Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, specifically to a material anti-accumulation structure for evaporators. Background Technology

[0002] Currently, most methods for treating industrial and domestic wastewater involve evaporation and concentration. After evaporation and concentration, distilled water that meets discharge or reuse standards can be extracted from the waste liquid. The remaining concentrated residue is then discharged to a wastewater treatment plant or outsourced for further treatment. Existing evaporation equipment typically discharges the concentrated residue through a discharge port in the evaporator. During the evaporation process, as the concentration of the liquid in the evaporator gradually increases, the concentrated residue is continuously squeezed against the end cap at the discharge port. Due to the gap between the stirring components inside the evaporator and the discharge port, material accumulates and clumps on the end cap. This is especially true for materials with high viscosity, making discharge of the concentrated residue difficult, easily leading to incomplete discharge, blockage of the discharge port, and consequently, unstable system pressure. Furthermore, the accumulation of material on the end cap can wear down the mechanical seal of the evaporator, damaging it and causing leaks. This can even affect the normal operation of the evaporation and concentration equipment, increasing maintenance costs. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a material anti-accumulation structure for evaporators, which can solve the existing problems of material accumulation and blockage, and incomplete material discharge, while reducing maintenance costs.

[0004] This utility model adopts the following technical solution: a material anti-accumulation structure for an evaporator, including a tank body, an end cap installed at the discharge end of the tank body, a stirring shaft arranged along the axial direction inside the tank body, a spiral stirring blade connected to the stirring shaft, a discharge port provided on the end cap, a discharge baffle provided on the inner side of the end cap at the discharge port, the discharge baffle being arc-shaped along the stirring direction, and the length of the discharge baffle being 1 / 4 to 1 / 2 of the circumference of the discharge port.

[0005] Furthermore, the discharge baffle is located at the upper right corner of the discharge port, and the distance between the discharge baffle and the discharge port gradually decreases until it is connected to the discharge port;

[0006] Furthermore, a plurality of radially extending stirring rods are connected to the stirring shaft, the stirring rods being arranged alternately with each other at intervals, and the spiral stirring blades are all connected to the stirring rods;

[0007] Furthermore, a slag discharge assembly is provided on the outside of the end cap located at the discharge port. The slag discharge assembly includes a main slag discharge tank and a slag discharge cylinder. The main slag discharge tank has a three-way structure. The slag discharge cylinder is installed at one of the outlets of the main slag discharge tank through a cover plate. The piston rod of the slag discharge cylinder passes through the cover plate and extends into the main slag discharge tank. A plug for sealing the discharge port is connected to the piston rod.

[0008] Furthermore, the main tank for slag discharge is composed of a first discharge pipe, a second discharge pipe, and a third discharge pipe. The first discharge pipe is connected to the discharge port, the second discharge pipe is connected to the end of the first discharge pipe, and the third discharge pipe is inclinedly connected to the side end of the first discharge pipe. The slag discharge cylinder is installed at the outlet of the second discharge pipe through the cover plate.

[0009] Furthermore, the main tank for discharging residue is connected to an air inlet pipe, which is connected to a steam pipeline.

[0010] The beneficial effects of this utility model are that the material inside the evaporator is discharged towards the discharge port as it is stirred by the stirring shaft and the spiral stirring blades. By providing a discharge baffle on the inner side of the end cover at the discharge port, a tangential rotational force is applied to the material at the discharge port. Through the material's own gravity, the material can be discharged from the discharge port gradually, thereby preventing the material from accumulating and clumping at the discharge port of the end cover. This ensures the normal operation of the evaporation and concentration equipment, reduces maintenance costs, and has good economic value. Attached Figure Description

[0019] like Figures 1 to 8 As shown, the present invention discloses a material anti-accumulation structure for an evaporator, comprising a tank body 1, an end cap 2 installed at the discharge end of the tank body 1, a stirring shaft 3 arranged along the axial direction inside the tank body 1, a spiral stirring blade 4 connected to the stirring shaft 3, a discharge port 5 provided on the end cap 2, and a discharge baffle 6 provided on the inner side of the end cap 2 located at the discharge port 5, the discharge baffle 6 being arc-shaped along the stirring direction, and the length of the discharge baffle 6 being 1 / 4 to 1 / 2 of the circumference of the discharge port 5.

[0020] The discharge baffle 6 is located at the upper right corner of the discharge port 5. The distance between the discharge baffle 6 and the discharge port 5 gradually decreases until it is connected to the discharge port 5.

[0021] Several radially extending stirring rods 7 are connected to the stirring shaft 3. The stirring rods 7 are arranged alternately and at intervals. The spiral stirring blades 4 are all connected to the stirring rods 7.

[0022] A slag discharge assembly is provided on the outside of the end cap 2 located at the discharge port 5. The slag discharge assembly includes a main slag discharge tank and a slag discharge cylinder 8. The main slag discharge tank has a three-way structure. The slag discharge cylinder 8 is installed at one of the outlets of the main slag discharge tank through a cover plate 9. The piston rod of the slag discharge cylinder 8 extends into the main slag discharge tank after passing through the cover plate 9. A plug 13 for sealing the discharge port 5 is connected to the piston rod. Specifically, the main slag discharge tank is composed of a first discharge pipe 10, a second discharge pipe 11, and a third discharge pipe 12. The first discharge pipe 10 is connected to the discharge port 5. The second discharge pipe 11 is connected to the end of the first discharge pipe 10. The third discharge pipe 12 is inclinedly connected to the side end of the first discharge pipe 10. The slag discharge cylinder 8 is installed at the outlet of the second discharge pipe 11 through a cover plate 9.

[0023] The main tank for discharging residue is connected to an air inlet pipe 14, which is connected to a steam pipe (not shown in the figure). During discharge, high-temperature steam is introduced into the air inlet pipe 14 through the steam pipe, which can further blow away the residue material in the main tank for discharging residue, thereby achieving the purpose of cleaning and preventing blockage.

[0024] The working principle of this utility model is as follows: after evaporation is completed and the material discharge mode is entered, when the negative pressure inside the evaporator tank 1 drops to a set threshold, the slag discharge cylinder 8 opens, that is, the plug 13 is moved from the discharge port 5 until it returns to the opening of the second discharge pipe 11. The stirring shaft 3 and its spiral stirring blades 4 operate (specifically, the stirring shaft 3 is connected to a corresponding drive device, and the drive device can adopt an existing drive structure, which will not be described in detail in this utility model embodiment). The material is discharged to the discharge port 5. Through the set discharge baffle 6, on the one hand, when the stirring rod 7 spreads the material evenly on the surface of the end cover 2, the material is discharged. The baffle 6 provides a guiding force to the material, directing it towards the discharge port 5. Simultaneously, it applies a tangential rotational force to the material above, which, combined with the material's own weight, causes it to fall, preventing accumulation and clumping on the end cap 2. Finally, the material is discharged from the third discharge pipe 12. This solves the existing problems of material accumulation and blockage, and incomplete discharge, ensuring stable system pressure. Furthermore, the slag discharge cylinder 8 and its connected plug 13 prevent material leakage, avoiding the situation where the existing discharge port 5 cannot be properly closed. This ensures the normal operation of the evaporation and concentration equipment, reduces maintenance costs, and minimizes processing steps.
