Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a PAM dissolving device. Background Technology

[0002] PAM (polyacrylamide) is a high-molecular-weight polymer primarily used as a flocculant in wastewater treatment and drinking water purification. The charged groups of PAM can neutralize the opposite charge on the surface of suspended particles, reducing the repulsive forces between particles and promoting particle aggregation. The long-chain molecules of PAM can simultaneously adsorb multiple suspended particles, forming "bridges" between them, causing small particles to aggregate into large flocs, facilitating sedimentation or filtration.

[0003] The unique properties of PAM (particulate matter) cause PAM powder to easily form hydrophobic clumps when exposed to moisture in the environment. These clumps are difficult to dissolve in water, leading to fluctuations in reagent concentration and poor coagulation and sedimentation effects. Therefore, a PAM dissolving device is needed to solve the problems of PAM's susceptibility to moisture and clumping, as well as insufficient precision in reagent concentration preparation. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, this utility model provides a PAM dissolving device to solve the technical problems of PAM being prone to moisture and clumping and insufficient accuracy of drug concentration in the prior art.

[0005] This utility model embodiment provides a PAM dissolving device, including:

[0006] A dissolving tank, a maturation tank, and a storage tank are sequentially connected along the direction of water flow.

[0007] It also includes a drug storage compartment containing PAM drug, and the drug storage compartment is equipped with a drying device to prevent the PAM drug from getting damp and a drug delivery device to transport the PAM drug to the dissolving tank.

[0008] The system also includes an electrical control cabinet, which is electrically connected to the water inlet pipe, the water outlet pipe, the stirring device, and the drug delivery device. The electrical control cabinet is used to control the opening and closing of the water inlet pipe and the water outlet pipe, as well as to control the opening and closing of the stirring device and the drug delivery device.

[0009] In one embodiment, the system further includes a dispensing chamber located at the dispensing port of the dissolving tank. Inside the dispensing chamber is a weighing platform located below the end of the delivery device. This platform is capable of measuring the weight of the PAM medication accumulated on it. A delivery device is also installed on the weighing platform, which can add the PAM medication accumulated on the weighing platform to the dispensing port of the dissolving tank. Both the weighing platform and the delivery device are electrically connected to an electrical control cabinet. The electrical control cabinet can receive the weight data measured by the weighing platform and control the opening and closing of the delivery device based on the received weight data.

[0010] In one embodiment, the drug delivery device adopts the structure of a screw conveyor.

[0011] In one embodiment, a flow meter is installed on the water inlet pipe, and the flow meter is electrically connected to the electrical control cabinet.

[0012] In one embodiment, a level gauge is installed inside the medicine storage tank, and the level gauge is electrically connected to the electrical control cabinet.

[0013] In one embodiment, the dissolving tank and the maturation tank, as well as the maturation tank and the storage tank, are separated by paired partitions, and the paired partitions are arranged in an alternating manner to form an S-shaped water flow channel connecting the two tanks.

[0014] Compared with the prior art, the beneficial effects of the PAM dissolving device provided in this embodiment of the present invention are as follows: The drug storage chamber of this embodiment of the present invention is equipped with a drying device, which can dry the PAM drug powder in the chamber at regular intervals to ensure that the PAM drug powder is dry and avoids moisture and clumping.

[0026] The principles and features of this utility model are described below with reference to the accompanying drawings. The embodiments described are only for explaining this utility model and are not intended to limit the scope of this utility model. The following description, in conjunction with... Figure 1-2 The preferred embodiments of this utility model will be described in further detail below:

[0027] like Figure 1As shown, this embodiment of the present invention provides a PAM dissolving device, comprising:

[0028] A dissolving tank 7, a maturation tank 8, and a storage tank 9 are sequentially connected along the direction of water flow. A water inlet pipe 12 is installed at the dissolving tank 7, and a water outlet pipe 14 is installed at the storage tank 9. Both the dissolving tank 7 and the maturation tank 8 are equipped with a stirring device 6 (the stirring device 6 is purchased as a finished product).

[0029] It also includes a drug storage chamber 1, which stores PAM drug and is equipped with a drying device to prevent the PAM drug from getting damp and a drug delivery device 2 to transport the PAM drug to the dissolving tank 7.

[0030] And an electrical control cabinet 11, which has a built-in power distribution board and a PLC automatic control system. The electrical control cabinet 11 is electrically connected to the water inlet pipe 12, the water outlet pipe 14, the stirring device 6 and the medicine delivery device 2, and is used to control the opening and closing of the water inlet pipe 12 and the water outlet pipe 14, as well as the opening and closing of the stirring device 6 and the medicine delivery device 2.

[0031] In one embodiment, the drying device can be implemented by arranging electric heating plates on the walls around the drug storage chamber 1 to ensure a dry environment for the drug storage chamber 1 and prevent the PAM drug from getting damp. The drying device can be set with parameters such as heating start time, start duration, and start interval. The relevant parameters are optimized and adjusted in the electrical control cabinet 11 according to the humidity of the area where the equipment is located.

