[0002] Organic waste gas refers to volatile organic compounds generated during industrial production. Waste gas treatment is generally achieved by thermal combustion, catalytic oxidation or adsorption. However, in the treatment of organic waste gas, the tail gas will contain solid particulate impurities, and directly discharging it will pollute the air.

[0003] In the prior art, organic waste gas is generally filtered after being treated. However, the filter components are prone to clogging, which affects the use effect. Based on this, the present invention designs an organic waste gas treatment device. Summary of the invention

[0009] An exhaust pipe, the exhaust pipe is connected to the side of the separation cylinder and fixedly connected to the fixed cylinder, and the exhaust pipe is used to filter the exhaust gas under the operation of the filter screen and then discharge the exhaust gas from the inner side of the separation cylinder;

[0010] A debris removal cylinder, the debris removal cylinder is fixed to a side of the fixed cylinder away from the exhaust pipe, and a filter material space is provided inside the debris removal cylinder;

[0011] A base, wherein the base fixes the fixing cylinder and the impurity removal cylinder simultaneously through a plurality of fixing components, and an impurity removal space is opened in the base;

[0012] The fixed cylinder is connected to a rotating assembly that allows the separation cylinder to enter the impurity removal cylinder and perform a swinging operation, thereby removing solid impurities deposited on the outside of the filter screen;

[0013] The impurity removal cylinder is connected with a cleaning component for frictionally cleaning the outer side of the filter screen.

[0014] In the above-mentioned organic waste gas treatment equipment, the rotating component includes a spiral portion opened on the inner wall of the fixed cylinder, and the spiral portion is spirally connected to a swivel. The swivel can rotate itself under the action of the spiral portion during translation. The swivel is coaxially sleeved on the outer side of the separation cylinder close to the exhaust pipe. The side of the separation cylinder away from the exhaust pipe is connected to a hydraulic cylinder, and the hydraulic cylinder passes through the filter material space and is fixed on the outer wall of the impurity removal cylinder.

[0015] In the above-mentioned organic waste gas treatment equipment, a discharge port is opened at the bottom of the impurity removal cylinder, and the discharge port is symmetrically connected to two rotating plates, and the two rotating plates are rotatably connected to the side of the discharge port through a rotating shaft respectively, and a buffer layer is connected to the side where the two rotating plates are close to each other, and the discharge port is sealed by rotating together through the buffer layer, and the discharge port is connected to the impurity removal space.

[0016] In the above-mentioned organic waste gas treatment equipment, the rotating ring is connected to the separation cylinder through a one-way bearing.

[0017] In the above-mentioned organic waste gas treatment equipment, the cleaning component includes a cleaning ring, the interior of the cleaning ring is hollow, the cleaning ring is made of an inflatable rubber material, the cleaning ring is provided with an inflation port and the inflation port is connected to a solenoid valve, the inflation port is connected to a pressurizing component, and the interior of the cleaning ring is inflated by the pressurizing component, so that the cleaning ring abuts against the outer wall of the filter screen, thereby realizing the cleaning effect of the cleaning ring on the filter screen.

[0018] In the above-mentioned organic waste gas treatment equipment, the pressurizing component includes an inflation cylinder, which is fixed on the impurity removal cylinder, and a pressurizing rod is inserted in the inflation cylinder. One end of the pressurizing rod is located in the inflation cylinder and is slidably connected to the inner wall of the inflation cylinder through a piston seal, and the other end of the pressurizing rod passes through the side wall of the inflation cylinder and is connected to the separation cylinder.

[0019] In the above-mentioned organic waste gas treatment equipment, the inflation cylinder is connected to a connecting pipe on the outer side, and two diverter pipes 1 are connected to the bottom of the connecting pipe.

In this way, after the hydraulic cylinder pulls the separation cylinder to the impurity removal cylinder, when the separation cylinder is pushed back into the fixed cylinder, the separation cylinder rotates, which can achieve the effect of shaking and cleaning the impurities on the filter screen and avoid clogging of the filter screen.

