Description

Technical Field

[0001] This utility model relates to the field of dry strength agent preparation technology, and in particular to a dry strength agent dispensing device. Background Technology

[0002] In paper mills, the addition of dry strength agents typically requires a continuous and stable supply of materials. Repackaged products are easier to integrate into the production line. Smaller packaging sizes better suit logistical needs, avoiding losses from collisions and leaks caused by large containers. This facilitates manual handling or mechanical loading and unloading, making it particularly suitable for small and medium-sized paper mills or short-distance transportation scenarios. Therefore, repackaging is necessary during the dry strength agent production process.

[0003] The dry strength agent liquid reagent is delivered into the housing of the device through the inlet pipe, completing the initial material supply. The reagent material is pre-treated by stirring equipment, and then precisely fed into the holding container through the dispensing mechanism to achieve quantitative dispensing of the material.

[0004] However, during the stirring and dispensing of reagent materials, strong shearing and softening effects are generated, entraining air into the materials. The air dissolved in the liquid precipitates and forms bubbles. These bubbles, trapped in the materials, hinder the full contact and mixing of liquid molecules, resulting in uneven distribution of the active ingredient in the dry strength agent in localized areas, thus affecting product quality. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where air bubbles are easily generated during material dispensing, and to propose a dry strength agent dispensing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dry strength agent dispensing device is designed, comprising a mixing shell, a dispensing mechanism fixedly installed at the lower end of the mixing shell, the dispensing mechanism being located above a conveyor belt, a container placed on the upper surface of the conveyor belt, a shell cover threaded onto the top of the mixing shell, a rotating shaft rotatably mounted on the top of the shell cover, a flow distribution box fixedly installed on the inner surface of the shell cover, a flow hole with multiple flow holes arranged in a circular array around the central axis of the flow distribution box, a liquid inlet pipe fixedly installed at the upper end of the shell cover, and an anchor-type stirrer fixedly installed at the bottom of the rotating shaft.

[0008] Preferably, a blade is fixedly installed on the outer side of the rotating shaft, and the blade is located above the anchor mixer.

[0009] Preferably, a fixing frame is fixedly installed on the outer side of the rotating shaft, and a baffle is fixedly installed on the upper surface of the fixing frame, with the upper surface of the baffle abutting against the bottom of the diversion box.

[0010] Preferably, the baffles are provided in multiple quantities and arranged in a circular array around the rotation axis.

[0011] Preferably, the interior of the retaining pad is made of a rubber structure.

[0012] Preferably, a scraper is fixedly installed on the outside of the rotating shaft, the end of the scraper is rotatably disposed inside the diversion box, and the outer edge of the scraper is in contact with the inner wall surface of the diversion box. The inside of the scraper is made of rubber.

[0013] Preferably, the dispensing mechanism includes a dispensing shell, a conveying pipe fixedly connected to the top of the dispensing shell, the conveying pipe being connected to the interior of the mixing shell through a pump body, an injection pipe fixedly connected to the lower end of the conveying pipe, the injection pipe being fixedly installed inside the lifting frame, and an electric telescopic rod fixedly installed on the upper surface of the lifting frame, the upper end of the electric telescopic rod being fixedly connected to the top of the dispensing shell.

[0014] Preferably, the length direction of the electric telescopic rod is parallel to the length direction of the injection tube, and both are vertically arranged.

[0015] The dry strength agent dispensing device proposed in this utility model has the following advantages: When the dry strength agent dispensing device is working, the material is first dispersed and flows out through the flow hole of the distribution box. Then, combined with the stirring action of the anchor mixer and the blade, the material is fully mixed. Furthermore, the stirring method of the anchor mixer and the blade can avoid the adverse effects of air bubbles on the material properties. The flow rate of the dispersed material is reduced, which further reduces the impact of the material and reduces the generation of air bubbles. Attached Figure Description

Detailed Implementation

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figure 1-4 A dry strength agent dispensing device includes a mixing shell 1, with a dispensing mechanism fixedly installed at the lower end of the mixing shell 1. The dispensing mechanism is used to dispense the dry strength agent that has been mixed inside the mixing shell 1. The dispensing mechanism is located above a conveyor belt 100, and a container 200 is placed on the upper surface of the conveyor belt 100. The container 200 is used to hold the dispensed dry strength agent. Both the dispensing mechanism and the conveyor belt 100 are existing structural equipment. The conveyor belt 100 delivers the container 200 to the area below the dispensing mechanism, and the dispensing mechanism can dispense the dry strength agent into the container 200.

[0023] The mixing shell 1 has a threaded cap 2 on top, which is easily disassembled to facilitate cleaning or replacement of the internal components. A rotating shaft 3 is rotatably mounted on the top of the cap 2, with a motor connected to its upper end. The motor is fixedly mounted on the top of the cap 2 via a base and drives the rotating shaft 3 to rotate. A distribution box 4 is fixedly mounted on the inner surface of the cap 2, with its central axis coinciding with the central axis of the rotating shaft 3. Multiple flow holes 6 are arranged in a circular array around the central axis of the distribution box 4 at its bottom. An inlet pipe 9 is fixedly mounted on the upper end of the cap 2, used to deliver the dry strength agent liquid material. The material flows directly into the distribution box 4 through the inlet pipe 9 and flows downward through the flow holes 6, dispersing the material and ensuring thorough mixing.

