Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically to an environmentally friendly sludge treatment device. Background Technology

[0002] Sludge is composed of solid matter from the original wastewater and solid matter generated during wastewater treatment. Sludge treatment is a process of reducing, stabilizing, and rendering harmless sludge through concentration, conditioning, dewatering, stabilization, drying, or incineration. Existing sludge treatment equipment typically involves squeezing and filtering the sludge before conveying it to a drying area. However, the water vapor evaporated during sludge drying may contain harmful substances, which can easily cause environmental pollution when released into the air. Furthermore, the water vapor is directly released outdoors without being cooled, which can negatively impact the atmospheric environment and results in poor environmental performance. Utility Model Content

[0003] In view of this, the present invention provides an environmentally friendly sludge treatment device that can purify the water vapor during sludge drying to prevent harmful substances from being directly released into the air, and can also cool the water vapor before releasing it to prevent pollution of the atmospheric environment.

[0004] To solve the above-mentioned technical problems, this utility model provides an environmentally friendly sludge treatment device, including an operating platform. A dryer body is installed on the upper inner wall of the operating platform, and a conveying mechanism is installed below the inside of the operating platform. A treatment box is installed on the upper part of the operating platform, and an exhaust fan is installed below the treatment box. The exhaust end of the exhaust fan penetrates through the upper wall of the operating platform, and the exhaust end of the exhaust fan penetrates through the lower wall of the treatment box. A purification tank is opened at the lower inside of the treatment box, and a purification mechanism is installed in the purification tank to purify and filter water vapor. A cooling mechanism is installed in the center of the inside of the treatment box to cool the water vapor. During the cooling process, workers place the pumped sludge onto a conveyor mechanism, where it is dried by the dryer itself. The water vapor evaporated from the dried sludge is then drawn into the lower part of the treatment tank by an exhaust fan, allowing the water vapor to enter the purification tank. The purification mechanism absorbs and removes harmful substances from the water vapor. The purified water vapor then enters the upper part of the treatment tank and is cooled by a cooling mechanism. This process purifies the water vapor during sludge drying, preventing harmful substances from being directly released into the air and also cooling the water vapor before it is released, thus preventing atmospheric pollution.

[0005] The purification system includes an absorption screen installed inside the purification tank. The absorption screen can purify and filter harmful substances in water vapor, preventing harmful substances from being directly emitted into the air.

[0006] The purification tank has slide rails on its two inner side walls, with a mounting frame sliding inside the slide rails. The absorbent net is fixed inside the mounting frame. A through groove is opened below the surface of the treatment box. A matching sealing plate is installed on the side wall of the mounting frame, corresponding to the position of the through groove. The sealing plate is inserted into the through groove on the surface of the treatment box. When the absorbent net needs to be replaced and recycled after a long period of use, the sealing plate is pulled, causing the sealing plate to disengage from the through groove on the surface of the treatment box. At the same time, the sealing plate drives the mounting frame to slide in the slide rails, so that the mounting frame and the absorbent net inside are disengaged from the purification tank, thus facilitating the replacement and recycling of the absorbent net.

[0007] The cooling mechanism includes a motor mounted on one side wall of the processing chamber. The fixed end of the motor is fixed to the side wall of the processing chamber, and the output end of the motor penetrates through the side wall of the processing chamber. A heat dissipation pipe made of metal is installed at the output end of the motor. Several cooling fans are evenly arranged at the top of the processing chamber. The air outlet of the cooling fans penetrates through the upper wall of the processing chamber. When the operator starts the motor, the output end of the motor drives the heat dissipation pipe to rotate. At the same time, the cooling fans blow cold air onto the surface of the heat dissipation pipe, so that when the water vapor rises, it comes into contact with the surface of the heat dissipation pipe to cool the water vapor. The cooling fans also dissipate heat from the heat dissipation pipe. Because the heat dissipation pipe is made of metal, its thermal conductivity is better, which allows for faster cooling. This allows the heat dissipation pipe to continuously cool the water vapor and prevent atmospheric pollution.

[0008] A support rod is provided at one end of the heat dissipation pipe, and a fixed seat is provided on the other side wall of the processing box. A bearing is fixed to the inner wall of the fixed seat, and the outer wall of the support rod is fixed to the inner ring of the bearing. The outer ring of the bearing is fixed to the inner wall of the fixed seat. The cooling mechanism also includes an exhaust assembly, which is used to exhaust the air inside the processing box. When the heat dissipation pipe rotates, it drives the support rod to rotate in the bearing, so that the support rod supports the heat dissipation pipe and improves the stability of the heat dissipation pipe during rotation. When the heat dissipation pipe dissipates water vapor, the exhaust assembly can exhaust the air after heat dissipation inside the processing box to the outside.

