Description

Dental air cleaner {Dental air cleaner}

The present invention relates to a dental air purifying apparatus, and more particularly, by connecting a plurality of towers filled with different adsorbents in series and adsorbing and desorbing moisture and other foreign matter from the compressed air through the adsorbents when the compressor is operating. The present invention relates to a dental air purifier capable of continuously supplying high purity dry air.

In general, dental medical equipment is provided with an air compression device that checks the condition of the teeth or gums during the treatment of the patient's teeth or injects compressed air into the patient's mouth for cleaning the teeth. The air compressor is connected to the compressor to suck the compressed air generated by the compressor, and supply the sucked compressed air to a unit chair, which is a dental medical device, to spray into the oral cavity of the patient.

However, in such an air compressor, moisture is present in the compressed air generated by the compressor. As a result, the microorganisms such as bacteria multiply due to this water, and the patient may be infected with the bacteria. There was a problem that dust, such as can be introduced into the oral cavity of the patient in a state adsorbed in water.

In addition, when the compressed air containing such water or oil is blown to the affected part, there is a pulsation that greatly reduces the treatment efficiency of the tooth by lowering the adhesive strength when the implant is attached to the tooth.

A conventional dental air dryer for solving this problem is disclosed in detail in Korean Patent Publication No. 306575.

Looking at this, the conventional dental air dryer (2) is provided with a storage tank (30) for dehumidifying and storing compressed air supplied from the compressor (100), and the compressor (100) on one side of the storage tank (30). Connected to the first solenoid valve 12 and the first solenoid valve 12 to dehumidify the moisture in the compressed air and supply the same to the storage tank 30, and at least one of the plurality of storage tanks 30 is provided at one side. And the dehumidifiers 18 and 20 connected by the regeneration device 50, the discharge pipe 32 provided to supply the compressed air stored at one side of the storage tank 30 to the medical device 110, and the storage tank 30. It is provided on one side of) comprises a control unit 80 for controlling the operation of the air dryer (2).

The dehumidifier (18, 20) and the storage tank 30 is connected in communication via the storage pipes (24, 24a, 24b), one side of the storage pipes (24, 24a, 24b) by the pressure difference in the direction of the pipe line The shuttle valve 26 and the check valve 28 for preventing a backflow are provided so as to switch.

The regeneration device 50 is connected to the connection pipe 52 is installed to one side of the dehumidifier (18, 20) provided with at least a plurality of dehumidifier (18, 20), and the control pipe (80) in the connection pipe (52) Compressed air is provided on one side of the second solenoid valve 54 and the connection pipe 52 spaced apart from the second solenoid valve 54 so as to interlock with the first solenoid valve 12 for a predetermined time. An orifice 56 is provided for discharging under pressure.

One side of the discharge tube 32 is provided with a filter 34 to remove foreign substances in the compressed air discharged from the storage tank 30, one side of the discharge tube 32 is compressed air passing through the filter 34 Is provided with a heater 36 for heating to a predetermined temperature to supply to the medical device 110, the heater 36, the temperature sensor 40 for measuring the temperature inside the heater 36, and a medical device ( A temperature sensor 42 for measuring the temperature of the compressed air supplied to the 110 is provided.

Referring to the operation of the conventional dental air dryer configured as described above, the operation time of the first solenoid valve 12 to the control unit 80 provided in the air dryer 2 at the time of initial installation of the air dryer 2 (10) Minute), the operating time (30 seconds) of the second solenoid valve 54, and the temperature (20 ??-35 ??) of the heater 36, etc., are preset. When the air dryer 2 is operated, the compressed air from the compressor 100 flows into the first solenoid valve 12 through the suction pipe 10 and is compressed by the first solenoid valve 12. Air is introduced into the first dehumidifier 18 on one side through the first supply pipe 14. As described above, the compressed air introduced into the first dehumidifier 18 is dehumidified by adsorption of moisture in the compressed air by the adsorbent 22 of the first dehumidifier 18, and the dehumidified compressed air is stored in the storage tube 24a. Inflow to the storage tank 30 is passed through the shuttle valve 26 and the check valve 28. In this case, when the storage device 30 and the medical device 110 connected through the discharge pipe 32 are operated, the compressed air stored in the storage tank 30 flows into the discharge pipe 32 to allow the medical device 110 to operate. Bar is supplied to the side, at this time the foreign matter in the compressed air is filtered by the filter 34 provided on one side of the discharge pipe 32 is heated to a predetermined temperature by the heater 36 to the medical device ( Through 110) into the oral cavity of the patient. On the other hand, after the air dryer 2 performs the above-described operation for a predetermined time (10 minutes), the controller 80 controls the operation of the first solenoid valve 12 to switch the pipeline. Then, the first supply pipe 14 and the suction pipe 10 of the first dehumidifier 18 is closed and the first supply pipe 14 is in communication with the first discharge pipe 14a.

