Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a control cabinet for the operation and maintenance of wastewater treatment. Background Technology

[0002] A wastewater treatment control cabinet is an electrical control system used to control wastewater treatment operations, effectively improving treatment efficiency. During wastewater treatment, control cabinets are frequently used to manage the process, simplifying operations and significantly enhancing flexibility. However, during prolonged operation, wastewater treatment control cabinets often lack robust protective structures, preventing the timely dissipation of internal heat, which can easily affect their performance.

[0003] Existing technology, such as the wastewater treatment distribution cabinet disclosed in patent application CN202120352094.4, includes a cabinet body. The cabinet body houses electrical control components, an aerator, and a heat dissipation coil assembly. The heat dissipation coil assembly is located on the outer edge of the aerator. The cabinet body has a first fixing hole and a second fixing hole. The inlet end of the heat dissipation coil assembly extends out of the first fixing hole and is used to connect to the outlet end of a wastewater inlet pipe. The outlet end of the heat dissipation coil assembly extends out of the second fixing hole and is used to connect to the inlet end of a wastewater outlet pipe. The inlet end of the wastewater outlet pipe is used to connect to a wastewater treatment tank, which contains a culture medium. This technical solution integrates the electrical control components and the aerator into a single unit, making it easy to operate, particularly suitable for buried wastewater treatment equipment. It also improves the heat dissipation effect of the distribution cabinet and is energy-saving and environmentally friendly.

[0004] Although the above technical solution uses a heat exchange coil to dissipate heat inside the control cabinet, it does not filter the wastewater inside the heat exchange coil. If large amounts of water or debris enter the heat exchange coil and cause blockage, the water flow rate inside the heat exchange coil will decrease, resulting in a reduction in heat dissipation. Utility Model Content

The cooling inlet pipe and cooling outlet pipe of the cooling coil assembly pass sequentially through the side wall of the dustproof chamber and the side wall of the control cabinet body, respectively, and are connected to a sewage inlet pipe and a sewage outlet pipe located outside. The cooling inlet pipe is connected to the sewage inlet pipe via a T-junction. The remaining opening of the T-junction is connected to the sewage outlet pipe via a straight discharge pipe. A filter screen is provided between the T-junction and the cooling inlet pipe.

[0007] The wastewater treatment operation and maintenance control cabinet according to the present utility model embodiment has at least the following beneficial effects: by setting a three-way pipe with a filter screen to connect with the wastewater inlet pipe, the filtered wastewater enters the heat dissipation inlet pipe, while other wastewater carrying water and garbage enters directly into the wastewater outlet pipe through a direct discharge pipe, avoiding the clogging of the heat dissipation coil assembly and the resulting decrease in heat dissipation effect. The heat dissipation fan combined with the heat dissipation coil assembly further improves the overall heat dissipation effect of the control cabinet, and the existence of the dustproof chamber can effectively reduce the possibility of dust entering the dustproof chamber and accumulating dust on the electrical control components.

[0008] According to some embodiments of this utility model, a flow control valve is connected to the straight discharge pipe.

An air inlet is provided on the side of the lower cabinet, and an exhaust outlet is provided on the side of the upper cabinet. A ventilation grille is provided at the bottom of the dustproof chamber, and an air outlet is provided at the top of the dustproof chamber.

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0026] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0027] refer to Figure 1 as well as Figure 2As shown, the wastewater treatment operation and maintenance control cabinet according to an embodiment of the present utility model includes a control cabinet body. Electrical control components (not shown in the figure), a cooling fan 300, and a cooling coil assembly 400 are installed inside the control cabinet body. A dustproof chamber 200 is connected inside the control cabinet body. The cooling fan 300 is connected above the dustproof chamber 200. The electrical control components and the cooling coil assembly 400 are both connected inside the dustproof chamber 200. The cooling water inlet pipe 410 and the cooling water outlet pipe 420 of the cooling coil assembly 400 pass sequentially through the side wall of the dustproof chamber 200 and the side wall of the control cabinet body, respectively, and are connected to the external wastewater inlet pipe 430 and wastewater outlet pipe. The cooling water inlet pipe 410 and the wastewater inlet pipe 430 are connected through a T-connector 450. The remaining opening of the T-connector 450 is connected to the wastewater outlet pipe through a straight discharge pipe 460. A filter screen 470 is provided between the T-connector 450 and the cooling water inlet pipe 410.

