Description

An automatic salt-adding device for a screw-propelled salt chlorinator Technical Field

[0001] This utility model relates to the field of salt chlorinator technology, specifically to an automatic salt adding device for a screw-propelled salt chlorinator. Background Technology

[0002] A salt chlorinator, also known as a brine electrolysis cell or brine chlorination system, is a device used for disinfecting swimming pools. Unlike the traditional method of directly adding chlorine to pool water, a salt chlorinator generates hypochlorous acid (an effective disinfectant) in the water through electrolysis, thereby purifying the water.

[0003] The salt chlorination machine includes an electrolysis system and a salt treatment system. In the salt treatment system, salt needs to be manually added to the salt tank for mixing and stirring. This method of adding salt is not only inefficient but also has poor precision, and needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic salt-adding device for a screw-propelled salt chlorinator, so as to solve the problems of low efficiency and low precision of manual salt addition in the salt tank of the salt chlorinator mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic salt-adding device for a spiral propulsion salt chlorinator, comprising a salt tank, a base on one side of the salt tank, a feeding cylinder on the base, a spiral conveying blade rotatably connected inside the feeding cylinder, a drive motor installed on one side of the feeding cylinder, a shaft on one side of the spiral conveying blade connected to the drive motor, a feeding hopper integrally connected to the top side of the feeding cylinder, a discharge pipe connected to the bottom side of the feeding cylinder, a solenoid valve installed on the discharge pipe, a plate-punch flow meter installed at the bottom of the solenoid valve, the plate-punch flow meter being electrically connected to the solenoid valve, and the lower end of the discharge pipe being connected to the salt tank.

[0006] Preferably, the top of the salt bucket is threadedly connected to a cover, and the cover has a through hole, into which a feed pipe is inserted.

[0007] Preferably, the outer wall of the feed pipe is fitted with a sealing plug, and the sealing plug is made of corrosion-resistant rubber.

[0008] Preferably, the lower end of the sealing plug is located between the feed pipe and the cover body, and the sealing plug is used for sealing and reinforcement.

[0009] Preferably, a sealing door is hinged to the top side of the feeding hopper, and an isolation net is fixedly connected to the inner wall of the sealing door.

[0010] Preferably, a non-woven bag is placed between the isolation net and the sealing door, and the inside of the non-woven bag is filled with desiccant.

[0011] Preferably, a base is provided on one side of the salt barrel, and an angle-adjusting electric cylinder is provided on the base. The top of the angle-adjusting electric cylinder is rotatably connected to the outer wall of the feeding cylinder, and the bottom of the feeding cylinder is rotatably connected to the base via a shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This device can automatically add salt and is convenient to control the amount of salt added, thus improving the accuracy of salt addition.

[0014] (2) This device has a feeding cylinder installed at an angle on one side of the salt tank. The feeding cylinder is equipped with an automatically rotating spiral conveying blade. The spiral conveying blade can realize the automatic spiral conveying of salt, so that the salt moves into the discharge pipe. At the same time, by installing a solenoid valve and a plate flow meter on the discharge pipe, the amount of salt falling can be detected, thereby controlling the opening and closing of the solenoid valve in time, improving the efficiency and accuracy of salt addition.