In addition, the second supply pipe 16 of the second dehumidifier 20 is in communication with the suction pipe 10 and the conduit with the second discharge pipe 16a is closed. Therefore, the compressed air supplied from the compressor 100 is introduced into the second dehumidifier 20 through the second supply pipe 16 by the first solenoid valve 12 to dehumidify the moisture in the compressed air. At this time, when the first solenoid valve 12 is operated by the control unit 80, the second solenoid valve 54 is operated to open the conduit of the connection pipe 52. Accordingly, the compressed air introduced into the second dehumidifier 20 as described above passes through the second solenoid valve 54 at a predetermined pressure (8 kg / cm 2) by the orifice 56 of the connecting pipe 52. In addition to being injected toward the dehumidifier 18, a part of the compressed air remaining in the connection pipe 52 by the small diameter of the orifice 56 is introduced into the storage pipe 24b to the predetermined pressure to the shuttle valve 26 It acts as to open the pipeline to be introduced into the storage tank (30). As described above, moisture contained in the first dehumidifier 18 by the compressed air injected into the first dehumidifier 18 at a predetermined pressure flows into the first supply pipe 14 and is discharged through the first solenoid valve 12. 1 is discharged to the discharge pipe (14a). Therefore, the first dehumidifier 18 in which water is discharged and dried as described above is in a reusable state.

On the other hand, in the above operation, after a predetermined time (30 seconds), the control unit 80 controls the second solenoid valve 54 to close the conduit of the connecting pipe 52 to stop the operation of the regeneration device 50. Let's go. Therefore, the compressed air dehumidified by the second dehumidifier 20 as described above continues to flow into the storage tank 30 through the shuttle valve 26 and the check valve 28, and is stored therein. In use, dehumidified compressed air in the storage tank 30 is filtered through the filter 34 and the heater 36 as described above, and is injected into the oral cavity of the patient as compressed air of warm air.

However, the conventional dental air dryer operated as described above has a structure in which a dehumidifier is connected in parallel, and since a separate regeneration device is provided, not only the structure is complicated but also the manufacturing cost is high.

In addition, the conventional dental air dryer has a problem that when the compressor is stopped, the compressed air remaining after use is left in the storage tank as it is, and moisture is generated in the storage tank when it is maintained for a long time so that bacteria and the like grow.

The present invention was devised to solve the above problems, by connecting a plurality of towers filled with different adsorbents in series and using the adsorbents to adsorb and desorb water and other foreign matter from the compressed air to dry ultra-high purity In addition to supplying air continuously, when the compressor is stopped, the compressed air remaining in the storage tank can be fed back naturally and the amount can be controlled to prevent the generation of moisture in the storage tank to suppress the growth of bacteria and fundamentally eliminate odors. It is an object of the present invention to provide an adsorption regenerative air purifying apparatus.

Hereinafter, with reference to the accompanying drawings illustrating a preferred embodiment of the dental air purification apparatus according to the present invention in detail.

Accompanying drawings Figure 2 is a perspective view showing the configuration of the dental air purifying apparatus according to the present invention, Figure 3 is an exploded view showing the operation of the dental air purifier according to the present invention and the flow of compressed air sequentially.

Dental air purifying apparatus 200 of the present invention is a device for supplying to the unit chair (not shown) to maintain the compressed air generated by the compressor 210 at a constant pressure, flow rate and purity, inside the case 201 A plurality of dehumidifying towers 220 and 230 are provided, and each tower 220 and 230 is filled with different adsorbents so that the compressed air is connected in series circulation along a conduit 202 connected therebetween. It is provided as a structure.

In addition, the plurality of towers are divided into a first tower 220 and a second tower 230, the compressed air carried from the compressor 210 outside the case 201 at the inlet side of the first tower 220. An oil remover 250 configured to remove oil components therefrom while temporarily storing it and a radiator 240 for cooling the supplied high-temperature and high-pressure compressed air to an appropriate temperature are sequentially provided from the compressor 210. As shown in FIG. 1, the compressor 210, the oil remover 250, the radiator 240, and the first tower 220 are connected to each other through an inlet pipe 203.

Reference numeral "221", which is not described in FIG. 2, is a means for collecting and discharging water. When the tank pressure reaches an appropriate pressure range and the compressor is stopped, the water droplet generated during the dehumidification process of the first tower is discharged to the outside. It is preferable that the structure is made in the form of a conventional valve.

The plurality of towers 220 and 230 may optionally include silica gel, alumina (abbreviated as 'A'), and molecular sieves (abbreviated as 'M'). In an embodiment of the present invention, a first tower 220 filled with alumina (A) and a second tower 230 filled with Morecure Sieves (M) are provided. The alumina (A) filled in the first tower 220 is preferably used in the form of a round granule having a relatively high absorption rate compared to the Molecular Sheaves (M).