[0009] The exhaust assembly includes an exhaust pipe mounted on the upper side wall of the treatment chamber, an exhaust groove on the surface of the exhaust pipe, a rotating rod rotatably mounted at the center of the exhaust pipe, a fan blade at the end of the rotating rod, one end of the rotating rod penetrating the inner wall of the exhaust pipe and having a driven sprocket at the other end, and a drive sprocket at the end of a support rod. A chain is connected to the surfaces of the drive sprocket and the driven sprocket. When the support rod rotates with the heat dissipation pipe, the support rod drives the drive sprocket to rotate, the drive sprocket drives the driven sprocket to rotate via the chain, the driven sprocket drives the rotating rod to rotate, and the rotating rod drives the fan blade to rotate, so that the fan blade draws the cooled water vapor inside the treatment chamber into the exhaust pipe, and then discharges it outdoors through the exhaust groove above the exhaust pipe.

[0010] The cooling mechanism also includes a scraping component installed on the rear wall inside the processing chamber. The scraping component is used to scrape off condensed water droplets on the surface of the tube. When the heat dissipation tube cools the water vapor, the water vapor condenses into small water droplets when it comes into contact with the heat dissipation tube. The scraping component can scrape off the small water droplets on the surface of the heat dissipation tube, so that the heat dissipation tube can continue to dissipate heat and prevent water droplets from dripping onto the surface of the absorption mesh.

[0011] The scraping assembly includes a fixed plate installed on the rear wall inside the processing tank. The fixed plate has a fixed post on its surface, and a scraper is installed at the end of the fixed post. The end face of the scraper contacts the surface of the heat dissipation pipe. The scraping assembly also includes a recovery component installed below the fixed plate. The recovery component is used to discharge and recover the scraped water. When the heat dissipation pipe rotates, the end face of the scraper contacts the surface of the heat dissipation pipe, so that the scraper intercepts the water droplets on the surface of the heat dissipation pipe below the scraper, so that the water droplets fall into the recovery component for recovery. The scraper is made of rubber, which allows the scraper to make a tighter contact with the heat dissipation pipe.

[0012] The recycling component includes a guide pipe located below the surface of the fixed plate. The upper part of the guide pipe is sloped, and a drain pipe is located at the end of the guide pipe with the slope facing downwards. The drain pipe penetrates the inner wall of the treatment tank. Water droplets scraped off by the scraper fall into the guide pipe and flow through the slope of the guide pipe to the drain pipe, from where they are discharged from the treatment tank. Workers can place a recycling tank at the lower end of the discharge pipe to recycle the water, thus saving water resources.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. When using this utility model, the worker places the sludge after pumping water onto the conveying mechanism, and the sludge is dried by the dryer body. The water vapor evaporated from the dried sludge is then drawn into the lower part of the treatment box by the exhaust fan, so that the water vapor enters the purification tank. The purification mechanism absorbs and purifies the harmful substances in the water vapor. The purified water vapor enters the upper part of the treatment box and is then cooled by the cooling mechanism. In this way, the water vapor evaporated during the sludge drying process is purified, preventing harmful substances from being directly released into the air. It can also cool the water vapor before it is released, preventing pollution of the atmospheric environment.

[0015] 2. When using this utility model, if the absorption net needs to be replaced and recycled after a long period of use, pull the sealing plate to disengage it from the through groove on the surface of the treatment box. At the same time, the sealing plate drives the mounting frame to slide in the slide rail, so that the mounting frame and the internal absorption net disengage from the purification tank, thereby facilitating the replacement and recycling of the absorption net.

[0016] 3. When using this utility model, the operator starts the motor, and the output end of the motor drives the heat dissipation pipe to rotate. At the same time, the cooling fan blows cold air onto the surface of the heat dissipation pipe, so that when the water vapor rises, it comes into contact with the surface of the heat dissipation pipe to cool the water vapor. The cooling fan also dissipates heat from the heat dissipation pipe. Since the heat dissipation pipe is made of metal, its heat conduction effect is better, so it can cool down faster. This allows the heat dissipation pipe to continuously cool the water vapor and prevent pollution of the atmospheric environment.

