Description

Technical Field

[0001] The utility model relates to the technical field of purifier dust treatment, in particular to a purifier dust filtering and collecting device. Background Art

[0002] The purifier used for gas purification, also known as a gas purifier or gas purification device, is an important industrial equipment used to remove impurities in the gas and provide high-purity gas. The gas purifier removes impurities such as moisture, hydrocarbons, oxygen, nitrogen, etc. from the gas through various methods such as adsorption, chemical reaction, membrane separation, etc., thereby obtaining high-purity gas. High-purity gas is the key to the preparation of high-quality devices. The use of a gas purifier can ensure that the impurity content in the gas is lower than the set standard, thereby protecting production equipment from contamination and improving product yield and reliability.

[0003] Common gas purification uses solid particles to absorb impurities in the gas. As the use time increases, the solid particles often become pulverized. The tiny particles produced after pulverization will enter the subsequent process with the gas, resulting in the gas failing to meet the ultra-high purity requirements of 9N. In addition, the tiny particles will gradually accumulate and clog the filter, affecting the flow and pressure of the inlet and outlet gas, and failing to meet the use standards. Therefore, a purifier dust filtration and collection device is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a purifier dust filtering and collecting device, comprising a purification barrel body, an air outlet interface being provided at the bottom of the purification barrel body, a screen being provided inside the purification barrel body, the screen dividing the internal space of the purification barrel body into two upper and lower areas, which are a solid particle storage area and an airflow area respectively; a jet orifice plate located in the airflow area is provided inside the purification barrel body, a diversion orifice plate is provided on the jet orifice plate, and a deflector is provided on the diversion orifice plate.

[0005] Furthermore, the jet orifice plate includes a fixed plate, which is fixedly installed below the screen. The fixed plate surface is provided with annular equidistantly distributed perforations, and the perforations are arranged at an inclination.

[0006] Furthermore, the diversion orifice plate is arranged in a circular ring shape, and an arc-shaped sealing plate is arranged between the end of the diversion orifice plate away from the jet orifice plate and the inner wall of the purification barrel. The surface of the arc-shaped sealing plate is provided with wind-shielding isolation plates distributed equidistantly in a circular shape according to the diversion orifice plate.

[0007] Furthermore, the diversion orifice plate is provided with interactive holes distributed in an annular shape and at equal intervals.

[0008] Furthermore, a connecting plate is provided between one end of the deflector and the diversion orifice plate, and an air outlet channel is provided between the other end and the diversion orifice plate. The diameter of the deflector is narrowed from top to bottom.

[0009] Furthermore, a mounting plate located in the airflow area is provided in the purification barrel body, a particle filter located in the baffle is provided on the mounting plate, and a sedimentation chamber for collecting particulate powder is provided between the particle filter and the baffle.

[0010] The beneficial effects of the present invention are as follows: the present invention sets a jet orifice plate and an inclined perforation on the jet orifice plate, so that the gas entering the airflow area can form a turbine airflow, fully contact the inner wall of the purification barrel, and achieve initial dust filtration efficiency. At the same time, the setting of the diverter orifice plate and the deflector plate further refines and optimizes the flow path of the airflow, increases the time the gas stays in the airflow area, not only further increases the filtering effect, but also reduces the gas flow rate. A sedimentation chamber is set between the particle filter and the deflector plate to collect intercepted particulate powder, reduces the accumulation of dust on the filter medium, thereby extending the service life of the purifier and reducing the risk of clogging. Compared with the existing technology, the purification barrel body is provided with a screen, a jet orifice plate, a diverter orifice plate and a deflector plate and other structures to form a multi-level dust filtration system, and they work in coordination with each other to effectively capture and intercept tiny dust particles in the gas, ensuring that the filtered gas reaches a high purity standard and meets the purity requirements of 9N or higher.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0015] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0016] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0017] In the embodiment, Figure 1-2 A purifier dust filtering and collecting device is provided, comprising a purification barrel body 1, an air outlet interface 2 is provided at the bottom of the purification barrel body 1, a screen 3 is provided in the purification barrel body 1, the screen 3 divides the internal space of the purification barrel body 1 into two upper and lower areas, the two areas are respectively a solid particle storage area and an air flow area, the purification barrel body 1 is provided with a jet orifice plate 4 located in the air flow area, the jet orifice plate 4 is provided with a diversion orifice plate 5, the diversion orifice plate 5 is provided with a baffle 6, an air inlet interface is provided at the top of the purification barrel body 1, the gas enters the purification barrel body 1 from the air inlet interface, the gas is purified in the solid particle storage area, and then passes through the screen 3 into the air flow area, and the gas passes through the jet orifice Plate 4, the gas changes from vertical downward movement to eddy current rotation flow along the inner wall of the purification barrel body 1 and the diversion orifice plate 5. Under the action of centrifugation, tiny particles adhere to the inner side of the purification barrel body 1, realizing primary filtration, and then the gas passes through the interactive hole 9 and impacts the surface of the baffle 6. The gas and powder particles collide at the baffle, forming a gas-solid separation effect, thereby realizing secondary filtration, and the gas finally flows into the particle filter 13 from the gas outlet channel 11. The particle filter 13 adopts existing technology and can be purchased directly from the market, so it will not be repeated. Under the filtering action of the particle filter 13, three-stage filtration is realized, and the captured tiny particles are intercepted and concentrated in the precipitation chamber 14.

