Self-cleaning and automatic deslagging filter

Abstract

The invention discloses a self-cleaning and automatic deslagging filter used for deslagging cane juice in a cane sugar factory. The self-cleaning and automatic deslagging filter comprises an air inlet pipe, a sweeping screen sprayer, a piston slag pushing device, a cane juice inlet pipe, a cane juice distributor, a wedge-shaped screen, a cover plate, a solid waste slag discharging hole, a shell and a cane juice outlet pipe. The self-cleaning and automatic deslagging filter is characterized in that the rectangular wedge-shaped screen is arranged in the shell, the cane juice distributor is arranged at one end of the wedge-shaped screen, and is connected with the cane juice inlet pipe, the piston slag pushing device is arranged on the surface of the wedge-shaped screen, solid waste slag is discharged from the solid waste slag discharging hole in the other end of the wedge-shaped screen, the sweeping screen sprayer is arranged on the bottom surface of the wedge-shaped screen and is connected with the air inlet pipe, the cover plate is arranged above the shell to prevent the solid waste slag from being sprayed, and the cane juice outlet pipe is arranged below the shell, and is connected with a cane juice tank below the cane juice outlet pipe. The self-cleaning and automatic deslagging filter has the advantages of good filtering effect, low energy consumption, small noise, simple structure, reliable work and the like; self-cleaning and automatic deslagging are easily realized.

Description

technical field [0001] The invention relates to a self-cleaning and automatic slag-discharging filter used for deslag-removing cane juice in a sugarcane sugar factory. Background technique [0002] The primary heating of the original process of the sugarcane sugar factory is to extract the juice vapor to heat the cane juice. The shell and tube heater is used. Due to the high solid content of the cane juice and the high scaling components, the flow rate of the cane juice in the shell and tube heater is low. The fouling of the tubes is serious, resulting in low heat transfer efficiency, and it needs to be cleaned every day, which has become a major problem for sugar refining enterprises. Research on how to improve the heat transfer efficiency of the cane juice heater and solve the problem of easy blockage and fouling of the heater is an important topic for energy saving and consumption reduction in sugarcane sugar factories. [0003] Relevant public documents have reported me...
