Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas purification, and particularly relates to a waste gas purification device based on carbon molecular sieve base material. Background Technique

[0002] Carbon molecular sieve is a new type of adsorbent and an excellent non-polar carbon material. Its main component is elemental carbon, and its appearance is black columnar solid. Carbon molecular sieve can purify waste gas, and it has a relatively thorough purification effect. The existing structure for purifying waste gas using carbon molecular sieve is relatively simple. After long-term use, a large amount of dust particle impurities are easily attached to the surface of the carbon molecular sieve, reducing the waste gas purification efficiency.

[0003] The Chinese utility model patent with the publication number of CN210522246U, a waste gas purification device for carbon molecular sieve, includes an air inlet pipe and a purification pipe. The air inlet pipe and the purification pipe are communicated. A base is rotatably connected to the bottom of the inner wall of the purification pipe below the air inlet pipe. A rotating motor is installed at the bottom of the purification pipe, and the output shaft of the rotating motor is in transmission connection with the base. A metal mesh frame is fixedly connected to the top of the base, and carbon molecular sieve is filled inside the metal mesh frame. A driving motor is fixedly connected to one side of the inner wall of the purification pipe close to the base. The utility model relates to the technical field of waste gas treatment equipment. This waste gas purification device for carbon molecular sieve avoids the problem that a large amount of dust particles are easily accumulated on the surface after long-term use in the existing waste gas purification device for carbon molecular sieve, reducing the waste gas purification efficiency. The waste gas can be cooled after being blown by the fan blades, and at the same time, the dust particles generated during the waste gas purification process can be conveniently cleaned.

[0004] However, the above device has the following technical problems during actual use:

[0005] First, when the metal mesh frame rotates with the impurities on its inner wall to the side close to the fan blades in the above device, the air blown by the rotating fan blades will blow away the impurities adsorbed on the metal mesh frame. However, the air blown by the fan blades will blow the impurities to the inner wall on the side of the metal mesh frame far from the fan blades again, resulting in the impurities not being able to completely fall into the lower collection device, affecting the normal discharge of the impurities.

[0006] Second, in addition, in the above device, the collection device is communicated with the inside of the metal mesh frame. When the air blown by the fan blades passes through the inside of the metal mesh frame, under the disturbance of the air flow, the impurities in the collection device may enter the metal mesh frame again and adhere to the inner wall of the metal mesh frame, thus causing the blockage of the exhaust holes on the metal mesh frame and affecting the normal circulation of the subsequent air. Summary of the Utility Model

[0007] The present utility model provides an exhaust gas purification device based on a carbon molecular sieve base material, aiming to solve the problem that when the fan blade rotates in the above-mentioned device mentioned in the background art, the air blown out by it will blow the impurities onto the inner wall of the metal mesh frame far away from the fan blade again, affecting the normal discharge of the impurities into the lower collection device. At the same time, when the fan blade rotates, the air blown out by it will cause the impurities in the collection device to flow back into the metal mesh frame, and the impurities will block the metal mesh frame, affecting the normal circulation of the subsequent air.

[0008] The present utility model is implemented as follows. An exhaust gas purification device based on a carbon molecular sieve base material includes: a first air duct, and a second air duct connected to the first air duct. The second air duct is arranged on the top wall of the first air duct. A first motor is fixedly installed on the inner bottom wall of the first air duct, and a rotating plate is connected to the output end thereof. A first sieve mesh frame is fixedly connected around the top wall of the rotating plate. And a second sieve mesh frame is arranged in the second air duct. The second sieve mesh frame is fixedly connected to the rotating plate through a connecting column. Carbon molecular sieves are filled in both the first sieve mesh frame and the second sieve mesh frame. A cleaning mechanism, which has: a first cleaning component arranged inside the first air duct and fitting the inner peripheral wall of the first sieve mesh frame, and a second cleaning component arranged inside the second air duct and fitting the top wall of the second sieve mesh frame. And a collection device, which is arranged on the bottom wall of the first air duct and communicates with the inner cavity of the first sieve mesh frame. In this solution, the exhaust gas is discharged from the second air duct into the first air duct and needs to pass through the carbon molecular sieves in the second sieve mesh frame and the first sieve mesh frame in sequence for filtration. By arranging the first cleaning component in the first air duct and the second cleaning component in the second air duct, the first cleaning component cleans the impurities adhered to the inner peripheral wall of the first sieve mesh frame, and the second cleaning component scrapes the impurities on the top of the second sieve mesh frame. The impurities scraped by the second cleaning component fall into the first air duct (the first sieve mesh frame) along the second discharge groove, and together with the impurities cleaned by the first cleaning component, they fall into the discharge groove along the first discharge groove, and then enter the collection cavity along the discharge groove, completing the cleaning of the impurities, and avoiding excessive accumulation of impurities inside the first air duct, which affects the normal circulation of the subsequent purified exhaust gas.