[0018] Reference Figure 1-2 , wherein the jet orifice plate 4 includes a fixed plate 41, the fixed plate 41 is fixedly installed below the screen 3, and the plate surface of the fixed plate 41 is provided with annular equidistantly distributed perforations 42, and the perforations 42 are inclined;

[0019] Through the above-mentioned structural setting, the jet orifice plate 4 is composed of a fixed plate 41 and inclined perforations 42 distributed in a circular shape and equidistant therefrom. The fixed plate 41 is firmly installed under the screen 3, ensuring the stability and reliability of the jet orifice plate 4 during the entire filtration and collection process. The inclined perforations 42 not only change the direct flow direction of the airflow, but also give the airflow a turbine-like flow, which fully allows the gas to contact the inner wall of the purification barrel body 1, thereby improving the dust collection efficiency.

[0020] Reference Figure 1-2 The diverter orifice plate 5 is arranged in a circular shape, and an arc-shaped sealing plate 7 is arranged between the end of the diverter orifice plate 5 away from the jet orifice plate 4 and the inner wall of the purification barrel body 1. The surface of the arc-shaped sealing plate 7 is provided with wind shielding isolation plates 8 distributed in an annular manner and equidistantly according to the diverter orifice plate 5. The diverter orifice plate 5 is provided with interactive holes 9 distributed in an annular manner and equidistantly.

[0021] Through the above-mentioned structural setting, the tiny particles intercepted by the gas after the first-stage filtration are deposited on the arc-shaped sealing plate 7. The diverter plate 5 is fixedly installed at the bottom of the jet plate 4 to further subdivide and guide the airflow generated by the jet plate 4. The wind-shielding isolation plate 8 further refines the flow path of the airflow, so that the airflow can be bent and dispersed multiple times when flowing through these plates, which helps to further reduce the airflow speed and give the tiny particles in the airflow more opportunities to settle or be captured.

[0022] Reference Figure 1-2 , wherein a connecting plate 10 is provided between one end of the baffle 6 and the diversion orifice plate 5, and an air outlet channel 11 is opened between the other end and the diversion orifice plate 5, and the diameter of the baffle 6 is narrowed from top to bottom;

[0023] Through the above-mentioned structural setting, as the air flow enters the space below the deflector 6 from the diversion orifice plate 5, the deflector 6, whose diameter gradually decreases, will force the air flow to turn and contract sharply, which not only further reduces the speed of the air flow, but also increases the chance of dust particles in the air flow colliding with the surface of the deflector 6. Due to inertia, dust particles are more likely to be captured during the collision and deposited in the collection area below the deflector 6.

[0024] Reference Figure 1-2 A mounting plate 12 located in the air flow area is provided in the purification barrel body 1, and a particle filter 13 located in the baffle 6 is provided on the mounting plate 12. A sedimentation chamber 14 for collecting particulate powder is provided between the particle filter 13 and the baffle 6.

Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