[0017] 4. When this utility model is in use, the support rod rotates along with the heat dissipation pipe, which drives the drive sprocket to rotate. The drive sprocket drives the driven sprocket to rotate through the chain. The driven sprocket drives the rotating rod to rotate, and the rotating rod drives the fan blade to rotate. This causes the fan blade to draw the cooled water vapor inside the treatment box into the exhaust pipe, and then discharge it outdoors through the exhaust slot above the exhaust pipe.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] According to one embodiment of the present invention, such as Figure 1-4 As shown: This embodiment provides an environmentally friendly sludge treatment device, including an operating platform 100. A dryer body 101 is installed on the upper inner wall of the operating platform 100. A conveying mechanism is installed at the lower interior of the operating platform 100. A treatment box 200 is installed on the upper part of the operating platform 100. An exhaust fan 202 is installed at the lower part of the treatment box 200. The exhaust end of the exhaust fan 202 penetrates through the upper wall of the operating platform 100, and the exhaust end of the exhaust fan 202 penetrates through the lower wall of the treatment box 200. A purification tank 800 is opened at the lower interior of the treatment box 200. A purification mechanism is installed in the purification tank 800 to purify and filter water vapor. A cooling machine is installed at the center of the interior of the treatment box 200. The structure includes a cooling mechanism to cool the water vapor. After the sludge is pumped out, it is placed on the conveying mechanism and dried by the dryer body 101. The water vapor evaporated from the dried sludge is then drawn into the lower part of the treatment box 200 by the exhaust fan 202, so that the water vapor enters the purification tank 800. The purification mechanism absorbs and purifies the harmful substances in the water vapor. The purified water vapor enters the upper part of the treatment box 200 and is then cooled by the cooling mechanism. This process purifies the water vapor during sludge drying, preventing harmful substances from being directly released into the air. It also cools and releases the water vapor, preventing pollution of the atmospheric environment.

[0025] The purification mechanism includes an absorption net 803 installed inside the purification tank 800. The absorption net 803 can purify and filter harmful substances in water vapor, preventing harmful substances from being directly emitted into the air.

[0026] The purification tank 800 has slide rails 801 on its two inner side walls. An installation frame 802 is slidably installed inside the slide rails 801. The absorption net 803 is fixed inside the installation frame 802. A through groove is opened below the surface of the treatment box 200. A matching sealing plate 804 is installed on the side wall of the installation frame 802 at the position of the through groove. The sealing plate 804 is inserted into the through groove on the surface of the treatment box 200. When the absorption net 803 needs to be replaced and recycled after a long period of use, the sealing plate 804 is pulled to disengage from the through groove on the surface of the treatment box 200. At the same time, the sealing plate 804 drives the installation frame 802 to slide in the slide rails 801, so that the installation frame 802 and the absorption net 803 inside it are disengaged from the purification tank 800, thereby facilitating the replacement and recycling of the absorption net 803.

[0027] The cooling mechanism includes a motor 400 mounted on one side wall of the processing chamber 200. The fixed end of the motor 400 is fixed to the side wall of the processing chamber 200, and the output end of the motor 400 penetrates through the side wall of the processing chamber 200. A heat dissipation pipe 300, made of metal, is installed at the output end of the motor 400. Several cooling fans 700 are evenly arranged on the upper part of the processing chamber 200. The air outlet of the cooling fans 700 penetrates through the upper wall of the processing chamber 200. When the operator starts the motor 400, the output end of the motor 400 drives the heat dissipation pipe 300 to rotate. At the same time, the cooling fans 700 blow cold air onto the surface of the heat dissipation pipe 300, so that when the water vapor rises, it comes into contact with the surface of the heat dissipation pipe 300 to cool the water vapor. The cooling fans 700 also dissipate heat from the heat dissipation pipe 300. Since the heat dissipation pipe 300 is made of metal, its thermal conductivity is better, which allows for faster cooling. This allows the heat dissipation pipe 300 to continuously cool the water vapor and prevent pollution of the atmospheric environment.

[0028] A support rod 301 is provided at one end of the heat dissipation pipe 300, and a fixed seat 500 is provided on the other side wall of the processing box 200. A bearing 501 is fixed to the inner wall of the fixed seat 500, and the outer wall of the support rod 301 is fixed to the inner ring of the bearing 501. The outer ring of the bearing 501 is fixed to the inner wall of the fixed seat 500. The cooling mechanism also includes an exhaust assembly, which is used to exhaust the air inside the processing box 200. When the heat dissipation pipe 300 rotates, it drives the support rod 301 to rotate in the bearing 501, so that the support rod 301 supports the heat dissipation pipe 300 and improves the stability of the heat dissipation pipe 300 during rotation. When the heat dissipation pipe 300 dissipates water vapor, the exhaust assembly can exhaust the air after heat dissipation inside the processing box 200 to the outside.

