Description

Automated metered dose injector {omitted}

The present invention is a device for sterilizing and disinfecting raw water from tap water or simple tap water. Until now, calcium hypochlorite, which is a solid chlorine, has been mainly used. However, calcium hypochlorite takes a long time to dissolve in water. In addition, it has strong corrosiveness, and recently, sodium chlorite, which is liquid chlorine, has been used a lot. However, the sodium hypochlorite dissolves quickly in water and does not generate residual suspended matter. Is generated, and the remaining crystals of sodium are formed, and scale and crystals are generated in the metering pump to inject chemicals using check valves, which causes the failure.

Thus, the present invention is designed to prevent the accumulation of scale or crystals by rotating the valve acting as a check valve so that chemicals can be injected without being affected by the scale or crystals.

The drive in this paper (11) rotates the feed shaft by the rotational force of the power and non-powered drive. The feed shaft includes (1) the inlet and (5) the piston (6) the reciprocating shaft (8) the reciprocating spring (10). ) Install the lake opening and closing ring to rotate together, and install (2) suction opening (3) discharge port (7) flow control screw (12) lake opening and closing shaft (13) lake pressing rod (14) lake opening and closing shaft spring. Does not rotate, the lake opening and closing shaft and the lake presser can reciprocate, the reciprocating shaft is 1/2 high and 1/2 low (this car is the maximum reciprocating distance of the piston), and four holes are made between them. (4) Place the reciprocating spring on the side and allow it to be pushed out by the spring and pushed in by the flow adjusting screw.The flow adjusting screw turns out to the left and goes in to the right. The part where it meets the axis puts the ball so that it doesn't load

(1) The inlet is rotated in close contact with the inlet and (3) the outlet. (5) The piston is inhaled from the inlet when the piston is inhaled while reciprocating by (6) the reciprocating shaft. When the piston was pushed out and rotated, the inlet contacted the outlet and pushed the chemical into the outlet to inject the chemical.

In order to prevent minute backflow, the lake presser was opened and blocked in the lake, which is the chemical transport pipe, and the suction port side was opened, the discharge port side was closed, and the discharge port side was opened, and the discharge port side was closed. In the city, one of the two places is closed, so that the medicine can be injected safely without minute backflow.

The amount of chemical input is controlled by the flow adjusting screw. When the flow adjusting screw is turned to the right, the reciprocating distance of the reciprocating shaft is lengthened by turning inward and the reciprocating distance of the reciprocating shaft is shortened by turning it to the left to adjust the reciprocating distance of the reciprocating shaft. Can adjust the amount of chemical

When no power is used, it is a non-powered driving device (18) to install the impeller by using the flow of raw water in the water pipe to obtain the rotation. (18) The impeller is rotated by the flow of raw water in the water pipe so that the amount of chemical injection (18) The speed of impeller rotation is proportional to the flow rate of raw water in the water pipe, so that accurate chemicals can be injected in a fixed amount.

When using motor rotation, install an encoder that detects the rotation of the motor by detecting the rotation of the motor (22) and send a signal to the controller (22) The controller controls the rotational speed of the motor as required (18) Install the flow meter in the water pipe (19) The flow meter (19) In the flow meter (20) The flow sensor senses the flow of raw water in the water pipe (18) and sends the signal to the controller (22). (18) When the amount of raw water in the water pipe flows a lot, increase the number of revolutions of the motor. (18) When the flow of raw water in the water pipe flows less, reduce the speed of the motor and adjust the speed of the motor to inject the correct chemicals as necessary. can do

(22) The controller displays the number of revolutions of the motor, the flow rate of the raw water, and the input amount of the chemical on the number plate so that the user can check whether the chemical is injected at any time.

Devices that inject quantitative drugs using conventional metering pump could inject quantitative drugs.

This method installs a reverse valve on the suction port side and the discharge port side so that the suction port is open when the reverse valve is inhaled, the discharge port is closed, and the suction port is closed when discharging, and the discharge port is flowed in only one direction. However, drugs that crystallize or sludge in chemicals are mostly incapable of introducing chemicals due to crystals or sludges in the reverse zone, which prevents the checkball from playing a role and leaks.

