Description

Technical Field

[0001] This application relates to the technical field of filtration devices, and particularly to filtration and separation devices. Background Art

[0002] During the sintering process of process materials such as graphite, in order to ensure product quality, the sintering furnace must be strictly evacuated. Traditional sintering furnaces often face a series of technical challenges during the evacuation process. First, the air inside the furnace can cause oxidation of graphite parts at high temperatures, thus affecting the overall performance of the product. Therefore, in order to reduce oxidation, the sintering furnace usually needs to be evacuated to below 10 Pa. However, even in such a vacuum environment, when the temperature inside the furnace reaches a certain range, gaseous colloidal substances may still be generated in the hot atmosphere inside the furnace. These substances cause extremely serious pollution to the materials, not only affecting product quality but also potentially resulting in huge economic losses.

[0003] In addition, during the operation of existing evacuation systems, silicon carbide dust inside the furnace is easily inhaled. These dusts are carried out during the evacuation process, which may clog the filters of the evacuation system and even damage the entire system. Due to the accumulation of these dusts and the presence of gaseous colloidal substances, the maintenance and cleaning work of the evacuation system become complex and costly. This not only increases production costs but also may lead to a decrease in production efficiency.

[0004] Therefore, existing evacuation systems face the problem of being damaged due to inhaling impurities such as dust and gaseous colloidal substances during the sintering process of materials such as graphite. Summary of the Utility Model

[0005] In order to solve the problem in the prior art that the evacuation system is easily damaged due to inhaling too many impurities, this application provides a filtration and separation device, and the specific solution is as follows:

[0014] Preferably, a liquid cooling and heat dissipation mechanism is further included. The liquid cooling and heat dissipation mechanism is communicated with the cylinder body through the air inlet, and the liquid cooling and heat dissipation mechanism can cool the gas before the gas enters the cylinder body.

[0015] Preferably, the liquid cooling and heat dissipation mechanism includes a liquid cooling cylinder body and a liquid cooling component arranged inside the liquid cooling cylinder body for heat exchange between the liquid and the surrounding gas. The liquid cooling cylinder body includes an outer cylinder body and an inner cylinder body arranged inside the outer cylinder body. A liquid accommodation cavity is formed between the outer cylinder body and the inner cylinder body, and a coolant is arranged in the liquid accommodation cavity. A cylinder cover movably connected to the liquid cooling cylinder body is arranged at the cylinder opening of the liquid cooling cylinder body; the liquid cooling component includes two liquid cooling components and at least one heat dissipation blocking piece.

[0017] 1. By setting up the mounting plate to form an air inlet cavity and installing the filter element on the upper side of the mounting plate so that an air outlet cavity is formed between the filter element and the barrel wall of the cylinder body. On the one hand, it can avoid the filter element blocking the air inlet and causing impurities to accumulate at the air inlet, which affects the gas permeability. On the other hand, the mounting plate can isolate the air inlet cavity from the air outlet cavity, so that the gas must be filtered by the filter element before it can be exported, ensuring the purity of the exported gas. At the same time, through the cooperation of the fixing rod with the filter element cover and the mounting plate, the filter element is limited and fixed, avoiding the filter element being displaced due to suction force and blocking the air outlet. Therefore, this application can efficiently filter impurities in the gas and avoid damage to the vacuum pumping system caused by inhaling too many impurities;

[0018] 2. By setting up a horizontal limiting mechanism, on the one hand, it is convenient for positioning the filter element during installation, and on the other hand, it limits the filter element in the horizontal direction;

[0019] 3. By setting up a liquid-cooled heat dissipation mechanism, the gas is cooled in the liquid-cooled heat dissipation mechanism and then enters the cylinder body. The cooled gas can condense the gaseous colloids carried in the gas, which is beneficial for the filter element to fully filter and further reduces the impurities inhaled by the vacuum pumping system.

[0028] Referring to Figure 1 and Figure 2 , the filtration and separation device includes a filter element 4 with an air guiding through hole 41 in the center, a cylinder body 1 with an air inlet 11 and an air outlet 12 on the cylinder wall, and a cylinder cover 2 movably connected to the cylinder body 1. A horizontally arranged mounting plate 31 is fixedly provided in the cylinder body 1. An air inlet chamber is formed below the mounting plate 31. The filter element 4 is arranged above the mounting plate 31. An air outlet chamber is formed between the filter element 4 and the cylinder wall of the cylinder body 1. A filter element cover 42 is fixedly provided on the upper end surface of the filter element 4. The filter element cover 42 is detachably connected to the mounting plate 31 through a fixing rod 32. The mounting plate 31 is provided with at least one ventilation port 311. The air inlet chamber is communicated with the air guiding through hole 41 through the ventilation port 311. The mounting plate 31 isolates the air inlet chamber from the air outlet chamber. The air inlet 11 is communicated with the air inlet chamber, and the air outlet 12 is communicated with the air outlet chamber. The settings of the air inlet chamber and the air outlet chamber ensure the air permeability; the isolation of the air inlet chamber and the air outlet chamber by the mounting plate 31 ensures that the air must pass through the filter element 4, improving the filtration efficiency; the fixing rod 32 cooperates with the filter element cover 42 and the mounting plate 31 to prevent the filter element 4 from being displaced by suction during operation, ensuring the stability of the filtration work.

