Description

Technical Field

[0001] The invention relates to the technical field of oil fume purification, in particular to high-stability anti-clogging impact flow type oil fume purification equipment. Background Art

[0002] With the rapid development of the catering industry, the problem of oil fume emissions has become increasingly prominent, posing a threat to the environment and human health. Therefore, it is necessary to use purification equipment to purify the oil fume before discharging it. It is generally divided into mechanical oil fume purification and impact flow oil fume purification. Impact flow oil fume purification technology is a new type of oil fume purification method. Its principle is to use the strong impact force generated by the impact of gas and liquid to make the oil fume particles fully contact and collide with the liquid, thereby realizing the capture and purification of the oil fume particles.

[0003] The existing impinging flow oil fume purification equipment filters the oil fume by spraying water. The oil fume contains a large amount of grease and tiny particles. These substances are sprayed out by the nozzle to form water mist when passing through the water channel, and collide and adsorb with the oil fume particles. As time goes by, the grease and particles will gradually accumulate on the nozzle and the inner wall of the water pipe, forming a thick grease layer. After long-term use, the nozzle will be clogged, which will affect the water spraying of the device, resulting in the oil fume unable to fully contact and collide with the oil fume, which will affect the purification effect of the device on the oil fume.

[0004] To this end, the present invention provides a highly stable anti-clogging impact flow type oil fume purification device. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The present invention provides a highly stable anti-clogging impinging flow type oil fume purification device, comprising a smoke collecting hood; an exhaust port is arranged on the front of the inside of the smoke collecting hood; a nozzle is installed at the bottom of the smoke collecting hood near the exhaust port; a processing mechanism is installed inside the nozzle; a water collecting tank is installed at the bottom of the smoke collecting hood near the nozzle; a water baffle is installed at the front of the smoke collecting hood near the nozzle; and a water supply mechanism is installed on the outside of the smoke collecting hood; The processing mechanism includes a fixed ring, a connecting spring and a scraper. The inner wall of the nozzle is fixedly mounted with a fixed ring, the bottom of the fixed ring is equidistantly mounted with connecting springs, and the inner wall of the nozzle at the bottom of the connecting spring is mounted with a scraper.

[0007] Preferably, a screw rod is installed at a central position in the nozzle, and a disc is installed on the outer side of the screw rod.

[0008] Preferably, a water inlet pipe is installed at the bottom of the water collecting tank, one end of the water inlet pipe is connected to the nozzle, and the other end is connected to the water supply mechanism.

[0009] Preferably, a return pipe is installed at one end of the bottom of the water collecting tank close to the water inlet pipe, one end of the return pipe is connected to the water collecting tank, and the other end is connected to the water supply mechanism.

[0010] Preferably, the water supply mechanism comprises a control box, a submersible pump and a liquid medicine tank, the control box is installed on the outside of the smoke hood, the submersible pump is installed inside the control box, and the liquid medicine tank is installed on one side of the top of the control box.

[0011] Preferably, two sets of sealing shells are installed on the outer wall of the nozzle.

[0012] Preferably, two groups of connecting plates are movably installed inside the nozzle, the connecting plates penetrate the interior of the nozzle, and one end of the connecting plates is connected to a sealing shell.

[0013] Preferably, a return spring is installed between the connecting plate and the nozzle.

[0014] 1. The beneficial effects of the present invention are as follows: the high-stability anti-clogging impact flow type oil fume purification equipment described in the present invention is used in conjunction with a water supply mechanism, a fixing ring, a connecting spring and a scraper. The liquid medicine is transported by the water supply mechanism to perform a preliminary flushing of the oil fume adhered to the inner wall of the nozzle. At the same time, the water pressure generated will impact the scraper, and the connecting spring will be deformed and the scraper will move. When the water supply mechanism stops supplying water to the inside of the nozzle and the scraper is not impacted, the scraper will reset under the action of the connecting spring. By moving the scraper back and forth, the oil fume adhered to the inner wall of the nozzle can be auxiliary scraped off to avoid blockage inside the nozzle caused by long-term oil fume adhesion, which will not affect the purification effect of the device on the oil fume.

[0015] 2. The high-stability anti-clogging impact flow oil fume purification equipment described in the present invention is used in combination with a sealing shell, a connecting plate and a reset spring. When the scraper moves downward under the action of water pressure, the bottom end of the scraper squeezes the connecting plate, and the reset spring compresses the connecting plate to drive the sealing shell to move, exposing the water spraying end of the nozzle. The nozzle can spray water and be used normally. When the device stops supplying water, the scraper resets without squeezing the connecting plate. The connecting plate will drive the sealing shell to reset under the action of the reset spring. When the bottom of the sealing shell is located at the water spraying end of the nozzle, the nozzle can be closed to prevent oil fume from entering the interior of the nozzle and attaching to it when the device is not in use, causing a large amount of oil fume residue to attach to it.

