Abstract

This utility model provides a wastewater heat recovery device for bonding wire production wastewater, comprising: a wastewater filtration assembly, which includes a filter box, a flushing pipe, a drain pipe, a filter screen, a sealing seat, and a corrosion-resistant sealing ball. Compared with the prior art, this utility model has the following advantages: by adding a wastewater filtration assembly, a wastewater heat recovery box, a top cover assembly, and a wastewater heat recovery pipe, before heat exchange in wastewater heat recovery, the wastewater is introduced into the filter box and filtered by the filter screen to remove impurities. After the filter screen removes a large amount of impurities, it is guided by a high-pressure water jet through the flushing pipe. The high-pressure water jet impacts the corrosion-resistant sealing ball, causing it to detach from the sealing connection with the sealing seat, so that the impurities are discharged through the drain pipe. The filtered wastewater is introduced into the body of the heat recovery box and undergoes heat exchange through the wastewater heat recovery pipe. Heat loss is reduced by the top cover assembly, thereby assisting in the use of wastewater heat recovery. By adding the top cover assembly and the wastewater heat recovery pipe, it is easier to disassemble and assemble the wastewater heat recovery pipe.

Description

Technical Field

[0001] This utility model belongs to the field of bonding wire production technology, and specifically relates to a waste heat recovery device for bonding wire production wastewater. Background Technology

[0002] Bonding wires are core interconnect materials in semiconductor packaging, primarily used to achieve electrical connections between chips (dies) and lead frames or substrates. Their production process requires strict control over purity, diameter accuracy, mechanical properties, and surface quality to meet high-reliability bonding requirements. High-temperature wastewater is generated during bonding wire production. Traditionally, this wastewater is directly discharged and then undergoes a series of treatments. Current technologies often utilize the wastewater for heat recovery, such as preheating for heat recovery. However, during wastewater recovery, impurities in the wastewater, especially those flowing through heat exchangers, can cause blockages in the pipes or heat exchangers, affecting normal wastewater heat recovery.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content

A waste heat recovery box is installed on the right side of the wastewater filtration assembly. A top cover assembly is installed on top of the waste heat recovery box. The waste heat recovery box includes a recovery box body and a flow interrupter. The flow interrupter is fixedly connected to the inside of the recovery box body.

[0007] In a preferred embodiment, the flushing pipe is independently controlled by a valve, a sealing spring is fixedly connected below the corrosion-resistant sealing ball, and a support base is fixedly connected below the sealing spring. The corrosion-resistant sealing ball is sealed to the sealing base without the impact of water flow. In daily wastewater filtration, the sealing spring drives the corrosion-resistant sealing ball to the upper end and seals it with the sealing base, thereby realizing the one-way flow of wastewater.

[0008] In a preferred embodiment, water guide pipes are fixedly connected to both the left and right sides of the recovery tank body, and several sets of flow-breaking plates are arranged at intervals in the front-to-back direction.

[0012] In a preferred embodiment, two sets of clamping seats are symmetrically installed on the side of the positioning seat near the perforation. The clamping seats and clamping grooves are movably fitted together. The clamping screws are threadedly connected to the clamping seats. An outer ring groove is opened on the outer side of the end connecting pipe. The clamping seats and the outer ring grooves are fitted together.

After the filter screen removes a large amount of impurities, it is guided to a high-pressure water jet through the flushing pipe. The high-pressure water jet impacts the corrosion-resistant sealing ball, causing it to detach from the sealing connection with the sealing seat, allowing the impurities to be discharged through the drain pipe.

Detailed Implementation

[0023] 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.

[0024] Please see Figures 1-6 As the first embodiment of this utility model: A waste heat recovery device for bonding wire production wastewater includes: a wastewater filtration assembly 100, which includes a filter box 101, a flushing pipe 104, a drain pipe 106, a filter screen 107, a sealing seat 108, and a corrosion-resistant sealing ball 109. A flushing pipe 104 for timed flushing is fixedly connected to the top of the filter box 101, a drain pipe 106 is fixedly connected to the bottom of the filter box 101, a filter screen 107 is installed inside the filter box 101, a sealing seat 108 is fixedly connected to the lower end of the inner side of the filter box 101, and a corrosion-resistant sealing ball 109 is provided below the sealing seat 108. A waste heat recovery box 200 is installed on the right side of the wastewater filtration assembly 100. A top cover assembly 300 is installed on the top of the waste heat recovery box 200. The waste heat recovery box 200 includes a recovery box body 201 and a flow interrupter 203. The flow interrupter 203 is fixedly connected to the inside of the recovery box body 201. A waste heat recovery pipe 400 is also installed inside the recovery box body 201.

