Description

Technical Field

[0001] This utility model relates to the technical field of waste heat collection devices, and in particular to a waste heat collection device for metal heat treatment. Background Technology

[0002] Metal heat treatment typically involves multiple stages, including heating, holding, and cooling, and is primarily used to improve the mechanical properties, hardness, and corrosion resistance of metallic materials. Besides exhaust gases and fumes, wastewater is also a significant source of energy and resource consumption during metal heat treatment. Wastewater generation is mainly related to processes such as metal cooling, cleaning, and surface treatment.

[0003] Wastewater typically carries a large amount of heat and pollutants, which, if not properly treated or recycled, can pollute the environment and increase production costs for businesses. Therefore, those skilled in the art have provided a waste heat collection device for metal heat treatment to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a waste heat collection device for metal heat treatment. The waste heat in the wastewater can be effectively treated through the set outlet mechanism, thereby achieving the benefits of environmental protection. Furthermore, the set filtration mechanism can perform solid-liquid separation treatment on the treated wastewater, thereby achieving better recyclability.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A waste heat collection device for metal heat treatment includes a collection box, an outlet mechanism is provided inside the collection box, and a filter mechanism is fixedly connected to the lower part of one outer wall of the collection box.

[0007] The discharge mechanism includes an inlet pipe and an outlet pipe. The inlet pipe is fixedly connected to the upper part of one side inner wall of the collection box, and the outlet pipe is fixedly connected to the lower part of the other side inner wall of the collection box. A spiral cooling pipe is fixedly connected between the inlet pipe and the outlet pipe. The upper end of the inlet pipe passes through the collection box and is fixedly connected to an injection cone. The injection cone is fixedly connected to the outer wall of one side of the collection box.

[0008] The above technical solution introduces the waste liquid into the injection cone, and then flows into the spiral cooling pipe through the feed pipe. Its heat can transfer heat to the wall of the spiral cooling pipe, and assist in heating the cooling water in the collection box through heat transfer, thus achieving the benefit of waste heat collection and treatment.

[0009] Furthermore, the filtration mechanism includes a filter cover, which is fixedly connected to the discharge pipe. A guide frame is movably sleeved inside the filter cover, and a filter screen is fixedly sleeved inside the guide frame.

[0010] Through the above technical solution, wastewater can flow to the filter cover through the discharge pipe. Under the action of the filter screen, impurities in the wastewater can be effectively separated, thus providing convenience for subsequent classification and treatment.

[0011] Furthermore, connecting rods are fixedly connected to the upper end face of the guide frame at both the front and rear positions. A limiting plate is fixedly connected to the upper end of the two connecting rods. A fixing groove is opened on both sides of the limiting plate at both the front and rear positions. A return spring is fixedly connected to the inner wall of one side of the fixing groove. A movable seat is fixedly connected to the other end of the return spring. A locking rod is fixedly connected to the side of the movable seat away from the movable seat. A locking groove is opened on both sides of the inner wall of the filter cover at both the front and rear positions. The locking rod is locked into the locking groove.

[0012] The above technical solution allows the limiting plate to be removed by moving the movable seat and compressing the return spring, thus cleaning the filter screen. The return spring pops out without resistance, and the movable seat moves and drives the locking rod to lock into the locking groove, thereby fixing the filter screen.

[0013] Furthermore, each of the multiple movable seats is fixedly connected to a toggle lever on its upper end face, and the upper end face of the limiting plate is provided with a toggle groove near the four corners, and the toggle lever is movably disposed in the toggle groove.

[0014] The above technical solution allows for the adjustment and movement of the movable seat by setting a lever.

[0015] Furthermore, a handle is fixedly connected to the center of the upper end face of the limiting plate, and the handle is U-shaped;

[0016] With the above technical solution, the restriction plate can be moved freely using the handle provided.

[0017] Furthermore, a water inlet pipe is fixedly connected to the center of the upper end face of the collection box, and a No. 1 shut-off valve is fixedly installed on the outer wall of the water inlet pipe;

[0018] The above technical solution, through the water inlet pipe and the No. 1 shut-off valve, can achieve the purpose of water injection, and at the same time, the opening and closing function of the water inlet pipe can be adjusted.

[0019] Furthermore, a water outlet pipe is fixedly connected to the center of the lower end face of the collection box, and a second shut-off valve is fixedly installed on the outer wall of the water outlet pipe;

[0020] The above technical solution, through the installed water outlet pipe and No. 2 shut-off valve, can achieve the purpose of drainage, and at the same time, the opening and closing function of the water outlet pipe can be adjusted.

[0021] Furthermore, support columns are fixedly connected to the lower end face of the collection box near the four corners, and anti-slip pads are fixedly connected to the lower end of each support column.

[0022] The above technical solution, with its support columns and anti-slip pads, can provide stable support for the collection box.

[0023] This utility model has the following beneficial effects:

[0024] 1. The present invention proposes a waste heat collection device for metal heat treatment. In use, cold water is injected into the collection tank through the inlet pipe. At this time, the waste liquid is introduced into the injection cone and then flows into the spiral cooling pipe through the feed pipe. The heat can transfer heat to the wall of the spiral cooling pipe and assist in heating the cooling water in the collection tank through heat transfer, thus achieving the benefit of waste heat collection. After the waste liquid is cooled, it is discharged through the discharge pipe. Then, the heated water can be discharged by opening the second shut-off valve. New cooling water can be injected again for reheating treatment, which has a better waste heat collection effect.

[0025] 2. This utility model proposes a waste heat collection device for metal heat treatment. Wastewater flows through the discharge pipe to the filter cover. Under the action of the filter screen, impurities in the wastewater can be effectively separated, thus providing convenience for subsequent classification and treatment. When it is necessary to clean or replace the filter screen, the lever can be pulled to move the moving seat and drive the return spring to compress. Pulling the handle can remove the limiting plate, allowing the filter screen to be processed. When replacing the filter screen, simply pull the lever again to lock the limiting plate into the filter cover. Releasing the lever allows the return spring to pop out without resistance, the moving seat moves and drives the locking rod to move so that it locks into the locking groove, thereby achieving the purpose of stable use.