A check valve 260 is provided on the outlet side conduit 204 extending from the outlet side of the second tower 230 to prevent backflow of compressed air dehumidified through the first and second towers 220 and 230. Is provided, the outlet side duct 204 passing through the check valve 260 is drawn out of the case 201 is connected to the storage tank 270 for storing the dehumidified compressed air. Compressor 210 and the storage tank 270 is preferably provided in a structure combined integrally for easy installation and maintenance.

At the outlet side of the check valve 260, preferably at the outlet side of the outlet side conduit 204, high-pressure compressed air remaining in the storage tank 270 when the air purifier 200 is stopped is fed back. The feedback conduit 205 is drawn out, and the other end of the feedback conduit 205 is connected to the inlet side of the check valve 260 again. In addition, a control valve 280 (also referred to as a 'speed control valve') is provided on the feedback conduit 205 to adjust the flow rate and flow rate of the compressed air to be fed back. Opening and closing the flow path in a manner to achieve a structure to adjust the water flow of the feedback pipe 205. Meanwhile, in the present invention, a configuration including all of the feedback conduit 205, the check valve 260, and the control valve 280 will be referred to collectively as a 'purge unit'.

The dental air purifier 200 of the present invention configured as described above is supplied with compressed air generated when the compressor 210 is operated into the case 201 through the inlet pipe 203 and introduced into the oil remover 250. do. At this time, in the compressed air introduced into the oil remover 250, the vortices are generated, and the oil component in the compressed air is separated and exits to the other side of the oil remover 250 in the air state.

Meanwhile, the compressed air supplied from the compressor 210 is maintained at a high temperature and a high pressure, so that the compressed air is cooled to an appropriate temperature in order to increase the drying efficiency of the compressed air introduced into the first and second towers 220 and 230. There is a need. To this end, the compressed air passing through the oil remover 250 is adjusted to an appropriate temperature level while passing through the radiator 240, and then flows into the second tower 230 through the first tower 220.

In this process, the alumina (A) filled in the first tower 220 absorbs moisture contained in the compressed air first, and then, after the inside of the second tower (230), the Molecular Sieves (M) is filled. The secondary air absorbs the moisture that is not completely removed in the compressed air while providing compressed air in a completely dried state. The compressed air completely dried through the first and second towers 220 and 230 passes through the check valve 260 along the outlet side conduit 204 and then is drawn out of the case 201 to be stored outside the storage tank 270. Stored within).

The flow of compressed air described above is shown by an arrow (??) in FIG.

On the other hand, the compressed air stored in the storage tank 270 is supplied to a unit chair (not shown) for treating the patient's teeth, and the cycle is terminated every time the operation of the compressor 210 is stopped or the limit pressure is reached during continuous use. When the operation is interrupted, the compressed air in the tower 1,2 is instantaneously released through the water collecting and discharging means 221 of FIG. 2, at which time the water is also forced out. In addition, the compressed air remaining in the storage tank 270 is fed back along the outlet side conduit 204 in the direction of the arrow (...>) shown in Figure 3 due to the pressure difference inside and outside. At this time, the fed back compressed air does not pass through the check valve 260, and naturally circulates while returning to the inflow side of the check valve 260 through the feedback pipe 205, the compressed air fed back from the storage tank 270 The flow rate and flow rate of the control is adjusted according to the opening and closing degree of the control valve (280). That is, when the compressor 210 is stopped, water is first discharged through high pressure discharge and secondly, gradually dried with dry air produced in the storage tank 270 to completely regenerate the tower 220 (230).

As described above, the dental air purifying apparatus of the present invention adsorbs and desorbs water and other foreign matters from the compressed air by using an adsorbent packed in each tower while passing through a plurality of towers connected in series when the compressor is operated. It is possible to supply ultra-pure clean compressed air continuously.When the compressor is stopped, the compressed air remaining in the storage tank is naturally fed back by the pressure difference between inside and outside, and the compressor is restarted when the pressure falls below a certain pressure. By continuously producing new compressed air, it is possible to prevent the generation of moisture in the storage tank to suppress the growth of bacteria and fundamentally solve the problem of odor generation. In addition, since the feedback amount can be adjusted variably, the user's demand can be actively coped with.

As such, the dental air purifying apparatus of the present invention can be manufactured in a small size due to its simple configuration, and the installation area can be solved when using the indoor space.

In addition, the dental air purifier of the present invention forcibly discharges compressed air in the tower when the compressor is stopped, and discharges the filtered water from the water collecting and discharging means at the bottom of the first tower specially designed for water removal. Then, by allowing the compressed air remaining in the storage tank to be naturally fed back to prevent the generation of moisture in the storage tank to suppress the growth of bacteria, it is possible to fundamentally solve the problem of odor generation.

In addition, it is possible not only to maintain a constant pressure, flow rate and purity even when the compressor is restarted, but also to maintain a constant performance regardless of the season, and to reduce the air consumption by more than 30% compared to the conventional apparatus, thus operating the compressor. The reduction makes it possible to extend the life of the compressor.
