Description

Chemical dispenser of water purification equipment {DISINFECTANT DROPPING APPARATUS FOR CLEAN WATER SYSTEM}

The present invention relates to a chemical dispenser of water purification equipment, to a simple type water purifier to purify the drinking water by drinking disinfecting chemicals stored in a simple water storage tank, a chemical dispenser of a water purification equipment used for water purification tanks.

Generally, the water storage tank is divided into shapes such as a rectangle and a cylinder, and is divided into concrete, resin material, and stainless material according to panel assembly type, masonry type, unit stack type, and materials used.

These water storage tanks come in various shapes and sizes, taking into account their economic feasibility along with their storage capacity, size, use and use.

In particular, the water storage tank used as a water purifier additionally includes a disinfectant dispensing device such as a chemical injector or a chlorine injector.

In the disinfectant dispensing device according to the prior art, a vacuum self-contained chlorine injector that directly attaches to a chlorine container valve to inject chlorine gas, and a solid chlorine injector of a water tank that injects solid chlorine directly into a water tank (Registration Utility Model No. 20) -263574).

Regardless of how they are used, they aim to mix disinfectants such as chlorine into the water in the water storage tank, but they do not have real-time insight into their operating conditions from remote locations.

In addition, the conventional technology has a disadvantage in that it is very inconvenient to use in farming and fishing villages or livestock sites because an independent power source is not used to perform computer control for chlorine residual amount control.

In addition, the majority of chlorine injector is controlled by the method of injecting solid chlorine according to the time control, there is a disadvantage that it is difficult to perform precise chlorine input control.

In addition, in the case of the prior art solid chlorine injector, when the rotating plate rotates, the solid chlorine seated in the transport hole of the rotating plate rotates, and makes direct contact with the solid chlorine which is located at the lowest of the extra solid chlorine filled in all the loading pipes. By doing so, the solid chlorine is in contact with each other for a long time there is a fear that the debris from the solid chlorine acts as an obstacle to the rotation of the rotating plate, leading to unstable operation such as operation stop.

In addition, the solid chlorine injector of the prior art has a frictional force between the solid chlorine in the transport hole and the solid chlorine in all other load pipes as the rotary plate rotates, causing frequent motor failure, as well as vibration and noise. There is a big disadvantage.

In addition, the conventional solid chlorine injector is equipped with a consumption detection sensor at the bottom of each loading tube, so if the actual solid chlorine has exited the loading tube but a failure occurs in the transport hole of the rotating plate, the water tank It is possible to misjudge whether or not the solid chlorine is actually added in real time, and there is a disadvantage in that a precise input process cannot be performed.

In addition, the conventional disinfectant dispensing device has a disadvantage that if the failure of the device or the drug inventory, the remote administrator can not immediately know this, difficult to maintain and maintain.

In addition, the disinfectant dispensing device currently used in domestic simple water purification plant is not elaborate in its operation, most of them have only a function that is operated by simply setting the time.

In addition, due to the structure of the chemical injector, the disinfectant is weakened due to moisture and is not properly input.

As a result, most of the users who drink the constant water in drinking water are drinking water that has not been disinfected.

In addition, if the disinfectant is injected regardless of the water level, the discomfort due to the very strong smell of disinfectant when drinking, it causes a harmful effect on health.

Therefore, the object of the present invention is to operate in a limited manner in accordance with the electronic control signal of the main controller, it is possible to minimize the moisture penetration to the medicine loaded in the medicine container, it is possible to accurately input the medicine without damage to the medicine, It is to provide a chemical dispenser of water purification equipment that is simple and has no trouble.

In the present invention, the shaft length of the medicine cabinets 111 to 114 and the number of the medicine cabinets 111 to 114 embedded in the pill cartridge 110 may be changed or changed in a minute configuration such as the number of the position sensors 105 to 109, the motor control algorithm, and the shaft length of the operating shaft. Of course, it can be developed as a large-capacity drug injector that can easily put more than 100 pills.

In the following, it will be described for the coupling relationship and the operating relationship of the chemical input device of the water purification equipment of the present invention as described in detail above.

3 and 4, the lower end of the drug input passage 162 in the drug injector of the present invention is inserted in accordance with the through hole 152 of the lower plate 150, and penetrates the drug injection passage 162 The lower portion of the body housing 100 except for the hole 152 is sealed with a lower plate 150 fastened by fixing bolts.

The chemical injection passage 162 penetrates the inclined lower portion 103 at one end of the sliding groove 102, and when the operating shaft 130 is reciprocated in the sliding groove 102, the pills 170 are individually. Can be dropped to the bottom of the medicine dispenser.

