Referring to fig. 1 to 2, a preferred embodiment of the present invention provides a ventilation and dust removal device, which aims to provide an air filter that improves dust removal efficiency and dust removal effect and meets the requirement of air filtration in a large ventilation volume.
The utility model provides a ventilation dust collector, shell 1 including the middle part link up, the upper and lower both ends of shell 1 constitute air intake 2 and air outlet 11, the installation limit is stretched out to 2 side circumference of shell 1 air intake, a vent department for fixing the device at the transport means, the left and right sides of shell 1 is connected with dust removal mouth 4 respectively, fixed mounting has the baffle 13 that the multiunit interval set up in the shell 1, baffle 13 is a plurality of installation cavities 14 with 1 inside equalling of shell, install air filter 3 that is used for separating air impurity in every installation cavity 14, the air that flows is got into by air intake 2, filter through air filter 3, the air that contains impurity is discharged through dust removal mouth 4, clean air is discharged through air outlet 11.
Specifically, in the invention, the air inlet 2 and the air outlet 11 are arranged on two sides of the shell 1 to realize area air inlet and outlet, the inside of the shell 1 is equally divided into a plurality of installation cavities 14 through a plurality of partition plates 13, so that the air filter elements 3 are installed in the installation cavities 14, and thus, the dust removal work can be simultaneously carried out when a plurality of groups of air filter elements 3 are installed side by side, thereby improving the dust removal efficiency and meeting the requirement of air filtration in large ventilation volume.
In the invention, the air filter element 3 comprises two symmetrically arranged guide plates 30 with the same structure, the two symmetrically arranged guide plates 30 are adopted in the scheme, and two sides of the guide plates 30 are in contact with the inner wall of the installation cavity 14, so that the two sides of the guide plates 30 can not only bear supporting force to ensure stable connection, but also prevent air flow from dispersing and ensure that the air flow flows along a preset channel. And the interval between two guide plates 30 and the 14 lateral walls of installation cavity is by air intake 2 to air outlet 11 one side crescent, because the air gets into from air intake 2, the air flow rate of air intake 2 is great relatively, the atmosphere is along the inside dust removal passageway 5 flow in-process of air filter 3, the gas velocity of flow can reduce, this scheme is through making the air flow along the dust removal passageway 5 flow in the air filter 3 that narrows down gradually, the velocity of flow can not obviously descend, thereby the speed that the air flows has increased relatively, the dust collection efficiency has been improved.
In the present invention, as shown in fig. 3, a dust removing channel 5 is formed between two air deflectors 30, the end of the dust removing channel 5 is communicated with a dust discharging channel 7, the dust discharging channel 7 is communicated with the dust removing opening 4, an air discharging channel 6 is formed between each air deflector 30 and the installation cavity 14, air enters from the air inlet 2, passes through the dust removing channel 5 to separate air containing impurities, and is discharged from the dust removing opening 4 through the dust discharging channel 7.
In the present invention, the guide plate 30 further includes a plurality of guide plates 300 arranged in parallel and at intervals, a guide channel 10 is formed between every two guide plates 300, and clean air enters the exhaust channel 6 along the guide channel 10. Specifically, the distance between each flow deflector 300 and the inner wall of the installation cavity 14 gradually increases along the direction from the air inlet 2 to the air outlet 11, that is, the flow deflector 300 inclines towards the air inlet 2. The air in the flow guide channel 10 flows obliquely backwards relative to the air in the dust removing channel 5, so that a high-pressure area which is higher than the pressure of the central part of the air flow of the dust removing channel 5 is formed at the joint of the flow guide channel 10 and the dust removing channel 5, the high-pressure area can push the lighter impurities (such as floccules) which are entrapped in the air flow of the dust removing channel 5 and are close to the flow guide channel 10 back to the position of the center of the dust removing channel 5, so that the lighter impurities cannot enter the flow guide channel 10, and the lighter impurities can continuously move towards the dust discharging channel 7 along with the air flow. And if the heavier impurities (such as sand grains) entrained in the airflow of the dust removing channel 5 reach the flow guide channel 10, the heavier impurities impact the inner wall of the flow guide channel 10 (namely the surface of the flow guide sheet 300), are ejected back to the center of the dust removing channel 5, and keep moving towards the dust exhaust channel 7 due to the inertia of the heavier impurities, but do not move towards the flow guide channel 10 at the oblique rear. In addition, if impurities (such as rainwater) with large moisture are mixed in the airflow of the dust removing channel 5 and reach the guide channel 10, the inner wall of the guide channel 10 is atomized and then pushed back to the central position of the dust removing channel 5 by the airflow, so that the dust removing effect is further improved, and the impurities cannot enter the exhaust channel 6 along the guide channel 10.
