Description

Technical Field

[0001] This utility model relates to the field of starch storage tank technology, specifically a spray starch storage tank. Background Technology

[0002] Sprayed starch is a special interlayer reinforcing agent for paper and paperboard. It has good dispersibility in water and stable suspension, making it an effective additive for improving the interlayer bonding strength, stiffness, and ring crush strength of paperboard or thick paper. The refill system can utilize idle tanks or spare parts to transfer and deliver sprayed starch slurry, thereby adjusting the product structure and increasing production capacity.

[0003] Conventional spray starch storage tanks are prone to starch deposition and caking during use, and the liquid level is difficult to monitor. This can easily lead to insufficient or overflowing of the spray starch slurry, or difficulty in pumping it out, affecting production. They have poor reliability and ease of use. Therefore, we propose a spray starch storage tank. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides an improved version of a starch spraying storage tank. Please refer to [link / reference]. Figures 1 to 3 The system includes: a base 1, a tank 2 connected to the upper end of the base 1, a sealing ring 3 welded to the connection between the base 1 and the tank 2, a tank cover 4 fixed to the upper end of the tank 2, the tank cover 4 forming a sealing structure with the base 1 through the tank 2 and the sealing ring 3, a motor 5 bolted to the upper surface of the middle part of the tank cover 4, a stirring shaft 6 connected to the output shaft of the motor 5, the stirring shaft 6 passing through the inner side of the base 1 and the tank 2 through a sealed bearing, and the stirring shaft 6 forming a rotatable connection with the base 1 through the output shaft of the motor 5, a paddle-shaped stirring blade 7 fixed to the outer wall of the stirring shaft 6, and the stirring blade 7 and the scraper 8 forming a sealing structure with the tank 2 through the stirring shaft 6 and the output shaft of the motor 5. The stirring shaft 6 is rotatably connected to the outer wall of the end near the base 1, and a scraper 8 is fixed thereon. The lower end face of the scraper 8 is in close contact with the inner surface of the base 1. The scraper 8 is used to prevent the sprayed starch from adhering to the inner surface of the base 1 and being unable to be extracted. The stirring blade 7 and the scraper 8 are used to stir the sprayed starch in the tank 2 and the inner side of the base 1 through the output shaft of the motor 5 and the stirring shaft 6, so as to prevent the sprayed starch from settling and affecting the spraying quality after extraction. A suction pipe 9 is connected to the upper surface of one side of the tank cover 4. The suction pipe 9 is connected to the tank 2, and the suction pipe 9 is not in contact with the stirring blade 7. The suction pipe 9 is designed to facilitate the extraction of the collected sprayed starch from the storage tank.

[0022] Please see Figure 2 A sprayed starch storage tank includes: a metal outer shell 201 on the outermost layer of the tank body 2; a polyethylene threaded inner liner 202 passing through the inner side of the outer shell 201; the central axis of the threaded inner liner 202 coincides with that of the outer shell 201; the upper surfaces of the threaded inner liner 202 and the outer shell 201 are flush; and the lower end of the threaded inner liner 202 is slightly longer than the lower end of the outer shell 201. The threaded inner liner 202 facilitates the stirring of the sprayed starch by the rotation of the stirring blade 7, improving the flowability of the sprayed starch in the tank body 2 and reducing the adhesion of the sprayed starch to the threaded inner liner 202; and a resin filler 203 fills the gap between the outer shell 201 and the threaded inner liner 202. The resin filler 203 is used to improve the structural stability of the outer shell 201 and the threaded inner liner 202 and enhance the corrosion resistance and pressure resistance of the tank body 2.

[0023] Please see Figure 1 and Figure 4 A sprayed starch storage tank includes: a liquid level indicator cylinder 10 connected to the upper surface of the other side of the tank cover 4; a slot 11 is formed on the outer wall of one side of the liquid level indicator cylinder 10; a limiting ring 12 is fixed at the connection between the lower end of the liquid level indicator cylinder 10 and the tank cover 4; a through rod 13 is inserted through the inner side of the limiting ring 12; a float 14 is fixed at the lower end of the through rod 13; and the float 14 and the through rod 13 do not contact the stirring blade 7. The float 14 maintains its floating state on the surface of the sprayed starch due to its ultra-low density and the large contact area between its lower end and the upper surface of the sprayed starch. This is because the sprayed starch has a high surface tension and buoyancy. The near-pot-shaped float 14 prevents it from sinking into the sprayed starch during agitation. A colored indicator block 15 is fixed to the top of the rod 13, and the slot 11 matches the dimensions of the indicator block 15. The indicator block 15 is slidably connected to the liquid level indicator cylinder 10 via the rod 13 and the limiting ring 12. The liquid level indicator cylinder 10 can quickly identify the storage height of the sprayed starch in the tank 2 through the indicator block 15 and the rod 13, making it convenient for staff to replenish or remove the sprayed starch in a timely manner, preventing material overflow from affecting safety or insufficient material from affecting production efficiency.

[0024] Working principle: For this type of spray starch storage tank, when the spray starch storage tank is working, the motor 5 (model: YE3-100L2-4) drives the stirring shaft 6 to rotate through the output shaft. The motor 5 has a high protection level and a suitable working torque, which can stably stir the spray starch in a high temperature and high humidity environment. The paddle-shaped stirring blades 7 fixed on the stirring shaft 6 fully stir the starch slurry in the tank 2 to prevent sedimentation. The scraper 8 at the bottom of the stirring shaft 6 rotates close to the inner wall of the base 1 to remove the deposited starch. The tank 2 adopts a combination structure of outer shell 201 and threaded inner liner 202, with filler material 203 in the middle to enhance stability. The starch slurry is extracted through the suction pipe 9, and the liquid level is monitored by the liquid level indicator cylinder 10. The float 14 inside it floats up and down with the liquid level, driving the colored indicator block 15 at the top of the rod 13 to slide in the slot 11 to display the liquid level height. The entire system forms a sealed structure through the sealing connection ring 3 and the tank cover 4 to ensure the sealing performance of the storage tank.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