The manager opens the cover 116 and the stopper 115 of the pill cartridge 110, and then fills each of the medicine containers 111 to 114 with the prepared disinfectant tablets 170, and again the stopper 115 and the cover. Seal 116.

Thereafter, the control wire 180 is electrically connected to the main controller 190. At this time, the control wire 180 is a motor connection wire for interconnecting the motor 144 to the motor control circuit, the light emitting unit 160 and the light receiving unit 161 of the drop sensor and the first to fifth position sensors 105 to Each of the wires for sensor connection interconnecting 109 to a sensor interface.

Then, the manager is fixed to the chemical injection device of the present invention in the installation position where the chemical injection hole is formed in the upper surface of the water storage tank 10, which is a water purification equipment.

At this time, the manager matches the chemical input passage 162 of the body housing 100 to the chemical input hole of the water storage tank, and then, using the fixing edge 101 of the body housing 100, the water storage tank 10 It may be fixed by bolts on the upper surface, or fastened by a sliding coupling method to the binding groove at the installation position and then fixed by screwing.

Of course, the solar cell 191 is also connected to the main controller 190, and collects sunlight to charge the battery of the main controller 190.

After the battery is charged in this way, the administrator turns on the power of the main controller 190, turns off the operation start switch, and enters the setting mode, and then the pill cartridge 110 according to the guide text displayed on the LCD display element. Input the tablet number and the set value such as the system initial value and STD-HEIGHT. In this case, the main control circuit of the main controller 190 receives the set value and checks the current power supply and the current water level.

After that, when the administrator changes the operation mode by turning on the operation start switch, the chemical input device of the water purification equipment of the present invention is set in the setting mode, that is, one of time mode, flow rate mode and mixed mode. In accordance with the tablet 170 is an operating state that can be injected into the water storage tank (10).

The light emitting unit 160 and the light receiving unit 161 of the drop sensor do not detect the pills and transmit the non-injection signal to the main control circuit through the sensor interface.

The first position sensor 105 detects the front end of the operating shaft 130 and transmits a contact signal to the main control circuit in the same manner as described above, and the remaining second, third, fourth, and fifth position sensors 106-. 109 transmits a non-contact signal to the main control circuit.

When the administrator sets the setting mode of the main controller to the time interval mode, the microprocessor of the main control circuit calculates the pill input time in proportion to the value input through the water level sensor installed in the water storage tank, and then calculates the calculated value. The motor control circuit transmits power and a control signal to the motor 144 correspondingly.

The motor 144 rotates the rotating shaft according to the transmitted power and the control signal, and according to the gear coupling relationship between the worm gear 141 coupled to the rotating shaft and the rack gear 131 of the operating shaft 130, the operating shaft 130. Reciprocally transfers the first, second, third and fourth transfer sections (a, b, c, d) having different stroke distances in sequence.

That is, when the motor 144 rotates the worm gear 141 in the counterclockwise direction, while the operating shaft 130 is moved backward, the first position sensor 105 does not detect the front end of the operating shaft 130. Send the contact signal to the main control circuit.

Thereafter, the rear end of the operating shaft 130 arriving at the last position of the first transfer section a is sensed by the second position sensor 106, and the second position sensor 106 transmits a contact signal to the main control circuit. do.

In response, the motor control circuit of the main control circuit stops the motor 144 and rotates the worm gear 141 clockwise again. At this moment, the operating shaft 130 is in a position to open the lower end of the first medicine 111, the lower end of the second, third, fourth medicine (112, 113, 114), the first medicine Since the lower end of the 111 is opened, the pills 170 loaded in the first medicine container 111 are moved downward by their own weight, and one of the lowest pills is sliding having a depth corresponding to the thickness of the medicine 170. It is placed in the groove 102 and the other pills are stacked on top of the injected pills.

Accordingly, the working shaft 130 is moved forward from the last position of the first transfer section (a) to the original initial position, while pushing out one of the pills injected into the sliding groove 102 toward the inclined lower portion 103, The lower ends of the first, second, third, and fourth medicine containers 111, 112, 113, and 114 are sealed. The one pill that is pushed out is slid from the inclined bottom 103 and freely falls into the chemical inlet passage 162 and is introduced into the water storage tank 10 at the same time.

The drop sensor detects a pill that passes between the light emitting unit 160 and the light receiving unit 161, and transmits an input signal to the main control circuit, and the main control circuit calculates a value obtained by subtracting a number from the medicine stock, This is transmitted to the receiver through the RF module, and the receiver reduces the medicine inventory displayed on the 7-segment by one corresponding to the received value, so that the administrator confirms that a pill has been injected.

