[0029] Please see Figures 1-8 In this embodiment of the present invention, an environmental engineering solid waste treatment device includes a support frame 1, a pretreatment mechanism 2 disposed above the support frame 1, and a separation mechanism 3 disposed below the support frame 1. The pretreatment mechanism 2 includes a separation chamber 201, a guide chamber 202, a preheating chamber 205, a first rotating rod 207, and a first cutter 208. The separation chamber 201 is fixedly installed at the upper end of the support frame 1, the guide chamber 202 is fixedly installed at the upper end of the separation chamber 201, the preheating chamber 205 is fixedly installed at the left end of the guide chamber 202, the first rotating rod 207 is installed at the right end inside the separation chamber 201, and the first cutter 208 is installed on the first rotating rod 207. The pretreatment mechanism 2 also includes a support plate 203 and a first conveyor belt 204. The left end of the guide chamber 202 is fixedly installed with a first cutting blade 208. A support plate 203 is provided, and a first conveyor belt 204 is installed on the upper end of the support plate 203. A preheating chamber 205 is located outside the first conveyor belt 204.

A second transmission turntable 214 is installed at the front end of the second rotating rod 209. A second transmission belt 215 is installed on the second transmission turntable 214.

[0030] See Figure 6 , Figure 7 and Figure 8Initially, the support frame 1, pretreatment mechanism 2, and separation mechanism 3 together constitute the sludge solid waste treatment equipment, mainly for pretreatment of sludge. It requires the use of a sludge pressing structure. First, the pretreatment mechanism 2 heats and cuts the sludge. Second, the separation mechanism 3 conveys the sludge and collects the water discharged from the sludge during the conveying process. Before operation, the first conveyor belt 204, heating wire mesh 206, first drive motor 213, second drive motor 216, and second conveyor belt 304 need to be powered on and connected to the control terminal. During operation, the heating wire mesh 206 needs to be activated beforehand to heat the sludge, thereby increasing the temperature inside the preheating chamber 205 to moderately heat the sludge. As the temperature rises, the sludge is placed on the first conveyor belt 204 and preheated in the preheating chamber 205. It is then transported by the first conveyor belt 204 to the separation chamber 201. At the same time, the first drive motor 213 drives the first transmission belt 212 and the first transmission turntable 211 to rotate, which in turn causes the first rotating rod 207 and the first cutter 208 to rotate at high speed. Similarly, the second drive motor 216 drives the second transmission belt 215 and the second transmission turntable 214 to rotate, which in turn causes the second rotating rod 209 and the second cutter 210 to rotate at high speed. When the sludge arrives in the separation chamber 201, the first cutter 208 and the second cutter 210 will quickly cut the sludge to facilitate subsequent sludge treatment operations.

[0031] The pretreatment unit 2 mainly includes a cutting structure and a heating structure. Heating not only reduces the viscosity of the sludge but also promotes the evaporation of water in the sludge, increasing the fluidity of the sludge. In this way, the sludge is more easily pressed by the screw when it enters the pressing process, improving the pressing efficiency. When the sludge passes through the cutting structure, it is shredded by the high-speed rotation force and sharpness of the blades. The shredding process not only reduces the size of the sludge particles but also destroys the fibrous structure in the sludge, thereby reducing the viscosity of the sludge. This physical crushing process improves the fluidity of the sludge, making it easier for subsequent pressing processing.

[0032] The separation mechanism 3 includes a water collection tank 301 and a second conveyor belt 304. The second conveyor belt 304 is arranged below the separation tank 201, and the water collection tank 301 is arranged below the second conveyor belt 304. The separation mechanism 3 also includes a drain pipe 302. The drain pipe 302 is fixedly installed at the lower end of the water collection tank 301. A support frame 303 is fixedly installed on the inner wall of the water collection tank 301. A protective plate 305 is fixedly installed at the upper end of the support frame 303. The protective plate 305 is located on the outside of the second conveyor belt 304.

[0033] See Figure 6 , Figure 7 and Figure 8Initially, the separation mechanism 3 is used to receive the sludge in the pretreatment mechanism 2. The second conveyor belt 304 has a hollow structure with a large number of hollow grooves to facilitate the rapid discharge of water from the sludge. After the sludge is cut in the separation chamber 201, it will fall onto the second conveyor belt 304. The second conveyor belt 304 needs to be connected to the sludge pressing structure. After the second conveyor belt 304 transports the sludge, the water in the sludge will flow into the water collection chamber 301, and the water can be discharged through the drain pipe 302.

[0034] The working principle of this utility model is as follows: The equipment mainly includes a support frame 1, a pretreatment mechanism 2, and a separation mechanism 3. During operation, the entire system is first securely installed on the ground via the support frame 1. A heating wire mesh 206 is installed inside the preheating chamber 205 of the pretreatment mechanism 2. The first drive motor 213 and the second drive motor 216 drive the first rotating rod 207 and the second rotating rod 209 to rotate at high speed, respectively, causing the first cutter 208 and the second cutter 210 to cut the sludge entering the separation chamber 201. Simultaneously, the heating wire mesh 206 in the preheating chamber 205 moderately heats the sludge, increasing its temperature and reducing its viscosity, facilitating subsequent cutting and pressing operations. The cut sludge is then transported to the separation chamber 201 via the first conveyor belt 204. The sludge falls onto the second conveyor belt 304 of the separation mechanism 3. The second conveyor belt 304 has a hollow structure, allowing water in the sludge to be quickly discharged through the hollow grooves and flow into the water collection tank 301 below. The water collection tank 301 discharges the water through the drain pipe 302, achieving effective separation of sludge and water. The protective plate 305 is located on the outside of the second conveyor belt 304, providing protection and preventing sludge from splashing. The entire equipment is uniformly controlled and monitored through the environmental engineering solid waste treatment system terminal, which ensures stable operation and treatment effect. This equipment has high practicality and innovation, and can effectively solve the problems of low treatment efficiency, high energy consumption, and high operating costs of traditional sludge treatment equipment, providing an efficient and economical solution for environmental engineering solid waste treatment.
