Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a high-efficiency wastewater cooler with filtration function. Background Technology

[0002] Wastewater includes domestic sewage, industrial wastewater, and other non-useful substances such as rainwater runoff into drainage pipes and ditches. Wastewater treatment is the process of purifying wastewater through physical, chemical, and biological methods to reduce pollution and make it meet discharge standards or reuse requirements. Wastewater coolers are heat exchange devices specifically designed to lower the temperature of industrial wastewater. Their core function is to cool the high-temperature wastewater generated during the production process to the temperature required for subsequent treatment or discharge standards. They are widely used in chemical, power, metallurgical, and pharmaceutical industries and are one of the key pretreatment devices in industrial wastewater treatment systems.

[0003] To address this, Chinese patent application CN211260752U discloses a new wastewater cooler for an MTO (Mechanical Toll Collection) unit, comprising a reactor, a quench tower, a separator, a heat exchanger, a wastewater tank, and a slurry tank. The top of the reactor is connected to the quench tower, and the bottom of the quench tower is connected to the separator. The bottom of the separator is connected to the slurry tank. An exhaust pipe is installed on the left side of the top of the separator, and two heat exchangers are arranged on the right side of the separator, connected to each other by equally spaced heat-conducting fins. The tops of the heat exchangers are connected to the top of the separator via steam pipes. A stud is installed at the center of the top of each heat exchanger, and multi-media filter plates are evenly spaced on the stud. This invention not only enables online cleaning of the heat exchangers, ensuring the continuity of MTO unit operation, but also improves the internal cleaning efficiency of the wastewater cooler.

[0004] The aforementioned MTO unit's newly added wastewater cooler enables online cleaning of the heat exchanger, thereby ensuring the continuity of MTO unit operation and improving the internal cleaning efficiency of the wastewater cooler. However, the cooler's outer casing is difficult to disassemble and assemble, and internal malfunctions are difficult to repair, making unit maintenance relatively difficult. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency wastewater cooler with filtration function to solve the problem that existing high-efficiency wastewater coolers are difficult to disassemble and assemble.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency wastewater cooler with filtration function, including support legs;

[0007] The top of the support leg is fitted with a housing, and the top and bottom of the housing are fitted with connecting pipes. Connecting structures are fitted on both sides of the housing.

[0008] The connecting structure includes a first flange installed on both sides of the outer shell, and a cover is installed on both sides of the connecting structure, with an inlet installed on one side of the top of the cover.

[0009] An outlet is installed on one side of the bottom end of the cover. A heat exchange tube is embedded inside the outer shell. A spacer tube is installed inside the outer shell, and a pull rod is installed inside the spacer tube.

[0010] In use, wastewater is first loaded into the casing through the inlet. The heat exchange tubes exchange heat and cool the wastewater, while the casing also absorbs heat. The mounting plate and heat sink are made of brass, which has high thermal conductivity. The mounting plate and heat sink absorb heat through the heat sink. The large surface area of ​​the heat sink allows for rapid heat dissipation, and the through holes increase the surface area of ​​the heat sink. The heat dissipation of the heat sink improves the heat dissipation effect of the wastewater. The cooled wastewater can be discharged through the outlet.

[0011] Furthermore, a heat dissipation structure is installed on the outer side of the housing, and the heat dissipation structure includes a mounting plate installed on the outer side of the housing, and heat sinks are installed on the outer side of the mounting plate. The heat dissipation structure can improve the heat dissipation effect.

[0012] Furthermore, the heat sink has through holes on its outer side, which are arranged at equal intervals on the outer side of the heat sink, thereby increasing the surface area of ​​the heat sink.

[0013] Furthermore, a second flange is provided on one side of the first flange, a nut is installed on one side of the first flange, and a threaded rod is installed on one side of the nut. A nut is installed on the outer side of one side of the threaded rod. The connection structure allows the device to be disassembled and assembled.

[0014] Furthermore, the outer side wall of the threaded rod is uniformly provided with external threads, and the inner side wall of the nut is uniformly provided with internal threads that cooperate with the external threads. The threaded rod and the nut are threadedly connected, and the nut can be screwed onto the threaded rod.

[0015] Furthermore, the nuts are arranged at equal intervals on one side of the second flange, and the nuts are distributed in a ring, so that the nuts can fix the flange.

[0016] Furthermore, the cover and the outer shell form a snap-fit ​​structure, with the cover symmetrically distributed about the central axis of the outer shell, and the snap-fit ​​structure facilitates disassembly.

[0017] Furthermore, a filter structure is installed inside the cover. The filter structure includes a mounting block installed inside the cover, and a connecting block is installed on the inner side of the mounting block. The filter structure can filter wastewater.

[0018] Furthermore, a locking block is provided on the outer side of the connecting block, and a locking groove is provided inside the mounting block. The connecting block and the mounting block form a locking structure, which facilitates disassembly.

[0019] Furthermore, a filter element is provided inside the connecting block, and the outer diameter of the filter element is smaller than the inner diameter of the connecting block, so that wastewater can be filtered through the filter element.

[0020] The advantages of this utility model are: during use, the outer shell and cover can be connected and installed through the connecting structure; the internal wastewater can be filtered through the filtration structure; and the outer shell can be cooled and dissipated more effectively through the heat dissipation structure.

[0021] The first flange on one side of the outer shell and the second flange on the side of the cover are fitted together. Then, the threaded rod on the nut side can pass through the holes of the first and second flanges. The threaded rod and the nut form a threaded connection. The nut can be tightened to connect the first and second flanges together. In this way, the cover and the outer shell can be connected together. When it is necessary to maintain the inside of the outer shell, the nut can be unscrewed, the cover can be disassembled, and the inside of the outer shell can be maintained and repaired. This achieves the purpose of easy disassembly and assembly of the high-efficiency wastewater cooler.

[0022] An installation block is installed inside the cover. The installation block and the connecting block form a snap-fit ​​structure. The connecting block can be snapped into the installation block to install the filter element inside the cover. When wastewater enters the shell through the inlet, it can be filtered by the filter element to prevent impurities from entering the shell. When the filter element needs to be disassembled, it can be replaced by removing the cover. This achieves the purpose of a high-efficiency wastewater cooler that facilitates wastewater filtration.

When wastewater enters the housing 1 through the inlet 6, it can be filtered by the filter element 803 to prevent impurities from entering the housing 1. When the filter element 803 needs to be disassembled, it can be replaced by removing the cover 7.

[0040] The cover 7 and the outer shell 1 form a locking structure. The cover 7 is symmetrically distributed about the central axis of the outer shell 1. An inlet 6 is installed on one side of the top of the cover 7.
