Description

Technical Field

[0001] The invention relates to the technical field of ventilation and filtering equipment, and in particular to a ventilation and filtering device for an electric shovel electrical room. Background Art

[0002] Open-pit mines are operated by mining directly on the ground. As the mainstream mining equipment in open-pit mining, electric shovels are mainly used for stripping and loading ore materials. Therefore, dust is splashed everywhere in the working environment, and the air pollution is serious. In order to prevent external dust from entering the electrical room, ensure that the air passing through the electrical room is clean, and protect electrical equipment, the electrical room of the electric shovel is usually equipped with ventilation and filtering equipment.

[0003] The ventilation and filtering devices in the existing electric shovel electrical room are mostly filter elements, which generally have the following problems: 1. Since the electric shovel works 24 hours a day and the dust concentration in the pit is high, the filter element will be blocked and the filtering performance will decrease, and the filter element needs to be replaced or cleaned frequently; 2. The ventilation and filtering devices in the existing electric shovel electrical room are closed, which causes the filtered dust to accumulate inside the device and is difficult to remove; 3. The ventilation and filtering devices in the existing electric shovel electrical room are installed on the top of the shed, and are surrounded by pipelines and electronic facilities. The internal space is small, making it difficult for maintenance personnel to inspect and maintain. Maintenance personnel need to climb to work, remove the pressure cover, and then take out the filter element, which greatly increases the workload of maintenance personnel; 4. The existing ventilation and filtering devices in the electric shovel electrical room do not have air volume sensors. The electric shovel operators can only determine the air volume by their own perception, and cannot timely understand the operation of the ventilation and filtering devices, which easily leads to abnormal temperature in the electrical room.

[0035] 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 in conjunction with the accompanying drawings.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0038] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0039] Example 1

[0040] Reference Figure 1~Figure 4 , which is the first embodiment of the present invention, provides a ventilation and filtering device for an electric room of an electric shovel, the device comprising a filtering unit 100, comprising a containing component 101, a plurality of groups of filtering components 102 arranged inside the containing component 101, a dust removal component 103 arranged on each group of filtering components 102, an air pump 104 arranged at the top of the containing component 101 and connected to the dust removal component 103, a discharge pipe 105 arranged at the bottom of the containing component 101, an air inlet component 106 arranged at a side of the containing component 101, and an air outlet component 107 arranged at the other side of the containing component 101;

[0041] During use, the air inlet component 106 draws the dusty air from the outside into the containing component 101, and the dusty air is filtered and purified by the filter component 102 to separate the dust from the air. The purified air is transported to the electrical room through the air outlet component 107, and the dust remaining on the filter component 102 can be removed by the dust removal component 103 to play a dust removal role. After the removed dust is deposited and falls to the bottom of the containing component 101, it can be discharged to the outside of the containing component 101 through the discharge pipe 105, and the dust will not accumulate and clog the containing component 101, affecting the normal filtering work;

[0042] The collecting unit 200 includes a driving motor 201 located at the center of the bottom of the containing part 101, a collecting part 202 of a three-pronged structure arranged above the driving motor 201 and located at the bottom of the inside of the containing part 101, a transmission part 203 correspondingly arranged on each fork of the collecting part 202, and a pushing part 204 arranged on each group of the transmission parts 203;

[0043] During use, the driving motor 201 drives the collecting component 202 to rotate, and the rotating collecting component 202 will push and collect the dust that has fallen to the bottom of the containing component 101, so as to prevent it from being left in a flat manner at the bottom of the containing component 101 and causing accumulation. At the same time, the collecting component 202 can push the dust to the discharge outlet of the discharge pipe 105 while rotating, so as to facilitate the subsequent discharge of the dust from the discharge pipe 105. When the collecting component 202 rotates, the pushing component 204 will also push the dust that is scooped up and pushed by the circular rotation of the collecting component 202 along the transmission component 203 laterally outward, so that the dust is collected and pushed to the bottom edge of the containing component 101, and the top inlet of the discharge pipe 105 is just below the edge of the containing component 101, so that the dust can be discharged conveniently.

[0044] The dredging unit 300 includes a fixing component 301 disposed in the discharge pipe 105, a stirring component 302 rotatably connected to the fixing component 301, and a conversion component 303 vertically plugged into the stirring component 302, and the conversion component 303 extends upward into the containing component 101;

[0045] During use, when dust moves to the discharge pipe 105 for discharge, the stirring component 302 will rotate following the squeezing of the collecting component 202. The stirring component 302 that continuously rotates inside the discharge pipe 105 can prevent dust from remaining in the discharge pipe 105 and causing blockage, thereby ensuring that the discharge pipe 105 can perform normal discharge operations.