[0016] 3. The high-stability anti-clogging impact flow oil fume purification equipment described in the present invention is used in combination with a nozzle, a screw and a disc. The disc is moved so that the disc moves outside the screw. By adjusting the distance between the nozzle and the disc, the water sprayed by the nozzle and falling on the disc can be adjusted to produce a circular water mist spray range, which facilitates the oil fume to better contact with the water mist and achieve the purification effect.

[0019] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0020] Embodiment 1 The following is a further detailed description of the technical solution of the present invention in conjunction with the accompanying drawings and specific embodiments. Figures 1 to 7 , the high stability anti-clogging impact flow oil fume purification equipment provided by this application, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 7, comprising a smoke hood 1; an exhaust port 101 is provided on the front of the inside of the smoke hood 1, and the exhaust port 101 is connected to the exhaust duct at the rear, a nozzle 2 is installed at the bottom of the smoke hood 1 near the exhaust port 101, a processing mechanism 4 is installed inside the nozzle 2, a water collecting tank 103 is installed at the bottom of the smoke hood 1 near the nozzle 2, a water baffle 102 is installed on the front of the smoke hood 1 near the nozzle 2, and a water supply mechanism 3 is installed on the outside of the smoke hood 1; The processing mechanism 4 includes a fixed ring 401, a connecting spring 402 and a scraper 403. The inner wall of the nozzle 2 is fixedly installed with the fixed ring 401, the outer wall of the fixed ring 401 is fixedly connected to the inner wall of the nozzle 2, the bottom of the fixed ring 401 is equidistantly installed with connecting springs 402, and the inner wall of the nozzle 2 at the bottom of the connecting spring 402 is installed with a scraper 403, and the outer circle of the scraper 403 fits the inner wall of the nozzle 2.

[0021] Specifically, the device sucks the external oil smoke into the interior of the device, and at the same time the water supply mechanism 3 transports water to the nozzle 2, the nozzle 2 sprays water, and the oil smoke will first pass through the water mist generated by the nozzle 2. At this time, the water mist and the oil smoke collide, which can achieve the effect of filtering large molecular oil smoke, and then the purified oil smoke will be discharged through the exhaust port 101, the water sprayed by the nozzle 2 can be blocked by the water baffle 102, the water collection tank 103 can collect the sprayed water, and the treatment mechanism 4 is used to treat the oil smoke on the inner wall of the nozzle 2. When the water supply mechanism 3 transports water to the inside of the nozzle 2 to flush the inside of the nozzle 2, the water pressure will impact the scraper 403, and at this time the connecting spring 402 is deformed, and the scraper 403 moves. By moving the scraper 403, the oil smoke adhering to the inner wall of the nozzle 2 can be auxiliary scraped off to avoid long-term oil smoke adhesion causing the nozzle 2 Internal blockage, when the water supply mechanism 3 stops supplying water to the inside of the nozzle 2 and the scraper 403 is not impacted, the scraper 403 will reset under the action of the connecting spring 402. As long as the water supply mechanism 3 works to deliver water, the scraper 403 will move under the action of the water pressure. Because the oil smoke inside the nozzle 2 is purified by water spray, a small amount of oil smoke enters the inside of the nozzle 2 and pushes the scraper 403 when the water supply mechanism 3 supplies water. When the water supply is stopped, the scraper 403 will reset under the action of the connecting spring 402. This method is to avoid the accumulation of oil smoke attached to the inner wall of the nozzle 2 for a long time. Because the oil smoke inside the nozzle 2 is purified by water spray, a small amount enters the inside of the nozzle 2. The oil smoke is not attached to the inside of the nozzle 2 in large quantities. Only through the single movement of the scraper 403, the small amount of oil smoke attached to the inside of the nozzle 2 can be cleaned.

[0022] Please refer to Figure 5 A screw rod 201 is installed at the central position of the nozzle 2, and a disc 202 is installed on the outer side of the screw rod 201.

[0023] Specifically, in order to achieve the effect of generating circular water mist to better filter large molecular oil smoke, before use, the worker moves the disc 202 to move the disc 202 on the outside of the screw rod 201, and then installs the fixing nut on the outside of the screw rod 201 through the threaded structure on the outside of the screw rod 201, and limits the position of the disc 202 through the nut. By adjusting the distance between the nozzle 2 and the disc 202, the water sprayed by the nozzle 2 and falling on the disc 202 can generate a circular water mist, which is convenient for the later oil smoke to pass through the inside of the water mist, so that the oil smoke and the water mist can be better contacted, thereby achieving the effect of filtering large molecular oil smoke.

