Description

Technical Field

[0001] The invention relates to the technical field of electrical cabinets, and in particular to an automatic dust removal electrical cabinet used in a gypsum board production line. Background Art

[0002] Due to the large number of process technologies, the gypsum board production line requires control by electrical cabinets of various different control types. Such electrical cabinets are usually installed directly near the gypsum board production line to facilitate timely control of the start and stop of the production line.

[0003] Since the electrical cabinet is directly installed at the gypsum board production line, and the amount of dust in the gypsum board production line is relatively large, dust is easily accumulated inside the electrical cabinet that has been working for a long time, which causes the electrical parts to accumulate heat due to poor heat dissipation, thus affecting the operation of the electrical parts. Therefore, it is necessary to remove dust from the electrical cabinet in a timely manner. Currently, the commonly used dust removal electrical cabinets are usually directional purge type, that is, a fixed-direction blowpipe is set in the electrical cabinet, and the blowpipe blows laterally along the surface of the electrical parts to clean the dust on the surface of the electrical parts. Although this method can achieve partial dust removal, due to the volume difference of the electrical parts, a dead angle is formed in the blowing direction, making some areas difficult to be blown and affecting the dust removal effect.

[0004] Therefore, the existing directional blowing dust removal electrical cabinet has a dead corner because its blowing airflow is easily blocked by large-volume electrical components, which makes some areas difficult to blow and affects the dust removal effect. Summary of the invention

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] like Figure 1 As shown, the present invention provides an automatic dust removal electrical cabinet for a gypsum board production line, comprising:

[0044] The cabinet 1 has a plurality of horizontal rails for mounting electrical components;

[0045] The blowing pipeline 2 is arranged inside the cabinet 1. The blowing pipeline 2 includes a plurality of horizontal pipes 21 corresponding to the horizontal guide rails. A plurality of blowing heads 22 are arranged at equal intervals on the horizontal pipes 21. The blowing heads 22 face the electrical components on the horizontal guide rails.

[0046] The air supply pipeline 3 is arranged outside the cabinet 1 and extends to the inside thereof. The air supply pipeline 3 includes an air supply main pipe 31. The air supply main pipe 31 is provided with a plurality of branches and connected to a plurality of horizontal pipes 21 through valves so as to introduce high-pressure air into each horizontal pipe 21.

[0047] The steering mechanism 4 is arranged in the cabinet 1, and the steering mechanism 4 includes a plurality of movable rods 41, each movable rod 41 is connected to a plurality of blowing heads 22 in the same row, so as to drive the plurality of blowing heads 22 in the same row to synchronously adjust the blowing direction;

[0048] The dust collecting pipeline 5 is arranged outside the cabinet 1 and connected to the inside of the cabinet 1 to extract the dusty air from the cabinet 1 for filtration;

[0049] Among them, the movable rod 41 can move horizontally along its axial direction to control the horizontal swing of the blowing head 22 to adjust the horizontal blowing angle, and can rotate along the axis of the horizontal tube 21 to control the vertical swing of the blowing head 22 to adjust the vertical blowing angle, so as to perform multi-point spiral spray dust removal on the surface of electrical components and their connection points.

[0050] The electrical cabinet of this embodiment mainly utilizes the horizontal pipe 21 of the air blowing pipeline 2 to be arranged on the same layer as the horizontal guide rail, so that the blowing head 22 on the horizontal pipe 21 can be aligned with the electrical components installed on the horizontal guide rail, and the air supply main pipe 3 of the air supply pipeline 3 can spray out from the blowing head 22 through the horizontal pipe 21 to blow off the accumulated dust on the electrical components. At the same time, the movable rod 41 of the steering mechanism 4 can drive the blowing head 22 to swing horizontally and up and down, that is, the blowing head 22 can form a circular blowing area in the cabinet 1 to achieve comprehensive dust removal, and after the dust is blown off, the dust collecting pipeline 5 can suck out and filter the dust-containing air to avoid dust accumulation in the cabinet 1.

[0051] Compared with the existing dust removal electrical cabinet, the dust removal electrical cabinet of this embodiment can be equipped with a movable blowing head 22 on the horizontal tube 21 installed on the same layer as the horizontal guide rail, and the blowing head 22 is controlled by a movable rod 41, so that the blowing head 22 can swing horizontally as well as up and down to form a blowing trajectory that can move in a spiral direction, thereby forming a circular blowing area at the electrical components, achieving comprehensive dust removal of the electrical components, effectively reducing dust removal blind spots, and improving the dust removal effect.

[0052] Based on the above embodiments, the blowing head 22 needs to be able to move on the horizontal pipe 21, and the blowing head 22 is connected to the horizontal pipe 21. Based on this, the following preferred embodiments are provided.