[0015] (3) By placing a desiccant inside the sealed door of the feeding hopper, this device can prevent the salt from being exposed to the air and coming into contact with humid air for a long time, thereby ensuring the dryness of the salt. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4. This utility model provides a technical solution: an automatic salt-adding device for a screw-propelled salt chlorinator, including a salt tank 12. A base 13 is provided on one side of the salt tank 12. A cover 11 is threadedly connected to the top of the salt tank 12. A through hole is provided on the cover 11, and a feeding pipe 8 is inserted into the through hole. A sealing plug 15 is fitted on the outer wall of the feeding pipe 8. The sealing plug 15 is made of corrosion-resistant rubber. This structure can ensure the service life of the sealing plug 15. The lower end of the sealing plug 15 is located between the feeding pipe 8 and the cover 11. The sealing plug 15 is used for sealing and reinforcement. This structure makes the connection between the feeding pipe 8 and the cover 11 more stable through the sealing plug 15, while avoiding gaps and preventing salt from falling out of the gaps during the falling process. A base 13 is provided on one side of the salt tank 12. The system includes a base 13, on which an angle-adjusting electric cylinder 14 is mounted. The top of the angle-adjusting electric cylinder 14 is rotatably connected to the outer wall of the feeding cylinder 6, and the bottom of the feeding cylinder 6 is rotatably connected to the base 13 via a shaft. This structure allows the angle of the feeding cylinder 6 to be adjusted by the angle-adjusting electric cylinder 14, thereby adjusting the height of one end of the feeding cylinder 6 to ensure the connection between the discharge pipe 8 and the salt bucket 12. The feeding cylinder 6 is mounted on the base 13, and a spiral conveying blade 7 is rotatably connected inside the feeding cylinder 6. A drive motor 5 is mounted on one side of the feeding cylinder 6, which drives the spiral conveying blade 7 to rotate automatically. The shaft on one side of the spiral conveying blade 7 is connected to the drive motor 5. A feeding hopper 4 is integrally connected to the top side of the feeding cylinder 6, and a tight-fitting device is hinged to the top side of the feeding hopper 4. A sealing door 1 is fixedly connected to an isolation net 3 on its inner wall. This structure allows the salt material to be protected from dust. A non-woven bag 2 is placed between the isolation net 3 and the sealing door 1. The non-woven bag 2 is filled with desiccant 16. This structure prevents the desiccant 16 from dispersing. The desiccant 16 can be activated carbon. The desiccant 16 helps to keep the salt material in the feeding hopper 4 dry and prevents it from becoming damp. A discharge pipe 8 is connected to the bottom of the feeding cylinder 6. A solenoid valve 9 is installed on the discharge pipe 8. A plate flow meter 10 is installed at the bottom of the solenoid valve 9. The solenoid valve 9, the plate flow meter 10, and the drive motor 5 are controlled by a PLC so that the drive motor 5 and the solenoid valve 9 close after the plate flow meter 10 detects the appropriate flow rate. The flow meter 10 is electrically connected to the solenoid valve 9. The lower end of the feed pipe 8 is connected to the salt tank 12. In this application, the salt tank 12 mainly serves to clarify the connection position between the salt tank 12 and the feed pipe 8. Therefore, the existing configuration on the salt tank 12 is not fully presented in this application. The outlet of the salt tank 12 is connected to the electrolysis system. The main components of the plate flow meter 10 of this device are: impact plate detection plate: an inclined metal plate, usually made of stainless steel, which withstands the impact of materials; force sensor: installed on the back of the impact plate, a strain gauge or piezoelectric sensor that measures the force generated by the impact of materials; signal processor: converts the force signal into flow data and outputs it to the control system; working process: material falling: particles or powder fall freely from the silo or conveyor belt, vertically impacting the inclined impact plate.Force detection: The impact force is transmitted to the sensor through the impact plate. The sensor outputs an electrical signal. Signal processing: Based on a preset algorithm, such as a force-flow relationship model, the electrical signal is converted into an instantaneous flow rate value. Data output: The flow rate data is transmitted to the control terminal via an analog signal of 4-20mA or a digital interface RS485.

[0023] Working principle: When using the automatic salt adding device of the screw propulsion salt chlorinator, firstly, the sealing door 1 is rotated open, and then the salt is added into the inside of the feeding hopper 4. At the same time, the drive motor 5 drives the screw conveyor blades 7 to rotate. The screw conveyor blades 7 carry the salt from bottom to top to the inside of the discharge pipe 8. During the fall of the salt, the plate flow meter 10 automatically detects the flow rate of the salt. When the flow rate meets the set flow rate, the solenoid valve 9 and the drive motor 5 are closed, and the salt enters the salt tank 12 to mix with the liquid and then goes to the electrolysis system for processing. During the operation of the feeding hopper 4, the sealing door 1 can be closed. Under the action of the desiccant 16 inside the sealing door 1, the dryness of the salt can be maintained, ensuring the quality of the salt.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