[0023] 2. Through the connection between the one-way bearing and the swivel, the separation cylinder does not rotate when entering the impurity removal cylinder, but rotates when leaving the impurity removal cylinder. This can cooperate with the friction rotation of the cleaning component on the surface of the filter screen to achieve a double cleaning effect, thereby improving the cleaning effect of the filter screen.

[0024] 3. The present invention is provided with a pressurizing assembly, and the pressurizing assembly is connected to the cleaning ring, so that when the separation cylinder enters the impurity removal cylinder, the cleaning ring is separated from the separation cylinder without affecting the sliding of the separation ring. When the separation cylinder is completely moved into the impurity removal cylinder, the cleaning ring is inflated and expanded by the pressurizing assembly, and abuts against the filter screen. The advantage of this is that when the separation cylinder leaves the impurity removal cylinder, the cleaning ring abuts against the filter screen. At this time, the separation cylinder is in a rotating state, which facilitates the cleaning of the filter screen by the inner side of the cleaning ring. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] Reference Figure 1-8 , an organic waste gas treatment device, comprising:

[0035] A separation cylinder 1, wherein a filter screen 2 is arranged in the middle of the separation cylinder 1;

[0036] The fixed cylinder 3, the separation cylinder 1 and the fixed cylinder 3 are coaxially arranged and rotatably connected;

[0037] An air intake pipe 4, which is connected to the top of the separation cylinder 1 and inputs exhaust gas into the interior of the fixed cylinder 3, and is connected to a solenoid valve;

[0038] An exhaust pipe 5 is connected to the side of the separation cylinder 1 and fixedly connected to the fixed cylinder 3. The exhaust pipe 5 is used to filter the exhaust gas under the operation of the filter screen 2 and then discharge the exhaust gas from the inner side of the separation cylinder 1;

[0039] The impurity removing cylinder 6 is fixed on the side of the fixed cylinder 3 away from the exhaust pipe 5. A filter material space is opened inside the impurity removing cylinder 6. A discharge port 11 is opened at the bottom of the impurity removing cylinder 6. The discharge port 11 is symmetrically connected to two rotating plates 12. The two rotating plates 12 are rotatably connected to the side of the discharge port 11 through a rotating shaft 14 respectively. A buffer layer is connected to the side where the two rotating plates 12 are close to each other, and the discharge port 11 is sealed by rotating together through the buffer layer. The discharge port 11 is connected to the impurity removing space.

[0040] A base 7, wherein the base 7 simultaneously fixes the fixing cylinder 3 and the impurity removal cylinder 6 through a plurality of fixing components 8, and an impurity removal space is provided in the base 7;

[0041] The fixed cylinder 3 is connected to a rotating component 9 which enables the separation cylinder 1 to enter the impurity removal cylinder 6 and perform a swinging operation, thereby removing solid impurities deposited on the outside of the filter screen 2. The rotating component 9 includes a spiral portion 91 opened on the inner wall of the fixed cylinder 3. The spiral portion 91 is spirally connected to a swivel 92. The swivel 92 can rotate itself under the action of the spiral portion 91 during translation. The swivel 92 is coaxially sleeved on the outer side of the separation cylinder 1 close to the exhaust pipe 5. A hydraulic cylinder 93 is connected to the side of the separation cylinder 1 away from the exhaust pipe 5. The hydraulic cylinder 93 passes through the filter material space and is fixed on the outer wall of the impurity removal cylinder 6. The swivel 92 is connected to the separation cylinder 1 through a one-way bearing 94.

[0042] The impurity removal cylinder 6 is connected to a cleaning assembly for frictionally cleaning the outer side of the filter screen 2. The cleaning assembly includes a cleaning ring 10. The interior of the cleaning ring 10 is hollow. The cleaning ring 10 is made of an inflatable rubber material. The cleaning ring 10 is provided with an inflation port and the inflation port is connected to an electromagnetic valve. The inflation port is connected to a pressurizing assembly 13. The electromagnetic valve can be closed after the gas is filled into the cleaning ring 10, so that the cleaning ring 10 always remains in an expanded state during the cleaning process. After the cleaning process is completed, the electromagnetic valve can be opened to release the pressure of the cleaning ring 10, and the interior of the cleaning ring 10 is inflated and expanded by the pressurizing assembly 13, so that the cleaning ring 10 abuts against the outer wall of the filter screen 2, thereby achieving the cleaning effect of the cleaning ring 10 on the filter screen 2;

