Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution cabinets, and in particular relates to a high-efficiency filtering and ventilation component for a machine tool power distribution cabinet. Background Art

[0002] The machine tool power distribution cabinet is an electrical control and protection device specially used for CNC machine tools.

[0003] The existing machine tool power distribution cabinet achieves active heat dissipation through fan rotation, effectively preventing overheating, protecting electrical components, maintaining electrical performance, extending equipment life, meeting protection level requirements, and complying with relevant standards and specifications, providing the necessary environmental conditions to support the stable and efficient operation of machine tools.

[0004] However, in the working environment of graphite processing, a large amount of graphite dust will be generated. The particles in the air can enter the cabinet through the ventilation holes of the distribution cabinet. Graphite dust is conductive and will pollute electrical components, reduce insulation performance, increase wear, affect heat dissipation, and even cause electrical faults such as short circuits. For this reason, we have proposed a high-efficiency filtering and ventilation component for machine tool distribution cabinets. Utility Model Content

[0005] The purpose of the utility model is to provide a high-efficiency filtering and ventilation component for a machine tool power distribution cabinet, so as to solve the problems existing in the background technology.

[0006] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0007] A high-efficiency filtering and ventilation component for a machine tool power distribution cabinet comprises a power distribution cabinet body, an air intake pipe is installed on the upper side of the rear end of the power distribution cabinet body, a fan is installed inside the air intake pipe, a plastic elbow is connected to the rear end of the air intake pipe, and a filtering component is provided on the upper end of the plastic elbow;

[0008] The filter assembly includes an air filter element, a connecting ring is fixed to the upper end of the plastic bent pipe, a plurality of evenly distributed connecting rods are fixed to the lower end of the connecting ring, a limiting ring is fixed to the lower end of each connecting rod, a rotating block is rotatably provided inside the limiting ring, an insertion rod is fixed to the upper end of the rotating block, the air filter element is sleeved on the outside of the insertion rod, rubber rings are provided at both the upper and lower ends of the air filter element, an annular groove is opened at the upper end of the connecting ring, the rubber ring on the lower side is rotatably provided inside the annular groove, a cap is threadedly connected to the upper end of the outer side of the insertion rod, and the upper wall inside the cap and the rubber ring on the upper side abut against each other.

[0009] Furthermore, a rotating rod is provided at the lower end of the rotating block, a plurality of evenly distributed fan blades are provided on the outside of the rotating rod, an L-shaped scraper rod abutting against the outside of the air filter element is provided on the outside of the cap, and a waste tray is provided on the upper end of the outer side of the plastic bent pipe.

[0010] Furthermore, a groove is provided on the lower wall of the waste tray, a discharge port is provided on the lower wall of the groove, a mounting port corresponding to the groove is provided on the upper end of the waste tray, and an L-shaped cover plate is provided inside the groove and the mounting port.

[0011] Furthermore, a lifting groove is provided on the outer side of the L-shaped cover plate.

[0012] Furthermore, an annular sealing strip is provided inside the air inlet pipe, and the annular sealing strip abuts against the front end of the fan.

[0013] Furthermore, the outer side of the cap is provided with anti-slip grooves.

[0014] The beneficial effects of the utility model are:

[0015] 1) The difference between the air inlet pipe and the plastic bent pipe makes it easier for workers to install the fan.

[0016] 2) The graphite particles in the air can be filtered through the air filter element, making the air entering the inside of the distribution cabinet body clean, thus preventing the components inside the distribution cabinet body from being affected.

[0017] 3) After the air enters the plastic curved pipe, it drives the fan blades to rotate together, thereby driving the rotating rod, rotating block, plug rod, cap and L-shaped scraper rod to rotate in turn, thereby cleaning the outside of the air filter element. This not only reduces the frequency of replacement by the staff, but also extends the service life of the air filter element.

[0018] 4) The graphite particles attached to the outside of the air filter can be collected by the waste tray, which can prevent the graphite particles from flying around and increase the cleaning work of subsequent staff.

[0019] 5) After the fan draws a large amount of air into the distribution cabinet body, the air pressure inside the distribution cabinet body is greater than the external atmospheric pressure because there is no direct exhaust place. In this way, the air can only be discharged at high speed through the gap on the distribution cabinet body. At the same time, it can also clean the graphite powder on the ground around the distribution cabinet body, which is convenient for the staff to handle later. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] Embodiment 1:

[0028] like Figure 1-Figure 3 As shown, the high-efficiency filtering and ventilation assembly of the machine tool power distribution cabinet includes a power distribution cabinet body 100, an air intake pipe 101 is installed on the upper side of the rear end of the power distribution cabinet body 100, a fan 102 is installed inside the air intake pipe 101, and a plastic bent pipe 103 is connected to the rear end of the air intake pipe 101, and a filter assembly is provided on the upper end of the plastic bent pipe 103;

[0029] The filter assembly includes an air filter element 104, a connecting ring 105 is fixed on the upper end of the plastic bent pipe 103, and a number of evenly distributed connecting rods 106 are fixed on the lower end of the connecting ring 105. A limiting ring 107 is fixed to the lower end of each connecting rod 106. A rotating block 108 is rotatably provided inside the limiting ring 107, and an insert rod 109 is fixed on the upper end of the rotating block 108. The air filter element 104 is sleeved on the outside of the insert rod 109, and rubber rings 110 are provided on the upper and lower ends of the air filter element 104. An annular groove 111 is opened on the upper end of the connecting ring 105, and the rubber ring 110 on the lower side is rotatably provided inside the annular groove 111. A cap 112 is threadedly connected to the upper end of the outer side of the insert rod 109, and the upper wall of the inner part of the cap 112 abuts against the upper rubber ring 110.