[0046] Among them, the accommodating component 101 includes a filter bin 101a located between the air inlet component 106 and the air outlet component 107, a filter chamber 101b opened inside the filter bin 101a, and the filter component 102 and the dust removal component 103 are both installed in the filter chamber 101b, and a gear ring 101c that surrounds and fits around the lower position of the inner wall of the filter chamber 101b, and teeth are arranged on the bottom surface of the gear ring 101c.

[0047] Among them, the filter component 102 includes a filter bin 102a located in the filter chamber 101b, multiple groups of filter elements 102b arranged in the filter bin 102a, and a connecting bin 102c opened at the center of the filter bin 102a, and the inner end of the filter element 102b is connected to the connecting bin 102c. Three groups of filter components 102 are arranged inside the accommodating component 101, which are arranged in an upper and lower manner. Each group of filter components 102 is equipped with 16 filter elements 102b, and a dust removal component 103 is arranged on the upper part of each group of filter components 102.

[0048] Furthermore, the dust removal component 103 includes an air storage tank 103a arranged directly above the filter element 102b, and a pipeline is connected between the top of the air storage tank 103a and the air pump 104, a solenoid valve 103b is arranged below the air storage tank 103a, and the solenoid valve 103b extends into the filter element 102b, and a return spring 103c is arranged on the solenoid valve 103b.

[0049] During use, when the filter element 102b is being dusted, the air storage tank 103a is filled with air through the air pump 104, the solenoid valve 103b is opened by pressure and drives the return spring 103c to move backward, causing a short-term pressure loss, so that the solenoid valve 103b is connected with the connecting chamber 102c, and the air in the air storage tank 103a is released instantly, and the filter element 102b is subjected to air pressure impact dust removal, so that the dust attached to the filter element 102b is impacted and falls to the bottom of the filter chamber 101b, and the dust that falls to the bottom can be discharged through the discharge pipe 105 below, ensuring that the filter element 102b is not blocked by dust after working for a long time, and also avoiding maintenance personnel from removing dust from the filter element 102b in a narrow place.

[0050] Among them, the air inlet component 106 includes an air inlet pipe 106a connected to one side of the filter chamber 101a, and the end of the air inlet pipe 106a extends upward, a fan 106b is arranged in the air inlet pipe 106a, and a rain shield 106c is arranged at the end of the air inlet pipe 106a. The top of the air inlet pipe 106a is the air inlet, and the rain shield 106c blocks the air inlet at the top of the air inlet pipe 106a, which can prevent a large amount of rainwater from entering the air inlet pipe 106a, causing the device to be unable to operate normally. The fan 106b is arranged in the air inlet pipe 106a, which may suck external air into the device to assist in the next step of air filtration.

[0051] Furthermore, the air outlet component 107 includes an air outlet pipe 107a connected to the other side of the filter chamber 101a, and an air volume sensor 107b arranged in the air outlet pipe 107a, and the air outlet pipe 107a is connected to control the fan 106b, one end of the air outlet pipe 107a is connected to the inside of the containing component 101, and the other end is connected to the outside, so that the gas filtered by the containing component 101 can be output.

[0052] During use, the air volume sensor 107b is located in the air outlet duct 107a, and the air volume in the air outlet duct 107a is measured by a time-sharing measurement method. The air volume sensor 107b is connected to the fan 106b. If the air volume decreases, the speed of the fan 106b is increased to ensure that sufficient air volume enters the electrical room and the temperature in the electrical room is normal.

[0053] Example 2

[0054] Reference Figure 5~Figure 7 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the dust cleaned from the filter component 102 can be uniformly collected and pushed to the discharge pipe 105, avoiding dust accumulation inside the containing component 101 and accelerating the dust discharge efficiency.

[0055] Compared with Example 1, further, the collecting component 202 includes a connecting plate 202a connected to the top of the driving motor 201 and located at the center of the bottom surface of the filter chamber 101a, three groups of collecting shovels 202b distributed in an annular manner on the outside of the connecting plate 202a, and the ends of the collecting shovels 202b are fixedly connected to the outside of the connecting plate 202a, a baffle 202c vertically arranged on one side of each group of collecting shovels 202b, a collecting groove 202d with a right-angle structure between the collecting shovel 202b and the baffle 202c, and two groups of limiting rings 202e symmetrically arranged on both ends of the baffle 202c, and the transmission component 203 is horizontally connected between the two groups of limiting rings 202e.

