Description

Technical Field

[0001] This utility model relates to the field of water treatment, specifically to an automatic dosing device for water treatment. Background Technology

[0002] Natural water sources contain various pollutants, such as suspended solids, bacteria, viruses, organic matter, and heavy metals. In order to ensure water quality safety, water plants need to treat the water to ensure the safety and suitability of the water supply and make the tap water meet drinking water standards.

[0003] In water treatment, common treatment steps mainly include natural sedimentation, coagulation sedimentation or clarification, filtration, and disinfection. Additionally, depending on the raw water conditions, various water purification processes such as flotation, adsorption, and oxidation are employed. Chemical coagulation is a crucial step in water treatment at water plants. Chemical coagulation involves adding coagulants (PAC) and flocculants (PAM) to the raw water to accelerate the coagulation and flocculation of colloidal particles into larger particles. Coagulation and flocculation together are collectively referred to as coagulation.

[0004] To reduce the workload of chemical dosing and improve automation, an automatic chemical dosing device for water disinfection (Publication No.: CN217377405U; Application Date: 2022-06-14) is disclosed in the prior art. This device involves placing an appropriate amount of calcium hypochlorite cake inside a dosing cylinder, and then adjusting the position of the dosing cylinder and the dissolving basket to control the length of the dosing cylinder submerged in water at the bottom of the floating support block, thus controlling the dosage of calcium hypochlorite cake. The amount of slowly released cake can be adjusted according to the required amount of water to be disinfected. Two limiters fix the position of the dosing cylinder. In use, the automatic dosing device is placed in the water and floats on the surface for dosing. The submerged calcium hypochlorite cake is slowly released. After the cake gradually decreases in size and dissolves, the remaining cake falls into the water, achieving automatic, intermittent dosing of the same dosage. A single dosing operation can be performed unattended for extended periods, reducing the workload of the dosing personnel. However, the prior art still has the following shortcomings:

[0005] 1. Due to the design of the suspended support block, the dosing cylinder lacks stability and is prone to tipping over when encountering strong winds or water flow disturbances. This instability not only affects the accuracy of pesticide dosing but may also threaten the safe operation of the equipment.

[0006] 2. Adjusting the water inlet length of the dosing cartridge is quite cumbersome. Each adjustment requires a series of operations, including unscrewing the bolts, loosening the two limit switches, and then re-locking the limit switches after the dosing cartridge is adjusted to the desired position. This adjustment process is not only time-consuming and labor-intensive, but also increases the complexity of operation and the potential risk of human error. It is not conducive to quickly responding to changes in water quality and reduces the flexibility and efficiency of the system. Utility Model Content

[0007] The present invention aims to provide an automatic dosing device for water treatment, so as to solve the problem of inconvenient adjustment of the water inlet length of the dosing cylinder in the prior art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An automatic dosing device for water treatment includes a dosing cylinder with a dosing basket fixed to its bottom. The dosing cylinder is slidably mounted on the side wall of a water tank via a slider and a dovetail groove. The slider is fixedly connected to the dosing cylinder and is connected to a self-locking cylinder for driving the slider to slide up and down in the dovetail groove.

[0010] Preferably, as an improvement, a rack is vertically fixed on the side wall of the cartridge case, and a gear is rotatably connected to the side wall of the water tank. One side of the gear meshes with the rack, and the other side of the gear meshes with a scaled rack parallel to the rack, with graduations marked on the scaled rack.

[0011] Preferably, as an improvement, the cartridge case is a transparent cartridge case.

[0012] Preferably, as an improvement, the medicine basket is threadedly connected to the medicine cartridge.

[0013] Preferably, as an improvement, an auxiliary positioning component is connected between the slider and the dovetail groove. The auxiliary positioning component includes several positioning holes opened on both sides of the dovetail groove. The positioning holes are evenly distributed. Telescopic rods are fixed on both sides of the slider. A telescopic switch for controlling the extension and retraction of the telescopic rods is installed on the self-locking cylinder. After the telescopic rods are extended, they can be inserted into the positioning holes.

