Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a dosing device for preventing chemical crystallization and blockage. Background Technology

[0002] In many fields such as industrial production and environmental protection, chemical dosing devices are key equipment to ensure production processes and treatment effects.

[0003] In existing chemical dosing devices, when rapid addition of chemicals is required and the chemical flow rate is too high, the chemical flow speed inside the feed pipe increases, which can easily lead to turbulence. This causes the chemical to accumulate locally inside the feed pipe, affecting the normal addition and effectiveness of the chemical. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing drug dosing devices are prone to blockage inside the feed pipe due to excessive drug flow during use, which affects the normal addition and use effect of the drug. Therefore, we propose a dosing device to prevent drug crystallization and blockage.

[0005] To achieve the above objectives, this application adopts the following technical solution: a dosing device for preventing drug crystallization and blockage, comprising a support frame, a dosing tank mounted on the top of the support frame, a feed pipe fixedly connected to the top of the dosing tank, a discharge pipe fixedly connected to one end of the dosing tank, a movable groove opened on one side of the feed pipe, an adjusting plate slidably connected inside the movable groove, a fixing block fixedly connected to one side of the feed pipe, a slot opened at the bottom of the adjusting plate, multiple slots opened at both ends of the inner cavity of the slot, a movable groove opened at the top of the fixing block, a through groove opened at both ends of the inner cavity of the movable groove, a pressing block slidably connected inside the through groove, a connecting plate fixedly connected to one end of the pressing block, and a locking block fixedly connected to the top of the connecting plate.

[0006] Preferably, the surface of the card block is slidably connected to the inside of the card slot, and the outer diameter of the card block is adapted to the inner diameter of the card slot.

[0007] Preferably, one end of the connecting plate has a round hole, and a round rod is fixedly connected inside the movable groove.

[0008] Preferably, a return spring is fixedly connected to one end of the connecting plate, and one end of the return spring is fixedly connected to the interior of the movable groove.

[0009] Preferably, the adjusting plate is made of a high corrosion-resistant alloy material.

[0010] Preferably, both ends of the feed pipe are fixedly connected to extension blocks, one end of the extension block is fixedly connected to a guide block, and both ends of the adjusting plate are provided with guide grooves.

[0011] Preferably, a tension spring is fixedly connected to one side of the guide block, and one side of the tension spring is fixedly connected to one side of the inner cavity of the guide groove.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, the operator moves an adjusting plate while simultaneously creating an inclined moving groove on one side of the feed pipe. The adjusting plate slides inside the moving groove. When it reaches the appropriate position, the operator moves a pressing block, which drives a connecting plate to insert a locking block into the locking groove, thus fixing the position of the adjusting plate. This changes the size of the feed pipe opening. When a small amount of reagent needs to be added, the adjusting plate is slid to a smaller opening position, allowing the reagent to enter the dosing tank slowly and evenly. When a large amount of reagent needs to be added, the adjusting plate is slid to a larger opening position, thereby avoiding crystallization blockage caused by excessive reagent flow.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figures 1-5 As shown, this utility model provides a technical solution: a dosing device for preventing drug crystallization and blockage, including a support frame 1, a dosing tank 2 installed on the top of the support frame 1, a feed pipe 3 fixedly connected to the top of the dosing tank 2, a discharge pipe 21 fixedly connected to one end of the dosing tank 2, a movable groove 4 opened on one side of the feed pipe 3, an adjusting plate 5 slidably connected inside the movable groove 4, a fixing block 6 fixedly connected to one side of the feed pipe 3, a slot 7 opened at the bottom of the adjusting plate 5, multiple slots 8 opened at both ends of the inner cavity of the slot 7, a movable groove 9 opened at the top of the fixing block 6, through grooves 10 opened at both ends of the inner cavity of the movable groove 9, a pressing block 11 slidably connected inside the through groove 10, and a connecting piece fixedly connected to one end of the pressing block 11. Plate 12, the top of the connecting plate 12 is fixedly connected to a locking block 13. The operator moves the adjusting plate 5, and at the same time, an inclined moving groove 4 is opened on one side of the feed pipe 3. At this time, the adjusting plate 5 slides inside the moving groove 4. When it moves to the appropriate position, the operator moves the pressing block 11, which drives the connecting plate 12, and inserts the locking block 13 into the locking groove 8 to fix the position of the adjusting plate 5. This changes the opening size of the feed pipe 3. When a small amount of reagent needs to be added, the adjusting plate 5 is slid to the smaller opening position, so that the reagent enters the dosing tank 2 slowly and evenly. When a large amount of reagent needs to be added, the adjusting plate 5 is slid to the larger opening position, thereby avoiding the crystallization blockage problem caused by excessive reagent flow.