However, even though the operating shaft 130 reciprocates the first transfer section a normally, the pills are not detected at the light emitting unit 160 and the light receiving unit 161 of the drop sensor, and the operation of the motor 144 is abnormal. If the motor's rotary shaft does not rotate due to weak rotation and the load is applied to the power applied to the motor, the RF module of the main control circuit receives the power for a finite time interval, and periodically transmits the weak transmission data. Transmitting to the receiver, the motor control circuit interrupts the power supplied to the motor 144 of the medicine dispenser.

On the other hand, the operating shaft 130 is the inside of the water storage tank 10 all the pills 170 of the first medicine container 111 while repeatedly reciprocating the first transfer section (a) in accordance with the control signal of the motor control circuit. Put it in.

Thereafter, even when none of the pills 170 of the first medicine container 111 are put into the water storage tank 10, the working shaft 130 reciprocates the first transfer section a.

However, even though the operating shaft 130 reciprocates the first transfer section a normally, the pills are not detected at the light emitting unit 160 and the light receiving unit 161 of the drop sensor, and the operation of the motor 144 is normally performed. When operated, the motor control circuit controls the rotation direction and the power supply time of the motor 144 to cause the operating shaft 130 to reciprocate the second transfer section b.

That is, the motor 144 receives the power and the control signal from the motor control circuit and rotates the rotary shaft returned to the initial position in the counterclockwise direction. As a result, the operating shaft 130 is moved backward, and thus, the first position sensor 105 is rotated. The non-contact signal that does not detect the front end of the operating shaft 130 is transmitted to the main control circuit.

The rear end of the operating shaft 130 arriving at the last position of the first transfer section (a) is detected by the second position sensor 106, so that the second position sensor 106 transmits a contact signal to the main control circuit. However, the motor control circuit of the main control circuit continues to rotate the worm gear 141 in the counterclockwise direction without stopping the motor 144.

Thereafter, the rear end of the operating shaft 130 arriving at the last position of the second transfer section b is sensed by the third position sensor 107, and accordingly the third position sensor 107 transmits a contact signal to the sensor interface. The motor control circuit of the main control circuit responds to the main control circuit and stops the motor 144 and rotates the worm gear 141 clockwise again.

Also, at this moment, the operating shaft 130 opens the second medicine container 112 loaded with the lower and second tablets of the first medicine medicine 111, which is an empty container, but the third medicine medicine 113 and the fourth medicine medicine 114 The bottom of) is still in the closed position.

In addition, since the lower end of the second medicine container 112 is opened, the pills loaded in the second medicine medicine 112 are moved downward by their own weight, and one tablet is put into the sliding groove 102 and the other pills are loaded. Piled up.

Accordingly, the operating shaft 130 is moved forward from the last position of the second transfer section (b) to the original initial position, while pushing out one of the pills injected into the sliding groove 102 toward the inclined lower portion 103, The lower ends of the first, second, third, and fourth medicine containers 111, 112, 113, and 114 are all sealed. The one pill that is pushed out is slid from the inclined bottom 103 and freely falls into the chemical inlet passage 162 and is introduced into the water storage tank 10 at the same time.

As the operation of the motor 144 is controlled in the same manner, the operation shaft 130 reciprocates the third transfer section c and the fourth transfer section d sequentially and repeatedly. All the pills loaded in the fourth medicine containers 113 and 114 are introduced into the water storage tank 10.

Then, when the pill stock is 5 or less, the RF module of the main control circuit is supplied with power for a finite time interval, and periodically transmits the weakly-transmitted transmission data to the receiver, and the motor control circuit is supplied to the motor 144 of the medicine dispenser. Interrupt the supplied power.

As described above, the chemical dispenser of the water purification equipment according to the present invention, while performing the monitoring in real time through the main controller and the receiver, injecting the disinfecting chemicals to the water purification equipment individually corresponding to the various operation setting mode set in the main controller As a result, it is advantageous for an administrator to grasp the operating state of the drug injector in real time at a receiver remote from the main controller.

In addition, the medicine dispenser of the water purification equipment according to the present invention is all the bottom of the body housing except the pill input passage, and the top of the medicine container installed in the pill cartridge is sealed with a cap and a cover at the same time, one medicine container is empty Since the operating shaft does not open the bottom of the remaining medicine cabinet until it is lost, there is a very good moisture protection effect.

In addition, the chemical dispenser of the water purification equipment according to the present invention is operated by its own independent power source (battery) charged with a solar cell connected to the main controller, there is an advantage that can be applied to the water purification equipment installed in the back country, wallpaper.