In this embodiment, the working principle of the ventilation and dust removal device is as follows: when air flow with a certain speed exists in the outside air, the air inlet 2 faces the air flowing direction, so that the outside air enters the air filter element 3 from the air inlet 2. The outside air first enters the dust removing channel 5, and impurities exist in the air entering the dust removing channel 5. Because each guide plate 30 has a certain inclination angle, a certain resistance is generated to the airflow, so that the flow velocity of the side wall in each installation cavity 14 is slow, the wall pressure in the dust removing channel 5 is increased, namely the static pressure is increased, the relative flow velocity of the central position of the airflow in the dust removing channel 5 is fast, and the static pressure is small. Therefore, the impurities such as the particles, floccules, water drops and the like entrained by the airflow of the dust removing channel 5 flow along the central line direction of the dust removing channel 5 under the action of the wall pressure. And under the action of unequal static pressure, the impurities are easier to approach the direction of the central line of the dust removal channel 5, so that the impurities are more favorable to move to the dust discharge channel 7 and then are discharged from the dust removal port 4.
Meanwhile, in the dust removing channel 5, when passing through the position of the flow guide channel 10, a part of air enters the flow guide channel 10 and flows out of the air exhaust channel 6, and the part of air is clean air. The specific principle is as follows: when the airflow enters the guide channel 10 from the dust removing channel 5, part of energy is lost, so that the airflow speed in the guide channel 10 is slower than that in the dust removing channel 5. Therefore, when the air flow containing the impurities in the dust removing channel 5 approaches the guide channel 10, the attraction force at the guide channel 10 is small, and the inertia of the movement of the impurities cannot be overcome, that is, the air flow speed in the dust removing channel 5 is higher than the air flow speed in the guide channel 10, so the impurities cannot enter the guide channel 10, and the clean air and the impurities can be separated by themselves. Wherein, the ratio or difference of the airflow speed in the flow guide channel 10 and the airflow speed in the dust removal channel 5 can be adjusted by adjusting the difference of the cross sections of the two channels and adding power sources such as fans and the like at the channel openings.
Therefore, the clean air without impurities can enter the exhaust channel 6 from the flow guide channel 10, and the impurities such as particulate matters, floating matters and the like are collected to the dust exhaust channel 7 along with the airflow of the dust exhaust channel 5 and then are exhausted from the dust exhaust port 4, so that the clean air and the impurities are separated by utilizing the air filter element 3. The integral device is simple in structure and convenient to install, clean air is stably provided through the device, accumulated impurities are prevented from blocking the device, the trouble of manually cleaning the air dust removal device is eliminated, manpower, material resources and financial resources are saved, and long-time normal work under the condition of not cleaning can be guaranteed.
In another embodiment provided in the present invention, the dust exhaust channel 7 includes two dust removing plates 50 and a cover plate 51 fixedly connected to the dust removing plates 50, the two dust removing plates 50 are respectively and fixedly connected to two flow deflectors 300 at a position of the air filter element 3 near the air outlet 11, the dust exhaust channel 5 is communicated with the dust exhaust openings 4 at two sides, and air containing magazines flows along the dust exhaust channel 5 and then gathers in the dust exhaust channel 7, and is exhausted back to the atmosphere through the dust exhaust openings 4.
As preferred, dust removal plate 50 includes the drainage portion unanimous with water conservancy diversion piece 300 shape and with drainage portion integrated into one piece and vertical ascending dust exhaust portion, two dust exhaust portion upside fixed mounting apron 51, the drainage portion is the same with the structure of water conservancy diversion piece 300 to be connected in the design of dust removal passageway 5, and reduce the installation of water conservancy diversion piece 300, can extend dust removal plate 50 simultaneously again, so that the air that contains impurity flows out.
