Description

Technical Field

[0001] This utility model relates to the technical field of titanium gypsum preparation equipment, specifically a titanium gypsum pulping tank. Background Technology

[0002] Titanium gypsum is a precipitate primarily composed of calcium sulfate dihydrate, produced during the sulfuric acid process for titanium dioxide production. It is formed by adding alkaline substances such as limestone, lime, and carbide slag to neutralize acidic wastewater. Besides calcium sulfate dihydrate, titanium gypsum also contains iron and silicon, and its color ranges from green, yellow, to reddish-yellow. Through a series of processing steps, titanium gypsum can be transformed into useful materials such as plaster, gypsum board, and gypsum products. Titanium gypsum slurry preparation is a crucial step in the process, typically involving mixing titanium gypsum with water to form a gypsum slurry. This slurry can be used to manufacture gypsum building materials, as well as as a cement retarder and soil conditioner. Titanium gypsum, used in agents, composite binders, etc., has a free water content of about 40% and is hydrophilic, making it prone to clumping during storage. Currently, there are some problems in the titanium gypsum pulping process. Current pulping equipment lacks a self-cleaning function, causing significant difficulties in restarting the equipment when the pulping tank is not in use, as the residual titanium gypsum slurry solidifies. Furthermore, the current equipment has low utilization of clumped raw materials; during subsequent filtration and screening of the titanium gypsum slurry, this unmixed and clumped raw material is directly removed, making it impossible to effectively utilize this material. Therefore, further improvements to the current pulping equipment are needed. Utility Model Content

[0003] To address the above technical problems, this utility model provides a titanium gypsum pulping tank.

[0004] To solve the above-mentioned technical problems, this utility model provides a titanium gypsum pulping tank, including a tank body. A feed hopper is fixedly connected to the top of the tank body, and a discharge valve and support legs are fixedly connected to the bottom of the tank body. A motor is connected to the top of the tank body, and the output end of the motor passes through the top of the tank body and is fixedly connected to a main shaft. A stirring blade is fixedly connected to the surface of the main shaft. The stirring blade is a spiral stirring blade. A crushing roller is fixedly connected to the bottom of the main shaft. The crushing roller has a protrusion on its lower part to facilitate the crushing of agglomerated titanium gypsum. A scraper is also fixedly connected to the main shaft through a connecting rod. The scraper abuts against the inner wall of the tank body. A spray pipe is also fixedly connected to the upper part of the tank body. A spray head is fixedly connected to the bottom of the spray pipe. The water inlet end of the spray pipe passes through the side wall of the tank body and is equipped with a valve. The spray pipe is located above the scraper. A perforated plate is fixedly connected to the bottom of the tank body. The top of the perforated plate abuts against the crushing roller.

[0005] Furthermore, a cleaning door is hinged to the side wall of the tank, and the cleaning door is located between the orifice plate and the scraper.

[0006] Furthermore, the motor is fixedly connected to the top of the tank via a mounting bracket.

[0007] Furthermore, the spray pipe is annular and conforms to the shape of the inner wall of the tank.

[0008] Furthermore, the interior of the tank has a recessed structure, with the unloading valve installed at the lowest point.

[0009] This utility model has the following advantages compared with the prior art:

[0010] This invention adds a scraper inside the pulping tank, which acts as a stirrer during pulping and scrapes off the pulp adhering to the tank wall during unloading. By changing the water inlet to a ring-shaped spray pipe, the device inside the tank can be sprayed and rinsed after unloading if the pulping tank is not in use, preventing residual pulp from solidifying and affecting reuse. By installing a perforated plate and a crushing roller at the bottom, titanium gypsum clumps deposited at the bottom can be broken up during pulping, promoting the mixing of titanium gypsum and water into a pulp, thus improving raw material utilization. For clumps that cannot be broken, the cleaning door can be opened periodically for cleaning. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figures 1 to 2The titanium gypsum pulping tank shown includes a tank body 1. A feed hopper 2 is fixedly connected to the top of the tank body 1, a discharge valve 3 is fixedly connected to the bottom, and support legs 15 are also fixedly connected. A motor 4 is connected to the top of the tank body 1. The output end of the motor 4 passes through the top of the tank body 1 and is fixedly connected to a main shaft 5. A stirring blade 6, which is a spiral stirring blade, is fixedly connected to the surface of the main shaft 5. A crushing roller 12 is fixedly connected to the bottom of the main shaft 5. The lower part of the crushing roller 12 has a raised structure to facilitate the crushing of agglomerated titanium gypsum. A scraper 10 is also fixedly connected to the main shaft 5 via a connecting rod 11. Plate 10 abuts against the inner wall of tank 1. A spray pipe 7 is fixedly connected to the upper part of tank 1. A spray head 8 is fixedly connected to the bottom of spray pipe 7. The water inlet end of spray pipe 7 passes through the side wall of tank 1 and is equipped with a valve 9. The water inlet end is connected to a water source. Spray pipe 7 is located above scraper 10. A perforated plate 13 is fixedly connected to the lower part of tank 1. The top of perforated plate 13 abuts against crushing roller 13. Perforated plate 13 can perform preliminary filtration of titanium gypsum slurry to prevent large lumps of titanium gypsum from entering the next process. Perforated plate 13 and crushing roller 12 work together to crush titanium gypsum blocks.

[0016] In order to remove unbroken clumps in a timely manner, a cleaning door 14 is hinged to the side wall of the tank body 1, and the cleaning door 14 is located between the orifice plate 13 and the scraper 10.

[0017] To increase the stability of the connection, the motor 4 is fixedly connected to the top of the tank 1 via the mounting bracket 16.

[0018] To facilitate rinsing of the tank wall, the spray pipe 7 is annular and conforms to the inner wall of the tank 1.

[0019] To facilitate the discharge of titanium gypsum slurry, the interior of tank 1 has a recessed structure, and the discharge valve 3 is installed at the lowest point.

[0020] The working process of this embodiment is as follows:

[0021] Titanium gypsum is added to tank 1 through feed hopper 2. Then, motor 4 is started and valve 9 is opened to stir and slurry the titanium gypsum. After adding a certain amount of water, valve 9 is closed, and stirring and slurrying continue using stirring blades 6 and scraper 10. During this process, crushing roller 12 and perforated plate 13 work together to crush the titanium gypsum lumps deposited at the bottom, improving the utilization rate of raw materials. After slurrying is completed, discharge valve 3 is opened to discharge the titanium gypsum slurry to the next process. At this time, perforated plate 13 acts as a filter, removing any uncrushed titanium gypsum. After the material is screened out, it can be cleaned through the cleaning door 14. During the discharge, the motor 4 continuously drives the scraper 10 to clean the inner wall of the tank 1 to prevent the tank wall from having any residual titanium gypsum slurry. After the discharge is completed, the discharge valve 3 can be closed and the material can be added again for pulping. If you want to suspend the use of the pulping equipment for a period of time, you can start the motor 4 to drive the scraper 10 to clean the tank wall, and at the same time open the valve 9 to rinse the inner wall of the tank 1 to prevent the residual titanium gypsum slurry from solidifying and affecting the restart of the equipment.