The present invention, when the main inlet rotates to contact the inlet side, the piston sucks the chemicals, and when it contacts the outlet side, the piston is forcibly pushed out and does not install the reverse displacement which is a disadvantage of the conventional metering pump. Drugs can be injected without being affected

The present invention rotates the main inlet to contact the inlet port, and the piston inhales the chemical liquid. When the piston contacts the outlet port, the piston is forcibly pushed out to inject the chemical liquid. Since the inlet is installed in the inlet and outlet, the suction and discharge are in close contact with the suction and discharge, and the chemical liquid is added, so that even if sludge or crystals are formed, they cannot be held in place, and the lake presser is made to block the lake. Since double backflow is prevented, chemicals can be injected without being affected by sludge or crystals.

The configuration of the present invention has a feed shaft (4) that rotates according to the flow rate and flow rate by installing an inpeller in the power supply motor and the unpowered water supply pipe, and the feed shaft includes (1) an inlet and (5) a piston (6 ) Reciprocating shaft (8) Reciprocating spring (10) Install by connecting the lake opening and closing ring (4) to rotate like a feed shaft, and the case is fixed, and the case is fixed (2) suction port (3) discharge port (7) Flow control screw (12) Lake opening shaft (13) Lake presser (14) Land opening and closing shaft is fixed without rotation, and the lake opening and closing shaft and lake presser make reciprocating motion (1) The inlet is rotated in close contact with (2) the inlet and (3) the outlet. When the piston is inhaled, the inlet contacts the inlet and inhales the chemical, and when the piston is ejected, it contacts the outlet and discharges the chemical. (6) King The double shaft is 1/2 high and 1/2 low, and the middle is inclined. (7) It rotates in contact with the flow adjusting screw, and this height difference is the maximum reciprocating distance of the piston, and the reciprocating shaft has four holes for reciprocating motion. When the rod is erected, the rotation is like the feed shaft and the reciprocating motion is pushed out by the reciprocating spring (8) and when pushed in by the support of the fixed flow adjusting screw. (7) Turn the flow adjusting screw to the left to go out, and to the right to go inside to make the reciprocating shaft move longer, and when it goes out, the reciprocating shaft will shorten its travel distance. The piston reciprocates like the reciprocating shaft, and this flow adjusting screw If the reciprocating distance of the piston is adjusted, the reciprocating distance of the reciprocating shaft is controlled by the flow adjusting screw to adjust the amount of chemical input.The area where the reciprocating shaft of the flow adjusting screw comes in contact with the reciprocating shaft is rotated. (12) Lake opening and closing shaft and (13) Lake pressing shaft (14) Lake opening and closing shaft are symmetrically installed on both inlet and outlet sides and (10) Eccentricity due to rotation of lake opening and closing ring (12) The lake opening and closing shaft is pushed out when it comes into contact with the raised part. (13) The lake tapping rod is pushed out to open the lake to open the liquid.On the other side, the lake opening and closing shaft is contacted by the spring opening and closing shaft. It prevents the backflow of chemicals by returning to the lake and thus prevents the backflow of (1) the inlet through (2) the inlet and (3) the outlet and prevents the minute backflow when rotating. The lake opening / closing ring is installed eccentrically to one side of the inner diameter of the lake. (1) The high part should be installed in the same direction as the inlet to open the lake when the inlet is inhaled and discharged.

The automatic controlled quantitative medicine dispenser of the present invention is a constant water supply because the residual chlorine concentration decreases during the period between the drainage water and water purification plant at the end of the drainage basin in rural areas, military units, schools, recreational forests, temples, etc., which use groundwater and valley water as main water sources. Nevertheless, it will be installed at the end of the metropolitan water supply system which does not meet the standard as drinking water, and will prevent water-borne diseases, and it will be very helpful for sterilization and disinfection of water treatment in sewage terminal treatment plants.
