Description

Technical Field

[0001] The utility model belongs to the technical field of methanol evaporators, and specifically relates to a methanol evaporator. Background Art

[0002] Urea-formaldehyde pre-contraction liquid is an energy-saving and environment-friendly product. Methanol is prepared from methanol, air and water vapor as main raw materials, and urea and the prepared methanol are used as main raw materials to prepare urea-formaldehyde pre-contraction liquid. The process is continuous, avoiding the cross-regional transportation of the intermediate product methanol. It is safe and efficient. During the processing, an evaporator is used to evaporate the methanol of the urea-formaldehyde pre-contraction liquid processing raw material. The urea-formaldehyde pre-contraction liquid evaporator consists of an evaporation tank body and a heating base. The raw material methanol of the urea-formaldehyde pre-contraction liquid is fed into the evaporation tank body, and the heating base at the bottom of the tank body is heated to cause the raw material methanol of the urea-formaldehyde pre-contraction liquid to produce water vapor evaporation. The evaporated raw material methanol gas of the urea-formaldehyde pre-contraction liquid is mixed into the production line to realize the production of urea-formaldehyde pre-contraction liquid.

[0003] When an existing methanol evaporator is used for the production of urea-formaldehyde pre-shrinkage liquid, methanol is fed into the interior of the evaporator for evaporation. When fed into the evaporator, it is filtered through a glass wool component to filter out impurities in the methanol liquid, thereby improving the purity of the methanol evaporation process. However, the following defects exist: (1) When the glass wool component filters the methanol liquid, its impurities are easily retained on the surface of the glass wool filter component, causing the filter holes to become clogged, making it impossible for the methanol liquid to be fed into the evaporator, thereby affecting the evaporation process. For this reason, we propose a methanol evaporator. Utility Model Content

[0004] The utility model aims to provide a methanol evaporator to solve the problem in the above background technology that after the evaporator filters methanol liquid impurities through a glass wool component, it is easy to get clogged and affect the normal processing of the subsequent evaporator.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a methanol evaporator, comprising an evaporator body, an air outlet pipe is arranged on the top of the evaporator body, a liquid inlet pipe is arranged on the side of the evaporator body, a glass wool filter core plate is inlaid inside the liquid inlet pipe, a mounting frame is fixed inside the liquid inlet pipe, a rotating shaft is inlaid on the mounting frame for rotation, one end of the rotating shaft is connected to a turbine assembly, and the other end of the rotating shaft is connected to a cleaning assembly, and the surface of the cleaning assembly is in contact with the surface of the glass wool filter core plate.

[0006] Preferably, the cleaning assembly consists of a cleaning plate and bristles, and the bristles are installed on the surface of the cleaning plate.

[0007] Preferably, the longitudinal section of the rotating shaft is a circular structure, and the cross section of the rotating shaft is a stem-shaped structure.

[0008] Preferably, a ball groove is provided on the surface of the rotating shaft, and a ball is embedded in the ball groove.

[0009] Preferably, rib plates are connected between the two sides of the mounting frame and the inner wall of the liquid inlet pipe, and the longitudinal section of the rib plates is a triangular structure.

[0010] Preferably, a waste outlet is embedded through the bottom surface of the liquid inlet pipe, and a plug is connected to the inside of the waste outlet through threads.

[0011] Preferably, the longitudinal section of the plug is a convex structure, and the cross sections of the plug and the waste outlet are both circular structures.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) Through the designed mounting frame, rotating shaft, turbine assembly and cleaning assembly, the utility model filters the methanol liquid input into the evaporator through the liquid inlet pipe through the glass wool filter core plate. At the same time, the liquid exerts an impact force on the turbine assembly to rotate the turbine assembly, and the turbine assembly drives the cleaning assembly to rotate. The bristles on the cleaning assembly quickly scrape away the debris remaining on the surface of the glass wool filter core plate to prevent the glass wool filter core plate from being blocked and affecting the methanol liquid from entering the dynamic evaporator for processing. The designed ball bearing plays a lubricating role and reduces the friction resistance between the rotating shaft and the mounting frame that affects the rotation.
