Description

Technical Field

[0001] The utility model relates to the technical field of glass-lined agitators, in particular to a glass-lined agitator with a secondary stirring structure. Background Art

[0002] Glass lining is made by applying porcelain glaze with a high silicon content on the metal surface and firing it at 950 °C, so that the porcelain glaze adheres closely to the surface of the metal iron tire. It is widely applicable to industrial production such as chemical industry, medicine, dyes, pesticides, organic synthesis, petroleum, food manufacturing and national defense industry, and has the dual advantages of chemical stability similar to glass and metal strength. A glass-lined agitator is an agitator made of glass-lined material.

[0003] An existing glass-lined agitator with a secondary stirring structure (publication number: CN217221147U) has at least the following disadvantages: The device can initially mix and stir the materials by setting stirring blades, and then filter the materials through a filter plate and then perform secondary stirring through spiral blades to prevent blockage problems during feeding caused by uneven mixing of materials and the generation of precipitates. However, when quantitative mixing of materials is required, due to the influence of gravity, particulate materials will gradually sink to the lower layer of the materials during the mixing process. When the solubility of the lower-layer materials is saturated, precipitates of the materials will appear. At this time, the upper-layer materials are not yet saturated. If the precipitated materials are filtered out by the filter plate at this time, the mixing ratio of the materials will be inconsistent with the expectation, resulting in poor mixing effect of the materials. Therefore, this utility model is proposed. Summary of the Utility Model

[0004] The purpose of this utility model is to solve the deficiencies existing in the prior art, and to propose a glass-lined agitator with a secondary stirring structure.

[0005] In order to achieve the above purpose, this utility model adopts the following technical scheme:

[0006] A glass-lined agitator with a secondary stirring structure includes a stirring tank. A motor is fixed on the top surface of the stirring tank, and the output shaft of the motor extends into the interior of the stirring tank. A stirring assembly is arranged inside the stirring tank. The stirring assembly includes a three-stage telescopic rod fixed on the output shaft of the motor, and three stirring blades are fixed on the outer wall of the three-stage telescopic rod.

[0007] As a further scheme of this utility model, a support plate is fixed on the inner wall of the stirring tank. An installation groove is opened on the top surface of the support plate, a one-way bearing is fixed inside the installation groove, a reciprocating lead screw is fixed on the inner ring of the one-way bearing, a screw joint is fixed at the bottom end of the three-stage telescopic rod, the screw joint is threadedly connected with the reciprocating lead screw, and an installation frame is arranged on the outer wall of the three-stage telescopic rod, and a filter net is fixed inside the installation frame.

[0008] As a further solution of the present utility model, a scraping strip is fixed on the outer wall of the mounting frame, and the scraping strip is in close fit with the inner wall of the mixing tank.

[0009] As a further solution of the present utility model, the mounting frame is rotationally connected to the outer wall of the three-stage telescopic rod through a bearing. Two limiting rods are fixed inside the mixing tank, and two limiting grooves are formed on the outer wall of the mounting frame. The limiting rods are slidably arranged inside the limiting grooves.

[0010] As a further solution of the present utility model, a feeding pipe is communicated with and fixed to the top surface of the mixing tank. The inner bottom surface of the mixing tank is of a funnel-shaped structure, and an electromagnetic discharging valve is communicated and fixed to the bottom surface of the mixing tank.

[0011] As a further solution of the present utility model, the length of the reciprocating lead screw is two-thirds of the depth of the inner cavity of the mixing tank, and the length of the reciprocating lead screw is also less than the maximum telescopic stroke of the three-stage telescopic rod.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] By setting the three-stage telescopic rod as the main shaft of the stirrer, and then threading the reciprocating lead screw connected by a one-way bearing with the screw joint at the bottom end of the three-stage telescopic rod, when the three-stage telescopic rod rotates clockwise forward, it continuously drives the stirring blades to mix and stir the materials inside the mixing tank, so that the materials are preliminarily mixed. After the materials are mixed, due to the local saturation of the lower layer of the materials, when there are precipitated materials in the lower layer of the materials, the three-stage telescopic rod rotates counterclockwise in the reverse direction, so that the reciprocating lead screw drives the three-stage telescopic rod to continuously expand and contract, so that the filter screen lifts the precipitate and moves back and forth between the upper and lower layers of the materials, so that the precipitated materials are fully mixed with the unsaturated materials in the upper layer, thus completing the secondary mixing and stirring of the materials, effectively avoiding the problem that when quantitatively mixing materials, the mixing ratio of the materials is inconsistent with the expectation due to filtering out the precipitated materials, resulting in poor mixing effect of the materials.