[0009] In addition, the collection cavity in the collection box of this device communicates with the discharge groove. When the output end of the first motor controls the rotating plate to rotate to a specified position, the first discharge groove and the discharge groove are communicated, so as to facilitate the entry of impurities into the collection box. At the same time, when the first discharge groove and the discharge groove are misaligned, the collection cavity is not communicated with the first air duct, avoiding the impurities in the collection cavity from being agitated by the air blown out by the fan blade and flowing back into the first air duct again.

[0010] Among them, it should be noted that the interiors of the first and second sieve mesh frames are both hollow structures, and a carbon molecular sieve base material is filled in the hollow structures, and the carbon molecular sieve base material is used to adsorb, filter and clean the particulate impurities in the waste gas.

[0011] Preferably, the first cleaning assembly includes: a connecting plate fixedly installed on the inner wall of one side of the first air duct, and a side plate perpendicularly fixed to one end thereof. The bottom end of the side plate extends towards the rotating plate, and the top end extends below the second sieve mesh frame. A cleaning brush is fixedly installed on the side wall of the side plate close to the inner peripheral wall of the first sieve mesh frame, and a wind shield is also fixedly connected to the side wall of the side plate away from the cleaning brush; in this solution, the connecting plate is located above the first sieve mesh frame, one end of which is fixedly connected to the inner side wall of the first air duct, and the other end is fixedly connected to the side wall of the side plate erected above the rotating plate. A cleaning brush is provided on the side wall of the side plate below the connecting plate close to the first sieve mesh frame, and the bristles of the cleaning brush are attached to the inner peripheral wall of the first sieve mesh frame. When the output end of the first motor controls the rotation of the rotating plate, the rotating plate drives the annular first sieve mesh frame on its top wall to rotate synchronously. The cleaning brush sweeps on the inner peripheral wall of the continuously rotating first sieve mesh frame, and scrapes the impurities attached to the first sieve mesh frame onto the rotating plate.

[0012] It should be explained that a wind shield is also perpendicularly fixedly connected to the side wall of the side plate away from the connecting plate, and the height of the wind shield is the same as that of the side plate (or at least the same as the height of the first sieve mesh frame). The purpose of setting the wind shield is to cooperate with the side plate to form a wind shielding area (as Figure 5 shown, the rotating plate rotates counterclockwise). When the cleaning brush cleans the impurities, the impurities will fall onto the rotating plate and be located within this wind shielding area. The wind shield extends in a direction away from the fan blades, and it can block the airflow blown into the first sieve mesh frame by the fan blades, preventing the impurities from being blown to various positions inside the first sieve mesh frame, effectively ensuring that the impurities enter the discharge chute along the first discharge chute.

[0013] Preferably, the second sieve mesh frame includes: a frustum portion and an annular portion disposed around the outside of the frustum portion. The connecting column is fixedly installed on the bottom wall of the frustum portion, and a second discharge chute is provided on the annular portion; in this solution, when impurities adhere to the frustum portion, affected by the self-weight of the impurities and the subsequent scraping of the second scraper, the impurities will roll down the frustum portion onto the annular portion. At this time, as the second sieve mesh frame rotates, the impurities on the annular portion will be swept by the first scraper and fall into the first air duct along the second discharge chute, and fall into the wind shielding area formed by the above-mentioned wind shield and side plate, and finally fall onto the rotating plate, and are mixed with the impurities scraped off by the cleaning brush, so as to be discharged through the first discharge chute and the discharge chute subsequently.

[0014] Preferably, the second cleaning component includes: a first scraper fixedly connected to the side wall of the second air duct, the bottom wall of the first scraper being attached to the annular portion, and a second scraper fixedly connected to the end of the first scraper away from the inner wall of the second air duct, the second scraper being inclined and attached to the outer wall of the frustum portion; in this solution, by providing the first scraper, impurities on the annular portion can be scraped, and the second scraper can scrape impurities on the outer wall of the frustum portion. The impurities scraped by the second scraper will roll down along the inclined outer slope of the frustum portion onto the annular portion, and as the second sieve mesh frame rotates subsequently, the impurities will be discharged along the second discharge groove.