[0029] The exhaust assembly includes an exhaust pipe 600 disposed above the side wall of the processing box 200. An exhaust groove is formed on the surface of the exhaust pipe 600. A rotating rod 601 is rotatably mounted at the center of the exhaust pipe 600. A fan blade 604 is provided at the end of the rotating rod 601.

A drive sprocket 502 is provided at the end of the support rod 301. The drive sprocket 502 and the driven sprocket 602... The surface is connected by a chain 603. When the support rod 301 rotates with the heat sink 300, the support rod 301 drives the drive sprocket 502 to rotate. The drive sprocket 502 drives the driven sprocket 602 to rotate through the chain 603. The driven sprocket 602 drives the rotating rod 601 to rotate. The rotating rod 601 drives the fan blade 604 to rotate, so that the fan blade 604 draws the water vapor that has been cooled inside the processing box 200 into the exhaust pipe 600, and then discharges it to the outside through the exhaust slot above the exhaust pipe 600.

[0030] The cooling mechanism also includes a scraping component installed on the rear wall inside the processing box 200. The scraping component is used to scrape off the condensed water droplets on the surface of the tube. When the heat dissipation tube 300 cools the water vapor, the water vapor condenses into small water droplets when it comes into contact with the heat dissipation tube 300. The scraping component can scrape off the small water droplets on the surface of the heat dissipation tube 300, so that the heat dissipation tube 300 can continue to dissipate heat and prevent water droplets from dripping onto the surface of the absorption net 803.

[0031] The scraping assembly includes a fixing plate 900 disposed on the rear wall inside the processing box 200. The fixing plate 900 has a fixing post 901 disposed on its surface. The fixing post 901 has a scraper 902 disposed at its end. The end face of the scraper 902 contacts the surface of the heat dissipation pipe 300. The scraping assembly also includes a recycling component disposed below the fixing plate 900. The recycling component is used to discharge and recycle the scraped water. When the heat dissipation pipe 300 rotates, the end face of the scraper 902 contacts the surface of the heat dissipation pipe 300, so that the scraper 902 intercepts the water droplets on the surface of the heat dissipation pipe 300 below the scraper 902, so that the water droplets fall into the recycling component for recycling.

The staff can place a recycling box at the lower end of the discharge pipe to recycle the water and save water resources.

[0033] How to use this utility model:

[0034] First, it needs to be clarified that this utility model relates to sludge treatment, mainly used to purify and cool the water vapor generated by sludge evaporation. The dryer body 101 and the conveying mechanism are common devices in the prior art. Since they are not the main technical features of this utility model, the model will not be limited here, nor will their structure be described in detail. Only the usage method and installation position of the cooling mechanism will be described in detail. When sludge needs to be treated, the sludge after pumping water is placed on the conveying mechanism, and the dryer body 101 dries the sludge. After drying... The water vapor evaporated from the sludge is then drawn into the lower part of the treatment tank 200 by the exhaust fan 202, allowing the water vapor to enter the purification tank 800. The absorption net 803 can purify and absorb harmful substances in the water vapor. The purified water vapor rises and contacts the surface of the heat dissipation pipe 300, causing the heat dissipation pipe 300 to cool the water vapor. The cooling fan 700 dissipates heat from the heat dissipation pipe 300. Because the heat dissipation pipe 300 is made of metal, its thermal conductivity is better, thus allowing for faster cooling. The water vapor contacts the heat dissipation pipe 300. Subsequently, water vapor condenses into small water droplets upon cooling. As the heat dissipation pipe 300 rotates, the end face of the scraper 902 contacts the surface of the heat dissipation pipe 300, causing the scraper 902 to intercept the water droplets below it. The water droplets then fall into the guide pipe 903 and flow through the inclined surface of the guide pipe 903 to the drain pipe 904, from where they are discharged into the treatment tank 200. Workers can place a recycling tank at the lower end of the drain pipe to collect the water. Furthermore, as the support rod 301 rotates with the heat dissipation pipe 300, the support rod 301... The drive sprocket 502 rotates, which in turn drives the driven sprocket 602 to rotate via the chain 603. The driven sprocket 602 drives the rotating rod 601 to rotate, which in turn drives the fan blade 604 to rotate. This causes the fan blade 604 to draw the cooled water vapor inside the treatment box 200 into the exhaust pipe 600, and then discharge it outdoors through the exhaust trough above the exhaust pipe 600. This process can purify the water vapor during sludge drying, preventing harmful substances from being directly released into the air, and can also cool the water vapor before it is discharged, preventing atmospheric pollution.

[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