[0014] Preferably, as an improvement, the auxiliary positioning component includes an electromagnet fixed to the back of the slider and an iron plate fixed in the dovetail groove, and an energizer switch for controlling the on and off of the electromagnet is installed on the self-locking cylinder.

[0015] The principles and beneficial effects of this solution are as follows:

[0016] 1. Place an appropriate amount of pesticide cake into the cartridge. Adjust the length of the cartridge submerged in water according to the required water volume and quality, thereby adjusting the amount of pesticide cake released into the water. After the cartridge is submerged, the submerged pesticide cake is slowly released. Once dissolved, the remaining submerged pesticide cake falls into the water for further release. This achieves automatic dosing, allowing for unattended operation for extended periods after a single dosing cycle, reducing the workload of personnel. This solution directly adjusts the length of the cartridge submerged in water by using a self-locking cylinder to drive a slider within a dovetail groove. Adjustment is convenient. Once adjusted, the self-locking cylinder is closed, locking the cartridge in place. Compared to existing technologies where the cartridge floats on the water surface, this method provides greater stability.

[0017] 2. When the medicine cartridge descends, it can drive the gear to rotate via the rack, and then drive the scale rack to move upward via the gear. The scale rack is marked with graduations, which makes it convenient for the medicine dispenser to intuitively know the length of the medicine cartridge into the water, improves the accuracy of medicine cartridge adjustment, and thus improves the accuracy of the amount of medicine cake dissolved each time.

[0018] 3. The transparent cartridge makes it easy to observe the condition of the medicine cake inside.

[0019] 4. The threaded connection between the medicine basket and the medicine cartridge makes it easy to remove the medicine basket for replacement or repair.

[0020] 5. The auxiliary positioning components can assist in positioning the slider, improving its stability and consequently the stability of the cartridge. When using one type of auxiliary positioning component, after the cartridge is in position, pressing the telescopic switch causes the telescopic rod to extend horizontally from both sides of the slider and insert into the positioning holes, thus helping to fix the slider. When using another type of auxiliary positioning component, after the cartridge is in position, pressing the power switch energizes the electromagnet, causing it to adhere to the iron plate, thereby helping to fix the slider. Both of these auxiliary positioning components achieve good positioning results and are simple in structure and operation. Attached Figure Description

[0027] The following detailed description illustrates the specific implementation method:

[0028] The reference numerals in the accompanying drawings of the instruction manual include: 1. medicine cartridge; 11. medicine basket; 2. dovetail groove; 21. slider; 3. self-locking cylinder; 4. water tank; 5. rack; 51. gear; 52. graduated rack; 6. telescopic rod; 61. positioning hole; 7. iron plate; 71. electromagnet; 72. groove.

[0029] Example 1:

[0030] like Figure 1 and Figure 2 As shown, an automatic dosing device for water treatment includes a dosing cartridge 1. A dosing basket 11 is threadedly connected to the bottom of the cartridge 1. The cartridge 1 is slidably mounted on the side wall of a water tank 4 via a slider 21 and a dovetail groove 2. Specifically, a vertical dovetail groove 2 is formed on the side wall of the water tank 4 (in this embodiment, it is a water tank; in actual use, it can be installed on any water container requiring water treatment, such as a water tank). The slider 21 is slidably connected within the dovetail groove 2 and is fixedly connected to the back of the top of the cartridge 1 by bolts. A self-locking cylinder 3 is connected to the slider 21 to drive it to slide up and down within the dovetail groove 2. In actual use, the self-locking cylinder 3 can be installed on the side of the water tank 4. In other embodiments, the slider 21 can also be driven to slide by a motor and a ball screw.

