Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to an environmentally friendly dehydration device. Background Technology

[0002] Dewatering equipment is a type of machinery or device used to remove excess water from materials, and is widely used in industries such as food processing, chemicals, mining, and pharmaceuticals. It removes water from liquid materials through mechanical pressure, centrifugation, thermal drying, or other methods to achieve weight reduction, preservation, or further processing. Sludge dewatering equipment, on the other hand, is a mechanical device specifically designed to remove water from sludge, aiming to reduce its volume and facilitate storage, transportation, and final disposal. It is extremely important in wastewater treatment plants and industrial wastewater treatment, helping to stabilize sludge and achieve resource recovery.

[0003] Existing sludge dewatering equipment partially uses pressure filtration to remove water from the sludge. The dewatered sludge blocks are collected for subsequent processing, but these sludge blocks inevitably retain a small amount of water, making them muddy and causing inconvenience for workers in storage and transportation.

[0004] Therefore, those skilled in the art have provided an environmentally friendly dehydration device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an environmentally friendly dehydration device. This device effectively reduces the residual moisture in the mud cake through continuous hot air drying, making it dry and firm, facilitating storage and transportation, reducing the inconvenience caused by mud and moisture, and improving work efficiency and processing safety. Simultaneously, the uniform blowing of hot air ensures even drying of the mud cake, enhancing the overall dehydration effect and contributing to subsequent resource recycling and environmental protection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly dehydration device, including a dehydrator body, wherein a receiving mechanism is fixedly provided at the lower end of the discharge end of the dehydrator body;

[0007] The receiving mechanism includes a receiving box, a cylinder is fixedly installed at the front center of the receiving box, a heating column is fixedly installed at the upper end of the cylinder, multiple holes are opened on the heating column, a slide is arranged around the outer surface of the heating column, a hot air fan is fixedly installed inside the cylinder, and a guide ring is fixedly installed in the middle of the inner wall of the heating column.

[0008] Furthermore, the plurality of holes are evenly distributed around the body of the heating column.

[0009] Furthermore, the upper opening of the slide is fixedly connected to the lower end of the discharge end of the dewatering machine body.

[0010] Furthermore, the inner top surface of the heating column has a semi-circular design.

[0011] Furthermore, an air inlet is provided at the lower end of the cylinder.

[0012] This utility model has the following beneficial effects:

[0013] This utility model proposes an environmentally friendly dewatering device. The dewatering device catches the mud cake at the discharge end of the dewatering machine body through a slide. The mud cake rolls down the slide into the receiving box. As the mud cake rolls down the slide, hot air blown by a hot air blower is blown out through the holes on the heating column, thereby blowing the mud cake rolling down the slide and drying the moisture inside the mud cake, making it easy to store and transport.

[0022] 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.

[0023] Reference Figure 1, Figure 2 One embodiment of this utility model is an environmentally friendly dehydration device, which includes a dehydrator body 1 and a receiving mechanism 3 fixedly installed at the lower end of the discharge end of the dehydrator body 1.

[0024] Specifically, the dewatering machine body 1 consists of the following components: motor, moving plates, fixed plates, fixed plate, screw shaft, screw blades, feed box, water receiving tank, frame, and discharge baffle. The working principle of the dewatering machine body 1 is as follows: When sludge enters the equipment through the feed box, it first enters the thickening section. In this stage, the motor drives the screw shaft to rotate, pushing the sludge forward along the screw direction through the screw blades. The multiple moving and fixed plates on the periphery move relative to each other. Under the action of gravity, the wastewater is filtered out through the gaps between the relatively moving plates. Then, the thickened sludge continues to enter the dewatering section as the screw shaft rotates, and the pressure on the sludge gradually increases. Along the direction of the sludge cake discharge end, the screw pitch gradually decreases, and the gap between the rings also gradually decreases, causing the cavity volume to continuously shrink. Under the action of the discharge baffle at the discharge end, the internal pressure gradually increases. Driven by the continuous operation of the screw shaft, the water in the sludge cake is squeezed out, and the solid content of the sludge cake continuously increases, ultimately achieving continuous dewatering of the sludge. The dewatered sludge cake is discharged from the discharge end.

[0025] Reference Figures 3-6 The receiving mechanism 3 includes a receiving box 301. A cylinder 302 is fixedly installed at the middle of the front end of the receiving box 301. A heating column 303 is fixedly installed at the upper end of the cylinder 302. Multiple holes 304 are opened on the body of the heating column 303. A slide rail 305 is arranged around the outer surface of the heating column 303. A hot air blower 306 is fixedly installed inside the cylinder 302. A guide ring 307 is fixedly installed in the middle of the inner wall of the heating column 303. Multiple holes 304 are evenly distributed around the body of the heating column 303. The upper opening of the slide rail 305 is fixedly connected to the lower end of the discharge end of the dewatering machine body 1. The inner top surface of the heating column 303 is semi-circular. An air inlet is opened at the lower end of the cylinder 302.

[0026] Specifically, when the hot air blower 306 starts working, it draws in outside air through the air inlet at the lower end of the cylinder 302, and then blows the hot air out from the upper end of the cylinder 302. This hot air enters the interior of the heating column 303, and then the hot air inside the heating column 303 is blown out through multiple holes 304, thereby drying and blowing the mud cake on the slide 305. Then, the guide ring 307 set in the middle of the inner wall of the heating column 303 can increase the wind speed when the hot air inside the heating column 303 passes through the ring, so that the hot air can be blown to the top surface inside the heating column 303. The top surface inside the heating column 303 is designed as a semi-circular shape, so that when the hot air blows to the top, it can easily flow back into the heating column 303 through the semi-circular arc surface. In addition, the surface of the slide 305 is coated with a hydrophobic coating to prevent the mud cake from sticking.

[0027] Working principle: After the dewatering machine body 1 dewaters the sludge, the treated sludge cake will fall from the discharge end onto the slide 305 and roll down along the slide 305. When the operator starts the power, the hot air blower 306 starts working. The hot air blower 306 will blow hot air into the interior of the heating column 303. Then, this hot air will be blown out from multiple holes 304. This hot air blows the sludge cake that is rolling down the slide 305, thereby drying the residual water on the sludge cake. The dried sludge cake will then roll down the slide 305 into the receiving box 301. The dried sludge cake is easy for the operator to store and transport.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
