[0002] In the construction industry, cement is a crucial material, known as the "grain" of construction. It is a powdery binder that can be mixed with water and other materials to form concrete, which is the basis of building structures. Cement is divided into various types, and different types of cement have different properties, such as strength, impermeability, etc. Cement is usually made by mixing limestone, clay, iron ore powder and some auxiliary materials in a certain proportion and undergoing high-temperature calcination. Its main chemical components are calcium silicate and calcium aluminate, etc. Cement is plastic and can be shaped into the required form. The hardened cement structure has good compressive strength and durability.

Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 6 The present invention provides a technical solution: an exhaust gas treatment device with a quick-release structure, including an intake pipe 1, the intake pipe 1 is inserted into one side of the top of the air delivery box 2, the bottom end of the air delivery box 2 is provided with a cooling box 3, the left and right inner side walls of the cooling box 3 are horizontally penetrated by a cooling mechanism 4, the bottom end of the cooling box 3 is clamped to the top end of the filter box 5, the inner wall of the filter box 5 is fitted with a filter mechanism 6, the bottom of the filter box 5 is provided with an exhaust box 7, one side outer wall of the exhaust box 7 is horizontally penetrated by an exhaust mechanism 8, and the other side outer wall of the exhaust box 7 is provided with an exhaust pipe 9.

[0024] In this embodiment, as Figure 1 and Figure 5 shown, a fan 201 is clamped to the middle of the top wall of the air delivery box 2; it should be noted that when the exhaust gas from cement processing production enters the inside of the air delivery box 2 through the intake pipe 1, the operator can start the fan 201 to make its fan blades start to rotate, thereby driving the gas around it to blow downward. During this period, due to the power generated by the operation of the fan 201, the exhaust gas flow passing by it can flow downward into other boxes more quickly, so that the contact probability between the exhaust gas and the cooling mechanism 4 and the filter mechanism 6 can be effectively increased, thereby improving its treatment efficiency. Moreover, by adjusting the rotation speed of the fan 201, the amount of exhaust gas entering the intake pipe 1 can also be controlled, so as to realize the adaptive adjustment of the air flow speed and the treatment system.

[0025] In this embodiment, as Figure 2 and Figure 5As shown in the figure, the outer wall of the bottom end of the cooling box 3 is provided with an insertion strip 301, and the outer wall of the top end of the filter box 5 is provided with a slot 501. Screw holes are opened at the corresponding positions of the insertion strip 301 and the slot 501. It should be noted that in the present utility model, the cooling box 3 and the filter box 5 are set as detachable separate boxes. When assembling the two together, only need to vertically insert the insertion strip 301 provided on the outer wall of the bottom end of the cooling box 3 into the slot 501 provided on the outer wall of the top end of the filter box 5, and make the screw holes opened on their surfaces correspond to each other. At this time, then screw the fastening screw into the overlapping screw holes, and the assembly between the cooling box 3 and the filter box 5 can be completed. At the same time, when it is necessary to disassemble the two, the operator only needs to reverse-rotate and loosen the fastening screw again, and lift the entire cooling box 3 and the air delivery box 2 upward, and the rapid disassembly between the boxes can be completed. At the same time, the disassembled filter box 5 can also clean or replace the filter element of its internal filtering mechanism 6.

[0026] In this embodiment, as Figure 2 and Figure 4 shown, a clamping groove 502 is opened on the inner wall of the top end of the filter box 5, and a sealing rubber layer 503 is provided on the inner wall of the clamping groove 502. A clamping strip 302 is provided on the inner wall of the bottom end of the cooling box 3, and the clamping strip 302 is engaged with the clamping groove 502. It should be noted that since the cooling box 3 and the filter box 5 are detachable separate boxes, when the insertion strip 301 provided on the outer wall of the bottom end of the cooling box 3 and the slot 501 provided on the outer wall of the top end of the filter box 5 are engaged with each other, the clamping strip 302 provided on the inner wall of the bottom end of the cooling box 3 will also be inserted into the clamping groove 502 opened on the inner wall of the filter box 5 synchronously, and the clamping strip 302 will contact the sealing rubber layer 503 provided on the inner wall of the clamping groove 502 and extrude it outward, so that the sealing rubber layer 503 makes up for the gap between the clamping groove 502 and the clamping strip 302 through elastic deformation, thereby completing the sealing closure between the two, preventing the gas from leaking from the gap between the two during the waste gas treatment process, and ensuring the stability of the waste gas treatment process and the personal safety of the operator.

