Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment devices, and in particular to a waste gas treatment device for processing Chinese herbal medicine slices. Background Art

[0002] In pharmaceutical factories, waste gas is often generated during the process. The waste gas generated during the production of Chinese herbal medicine pieces is a mixture of particulate impurities and toxic gases. Therefore, the waste gas needs to be purified before it is discharged to avoid the waste gas from polluting the atmosphere. The existing simple process for waste gas treatment mainly includes removing large particle dust through bag dust collectors, and then spraying plant spray liquid for chemical reaction and deodorization, and finally discharging the reacted gas. The existing bag dust collectors still have some problems during use, as follows:

[0003] The existing bag dust collector mainly separates the gas particles entering the interior through the internal filter assembly, and then collects and processes the dust particles separately. The separated exhaust gas is then removed from the odor through the spray assembly. However, the existing bag dust collector needs to use the dust particles to get into the filter holes of the filter plate to reduce the aperture after a period of use to achieve better dust removal. This method will lead to poor initial filtering effect. After waiting for the dust to block and reduce the aperture, it cannot last too long, otherwise it will cause the aperture to further reduce, and then cause the internal gas to circulate poorly. In this way, it is necessary to regularly clean the inside of the equipment. However, the existing cleaning method mainly removes dust from the filter plate by backblowing the gas from the exhaust gas output end. However, this method cannot quantitatively control the dust on the filter plate. After the dust stuck in the filter hole on the filter plate is cleaned, the equipment will return to its initial state, which will cause the equipment to be unable to always be in an efficient and reliable filtering state, resulting in unsatisfactory filtering effect. In addition, the existing filtering equipment also has the risk of dust explosion due to the presence of dust, resulting in poor applicability of the equipment. For this reason, we propose a waste gas treatment device for processing Chinese herbal medicines. Summary of the invention

All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0029] See also Figure 1-2 , a waste gas treatment device for processing Chinese herbal medicine slices, comprising an outer cylinder 1, a discharge port is arranged at the bottom of the outer cylinder 1, a first drain pipe 2 is fixedly installed at the middle of the top of the outer cylinder 1, a flow control valve 3 is fixedly installed on the first drain pipe 2, a water tank 4 is fixedly installed at one end of the flow control valve 3 through a short rod, a second drain pipe 5 is fixedly installed on the side of the flow control valve 3, a spray plate 6 is fixedly installed at the bottom end of the second drain pipe 5, a central shaft tube 7 is fixedly and movably installed in the middle of the outer cylinder 1, a control component 8 is movably installed in the central shaft tube 7, a filter component 9 is fixedly installed on the control component 8, and a cleaning control component 10 is movably connected to the outside of the central shaft tube 7;

[0030] Compared with the prior art, the present application is provided with a plurality of filter components 9 arranged at even intervals, so that the exhaust gas can pass through the plurality of filter components 9 for multi-stage particle removal, and the filter components 9 are rotated during the particle separation process, so that it can be ensured that the gas does not flow directly and smoothly inside the outer cylinder 1, but has a certain resistance. This resistance can reduce the gas flow to a certain extent, so that the particulate impurities mixed therein can be separated out in the neutral stage, and at the same time will not affect the normal separation function of the device. During the rotation of the filter component 9, the dust particles that clog the filter holes thereon will be cleaned in real time under the action of the cleaning control component 10, so that the filtering effect of the filter component 9 can be guaranteed at any time. Compared with the existing device, there is no need to rely on the pore size blocking by particulate impurities to increase the filtering effect, which greatly ensures the device's removal effect of particulate impurities in the exhaust gas, and also avoids the need for frequent shutdowns for dust backblowing cleaning. At the same time, a control disk 83 is provided, and the control disk 83 is The connecting rod 107 is installed and connected, so that the connecting rod 107 can be driven to move horizontally by operating the rotating shaft rod 81, so that the slide plate 106 can be driven to move horizontally on the side frame 105, thereby controlling the distance between the side frame 105 and the baffle plate 96. The distance between the two can control the amplitude of the rotation of the baffle plate 96 under the obstruction of the slide plate 106. The closer the distance, the greater the amplitude. In this way, when the baffle plate 96 rotates away from the slide plate 106, the greater the force of the rotation will be, so that the impact force on the support rod 93 will be greater, and the force of the support rod 93 hitting the filter plate 92 can be controlled. Such a structure can not only realize the cleaning of dust particles on the filter plate 92 at any time without stopping for backblowing, which greatly improves the use effect of the device, but also can choose whether to clean the filter plate 92 in real time or in stages according to the current use situation, and the cleaning force and effect of the staged cleaning of the filter plate 92 can also be easily controlled, which greatly improves the controllability and use effect of the device.

[0034] In this embodiment, it should be noted that the spray plate 6 can be used to perform spraying treatment simultaneously when the device separates and removes particulate impurities in the exhaust gas. This not only allows the dust impurities to settle directly inside the outer cylinder 1, but also avoids the dust particles being raised again under the condition of continuous external exhaust gas input, thereby eliminating the hidden danger of dust explosion, and at the same time, it can also effectively clean the dust inside the outer cylinder 1 to ensure the dust removal effect.

In this way, when the filter assembly 9 needs to be cleaned, the protruding rod 82 and the control disk 83 can be driven to move by rotating the shaft 81. Since the cleaning control assembly 10 and the control disk 83 are connected, the cleaning control assembly 10 can be driven to move under the movement of the control disk 83, and then the cleaning degree of the filter assembly 9 can be controlled by controlling the distance between the filter assembly 9 and the cleaning control assembly 10, thereby achieving the effect that the device can clean the filter assembly 9 in real time, thereby improving the use effect of the device.

The support rod 93 is an elastic plastic tube. The connecting end of the rotating rod 94 located on the inner ring of the ring block 91 is provided with a coil spring. In this way, the filter plate 92 can be driven to rotate during the rotation of the ring block 91, and then the baffle 96 can be driven to rotate. When it is necessary to clean the surface of the ring block 91 with particulate impurities, the cleaning effect can be controlled by controlling whether the cleaning control component 10 is in contact with the baffle 96 and the degree of contact, thereby ensuring that the device can control the effect of cleaning the filter plate 92 at any time.
