Description

Technical Field

[0001] This utility model relates to the field of chemical and bioenergy production equipment technology, specifically an automatic slag discharge structure for a crude glycoside filter. Background Technology

[0002] In the production processes of glycosylation, daily chemical products, oil saponification, and biodiesel, a large amount of crude glycerol and polysaccharides containing impurities are generated. To improve the efficiency of subsequent refining, crude glycosides and glycerol need to be pre-filtered to remove impurities such as solid particles, soap residue, catalyst residue, and residual sugar. Traditional crude glycoside filters mostly use manual or semi-automatic methods to clean the filter residue, which has the following problems: high labor intensity; periodic shutdowns are required to disassemble the filter and manually remove the accumulated residue on the filter screen or filter element; poor production continuity; manual cleaning cannot guarantee complete removal of residues each time; high labor intensity; and problems affecting filtration efficiency, on-site employee safety, and difficulty in controlling the production environment. Therefore, this utility model proposes an automatic slag discharge structure for crude glycoside filters. Summary of the Invention

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 As shown, this utility model provides a technical solution: an automatic slag discharge structure for a crude glycoside filter, including a housing 1, a filter assembly 2, a slag collection chamber 3, a slag discharge mechanism 4, and a flushing mechanism 5. This utility model achieves rapid and automatic removal of filter residue during the crude glycoside filtration process by setting a slag collection chamber 3 at the bottom of the filter, and cooperating with the slag discharge mechanism 4 and the flushing mechanism 5, thereby ensuring the efficiency of cleaning filter residue in the crude glycoside filter. Moreover, the fully enclosed slag discharge path avoids material leakage, improves the working environment, and reduces safety risks.

[0018] In this application, the shell 1 is a vertical cylindrical structure, with a feed inlet 11 at the top and a clear liquid outlet 12 at the bottom of the side wall of the shell 1.

[0019] In this application, the filter assembly 2 is located in the upper middle part of the inner cavity of the housing 1. The filter assembly 2 is a conical filter screen, and a cylindrical housing 21 is connected to the bottom center of the conical filter screen.

[0020] In this application, the slag discharge mechanism 4 includes a spiral feed rod 41 installed inside the cylindrical housing 21. The top of the spiral feed rod 41 is connected to a drive motor 42, which is fixedly installed on the top of the housing 1.

[0021] In this application, the flushing mechanism 5 includes a plurality of high-pressure backwashing nozzle array 1 51 and high-pressure backwashing nozzle array 2 52 arranged circumferentially along the inner wall of the slag collection chamber. The output end of the high-pressure backwashing nozzle array 1 51 faces the lower surface of the conical filter screen, and the high-pressure backwashing nozzle array 2 52 faces the inner wall of the slag collection chamber 3.

[0022] Please refer to the following carefully. Figure 3 and Figure 4 The high-pressure backwash nozzle array 1 51 and the high-pressure backwash nozzle array 2 52 are connected to the feed pipe 54 through the connecting pipe 53. The connecting pipe 53 is equipped with solenoid valves 55 that control the high-pressure backwash nozzle array 1 51 and the high-pressure backwash nozzle array 2 52 respectively. The feed pipe 54 is connected to the conveying end, which is used to output compressed air, steam or process recycled clean liquid.

[0023] Please refer to the following carefully. Figure 2 and Figure 3The shell 1 is equipped with a sealing partition 6, and below the sealing partition 6 is a slag collection chamber 3. The slag collection chamber 3 is equipped with a slag discharge port 31 at the bottom, and a slag discharge valve 32 is installed at the slag discharge port 31.

[0024] Working principle: When the automatic slag discharge structure of this utility model is in operation, the crude glycoside material enters the inner cavity of the shell 1 through the feed port 11 at the top of the shell 1. The material first flows through the conical filter screen, i.e., the filter component 2, located in the upper middle part. The liquid component flows downward through the pores of the filter screen and is discharged from the clear liquid outlet 12 at the lower part of the side wall of the shell; while solid impurities are trapped on the inner surface of the conical filter screen and, under the action of gravity, collect downward along the conical surface to the cylindrical shell 21 area at the bottom center.

[0025] During slag discharge, the control system starts the drive motor 42, which drives the spiral feed rod 41 installed inside the cylindrical shell 21 to rotate. The spiral feed rod forces the filter slag that has accumulated at the bottom of the conical filter screen to the bottom of the slag collection chamber 3, and finally discharges it through the slag discharge port 31. The slag discharge valve 32 is opened in a controlled manner to complete the sealed slag discharge.

[0026] Simultaneously with slag discharge, the flushing mechanism 5 works in concert: the high-pressure medium, which can be compressed air, steam, or process recycled liquid, is conveyed via the feed pipe 54 and supplied to two sets of high-pressure backwash nozzle arrays through the connecting pipe 53. High-pressure backwash nozzle array one 51 sprays towards the lower surface of the conical filter screen to peel off residual filter cake adhering to the back of the screen; high-pressure backwash nozzle array two 52 is arranged circumferentially along the inner wall of the slag collection chamber 3 to flush the chamber wall and prevent filter cake adhesion and agglomeration. The opening and closing of the two sets of nozzles are independently controlled by their respective solenoid valves 55, allowing for selective activation according to process requirements.

[0027] The entire slag discharge and rinsing process is completed in a fully enclosed shell, effectively avoiding material leakage and environmental pollution, and realizing the efficient, safe and continuous operation of the crude glycoside filter.
