Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically to a mixing device for the sustained release of neutralizing agents. Background Technology

[0002] Neutralization is the process by which an acid (acidic salt) and a base (basic salt) interact to adjust the pH value to around neutral. Chemicals used to treat acidic and alkaline substances are called neutralizing agents. This is crucial in many chemical and industrial processes. For example, in water treatment, neutralizing agents can be used to adjust the pH value of water to prevent pipe corrosion or meet specific water quality requirements. Sustained-release neutralizing agents are a process that uses special formulation technology to slowly release the neutralizing agent over a certain period of time to achieve a long-lasting effect.

[0003] When a neutralizing agent is released in a slow-release manner, various raw materials need to be mixed to achieve the slow release of the neutralizing agent. However, the mixing devices used in the prior art for the slow release of neutralizing agents often use a fixed mixing tank with rotating blades to achieve the mixing function, resulting in many dead zones inside the mixing tank during the mixing process. Moreover, the existing mixing devices add all raw materials into the mixing tank together for mixing, resulting in poor mixing uniformity and mixing efficiency. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a mixing device for the sustained release of neutralizing agents.

[0005] The technical solution of this utility model is: a mixing device for the sustained release of a neutralizing agent, comprising a mixing cylinder, several raw material boxes equally distributed at the top of the mixing cylinder, a mixing component disposed inside the mixing cylinder, and a drive motor disposed at the top of the mixing cylinder and providing power to the mixing component;

[0006] Each raw material box is equipped with a discharge pipe that runs through the mixing cylinder at the bottom;

[0007] The mixing assembly includes an installation sleeve fixedly installed at the top of the mixing cylinder and connected to each discharge pipe, an extrusion screw rotatably engaged inside the installation sleeve, and a mixing paddle installed at the bottom of the installation sleeve; several discharge nozzles are evenly distributed on the outer wall of the installation sleeve; a vertical shaft is installed through the extrusion screw; and the mixing paddle is fixedly connected to the bottom of the vertical shaft.

[0008] The output end of the drive motor is fixedly connected to the top of the vertical shaft.

[0009] Furthermore, each discharge pipe is slidably fitted with a sealing plate, and the sealing plate has a through hole that communicates with the discharge pipe. A wedge-shaped seat is provided at the end of the sealing plate near the mounting sleeve. A return spring is fitted onto the discharge pipe and abuts against the side wall of the sealing plate. A connecting sleeve is rotatably fitted onto the outside of the mounting sleeve. A push rod that abuts against the wedge-shaped seat is provided on the outer wall of the connecting sleeve. An internal gear ring is fitted inside the connecting sleeve. A linkage shaft is rotatably fitted onto the top of the mixing cylinder. A first gear that meshes with the internal gear ring is provided at the bottom of the linkage shaft. A second gear is provided at the top of the linkage shaft. A drive gear plate that meshes with the second gear is fitted onto the vertical shaft. A housing located outside the drive motor is provided at the top of the mixing cylinder.

[0010] Explanation: During the rotation of the vertical shaft, the meshing action of the drive gear and the second gear drives the vertical shaft to rotate. The meshing action of the first gear and the internal gear ring drives the connecting sleeve and the push rod to rotate. The push rod continuously collides with each closed plate. At this time, the through holes on the closed plate are connected to the corresponding material drop pipe, so that the raw materials inside each raw material box can intermittently enter the installation sleeve, avoiding the concentrated falling of raw materials and causing insufficient mixing.

[0011] Furthermore, a rubber wheel is rotatably engaged at the end of the push rod away from the connecting sleeve;

[0012] Note: By setting up a rubber roller, the vibration of the device caused by the collision between the rubber roller and the wedge seat can be reduced, which helps to improve the operational stability of the device.

[0013] Furthermore, the mixing cylinder includes a first cylinder and a second cylinder that is movably latched to the bottom end of the first cylinder; a base is movably latched to the bottom end of the second cylinder; and an electric push rod connected to the outer wall of the first cylinder is provided on the base.

[0014] Note: By setting up a split mixing cylinder, it is beneficial to improve the convenience of transferring the mixed materials.

[0015] Furthermore, a filter disc is fitted inside the mixing cylinder between the mounting sleeve and the mixing paddle; a material feeding disc is fitted on the vertical shaft to abut against the upper end face of the filter disc;

[0016] Note: By setting up a filter plate and a feeding plate, the raw materials can be filtered before mixing, which helps to improve the effect of the neutralizing agent during slow release.

[0017] The working principle of this utility model is as follows:

[0018] The raw materials required for the slow release of the neutralizing agent are added into each raw material box. Each raw material enters the installation sleeve through the discharge pipe. The drive motor drives the vertical shaft and the extrusion screw to rotate, so that the various raw materials are discharged through the discharge nozzle under the action of the extrusion screw, completing the pre-mixing. Then, the mixing paddle is used to mix the various raw materials a second time. At the same time, during the rotation of the vertical shaft, the meshing action of the drive gear and the second gear drives the vertical shaft to rotate. The meshing action of the first gear and the internal gear ring drives the connecting sleeve and the push rod to rotate. The push rod continuously collides with each closed plate. At this time, the through holes on the closed plate are connected to the corresponding discharge pipe, so that the raw materials in each raw material box can intermittently enter the installation sleeve.

[0019] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects:

[0020] First, the structure of this utility model is reasonably designed. It can use a rotating extrusion screw to extrude and mix various raw materials during the slow release of the neutralizer for pretreatment. Then, it uses a mixing paddle to mix the premixed material for a second time, which improves the mixing uniformity and mixing efficiency during the slow release of the neutralizer.

[0021] Secondly, this utility model utilizes the intermittent collision between the push rod and the closed plate to allow each raw material to intermittently enter the installation sleeve through the corresponding discharge pipe for extrusion and mixing, thereby avoiding concentrated falling of raw materials and promoting the uniformity of mixing.

[0022] Third, this utility model utilizes a rotating feed plate above the filter plate to filter the premixed raw materials, which can effectively remove impurity particles from the raw materials and improve the effect of the neutralizing agent during slow release. Attached Figure Description