[0028] In actual use, a three-way pipe 450 with a filter screen 470 is connected to the sewage inlet pipe 430. Only the filtered sewage enters the heat dissipation inlet pipe 410, while other sewage carrying water and garbage enters the sewage outlet pipe directly through the direct discharge pipe 460. This avoids the condenser coil assembly 400 from being blocked, which would reduce the heat dissipation effect. The cooling fan 300, together with the condenser coil assembly 400, further improves the overall heat dissipation effect of the control cabinet. The presence of the dustproof chamber 200 can effectively reduce the possibility of dust entering the dustproof chamber 200 and accumulating on the electrical control components.

[0029] In some specific embodiments of this utility model, it may also have the following additional technical features: a flow control valve (not shown in the figure) is connected to the direct discharge pipe 460. Furthermore, a one-way valve (not shown in the figure) is connected to the heat dissipation inlet pipe 410. Through the above design, when the sewage volume is small, the flow rate of the direct discharge pipe 460 is reduced by decreasing the opening of the flow control valve, ensuring the amount of sewage entering the heat dissipation coil assembly 400 and thus guaranteeing the heat dissipation effect. When the sewage volume is large, the flow rate of the direct discharge pipe 460 is increased by increasing the opening of the flow control valve, ensuring that the sewage can be discharged in time and enter the subsequent treatment process. The presence of the one-way valve prevents sewage from flowing back into the heat dissipation coil assembly 400.

[0030] It should be noted that the electrical control components, cooling fan 300, flow control valve and check valve are all technical solutions well known to those skilled in the art. They can be obtained by consulting reference books and purchasing them on the market according to actual needs and parameters. Their specific structure and principle will not be described in detail here.

[0031] In some specific embodiments of this utility model, it may also have the following additional technical features: the diameter of the straight discharge pipe 460 is larger than the diameter of the heat dissipation water inlet pipe 410.

[0032] In some specific embodiments of this utility model, it may also have the following additional technical features: the control cabinet body includes an upper cabinet 110 and a lower cabinet 120, an inner platform 121 extends horizontally from the top of the lower cabinet 120 toward the center of the lower cabinet 120, the upper cabinet 110 is detachably covered and connected to the inner platform 121, the dustproof chamber 200 is detachably and sealed to the inner platform 121, and the dustproof chamber 200 is separated from the lower cabinet 120. An air intake chamber is formed by enclosure, and an exhaust chamber is formed between the dustproof chamber 200 and the upper cabinet 110. An air intake 122 is provided on the side of the lower cabinet 120, and an exhaust vent 111 is provided on the side of the upper cabinet 110. A ventilation grille 210 is provided at the bottom of the dustproof chamber 200, and an air outlet 220 is provided at the top of the dustproof chamber 200. The dustproof chamber 200 is connected to both the air intake chamber and the exhaust chamber. A cooling fan 300 is connected above the air outlet 220 of the exhaust chamber.

[0033] By using the upper cabinet 110, lower cabinet 120, and mounting cabinets with openings at the top and bottom, along with the fan, the internal airflow of the control cabinet is limited to flow from bottom to top. On the one hand, the fan limits the airflow to be discharged from the exhaust port 111, thereby minimizing the entry of dust in the air into the exhaust chamber through the exhaust port 111. On the other hand, the dust that enters the lower cabinet 120 will settle in the air intake chamber under the action of gravity, reducing the impact of dust on the electrical components inside the mounting cabinet, while also ensuring the overall heat dissipation effect.

