Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a high-concentration oil mist filtering device. Background Technique

[0002] When filtering oil mist in the prior art, an electrostatic oil mist filtering device is often used. The electrostatic oil mist filtering device is an efficient air purification equipment, mainly used to treat the oil mist generated in industrial production, and is a common means for purifying the oil mist and fume of precision CNC machine tools and wire cut EDM machines. It has obvious advantages, without a filter element structure, and the subsequent consumable loss is small.

[0003] In the prior art, such an electrostatic oil mist filtering device generally has a pre-filter screen when in use, that is, a pre-filter. Its purpose is to filter out large-particle dust, so that the large-particle dust that can be easily filtered will not enter the subsequent electrostatic filtering work. However, this pre-filter may be blocked during the use of the device, and the cleaning frequency is higher than that of the electrostatic collection structure. Once the pre-filter screen is blocked and replaced, the smoke treatment work of the entire device needs to stop, which is likely to affect the processing work of the machine tool and the staff. Therefore, a high-concentration oil mist filtering device is needed to improve this problem. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-concentration oil mist filtering device to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A high-concentration oil mist filtering device, including a housing, an ionization chamber is arranged on one side inside the housing, an electrostatic collection chamber is arranged on one side of the ionization area inside the housing, and both the electrostatic collection chamber and the ionization chamber are arranged inside the housing in the form of drawers, so that the ionization chamber and the electrostatic collection chamber can be pulled out at any time when processing is required. A fume pre-treatment mechanism is fixedly arranged on one side of the housing surface. The fume pre-treatment mechanism includes an air inlet chamber, a filter chamber, a filter element, and a distribution valve plate. An air inlet chamber is fixedly arranged on one side of the housing surface. The air inlet chamber is "V"-shaped. A filter chamber is fixedly arranged on the outer surface of the air inlet chamber. A filter element is movably clamped inside the filter chamber. A distribution valve plate is movably arranged in the middle of the inner side of the air inlet chamber through a rotating shaft.

[0006] Preferably, limiting plates are fixedly arranged at both the upper end and the lower end inside the air inlet chamber. When the distribution valve plate rotates and contacts any one of the limiting plates, one side of the "V"-shaped air inlet chamber can be blocked, and at this time, this side of the "V"-shaped air inlet chamber can be sealed and no longer ventilated. At this time, the filter chamber on this side can be disassembled to replace or clean the filter, as well as clean the soot, oil droplets, etc. deposited due to gravity in the filter chamber on this side.

[0007] Preferably, a transmission mechanism for driving the distribution valve plate to rotate is arranged on the outer side of the housing. The transmission mechanism includes a fixed plate, a connecting rod, an electric push rod, and a transmission rod. The fixed plate is fixedly arranged at the lower end of the air inlet chamber. The lower end inside the fixed plate is movably arranged with the connecting rod through a bearing. One end of the connecting rod is fixedly provided with an electric push rod. One end of the rotating shaft where the distribution valve plate is located is fixedly provided with a transmission rod. The movable end of the electric push rod is movably connected to the transmission rod through a rotating shaft. The distribution valve plate can be driven to rotate through the transmission mechanism to control the sealing of one side of the "V"-shaped air inlet chamber.

[0008] Preferably, an air outlet chamber is fixedly arranged on the side of the housing away from the air inlet chamber. By connecting a centrifugal fan to the air outlet chamber, the air inside the housing can be pumped out to generate negative pressure inside the housing, and then the flue gas to be treated can be inhaled into the housing through the filter chamber and the air inlet chamber.

[0009] Preferably, handles are fixedly arranged on the outer surfaces of both the electrostatic collection chamber and the ionization chamber. The electrostatic collection chamber and the ionization chamber can be conveniently pulled out through the handles.

[0010] Preferably, a connecting flange is fixedly arranged on the surface of the air outlet chamber. The air outlet chamber can be conveniently externally connected to a pipeline and a centrifugal fan through the connecting flange.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. The present utility model is initially provided with two filter chambers. Initially, either side of the "V"-shaped air inlet chamber can be used for the entry of oil fume. At this time, the filter chamber and the filter element on this side can perform corresponding filtering work. When it is necessary to clean this filter chamber and the filter element, the electric push rod can be contracted or extended. Figure 3 As shown in the perspective view, the electric push rod should be contracted. When the electric push rod contracts, the rotating valve plate can be driven to move downward through the transmission rod, so that the upper filter chamber is conducted to continue the air intake work, while the lower filter chamber originally in use can be in a maintenance state. And at this time, disassembling the filter chamber will not affect the treatment of oil fume and oil mist of the entire device.

