Description

Technical Field

[0001] The present invention relates to the technical field of laboratory air purification, and particularly relates to a laboratory air purification device with a filter element dust removal function. Background Art

[0002] A laboratory air purifier (also known as a laboratory air purification machine or a laboratory clean screen) is mainly used to adsorb harmful aerosols generated during experimental operations such as centrifugation, stirring, mixing, and violent oscillation, reduce the concentration of aerosols in the air, and protect the safety of experimental operators.

[0003] However, for current traditional air purification devices, since they use filter elements to filter dust in the air, after long-term use, a large amount of dust will adhere to the surface of the filter elements. It is necessary for staff to open the device to clean the filter elements, which is rather troublesome and wastes a lot of time. At the same time, when the existing air purification devices are in use, since the filter elements intercept dust, the dust will not only adhere to the surface of the filter elements, but some dust will fall to the bottom of the air inlet and accumulate, which not only causes pressure on the purification of the device, but also easily causes blockage due to the accumulation of a large amount of dust. Summary of the Invention

[0007] Optionally, a telescopic rod is fixedly connected to the lower part inside the installation box body, and a connection flange is provided at the upper end of the telescopic rod; the telescopic rod is electrically connected to the control center of the installation box body.

[0008] Optionally, the driving motor is a stepping motor, and a connection disk is fixedly connected to the upper end of the main shaft of the driving motor; columnar protrusions arranged in a circle are provided at the lower end of the connection disk.

[0010] Optionally, the lower end surface of the second vibrating member is provided with paddles arranged in a circle, and the paddles of the second vibrating member and the paddles of the first vibrating member are arranged in a cross pattern; screw holes arranged in a circle are opened inside the second vibrating member.

[0011] Optionally, the filtering mechanism further includes: a filter element; a top cover is fixedly connected above the filter element, and a bottom cover is fixedly connected below the filter element.

[0012] Optionally, screw holes arranged in a circle are opened on the lower end surface of the bottom cover, and a sealing member is hermetically connected inside the bottom cover; an inclined surface with an inclination angle of 45 degrees is provided inside the sealing member.

[0013] Optionally, the collecting member is of an annular structure, and a snap ring is provided on the outer side of the upper end of the collecting member.

[0014] Beneficial effects For the air purification equipment according to the embodiments of the present invention, compared with the traditional air purification equipment, when it works normally, the telescopic rod jacks up, making the upper end surface of the connection disk parallel to the upper end surface of the sealing member, sealing the inside of the filtering mechanism, ensuring the airtightness of the filtering mechanism, and enabling the normal progress of the air filtering process; when removing ash from the filter element, the telescopic rod drives the driving motor to descend, and at the same time drives the connection disk to descend, making the upper end surface of the connection disk horizontal with the upper end surface of the first vibrating member, and at the same time the columnar protrusions on the lower end surface of the connection disk are inserted into the limiting grooves inside the first vibrating member. The driving motor drives the first vibrating member to rotate, making the paddles of the first vibrating member and the paddles of the second vibrating member interact with each other, causing the filter element to generate high-frequency vibrations, shaking off the dust attached to the filter element. In this way, the dust on the filter element can be processed without opening the installation box body, and the operation is simpler and faster.

[0015] In addition, as described above, during the vibration process, the dust shaken off and the dust accumulated at the bottom of the air inlet will fall onto the inner surface of the first vibrating member. Since the first vibrating member as a whole is driven by the driving motor to rotate, under the action of centrifugal force, the dust will slide outward along the inner surface of the first vibrating member inclined at a fifteen-degree angle, and finally fall into the interior of the collecting member through the collecting holes of the first vibrating member to be collected, thereby processing the dust inside the filter element, effectively preventing a large amount of dust from accumulating inside the filter element, increasing the working pressure of the device, and even causing the device to become blocked.

[0016] In addition, as described above, the collecting member is connected to the installation box body through a snap ring, which is more convenient for disassembly.

[0017] In addition, the top cover and the upper end surface inside the installation box body, and the first vibrating member is clamped inside the rotating groove of the installation box body. The above two connections directly produce a shock-absorbing effect through springs, so that the vibration of the vibration mechanism on the filtering mechanism can be transmitted to the installation box body with a smaller amplitude, reducing the impact of the vibration dust removal process on the installation box body.

[0018] In addition, a drying device is installed on the left side of the air inlet pipe to dry the gas entering the device, preventing the formation of scale on the surface of the filter element and corrosion of the filter element after the gas containing moisture enters the device, thereby ensuring the service life of the filter element.
