Description

Technical Field

[0001] This utility model relates to the field of industrial waste acid treatment technology, specifically to an evaporation device for industrial waste acid treatment. Background Technology

[0002] Waste acid, also known as waste sulfuric acid, is treated by effectively separating dissolved substances from dilute acid solutions. After purification, waste acid can be recycled. Waste sulfuric acid treatment mainly includes processes such as waste sulfuric acid concentration, high-temperature pyrolysis, chemical oxidation, extraction, crystallization, fertilizer production, and neutralization. Different companies typically adopt different treatment processes based on the amount, concentration, impurity composition and content, and intended use of the treated sulfuric acid. In industrial production, waste acid may be generated during processes such as nitration, esterification, sulfonation, alkylation, catalysis, and gas drying of organic matter, or during processes such as titanium dioxide production, steel pickling, and gas drying. Currently, most waste acid treatment methods employ acid-base neutralization. The reaction of waste acid with alkali solution produces a salt solution, which requires evaporation and crystallization.

[0003] Existing evaporation devices for treating industrial waste acid evaporate the waste acid by heating it. However, when heating and evaporating industrial waste acid, the waste acid is relatively still and is not agitated, resulting in uneven heating and incomplete evaporation.

[0004] Therefore, an evaporation device for treating industrial waste acid is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an evaporation device for treating industrial waste acid, which can solve the problem that when industrial waste acid is heated and evaporated, it is relatively still and not shaken or stirred, resulting in uneven heating and insufficient evaporation of the industrial waste acid.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an evaporation device for treating industrial waste acid, comprising a base, a holding box installed on the top of the base, a pushing mechanism provided at the bottom of the holding box and the base, a support frame fixed at the top center of the base, a heating evaporation mechanism installed at the top of the support frame, and a driving moving mechanism installed at the top of the heating evaporation mechanism.

[0007] The driving mechanism includes a gear and a rack. The gear is rotatably mounted on the inner top of the support frame, and the rack is meshed and driven on both sides of the gear. The rack is slidably mounted on the inner side of the support frame.

[0008] The heating and evaporation mechanism includes a first heat-conducting pipe and a heat-conducting plate. The heat-conducting plate is installed at the bottom end of the rack and located at the top of the container. The first heat-conducting pipe is evenly connected to the bottom end of the heat-conducting plate, and its bottom end is inserted into the interior of the container.

[0009] Preferably, the pushing mechanism includes a push-pull plate, which is slidably mounted on the top of the base, with an electric push rod installed at one end. A side plate is fixed to one end of the base, and the electric push rod is horizontally mounted on the side of the side plate. The push-pull plate has a rectangular plate structure and is horizontally arranged.

[0010] Preferably, a guide strip is fixed in the middle of the bottom end of the push-pull plate, and a guide groove is opened in the middle of the top end of the base. The guide strip is slidably inserted into the guide groove. The cross-section of the guide groove and the guide strip are both T-shaped structures and are both horizontally arranged.

[0011] Preferably, the support frame is a U-shaped structure and is vertically arranged, the container is a rectangular box structure and is fixed to the top of the push-pull plate and slidably installed inside the support frame, and a discharge pipe is connected to one bottom end of the container.

[0012] Preferably, the first heat-conducting pipe is vertically arranged and has a gap between it and the bottom of the container. The heat-conducting plate is a hollow rectangular plate structure and is horizontally arranged. Connecting plates are fixed at both ends of its top end. The connecting plates are vertically arranged. The rack is installed between the two connecting plates. Bolts are used to connect the outer side of the connecting plate to the outer end of the rack.

[0013] Preferably, the rack has a sliding groove on its outer side, a support plate is fixed to the top of the inner side of the support frame, the support plate is slidably inserted into the sliding groove, the support plate is horizontally arranged, a motor is installed in the middle of the top of the support frame, the gear is rotatably installed on the top of the motor, and the rack is horizontally arranged.

[0014] Preferably, hot air blowers are installed at both ends of the top of the support frame, and a second heat-conducting pipe is connected to the side of the hot air blower. The bottom end of the second heat-conducting pipe is connected to one end of the heat-conducting plate, and the second heat-conducting pipe adopts a telescopic flexible hose structure.

[0015] Compared with the prior art, this utility model provides an evaporation device for treating industrial waste acid, which has the following beneficial effects:

[0016] 1. The container is fixed to the top of the sliding plate and is movably installed on the base. After the industrial waste acid is heated and evaporated inside the container, there will be crystal residue inside. The sliding plate and the container are moved to one end of the base by the electric push rod, exposing a large space at one end of the container, which makes it easier to clean the crystal residue inside the bottom of the container.

[0017] 2. A rack is slidably installed on the top of the support frame via a support plate, and a heat-conducting plate and a first heat-conducting pipe are installed at the bottom of the rack. Thus, when industrial waste acid is poured into the container, the motor drives the gear to rotate and meshes to drive the rack on both sides to move back and forth in a cyclical manner, thereby driving the first heat-conducting pipe to heat the industrial waste acid in the container at different positions, so as to facilitate the full heating of the industrial waste acid in the container.

[0018] 3. Moreover, as the rack drives the heat-conducting plate and the first heat-conducting pipe to move back and forth, the first heat-conducting pipe can also stir and mix the industrial waste acid inside the container. Furthermore, the heat emitted from the bottom of the first heat-conducting pipe can also blow and agitate the industrial waste acid, thereby improving the evaporation efficiency of the industrial waste acid.
