[0002] In the pre-treatment process of silicon steel sheets, a large amount of water circulation and cooling process is involved. In this process, the treatment water will carry a lot of heat. In order to effectively utilize the waste heat of the treatment water and reduce energy consumption and environmental pollution, a recovery device will be used to recover the heat;

[0003] At present, when the waste heat recovery device recovers waste heat, the treatment water is sent into the recovery device, and then the pipe with heat transfer medium is brought into contact with the treatment water to absorb the heat of the treatment water so that the heat transfer medium can use the waste heat for other purposes;

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0025] In order to solve the technical problems in the background technology, a device for utilizing waste heat from pre-treatment water of silicon steel plates is provided as follows:

[0026] Combination Figure 1-Figure 5 As shown, the utility model provides a silicon steel plate pre-treatment water waste heat utilization device, comprising a recovery box 1, the recovery box 1 comprises an outer box 11, a recovery mechanism 2 is arranged inside the outer box 11, a recovery component 3 for recovering waste heat is arranged inside the recovery mechanism 2, an inner box 12 is arranged inside the outer box 11, a heat preservation cavity is formed between the outer box 11 and the inner box 12, a water inlet pipe 13 is arranged at the top of the outer box 11 and the top of the inner box 12, and the setting of the heat preservation cavity is convenient for maintaining the waste heat of the treatment water, so that the recovery mechanism 2 can recover the waste heat;

[0027] The recovery mechanism 2 includes a recovery box 21, a liquid inlet pipe 22, a liquid discharge pipe 23, a partition plate 24 and a spoiler rod 25. The recovery box 21 is fixedly arranged inside the inner box 12. A liquid discharge pipe 23 is arranged on one side of the top of the recovery box 21, and a liquid inlet pipe 22 is arranged on the other side of the top of the recovery box 21. The end of the liquid discharge pipe 23 is located outside the outer box 11. A partition plate 24 is arranged inside the recovery box 21. A plurality of partition plates 24 are arranged inside the recovery box 21. The plurality of partition plates 24 are distributed at intervals inside the recovery box 21. A recovery channel is formed between the plurality of partition plates 24. The recovery channel is distributed in an S shape. The spoiler rod 25 is located inside the recovery channel. The spoiler rod 25 is fixedly connected to the partition plate 24. The S-shaped recovery channel is convenient for the treatment water to contact the recovery component 3 along the path of the recovery channel to recover heat.

[0028] In this embodiment, a plurality of spoiler rods 25 are provided inside the recovery channel, and the plurality of spoiler rods 25 are distributed in an array. The spoiler rods 25 distributed in the array can disperse the treatment water when the treatment water flows in the recovery channel, thereby facilitating the treatment water to uniformly contact and conduct heat with the recovery component 3.

[0029] In this embodiment, the recovery component 3 includes a second liquid inlet pipe 31, a liquid separation box 1 32, a heat conduction pipe 33, a liquid separation box 2 34, a liquid collecting box 35 and a second liquid discharge pipe 36. The second liquid inlet pipe 31 and the second liquid discharge pipe 36 are both arranged at the top of the recovery box 21, and the top of the second liquid inlet pipe 31 and the top of the second liquid discharge pipe 36 are both located outside the inner box 12. The bottom of the second liquid inlet pipe 31 is provided with a liquid separation box 1 32, and the bottom of the second liquid discharge pipe 36 is provided with a liquid collecting box 35. The bottom of the liquid separation box 1 32 and the liquid collecting box 35 are provided. A heat conducting pipe 33 is provided below the liquid box 35. A plurality of heat conducting pipes 33 are provided below the liquid separation box 1 32 and the liquid collection box 35. The plurality of heat conducting pipes 33 are connected in sequence through the liquid separation box 2 34. The distribution of the heat conducting pipes 33 and the liquid separation box 2 34 corresponds to the recovery channel. The heat conducting pipes 33 and the liquid separation box 2 34 provided in the recovery component 3 can transport the heat conducting medium to flow in the reverse direction along the flow direction of the recovery channel, thereby facilitating the heat conducting medium to fully absorb heat and conduct heat to the treated water.

[0030] In this embodiment, heat-conducting fins 37 are provided on the outside of the heat-conducting pipe 33. There are multiple groups of heat-conducting fins 37 on the outside of the heat-conducting pipe 33. The heat-conducting pipe 33 is evenly distributed inside the recovery channel. The setting of the heat-conducting fins 37 can assist the heat-conducting pipe 33 in transferring waste heat to the flowing heat-conducting medium.

[0031] The implementation principle of the first embodiment is as follows: when the silicon steel plate pre-treatment water needs to recover the waste heat, the treatment water is sent into the inner box 12 through the water inlet pipe 13, and then the treatment water with waste heat will enter the recovery box 21 through the liquid inlet pipe 1 22 and flow along the recovery channel, and finally be discharged from the liquid discharge pipe 1 23. During this process, the heat-conducting medium flows in the liquid inlet pipe 2 31, the liquid separation box 1 32, the heat-conducting pipe 33, the liquid separation box 2 34, the liquid collecting box 35 and the liquid discharge pipe 2 36 in sequence. The flowing heat-conducting medium has an opposite flow direction to the treatment water. The heat-conducting medium will continuously absorb the waste heat of the treatment water when flowing, so as to facilitate the subsequent waste heat utilization. At the same time, the treatment water will be continuously dispersed by the spoiler rod 25 when flowing, so that the waste heat inside the treatment water can be fully transferred to the heat-conducting medium, which is beneficial to improving the waste heat recovery efficiency of the device. Example 2

[0032] like Figure 1-Figure 4 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0033] In order to make the treated water carry some dirty impurities during the waste heat recovery process, these dirty impurities are easily accumulated inside the recovery pipe, affecting the waste heat recovery. In order to reduce the impact of the internal dirty impurities on the recovery mechanism 2 and the recovery component 3, this embodiment provides the following design:

[0034] A sewage collecting assembly 4 is provided at the bottom of the outer box 11. The sewage collecting assembly 4 includes a flow blocking rod 41 and a sewage valve 44. The flow blocking rod 41 is provided at the bottom side of the recovery box 21. The flow blocking rod 41 is distributed in an array. The setting of the flow blocking rod 41 can disperse the treatment water flowing from bottom to top, so that impurities in the treatment water can be settled.

[0035] As an improvement of the above-mentioned scheme, the sewage collecting component 4 also includes a sewage guide plate 42, a sewage guide plate 42 and a sewage pipe 43. The sewage guide plate 42 is arranged at the inner bottom of the outer box 11. The top surface of the sewage guide plate 42 is inclined. The inclined sewage guide plate 42 can guide dirty impurities to flow toward the sewage pipe 43. A sewage pipe 43 is provided on the bottom side of the outer box 11. A sewage valve 44 is provided on the outside of the sewage pipe 43. The sewage pipe 43 can discharge the dirt that has been settled for a long time in the treated water from the device.

[0036] The implementation principle of the second embodiment is: when the treated water enters the inner box 12, the treated water will be blocked by the recovery box 21, and the blocked treated water will flow upward after sinking to the bottom. At this time, the flowing treated water will hit the flow blocking rods 41 distributed in the array, so that the treated water will be more dispersed in the inner box 12 to settle the dirty impurities. Then, the dirty impurities will fall during the flow process, and the treated water after the dirty impurities are settled will continue to flow into the recovery mechanism 2 for waste heat recovery.