[0022] Reference Figure 4 and Figure 5 As shown in this embodiment: the surface of the card block 13 is slidably connected to the inside of the card slot 8, the outer diameter of the card block 13 is adapted to the inner diameter of the card slot 8, and the tight fit design of the card block 13 and the card slot 8 ensures the stability of the adjustment plate 5 in a fixed position and effectively prevents the opening size from changing due to the loosening of the adjustment plate 5 during the drug addition process.

[0023] Reference Figure 5 As shown in this embodiment: a circular hole 14 is provided at one end of the connecting plate 12, and a circular rod 15 is fixedly connected inside the movable groove 9. The circular hole 14 is movably sleeved on the outer surface of the circular rod 15. The sleeved design of the circular hole 14 and the circular rod 15 not only provides guidance for the movement of the connecting plate 12, but also enhances the stability of the connecting plate 12 during the movement process, and avoids misalignment between the locking block 13 and the locking groove 8 caused by shaking.

[0024] Reference Figure 5As shown in this embodiment: a return spring 16 is fixedly connected to one end of the connecting plate 12, and one end of the return spring 16 is fixedly connected to the inside of the movable groove 9. The setting of the return spring 16 enables the connecting plate 12 to automatically reset to the initial position when it is not subjected to external force, thereby driving the locking block 13 to lock into the corresponding locking groove 8, realizing the rapid reset and fixation of the adjusting plate 5.

[0025] Reference Figure 4 As shown in this embodiment, the regulating plate 5 is made of a high corrosion-resistant alloy material. The regulating plate 5 made of high corrosion-resistant alloy material has excellent corrosion resistance and high strength, and can operate stably for a long time in harsh chemical environments. It is not easily corroded or eroded by chemicals.

[0026] Reference Figure 3 and Figure 4 As shown in this embodiment: both ends of the feed pipe 3 are fixedly connected to extension blocks 17, one end of the extension block 17 is fixedly connected to a guide block 18, and both ends of the adjusting plate 5 are provided with guide grooves 19. The cooperation between the guide block 18 and the guide groove 19 can effectively guide and restrict the movement trajectory of the adjusting plate 5 during movement, ensuring the stability and accuracy of the adjusting plate 5 during movement.

[0027] Reference Figure 4 As shown in this embodiment: a tension spring 20 is fixedly connected to one side of the guide block 18, and one side of the tension spring 20 is fixedly connected to one side of the inner cavity of the guide groove 19. The tension spring 20 can provide a continuous tension to the guide block 18 after the adjusting plate 5 moves to the designated position, and can quickly reset when the adjusting plate 5 is released from the fixed position.

[0028] Working principle: The operator moves the adjusting plate 5 while simultaneously creating an inclined moving groove 4 on one side of the feed pipe 3. The adjusting plate 5 slides inside the moving groove 4. When it reaches the appropriate position, the operator moves the pressing block 11, causing the connecting plate 12 to move the locking block 13 into the locking groove 8, fixing the position of the adjusting plate 5. This changes the opening size of the feed pipe 3. When a small amount of reagent needs to be added, the adjusting plate 5 is slid to a smaller opening position, allowing the reagent to enter the dosing tank 2 slowly and evenly. When a large amount of reagent needs to be added, the adjusting plate 5 is slid to a larger opening position, thus avoiding crystallization blockage caused by excessive reagent flow. The tight fit between the locking block 13 and the locking groove 8 ensures the stability of the adjusting plate 5 in its fixed position, effectively preventing changes in the opening size due to loosening of the adjusting plate 5 during reagent addition. The round hole 14 is movably sleeved on the outer surface of the round rod 15. This sleeved design not only facilitates connection... The movement of plate 12 provides guidance and enhances the stability of the connecting plate 12 during movement, preventing misalignment between the locking block 13 and the locking groove 8 due to shaking. The return spring 16 allows the connecting plate 12 to automatically return to its initial position when no external force is applied, thereby driving the locking block 13 to engage in the corresponding locking groove 8, achieving rapid reset and fixation of the adjusting plate 5. The adjusting plate 5, made of high corrosion-resistant alloy material, has excellent corrosion resistance and high strength, and can operate stably for a long time in harsh chemical environments, and is not easily corroded or eroded by chemicals. The cooperation between the guide block 18 and the guide groove 19 can effectively guide and limit the movement trajectory of the adjusting plate 5 during movement, ensuring the stability and accuracy of the adjusting plate 5 during movement. The tension spring 20 can provide a continuous tension to the guide block 18 after the adjusting plate 5 moves to the designated position, and can quickly reset when the adjusting plate 5 is released from fixation.
