Problems solved by technology

Because the gas (exhaust gas) discharged from the coating machine contains a lot of dust with different diameters, some extremely fine dust is not easy to be filtered by the bag; and after a certain period of use, there will be a lot of syrup on the bag, which affects the air quality. The processing capacity and the negative pressure in the coating pan
For this reason, filter cloth bags need to be replaced regularly, which wastes time and labor, thereby affecting work efficiency and increasing costs

Embodiment Construction

[0009] refer to figure 1 As can be seen, the present invention is applied to a water curtain dedusting mechanism of a coating machine, comprising a housing 10, an atomizing shower head 5 is housed at an upper inlet 13 in the housing 10, and in the housing 10, and An air pipe 6 is installed near the bottom of the atomizing shower head; a water-gas separation device 7 is installed in the housing 10 and at the outlet of the air pipe 6, and the bottom of the housing 10 is a water accumulation area 9.

[0010] The upper inlet 13 of the housing 10 is connected to the tangential separation device 1 , and the tangential separation device 1 has a tangential inlet 15 thereon. The water replenishing device 8 is connected outside the housing 10 and at the water accumulation area 9 at the bottom of the housing (through the first pipe 11 ). The circulating spraying device 4 is connected outside the housing 10 and between the water accumulation area 9 at the bottom of the housing and the a...

Abstract

The invention discloses a water curtain dust removing mechanism applicable to a coating machine, which comprises a casing (10). An atomization spraying head (5) is installed at the position of an upper inlet (13) in the casing (10), a gas pipe (6) is installed in the casing (10) and close to the position below the atomization spraying head, a water-gas separation device (7) is installed at the position of an outlet of the gas pipe (6) and in the casing (10), and a pools zone (9) is located at the bottom of the casing (10). The gas pipe (6) is a venturi pipe. The water curtain dust removing mechanism is good in dust filtering effect, simple in operation, convenient in replacement, low in labor strength, high in work efficiency and capable of effectively ensuring gas handling capacity and negative pressure in a coating pan.

Description

technical field [0001] The invention relates to a kind of pharmaceutical and food machinery equipment, in particular to a mechanism for filtering and dust-removing the gas discharged from the coating machine, which is applied to the coating machine. Background technique [0002] At present, the coating machine is a kind of pharmaceutical equipment that coats the surface of the drug, and the filter and dust removal mechanism uses a cloth bag to filter and remove the dust from the gas discharged from the coating machine. Because the gas (exhaust gas) discharged from the coating machine contains a lot of dust with different diameters, some extremely fine dust is not easy to be filtered by the bag; and after a certain period of use, there will be a lot of syrup on the bag, which affects the air quality. The processing capacity and the negative pressure in the coating pan. For this reason, filter cloth bags need to be replaced regularly, which wastes time and labor, thereby affe...