[0031] In practical application, an appropriate amount of pesticide cake is placed in the pesticide cartridge 1 according to the required water volume and quality. Then, the self-locking cylinder 3 is activated to drive the slider 21, which lowers the pesticide cartridge 1 to a suitable position to adjust the water immersion length of the cartridge 1, thus adjusting the amount of pesticide cake dissolved each time. After the cartridge 1 reaches its position, the self-locking cylinder 3 is closed, and the cartridge 1 is positioned under the action of the self-locking cylinder 3. The pesticide cake in the water-immersed cartridge 1 undergoes slow-release dissolution in the water. After complete dissolution, the remaining pesticide cake falls into the water to continue dissolving. This achieves automatic pesticide addition, allowing for unattended operation for extended periods after a single addition, reducing the workload of the pesticide dosing personnel.

[0032] Example 2:

[0033] Combination Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that a vertical rack 5 is bolted to the side wall of the cartridge 1, and a gear 51 is rotatably connected to the side wall of the water tank 4 via a shaft and bearing. One side of the gear 51 meshes with the rack 5, and the other side of the gear 51 meshes with a graduated rack 52 parallel to the rack 5. The graduated rack 52 is marked with graduations. The lengths of the rack 5 and the graduated rack 52, as well as the position and size of the gear 51, are only schematic in the figure and can be adjusted according to requirements in actual use.

[0034] When the cartridge 1 descends, it drives the rack 5 to descend, the rack 5 drives the gear 51 to rotate, and the gear 51 drives the scale rack 52 to rise. The length of the scale rack 52 rising can be directly observed according to the scale on the scale rack 52, so as to know the length of the cartridge 1 in the water, thereby improving the adjustment accuracy of the cartridge 1.

[0035] Example 3:

[0036] The difference between this embodiment and Embodiment 1 is that the cartridge 1 is a transparent cartridge 1, such as a corrosion-resistant transparent plastic material or glass material. Using a transparent cartridge 1 makes it easier to observe the medicine cake inside the cartridge 1.

[0037] Example 4:

[0038] Combination Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that an auxiliary positioning component is connected between the slider 21 and the dovetail groove 2. The auxiliary positioning component includes several positioning holes 61 on both sides of the dovetail groove 2 (only one on one side is shown in the figure). The positioning holes 61 are evenly distributed. Telescopic rods 6 are bolted to both sides of the slider 21. A telescopic switch (not shown in the figure) for controlling the extension and retraction of the telescopic rods 6 is installed on the self-locking cylinder 3. After the telescopic rods 6 are extended, they can be inserted into the positioning holes 61. The size and installation position of the telescopic rods 6 and the positioning holes 61 in the figure are only schematic.

[0039] After the cartridge 1 descends to its position, press the telescopic switch to control the telescopic rod 6 to extend. After the telescopic rod 6 extends, it is inserted into the positioning hole 61, which can assist in positioning the slider 21, improve the stability of the slider 21 and the cartridge 1, and reduce the burden on the self-locking cylinder 3.

[0040] Example 5:

[0041] Combination Figure 5 and Figure 6 As shown, the difference between this embodiment and embodiment 4 is that the auxiliary positioning component includes an electromagnet 71 fixed to the back of the slider 21 and an iron plate 7 fixed in the dovetail groove 2. A power switch (not shown in the figure) for controlling the on and off of the electromagnet 71 is installed on the self-locking cylinder 3. Specifically, a groove 72 is opened on the back of the slider 21, and the electromagnet 71 is glued and fixed in the groove 72. The depth of the groove 72 is greater than the thickness of the electromagnet 71. The iron plate 7 is vertically bolted to the middle of the dovetail groove 2, which is aligned with the groove 72. When the slider 21 is in the dovetail groove 2, the parts of the slider 21 on both sides of the groove 72 can slide on the inner wall of the dovetail groove 2 on both sides of the iron plate 7, while the iron plate 7 extends into the groove 72 and is in contact with the electromagnet 71. This ensures that the electromagnet 71 is accurately attracted to the iron plate 7.

[0042] After the cartridge 1 descends to its position, press the power switch to energize the electromagnet 71. Once energized, the electromagnet 71 attracts the iron plate 7, thereby helping to fix the slider 21 and improving its stability.
