[0027] like Figure 1 As shown, some embodiments of the present invention disclose a pulping and dispersing tank for handling solid lumpy water-containing materials. The aim is to provide a laboratory pulping and dispersing tank with a feeding and pulping device for solid lumpy water-containing materials, solving the problems of high labor intensity, low efficiency, uneven material crushing, and lack of specialized feeding and pretreatment devices in existing laboratory pulping and dispersing tanks when processing solid lumpy water-containing materials. This achieves efficient and uniform feeding and pulping of solid lumpy water-containing materials, improving experimental efficiency and the accuracy of results. The tank includes a pulping and dispersing tank body, with a feeding and pulping device for solid lumpy water-containing materials added to the top of the tank body, and a dispersing slurry connected to the bottom of the tank body, enabling continuous feeding and pulping of solid lumpy water-containing materials. The dispersing tank body is provided with an inlet and an outlet for adding water to adjust the concentration and for rinsing.

[0028] Specifically, it includes a tank body 1, a crushing mechanism, a pre-pulping mechanism, a pulping mechanism, and a screening mechanism 5; wherein, the tank body 1 includes, from top to bottom, a crushing chamber 3, a pre-pulping chamber 6, and a pulping chamber, and a feeding hopper 2 is also provided at the upper end of the tank body 1, and a material discharge port 10 is also provided at the bottom of the pulping chamber; the crushing roller 4 of the crushing mechanism is located in the crushing chamber 3 and directly below the feeding hopper 2, and is used to crush the material entering from the feeding hopper 2. The solid blocky water-containing material entering from the feeding hopper 2 first falls onto the crushing roller 4, the water will fall directly, the solid blocky material will be crushed by the crushing roller 4, and then continue to fall to the bottom of the crushing chamber 3; the pre-pulping mechanism is located in the pre-pulping chamber 6; the pulping mechanism is located in the pulping chamber; the screening mechanism 5 is located between the crushing mechanism and the pulping mechanism, and is used to screen the material processed by the crushing mechanism. The solid lumps crushed by the crushing roller 4 fall to the screening mechanism 5 for screening. Solid lumps that meet the size requirements fall from the screening mechanism 5 to the pre-pulping chamber 6 and are pre-pulped together with the falling water. After the pre-pulping is completed, the material enters the pulping chamber for pulping again. The pulping mechanism includes a main pulping agitator 12, which is vertically arranged in the pulping chamber. The material is dispersed under the rotation of the main pulping agitator 12, and finally a uniformly dispersed material is obtained.

[0029] This embodiment incorporates a crushing mechanism (material crushing mechanism) to crush the material before pulping and dispersion. This ensures that the solid, lumpy, water-containing material is thoroughly crushed and mixed. The material can be directly fed into the feeding hopper 2, and after crushing, screening, and pre-pulping, it automatically enters the pulping and dispersion tank body 1. No manual pre-crushing is required, significantly improving the efficiency of feeding and pulping. This ensures the uniformity of the material, thereby improving the subsequent pulping and dispersion effects and enhancing the accuracy and reliability of experimental results.

[0030] Some embodiments of the present invention also disclose a pulping and dispersing tank. Based on the above embodiments, to achieve the crushing of solid block materials, the crushing mechanism includes two crushing rollers 4 rotating relative to each other. Each crushing roller 4 includes a roller shaft and crushing teeth. The roller shafts of the two crushing rollers 4 are installed parallel to each other on the tank wall of the tank body 1. The crushing teeth are multiple and evenly arranged on the roller shafts. In use, the two crushing rollers 4 located below the feeding hopper 2 rotate relative to each other. Through the interaction of the crushing teeth on them, the solid block materials are crushed. The crushing rollers 4 can be driven by a motor, which can be set on the outer wall of the tank body 1. Two motors can be used to drive the two crushing rollers 4 to rotate respectively. Roller shaft holes are opened on the tank body 1, and the roller shafts pass through the roller shaft holes and are sealed at the contact points, for example, by using sealing gaskets. The motors are installed outside the crushing chamber and can drive the crushing rollers to rotate through belt drive or gear drive. The parallel arrangement of the two crushing rollers 4 can ensure that the solid block material containing water is evenly subjected to the action of the crushing teeth on the two crushing rollers after entering the crushing chamber, making the crushing effect more stable and uniform. If the materials are not arranged in parallel, they may experience uneven stress during the crushing process, resulting in some materials not being crushed sufficiently and affecting the overall crushing quality.

[0031] The spacing between the two crushing rollers is required, and its size needs to be determined based on the particle size of the material to be crushed in the experiment. Generally, if a finer crushed material is required, the spacing between the two crushing rollers should be set smaller, but not too small to avoid the material being unable to pass through smoothly, and to prevent excessive compression or even collision between the crushing rollers, which could damage the equipment. If a relatively coarser crushed material is required, the spacing can be appropriately increased. In practical applications, the spacing between the two crushing rollers can be adjusted using an adjustment device to meet the needs of different experiments.

