Abstract
The utility model discloses a jar body (mixing) shaft sealing device, this equipment fixing in vertical jar body equipment top, wherein (mixing) shaft sealing device includes: base, (mixing) shaft, stirring axle sleeve, support, bearing, liquid seal structure constitute, and wherein the liquid seal structure is cut off by outer backplate, inlayer backplate, centre and is constituteed, the utility model provides a jar body (mixing) shaft sealing device aims at solving long-distance (mixing) shaft and jar body internal gas leakage condition of frequently causing the emergence of jar body internal gas leakage condition frequently that the sealing washer is damaged when stirring for large-scale jar body (mixing) shaft swing range greatly causes of (mixing) shaft, prevents to take place the incident.
Description
Technical Field
The utility model relates to an agitator tank processing technology field, in particular to jar body (mixing) shaft sealing device.
Background
The biological reaction jar needs to carry out abundant mixing to jar interior material in the use, and the (mixing) shaft is biological reaction jar's important component part, plays the effect of mixed material, regulation reaction rate. When involving large-scale biological reaction jar, the epaxial blade of stirring often has longer distance apart from the motor, and the moment of conducting the motor during rotation is great, causes the motor wrench movement easily, destroys the sealing member between motor (mixing) shaft and the jar body, and it is high to change cost of maintenance, influences normal production.
The main material of the existing stirring shaft sealing device is a rubber ring, and the rubber ring is pressed on a base between the stirring shaft and the tank body to play a role in stopping a sealing channel. The elastic deformation of rubber ring is caused in long-time operation for can't closely laminate between rubber ring and the (mixing) shaft base, accelerated the rubber ring wearing and tearing, cause the internal and external gas exchange of jar, cause the safety in production accident easily.
Therefore, it is necessary to design a tank stirring shaft sealing device which can prevent the exchange of gas inside and outside the tank even if the stirring shaft sealing element is damaged, and reduce the failure rate of equipment.
Disclosure of Invention
An object of the utility model is to provide a jar body (mixing) shaft sealing device to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a jar body (mixing) shaft sealing device, this equipment is installed in vertical jar of body equipment top, and jar body (mixing) shaft sealing device comprises base, (mixing) shaft, stirring axle sleeve, stirring axle support, bearing, liquid seal structure.
Preferably, the tank is a facility for preventing the exchange of internal gas with external air, and includes but is not limited to a bioreactor such as an anaerobic fermentation tank, a material conditioning tank, and the like, a volatile liquid storage, and the like.
Preferably, the stirring shaft is connected with the tank body through the base, a bearing is arranged in the base to bear lateral pressure caused by the movement of the stirring shaft, and a sealing ring is not arranged between the stirring shaft and the base.
Preferably, the stirring shaft sleeve is connected with the tank body through a support, so that the motor and the stirring shaft are fixed, and the motor is prevented from laterally falling due to the movement of the stirring shaft.
Preferably, the liquid seal structure is composed of an outer layer protection plate, an inner layer protection plate and a middle partition, and a liquid storage space is formed.
Preferably. The middle partition is connected with the stirring shaft sleeve through a bearing, and the middle partition keeps a static state when the stirring shaft rotates.
Preferably, the liquid filled in the liquid storage space is a material which does not change the gas inside the tank body, and the material includes, but is not limited to, water, oil and organic solvent.
The utility model discloses following beneficial effect has: the liquid seal is adopted to isolate the gap between the stirring shaft of the sealed tank body and the tank body from the external atmospheric environment, so that gas leakage caused by damage of the sealing device between the stirring shaft and the tank body due to rotation of the stirring shaft of the stirring motor arranged on the upper part of the sealed tank body is avoided.
