Description

A tobacco vacuum tank with a non-powered rotating cleaning and drying device

technical field

The invention relates to the technical field of tobacco vacuum can cleaning, in particular to a tobacco vacuum can with a non-powered rotating cleaning and drying device.

Background technique

In the production process of tobacco companies, the demand for negative pressure on the crimping and packaging equipment is very large, and the tobacco vacuum pump system is a supporting service for the crimping and packaging equipment, and generally three or more vacuum pump units share a buffer tank. Because the crimping and packaging equipment will produce a large amount of soot and dust during normal production, and part of the soot and dust will be sucked into the buffer tank along with the vacuum pipeline, so the soot and dust will be easily adsorbed on the inner wall of the buffer tank. Over time, it will accumulate more and more Therefore, the cleaning and maintenance of the vacuum pump buffer tank is an essential link in the maintenance process of the vacuum pump system.

At present, the commonly used cleaning and maintenance methods are mainly that the operator disassembles the buffer tank to repair the observation hole, enters the buffer tank, and rinses the tank with tap water. Since the buffer tank is operated in a limited space, the interior has a strong odor, is stuffy, and the operation time is long , high labor intensity, soot and smoke have a great impact on the human respiratory system; the outflow of soot and silt causes secondary pollution on the ground, which not only affects on-site management and equipment management, but more importantly, affects the health of maintenance personnel. Taking this into consideration, some companies have improved it, such as the patent No. CN201754533, which discloses a buffer cleaning device for tobacco vacuum tanks, which consists of a tank body, a variable speed motor, a wall scraping bracket and a nozzle, etc. A variable speed motor is newly installed on the top of the tank, and a larger scraper bracket is installed inside the tank. By turning on the variable speed motor, the wall scraper bracket is driven to rotate, and the scraper bracket drives a plurality of scrapers on the outer surface of the bracket that fit inside the tank body to scrape off the dirt on the inner wall of the tank body, and then opens the upper side of the tank body A row of nozzles, the nozzles spray tap water at high speed to clean the inner wall of the tank, and the scraped and cleaned dirt flows continuously to the sewage ditch through the sewage outlet and the discharge pipe of the liquid outlet at the bottom of the tank, so as to achieve cleaning and The purpose of maintaining the tank.

Although the above-mentioned device has a certain cleaning effect, it still has the following defects: the one is that the improvement of the tank structure and work performance is not very appropriate. The device raises the position of the vacuum inlet pipe from the bottom of the tank to the top of the tank, changes the trajectory of the gas movement, and greatly reduces the buffering effect of the gas in the tank. Second, due to the large volume of the tank, the diameter is about 1.4-1.8m, and the height is between 4-5m. It is still a waste of materials to install a motor on the top and a wall-scraping bracket that is roughly equivalent to the diameter of the tank. , greatly increasing the processing cost. The third is that soot and dust are easy to flow with the airflow, and the soot and dust moving with the airflow are also easy to adhere to the upper half inner wall surface of the tank body, but this device can only clean the inner wall attachments of the lower half, and cannot To clean the attachments on the inner wall of the upper part, it is impossible to clean 360 degrees without dead ends. Fourth, this mechanism only pays attention to the partial cleaning of the tank body, but ignores that after cleaning with water, a large amount of water stains will remain on the inner wall surface of the buffer tank, which cannot effectively remove the remaining water stains. If it remains in the tank for a long time, when the vacuum pump is running, the water stains are easily brought into the vacuum pump by the airflow. Fifth, the cleaned dirt flows continuously to the sewage ditch through the sewage outlet and the discharge pipe of the liquid outlet at the lower part of the tank body, which not only causes a lot of waste of tap water, but also causes damage to the ground and the surrounding environment due to the soot and silt flowing out of the tap water. Secondary pollution.
