Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, and more specifically to an evaporator that is resistant to cold and low-temperature environments. Background Technology

[0002] With the acceleration of industrialization, the amount of wastewater generated in the production process of various industries is constantly increasing. This wastewater often contains a variety of harmful substances, and direct discharge will cause serious pollution to the environment. Therefore, it is necessary to use effective wastewater treatment equipment to treat this wastewater. In recent years, governments around the world have attached increasing importance to environmental protection and have introduced a series of strict environmental protection regulations and policies. These regulations and policies require enterprises to take effective environmental protection measures in the production process, including wastewater treatment. As a highly efficient wastewater treatment device, wastewater evaporators have been widely used.

[0003] In cold environments, existing evaporators face a series of challenges, one of the most significant being a marked decrease in evaporation rate. This decrease not only directly leads to a significant reduction in evaporation efficiency but also indirectly affects the performance and stability of the entire system. When the ambient temperature is too low, the evaporation process of water becomes slow, which means that in order to achieve the same throughput, it is necessary to take longer or increase additional energy input to maintain operation. This not only increases operating costs but may also cause unnecessary wear and tear on the equipment.

[0004] Furthermore, when wastewater is used as raw material for evaporation treatment, as water is gradually removed, minerals dissolved in the water (such as calcium and magnesium) will continuously concentrate and eventually deposit to form scale. This scale adheres to the inner surface of the evaporator, greatly hindering the heat transfer process and further reducing heat exchange efficiency. Over time, this accumulation may lead to pipe blockage or even damage to key components, thereby shortening the equipment's service life and increasing maintenance difficulty and costs.

[0005] Therefore, in order to solve the above problems, this application provides an evaporator that is resistant to cold and low-temperature environments. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an evaporator that is resistant to cold and low temperature environments, so as to solve the problems existing in the background art.

[0007] This utility model provides the following technical solution: an evaporator resistant to cold and low temperature environments, including an evaporation main assembly and a valve assembly installed on the evaporation main assembly, a vacuum assembly and a condensation assembly installed on the side wall of the evaporation main assembly, a stirring assembly provided inside the evaporation main assembly, and a sludge suction and circulation assembly provided at the connection between the stirring assembly and the valve assembly;

[0008] Preferably, the evaporator assembly includes a combustion chamber and an evaporator, with the evaporator snapped onto the combustion chamber.

[0009] Preferably, the valve assembly includes a water inlet pipe, a water control valve, a connecting plastic part, a preheating pipe, and a heat-conducting plate. The water control valve is installed on the water inlet pipe, and the connecting plastic part is fixedly sleeved on the water inlet pipe. The connecting plastic part is fixedly sleeved on one end of the preheating pipe near the water inlet pipe. The preheating pipe surrounds the combustion chamber cavity, and the heat-conducting plate is fixedly installed in the combustion chamber cavity, with the preheating pipe positioned between the combustion chamber and the heat-conducting plate. At this time, rotating the water control valve allows the wastewater to be treated to enter the preheating pipe, and the wastewater inside is preheated through the preheating pipe's surrounding pipe inside the combustion chamber and the heat-conducting plate.

[0010] Preferably, the vacuum assembly includes a suction pipe, a vacuum pump, and an outlet pipe. One end of the suction pipe is fixedly installed on the side wall of the evaporator and connected to the inner cavity of the evaporator. The other end of the suction pipe is fixedly connected to the inlet of the vacuum pump. The vacuum pump is fixedly installed on the combustion chamber. The outlet of the vacuum pump is fixedly connected to the outlet pipe. At this time, the vacuum pump evacuates the inside of the evaporator through the suction pipe, which lowers the boiling point of the wastewater and makes it easier to generate water vapor.

[0011] Preferably, the condensation assembly includes an air inlet pipe, a condenser, and a water outlet pipe. One end of the air inlet pipe is fixedly installed on the side wall of the evaporator and connected to its inner cavity, while the other end is fixedly sleeved to the air inlet of the condenser. The water outlet pipe is fixedly sleeved to the water outlet of the condenser. At this time, the water vapor generated during the heating process of the evaporator enters the condenser through the air inlet pipe, and the condensed water vapor flows out through the water outlet pipe.

[0012] Preferably, the stirring assembly includes a rotary motor, a drive gear, a driven gear, a suction pipe, a connecting pipe, a leak-proof rubber ring, a water transport pipe, a stirring bend, and a small suction pipe. The rotary motor is fixedly connected to the inner wall of the evaporator. The drive shaft of the rotary motor is fixedly sleeved with the drive gear, which meshes with the driven gear. The driven gear is fixedly sleeved with the suction pipe. The stirring bend is fixedly sleeved below the suction pipe. Small suction pipes are evenly distributed on the bottom spiral tube of the stirring bend. The connecting pipe is movably snapped onto the top of the suction pipe. The water transport pipe is fixedly sleeved with the connecting pipe and communicates with the inner tube of the connecting pipe. The leak-proof rubber ring is placed at the joint between the connecting pipe and the evaporator to ensure the sealing of the evaporator. At this time, the drive shaft of the rotary motor drives the drive gear, which, through meshing, drives the driven gear and the suction pipe to rotate, and also drives the stirring bend.

[0013] Preferably, the sludge suction and circulation assembly includes a power motor, a rotating blade, a connecting sleeve, a filter, and a filter tube. The power motor is fixedly clamped to the inner wall of the connecting sleeve, the power motor drive shaft is fixedly sleeved to the rotating blade, a water transport pipe is fixedly sleeved above the connecting sleeve and communicates with its inner cavity, the upper water inlet of the filter is fixedly sleeved to the connecting sleeve and communicates with it, the side water outlet of the filter is fixedly sleeved to the filter tube and communicates with it, and a preheating pipe is fixedly sleeved at the end of the filter tube away from the filter. At this time, the power motor drive shaft drives the rotating blade to rotate and generate negative pressure. The sediment at the bottom of the evaporator enters the stirring bend through the suction pipe, then enters the filter after passing through the suction pipe, connecting pipe, and water transport pipe. After passing through the filter to remove sediment, it enters the evaporator again through the filter tube and preheating pipe.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] During equipment operation, wastewater enters the preheating pipe and is preheated through the surrounding pipes and heat-conducting fins inside the combustion chamber. Simultaneously, a vacuum pump creates a vacuum, lowering the boiling point of the wastewater and making it easier to generate water vapor. This significantly increases the evaporation rate of the equipment in low-temperature environments. At the same time, the rotating motor drives the stirring bend through transmission, and the power motor drives the rotating blades to generate negative pressure, causing the sediment at the bottom of the evaporator to enter the filter. After passing through the filter to remove sediment, the wastewater passes through the filter pipe and the preheating pipe before entering the evaporator again, thereby reducing sedimentation and improving heat transfer efficiency.
