In order to improve production efficiency, continuous production is usually adopted in the current production of scale inhibitors. However, in continuous production, raw materials need to be added manually at regular intervals, which can easily affect the production efficiency of scale inhibitors.
[0003] Therefore, this utility model provides an automatic scale inhibitor feeding device to solve the above problems. Utility Model Content
[0004] The technical problem to be solved by this utility model is that manual feeding in the production of scale inhibitors affects production efficiency.
[0005] This utility model provides the following technical solution: an automatic scale inhibitor feeding device, comprising a vessel body and an automatic feeding assembly, wherein the automatic feeding assembly is installed inside the vessel body, and a first liquid inlet is fixedly installed on the top of the vessel body. The automatic feeding assembly includes a float, a connecting body, a transmission body, and a blocking body. The float is slidably installed inside the vessel body, the connecting body is fixedly installed on the vessel body, and the blocking body is slidably installed inside the vessel body below the first liquid inlet. A transmission body is installed inside the vessel body to drive the blocking body to move horizontally. The longitudinal movement of the float is achieved by the connecting body driving the transmission body and simultaneously driving the blocking body to move horizontally, thus realizing automatic feeding.
[0006] The transmission body includes a mounting shaft and a gear. The surface of the connecting body is provided with teeth. The mounting shaft is installed inside the vessel body, and the gear that meshes with the connecting body is installed on the surface of the mounting shaft.
[0007] The blocking body includes a horizontal rack and a baffle plate. The baffle plate is slidably installed on the inner wall of the top of the vessel body, and a horizontal rack of a meshing gear is fixedly installed on the side of the baffle plate near the gear.
[0008] An auxiliary rod is fixedly installed on the inner wall of the top of the float, and the float is slidably mounted on the surface of the auxiliary rod.
[0009] The length of the auxiliary rod is less than the height of the vessel body, a limit body is fixedly installed at the lower end of the auxiliary rod, and a side stirring assembly is rotatably installed inside the auxiliary rod.
[0010] An installation shaft is fixedly installed inside the vessel body, and a gear is rotatably installed on the surface of the installation shaft. The gear includes a first tooth and a second tooth fixed on the same axis. The connecting body meshes with the first tooth, and the horizontal rack meshes with the second tooth.
[0011] A second liquid inlet is provided at the top of the vessel body adjacent to the first liquid inlet. An installation shaft is rotatably installed inside the vessel body. A gear is fixedly installed on the surface of the installation shaft. The gear includes a first tooth, a second tooth, and a third tooth that are coaxially fixed. The connecting body meshes with the first tooth. The blocking body below the first liquid inlet and the second liquid inlet meshes with the second tooth and the third tooth, respectively.
[0012] The liquid inlet, transmission body, and blocking body are symmetrically installed in two sets along the axis of the vessel body.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. This utility model, through the cooperation of a float, a transmission body, and a barrier, causes the float to move longitudinally when the liquid level is floating, thereby driving the transmission body to rotate and causing the barrier to move horizontally to open the liquid inlet. This allows for automatic feeding based on the liquid level in the vessel, thus maintaining a stable dynamic balance of the liquid level in the vessel. Furthermore, it can also control the automatic feeding of different raw materials.
[0015] 2. In this invention, while the float follows the liquid level to control automatic feeding, the side agitator inside the auxiliary rod can also work in sync with the agitator structure at the shaft center to agitate, thereby improving the reaction effect in the scale inhibitor production process.

[0027] In view of the problem that manual feeding affects production efficiency in the production of scale inhibitors, this disclosure provides an automatic feeding device for scale inhibitors.
[0028] Example 1: As Figures 1 to 3 As shown, an automatic scale inhibitor feeding device includes a vessel body 1 and an automatic feeding assembly. The automatic feeding assembly is installed inside the vessel body 1. A first liquid inlet 11 is fixedly installed on the top of the vessel body 1. The automatic feeding assembly includes a float 2, a connecting body 3, a transmission body 4, and a blocking body 5. The float 2 is slidably installed inside the vessel body 1. The connecting body 3 is fixedly installed on the vessel body 1. The blocking body 5 is slidably installed below the first liquid inlet 11 inside the vessel body 1. The transmission body 4 is installed inside the vessel body 1 to drive the blocking body 5 to move horizontally. The longitudinal movement of the float 2 drives the transmission body 4 through the connecting body 3 and simultaneously drives the blocking body 5 to move horizontally, thereby achieving automatic feeding.
[0029] like Figure 2 and 3 As shown, it should be noted that the stirring structure 6 of the prior art is installed at the axis of the vessel body 1. For example, a drive motor 61 is fixedly installed on the top of the vessel body 1, and a stirring blade 62 is rotatably installed at the axis of the vessel body 1. The drive motor 61 drives the stirring blade 62 to rotate and stir.
