Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dosing devices, in particular to a dosing device for disinfecting domestic water. Background Art
[0002] Domestic water tanks often need to be disinfected by adding medicine. For secondary disinfection, chlorine dioxide powder is now widely used and added to tap water for water disinfection. Specifically, the staff usually add a sufficient proportion of water to the stock liquid medicine box first, and then manually add chlorine dioxide powder into the medicine box. The powder dissolves in the water to form a high-concentration stock liquid. At this time, the residual chlorine content of the stock liquid is very high, at a concentration of about 100 grams per liter.
[0003] When adding medicine, the metering pump will deliver the highly concentrated stock solution at a rate of 0.05 to 9 liters per hour. The metering pump, whose full name is the electromagnetic metering diaphragm pump, has a pumping pressure of 0.1 to 16 bar, and pumps the stock solution into the water tank in a pulse manner of 0 to 200 times per minute. The dosing pipe uses environmentally friendly and corrosion-resistant PE pipe. When the metering pump is working, because there is sufficient liquid pressure, the dosing pipe within two meters of the metering pump will produce violent and short telescopic swings due to the pulse work of the metering pump, so that the drug stock solution can be slowly and evenly added to the secondary water supply tank, thereby completing the disinfection of the water quality in the water tank.
[0004] However, when adding chlorine dioxide powder, some of the powder will react with water to volatilize residual chlorine gas and generate a large amount of heat. The staff will feel strong discomfort during the long process of pouring the powder. When the staff increases the speed of pouring the powder to avoid staying for a long time, the excessive powder will react violently with the water and emit a relatively loud explosion sound, which will impact the equipment shell and affect the service life of the equipment shell. The gas may also be accompanied by powder and sprayed out, causing damage to the human respiratory tract. Utility Model Content
[0005] The utility model provides a dosing device for domestic water disinfection. The device can replace manpower to slowly pour powder, thereby reducing the impact of the environment on workers as much as possible and reducing the high heat and explosive sound generated after the reaction.

The discharge port of the hopper is connected to the medicine inlet of a raw liquid medicine box, one side of the hopper is provided with an avoidance groove which passes through the interior of the hopper, one end of the rod passes through the avoidance groove and extends into the hopper, one side of the rod is connected to a ball hinge at the edge of the hopper, the connecting piece is fixedly connected to an end of the rod away from the hopper, a dosing pipe connected to the outlet of the metering pump passes through the connecting piece, so that the connecting piece relies on the pulse power of the dosing pipe to drive the rod to swing back and forth around the hinge ball, the baffle is placed in the hopper, the rod is fixedly connected to the baffle, and the size of the baffle is smaller than the discharge port of the hopper, so that the medicine leaks from the gap between the baffle and the discharge port into the raw liquid medicine box.
[0007] Preferably, the connecting piece includes a fixing block, the fixing block is provided with a through hole in a horizontal direction, and the dosing tube passes through the through hole horizontally.

[0011] Preferably, the baffle is provided with a plurality of sieve holes in the vertical direction.
[0012] Preferably, a guide groove is provided on one side of the avoidance groove in the hopper to enable the powder to continuously fall toward the discharge port.

