Vacuum pump liquid blocking filter device

This creation relates to a filter device; more particularly, to a filter device that blocks liquid from entering a vacuum pump.

The application field of vacuum pump is very diverse. There is a filter device in front of the vacuum pump. The vacuum pump filter device is an important component of the vacuum pump. The daily maintenance of the vacuum pump filter device is directly related to the length of use of the vacuum pump. Therefore, the vacuum pump must be done in daily use. Maintenance of the filter unit.

During the operation of the vacuum pump, the extracted gas must be doped with some impurity particles. These particles have particles generated by friction, and there are impurities left in the parts that are not cleaned, and there are also early oxidatively deteriorated particles generated by high temperature in some places. There are iron filings, sand particles, rubber particles, etc., mixing into the vacuum pump will cause internal components to wear, damage and burn tiles, reducing service life and reliability, so it needs to be protected and effectively filtered by vacuum pump filter device.

Most of the technical improvements pursued by vacuum pump filtration devices today tend to improve the vacuum extraction efficiency and the filtration of impurities in the gas. However, when vacuum extraction is performed, if the liquid is inhaled into the vacuum pump, then the airtight oil to the vacuum pump Mixed emulsification and internal components form water loss, which will greatly affect the extraction efficiency, and even directly cause the vacuum pump to fail. Later, many maintenance time costs will be invested.

In view of this, the creators of this case have been engaged in research and development experience in related fields for many years, and have conducted in-depth discussions on the above-mentioned shortcomings, and actively sought solutions according to the above-mentioned needs. After a long period of hard work and repeated tests, this is finally completed. creation.

The first object of the present invention is to provide a filtering device that blocks liquid from entering a vacuum pump.

In order to achieve the above object, the liquid-repellent filtering device of the vacuum pump of the present invention mainly comprises a filter bottle and a filter core, which can be installed on the vacuum pump:

The filter bottle comprises a filter bottle cover and a collection bottle, wherein the filter bottle cover is provided with a filter bottle cover outer locking portion and a filter bottle cover inner locking portion, and the filter bottle cover is provided with an air inlet portion at both ends thereof In the air outlet portion, the collection bottle is provided with a collection bottle lock portion, and the collection bottle lock portion is interlocked with the outer lock portion of the filter bottle cover.

The filter core includes a filter core cover, a filter core tube, a filter material and a floating body disposed inside the collection bottle, and the filter core cover is provided with a filter core cover locking portion, and the filter core cover locking portion is The locking portion of the filter bottle cover is interlocked with each other, and the filter cover is internally provided with a filter cover locking portion and a gas passage connecting the inside of the filter bottle cover, and the wall of the filter tube is hollowed out, the filter One end of the heart tube is provided with a filter tube locking portion, the filter tube locking portion is interlocked with the filter core locking portion, and the other end of the filter tube is provided with a grip portion, and the filter material is sleeved on the Outside the filter tube, the floating body is installed inside the filter tube.

In the vacuum extraction operation, the filter material will filter out the dust and impurities in the gas, and the gas to be extracted, in addition to the gas, will be mixed with liquid, in order to prevent the emulsification caused by the mixing of the liquid and the airtight oil or the internal components of the vacuum pump. The water loss affects the normal operation of the vacuum pump and even direct failure. Therefore, in this creation, a floating body is specially provided inside the filter tube. As long as the vacuum extraction is continued, the extracted liquid will accumulate in the collection bottle little by little. When the liquid volume accumulates inside the collection bottle until the filter material can be flooded, the liquid will pass through the filter material and enter the filter tube from the hollow filter tube wall. After the floating body contacts the liquid, it will naturally be due to the buoyancy of the liquid. The track of the filter tube is gradually displaced upward, and the float can be smooth regardless of whether it is hollow or closed. The float floats, and one end of the float is made to have a cone-like angle, and the cone angle is about 60 to 150 degrees. Finally, the floating body can completely block the gas passage port, and the pressure displayed by the vacuum gauge is lowered. The user knows that the collection bottle is full of liquid and needs to be cleaned.

The second object of the present invention is to provide a filtering device that can easily lock the filter tube.

In order to achieve the above object, in the liquid-repellent filtering device of the vacuum pump of the present invention, when the user wants to disassemble the filter core for replacement cleaning, the user can grasp the grip portion by hand, and rotate the grip portion to rotate the filter tube from the filter core cover. Separate, if you don't use your hand, you can also put the lock tool into the receiving groove at the bottom of the grip. It will be more convenient in the process of loading and unloading the filter tube. After removing it, the user can consider the use of the filter material. The dirt can be further replaced and replaced with a new filter to ensure the quality of the filtration.

The third object of the present invention is to provide a filtering device that allows a gas to flow smoothly through the filter material into the inside of the filter tube to form a stable air flow without causing the floating body to shake.

In order to achieve the above object, the liquid-repellent filtering device of the vacuum pump of the present invention can be provided with a sealing member at the upper end of the filter cover locking portion, the gas passage opening and the upper and lower ends of the filter material, so that the gas is not easily removed from each The gap at the joint of the component enters the inside of the filter tube, so that the floating body does not sway due to the disturbance of the entering turbulent airflow, so that the gas smoothly passes through the filter material into the inside of the filter tube, and the position of the floating body can be kept unchanged. When the floating body is displaced upward inside the filter tube, the gas passage opening can be aligned, and no gap is generated for the liquid to pass, so that the filtering device can effectively function.

Finally, please refer to Figure 5A, Figure 5B and Figure 5C, and refer to Figure 1; as can be seen from the figure, when cleaning the filter device, the user should grab the collection bottle (11) and collect the bottle. (11) Unscrew and separate from the filter bottle cap (10), then pour off the liquid in the collection bottle (11), clean the collection bottle (11), and then remove the filter (2), the user can Grab the grip portion (211), and rotate the grip portion (211) to unscrew the filter tube (21) from the filter core cover (20). If the hand is not used, the lock tool can also be placed into the grip portion (211). The bottom receiving groove (2110) is more convenient in the process of loading and unloading the filter tube (21). After the removal, the user can consider replacing the filter material (22) and replacing it with a new filter material (22) to ensure filtration. Quality, and then clean the filter tube (21) and the floating body (23). After cleaning the creation, put the floating body (23) back into the filter tube (21) and install the filter material (22). ), the filter tube (21) and the filter cover (20) can be locked by hand or a locking tool, and finally the collection bottle (11) and the filter bottle cover (10) are locked to each other, and can be used continuously.

In summary, the liquid-repellent filtering device of the vacuum pump of the present invention has the following advantages:

1. The liquid-repellent filtering device of the vacuum pump of the present invention can block the liquid from entering the vacuum pump by using the floating body, thereby avoiding the normal operation after the liquid enters the vacuum pump, resulting in a decrease in extraction efficiency or a failure of the vacuum pump.
