Description
Technical Field
The utility model relates to a reation kettle, in particular to an anti-pollution mechanical seal device is used to cauldron that can clear up the pollutant on line that is used for trades such as medicine, food.
Background
The reaction kettle is often used in the industries of medicines, foods and the like to synthesize and produce finished products or intermediate products, the requirement of high cleanliness is met, and medium pollution in the reaction kettle is avoided in the production process. The mechanical sealing device of the reaction kettle is characterized in that an end face seal is formed by a movable ring and a static ring, and in the using process, the movable ring and a static ring friction pair generate friction dust and normally leaked lubricating liquid through running friction. If protective measures are not taken, the abrasive dust and the lubricating liquid can gradually enter the reaction kettle to pollute medicines and foods and seriously affect the product quality.
The applicant discloses in a utility model patent specification of patent number ZL201020037732.5 a mechanical sealing device for preventing a reaction kettle medium from being polluted, wherein the mechanical sealing device comprises a movable ring, a stationary ring and a stationary ring seat. Quiet ring and by being provided with the abrasive dust collecting ring between the sealed axle, form the cavity that is used for long-pending abrasive dust that receives between the surface of this abrasive dust collecting ring and the quiet ring inner wall, the vice abrasive dust that produces of rotating ring, quiet ring friction and the lubricated liquid of normal leakage fall into the cavity in the reation kettle operation process, so can avoid the abrasive dust to fall into reation kettle effectively in to ensure that the medium is not contaminated in the reation kettle.
But these abrasive dust and lubricating fluid cannot be automatically cleaned. Over time, if the cleaning is not performed regularly, the increased abrasive dust and the lubricating fluid can overflow into the reaction kettle, and the material in the kettle can be polluted. However, if the pollutants are to be cleaned manually, the equipment needs to be disassembled and disassembled, which has the disadvantages of large workload and inconvenient field maintenance, and can affect the production efficiency of the equipment.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a can online clearance pollutant's anti-pollution mechanical seal device is used to cauldron is provided to the realization is collected the abrasive dust and the lubricated liquid that produce mechanical seal device and can regularly clear up on line, and does not need dismounting device, thereby alleviates on-the-spot maintenance work load greatly.
The utility model provides a technical scheme that its technical problem adopted as follows:
the utility model discloses a can clear up anti-pollution mechanical seal device for cauldron of pollutant on line, including rotating ring, quiet ring and quiet ring holder, quiet ring and by being provided with the abrasive dust collecting ring between the sealed axle, form the cavity that is used for long-pending abrasive dust between the surface of this abrasive dust collecting ring and the quiet ring inner wall, characterized by: a suction channel is arranged in the static ring seat, the inner end of the suction channel is communicated with the cavity, and the outer end of the suction channel is connected with a vacuum suction device.
The beneficial effects of the utility model are that, be provided with the suction passageway that is linked together with the cavity in the quiet ring seat, start vacuum suction device and can in time clear up abrasive dust and lubricated liquid in the cavity, avoid abrasive dust and lubricated liquid in the cavity to get into reation kettle because of the accumulation is too much in, consequently can realize the regular online clearance to the cavity, and need not dismantle equipment to alleviate field maintenance work volume greatly.
Drawings
The specification includes the following figures:
fig. 1 is a schematic structural view of an anti-pollution mechanical sealing device for a kettle, which can clean pollutants on line.
The figure shows the parts, the part names and the corresponding marks: the device comprises a moving ring 1, a static ring 2, a static ring seat 3, an abrasive dust collecting ring 4, a cavity 5, a suction channel 6, a pipeline 7, a normally closed valve 8, a movable vacuum suction machine 9 and an observation sight glass 10.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Referring to fig. 1, the utility model discloses a but cauldron of online clearance pollutant is with anti-pollution mechanical seal device, including rotating ring 1, quiet ring 2 and quiet ring holder 3, quiet ring 2 with by being provided with abrasive dust collection ring 4 between the sealed axle, form the cavity 5 that is used for depositing the abrasive dust between the surface of this abrasive dust collection ring 4 and the quiet ring 2 inner wall. And abrasive dust generated by friction pairs of the moving ring 1 and the static ring 2 and normally leaked lubricating liquid fall into the cavity 5 in the operation process of the reaction kettle. A suction channel 6 is arranged in the stationary ring seat 3, the inner end of the suction channel 6 is communicated with the cavity 5, and the outer end of the suction channel 6 is connected with a vacuum suction device. The vacuum suction device is started to timely clean the abrasive dust and the lubricating liquid in the cavity 5, and the abrasive dust and the lubricating liquid in the cavity 5 are prevented from entering the reaction kettle due to excessive accumulation, so that the cavity 5 can be cleaned on line at regular time without disassembling equipment, and the field maintenance workload is greatly reduced.
Referring to fig. 1, the vacuum suction device comprises a pipeline 7 and a movable vacuum suction machine 9, wherein the inner end of the pipeline 7 is connected with the outer port of a suction channel 6, the outer end of the pipeline is connected with the vacuum suction machine 9, and a normally closed valve 8 and an observation mirror 10 are arranged on the pipeline 7. Normally closed valve 8 is closed when reation kettle normally works, operates a period, when reation kettle normally shuts down, can clear up the pollutant, and its flow is: the normally closed valve 8 is opened first, and the movable vacuum suction machine 9 is started to clean the pollutants in the cavity 5. Whether the pollutants are cleaned up or not is observed through the observation sight glass 10 in the cleaning process. After cleaning, the normally closed valve 8 is closed, and the reaction kettle can enter a working state. The whole process is convenient and efficient, and any equipment does not need to be disassembled. Can carry out the pollutant clearance operation to many reation kettle through a portable vacuum suction machine 9, be favorable to practicing thrift equipment cost.
The above description is only used for illustrating some principles of the anti-pollution mechanical sealing device for the kettle capable of cleaning the pollutants on line, but not to limit the present invention to the specific structure and application range shown and described, so all the corresponding modifications and equivalents that may be utilized all belong to the patent scope applied by the present invention.
