Description

Technical Field

[0001] This utility model relates to the technical field of heat recovery and utilization devices, and in particular to a heat recovery and utilization device for the production of quartz slabs. Background Technology

[0002] The production of quartz slabs consumes a lot of energy, and a large amount of heat energy is lost through production waste gas and equipment heat dissipation. The efficient recovery of a large amount of waste heat generated during the production of quartz slabs allows the waste gas carrying heat to flow into the bend of the tank through the air inlet pipe. The hot waste gas comes into full contact with the water flow outside the pipe to achieve heat exchange. The cold water is heated and then discharged from the outlet pipe as a hot water resource that can be reused. This effectively reduces the energy consumption in the production process.

[0003] Traditional quartz slab production processes typically employ rudimentary support structures. These often rely on vertical supports or unstable temporary installations, and mostly utilize straight-tube designs with limited heat exchange areas. This makes them ill-suited to the complex working conditions of quartz slab production sites, leading to issues such as swaying, tipping over, and failing to meet the energy efficiency requirements of businesses. Therefore, improvements are proposed to address these problems. Utility Model Content

A support ring 2 is provided on the outer wall of the middle section of the recovery tank 1. A connecting support mechanism is provided on the outer wall of the support ring 2. A heat recovery mechanism is located inside the recovery tank 1. A flange connection mechanism is provided at the top of the recovery tank 1, and a filter mechanism is provided at the top of the flange connection mechanism. The recovery tank 1, as the core container for heat recovery, provides a closed and stable space for the operation of the entire device, thus supporting the heat recovery-related components. The connecting support mechanism includes three first connecting seats 3 evenly distributed on the outer wall of the support ring 2 and a supporting inclined rod 4 snapped onto the first connecting seats 3. A second connecting seat 5 is provided at the bottom of the supporting inclined rod 4, and a base plate 6 is provided at the bottom of the second connecting seat 5. A connecting rod is fixedly connected to the middle of the supporting inclined rod 4 for fixation. Through the connection support mechanism, the three first connecting seats 3 are evenly distributed to provide multi-point connections. Combined with the synergistic effect of the supporting inclined rod 4, the second connecting seats 5, the base plate 6, and the connecting rod, a stable triangular support structure is formed, thereby providing a stable heat recovery mechanism for the recovery tank 1. Provides reliable support; the first connecting seat 3 has a first threaded hole, the top of the supporting diagonal rod 4 has a first connecting hole corresponding to the first thread, a first bolt passes through the first thread and the first connecting hole, and the end of the first bolt is threaded with a first nut; the second connecting seat 5 has a second threaded hole, the bottom of the supporting diagonal rod 4 has a second connecting hole corresponding to the second thread, a second bolt passes through the second thread and the second connecting hole, and the end of the second bolt is threaded with a second nut; expansion bolts 8 pass through both sides of the base plate 6, and the top of the expansion bolts 8 is provided with a locking nut 7. Through the setting of these threaded holes, connecting holes and bolts and nuts, a tight connection between the components is achieved. The installation angle and tightness of the supporting diagonal rod 4 can be flexibly adjusted according to actual needs, thereby adapting to the installation requirements of different sites and improving the versatility of the device.

[0021] In this utility model, the heat recovery mechanism includes an inner bend 13 inside the recovery tank 1 and an air inlet pipe 9 at the bottom of the inner bend 13. A water outlet pipe 11 is located in the upper part of the outer wall of the recovery tank 1, and a water inlet pipe 10 is located in the lower part of the outer wall. Through the heat recovery mechanism, the inner bend 13 increases the heat exchange area, the air inlet pipe 9 introduces high-temperature waste gas, and the water inlet pipe 10 and water outlet pipe 11 achieve cold water circulation. These three components work together to efficiently recover waste heat from the quartz slab production process. The flange connection mechanism includes a lower flange 12 at the top of the recovery tank 1 and a corresponding upper flange 15.

Through the setting of the filter mechanism, the air discharged from the recovery tank 1 can be purified.

[0022] Working Principle: When using this utility model, firstly, based on the actual layout of the quartz slab production site, determine the installation position of the recycling tank 1. Place the base plate 6 in the predetermined position, drill holes on both sides of the base plate 6 using tools such as an electric drill, insert expansion bolts 8, and tighten the locking nuts 7 to firmly fix the base plate 6 to the ground. Pick up the support diagonal rod 4, align the first connecting hole at its top with the first threaded hole on the first connecting seat 3, insert the first bolt, and tighten the first nut, but not completely. Similarly, align the second connecting hole at the bottom of the support diagonal rod 4 with the second threaded hole on the second connecting seat 5, insert the second bolt, and tighten the second nut, also not completely. Adjust the angle of the support diagonal rod 4 so that the three support diagonal rods 4 form a stable triangular support structure. Then, tighten the nuts on the first bolt and the second bolt in sequence to ensure that the support diagonal rod 4 is tightly connected with the first connecting seat 3 and the second connecting seat 5, providing reliable support for the recycling tank 1. Place the recycling tank 1 on the support ring 2 and the support diagonal rod 4 using hoisting equipment or manual handling. The supporting structure ensures that the recycling tank 1 is placed stably and does not shake. After the quartz slab production begins, the valve on the air inlet pipe 9 is opened to allow the high-temperature waste gas generated during the production process to enter the inner bend pipe 13 inside the recycling tank 1 through the air inlet pipe 9. At the same time, the valve on the water inlet pipe 10 is opened to allow cold water to flow into the interlayer between the outer wall of the recycling tank 1 and the inner bend pipe 13. After absorbing the heat transferred by the inner bend pipe 13, the temperature of the cold water rises and flows out from the water outlet pipe 11, forming a cold water circulation and realizing heat exchange. During the flow of the high-temperature waste gas in the inner bend pipe 13, the heat is continuously transferred to the surrounding cold water, and the temperature of the waste gas gradually decreases, completing the waste heat recovery process. The recovered heat can be reused according to actual needs, such as being transported to the workshop heating system or used to preheat the raw materials for quartz slab production.