[0043] The pressurizing assembly 13 includes an inflating cylinder 131, which is fixed on the impurity removal cylinder 6. A pressurizing rod 132 is inserted into the inflating cylinder 131. One end of the pressurizing rod 132 located in the inflating cylinder 131 is sealed and slidably connected to the inner wall of the inflating cylinder 131 through a piston 133. The other end of the pressurizing rod 132 passes through the side wall of the inflating cylinder 131 and is connected to the separation cylinder 1. The inflating cylinder 131 is connected to a connecting pipe 134 on the outer side. The bottom of the connecting pipe 134 is connected to two shunt pipes 135. The two shunt pipes 135 are rotatably connected to the rotating shaft 14, a pressure dividing channel 136 is provided inside the rotating shaft 14, and the other ends of the two pressure dividing channels 136 are connected to the cleaning ring 10 through the shunt pipe 2 137. The end surface of the separation cylinder 1 close to the pressure rod 132 is provided with a limiting groove 138 of an annular structure, and the cross-section of the limiting groove 138 is set to a "T" shape structure. The pressure rod 132 is movably connected in the limiting groove 138 through a limiting block 139, and the size of the limiting block 139 matches the limiting groove 138.

[0044] When the present invention is in use, the separation cylinder 1 is completely located inside the fixed cylinder 3, and the movable end of the hydraulic cylinder 93 is in an extended state. When the filter screen 2 is in normal use, the exhaust gas enters the separation cylinder 1 through the air inlet pipe 4, passes through the filter screen 2 in the separation cylinder 1, enters the inner side of the separation cylinder 1, and then is discharged from the exhaust pipe 5.

[0045] After the filter screen 2 has been used for a long time, a large amount of solid impurities will be attached to its outer part. At this time, the movable end of the hydraulic cylinder 93 is contracted, so that the separation cylinder 1 enters the impurity removal cylinder 6. At this time, the spiral part 91 cooperates with the swivel 92, so that the swivel 92 rotates in the positive direction, and the one-way bearing 94 allows the swivel 92 and the one-way bearing 94 to rotate in the positive direction. Therefore, the separation cylinder 1 only moves. At this time, the inner diameter of the cleaning ring is larger and is separated from the outer side of the filter screen 2. When the hydraulic cylinder 93 drives the separation cylinder 1 to completely enter the impurity removal cylinder 6, the hydraulic cylinder 93 drives the separation cylinder 1 to move in the reverse direction.

[0046] When the hydraulic cylinder 93 drives the separation cylinder 1 to move, the inflation of the inside of the cleaning ring 10 is achieved through the mutual sliding between the pressure rod 132 and the inflation cylinder 131, so that when the separation cylinder 1 completely enters the impurity removal cylinder 6, the cleaning ring 10 expands to the maximum state, and then when the separation cylinder 1 moves in the opposite direction, the one-way bearing does not allow the swivel ring 92 and the one-way bearing 94 to rotate relative to each other, which will drive the separation cylinder 1 to rotate, so the separation cylinder 1 will rotate and move at the same time, so that on the one hand, the solid impurities attached to the outside of the filter screen 2 can be loosened by shaking, and on the other hand, the cleaning effect can be achieved through the relative friction rotation between the cleaning ring 10 and the filter screen 2, and the outside of the filter screen 2 can be cleaned to the greatest extent. After the separation cylinder 1 completely enters the fixed cylinder 3, the solenoid valve of the cleaning ring 10 is opened, and the gas is released again, and the cleaning ring 10 returns to its initial state. The advantage of this is that when the cleaning ring 10 is converted from an expanded state to a deflated state, the dust attached to its surface will be cleaned. The state conversion of the stretching and relaxation on the surface of the cleaning ring 10 will cause the impurities attached to the surface to detach, avoiding the increase of its own volume, thereby facilitating the subsequent cleaning process.

[0047] The rotating assembly connected by two rotating shafts 14 rotates the two rotating plates 12 to open the discharge port 11, so that the solid impurities in the impurity removal space can be removed.

[0048] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