[0030] like Figure 2 and 3 As shown, the bottom of the vessel body 1 is provided with a discharge port 12. Based on this, any auxiliary discharge structure in the prior art can be used for discharge, such as pump conveying discharge and screw conveyor.
[0031] During the continuous production of scale inhibitor, the processed raw materials in reactor 1 flow out through outlet 12, while simultaneously entering through the first inlet 11, thus achieving dynamic balance and continuous feeding. This means that while continuously discharging the processed material from reactor 1 and adding raw materials into reactor 1, a dynamic balance of the raw material water level within reactor 1 is maintained.
[0032] In this embodiment of the disclosure, the liquid level inside the vessel 1 is maintained at 80% of its volume, thereby ensuring processing efficiency while avoiding material accumulation that could lead to overpressure.
[0033] During the process of raw materials being discharged from the outlet 12 and maintaining a stable liquid level in the vessel body 1, when the liquid level drops due to the discharge of raw materials, the float 2 moves down synchronously, thereby driving the connecting body 3 to move down and driving the transmission body 4 to drive the blocking body 5 to slide horizontally open the first liquid inlet 11. Thus, when the liquid level drops, the first liquid inlet 11 is opened to allow feeding. After feeding restores the liquid level of the float 2, the float 2 drives the connecting body 3 to move up and drives the transmission body 4 and the blocking body 5 to block the first liquid inlet 11 to stop feeding, thereby maintaining a stable liquid level in the vessel body 1.
[0034] It should be noted that when the scale inhibitor is reacted, the raw materials added, such as organic phosphonic acid, polycarboxylic acid or inorganic phosphate, dissolve in water, which increases the solute concentration of the raw materials in the float 2, thereby ensuring the stability of the buoyancy of the raw materials in the float 2.
[0035] The float 2 described in this embodiment is made of hollow plastic or rubber material, which enhances buoyancy and ensures stable floating.
[0036] like Figure 2 and 3 As shown, the transmission body 4 includes a mounting shaft 41 and a gear 42. The surface of the connecting body 3 is provided with teeth. The mounting shaft 41 is installed inside the vessel body 1. The gear 42 that meshes with the connecting body 3 is installed on the surface of the mounting shaft 41.
[0037] like Figure 2 and 3 As shown, the blocking body 5 includes a horizontal rack 52 and a baffle plate 51. The baffle plate 51 is slidably installed on the inner wall of the top of the vessel body 1. The horizontal rack 52 of the meshing gear 42 is fixedly installed on the side of the baffle plate 51 near the gear 42.
[0038] It should be noted that the horizontal rack 52 has an L-shaped structure and is fixedly connected to the bottom of the barrier plate 51.
[0039] like Figure 2 and 3 As shown, an installation shaft 41 is fixedly installed inside the vessel body 1, and a gear 42 is rotatably installed on the surface of the installation shaft 41. The gear 42 includes a first tooth 421 and a second tooth 422, which are coaxially fixed. The first tooth 421 meshes with the connecting body 3, and the second tooth 422 meshes with a horizontal rack 52.
[0040] When the float 2 drives the connecting body 3 to move longitudinally, the teeth on the surface of the connecting body 3 drive the first tooth 421 to rotate around the mounting shaft 41. The first tooth 421 drives the second tooth 422 to rotate synchronously, thereby causing the second tooth 422 to drive the horizontal rack 52 and the baffle plate 51 to move horizontally to block or open the first liquid inlet 11.
[0041] When the float 2 drives the connecting body 3 to move longitudinally, the connecting body 3 drives the first gear 42 to rotate on the surface of the mounting shaft 41 through the teeth on its surface. This drives the second tooth 422, which is fixed on the same axis, to rotate and drive the horizontal rack 52 and the baffle plate 51 to move horizontally. This drives the baffle plate 51 to move horizontally to block or open the first liquid inlet 11. This allows the feeding to be controlled according to the liquid level in the vessel 1, thereby achieving automatic feeding and ensuring the stability of the liquid level in the vessel 1.
[0042] like Figure 2 and3 As shown, an auxiliary rod 7 is fixedly installed on the inner wall of the top of the vessel body 1, and the float 2 is slidably mounted on the surface of the auxiliary rod 7. The auxiliary rod 7 enables the float 2 to move stably longitudinally, acting as a guide rail for the float 2. It should be noted that the outer circumference of the float 2 can also fit against the inner wall of the vessel body 1, thus eliminating the need for installing the auxiliary rod 7.