[0013] 2. The overall structure of the present utility model is simple and easy to operate. By simply controlling the extension and shortening of the electric push rod, different filter chambers can be quickly made to participate in the work, thus facilitating its popularization and use.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: a high-concentration oil mist filtering device, including a housing 1. On one side inside the housing 1, an ionization chamber 2 is provided. On one side of the ionization area inside the housing 1, an electrostatic collection chamber 3 is provided. Both the electrostatic collection chamber 3 and the ionization chamber 2 are arranged inside the housing 1 in the form of drawers, so that the ionization chamber 2 and the electrostatic collection chamber 3 can be withdrawn at any time when treatment is needed. On one side of the surface of the housing 1, an oil fume pre-treatment mechanism is fixedly provided. The oil fume pre-treatment mechanism includes an air inlet chamber 4, a filter chamber 5, a filter element 6, and a distribution valve plate 7. On one side of the surface of the housing 1, an air inlet chamber 4 is fixedly provided. The air inlet chamber 4 is in a "V" shape. On the outer surface of the air inlet chamber 4, a filter chamber 5 is fixedly provided. Inside the filter chamber 5, a filter element 6 is movably clamped. In the middle of the inner side of the air inlet chamber 4, a distribution valve plate 7 is movably provided through a rotating shaft.

[0021] At both the upper and lower ends inside the intake chamber 4, limiting plates 8 are fixedly arranged. When the distribution valve plate 7 rotates and contacts any one of the limiting plates 8, one side of the "V"-shaped intake chamber 4 can be blocked. At this time, this side of the "V"-shaped intake chamber 4 can be sealed and no longer ventilated. At this time, the filter chamber 5 on this side can be disassembled to replace or clean the filter, and to clean the soot, oil droplets, etc. deposited due to gravity in the filter chamber 5 on this side;

[0022] A transmission mechanism for driving the rotation of the distribution valve plate 7 is arranged on the outer side of the housing 1. The transmission mechanism includes a fixing plate 9, a connecting rod 10, an electric push rod 11, and a transmission rod 12. The fixing plate 9 is fixedly arranged at the lower end of the intake chamber 4. The lower end inside the fixing plate 9 is movably arranged with the connecting rod 10 through a bearing. One end of the connecting rod 10 is fixedly provided with the electric push rod 11. One end of the rotating shaft where the distribution valve plate 7 is located is fixedly provided with the transmission rod 12. The movable end of the electric push rod 11 is movably connected to the transmission rod 12 through a rotating shaft. Through the transmission mechanism, the distribution valve plate 7 can be driven to rotate to control the sealing of one side of the "V"-shaped intake chamber 4;

[0023] An air outlet chamber 13 is fixedly arranged on one side of the housing 1 away from the intake chamber 4. By connecting a centrifugal fan to the air outlet chamber 13, the air inside the housing 13 can be pumped out to create a negative pressure inside it. Then, the flue gas to be treated can be inhaled into the housing 1 through the filter chamber 5 and the intake chamber 4;

[0024] Handles 15 are fixedly arranged on the outer surfaces of both the electrostatic collection chamber 3 and the ionization chamber 2. Through the handles 15, the electrostatic collection chamber 3 and the ionization chamber 2 can be conveniently pulled out;

[0025] A connecting flange 14 is fixedly arranged on the surface of the air outlet chamber 13. Through the connecting flange 14, it is convenient to externally connect a pipeline and a centrifugal fan to the air outlet chamber 13.

[0026] Working principle: When using this device, the air inside the shell 13 can be extracted by connecting the centrifugal fan through the air outlet bin 13 to generate negative pressure inside, and then the smoke to be treated can be sucked into the shell 1 through the filter bin 5 and the air inlet bin 4. When the oil smoke enters the filter bin 5, part of the large particles of emulsion mist and dust will automatically fall into the filter bin 5 under the action of their own gravity, and the other part will be filtered by the filter element 6 inside the filter bin 5. Then the small particles of oil mist enter the ionization bin 2. In the ionization bin 2, under the action of the 12KV DC high voltage field, the oil mist will be discharged from the filter element 6. , ionize the oil smoke and generate a large number of free electrons and positive ions. When the oil-containing gas passes through a space with a large number of ions and electrons, the ions and electrons will attach to the dust and oil particles. The dust attached with negative ions and electrons will be negatively charged, and the dust attached with positive ions and electrons will be positively charged. The dust attached with charges will enter the electrostatic collection chamber 3 after coming out of the charged area. Under the action of the 6KV electric field force, the charged dust moves in the opposite direction of its polarity, and the dust is adsorbed on the electrode. The fine dust and oil mist are separated, and the clean air is directly discharged into the air through the fan under the action of the negative pressure of the centrifugal fan;

[0027] The preliminary filtering of the device is provided with two filter chambers 5. Initially, any side of the "V"-shaped air inlet chamber 4 can be used to allow the oil smoke to enter. At this time, the filter chamber 5 and the filter element 6 on this side can play a corresponding filtering role. When it is necessary to clean the filter chamber 5 and the filter element 6, the electric push rod 11 can be retracted or extended to Figure 3 The angle shown should be the retracted electric push rod 11. When the electric push rod 11 is retracted, the transmission rod 12 can drive the rotating valve plate to move downward, so that the filter bin 5 at the upper end is connected to continue the air intake work, and the filter bin 5 originally used at the lower end can be maintained, and disassembling the filter bin 5 at this time will not affect the oil smoke and oil mist treatment work of the entire equipment;

[0028] Moreover, the overall structure of the device is simple and easy to operate when in use. Different filter chambers 5 can be quickly put into operation by controlling the extension and contraction of the electric push rod 11, thereby facilitating popularization and use.