[0034] In some specific embodiments of this utility model, it may also have the following additional technical features: the heat dissipation inlet pipe 410 and the heat dissipation outlet pipe 420 respectively pass through the side wall of the upper cabinet 110, and both the heat dissipation inlet pipe 410 and the heat dissipation outlet pipe 420 are located above the exhaust port 111. Through the above design, the presence of the heat dissipation inlet pipe 410 and the heat dissipation outlet pipe 420 in the exhaust chamber can further prevent dust that may enter the exhaust chamber from the exhaust port 111 and try to rise, reducing the possibility of dust entering the dustproof chamber 200 through the exhaust port 220.

[0035] In some specific embodiments of this utility model, it may also have the following additional technical features: an outer platform 230 is horizontally connected to the outer periphery of the dustproof chamber 200, the outer surface of the dustproof chamber 200 abuts against the inner wall of the inner platform 121, and the outer platform 230 overlaps the inner platform 121. Through the above ingenious design, the installation cabinet can be easily disassembled and separated from the upper cabinet 110 and the lower cabinet 120, facilitating disassembly, maintenance, and subsequent periodic dust removal.

[0036] In some specific embodiments of this utility model, it may also have the following additional technical features: a support bracket 123 is connected to the inner wall of the lower cabinet 120, and the top of the support bracket 123 is fixedly connected to the bottom of the inner platform 121. This design can enhance the structural strength of the inner platform 121, thereby improving its service life.

[0037] In some specific embodiments of this utility model, it may also have the following additional technical features: the air inlet 122 is located below the support bracket 123, and the exhaust outlet 111 is located near the inner platform 121. This design extends the airflow path within the air inlet and exhaust chambers as much as possible. In the air inlet chamber, a higher air inlet 122 allows for a longer airflow path, thus reducing the gas velocity. Conversely, a lower exhaust outlet 111 prevents dust particles in the airflow from overcoming the force of the airflow due to gravity, thus preventing them from rising to the top of the mounting cabinet and entering the interior of the mounting cabinet through the exhaust outlet 220.

[0038] refer to Figure 3 As shown, in some specific embodiments of this utility model, it may also have the following additional technical features: the bottom of the dustproof chamber 200 has a first annular dustproof cover 240, the first annular dustproof cover 240 extends toward the bottom of the lower cabinet 120 and has a gap with the bottom of the lower cabinet 120, and the ventilation grille 210 is located inside the first annular dustproof cover 240. Through the above ingenious design, after the gas enters from the air inlet 122, its downward path in the air inlet chamber is extended. According to the Coanda effect, the airflow in the air inlet chamber will naturally adhere to the first annular dustproof cover 240 and flow smoothly into the installation cabinet. During this process, the dust carried by the airflow, due to the slowing of the gas flow rate and the effect of gravity, settles to the bottom of the lower cabinet 120, thereby achieving the dustproof effect of the installation cabinet. It is worth mentioning that, due to the presence of static electricity, the more dust settles, the stronger its adsorption force on the dust in the airflow, promoting more dust to settle and further improving the dustproof effect. At the same time, the more dust there is, the stronger its hygroscopicity, which can reduce the amount of water vapor entering the dustproof chamber 200 and reduce the humidity in the dustproof chamber 200.

[0039] In some specific embodiments of this utility model, it may also have the following additional technical features: the top of the dustproof chamber 200 has a second annular dustproof cover 250, the second annular dustproof cover 250 extends toward the top of the upper cabinet 110 and has a gap between it and the top of the upper cabinet 110, and the air outlet 220 is located inside the second annular dustproof cover 250 and connected to the top center of the dustproof chamber 200.

[0040] Through the above ingenious design, the presence of the second annular dust cover 250 increases the climbing height of the airflow entering the exhaust chamber from the exhaust port 111, making it more difficult for dust in the airflow to climb and settle on the outer platform 230. Due to the active exhaust of the fan, the gas velocity in the gas flow channel increases, thereby forming a greater impact force, which can further hinder the climbing of dust in the airflow entering the exhaust chamber from the exhaust port 111.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