[0029] Referring to Figure 2 , the filtration and separation device further includes a horizontal limiting mechanism. The horizontal limiting mechanism is movably arranged above the mounting plate 31, and the filter element 4 is horizontally limited by the horizontal limiting mechanism.

[0030] Refer to in combination Figure 2 , the horizontal limiting mechanism includes at least three vertically arranged limiting plates, the limiting plates are movably arranged on the upper side of the mounting plate 31, and the limiting plates are evenly distributed along the inner wall of the filter element 4. The limiting plate 32 can limit the filter element 4 in the horizontal direction, and the limiting plate 32 is movably connected to the mounting plate 31, which is convenient for replacing the limiting plate 3 to adapt to filter elements 4 of different sizes.

[0031] Refer to in combination Figure 2 , at least one limiting block is fixedly arranged on the lower side edge of the limiting plate, the mounting plate 31 is provided with limiting holes 312 having the same number as and corresponding to the limiting blocks one by one, and the limiting blocks are matched with the corresponding limiting holes 312 to realize the detachable connection between the limiting plate and the mounting plate 31.

[0032] Specifically, one end of the fixing rod 32 is movably connected to the filter element cover 42, and the other end of the fixing rod 32 is movably connected to the mounting plate 31.

[0033] Optionally, one end of the fixing rod 32 is movably connected to the filter element cover 42, and the other end of the fixing rod 32 is fixedly connected to the mounting plate 31.

[0034] Optionally, one end of the fixing rod 32 is fixedly connected to the filter element cover 42, and the other end of the fixing rod 32 is movably connected to the mounting plate 31.

[0035] Refer to in combination Figure 1 and Figure 2 , the cylinder body 1 and the cylinder cover 2 are connected by a flange, and the cylinder body 1 is also hinged to the cylinder cover 2.

[0036] Refer to in combination Figure 3 , further comprising a liquid cooling and heat dissipation mechanism 5, the liquid cooling and heat dissipation mechanism 5 is communicated with the cylinder body 1 through the air inlet 11, and the liquid cooling and heat dissipation mechanism 5 can cool the gas before the gas enters the cylinder body 1.

[0037] Refer to in combination Figure 3 and Figure 4, the liquid cooling and heat dissipation mechanism 5 includes a liquid cooling cylinder body 51 and a liquid cooling component 52 disposed inside the liquid cooling cylinder body 51 for heat exchange between the liquid and the surrounding gas. The liquid cooling cylinder body 51 includes an outer cylinder body and an inner cylinder body disposed inside the outer cylinder body. A liquid accommodation cavity is formed between the outer cylinder body and the inner cylinder body. A coolant is provided in the liquid accommodation cavity. A liquid cooling cylinder cover 53 movably connected to the liquid cooling cylinder body 51 is provided at the cylinder opening of the liquid cooling cylinder body 51. The liquid cooling component 52 includes two liquid cooling sub-components and at least one heat dissipation blocking piece 525. Each liquid cooling sub-component includes a cooling pipe 522 and a fixing plate 521 having the same height as the inner cylinder body. The fixing plate 521 is vertically disposed inside the inner cylinder body and fixedly connected to the bottom of the inner cylinder body. There is a gap between any side edge of the fixing plate 521 in the vertical direction and the cylinder wall of the inner cylinder body. The cooling pipe 522 is fixedly provided on the installation side of the fixing plate 521, and heat dissipation fins 523 are fixedly provided on the side opposite to the installation side of the fixing plate 521. A coolant is provided in the cooling pipe 522.

The heat dissipation blocking piece 525 is vertically disposed in the interval area 524 and fixedly connected to the bottom of the inner cylinder body. The heat dissipation blocking piece 525 can prevent gas from passing through the interval area 524.

[0038] When the vacuum pumping system works, the high-temperature gas first enters the liquid cooling and heat dissipation mechanism 5, and the high-temperature gas is quickly cooled by the liquid cooling cylinder body 51 and the liquid cooling component 52. As the high-temperature gas cools, the gaseous colloids in the gas condense. The larger condensed colloids fall into the liquid cooling and heat dissipation mechanism 5, and the smaller condensed colloids and impurities such as silicon carbide dust follow the gas into the cylinder body 1 for further filtration. The gas enters the intake cavity from the first intake port 11, and then enters the air guiding through hole 41 through the air vent 311 of the mounting plate 31. Since there is a filter element cover 42 and the mounting plate 31 isolates the intake cavity and the exhaust cavity, the gas can only pass through the filter element 4 and enter the exhaust cavity, and finally is pumped into the vacuum pumping system from the exhaust port 12.

[0039] In summary, the filtration and separation device of the present application can efficiently filter the gas and thus prevent the vacuum pumping system from inhaling impurities. Therefore, the filtration and separation device of the present application can solve the problem in the prior art that the vacuum pumping system is easily damaged due to inhaling too many impurities.
