Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, specifically a dustproof power distribution cabinet for mineral processing and screening machinery. Background Technology

[0002] A distribution cabinet is a device used for power distribution and control. It is an enclosed, metal device containing various electrical components such as circuit breakers, switches, contactors, fuses, and transformers. These components work together to distribute power to different loads or devices. The main function of a distribution cabinet is to control and monitor the power supply while protecting the circuit from faults and abnormal conditions. Distribution cabinets are equipped with heat dissipation structures to dissipate the heat generated by the electrical components inside the cabinet.

[0003] Mineral processing and screening operations include crushing and screening, grinding and classification. Their main purpose is to separate valuable minerals from gangue minerals, and to separate valuable minerals from each other, achieving individual separation and preparing for further sorting operations. The mineral processing and screening environment involves a significant amount of dust. Traditional mineral processing and screening machinery uses a power distribution cabinet that delivers external air into the cabinet for heat dissipation. Although filters are installed to filter airborne dust, some fine dust particles still enter the cabinet during actual operation. These fine dust particles can affect the electrical components inside the cabinet, impacting their lifespan and posing safety hazards, thus compromising the safety of mineral processing and screening operations. Therefore, this paper proposes a dustproof power distribution cabinet for mineral processing and screening machinery. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6In this embodiment of the utility model, the dustproof power distribution cabinet for mineral processing and screening machinery includes a cabinet assembly 1 consisting of a power distribution cabinet body 101 and a front cabinet door 102. The front cabinet door 102 is rotatably connected to the opening of the power distribution cabinet body 101 via a hinge. Heat dissipation chambers 103 are integrally formed on both sides of the power distribution cabinet body 101. Heat dissipation components 2 are provided on the inner side of the heat dissipation chambers 103 and the inner side of the power distribution cabinet body 101. The heat dissipation components 2 are used to dissipate heat inside the power distribution cabinet body 101.

[0029] Heat dissipation component 2 includes a heat transfer unit and a ventilation unit;

[0030] The heat transfer unit is used to enable the internal cavity of the two heat dissipation chambers 103 to be connected. The ventilation unit is used to transport external air through the heat transfer unit. At the same time, the heat transfer unit is used to enable the heat transfer operation between the high temperature air inside the main body of the power distribution cabinet 101 and the normal temperature air passing through the heat transfer unit.

[0031] The heat transfer unit includes heat dissipation pipes 205 and heat dissipation fins 206;

[0032] Ventilation openings 104 are provided on the inner wall side of the heat dissipation chamber 103. The heat dissipation pipe 205 is fixed to the inner side of the main body 101 of the power distribution cabinet, and the two ends of the heat dissipation pipe 205 are respectively connected to the ventilation openings 104 on the two heat dissipation chambers 103. The heat dissipation fins 206 are symmetrically fixed to both ends of the inner wall of the heat dissipation pipe 205 and extend out to the inner cavity of the main body 101 of the power distribution cabinet.

[0033] When the flowing ambient air passes through the inner cavity of the heat dissipation pipe 205, it exchanges heat with the high-temperature air inside the main body 101 of the power distribution cabinet through the heat dissipation pipe 205 and the heat dissipation fins 206.

[0034] The ventilation unit includes a side cabinet door 201, an air inlet hood 202, a filter screen 203, an air intake fan 204, and a mesh cabinet door 207;

[0035] The side cabinet door 201 and the mesh cabinet door 207 are respectively connected to the openings of the two heat dissipation chambers 103 by hinges.

[0036] The air intake shroud 202 is fixed to the bottom of one side of the side cabinet door 201 and extends through the side cabinet door 201 into the heat dissipation chamber 103. The filter screen 203 is inserted and installed inside the air intake shroud 202. The air intake fan 204 is fixedly installed inside the air intake shroud 202 and is distributed between the filter screen 203 and the heat dissipation chamber 103.

[0037] The intake fan 204 is used to draw ambient air into a heat dissipation chamber 103. The ambient air then flows through the vent 104 and the heat dissipation pipe 205 to another heat dissipation chamber 103, thereby achieving air circulation.

[0038] In this embodiment: When this power distribution cabinet is in use, by starting the intake fan 204, the intake fan 204 can draw ambient air into a heat dissipation chamber 103. During this process, the filter screen 203 can filter the air.

[0039] The ambient temperature air entering a heat dissipation chamber 103 flows through the vent 104 and heat dissipation pipe 205 to another heat dissipation chamber 103, and finally exits through the mesh on the mesh cabinet door 207. During this process, the high temperature air inside the main body 101 of the power distribution cabinet transfers heat to the ambient temperature air inside the heat dissipation pipe 205 through the heat dissipation pipe 205 and heat dissipation fins 206, thereby achieving heat dissipation operation inside the main body 101 of the power distribution cabinet.

[0040] Through the cooperation of the above components, heat dissipation is achieved inside the main body 101 of the power distribution cabinet, while preventing external air from entering the main body 101 of the power distribution cabinet. This effectively avoids the entry of fine dust into the main body 101 of the power distribution cabinet, achieving a highly efficient dustproof effect and effectively improving the safety of the power distribution cabinet in use.

[0041] Please refer to this carefully. Figures 1-4 Multiple sets of heat dissipation pipes 205 are evenly arranged in the vertical direction. Each set of heat dissipation pipes 205 includes multiple heat dissipation pipes 205 distributed in the horizontal longitudinal direction. The number and position of the ventilation openings 104 correspond one-to-one with the number and position of the heat dissipation pipes 205.

[0042] A single heat dissipation pipe 205 is provided with multiple vertically distributed heat dissipation fins 206, and the heat dissipation fins 206 on two adjacent heat dissipation pipes 205 in each group of heat dissipation pipes 205 are vertically staggered.

[0043] In this embodiment: the heat exchange area is further improved by the structure of multiple sets of heat dissipation pipes 205 and multiple heat dissipation fins 206 of a single heat dissipation pipe 205, and heat dissipation operation can be performed on different height areas inside the main body of the power distribution cabinet 101.

[0044] The structure of the heat dissipation fins 206 on two adjacent heat dissipation pipes 205 being vertically staggered ensures that the overall internal space of the main body of the power distribution cabinet 101 remains connected.

[0045] Please refer to this carefully. Figure 2 , Figure 5 , Figure 6 A rectangular sealing frame 105 is fixed to the inner side of the main body 101 of the power distribution cabinet near the opening and the inner side of the heat dissipation chamber 103 near the opening. The frames of the front cabinet door 102, the side cabinet door 201, and the mesh cabinet door 207 are respectively attached to the three rectangular sealing frames 105.

[0046] In this embodiment, it should be noted that a sealing strip is adhered to the side of the rectangular sealing frame 105 near the front cabinet door 102 and the side cabinet door 201. The sealing strips on the rectangular sealing frame 105 of the front cabinet door 102 and the side cabinet door 201 are tightly fitted, which not only ensures the sealing of the inside of the power distribution cabinet body 101, but also ensures that the heat dissipation chamber 103 corresponding to the side cabinet door 201 maintains a good sealing effect, thereby ensuring the stability of the air flow trajectory.

[0047] Furthermore, the side cabinet door 201 and the mesh cabinet door 207 can be rotated and opened to clean the heat dissipation pipe 405, for example, by using a high-pressure air gun to blow away the tiny dust inside the heat dissipation pipe 405.

[0048] It should also be noted that the front cabinet door 102, the side cabinet door 201, and the mesh cabinet door 207 are closed and locked using traditional cabinet lock devices. Cabinet lock devices are widely used in the field of power distribution cabinets, so they will not be described in detail here.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