[0027] In this embodiment, as Figure 2 and Figure 3As shown in the figure, the cooling mechanism 4 is composed of a cooling pipe 401, a water storage tank 402, a semiconductor refrigeration sheet 403, a fixing bracket 404 and a water pump 405. The water storage tank 402 is placed on the top of the fixing bracket 404. The left and right ends of the cooling pipe 401 are inserted into the left and right sides of the water storage tank 402. The pipe body of the cooling pipe 401 horizontally penetrates through the inside of the cooling box 3. The water pump 405 is installed on the outer wall of one side of the cooling pipe 401. The semiconductor refrigeration sheet 403 is arranged on the inner wall of the water storage tank 402. It should be noted that in actual application, the waste gas generated by cement processing will have a certain amount of heat. When these high-temperature waste gases are introduced into the processing device for filtering operations, their excessive temperature will damage the filter element in the filtering mechanism 6. Therefore, in this utility model, a cooling box 3 is provided on the top of the filtering box 5 to cool these waste gases. The main method is to open the water pump 405 to introduce the cooling water inside the water storage tank 402 into the cooling pipe 401, so that the cooling water can circulate along the pipeline. When the waste gas is blown into the cooling box 3 by the fan 201, its hot waste gas will flow along the outer wall of the cooling pipe 401, thereby exchanging heat with the cooling water inside, and then realizing the cooling operation. The cooling water that takes away the heat of the waste gas will then flow back into the water storage tank 402 along the cooling pipe 401 again, and under the cooling of the semiconductor refrigeration sheet 403, it will return to its original temperature, realizing the circulating cooling operation.

[0028] In this embodiment, as Figure 6 shown, the filtering mechanism 6 is composed of a support frame 601, a first filter element 602, a second filter element 603 and a third filter element 604. The support frame 601 is fitted and placed on the inner wall of the filtering box 5. The first filter element 602, the second filter element 603 and the third filter element 604 are filled in the support frame 601 from top to bottom in sequence. It should be noted that the waste gas contains various harmful substances and suspended particles. After the cooling mechanism 4 in this utility model has completed the cooling operation on the waste gas, the waste gas will continue to flow downward into the filtering box 5 under the blowing of the fan 201, and successively pass through the filtering and interception of the first filter element 602, the second filter element 603 and the third filter element 604. The first filter element 602 will filter and intercept the dust and large particle substances contained in the waste gas, while the second filter element 603 can filter and intercept the tiny particles and some microorganisms in the waste gas. Finally, the third filter element 604 can adsorb and remove the harmful gases and odors in the waste gas, so that the waste gas can be purified into clean gas that can be discharged. After long-term use, the first filter element 602, the second filter element 603 and the third filter element 604 can also be cleaned or replaced.

[0029] In this embodiment, as Figure 1 and Figure 2As shown in the figure, the exhaust mechanism 8 is composed of a driving motor 801, a rotating shaft 802 and a spiral blade 803. The output end of the driving motor 801 is inserted into one end of the rotating shaft 802, and the other end of the rotating shaft 802 is rotatably connected to the inner wall of one side of the exhaust box 7. The spiral blade 803 is sleeved on the outer wall of the shaft body of the rotating shaft 802. It should be noted that when the gas after filtration and purification passes through the third filter element 604, it will flow downward into the exhaust box 7. At this time, the operator can start the driving motor 801 to drive the rotating shaft 802 inserted therewith, so that the spiral blade 803 sleeved on the outer wall of the rotating shaft 802 can perform a rotational motion, thereby conveying the clean gas around it to the exhaust pipe 9. During this period, the rotating spiral blade 803 can help the gas to be evenly distributed along the path, ensure that there is no locally high-concentration discharge during the discharge of the clean gas, and prevent the clean gas from escaping during the conveying process. The rotational action of the spiral blade 803 can also accelerate the flow rate of the gas around it, thereby ensuring the efficiency of the discharged gas.

[0030] The usage method and advantages of the present utility model: The connecting pipe with a quick-release joint structure, during use, the working process is as follows:

[0031] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown in the figure, first, when the operator passes the waste gas from cement processing production into the interior of the air delivery box 2 through the air inlet pipe 1, the fan 201 is started simultaneously, and its fan blades start to rotate, thereby driving the surrounding gas to blow downward into the cooling box 3. At the same time, the water pump 405 can be turned on to pass the cooling water in the water storage tank 402 into the cooling pipe 401, so that the cooling water can circulate along the pipeline. The waste gas will flow along the outer wall of the cooling pipe 401, thereby exchanging heat with the cooling water inside the pipe, and then achieving temperature reduction. During this period, the waste gas will continue to flow downward into the filter box 5 under the blowing of the fan 201, and successively pass through the filtration and interception of the first filter element 602, the second filter element 603 and the third filter element 604, removing the dust, large particle substances, some microorganisms, harmful gases and peculiar smells contained therein one by one, so that the waste gas can be purified into clean gas that can be discharged. When the filtered and purified gas passes through the third filter element 604, it will flow downward into the exhaust box 7. At this time, the operator can start the driving motor 801 to drive the inserted rotating shaft 802 and the spiral blades 803 provided on its outer wall to rotate synchronously, thereby transporting the surrounding clean gas towards the exhaust pipe 9. Then, when the solenoid valve is opened, the purified gas can enter the exhaust pipe 9 and be discharged outside the device. When the operator needs to clean or replace the filtering mechanism 6, the fastening screw can be loosened reversely first to release the position fixation between the slot 501 and the inserted bar 301, and the entire cooling box 3 and the air delivery box 2 are lifted upward, so that the cooling box 3 and the air delivery box 2 can be separated from the top of the filter box 5, and the boxes are separated from each other, thereby completing the rapid disassembly between the boxes.