[0022] As Figures 1-4 shown, an enamel stirrer with a secondary stirring structure includes a stirring tank 1. A motor 101 is fixed on the top surface of the stirring tank 1. The output shaft of the motor 101 extends into the interior of the stirring tank 1. A stirring assembly is arranged inside the stirring tank 1. The stirring assembly includes a three-stage telescopic rod 2 fixed on the output shaft of the motor 101, and three stirring blades 201 are fixed on the outer wall of the three-stage telescopic rod 2.

[0023] As Figures 2-4As shown in the figure, in this embodiment, a support plate 202 is fixed to the inner wall of the stirring tank 1. An installation groove 203 is formed in the top surface of the support plate 202. A one-way bearing 204 is fixed inside the installation groove 203. A reciprocating lead screw 205 is fixed to the inner ring of the one-way bearing 204. A screw joint 206 is fixed to the bottom end of the three-stage telescopic rod 2. The screw joint 206 is threadedly connected to the reciprocating lead screw 205. An installation frame 207 is arranged on the outer wall of the three-stage telescopic rod 2. A filter screen 208 is fixed inside the installation frame 207. By setting the three-stage telescopic rod 2 as the main shaft of the stirrer and then threadedly connecting the reciprocating lead screw 205 connected by the one-way bearing 204 to the screw joint 206 at the bottom end of the three-stage telescopic rod 2, when the three-stage telescopic rod 2 rotates clockwise in the forward direction, the stirring blades 201 are continuously driven to mix and stir the materials inside the stirring tank 1, so that the materials are preliminarily mixed. When the materials are mixed, due to the local saturation of the lower layer of the materials, resulting in precipitated materials in the lower layer of the materials, the three-stage telescopic rod 2 rotates counterclockwise in the reverse direction, so that the reciprocating lead screw 205 drives the three-stage telescopic rod 2 to continuously expand and contract, so that the filter screen 208 lifts the precipitate and moves back and forth between the upper and lower layers of the materials, so that the precipitated materials are fully mixed with the unsaturated materials in the upper layer, thereby completing the secondary mixing and stirring of the materials, effectively avoiding the problem that when quantitatively mixing materials, the mixing ratio of the materials is inconsistent with the expectation due to filtering out the precipitated materials, resulting in poor mixing effect of the materials.

[0024] As Figures 2-4 shown, in this embodiment, a scraping strip 3 is fixed to the outer wall of the installation frame 207. The scraping strip 3 is in close contact with the inner wall of the stirring tank 1. By setting the scraping strip 3, the scraping strip 3 can be driven to scrape the stirring tank 1 during the up and down movement of the installation frame 207, and the granular materials attached to the inner wall of the stirring tank 1 are scraped off, ensuring the mixing effect of the materials.

[0025] As Figures 2-4 shown, in this embodiment, the installation frame 207 is rotatably connected to the outer wall of the three-stage telescopic rod 2 through a bearing. Two limiting rods 4 are fixed inside the stirring tank 1. Two limiting grooves 401 are formed in the outer wall of the installation frame 207. The limiting rods 4 are slidably arranged inside the limiting grooves 401. By setting the installation frame 207 to be rotatably connected to the outer wall of the three-stage telescopic rod 2 and then setting the limiting rods 4 to slide inside the limiting grooves 401, a limiting effect can be exerted on the installation frame 207, and the installation frame 207 can be prevented from rotating together with the three-stage telescopic rod 2, resulting in excessive friction between the scraping strip 3 and the inner wall of the stirring tank 1, and reducing the service life of the scraping strip 3 and the stirring tank 1.

