Description

Tobacco vacuum tank with unpowered rotary cleaning and drying device

Technical Field

The invention relates to the technical field of cleaning of tobacco vacuum tanks, in particular to a tobacco vacuum tank with an unpowered rotary cleaning and drying device.

Background

In the production process of tobacco enterprises, the volume of demand of cigarette package equipment to the negative pressure is very big, and tobacco vacuum pump system is the supporting service on cigarette package equipment, and three or many vacuum pump units sharing buffer tank, because cigarette package equipment can produce a large amount of ashes, the dust when normal production, and partly ash, the dust can be along with the vacuum pipe inhales in the buffer tank, ash, the dust just also adsorbs on the inner wall of buffer tank easily, in time, can be amasss more and more, consequently, the cleanness to the vacuum pump buffer tank, the maintenance is the essential link in the vacuum pump system maintenance in-process.

At present, the common cleaning and maintenance mode is mainly that an operator detaches a buffer tank maintenance observation hole and enters the buffer tank, tap water is used for washing the interior of the buffer tank, and the buffer tank belongs to limited space operation, so that the interior has large peculiar smell, is stuffy, has long operation time and large labor intensity, and has great influence on the respiratory system of people by cigarette ash and smoke; the flowing ash sludge causes secondary pollution on the ground, which not only affects the field management and equipment management, but also more importantly affects the health of maintenance personnel. In view of the above, some enterprises have improved the above, for example, patent No. CN201754533 discloses a buffer cleaning device for a tobacco vacuum tank, which comprises a tank body, a variable speed motor, a wall scraping bracket, a spray head and the like, wherein the variable speed motor is newly installed at the top of the tank body, and a larger wall scraping bracket is installed inside the tank body. Through opening variable speed motor, drive and scrape the rotation of wall support, scrape a plurality ofly on the wall support drive support surface and scrape the brush with the inboard laminating of the jar body and strike off the filth of jar internal wall, then open one row of shower nozzle of jar internal portion upside, the shower nozzle sprays the running water at a high speed, washs jar internal wall, strikes off and constantly flows to the blowdown ditch through the drain pipe of the drain and the leakage fluid dram of jar body lower part with the filth that washs, borrows this purpose that reaches the washing and the maintenance jar body.

Although the above device has a certain cleaning effect, it has the following disadvantages: firstly, improvements in the construction and performance of the can are not adequate. The device lifts the position of the vacuum air inlet pipe from the lower part of the tank body to the top of the tank body, changes the movement track of the gas and greatly reduces the buffer effect of the gas in the tank body. Secondly, because the tank body has a large volume, the diameter is about 1.4-1.8 m, and the height is 4-5 m, a motor is arranged at the top of the tank body, a wall scraping support which is approximately equal to the diameter of the tank body is arranged in the tank body, the material is wasted, and the processing cost is greatly increased. Thirdly, cigarette ash, smoke and dust flow along with the air current easily, and cigarette ash, the smoke and dust that move along with the air current also attach to on the upper half inner wall surface of jar body easily, but this device can only clean the inner wall attachment of lower half, can't clean the inner wall attachment of upper half, can't accomplish 360 degrees no dead angles and clean. Fourthly, the mechanism only focuses on partial cleaning of the tank body, after the cleaning with water is neglected, a large amount of water stains can be remained on the surface of the inner wall of the buffer tank, the remained water stains can not be effectively removed, the water stains can remain in the tank body for a long time due to the fact that the inside of the tank body is not ventilated, and when the vacuum pump operates, the water stains are easily brought into the vacuum pump by air flow. Fifthly, the cleaned sewage continuously flows to a sewage drainage ditch through a sewage discharge port at the lower part of the tank body and a discharge pipeline of a liquid discharge port, so that not only is a large amount of tap water wasted, but also secondary pollution is caused to the ground and the surrounding environment along with the ash and sludge flowing out of the tap water.
