[0023] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the following will combine the accompanying drawings and specific implementation modes to introduce and explain the slurry tank sealing device of the present utility model in detail.

[0024] Combined with Figure 1 、 Figure 2 As shown, the present utility model provides a sealing device for a slurry tank, which is used in the stirring and mixing production process of raw materials. The slurry tank sealing device includes structures such as a tank body 1, a tank top 2, a stirring bracket 3, and a feeding cover 4. The tank body 1 is a containing container, and the cavity of the tank body 1 is used to provide a space for raw material stirring. Among them, the top of the tank body 1 is used to put raw materials. After the raw materials are stirred inside the tank body 1, they are discharged from the discharge port at the bottom of the tank body 1. The tank body 1 generally has a cylindrical outer shape, and a structure that gradually shrinks downward is provided at its bottom so that the raw materials can be concentrated downward, and the discharge port is located at the narrowest position of the shrinkage. The tank body 1 is generally made of stainless steel material.

[0025] The top of the tank body 1 is used to support the tank top 2 and the feeding cover 4. The tank top 2 is fixed to the tank body 1, and the feeding cover 4 can be opened. After the feeding cover 4 is opened, raw materials can be put into the tank body 1. The tank top 2 is used to support and install the stirring bracket 3. A drive motor 31 is installed on the stirring bracket 3. The output shaft of the drive motor 31 is connected to the stirring shaft 32. The stirring shaft 32 extends downward into the inner cavity of the tank body 1. The drive motor 31 drives the stirring shaft 32 to rotate, and blades are installed on the stirring shaft 32 to stir the raw materials through the blades.

[0026] An annular tank body gasket is provided at the contact positions between the tank body 1, the tank top 2, and the feeding cover 4. Specifically, a support plane with a certain width is provided at the top of the tank body 1, and the shape of the tank body gasket is consistent with the shape of the top edge of the tank body 1, which can ensure a stable support effect on the tank top 2 and the feeding cover 4. The stirring bracket 3 is installed on the tank top 2, and the tank top 2 can adopt a flat support structure to provide a stable support effect on the stirring bracket 3, so that the driving motor 31 is fixedly assembled; a bracket gasket is provided between the tank top 2 and the stirring bracket 3, which can seal the joint between the tank top 2 and the stirring bracket 3. A lid gasket is provided between the tank top 2 and the feeding cover 4. A part of the edge of the feeding cover 4 cooperates with the tank body 1, and the other part of the edge cooperates with the tank top 2. A part of the edge of the feeding cover 4 cooperates with the tank body 1 to jointly squeeze the tank body gasket, and the other part of the edge of the feeding cover 4 cooperates with the tank top 2 to jointly squeeze the lid gasket, where the lid gasket can be independent of the tank body gasket. Through the tank body gasket, the bracket gasket, and the lid gasket, the gaps between multiple parts such as the tank body 1 and the tank top 2, the tank body 1 and the feeding cover 4, and the tank top 2 and the stirring bracket 3 are sealed, so that the inner cavity of the tank body 1 is completely sealed and isolated from the outside world, and the raw materials in the tank body 1 can be stirred in a sealed space. The tank body gasket, the bracket gasket, and the lid gasket can all adopt Teflon gaskets.

[0027] An air inlet assembly 5 and an exhaust assembly 6 are provided on the tank top 2. The air inlet assembly 5 is connected to a gas source, and generally nitrogen is selected as the protective gas. The air inlet assembly 5 is used to convey the protective gas into the tank body 1. The retained gas enters the tank body 1, which can replace the air inside the tank body 1. The exhaust assembly 6 is used to discharge the gas, which can ensure that there is no air in the tank during stirring and production under completely isolated sealed conditions. Since the gaps where the structures of the tank body 1, the tank top 2, the stirring bracket 3, and the feeding cover 4 come into contact with each other are all sealed, the filled protective gas hardly leaks out from the gaps, so the consumption of the protective gas can be reduced and the economy is better.

