Technical Field

[0001] This utility model relates to the field of mixing tank technology, and in particular to an emulsion mixing tank. Background Technology

[0002] In the papermaking industry, papermaking additives play a crucial role in improving paper properties and increasing production efficiency. Emulsion-type papermaking additives are widely used in papermaking due to their unique properties and excellent application effects. The production of emulsion-type papermaking additives requires the use of an emulsion mixing tank.

[0003] In actual use, some raw materials of papermaking additives tend to adhere to the inner wall of the emulsion mixing tank used for producing papermaking additives. When cleaning the material adhering to the inner wall of the mixing tank, it is necessary to remove the top cover of the mixing tank and then manually scrape it off with tools, which reduces the convenience and maintenance efficiency of cleaning the adhering materials on the inner wall of the mixing tank. Utility Model Content

[0004] This utility model relates to an emulsion mixing tank. Through the arrangement of a scraping mechanism and an annular flushing pipe, when the inner wall of the mixing tank needs to be scraped and cleaned, the cleaning solvent is simply delivered to the annular flushing pipe via a delivery hose to flush the inner wall of the mixing tank. Then, the scraping mechanism rotates and scrapes away the material adhering to the inner wall of the mixing tank. The entire scraping and cleaning process does not require disassembling the top cover of the mixing tank, nor does it require manual scraping with tools, thus improving the convenience and maintenance efficiency of cleaning the inner wall of the mixing tank.

[0005] In a first aspect, this utility model provides an emulsion mixing tank, specifically comprising: a mixing tank body, a frame mounted on the top of the mixing tank body, a reducer mounted on the upper end of the frame, and a mixing motor mounted on the top of the reducer; a scraping mechanism provided at the bottom of the mixing tank body; an annular flushing pipe installed on the upper side inside the mixing tank body; the scraping mechanism includes a vertical rotating shaft, which is rotatably connected to the center of the bottom of the mixing tank body and penetrates through the bottom of the mixing tank body; a U-shaped scraper is fixedly connected to the upper end of the vertical rotating shaft, and a rubber scraper is provided on the outer side of the U-shaped scraper, the rubber scraper being in close contact with the inner wall of the mixing tank body; and a worm gear is fixedly installed at the lower end of the vertical rotating shaft.

[0006] Furthermore, the input shaft of the reducer is fixedly connected to the rotating shaft of the stirring motor, and the output shaft of the reducer is fixedly connected to the stirring shaft, with stirring blades provided on the outside of the stirring shaft.

[0007] Furthermore, a circular discharge hole is provided on the left side of the bottom end face of the mixing tank, and a discharge hopper is installed on the left side of the bottom end face of the mixing tank outside the circular discharge hole, with a valve installed at the lower end of the discharge hopper.

[0008] Furthermore, the scraping mechanism also includes a drive motor, which is fixedly installed at the bottom of the mixing tank, and a worm gear is installed on the shaft of the drive motor, and the worm gear meshes with a worm wheel.

[0009] Furthermore, the inlet of the annular flushing pipe penetrates the mixing tank, and the inlet of the annular flushing pipe is connected to a delivery hose; the annular flushing pipe is provided with spray heads in an annular array.

[0010] Furthermore, each of the spray nozzles has four protective rubber sheets attached in a circular array at the spray port, and each protective rubber sheet is fan-shaped.

[0011] This utility model provides an emulsion mixing tank, which has the following beneficial effects:

[0012] 1. With the scraping mechanism and annular flushing fitting, when the inner wall of the mixing tank needs to be scraped and cleaned, the cleaning solvent is simply delivered to the annular flushing fitting through the infusion hose to flush the inner wall of the mixing tank. Then, the drive motor is started, which rotates the U-shaped scraper. The U-shaped scraper, along with the rubber scraper, rotates and scrapes away the material adhering to the inner wall of the mixing tank. The entire scraping and cleaning process does not require disassembling the top cover of the mixing tank or using manual tools, greatly improving the convenience and maintenance efficiency of cleaning the adhering material on the inner wall of the mixing tank.

[0013] 2. Four protective rubber sheets are attached in a circular array at the spray nozzle of the spray head. When the spray head sprays cleaning solvent, the four protective rubber sheets will automatically open under the impact of the cleaning solvent. When the spray head stops spraying, the four protective rubber sheets will return to their initial position by their own elasticity, thus protecting the spray nozzle of the spray head again. This effectively reduces the chance of the spray head being blocked by debris. By preventing debris from entering, the maintenance cost of the spray head is effectively reduced.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1: Please refer to Figures 1 to 5 :