In the present invention, as shown in fig. 4, the plurality of baffles 300 are fixed by a mounting bracket 8, and the mounting bracket 8 is fixed on the partition 13. Specifically, 8 bottoms of mounting bracket can be directly fixed with 14 inner walls of installation cavity, set up a plurality of draw-in grooves with the outer terminal surface matched with of water conservancy diversion piece 300 on the mounting bracket 8, with water conservancy diversion piece 300 joint in the draw-in groove one by one to make the both sides of water conservancy diversion piece 300 offset with installation cavity 14, so, guarantee the stable installation of water conservancy diversion piece 300. In addition, the mounting frame 8 and the flow deflector 300 can be integrally formed, and when the mounting frame 8 is used, the mounting frame 8 can be directly fixed in the mounting cavity 14, so that the assembly can be completed.
In another preferred embodiment of the present invention, a mounting bar 12 extends from the inner wall of the mounting cavity 14 near the side of the air inlet 2, and the mounting frame 8 is fixed on the mounting bar 12. Wherein, the shape of extension strip is unanimous with water conservancy diversion piece 300, not only can reduce the installation of water conservancy diversion piece 300, and the while can be convenient for mounting bracket 8 fixed, mounting bracket 8 sets up the middle part of guide plate 30, so, make water conservancy diversion piece 300 left and right sides atress even, whole assurance is stable.
In another preferred embodiment provided by the present invention, referring to fig. 6, the vertical section of the guide vane 300 is a wing shape, the guide vane 300 includes an outer convex flow guiding surface 300-1 and a smoothly arranged flow guiding surface 300-2, the flow guiding surface 300-1 and the flow guiding surface 300-2 are smoothly connected in a transition manner, the outer convex flow guiding surface 300-1 is a windward surface close to the dust removing channel 5, and the outer convex flow guiding surface 300-1 further increases airflow resistance compared with a plane, so that impurities are as less as possible close to the flow guiding channel 10. Meanwhile, the outward convex flow guide surface 300-1 enables a high pressure area to be formed above the flow guide surface 300-2 more easily, and the high pressure area between two adjacent flow guide surfaces 300-1 has a certain repulsion function, so that impurities are kept on the center line position of the dust removal channel 5. Meanwhile, the annular flow deflectors 300 enable the impurities to be stressed uniformly without eccentricity, so that the impurities can be better concentrated on the central line of the dust removal channel 5.
In another preferred embodiment of the present invention, as shown in fig. 7 and 8, the axial cross-section of the guide vane 300 is a rectangular, arc-shaped or polygonal plane (not shown), and the guide vane 300 with a regular and smooth shape has a simple manufacturing process compared to an airfoil-shaped guide vane 300, so that the guide vane 300 is easy to produce, use and install.

The shape of the convex block is not limited too much, and can be trapezoidal, triangular, circular, semicircular or other irregular shapes, and only a certain flow velocity blocking effect can be achieved. In addition, the raised blocks of the present invention can be arranged continuously or at intervals, wherein the continuously arranged raised blocks provide greater resistance than the intermittently arranged raised blocks, and can be arranged according to actual requirements and the size of the device in practical application.
In another preferred embodiment of the present invention, as shown in fig. 3, the spoiler strips 15 are arranged in a trapezoidal shape, i.e., the cross-section of the bump is trapezoidal. For the relatively irregular shape, the processing technology of the regular-shaped convex blocks is simpler, and the practicability is stronger. The contact area between the convex block with the rectangular cross section and the air inlet 2 of the air inlet pipe is the largest, so that the air flow is blocked most, and the energy loss of the air flow is also the largest. And the triangular or circular shape has smaller resistance and relatively smaller energy loss. Therefore, as a preferred scheme, the invention selects the convex block with the trapezoidal section, and the trapezoidal inclined plane is opposite to the air inlet 2, so that the higher blocking effect on the air flow is ensured, and the energy loss on the air flow is reduced.
