Moreover, the stirring rod 33 is S-shaped, and at the same time, the second discharge port 9 is opened on the side wall of the tank body 26, so that the material can be pushed towards the second discharge port 9 by the stirring rod 33, improving the convenience and efficiency of discharging;

[0118] Meanwhile, the opening of the filtering cavity 37 ensures the support of the filter plate 35 by the support plate 36 while ensuring the filtering effect on the material.

[0119] Embodiment 6:

[0121] A second jacket assembly 38, installed on the surface of the tank body 26 and including a second jacket connected to the hot water mechanism 3;

[0122] A corrugated tube body 39, sleeved on the surface of the drive shaft 32 and forming a first heating cavity 40 with the surface of the drive shaft 32;

[0123] Wherein, a second heating cavity 41 is formed below the support plate 36, and both the first heating cavity 40 and the second heating cavity 41 are connected to the hot water mechanism 3;

[0124] Meanwhile, the hot water mechanism 3 supplies hot water to the first heating cavity 40 through a connecting pipe. The connecting pipe is connected to the drive shaft 32 by a rotary joint, and a liquid inlet is opened axially on the rotary joint and a liquid outlet is opened on the side.

The settings of the buffer tank 43 and the filter 44 can prevent the material and impurities from entering the vacuum pump 42, thus affecting the use and service life of the vacuum pump 42;

[0135] At the same time, the evacuation of the tank body 26 by the vacuum mechanism 4 can make the melting point and boiling point of the water in the material decrease as the vacuum degree increases, so that the water in the material obtains sufficient kinetic energy to break away from the surface of the material, thereby realizing rapid drying.

[0136] Embodiment 8:

[0137] This embodiment provides a processing system based on the combination of filtration, washing and drying. In addition to including the technical solutions of the above embodiments, it also has the following technical features. The hot water mechanism 3 includes:

[0140] A pressure control assembly 49, installed on the second medium inlet pipe 46 and located between the third condensation assembly 48 and the heating assembly 10, and used to control the hot water pressure entering the heating assembly 10;

[0141] Among them, the water supply unit is the tap water supply, and its specific structure with the steam generation device is an existing mature technology, which will not be elaborated here. And the steam generation device heats the water in the hot water tank 45 through a heating pipe. Specifically, the steam generator circulates and supplies steam into the heating pipe, and heat transfer is carried out between the heating pipe and the water in the hot water tank 45.

[0142] It can be seen from this embodiment that through the setting of the third condensation assembly 48, the temperature of the hot water supplied by the hot water mechanism 3 to the heating assembly 10 can be adjusted, and the pressure control assembly 49 can supply hot water in stages and at different pressures when the hot water mechanism 3 supplies hot water to the heating assembly 10, ensuring the supply efficiency, improving the heat transfer efficiency and energy utilization rate, and avoiding energy waste.

[0143] Embodiment 9:

[0144] This embodiment provides a processing system based on the combination of filtration, washing and drying. In addition to including the technical solutions of the above embodiments, it also has the following technical features. The pressure control assembly 49 includes:

[0145] A first bypass pipe 50, which is connected in parallel to the second medium inlet pipe 46 and is provided with a first opening and closing valve 51;

[0146] A second bypass pipe 52, which is connected in parallel to the second medium inlet pipe 46 and is arranged in parallel with the first bypass pipe 50, and is provided with a second opening and closing valve 53, a first pressure reducing orifice plate 54 and a first pressure reducing valve 55;

[0147] Among them, the second medium inlet pipe 46 is provided with a third opening and closing valve 56 and a second pressure reducing orifice plate 57 at the positions of the first bypass pipe 50 and the second bypass pipe 52, and the second medium inlet pipe 46 is provided with a pressure sensor 58 on one side close to the pressure control assembly 49 and a fourth opening and closing valve 59 on the other side;

[0148] At the same time, the pressure reducing orifice plate is a structure that reduces the pressure by changing the cross-sectional areas of its input end and output end, and its specific structures with the opening and closing valve and the pressure reducing valve are existing mature technologies, which will not be elaborated here.