[0026] As Figures 2-4As shown in the figure, in this embodiment, the top surface of the mixing tank 1 is connected and fixed with a feeding pipe 5. The inner bottom surface of the mixing tank 1 is of a funnel-shaped structure. The bottom surface of the mixing tank 1 is connected and fixed with an electromagnetic discharging valve. Through the feeding pipe 5, the materials to be mixed can be added into the mixing tank 1, and through the electromagnetic discharging valve, the mixed materials can be discharged from the mixing tank 1.

[0027] As Figures 2-4 shown in the figure, in this embodiment, the length of the reciprocating lead screw 205 is two-thirds of the depth of the inner cavity of the mixing tank 1, and the length of the reciprocating lead screw 205 is also less than the maximum telescopic stroke of the three-stage telescopic rod 2. By setting the length of the reciprocating lead screw 205 to be two-thirds of the depth of the inner cavity of the mixing tank 1, it is ensured that the filter screen 208 can lift the precipitated materials to the upper layer of the materials for mixing and stirring, ensuring the mixing effect of the materials. By the fact that the length of the reciprocating lead screw 205 is also less than the maximum telescopic stroke of the three-stage telescopic rod 2, it is prevented that the movement of the screw joint 206 is restricted by the three-stage telescopic rod 2, resulting in the inability of the screw joint 206 to perform reciprocating motion.

[0028] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: During use, the feeding pipe 5 adds the materials to be stirred and mixed into the interior of the stirring tank 1. Subsequently, the motor 101 is started to rotate clockwise forward, driving the three-stage telescopic rod 2 to rotate clockwise forward, and continuously driving the stirring blades 201 to mix and stir the materials inside the stirring tank 1, enabling the materials to be preliminarily mixed. During this process, the reciprocating lead screw 205 rotates together with the three-stage telescopic rod 2 due to the one-way bearing 204. Subsequently, after the materials are mixed, when there is precipitation of materials in the lower layer of the materials due to local saturation in the lower layer of the materials, the motor 101 is started to rotate counterclockwise backward, driving the three-stage telescopic rod 2 to rotate counterclockwise backward. At this time, the reciprocating lead screw 205 no longer rotates together with the three-stage telescopic rod 2 due to the one-way bearing 204, causing the reciprocating lead screw 205 and the screw joint 206 to rotate relative to each other, enabling the screw joint 206 to move up and down on the outer wall of the reciprocating lead screw 205, thereby driving the three-stage telescopic rod 2 to continuously expand and contract, causing the filter screen 208 to lift the precipitate and move repeatedly between the upper and lower layers of the materials, enabling the precipitated materials to be fully mixed with the unsaturated materials in the upper layer, thus completing the secondary mixing and stirring of the materials. By providing the scraping strip 3, the scraping strip 3 can be driven to scrape the stirring tank 1 during the up and down movement of the mounting frame 207, scraping off the particulate materials adhering to the inner wall of the stirring tank 1 to ensure the mixing effect of the materials. By providing that the mounting frame 207 is rotatably connected to the outer wall of the three-stage telescopic rod 2 and further providing that the limiting rod 4 slides inside the limiting groove 401, a limiting effect can be exerted on the mounting frame 207, preventing the mounting frame 207 from rotating together with the three-stage telescopic rod 2, resulting in excessive friction between the scraping strip 3 and the inner wall of the stirring tank 1 and reducing the service life of the scraping strip 3 and the stirring tank 1. The materials to be stirred and mixed can be added into the interior of the stirring tank 1 through the feeding pipe 5, and the stirred and mixed materials can be discharged from the stirring tank 1 through the electromagnetic discharging valve. By providing that the length of the reciprocating lead screw 205 is two-thirds of the depth of the inner cavity of the stirring tank 1, it is ensured that the filter screen 208 can lift the precipitated materials to the upper layer of the materials for mixing and stirring, ensuring the mixing effect of the materials. Also, by providing that the length of the reciprocating lead screw 205 is less than the maximum telescopic stroke of the three-stage telescopic rod 2, it is prevented that the movement of the screw joint 206 is restricted by the three-stage telescopic rod 2, causing the screw joint 206 to be unable to perform reciprocating motion.
