaning assembly 3 is provided on the heating element 1. The cleaning assembly 3 includes a cleaning part and an actuating part. The actuating part is arranged inside the base 2, sleeved on the heating element 1 and reciprocates along the length direction of the heating element 1. And the cleaning part is in contact with the outer wall of the heating element 1. One end of the actuating part passes through the base 2 and is connected to the cleaning part, for driving the cleaning part to reciprocate along the length direction of the heating element 1. The actuating part is inside the base 2. During use, pull the actuating part by hand to drive the cleaning part to move along the length direction of the heating element 1. During the movement, the cleaning part always abuts against the outer wall of the heating element 1, so as to scrape off the pollutants adhered to the outer wall of the heating element 1, enabling the heating element 1 to recover cleanliness and improving the heating efficiency. At the same time, only by driving the actuating part can the heating element 1 be cleaned, which is simpler.

[0020] The cleaning part includes a scraper 31, the scraper 31 is connected to the actuating part, and a through hole 32 for the heating element 1 to pass through is provided on the scraper 31. When the heating element 1 passes through the through hole 32, the inner wall of the through hole 32 is in contact with the outer wall of the heating element 1. When the scraper 31 moves along the length direction of the heating element 1, the scraper 31 abuts against the side wall of the heating element 1, for scraping the outer wall of the heating element 1. Further, the heating element 1 can be a collection of several heating tubes 11, then a through hole 32 is opened on the end face of the scraper 31 corresponding to each heating tube 11, and each heating tube 11 correspondingly passes through a through hole 32, and the inner wall of the through hole 32 abuts against the outer wall of the heating tube 11. That is, no matter what shape the heating element 1 is, the inner wall of the through hole 32 needs to fit the outer wall of the heating tube 11 to make the scraping effect of the scraper 31 on the dirt the best. Similarly, by driving the actuating part to move, the scraper 31 is driven to move along the length direction of the heating tube 11. During the movement, since the scraper 31 is close to the outer wall of the heating tube 11, the pollutants adhered to the outer wall of the heating tube 11 can be scraped off during the movement, enabling the heating tube 11 to remain clean.

[0021] The actuating part includes a cable 33. One end of the cable 33 placed inside the base 2 is provided with a limiting member. The other end of the cable 33 passes through the base 2 in the direction of the heating element 1 and is connected to the scraper 31. An installation cavity 21 is formed on the base 2, and a through hole 34 is formed at the bottom of the installation cavity 21. The cable 33 passes through the through hole 34, and the limiting member abuts against the bottom of the installation cavity 21. The limiting member includes a pull ring 35, and the pull ring 35 is fixedly connected to the cable 33. The pull ring 35 abuts against the bottom of the installation cavity 21. An inspection cover 4 is provided at the opening of the installation cavity 21, and the inspection cover 4 covers the installation cavity 21 to seal the installation cavity 21. An insulating layer 36 is provided at the bottom of the installation cavity 21, and the insulating layer 36 is placed between the limiting member and the bottom of the installation cavity 21. When cleaning is required, only the inspection cover 4 needs to be opened to expose the pull ring 35. Then, the pull ring 35 is pulled, so that the scraper 31 moves. During the movement, the scraper 31 always abuts against the outer wall of the heating element 1, and the garbage adhered to the outer wall of the heating element 1 can be easily scraped off, so that the surface of the heating element is restored to cleanliness. The cleaning operation is simple, more convenient and faster.

[0022] Compared with the prior art, when cleaning is required for the present utility model, only the inspection cover 4 needs to be opened to expose the pull ring 35. Then, the pull ring 35 is pulled, so that the scraper 31 moves. During the movement, the scraper 31 always abuts against the outer wall of the heating element 1, and the garbage adhered to the outer wall of the heating element 1 can be easily scraped off, so that the surface of the heating element is restored to cleanliness. The cleaning operation is simple, more convenient and faster.