[0015] Preferably, the collection device includes: a first discharge groove opened on the rotating plate, and a discharge groove opened on the bottom wall of the first air duct. A mounting seat is fixedly installed on the bottom wall of the first air duct, and a placement groove is opened on its side wall. A collection box is detachably fixedly connected in the placement groove, and a collection cavity communicating with the discharge groove is opened on the top wall of the collection box; in this solution, a mounting seat is fixedly connected to the bottom wall of the first air duct corresponding to the discharge groove, and a collection box is placed in the mounting seat. The collection cavity at the top of the collection box is directly below the discharge groove. When the rotating plate rotates to a specified position, the first discharge groove, the discharge groove, and the collection cavity are sequentially communicated, and the impurities accumulated on the rotating plate will fall into the collection cavity for unified collection.

[0016] Preferably, an air cooling component is further provided in the first air duct, which has: a mounting plate fixedly connected to the inner wall of the first air duct on one side of the first sieve mesh frame, a second motor fixedly connected to the side wall of the mounting plate away from the rotating plate, a fan blade fixedly connected to its output end, and a dust-proof sieve mesh detachably connected inside the first air duct on the side of the mounting plate away from the rotating plate; in this solution, a second motor is provided on one side of the first sieve mesh frame. When its output end rotates, it will drive the fan blade to rotate. When the fan blade rotates, it will draw external air into the first air duct and finally blow it into the inside of the first sieve mesh frame, so as to contact the exhaust gas and cool the exhaust gas. The provided dust-proof sieve mesh can intercept and filter impurities and particulate suspensions in the external air, prevent damage to the second motor, and avoid blocking the exhaust holes on the outer peripheral wall of the first sieve mesh frame.

[0017] Compared with the prior art, the beneficial effects of the present utility model are: An exhaust gas purification device for a carbon molecular sieve base material of the present utility model:

[0018] 1. The first cleaning component cleans the impurities adhering to the inner peripheral wall of the first screening mesh frame, and the second cleaning component scrapes the impurities on the top of the second screening mesh frame. The impurities scraped by the second cleaning component fall into the interior of the first air duct (first screening mesh frame) along the second discharge chute, and together with the impurities cleaned by the first cleaning component, they fall into the discharge chute along the first discharge chute, and then enter the collection cavity along the discharge chute, completing the cleaning of the impurities, and avoiding excessive accumulation of impurities inside the first air duct, which affects the normal flow of the subsequent purified exhaust gas.

[0019] 2. In this device, the collection cavity in the collection box is communicated with the discharge chute. When the output end of the first motor controls the rotating plate to rotate to a specified position, the first discharge chute and the discharge chute are communicated, so as to facilitate the entry of impurities into the collection box. At the same time, when the first discharge chute and the discharge chute are misaligned, the collection cavity is not communicated with the first air duct, avoiding the impurities in the collection cavity from being stirred by the air blown by the fan blades and flowing back into the interior of the first air duct again.

The height of the wind shield 514 is the same as that of the side plate 512.

[0041] Furthermore, the second sieve mesh frame 4 includes: a frustum part 42 and an annular part 43 arranged around the outside of the frustum part 42.

The waste gas passes through the second sieve mesh frame 4 and the second sieve mesh frame 4 in sequence, and is discharged from the end of the second air duct 2 (away from the fan blade 133) inside the rotating plate 12.

[0049] The output end of the first motor 11 drives the rotating plate 12 to rotate. The rotating plate 12 drives the first sieve mesh frame 3 and the second sieve mesh frame 4 to rotate. The inner peripheral wall of the first sieve mesh frame 3 and the top wall of the second sieve mesh frame 4 are cleaned by the cleaning brush 513 and the first scraping plate 521 (the second scraping plate 522), so that the impurities on the second sieve mesh frame 4 fall onto the rotating plate 12 along the second discharge chute 44, and enter the collection cavity 66 together with the impurities scraped by the cleaning brush 513 through the first discharge chute 61 and the discharge chute 62;

[0050] Meanwhile, during the cleaning process of the waste gas, the output end of the second motor 132 drives the fan blade 133 to rotate. The fan blade 133 sucks the external air of the first air duct 1 into the first air duct 1 and blows it into the first sieve mesh frame 3 to be mixed with the waste gas, realizing the cooling treatment of the waste gas.

[0051] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