[0053] like Figure 1 , Figure 2 As shown, the horizontal tube 21 is provided with a plurality of thin tube segments 211, the blowing head 22 is movably mounted on the thin tube segment 211, and both ends of the thin tube segment 211 are provided with a cover 212, and both sides of the blowing head 22 are movably assembled between the two covers 212;

[0054] A plurality of air holes 213 are evenly arranged on the side wall of the thin tube section 211 . The air holes 213 are connected to the blowing head 22 to introduce high-pressure air into the blowing head 22 and are sealed by the sealing cover 212 .

[0055] Specifically, the blowing head 22 can cover the thin tube segment 211 on the horizontal tube 21, so that the thin tube segment 211 can guide air into the blowing head 22 through the air hole 213, and because the thin tube segment 211 is thin, the blowing head 22 can move at the thin tube segment 211, and in order to avoid air leakage, the sealing cap 212 is used to movably seal the sleeves at both ends of the blowing head 22, thereby effectively avoiding air leakage.

[0056] Since the blowing head 22 can realize horizontal and vertical swinging under the action of the movable rod 41, a larger assembly gap is required between the blowing head 22 and the horizontal tube 21 to obtain a larger swing range. Based on this, the following preferred embodiments are provided.

[0057] like Figure 2 As shown, the blowing head 22 includes a mounting hole 221 penetrating the internal flow channel thereof, the mounting hole 221 is sleeved on the thin tube section 211 and can rotate along the axis of the thin tube section 211, the diameter of the mounting hole 221 is larger than the diameter of the thin tube section 211, and can rotate horizontally around the center of the thin tube section 211;

[0058] The hole end of the mounting hole 221 is movably sealed by a cover 212 , and two symmetrical covers 212 abut against each other to form two symmetrical movable holes 214 . The nozzle of the blowing head 22 passes through the movable hole 214 toward the electrical component and can move therein.

[0059] Specifically, there is a large gap between the mounting hole 221 of the blowing head 22 and the thin tube section 211, which enables the air hole 213 on the thin tube section 211 to effectively flow into the mounting hole 221, and the mounting hole 211 is connected to the inside of the blowing head 22, so that the air flow in the horizontal tube 21 is introduced into the blowing head 22 for spraying;

[0060] In order to further improve its sealing performance, two covers 212 are installed to partially cover the blowing head 22 so that the nozzle and the control end of the blowing head 22 are exposed through the movable hole 214, that is, during the movement of the blowing head 22, the nozzle and the control end do not affect the cover 212.

[0061] Since both sides of the blowing head 22 need to be movably sealed with the cover 212, in order to enhance the effect of the movable sealing, the following preferred embodiments are provided.

[0062] like Figure 2 As shown, two spherical surfaces 222 are formed on both sides of the blowing head 22 protruding outward, and the mounting hole 221 passes through the two spherical surfaces 222. The cover 212 is concave toward one side of the blowing head 22 and movably sleeved on the spherical surface 222, and the spherical surface 222 is sealed and slidably connected to the edge of the cover 212.

[0063] Specifically, the mounting hole 221 side of the blowing head 22 is set as a spherical surface 222, and the inner side of the cover 212 is concave. After being assembled with the spherical surface 222 of the blowing head 22, the blowing head 22 can move in any direction and continue to maintain a seal.

[0064] Based on the above embodiment, the movable rod 41 drives the blowing head 22 to rotate spirally for blowing. During this process, the distance between the connection point between the movable rod 41 and the blowing head 22 will change. Based on this, the following preferred embodiments are provided.

[0065] like Figure 2 , Figure 4 As shown, the movable rod 41 is provided with a plurality of telescopic members 42, and the two ends of the telescopic members 42 are rotatably connected to the movable rod 41 and the spray head 22, respectively, and the telescopic members 42 pass through the movable hole 214 away from the electrical member and can move therein;

[0066] In the process that the movable rod 41 moves horizontally along its axis and / or rotates around the axis of the horizontal tube 21, the telescopic member 42 adaptively telescopes.

[0067] Specifically, the telescopic member 42 can connect the movable rod 41 and the blowing head 22, so that during the movement of the movable rod 41, the telescopic rod 42 can be extended or shortened, and during this process, the extended or shortened telescopic member 42 can drive the blowing head 22 to move;

[0068] The telescopic member 42 is a spring-type telescopic member 42 , which has a reset capability, thereby having a pulling force to drive the blowing head 22 to move.

[0069] Since both ends of the telescopic member 42 need to be rotatably connected to the blowing head 22 and the movable rod 41 to adapt to the position change between the two fixed points, based on this, the following preferred embodiments are provided.

[0070] like Figure 4 As shown, the telescopic member 42 includes a telescopic rod 421, and ball rods 422 are rotatably provided at both ends of the telescopic rod 421, and the two ball rods 422 are respectively fixed on the blowing head 22 and the movable rod 41;

[0071] The rod end of the ball rod 422 facing the electrical component passes through the movable hole 214 and is fixed to the side of the blowing head 22 away from the nozzle. The diameter of the ball rod 422 is smaller than the diameter of the movable hole 214 and can move freely in the movable hole 214.