[0030] The power distribution cabinet body 100 is equipped with electrical components and provides necessary protection measures to ensure the safe and stable operation of the power system. The fan 102 can drive the air flow, the plastic elbow 103 and the air inlet pipe 101 can guide the air to flow into the power distribution cabinet body 100, and the air filter 104 can filter the air flowing into the plastic elbow 103, so that the air entering the power distribution cabinet body 100 is cleaner and will not affect the electrical components inside the power distribution cabinet body 100. The connecting ring 105 is convenient for connecting each connecting rod 106. The air filter 104 is installed, and each connecting rod 106 can also be installed with a limiting ring 107, the limiting ring 107 can be installed with a rotating block 108, the rotating block 108 is installed with an insert rod 109, the insert rod 109 can facilitate the installation of the air filter 104, the rubber ring 110 can make the air filter 104 better sealed after installation, the annular groove 111 can position the rubber ring 110, and facilitate the better installation of the air filter 104, and the cap 112 can clamp the air filter 104 to prevent the air filter 104 from having a gap, which affects the filtering of graphite particles in the air;

[0031] When the machine tool is used: start the fan 102, the fan 102 inhales the outside air, and after the air flows into the plastic bent pipe 103, the air will first pass through the air filter 104, and the air filter 104 can filter the graphite particles in the air, so that the air entering the inside of the distribution cabinet body 100 is clean, which can prevent the internal electrical components of the distribution cabinet body 100 from being affected. However, the existing distribution cabinet is not completely sealed, and there are some small gaps in the distribution cabinet. When a large amount of clean air enters the distribution cabinet body 100, due to the small gap, the exhaust air displacement is much smaller than the intake air displacement, which will cause the internal air pressure of the distribution cabinet body 100 to be higher than the external atmospheric pressure, so that the air is ejected at high speed from the gap, and then the graphite powder on the ground around the distribution cabinet body 100 is cleaned, reducing the subsequent work intensity of the staff.

[0032] In this embodiment, by starting the fan 102, outside air is sucked into the distribution cabinet body 100. During this process, the air filter 104 will filter the graphite particles in the incoming air, thereby preventing the graphite particles from affecting the electrical components inside the distribution cabinet body 100. At the same time, when the air is discharged through the gap of the distribution cabinet body 100, the surroundings of the distribution cabinet body 100 are indirectly cleaned, thereby reducing the subsequent cleaning intensity of the staff.

[0033] Embodiment 2:

[0034] Based on the first embodiment, other components of the filter and ventilation assembly are further described, such as Figure 1-Figure 3As shown, a rotating rod 200 is provided at the lower end of the rotating block 108, and a plurality of evenly distributed fan blades 201 are provided on the outer side of the rotating rod 200. An L-shaped scraper rod 202 abutting against the outer side of the air filter element 104 is provided on the outer side of the cap 112, and a waste tray 203 is provided on the upper end of the outer side of the plastic bent pipe 103.

[0035] A groove 204 is formed on the lower wall of the waste tray 203 , a discharge port 205 is formed on the lower wall of the groove 204 , an installation port 206 corresponding to the groove 204 is formed on the upper end of the waste tray 203 , and an L-shaped cover plate 207 is formed inside the groove 204 and the installation port 206 .

[0036] A lifting groove 208 is formed on the outer side of the L-shaped cover plate 207 .

[0037] An annular sealing strip 209 is disposed inside the air inlet pipe 101 , and the annular sealing strip 209 abuts against the front end of the fan 102 .

[0038] The outer side of the cap 112 is provided with anti-slip grooves.

[0039] In this embodiment, when the outside air flows into the plastic curved pipe 103, it will drive the fan blades 201 to rotate together, and the fan blades 201 will drive the rotating rod 200 to rotate, the rotating rod 200 drives the rotating block 108 to rotate, the rotating block 108 drives the insertion rod 109 to rotate, the insertion rod 109 drives the cap 112, and the cap 112 drives the L-shaped scraper rod 202 to rotate, so that the L-shaped scraper rod 202 can clean the outside of the air filter 104, and the graphite particles stuck to the outside of the air filter 104 will fall into the waste tray 203, so that the service life of the air filter 104 can be extended.

[0040] The staff can take out the L-shaped cover plate 207 through the pulling groove 208, and then sweep the graphite particles in the waste tray 203 into the groove 204, and finally discharge the graphite particles from the installation port 206.

[0041] The annular sealing strip 209 can seal the gap between the air inlet pipe 101 and the power distribution cabinet body 100 , thereby preventing graphite particles in the air from entering the inside of the power distribution cabinet body 100 through the gap.

[0042] The anti-slip grooves on the outside of the cap 112 can increase the friction between the cap and the staff's hands, making it easier and more convenient for the staff to turn the cap 112.