[0025] A water inlet pipe 102 is fixedly connected to the left side of the filter box 101, and a water inlet conduit 103 is installed on the left side of the water inlet pipe 102. A water outlet pipe 105 is fixedly connected to the right side of the filter box 101.

[0026] The flushing pipe 104 is independently controlled by a valve. A sealing spring 110 is fixedly connected below the corrosion-resistant sealing ball 109, and a support base is fixedly connected below the sealing spring 110. The corrosion-resistant sealing ball 109 is sealed to the sealing base 108 without the impact of water flow. In daily wastewater filtration, the sealing spring 110 drives the corrosion-resistant sealing ball 109 to the upper end to seal with the sealing base 108, realizing the one-way flow of wastewater.

[0027] Water guide pipes 202 are fixedly connected to both sides of the recovery box body 201. Several sets of flow cut-off plates 203 are arranged at intervals in the front-back direction. The waste heat recovery pipe 400 includes heat exchange pipe 401 and end connecting pipe 402.

[0028] The heat exchange tube 401 is configured with several sets of bent structures and each end is fixedly connected to a set of end connecting pipes 402. Both sets of end connecting pipes 402 are interconnected with the external heat exchange conduit. The heat exchange tubes 401 are distributed at the water passages of several sets of flow-breaking plates 203.

[0029] The top cover assembly 300 includes a top cover body 301. A sealing heat insulation plate 302 is fixedly connected to the bottom of the top cover body 301. A set of perforations 303 are vertically penetrating the upper surface of the top cover body 301 on the left rear and right front. Wastewater passes through the recycling tank body 201 and the sealing heat insulation plate 302 to reduce heat loss. It also passes through several sets of flow-breaking plates 203 to reduce the flow rate of wastewater and increase the flow path, thereby improving the contact with heat exchange and improving the heat exchange effect.

[0030] Specifically, during use, wastewater is guided through the inlet pipe 103 and connected to the inlet pipe 102, leading to the filter box 101. The wastewater passes through the filter screen 107 to remove impurities before being discharged through the outlet pipe 105. During routine wastewater filtration, the sealing spring 110 drives the corrosion-resistant sealing ball 109 to its upper end, sealing it against the sealing seat 108, achieving unidirectional wastewater flow. After the filter screen 107 removes a significant amount of impurities, the flushing pipe 104 delivers a high-pressure water jet that impacts the impurities inside the filter screen 107 (flushing out impurities). The valve controls the on / off state of the pipe (and the control method uses existing mature technology, which will not be elaborated here), and the corrosion-resistant sealing ball 109 moves down and detaches from the sealing connection with the sealing seat 108 under the impact of the high-pressure water column, so that impurities are discharged through the drain pipe 106. Secondly, the wastewater passes through the heat insulation plate 302 in the recovery tank body 201 to reduce heat loss, and passes through several sets of flow-breaking plates 203 to reduce the flow rate of the wastewater and increase the flow path, thereby improving the contact with the heat exchanger and improving the heat exchange effect, thus assisting in the recovery and use of waste heat.

[0031] Please see Figure 1 and Figures 5-6 As a second embodiment of this utility model: A set of positioning seats 304 are fixedly connected to the left rear and right front of the upper surface of the top cover body 301. A clamping groove 305 is provided on the right side of the positioning seat 304. A clamping screw 306 is rotatably installed inside the clamping groove 305 to drive the two sets of clamping seats 307 to move in opposite directions at the same time.

[0032] Two sets of clamping seats 307 are symmetrically installed on the side of the positioning seat 304 near the through hole 303. The clamping seats 307 and the clamping slide 305 are movably engaged with each other. The clamping screw 306 is threadedly connected to the clamping seats 307. An outer ring groove 403 is opened on the outer side of the end connecting pipe 402. The clamping seats 307 and the outer ring groove 403 are engaged with each other. The end connecting pipe 402 in the waste heat recovery pipe 400 passes through the through hole 303 and is clamped and fixed by the clamping seats 307 and the outer ring groove 403.

[0033] Based on the first embodiment described above, the end connecting pipe 402 in the waste heat recovery pipe 400 passes through the through hole 303. When the operator rotates the clamping screw 306 in cooperation with the clamping seat 307, it drives the two sets of clamping seats 307 to move closer together, so that the two sets of clamping seats 307 are engaged with the outer ring groove 403 to complete the clamping and fixing, thereby facilitating the disassembly and assembly of the waste heat recovery pipe 400.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
