[0002] Roots blowers are widely used in material transportation. Most gases contain different impurities such as water vapor and solid particles, so in practical applications, it is often necessary to set up a filter device to filter the gas.

[0003] However, the filtering device in the prior art generally only has a filter screen to filter the gas. For example, a Chinese patent with patent application number 201822216123.5 discloses a Roots blower inlet air filtering device, which includes an air storage tank and a filter box. The filter box has an air inlet at one end and an air outlet at the other end. A first filter screen, a second filter screen and a third filter screen are sequentially arranged inside the filter box from the air outlet to the air inlet. The air storage tank is connected to the air outlet of the filter box through a ventilation pipe.

[0004] Although the prior art similar to the above can filter impurities well by setting a filter net, the filtering effect on water vapor is average, and some water vapor will still enter the fan and affect the operation of the fan. Utility Model Content

[0005] Purpose of the utility model:

[0006] In order to overcome the problems existing in the prior art, the utility model provides a filtering and collecting device for gas containing solid particles and water vapor, solving the problem that the filtering device in the prior art can filter impurities well but has a general filtering effect on water vapor.

[0007] In order to solve the above problems, the utility model adopts the following technical solutions:

[0008] A filtering and collecting device for gases containing solid particles and water vapor, comprising a filter cylinder, a filter plate being arranged in the filter cylinder, the filter plate comprising an integrally connected mounting partition and a second filter plate arranged at both ends of the filter cylinder, the mounting partition and the second filter plate divide the filter cylinder into a condensation cavity located at the upper end and a filter cavity located at the lower end, an air inlet being arranged at one end of the filter cavity away from the second filter plate, an exhaust port being arranged at one end of the condensation cavity away from the second filter plate, a condensation coil being further arranged in the condensation cavity, the inlet end and the outlet end of the condensation coil both extending through the side wall of the condensation cavity to the outside of the condensation cavity, and a drain port being arranged in the filter cavity below the second filter plate.

[0009] Furthermore, the filter plate also includes a first filter plate extending downwardly toward the filter chamber at the connection between the mounting partition and the second filter plate, the end of the first filter plate away from the air inlet and the outermost filter holes of the end of the second filter plate close to the air inlet are located in the same axial direction of the filter cylinder, and there is a gap between the bottom of the first filter plate and the bottom wall of the filter chamber, and a guide tube parallel to the axial direction of the filter cylinder is also provided at the upper end of the filter chamber, the air inlet end of the guide tube extends through the air inlet to the outside of the filter cylinder, and the air outlet end of the guide tube extends to near the first filter plate.

[0010] Furthermore, three air inlets are equidistantly arranged, the three air inlets are equidistant from the filter plate, and three flow guide pipes are also equidistantly arranged in parallel.

[0011] Furthermore, a cleaning port is provided at one end of the filter cylinder away from the air inlet, and a cleaning window is hingedly connected to the cleaning port.

[0012] Furthermore, the side wall of the filter cylinder is symmetrically provided with two guide rails, the filter plate mounting partition and the second filter plate are slidably mounted in the two guide rails, and the size of the cleaning port corresponding to the filter plate position is larger than the size of the filter plate.

[0013] Furthermore, the exhaust port is provided with a cleaning agent interface.

[0014] Furthermore, the drain outlet is provided with a valve.

[0015] Working principle: Unfiltered gas enters from the air inlet end of the guide tube, passes through the guide tube to the first filter plate for preliminary filtration, and then passes through the first filter plate upward through the second filter plate to reach the condensation chamber. During this process, the first filter plate and the second filter plate filter out all solid impurities and part of the water vapor. The remaining gas is condensed by the condensation coil in the process of moving to the exhaust port in the condensation chamber and becomes water droplets, which fall down and are finally discharged from the drain port. Solid impurities gradually accumulate in the filter collection chamber, are cleaned through the cleaning window, and the filter plate is cleaned.

[0016] Beneficial effects: Compared with the prior art, the utility model has the following advantages:

[0017] 1. By setting up the filtering chamber and the condensing chamber, the solid impurities and water vapor in the gas can be filtered well at the same time.

[0018] 2. The filter plate extends downwardly toward the filter cavity at the connection between the partition plate and the second filter plate, and the outermost filter holes at one end of the first filter plate away from the air inlet and the second filter plate close to the air inlet are located on the same axial direction of the filter cylinder, so that the first filter plate can be continuously cleaned by water continuously condensed in the condensation cavity. Since the second filter plate filters the gas after passing through the first filter plate, the impurities on the second filter plate will be less than those on the first filter plate. Therefore, the frequency of cleaning the filter plate can be reduced as a whole. At the same time, when water or cleaning detergent is poured from the exhaust port, it can pass through the first filter plate, which is convenient for regular cleaning. When the cleaning window is opened for cleaning, the first filter plate and the second filter plate can also be pulled out together for quick cleaning in the external cleaning device.

[0019] 3. The gas outlet end of the flow guide pipe extends close to the first filter plate, so that the gas can reach the upper end of the first filter plate, reducing the situation where the gas passes through the gap at the lower end of the first filter plate.

[0020] 4. By setting up three guide pipes, the gas to be transported can be connected separately or simultaneously, which is suitable for the use requirements of different processing volumes. The processing volume can be adjusted within the range of 100-300%.

[0021] 5. By providing a cleaning port and a cleaning window at the cleaning port, the inside of the filter cylinder can be cleaned regularly.