[0024] Please refer to Figure 1 and Figure 2 A water inlet pipe 104 is installed at the bottom of the water collection tank 103, one end of the water inlet pipe 104 is connected to the nozzle 2, and the other end is connected to the water supply mechanism 3.

[0025] Please refer to Figure 1 and Figure 2 A return pipe 105 is installed at one end of the bottom of the water collecting tank 103 close to the water inlet pipe 104. One end of the return pipe 105 is connected to the water collecting tank 103, and the other end is connected to the water supply mechanism 3.

[0026] Please refer to Figure 1 and Figure 2 The water supply mechanism 3 includes a control box 301, a submersible pump 302 and a liquid medicine tank 303. The control box 301 is installed on the outside of the smoke hood 1. The control box 301 consists of a box body and a filter plate. The box body stores water. The filter plate can filter the water transported by the return pipe 105. The submersible pump 302 is installed inside the control box 301. The input end of the submersible pump 302 is connected to the inside of the control box 301, and the output end is connected to the water inlet pipe 104. The liquid medicine tank 303 is installed on one side of the top of the control box 301.

[0027] Specifically, in order to achieve the filtering effect on large molecular oil smoke, an equal amount of liquid medicine in the liquid medicine tank 303 is transported to the inside of the control box 301 for mixing, and then the submersible pump 302 works. The submersible pump 302 transports the mixed liquid medicine water to the inside of each nozzle 2 through the water inlet pipe 104. The oil smoke adhering to the inner wall of the nozzle 2 can be washed by the liquid medicine transportation. At the same time, the sprayed water mist can filter the large molecular oil smoke passing through. Then the sprayed water will fall into the water collection tank 103 for collection, and then the oil smoke water will be transported to the inside of the control box 301 through the return pipe 105 for filtration and reuse.

[0028] Please refer to Figure 5 Two sets of sealing shells 5 are installed on the outer wall of the nozzle 2.

[0029] Please refer to Figure 6 Two groups of connecting plates 501 are movably installed inside the nozzle 2. The surfaces of the two groups of connecting plates 501 on the adjacent sides are inclined. The connecting plates 501 pass through the interior of the nozzle 2. One end of the connecting plates 501 is connected to a sealing shell 5. The inner wall of the bottom end of the sealing shell 5 near the outer side of the screw rod 201 is made of sponge material. When the two groups of sealing shells 5 are located outside the screw rod 201, the sponge material of the inner wall of the sealing shell 5 will fit the outer side of the screw rod 201, so that the sealing shell 5 and the screw rod 201 are in a sealed state.

[0030] Please refer to Figure 6 A return spring 502 is installed between the connecting plate 501 and the nozzle 2 , and the inner wall of the nozzle 2 is connected to the connecting plate 501 through the return spring 502 .

[0031] Specifically, in order to reduce the risk of oil smoke entering into and adhering to the interior of the nozzle 2 when the device is not in use, when the scraper 403 moves downward under the action of water pressure, the bottom end of the scraper 403 will squeeze the connecting plate 501, and one side of the connecting plate 501 will push the sealing shell 5 to move, and at the same time the reset spring 502 will deform. When the bottom of the two groups of sealing shells 5 move from the bottom of the nozzle 2, the water spraying end of the nozzle 2 will be exposed, and then the nozzle 2 can spray water and be used normally. When the device stops supplying water, the scraper 403 resets without squeezing the connecting plate 501. At this time, the connecting plate 501 will drive the sealing shell 5 to reset under the action of the reset spring 502. When the bottom of the sealing shell 5 is located at the water spraying end of the nozzle 2, the nozzle 2 can be closed to prevent oil smoke from entering into and adhering to the interior of the nozzle 2 when the device is not in use, causing a large amount of oil smoke residue to adhere.

[0032] Working principle: The submersible pump 302 works and transports the mixed liquid medicine water inside the control box 301 to the inside of each nozzle 2 through the water inlet pipe 104. The oil smoke adhering to the inner wall of the nozzle 2 can be washed by the liquid medicine transportation. At the same time, the water mist sprayed by the nozzle 2 can filter the large molecular oil smoke passing through. Then the sprayed water will fall into the water collection tank 103 for collection. The purified oil smoke will be discharged through the exhaust port 101, and then the oil smoke water will be transported to the inside of the control box 301 again through the inside of the return pipe 105 for filtration and reuse.

[0033] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