[0149] In this embodiment, only one of the first opening and closing valve 51, the second opening and closing valve 53 and the third opening and closing valve 56 can be opened. Therefore, it can prompt the hot water mechanism 3 to supply hot water with different pressures to the heating assembly 10, and then present different stages during the hot water transportation and correspond to different pressures respectively. This can improve the supply efficiency of hot water in the initial stage. After reaching dynamic balance, the supply pressure can be reduced, thereby slowing down the hot water replacement efficiency in the heating assembly 10, and then effectively improving the heat transfer efficiency and reducing energy consumption;

[0150] Specifically, at the initial stage when the hot water mechanism 3 supplies hot water to the heating component 10, the fourth on-off valve 59 and the first on-off valve 51 are opened, and the second on-off valve 53 and the third on-off valve 56 are closed. At this time, the conveying pressure is the greatest, so the efficiency of filling the heating component 10 with hot water can be effectively improved;

[0151] When the hot water mechanism 3 supplies hot water to the heating component 10 and is close to being full or just full, the fourth on-off valve 59 and the third on-off valve 56 are opened, and the first on-off valve 51 and the second on-off valve 53 are closed. At this time, the conveying pressure is reduced by the influence of the second pressure reducing orifice plate 57, and then the pressure of the hot water entering the heating component 10 can be slowed down, avoiding excessive pressure fluctuations in the heating component 10, improving stability, and ensuring safety;

[0152] When the hot water mechanism 3 supplies hot water to the heating component 10 and reaches dynamic balance, the fourth on-off valve 59 and the second on-off valve 53 are opened, and the first on-off valve 51 and the third on-off valve 56 are closed. Here, the conveying pressure is further reduced by the action of the first pressure reducing orifice plate 54 and the first pressure reducing valve 55, which can slow down the circulation efficiency of the hot water in the heating component 10, and then improve the heat transfer efficiency of the hot water, improve the utilization rate, and avoid energy consumption waste;

[0153] At the end stage when the hot water mechanism 3 supplies hot water to the heating component 10, that is, when the material drying is approaching the end, the fourth on-off valve 59, the third on-off valve 56, the second on-off valve 53 and the first on-off valve 51 are closed, that is, the supply of hot water and the circulation of hot water are stopped, and the operation of the hot water mechanism 3 is stopped in advance, which can further avoid the waste of energy consumption and improve the utilization rate;

[0154] At the same time, after the drying is completed, the fourth on-off valve 59, the third on-off valve 56, the second on-off valve 53 and the first on-off valve 51 are in the closed state, and cold water can be introduced into the heating component 10 to replace the hot water and cool the material.

[0155] Example 10:

[0156] This embodiment provides a processing technology for a processing system based on the combination of filtration, washing and drying, including the following steps:

[0157] S1: Convey the material to the reaction kettle 13 for full reaction;

[0158] S2: Convey the material in the reaction kettle 13 to the tank body 26 of the drying mechanism 2;

[0159] S3: Filter the material through the filtering component 11 and collect the mother liquor through the mother liquor tank 27;

[0160] S4: Wash the material through the washing nozzle 12 and drive the stirring component to rotate through the driving component 34;

[0161] S5: After the washing is completed, drain the washing wastewater.

[0162] S6: The hot water mechanism 3 conveys the hot water medium to the heating component 10, heats the interior of the tank body 26, and dries the material at the same time.

[0163] S7: After the drying is completed, perform cooling. At the same time, the vacuum mechanism 4 evacuates the drying mechanism 2 and introduces nitrogen to balance the pressure. Then, discharge the dried and cooled material through the second discharge port 9.

[0164] S8: Wash the tank body 26 through the washing nozzle 12 and drain the washing wastewater.

[0165] It can be seen from this embodiment that through the above steps, filtration, washing, and drying operations are carried out in the drying mechanism 2. By using a three-in-one device, a large number of devices and space are not required, the operation is simple, the energy consumption is low, and the pollution risk during the material transfer process is avoided.