[0032] In one embodiment, to ensure the accuracy of the drug concentration, the dissolving equipment further includes a dispensing chamber 3, which is located at the drug addition port of the dissolving tank 7. Inside the dispensing chamber 3 is a weighing platform 4, which can be implemented using a commercially available electronic scale. The weighing platform 4 is located below the end of the drug delivery device 2 and can obtain the weight of the PAM drug accumulated on it. A drug delivery device 5 is also installed on the weighing platform 4, which can add the PAM drug accumulated on the weighing platform 4 to the drug addition port of the dissolving tank 7. Both the weighing platform 4 and the drug delivery device 5 are electrically connected to an electrical control cabinet 11. The electrical control cabinet 11 can receive the weight data measured by the weighing platform 4 and control the opening and closing of the drug delivery device 5 based on the received weight data. In one embodiment, as shown... Figure 2As shown, the weighing platform is fixed on the bottom plate of the dispensing chamber 3. At this time, the drug administration device 5 includes a scraper and a telescopic rod. The telescopic rod is adjusted for extension and retraction under the control of the electrical control cabinet 11, thereby driving the scraper to slowly push the PAM agent accumulated on the surface of the weighing platform to the drug dispensing tank 7. In another embodiment, the weighing platform can be set on the bottom plate of the dispensing chamber 3 in a hinged form. At this time, the drug administration device 5 can be set as a telescopic rod with both ends hinged to the weighing platform and the bottom plate of the dispensing chamber 3 respectively. The telescopic rod is adjusted for extension and retraction under the control of the electrical control cabinet 11, thereby driving the weighing platform to tilt so that the PAM agent accumulated on it slides down to the drug dispensing tank 7. Of course, in order to avoid the agent spilling outside the drug dispensing tank 7, a funnel-shaped receiving structure can also be added to the drug dispensing tank 7.

[0033] In one embodiment, the drug delivery device 2 is implemented by purchasing a finished screw conveyor. On the one hand, the drug delivery device 2 in the form of a screw conveyor can estimate the amount of drug to be added to a certain extent by the running time. On the other hand, the screw conveyor can also have a certain dispersing effect on the PAM agent to ensure its powder state and avoid the agent from entering the subsequent process flow as a large agglomerate.

[0034] Typically, in one embodiment, the inlet pipe 12 can be directly connected to the tap water pipe. In this case, the amount of water entering the dissolving tank 7 can be estimated by the on / off time of the inlet pipe 12. Of course, in another embodiment, in order to improve the pumping capacity, the inlet pipe 12 and the outlet pipe may also include necessary pumps and valves. Moreover, in order to obtain a more accurate inlet volume so as to accurately control the dissolving concentration, a flow meter 13 is provided on the inlet pipe 12, and the flow meter 13 is electrically connected to the electrical control cabinet 11.

[0035] In one embodiment, in order to ensure a sufficient supply of medicine in subsequent processes, a level gauge 10 is installed in the medicine storage tank 9, and the level gauge 10 is electrically connected to the electrical control cabinet 11. The level gauge 10 can be used to obtain the amount of medicine in the medicine storage tank 9 in a timely and accurate manner, and then the start and stop of the dissolving equipment can be controlled by the level of the liquid.

[0036] In one embodiment, to ensure sufficient dissolution time for the PAM agent entering the dissolving tank 7 and to maintain stable drug concentration in the storage tank 9, thus preventing water circuit short-circuiting (i.e., the added PAM agent flowing to the storage tank 9 before complete dissolution), the dissolving tank 7 and the maturation tank 8, as well as the maturation tank 8 and the storage tank 9, are separated by paired partitions 15. These paired partitions 15 are staggered to form an S-shaped water flow channel connecting the two tanks. In one embodiment, the paired partitions 15 are positioned to the left of… In one embodiment, the partitions are arranged in a staggered manner, meaning that one vertical edge of the partition is connected to the side wall of the pool, while the other vertical edge is separated from the side wall by a distance, forming a horizontal S-shaped water flow channel between the two partitions. In another embodiment, the paired partitions 15 are arranged in a vertically staggered manner, meaning that the top of one partition is connected to the top of the pool and its bottom is separated from the bottom of the pool by a distance, while the top of the other partition is separated from the top of the pool and its bottom is connected to the pool body, forming a vertical S-shaped water flow channel between the two partitions. This arrangement ensures that the reagent has sufficient dissolution time. Figure 1 The embodiment shown employs a vertical S-shaped water flow channel.

[0037] When solution preparation is required, PAM powder is conveyed to the weighing platform of the dispensing scale 3 via the dispensing device 2. The amount of powder conveyed can be roughly controlled by the running time of the dispensing device 2 to avoid overdosing. For precise preparation, the dosage can be controlled by weighing on the weighing platform in the dispensing chamber 3. The weighing platform feeds back the weight of the powder to the electrical control cabinet 11, which calculates the required water intake at the set concentration and then controls the water intake through the water inlet pipe 12 (e.g., ...). Tap water is added through the inlet pipe 12. At the same time, the electromagnetic flow meter 13 records the inlet water flow and feeds it back to the electrical control cabinet 11 in real time. When dissolving the medicine, the inlet pipe 12 is started first to ensure that there is a certain amount of basic water in the dissolving tank 7. Then the stirring device 6 is started. When the inlet water volume reaches the required level, the dosing device 5 will start to slowly deliver the medicine to the dosing port and drop it into the dissolving tank 7. Throughout the dosing process, the stirring device 6 must always be kept running to avoid the medicine from clumping. To avoid the dosing port from getting wet, the dosing port and the water inlet should be located on both sides of the dissolving tank 7. Throughout the process, the start and stop of the entire equipment can be controlled by the level gauge 10 installed in the storage tank 9 to ensure that the amount of medicine in the storage tank 9 is sufficient.

The scope of protection of this utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this utility model.