[0056] During use, the connecting disk 202a is fixedly connected to the collecting shovel 202b, and the driving motor 201 can drive the collecting shovel 202b to rotate at the bottom of the filter chamber 101b through the connecting disk 202a, and the baffle 202c vertically blocks the side of the collecting shovel 202b. The side of the collecting shovel 202b has a wedge-shaped shovel mouth. When the connecting disk 202a drives the collecting shovel 202b to rotate in a circle, the dust remaining at the bottom of the filter chamber 101b can be shoveled up from the circumferential direction. The shoveled dust will be blocked by the baffle 202c in the vertical direction, so it will remain and accumulate in the collecting groove 202d, and then be driven to move by the rotating collecting shovel 202b, so as to avoid the dust falling through the filter component 102 from accumulating at the bottom of the filter chamber 101b, thereby playing the function of uniformly collecting dust and facilitating the next step of discharge.

[0057] Among them, the transmission component 203 includes a bidirectional screw rod 203a located between two sets of limit rings 202e, and the bidirectional screw rod 203a is provided with a bidirectional thread, limit plates 203b symmetrically arranged at both ends of the bidirectional screw rod 203a, a light rod 203c arranged at the outer end of the bidirectional screw rod 203a, and a limit plate 203b arranged at the outermost end of the light rod 203c, and the limit plate 203b is abutted and meshed with the bottom surface of the gear ring 101c.

[0058] During use, the bidirectional screw rod 203a is limited as a whole on the connecting disk 202a by two sets of limit plates 203b and two sets of limit rings 202e, and can perform axial rotation on the connecting disk 202a without changing its position. The bevel gear 203d at the top of the bidirectional screw rod 203a meshes with the bottom teeth of the gear ring 101c. When the bidirectional screw rod 203a rotates with the collecting component 202, the bevel gear 203d drives the transmission component 203 as a whole to rotate in a circle on the collecting component 202 through meshing with the gear ring 101c.

[0059] Among them, the pushing component 204 includes a pushing block 204a located above the collecting shovel 202b, a connecting sleeve 204b arranged on the side of the pushing block 204a and threadedly connected to the bidirectional screw rod 203a, a pushing plate surface 204c with a rectangular structure arranged on the outside of the pushing block 204a, and the pushing plate surface 204c is slidably connected in the collecting groove 202d, and a shoveling surface 204d with a wedge-shaped structure opened on the other side of the pushing block 204a.

[0060] Furthermore, the connecting sleeve 204b is an annular structure with a notch, and a threaded tooth pattern matching the bidirectional screw rod 203a is provided inside the connecting sleeve 204b. At the same time, the notch below the connecting sleeve 204b is the same width as the baffle 202c. Therefore, the notch below the connecting sleeve 204b is clamped on both sides of the baffle 202c and is limited by the baffle 202c. It can only slide horizontally along the baffle 202c under the drive of the thread of the bidirectional screw rod 203a.

[0061] Furthermore, one side of the pushing component 204 with the pushing plate surface 204c is vertically perpendicular to the collecting groove 202d. Therefore, when the pushing component 204 moves outward along the collecting groove 202d, the dust accumulated in the collecting groove 202d can be pushed by the vertical surface of the pushing plate surface 204c, while the shoveling surface 204d on the other side is a wedge-shaped shovel structure, which can scoop up the remaining dust when moving inward to reset, so as to facilitate the continued pushing of dust when the pushing component 204 moves outward next time, and avoid the dust remaining in the collecting groove 202d being retracted inward when the pushing component 204 is reset.

[0062] During use, the collection component 202 rotates, which will drive the bidirectional screw rod 203a to rotate and move with the bottom midpoint of the filter chamber 101b as the center. During this process, the collection component 202 will scoop up the dust and collect it in the collection groove 202d, and the moving bidirectional screw rod 203a will perform axial rotation on the connecting plate 202a without changing its position through the engagement with the gear ring 101c. The rotating bidirectional screw rod 203a can drive the pushing component 204 to slide horizontally along the collection groove 202d through the threaded connection with the connecting sleeve 204b, and then the dust collected in the collection groove 202d for the first time is pushed again to the position of the inner edge of the filter chamber 101b, that is, the position of the discharge pipe 105, through the push plate surface 204c, thereby accelerating the speed of dust discharge from the discharge pipe 105, thereby uniformly collecting dust and avoiding the problem of untimely dust cleaning affecting the filtering effect of the device.

[0063] The remaining structures are the same as those of Example 1.

[0064] Example 3

[0065] Reference Figure 8~Figure 12 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the dust collecting unit 200 rotates in the discharge pipe 105 to avoid dust accumulation in the discharge pipe 105 and blockage of the discharge pipe 105, thereby ensuring stable dust discharge.