[0072] Specifically, the telescopic member 42 is composed of a telescopic rod 421 and two ball rods 422, and the telescopic rod 421 and the ball rod 422 are connected by a ball, thereby realizing a universal transmission, and the telescopic rod 421 is preferably a spring-type telescopic rod;

[0073] The ball head end of the ball rod 422 is placed outside the cover 212, and its rod portion passes through the movable hole 214 to be fixedly connected to the blowing head 22, thereby effectively increasing the gap between the ball rod 422 and the movable hole 214 to improve its movable adjustment range, thereby reducing the number of spray heads 22 set and simplifying the structure inside the cabinet 1.

[0074] Based on the above embodiments, the movable rod 41 needs to be driven to move horizontally along its axis and rotate around the horizontal tube 21 at a certain angle. Based on this, the following preferred embodiments are provided.

[0075] like Figure 2 As shown, the steering mechanism 4 also includes a sleeve 43, which is rotatably arranged at the end of each horizontal tube 21, and a horizontal electric push rod 431 is arranged on the sleeve 43, and the action end of the horizontal electric push rod 431 is fixedly connected to the movable rod 41 to push the movable rod 41 to move along its axis;

[0076] The horizontal electric push rod 431 can rotate along with the shaft sleeve 43 around the axis of the horizontal tube 21 to drive the movable rod 41 to rotate around the axis of the horizontal tube 21, thereby controlling the horizontal swing and / or up and down swing of the blowing head 22;

[0077] The plurality of shaft sleeves 43 work synchronously to drive the head portions of the plurality of blowing heads 22 to move.

[0078] Specifically, the sleeve 43 can rotate on the horizontal tube 21, thereby driving the horizontal electric push rod 431 to rotate, so that the movable rod 41 rotates around the axis of the horizontal tube 21. During this process, the horizontal electric push rod 431 can push or pull the axis of the movable rod 41 to move. The combination of the two movements can form a spiral motion trajectory, that is, the blowing head 22 spirally blows from the inside to the outside.

[0079] Based on the aforementioned embodiments, each sleeve 43 needs to be controlled to rotate on the horizontal tube 21. In order to make each sleeve 43 work simultaneously, the following preferred embodiments are provided.

[0080] like Figure 1 As shown, the steering mechanism 4 also includes a vertical electric push rod 44, the action end of which is provided with a vertical rack 441, the surface of the sleeve 43 is provided with tooth grooves 432 distributed around its axis, and the vertical rack 441 is installed in cooperation with the tooth grooves 432 of multiple sleeves 43 to drive the multiple sleeves 43 to rotate synchronously.

[0081] Specifically, a vertical electric push rod 44 is set at the upper or lower part (preferably the upper part) of the cabinet 1, and the vertical electric push rod 44 can drive the vertical rack 441 to reciprocate vertically, and the sleeve 43 cooperates with the vertical rack 441 through the tooth groove 432, thereby realizing the synchronous rotation of multiple sleeves 43, that is, enabling multiple spray heads 22 to work synchronously.

[0082] Since the operation of the blowing head 22 requires the air supply pipeline 3 to provide high-pressure air, the following preferred embodiments are provided.

[0083] like Figure 1 As shown, the gas supply pipeline 3 also includes a high-pressure gas storage bag 32, and the gas supply main pipe 31 is connected to the high-pressure gas storage bag 32 to introduce the high-pressure gas into each horizontal pipe 21;

[0084] A compressor 321 is provided on the high-pressure gas storage bag 32 , and the compressor 321 automatically inflates and pressurizes the interior of the high-pressure gas storage bag 32 after the pressure in the high-pressure gas storage bag 32 drops to a threshold value.

[0085] Specifically, the high-pressure gas storage bag 32 provides high-pressure gas, and the compressor 321 automatically replenishes the gas pressure in the high-pressure gas storage bag 32 when the gas pressure is too low, thereby avoiding the low flow rate of the air flow sprayed from the spray head 22 and making it difficult to achieve a good dust cleaning effect.

[0086] Since dust removal in the cabinet 1 also requires the dust collecting pipeline 5 to discharge the dust from the cabinet 1 and filter it to prevent the dust from accumulating in the cabinet 1 or being directly discharged from the cabinet 1 to affect the external environment, the following preferred embodiments are provided.

[0087] like Figure 1 , Figure 3As shown, the dust collection pipeline 5 includes a dust removal fan 51 fixed to the outside of the cabinet 1, a filter box 52 is provided on the air inlet side of the dust removal fan 51, and a dust removal pipe 53 is provided on the filter box 52, and the dust removal pipe 53 is connected to the inside of the cabinet 1;

[0089] Specifically, the dust removal fan 51 generates negative pressure in the filter box 52, and the dust blown out in the cabinet 1 can be sucked out through the dust removal pipe 53. In order to make the dust collection pipe 53 absorb dust evenly, a dust collecting hood 531 is provided at the end of the dust collection pipe 53, and the hood opening of the dust collecting hood 531 is provided with a mesh plate 532, so that each mesh opening of the mesh plate 532 has suction force to inhale dusty air.