[0043] The float 2 is rotatably mounted on its outer circumference. When the outer circumference of the float 2 moves longitudinally against the inner wall of the vessel 1, the ball bearings can rotate within the inner wall of the vessel 1, thereby reducing the resistance during the longitudinal movement of the float 2 and facilitating its longitudinal movement.
[0044] The length of the auxiliary rod 7 is less than the height of the vessel body 1. A limiting body 71 is fixedly installed at the lower end of the auxiliary rod 7, and a side stirring assembly 8 is rotatably installed inside the auxiliary rod 7. The limiting body 71 can limit the float 2 to prevent it from detaching from the auxiliary rod 7. The side stirring assembly 8 includes a side drive body 81 and a side stirring body 82. The side drive body 81 is fixedly installed on the outside of the top of the vessel body 1, and the side stirring body 82, which is fixedly connected to the side drive body 81, is rotatably installed inside the auxiliary rod 7. When the scale inhibitor is continuously produced and the stirring structure 6 at the axial center is stirring, the side drive body 81 drives the side stirring body 82 to rotate. Thus, during the rotation at the axial center, the eccentric side stirring body 82 can synchronously rotate and stir, thereby improving the reaction effect.
[0045] The continuous production and automatic feeding process in this embodiment of the disclosure is as follows:
[0046] During the continuous production of scale inhibitor, the raw material processed in the reactor 1 flows out through the outlet 12, while the raw material enters through the first inlet 11, thus achieving dynamic equilibrium and continuous feeding.
[0047] During the process of raw materials being discharged from the outlet 12 and maintaining a stable liquid level in the vessel body 1, when the liquid level drops due to the discharge of raw materials, the float 2 moves synchronously downward along the surface of the auxiliary rod 7. At the same time, the float 2 reduces the moving resistance through the ball bearings, thereby driving the connecting body 3 to move downward and driving the first tooth 421 to rotate around the mounting shaft 41 through the teeth on the surface of the connecting body 3. When the first tooth 421 rotates, it drives the second tooth 422 to rotate synchronously, thereby causing the second tooth 422 to drive the horizontal rack 52 and the baffle plate 51 to move horizontally to block or open the first liquid inlet 11.
[0048] During the continuous production of the scale inhibitor, the limiting body 71 can limit the float 2 to prevent it from detaching from the auxiliary rod 7. When the scale inhibitor is produced continuously and the stirring structure 6 at the shaft center is stirring, the side drive body 81 drives the side stirring body 82 to rotate. Thus, during the rotation at the shaft center, the eccentric side stirring body 82 can rotate and stir synchronously, thereby improving the reaction effect.
[0049] After the liquid level in the vessel 1 is restored by feeding into the first inlet 11, the float 2 drives the connecting body 3 to move upward and drives the transmission body 4 and the blocking body 5 to block the first inlet 11 to stop feeding, thereby maintaining the stability of the liquid level in the vessel 1.
[0050] Example 2: As Figure 4 As shown, a second liquid inlet 13 is provided at the top of the vessel body 1 adjacent to the first liquid inlet 11. An installation shaft 41 is rotatably installed inside the vessel body 1. A gear 42 is fixedly installed on the surface of the installation shaft 41. The gear 42 includes a first tooth 421, a second tooth 422, and a third tooth 423 that are coaxially fixed. The connecting body 3 meshes with the first tooth 421. The blocking body 5 below the first liquid inlet 11 and the second liquid inlet 13 meshes with the second tooth 422 and the third tooth 423, respectively.
[0051] When the float 2 drives the connecting body 3 to move longitudinally, it drives the first tooth 421 to rotate. The rotation of the first tooth 421 drives the second tooth 422 and the third tooth 423 to rotate synchronously, thereby synchronously driving the two horizontal racks 52 and the baffle plate 51 below the first liquid inlet 11 and the second liquid inlet 13 to move horizontally, thereby synchronously blocking or opening the first liquid inlet 11 and the second liquid inlet 13, so that different raw materials can be automatically fed or stopped synchronously.
[0052] Example 3: As Figure 5 As shown, two sets of the first liquid inlet 11, the transmission body 4, and the blocking body 5 are symmetrically installed along the axis of the vessel body 1.
[0053] The two first liquid inlets 11 can input different raw materials, so that when the float 2 drives the connecting body 3 to move longitudinally, it can synchronously drive the first teeth 421 on both sides to rotate and drive the second teeth 422 to rotate. Thus, the second teeth 422 on both sides drive the horizontal racks 52 and the blocking bodies 5 on both sides to move horizontally, and then the blocking bodies 5 on both sides move horizontally to block or open the two first liquid inlets 11 respectively.
[0054] It should be noted that the gear ratio 42 of the two sets of transmission bodies 4 can also be set according to the feeding ratio of different raw materials, thereby controlling the feeding ratio based on the gear ratio 42. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