[0066] Compared with Example 2, further, the fixing component 301 includes a fixing ring 301a located in the discharge pipe 105, three groups of fixing rods 301b arranged on the outside of the fixing ring 301a and the outer ends of which are fixedly connected to the inner wall of the discharge pipe 105, multiple groups of connecting rods 301c arranged below the fixing ring 301a, a limit block 301d arranged at the end of the connecting rod 301c, and a rectangular groove 301e opened at the center position of the limit block 301d.

[0067] During use, the fixing component 301 is fixedly installed in the discharge pipe 105 through the fixing rod 301b, and the stirring component 302 is inserted in the fixing ring 301a. Due to its vertical limitation, it can only rotate in the fixing ring 301a with the center of the fixing ring 301a as the origin.

[0068] Among them, the stirring component 302 includes a sleeve 302a inserted on the fixed ring 301a, three groups of stirring frames 302b distributed in an annular manner on the outside of the sleeve 302a, two groups of limit clips 302c arranged on the sleeve 302a and located on the upper and lower sides of the fixed ring 301a respectively, a spring groove 302d opened inside the sleeve 302a, and two groups of spiral grooves 302e spirally wound and opened on the inner wall of the spring groove 302d.

[0069] During use, the stirring frame 302b is fixedly connected to the sleeve 302a and will rotate along with the rotation of the sleeve 302a to achieve stirring and dredging actions. The stirring component 302 is limited on the fixed ring 301a by two sets of limit cards 302c. The spring groove 302d is a spiral structure coiled on the inner wall of the sleeve 302a, and its two ends extend to the upper and lower ends of the sleeve 302a respectively.

[0070] Among them, the conversion component 303 includes an intermediate rod 303a located in the spring groove 302d in the vertical direction, a rectangular rod 303b arranged below the intermediate rod 303a and extending into the rectangular groove 301e, an upper push rod 303c arranged at the top of the intermediate rod 303a, a connecting piece 303d arranged between the intermediate rod 303a and the upper push rod 303c, and two groups of guide teeth 303e arranged on both sides of the connecting piece 303d, and the two groups of guide teeth 303e extend into the two groups of spiral grooves 302e respectively, a conduction block 303f arranged at the top of the upper push rod 303c, and a support spring 303g sleeved on the intermediate rod 303a.

[0071] Furthermore, the middle rod 303a is located in the sleeve 302a, and the rectangular rod 303b is a rectangular structure and passes through the rectangular groove 301e, so it is limited by the rectangular groove 301e and can only perform vertical upward and downward extension movements along it, and the middle rod 303a, the rectangular rod 303b and the conductive block 303f are fixedly connected together, so they are all limited by the rectangular groove 301e.

[0072] Furthermore, the conductive block 303f is a right triangle structure, and the hypotenuse of the triangle is opposite to the rotation direction of the collecting shovel 202b, that is, when the collecting shovel 202b rotates clockwise, the bottom end of the hypotenuse of the conductive block 303f contacts the collecting shovel 202b first.

[0073] Furthermore, the two ends of the support spring 303g respectively abut against the upper inner bottom end of the sleeve 302a and the bottom surface of the connecting piece 303d, and through its elastic support, the connecting piece 303d is always lifted upward, so that the height of the conduction block 303f is always located above the discharge pipe 105, and the guide teeth 303e on both sides of the connecting piece 303d extend into the spiral groove 302e, so that it can slide along its special spiral line.

[0074] During use, when the collection unit 200 collects and pushes the dust to a position close to the discharge pipe 105 through the collection component 202 and the pushing component 204, the moving collection component 202 will squeeze the conduction block 303f, and the squeezed conduction block 303f will diagonally transmit the pressure downward to the middle rod 303a. At this time, the middle rod 303a will move downward and squeeze the support spring 303g through the connecting piece 303d to shrink it. In the process of the middle rod 303a driving the connecting piece 303d to move, the guide teeth 303e on both sides of the connecting piece 303d will move downward along the spiral groove 302e, but due to the threaded structure of the spiral groove 302e The guide tooth 303e will be restricted in its vertical downward movement path. In addition, the conversion component 303 cannot rotate due to the limitation of the rectangular groove 301e, while the stirring component 302 can rotate in a circle on the fixed ring 301a. Therefore, when the fixed component 301 moves downward, the stirring component 302 will convert it into a rotational force through the threaded structure of the spiral groove 302e. At this time, the stirring component 302 will follow the vertical movement of the fixed component 301 and perform a rotational stirring action in the discharge pipe 105, thereby preventing dust from accumulating in the discharge pipe 105 and causing the dust to be unable to be discharged smoothly, thereby ensuring the safe operation of the dust discharge work.

[0075] The remaining structure is the same as that of Example 2.