[0024] refer to Figure 1 、 Figure 2 The utility model provides a dosing device for disinfecting domestic water, comprising: a hopper 1, a rod 3, a connecting member 4, a metering pump 5, and a baffle 7. The discharge port 13 of the hopper 1 is connected to the medicine inlet of the raw liquid medicine box 2. One side of the hopper 1 is provided with an avoidance groove 11 which passes through the interior of the hopper 1. One end of the rod 3 passes through the avoidance groove 11 and extends into the hopper 1. One side of the rod 3 is connected to the edge of the hopper 1 at a ball hinge. The connecting member 4 is fixedly connected to the end of the rod 3 away from the hopper 1. The dosing pipe 6 connected to the metering pump 5 passes through the connecting member 4, so that the connecting member 4 relies on the pulse power of the dosing pipe 6 to drive the rod 3 to swing back and forth around the hinge ball. The baffle 7 is placed in the hopper 1, and the rod 3 is fixedly connected to the baffle 7. The size of the baffle 7 is smaller than the size of the discharge port 13 of the hopper 1, wherein the baffle 7 is close to the top of the discharge port 13 in the hopper 1, so that the medicine leaks from the gap between the baffle 7 and the discharge port 13 to the raw liquid medicine box 2.
[0025] In the above embodiment, the funnel provided in the present device can realize the filling of the entire residual chlorine powder so that the staff can quickly dump the residual chlorine powder, avoiding the physical discomfort of the staff caused by the influence of the environment due to slow dumping. Specifically, the reciprocating swing of the rod 3 and the baffle 7 generates an offset vibration force, so that the powder on the baffle 7 slowly and gradually leaks down into the stock liquid medicine box 2 through the gap of the discharge port 13 during its vibration, replacing the slow dumping by manpower, greatly reducing or even avoiding the harm of dust, noise, high temperature and odor to the health of the staff. The present device cleverly utilizes the pulse power generated by the metering pump 5 to the dosing pipe 6 to drive each component to mechanically control the slow addition of residual chlorine powder into the stock liquid medicine box 2, without the need for additional mechanical force, saving energy and reducing the number of equipment components, thereby reducing the failure rate. The present device controls the amount of single addition, reduces the high heat generated after the reaction, and the reduction in heat will also reduce the volume of the explosion sound. At the same time, it also eliminates the impact of the explosion sound on the equipment casing.
[0026] Furthermore, the first embodiment of the swing of the rod 3, referring to Figure 2and Figure 3 The connecting member 4 includes a fixed block 41, which has a through hole 42 in the horizontal direction. The dosing tube 6 passes through the through hole 42 horizontally. The avoidance groove 11 extends in the horizontal direction. The vertical projection of the avoidance groove 11 is conical and is used to avoid the rod 3 swinging left and right.
[0027] In the above embodiment, by limiting the horizontal penetration of the dosing tube 6 through the through hole 42, it can be achieved that when the medicine in the dosing tube 6 is pulsed out by the metering pump 5, the dosing tube 6 will drive the fixed block 41 and the rod 3 to shift horizontally forward around the hinge ball. At this time, the baffle 7 will also shift in the opposite direction. At this time, the powder will leak down through the gap with the funnel discharge port 13. Specifically, after the medicine is added to the hopper 1, due to the static friction and the design of the device, if the rod 3 does not move, the medicine will be stuck in the dosing port and cannot enter the medicine box. After the dosing metering pump 5 is turned on, because the metering pump 5 works in a pulsed manner, the raw liquid is pumped into the water tank 8 in an impact manner. While pumping, the dosing pipe 6 will vibrate and swing synchronously, and the size of the swing will gradually decrease according to the size of the distance. The outlet pipe of the metering pump 5 is fixed to the fixed block 41. As the metering pump 5 works, the dosing pipe 6 vibrates synchronously, and the vibration is linked to the vibration of the dosing rod 3 through the fixed plate. Under the action of the lever, the distance change of the dosing pipe 61 mm is magnified to a position change of about 2 cm. The movement distance of the rod 3 at the dosing port is magnified, and the rod 3 dials the medicine in a horizontal position to add it to the medicine box. The working frequency of the metering pump 5 is about 40-80 times per minute, and the rod 3 also adds the medicine evenly to the medicine box at a frequency of 40-80 times per minute.
[0028] Further, the second embodiment of the swing of the rod 3, referring to Figure 4 、 Figure 5 and Figure 6 The connecting member 4 includes a fixed block 41, which has a through hole 42 in the vertical direction. The dosing tube 6 vertically penetrates the through hole 42. The avoidance groove 11 extends in the vertical direction, and the groove width is greater than the outer diameter of the rod 3. The horizontal projection of the avoidance groove 11 is conical, which is used to avoid the rod 3 swinging up and down. The baffle 7 has a plurality of sieve holes 71 in the vertical direction.
[0029] In the above embodiment, since the baffle 7 is also provided with a sieve hole 71, the sieve hole 71 is a sieve-shaped circular hole with a diameter of 2.5 mm (the hole diameter can be slightly larger than the diameter of the medicine), which is used to assist in spreading the medicine. The difference is that the horizontal left and right swinging and vibration method is changed to an up and down shaking method. This method is more suitable for medicines with smaller particles, such as the size of rice grains with a diameter of about 2 mm. The specific state is as follows.
[0030] After the medicine is added to the hopper 1, due to the static friction and the structural design of the dosing port, if the lever does not move, the medicine will be stuck in the dosing port and cannot enter the medicine box. After the dosing metering pump 5 is turned on, because the metering pump 5 works in a pulsed manner, the raw liquid is pumped into the water tank 8 in an impact manner. While pumping, the dosing pipe 6 will vibrate and swing synchronously, and the size of the swing gradually decreases according to the size of the distance. The outlet pipe of the metering pump 5 is fixed to the fixed block 41. As the metering pump 5 works, the dosing pipe 6 vibrates synchronously. The vibration is linked to the dosing rod 3 through the fixed plate to vibrate. Under the action of the lever, the up and down distance change of the dosing pipe 61 mm is magnified to an up and down position change of about 2 cm. The movement distance of the rod 3 of the dosing port is magnified, and the rod 3 dials the medicine in a horizontal position to add it to the medicine box. The working frequency of the metering pump 5 is about 40-80 times per minute, and the rod 3 also adds the medicine evenly to the medicine box at a frequency of 40-80 times per minute.
[0031] Further, refer to Figure 1 Considering that the avoidance groove 11 placed in the hopper 1 may cause powder to enter, a guide groove 12 is opened on one side of the avoidance groove 11 in the hopper 1 to allow the powder to continue to fall toward the discharge port 13.
[0032] In summary, the effect of this device is that it can add the residual chlorine powder into the hopper 1 at one time, and generate an offset vibration force through the reciprocating swing of the rod 3 and the baffle 7, so that the powder on the baffle 7 is slowly and gradually added to the stock liquid medicine box 2, which greatly reduces the time for the staff to add medicine and the time they stay in the dosing environment, and greatly reduces or even avoids the harm to the health of the staff caused by dust, noise, high temperature and odor. At the same time, this device also cleverly uses the pulse power generated by the metering pump 5 to the dosing pipe 6 to drive each component to mechanically control the slow addition of residual chlorine powder into the stock liquid medicine box 2, controls the amount of single addition, avoids excessive heat generated by the reaction, and the reduction of heat will greatly reduce the popping sound. At the same time, it also eliminates the impact of the popping sound on the equipment casing.
[0033] Specifically, in terms of the mechanical power source, the impact force generated by the metering pump 5 during drug addition is used as the mechanical force for slowly adding the powder, without the need for additional mechanical force. This saves energy, reduces the number of equipment components, and thus reduces the failure rate.
[0034] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
