Traditional sludge dewatering methods suffer from low efficiency and poor equipment stability. For example, some dewatering equipment experiences shortened lifespan and poor dewatering effect due to high frictional resistance of rotating parts during operation. Therefore, there is an urgent need for a sludge dewatering device for environmental engineering. Utility Model Content

[0012] Preferably, the outside of the mixing tank is fixedly connected to multiple support legs, and the bottom of each of the multiple support legs is fixedly connected to the outer shell.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] Firstly, in this utility model, the first motor drives the dewatering barrel to rotate at high speed through a gear set, and the bearing reduces the frictional resistance during rotation, which not only ensures that the dewatering barrel can rotate freely, but also improves the stability and service life of the equipment, ensuring the high efficiency of the dewatering process, and is suitable for the reduction treatment of sludge in environmental protection projects.

[0015] Secondly, in this utility model, the pretreatment mechanism adds a chemical conditioner into the mixing tank and uses a stirring rod to stir the sludge, thereby changing the physical and chemical properties of the particles in the sludge. This allows the sludge to have better dewatering conditions before entering the dewatering stage. The valve on the discharge pipe can control the timing of the discharge of the pretreated sludge.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides the following technical solution:

[0023] Example 1

[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 An environmental engineering sludge dewatering device includes a dewatering mechanism, and a pretreatment mechanism is provided on the top of the dewatering mechanism.

[0025] The dehydration mechanism includes a housing 1, inside which a dehydration tank 2 is installed. The top of the dehydration tank 2 is fixedly connected to a feed pipe 3, and the bottom of the dehydration tank 2 is fixedly connected to a discharge pipe 4. A first gear 5 is fixedly connected to the surface of the feed pipe 3. A bracket is fixedly connected to the top of the housing 1, and a first motor 6 is installed on the bracket. The output shaft of the first motor 6 is fixedly connected to a second gear 7, and a drain pipe 8 is fixedly connected to the left side of the housing 1.

[0026] The top of the outer casing 1 is provided with an upper rotating hole, and the feed pipe 3 is installed in the upper rotating hole through a bearing.

[0027] The bottom of the outer casing 1 is provided with a lower rotating hole, and the discharge pipe 4 is rotatably installed in the lower rotating hole through a bearing.

[0028] A sealing cap is installed at the bottom of the discharge pipe 4, and the first gear 5 meshes with the second gear 7.

[0029] Through the above technical solution, the dehydration mechanism uses the outer shell 1 as the basic frame, and the internal dehydration tank 2 is the key component for achieving dehydration. The feed pipe 3 at the top and the discharge pipe 4 at the bottom of the dehydration tank 2 are respectively installed in the upper and lower rotating holes of the outer shell 1 through bearings. This ensures that the dehydration tank 2 can rotate freely, and the bearings reduce the frictional resistance during rotation, thereby improving the stability and service life of the equipment. The first motor 6 is fixed to the top of the outer shell 1 by a bracket, and the second gear 7 connected to its output shaft meshes with the first gear 5 on the surface of the feed pipe 3 to form a gear transmission structure. When the first motor 6 starts, the power is transmitted through... The gear set transmits power to the feed pipe 3, which in turn drives the entire dewatering tank 2 to rotate at high speed. After the sludge enters the high-speed rotating dewatering tank from the feed pipe 3, the water in the sludge is separated under the action of centrifugal force and thrown to the inner wall of the outer shell 1. Finally, it is discharged through the drain pipe 8 on the left side of the outer shell 1. The dewatered sludge remains in the dewatering tank 2. After dewatering is completed, the sealing cover at the bottom of the discharge pipe 4 can be opened to discharge the dewatered sludge. Stable centrifugal motion is achieved through gear transmission. Combined with the rotating structure connected by bearings, the high efficiency of the dewatering process and the reliability of equipment operation are ensured. It is suitable for the reduction treatment of sludge in environmental protection projects.

[0030] Example 2

[0031] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 Furthermore, based on Embodiment 1, the pretreatment mechanism includes a mixing tank 9, a mounting frame 10 is fixedly connected to the top of the mixing tank 9, a second motor 11 is mounted on the top of the mounting frame 10, a stirring shaft 12 is fixedly connected to the output end of the second motor 11, the bottom of the stirring shaft 12 moves through the mounting frame 10 and extends into the mixing tank 9, and stirring rods 13 are fixedly connected to both ends of the stirring shaft 12.

[0032] A discharge pipe 14 is fixedly connected to the bottom of the mixing tank 9, and a valve is installed on the discharge pipe 14.

[0033] Multiple support legs 15 are fixedly connected to the outside of the mixing tank 9, and the bottom of each support leg 15 is fixedly connected to the outer shell 1.

[0034] Through the above technical solution, the pretreatment mechanism takes the mixing tank 9 as the main body and is fixed to the top of the shell 1 of the dewatering mechanism by multiple support legs 15, ensuring the stability of the overall structure. The mounting bracket 10 on the top of the mixing tank 9 is used to fix the second motor 11. The mixing shaft 12 connected to the output end of the second motor 11 extends into the interior of the mixing tank 9. The mixing rods 13 at both ends of the shaft can rotate with the shaft. The raw sludge to be treated first enters the mixing tank 9. By adding chemical conditioning agents into the mixing tank 9, the physical and chemical properties of the particles in the sludge are changed, the colloidal structure of the sludge is destroyed, and the water in the sludge is more easily absorbed. After being separated, the second motor 11 is started, and the stirring shaft 12 drives the stirring rod 13 to rotate, stirring the sludge and accelerating the mixing of the chemical conditioner. The discharge pipe 14 at the bottom of the stirring tank 9 is connected to the feed pipe 3 of the dewatering mechanism. The valve on the discharge pipe 14 can control the timing of the discharge of the pretreated sludge. When the sludge pretreatment is completed, the valve is opened, and the sludge enters the dewatering tank 2 through the discharge pipe 14 for subsequent centrifugal dewatering. By adding a pretreatment step, the sludge has better dewatering conditions before entering the dewatering stage, thereby improving the processing efficiency and dewatering effect of the entire device.