[0022] 6. The filter plate is installed by setting a guide rail, so that the filter plate can be directly pulled out for cleaning when the cleaning window is opened to clean the inside of the cylinder. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0032] Any feature disclosed in this specification (including any additional claims, abstracts and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0034] like Figure 1-6 As shown, a filtering and collecting device for gas containing solid particles and water vapor comprises a filter cylinder 1, wherein a filter plate 2 is arranged in the filter cylinder 1, wherein the filter plate 2 comprises an integrally connected mounting partition 21 and a second filter plate 22 arranged at both ends of the filter cylinder, wherein the mounting partition 21 and the second filter plate 22 divide the filter cylinder 1 into a condensation cavity 11 located at the upper end and a filter cavity 12 located at the lower end, wherein an air inlet is arranged at one end of the filter cavity 12 away from the second filter plate 22, wherein an exhaust port 3 is arranged at one end of the condensation cavity 11 away from the second filter plate 12, wherein a condensation coil 4 is also arranged in the condensation cavity 11, wherein an inlet end 41 and an outlet end 42 of the condensation coil 4 both pass through the side wall of the condensation cavity 11 and extend to the outside of the condensation cavity 11, wherein a drain port 5 is arranged in the filter cavity 12 below the second filter plate 22. By arranging the filter cavity and the condensation cavity, solid impurities and water vapor in the gas can be filtered well at the same time.

[0035] In this embodiment, the filter plate 2 also includes a first filter plate 23 extending downward from the connection between the mounting partition plate 21 and the second filter plate 22. The outermost filter holes at one end of the first filter plate away from the air inlet and the end of the second filter plate 22 close to the air inlet are located in the same axial direction of the filter cylinder. There is a gap 6 between the bottom of the first filter plate 23 and the bottom wall of the filter cavity 12. The upper end of the filter cavity 12 is also provided with a guide tube 7 parallel to the axial direction of the filter cylinder 1. The air inlet end of the guide tube 7 extends through the air inlet to the outside of the filter cylinder 1, and the air outlet end of the guide tube 7 extends to near the first filter plate 23.

[0036] By adopting the above structure, the first filter plate can be continuously cleaned by utilizing the water formed by continuous condensation in the condensation chamber. Since the second filter plate filters the gas after passing through the first filter plate, the impurities on the second filter plate will be less than that on the first filter plate. Therefore, the frequency of cleaning the filter plate can be reduced as a whole. At the same time, when water or cleaning detergent is poured from the exhaust port, it can pass through the first filter plate, which is convenient for regular cleaning.

[0037] The setting of the gap 6 facilitates the passage of water droplets to the drain port, preventing them from accumulating at one end of the filter chamber near the air inlet. It also serves to allow solid impurities to pass through, so that simple cleaning can be completed without removing the filter plate.

[0038] The gas outlet end of the flow guide pipe extends close to the first filter plate, so that the gas can reach the upper end of the first filter plate, reducing the situation where the gas passes through the gap at the lower end of the first filter plate.

[0039] In this embodiment, three air inlets are arranged at equal distances from the filter plate 2, and three flow guide pipes 7 are also arranged at equal distances and in parallel. By setting three flow guide pipes, the gas to be transported can be connected separately or simultaneously, which is suitable for the use requirements of different processing volumes, and the processing volume can be adjusted within the range of 100-300%.

[0040] In this embodiment, a cleaning port is provided at one end of the filter cylinder 1 away from the air inlet, and the cleaning port is hinged with a cleaning window 9. By providing the cleaning port and the cleaning window at the cleaning port, the inside of the filter cylinder can be cleaned regularly.

[0041] In this embodiment, two guide rails 8 are symmetrically arranged on the side wall of the filter cylinder 2, and the mounting partition 21 of the filter plate 2 and the second filter plate 22 are slidably mounted in the two guide rails 8, and the size of the cleaning port corresponding to the position of the filter plate is larger than the size of the filter plate 2. By arranging the guide rails to mount the filter plate, it is convenient to directly pull out the filter plate for cleaning when opening the cleaning window to clean the inside of the cylinder.

[0042] In this embodiment, the exhaust port 3 is provided with a cleaning agent interface 31, so that the cleaning agent can be directly introduced through the exhaust port when cleaning the inside of the filter cylinder.

[0043] In this embodiment, the drain port 5 is provided with a valve 51, so that the valve can be opened to discharge the cleaning water after cleaning.

[0044] In this embodiment, the ratio of the entire cavity length L of the filter cylinder to the cylinder diameter is not less than 3.5, and the design flow rate is not higher than 10 m / s.

[0045] Working principle: unfiltered gas enters from the air inlet end of the guide tube 7, passes through the guide tube 7 to the first filter plate 23 for preliminary filtration, and then passes through the first filter plate 23 upward through the second filter plate 22 to reach the condensation chamber. During this process, the first filter plate 23 and the second filter plate 22 filter out all solid impurities and part of the water vapor. The remaining gas is condensed by the condensation coil in the process of moving to the exhaust port in the condensation chamber and becomes water droplets, which fall down and are finally discharged from the drain port. Solid impurities gradually accumulate in the filter collection chamber, are cleaned through the cleaning window, and the filter plate is cleaned.

[0046] The filtering device has a very good effect on conveying gas containing solid matter and high water vapor. It is installed at the front end of the air inlet of the Roots blower and is simple to make and easy to install.

[0047] The purpose of the above embodiments is to exemplarily reproduce and deduce the technical solution of the utility model, and to fully describe the technical solution, purpose and effect of the utility model. Its purpose is to make the public understand the disclosed content of the utility model more thoroughly and comprehensively, and it does not limit the protection scope of the utility model.

[0048] The above embodiments are not exhaustive enumerations based on the present invention, and there may be multiple other implementations not listed. Any replacement and improvement made without violating the concept of the present invention shall fall within the protection scope of the present invention.