[0027] This utility model discloses an emulsion mixing tank, comprising: a mixing tank body 1, a frame 101 mounted on the top of the mixing tank body 1, a reducer 102 mounted on the upper end of the frame 101, and a stirring motor 103 mounted on the top of the reducer 102 for rotating the stirring shaft 107; a scraping mechanism 2 provided at the bottom of the mixing tank body 1; an annular flushing pipe 3 installed on the upper side inside the mixing tank body 1; the scraping mechanism 2 includes a vertical rotating shaft 201, which is rotatably connected to the center of the bottom of the mixing tank body 1 and passes through the bottom of the mixing tank body 1; a U-shaped scraper 205 is fixedly connected to the upper end of the vertical rotating shaft 201, and a rubber scraper 2 is provided on the outer side of the U-shaped scraper 205. 06. The rubber scraper 206 is in close contact with the inner wall of the mixing tank 1, thereby improving the scraping effect of the rubber scraper 206 on the attachments on the inner wall of the mixing tank 1 when the U-shaped scraper frame 205 rotates with the rubber scraper 206. A worm gear 204 is fixedly installed at the lower end of the vertical rotating shaft 201. The scraping mechanism 2 also includes a drive motor 202, which is fixedly installed at the bottom of the mixing tank 1. A worm 203 is installed on the rotating shaft of the drive motor 202, and the worm 203 meshes with the worm gear 204. With the setting of the scraping mechanism 2, the inner wall of the mixing tank 1 can be scraped and cleaned instead of manually, thereby improving the convenience of cleaning the attachments on the inner wall of the mixing tank 1.

[0028] The input shaft of the reducer 102 is fixedly connected to the rotating shaft of the stirring motor 103, and the output shaft of the reducer 102 is fixedly connected to the stirring shaft 107. The stirring shaft 107 is provided with stirring blades on the outside for stirring and mixing the raw materials of papermaking additives.

[0029] A circular discharge hole 104 is provided on the left side of the bottom end face of the mixing tank 1, and a discharge hopper 105 is installed outside the circular discharge hole 104 on the left side of the bottom end face of the mixing tank 1. A valve 106 is installed at the lower end of the discharge hopper 105 for discharging materials and cleaning solvents. The discharge hopper 105 is installed on the bottom end face of the mixing tank 1 by bolts. When it is necessary to clean the inside of the discharge hopper 105, the bolts on the discharge hopper 105 can be loosened and removed to clean the inner wall of the discharge hopper 105. Therefore, it can greatly improve the convenience of later maintenance of this emulsion mixing tank.

[0030] Example 2, based on Example 1, such as Figure 3 and Figure 5As shown, the inlet of the annular flushing pipe 3 penetrates the mixing tank 1, and the inlet of the annular flushing pipe 3 is connected to a delivery hose 301. The delivery hose 301 is connected to the outlet of the conveying equipment, which is used to deliver the cleaning solvent. The cleaning solvent can be an organic solvent. Depending on the composition of the papermaking additives, appropriate organic solvents can be selected for cleaning, such as ethanol, acetone, etc., which have good solubility for organic polymers such as resins and rubber. The annular flushing pipe 3 is provided with spray heads 302 in a ring array. Each spray head 302 has four pieces of [unspecified material] attached to its spray nozzle in a ring array. The protective rubber sheet 303 is fan-shaped, and the four protective rubber sheets 303 together form a complete circular protective structure. The four protective rubber sheets 303 are attached in a ring array at the spray nozzle of the spray head 302. When the spray head 302 sprays the cleaning solvent, the four protective rubber sheets 303 will automatically open under the impact force of the cleaning solvent. When the spray head 302 stops spraying, the four protective rubber sheets 303 will return to their initial position by their own elasticity, thus providing a shielding and protection function for the spray nozzle of the spray head 302.

[0031] The working principle of this embodiment is as follows: When in use, the stirring motor 103 is started first. The stirring motor 103 drives the output shaft of the reducer 102, the stirring shaft 107 and the stirring blade to rotate. Then, the raw materials of papermaking additives are added into the stirring tank 1. The materials are stirred and mixed by the rotating stirring blades. After mixing, the valve 106 is opened and the material is discharged through the discharge hopper 105.

[0032] When the inner wall of the mixing tank 1 needs to be scraped and cleaned, the cleaning solvent is delivered to the inside of the annular flushing fitting 3 through the infusion hose 301, and then sprayed out by the spray heads 302 arranged in a ring array on the annular flushing fitting 3. Finally, the solvent is sprayed onto the upper side of the inner circumference of the mixing tank 1. Under the action of gravity, the cleaning solvent flows downward and flushes the inner wall of the mixing tank 1. Then, the drive motor 202 is started, which rotates the worm gear 203, worm wheel 204, vertical rotating shaft 201 and U-shaped scraper 205. The U-shaped scraper 205, with rubber scraper 206, performs a rotating scraping operation on the inner wall of the mixing tank 1, thereby scraping off the material attached to the inner wall of the mixing tank 1. The cleaning solvent sprayed by the spray heads 302 further rinses the scraped material. Finally, the scraped material is discharged through the discharge hopper 105.