[0032] The screening mechanism 5 in this embodiment may include a screening plate and a vibrating device. The screening plate is located at the lower end (bottom) of the crushing chamber 3, and the vibrating device causes the screening plate to vibrate when it is working. The screening plate has multiple screen holes, the size of which is set according to experimental requirements. The crushed material falls through the screen holes into the pre-slurry chamber 6 below. Larger particles that do not pass through the screen holes remain on the screening plate and can be vibrated by the vibrating device to further crush the larger particles by the crushing rollers. Furthermore, the screening plate can be set at a 5-15° angle to the horizontal plane, allowing solid lumps that cannot be crushed into smaller particles to eventually fall to the lowest point of the screening plate.

[0033] Furthermore, a material inlet can be provided on the tank wall at the lowest point of the screening plate to collect solid lumps that fall to the lowest point of the screening plate. The material inlet can also be connected to a residual material storage tank, so that the residual material on the screening plate enters the residual material storage tank under the action of a vibration device.

[0034] In this embodiment, the pre-pulping mechanism includes a pre-pulping agitator 7, which is arranged laterally below the screening plate and has multiple sets of blades. For example, three sets of blades can be provided. The agitator can be driven by a motor, and the motor configuration can be the same as that of the motor in the crushing roller 4, located on the outer wall of the tank body 1. This mechanism can perform preliminary pulverization and agitation on the material falling into the pre-pulping chamber 6, further refining and uniformly mixing the material. A water inlet 9 can be provided on one side of the pre-pulping chamber 6, through which an appropriate amount of water can be injected into the pre-pulping chamber 6 to adjust the concentration of the material.

[0035] To control the discharge from the pre-slurrying chamber 6, the pre-slurrying mechanism may further include a main material assembly 8 disposed at the bottom of the pre-slurrying chamber 6. When the main material assembly 8 is in a first state, the bottom of the pre-slurrying chamber 6 is closed; when the main material assembly 8 is in a second state, a pre-slurry discharge port 10 leading to the slurrying chamber is formed at the bottom of the pre-slurrying chamber 6. In some embodiments, the main material assembly 8 may include an inverted cone extending from the bottom wall of the pre-slurrying chamber towards the center of the tank, a discharge pipe, a valve 11, and a flow regulating device. The upper end of the discharge pipe is connected to the bottom of the inverted cone, and the valve 11 and the flow regulating device are installed on the discharge pipe from top to bottom. The inclination angle of the inverted cone is generally controlled between 30° and 60°. The discharge pipe connects the pre-slurrying chamber and the slurrying and dispersing tank body, and is the channel through which material enters the slurrying and dispersing tank body from the pre-slurrying chamber. The discharge pipe is made of corrosion-resistant metal material (such as stainless steel), and its diameter is rationally designed according to the flow rate and properties of the material, generally between 20-30 mm, to ensure smooth material passage. Valve 11: Installed on the discharge pipe, it controls the flow and stop of material. An electrically controlled valve 11 can be used to control the valve from the tank. A flow regulating device is also located on the discharge pipe, downstream of valve 11. The flow regulating device can use a conventional structure from existing technology.

[0036] In some embodiments of the present invention, during the feeding stage, the operator continuously feeds solid, lumpy, water-containing material into the feeding hopper. Because the feeding hopper is funnel-shaped with a large opening, it facilitates material feeding, and the material enters the crushing chamber from the bottom of the hopper under its own gravity. During the crushing stage, a motor drives two relatively parallel crushing rollers to rotate. When the material enters the crushing chamber, the crushing teeth on the surface of the crushing rollers crush the solid, lumpy, water-containing material. During this process, as long as material continuously enters the crushing chamber, the crushing rollers will continuously crush it, achieving continuity in the crushing process. During the screening stage, the crushed material falls onto the screening plate, and smaller particles fall through the screen holes into the pre-slurrying chamber below. For larger particles that do not pass through the screen holes, a vibration device vibrates the screening plate, causing this portion of material to be crushed again by the crushing rollers, thus ensuring that the material can be continuously screened and crushed again, maintaining the continuity of the entire process. During the pre-slurrying stage, as the material falls into the pre-slurrying chamber, an appropriate amount of water is injected at the inlet, and the pre-slurrying agitator is continuously rotated by a motor. Its spiral blades perform preliminary pulping and mixing of the material, further refining and homogenizing it. As long as material continuously falls into the pre-pulping chamber, the pre-pulping agitator will operate continuously, ensuring a continuous pre-pulping process. In the material and subsequent processing stage, the valve at outlet 10 is opened, allowing the pre-pulped material to continuously enter the pulping and dispersion tank for further pulping and dispersion. The entire process is seamless, achieving continuous feeding and pulping of solid, lumpy, water-containing materials.

[0037] In summary, the pulping and dispersing tank disclosed in this embodiment of the invention, through the addition of feeding and pulping devices, allows solid lumpy water-containing materials to be directly fed into the feeding hopper. After crushing, screening, and pre-pulping, the materials automatically enter the pulping and dispersing tank body, eliminating the need for manual pre-crushing and significantly improving the efficiency of feeding and pulping. The inclusion of crushing rollers and pre-pulping agitators ensures thorough crushing and mixing of the solid lumpy water-containing materials, guaranteeing material uniformity and improving the subsequent pulping and dispersion effects, thus enhancing the accuracy and reliability of experimental results. The entire feeding and pulping process is highly automated; operators only need to feed the material into the feeding hopper and control the valves and motor to complete the feeding and pre-pulping operations, reducing the labor intensity of operators.