[0028] Combined Figure 1 As shown, two feeding covers 4 are provided for the present utility model. The two feeding covers 4 are respectively located on both sides of the stirring bracket 3 and are generally symmetrically distributed about the center line, and the two feeding covers 4 can be opened to feed materials into the tank body 1 at the same time.

[0029] Combined Figure 2 , a folded edge 41 that turns up is provided at the straight edge of the feeding cover 4, which is used to form an overlapping area with the tank top 2 to clamp the lid gasket. As Figure 3As shown, the hem 41 is an inverted "V" - shaped structure. Similarly, an inverted "V" - shaped structure is also provided at the edge of the tank top 2. The two inverted "V" - shaped structures can squeeze each other and jointly press the material cover gasket A which is also in an inverted "V" - shaped structure. By setting the inverted "V" - shaped hem 41, it can play a certain positioning role. Compared with the plane sealing structure, the sealing performance is better.

[0030] Specifically, the feeding cover 4 of the present utility model can be removed from the tank body 1. The feeding cover 4 is pressed and fixed by the cover clamps 43 provided on the tank body 1 and the tank top 2, so as to achieve the fastening effect of the feeding cover 4. Figure 1 Combined with

[0031] Combined with Figure 2 As shown, the air inlet assembly 5 includes a pressure gauge 51, a pressure reducing valve 52, a flow meter 53, and stop valves 54. The pressure reducing valve 52 can play a role in regulating the conveying air pressure. The pressure gauge 51 detects the air pressure value in real - time. The flow meter 53 detects the air supply flow rate. Two stop valves 54 are provided, one at the head and one at the tail, which can respectively control the opening and closing of the pipeline. When maintenance is required, the two stop valves 54 can be closed simultaneously.

[0032] Combined with Figure 2 As shown, an alarm and pressure relief mechanism 7 is installed on the tank top 2. The alarm and pressure relief mechanism 7 is used to detect the air pressure inside the tank body 1. The alarm and pressure relief mechanism 7 displays the air pressure in the tank in real - time and has the functions of ultra - high pressure and ultra - low pressure alarm. Specifically, when the air pressure value exceeds the alarm set value, the system sends an over - pressure alarm; when the air pressure value reaches the safety pressure relief set value, the safety pressure relief valve automatically opens to achieve pressure relief; the pressure relief set value is greater than the alarm set value.

[0033] Based on any of the above - mentioned technical solutions and their combinations, an observation window 42 with a scraper inside is provided on the feeding cover 4 of the present utility model. The observation window 42 allows the operator to observe the stirring situation in the inner cavity of the tank body 1 from the outside, and the illumination is provided by the illuminating lamp 21 installed inside the tank top 2. The scraper can scrape the inner surface of the observation window 42 to prevent raw materials from adhering and affecting the observation.

[0034] Combined with Figure 1 As shown, a universal cleaning ball 22 is installed on the tank top 2 of the present utility model. The universal cleaning ball 22 can change the spraying angle and is used to spray water into the tank body 1. After the stirring is completed, the inside of the tank body 1 can be rinsed. The appropriate number of universal cleaning balls 22 can be installed according to the size of the tank body 1.

[0035] Add Mitflon gaskets at the joints between various components, which are wear-resistant, corrosion-resistant and have good sealing performance. Add a nitrogen inlet control device, an exhaust air pressure monitoring and feedback device, and a safety relief device to the tank top design. The nitrogen sealing transformation of the slurry tank is achieved by adjusting the flow rate and pressure of the inlet and outlet nitrogen. The transformation can be completed on-site with a short delivery period, fully meeting the usage requirements, with low transformation cost, simple operation and high safety. The exhaust assembly 6 can achieve functions of precise pressure control, air pressure feedback alarm and safety relief. Add an observation window, a lighting lamp and a universal cleaning ball to the tank top to realize the function of observing the materials in the tank and cleaning the equipment without dead angles.