[0024] An anchor-type agitator 11 is fixedly installed at the bottom of the rotating shaft 3. When the rotating shaft 3 rotates, it drives the anchor-type agitator 11 to rotate, which further agitates the materials inside the mixing shell 1 and scrapes off the materials adhering to the inner wall surface of the shell. Compared with a turbine-shaped agitator, the anchor-type agitator 11 is less likely to generate bubbles, thus reducing the formation of bubbles inside the materials. A paddle 10 is fixedly installed on the outside of the rotating shaft 3, located above the anchor-type agitator 11. When the rotating shaft 3 rotates, it also drives the paddle 10 to rotate, which further agitates and mixes the materials, ensuring thorough mixing. Similar to the anchor-type agitator 11, the rotation of the paddle 10 also reduces the generation of bubbles.

[0025] A scraper 5 is fixedly installed on the outside of the rotating shaft 3. The end of the scraper 5 is rotatably set inside the diversion box 4, and the outer edge of the scraper 5 is in contact with the inner wall surface of the diversion box 4. The inside of the scraper 5 is made of rubber structure. When the rotating shaft 3 rotates, it can drive the scraper 5 to rotate. The rotation of the scraper 5 can scrape off the material attached to the inner wall surface of the diversion box 4, which can prevent the material from adhering to the inner wall surface of the diversion box 4.

[0026] Working principle: When the dry strength agent dispensing device is working, the material is sent into the shell through the liquid inlet pipe 9, and then the material enters the distribution box 4, allowing the material to flow out downward through the flow hole 6 in a dispersed state. At the same time, the motor is started to drive the rotating shaft 3 to rotate. The rotation of the rotating shaft 3 drives the anchor agitator 11 and the paddle 10 to rotate. The paddle 10 and the anchor agitator 11 can stir the material inside the shell, helping the material to be fully mixed. Compared with the turbine agitator, this stirring method can reduce the generation of bubbles. After the material inside the shell is mixed, it is sent into the container cylinder 200 through the dispensing mechanism. The container cylinder 200 is transported by the conveyor belt 100, thereby completing the dispensing work.

[0027] Example 2: Refer to Figure 1 and Figure 3 In another preferred embodiment of this utility model, based on embodiment 1, the dispensing mechanism includes a dispensing shell 16. A conveying pipe 12 is fixedly connected to the top of the dispensing shell 16. The conveying pipe 12 is connected to the interior of the mixing shell 1 through a pump body. The pump body delivers the material inside the mixing shell 1 into the conveying pipe 12. An injection pipe 13 is fixedly connected to the lower end of the conveying pipe 12. The conveying pipe 12 delivers the material into the injection pipe 13. The injection pipe 13 is fixedly installed inside the lifting frame 14. The material is injected into the container cylinder 200 through the injection pipe 13. An electric telescopic rod 15 is fixedly installed on the upper surface of the lifting frame 14. The upper end of the electric telescopic rod 15 is fixedly connected to the top of the dispensing shell 16. The length direction of the electric telescopic rod 15 is parallel to the length direction of the injection pipe 13 and both are vertically arranged. The electric telescopic rod 15 can drive the lifting frame 14 to move up and down, thereby adjusting the height of the material.

[0028] During the dispensing process, the empty container 200 is conveyed to the bottom of the injection tube 13 via the conveyor belt 100. The electric telescopic rod 15 is activated to move the lifting plate 14 downward. The downward movement of the lifting plate 14 moves the injection tube 13 downward, and the end of the injection tube 13 extends into the container 200 and is close to the bottom of the injection tube 13. Then, the pump body is activated to send the material inside the mixing shell 1 into the conveying pipe 12. The conveying pipe 12 injects the material into the container 200 through the injection tube 13. The distance between the injection tube 13 and the bottom of the conveying pipe 12 is small, which can avoid the material falling from a height and impacting the liquid surface, generating more bubbles. After the injection is completed, the electric telescopic rod 15 moves the lifting plate 14 upward, and the conveyor belt 100 can then send the filled container 200 out, while the empty container 200 is sent to the bottom of the injection tube 13, so that the cyclic dispensing work can be carried out.

[0029] Example 3: In Example 1, although the flow holes 6 are arranged in a circumferential array, the liquid inlet pipe 9 is located on one side of the cover 2. When the liquid inlet pipe 9 conveys material, more material permeates into the flow holes 6 closer to the liquid inlet pipe 9, while very little material permeates into the flow holes 6 farther from the liquid inlet pipe 9. This also causes uneven flow of material, affecting the mixing efficiency of the material. Therefore, this example is proposed. (Refer to...) Figure 1-4 In another preferred embodiment of this utility model, based on embodiment 1 or embodiment 2, a fixing frame 7 is fixedly installed on the outside of the rotating shaft 3. When the rotating shaft 3 rotates, it can drive the fixing frame 7 to rotate. A baffle 8 is fixedly installed on the upper surface of the fixing frame 7. When the fixing frame 7 rotates, it can drive the baffle 8 to rotate. The upper surface of the baffle 8 abuts against the bottom of the diversion box 4. Multiple baffles 8 are provided and arranged in a circumferential array around the rotating shaft 3. The inside of the baffle 8 is made of rubber structure. The baffle 8 abuts against the bottom of the diversion box 4 and can block the flow hole 6. The flow hole 6 in contact with the baffle 8 will be in a blocked state, and the material cannot flow down through the flow hole 6 here.

[0030] The distribution of the baffle 8 and the flow hole 6 is shown in the attached figure. Figure 1-2 As shown, the positions of the diversion box 4 and the flow hole 6 remain unchanged. The fixing frame 7 and the baffle 8 rotate with the rotation of the rotating shaft 3. During rotation, the baffle 8 continuously blocks the flow holes 6 at different positions, allowing material to pass through the flow holes 6 in turn. This enables the material to flow downwards more evenly, achieving an ideal dispersed state and facilitating rapid and thorough mixing. Furthermore, it reduces the flow velocity of the material, preventing excessive flow speed and turbulence, thus preventing air bubbles from being generated by material impact.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
