Description

Technical Field

[0001] The utility model relates to the technical field of industrial evaporation equipment, in particular to a multiple-effect evaporator. Background Art

[0002] In large-scale industrial production, a large amount of water often needs to be evaporated, which requires a lot of energy to heat water and generate steam. In order to reduce the consumption of heating steam, multi-effect evaporation can be used. The heating steam is passed into an evaporator, and the solution is heated and boils. The pressure and temperature of the secondary steam generated are lower than those of the original heating steam. The secondary steam can be used as heating steam and introduced into another evaporator. The introduced secondary steam can serve as a heating heat source. Similarly, the new secondary steam generated by the second evaporator can be used as heating steam for the third evaporator. In this way, each evaporator is called one effect. Connecting multiple evaporators and operating them together constitutes a multi-effect evaporation system, which produces recycling, significantly reduces heat energy consumption, and improves efficiency.

[0003] The existing multi-effect evaporator does not have the function of driving and processing materials. The materials are mostly fixed inside the evaporator, which leads to the problem of insufficient evaporation of the materials in the center, and affects the evaporation efficiency.

[0007] The material driving mechanism includes a raised seat, a cam and a No. 2 motor. The raised seat is fixedly installed on the side of the inner wall of the evaporation chamber, a limiting rod is fixedly installed on the top of the raised seat, a support frame is slidably connected to the outer wall of the limiting rod, an elastic part is fixedly installed on the top of the raised seat, the top of the elastic part is fixedly connected to the bottom of the support frame, the cam is rotatably connected to the left side of the inner wall of the evaporation chamber, the No. 2 motor is fixedly installed on the left side of the evaporation chamber, and the output shaft of the No. 2 motor is fixedly connected to the left end of the cam.

[0008] Preferably, a positioning frame is fixedly installed on the top of the support frame, a plug-in strip is movably inserted into the inner cavity of the positioning frame, a locking bolt is threadedly connected to the side of the positioning frame, and the threaded end of the locking bolt is movably connected to the side of the plug-in strip.

[0009] Preferably, an evaporation screen frame is fixedly mounted on the top of the plug-in strip, and a connecting rod is welded to the side of the evaporation screen frame.

[0010] Preferably, the steam heating mechanism includes hollow strips, and the number of the hollow strips is set to two. The two hollow strips are respectively fixedly installed on both sides of the inner wall of the evaporation chamber. A heat exchange copper tube is fixedly connected between the two hollow strips, and the sides of the two hollow strips away from each other are fixedly connected with a connecting elbow and a condensate overflow pipe.

[0011] Preferably, the steam heating mechanism also includes a support leg, a rotating shaft and a No. 1 motor. The support leg is fixedly mounted on the back of the inner wall of the evaporation chamber. A cylinder is fixedly mounted on the outer wall inside the support leg.

[0014] This utility model provides a multiple-effect evaporator to address the problem of poor material evaporation efficiency in existing multiple-effect evaporators. The design of the second motor drives a cam to rotate. When the cam rotates in an inverted state, it pushes the support frame downward. The initial elastic force of the elastic member drives the support frame upward, thereby causing the material in the inner cavity of the evaporation net frame to vibrate up and down, ensuring sufficient contact between the material and the hot air in the inner cavity of the evaporation chamber, thereby improving the evaporation efficiency and efficiency of the water in the material.

[0025] The following is a detailed description of the working principle of this multi-effect evaporator.

[0026] like Figure 1 - Figure 5As shown, the material to be evaporated is added to the inner cavity of the evaporation screen frame 344, the plug-in strip 343 is plugged into the inner cavity of the positioning frame 341, and then the locking bolt 342 is manually rotated to complete the positioning of the plug-in strip 343 and the evaporation screen frame 344 as a whole, and the external steam output pipe is connected to the end of one of the connecting elbows 23, so that the steam flows through the inner cavity of the heat exchange copper tube 22, and the No. 1 motor 254 is controlled to work, driving the blade 253 to rotate in the inner cavity of the cylinder 251, so that the air in the evaporation chamber 1 is circulated internally, and then the No. 2 motor 36 is controlled to work to drive the cam 35 to rotate, which can cause the material in the inner cavity of the evaporation screen frame 344 to shake up and down, thereby realizing the function of efficient evaporation.
