Description

Technical Field

[0001] This utility model relates to the technical field of belt vacuum filter, specifically an improved mesitylene separation belt vacuum filter. Background Technology

[0002] A belt vacuum filter is a continuous filtration device that uses vacuum suction to achieve solid-liquid separation. It is one of the commonly used filtration devices in the processing of mesitylene. Its working principle is as follows:

[0003] Feeding: The slurry is evenly distributed on the horizontally moving filter belt by the distributor;

[0004] Vacuum dehydration: A vacuum chamber is located below the filter belt. The negative pressure generated by the vacuum pump draws the liquid into the filtrate collection system, and solid particles are trapped on the surface of the filter belt to form a filter cake.

[0005] Washing and drying (optional): The filter cake can be washed by multi-stage spraying to further remove impurities or soluble components; the degree of dryness can be improved by extending the vacuum zone or by hot air assistance.

[0006] Unloading: When the filter belt reaches the end, the filter cake is peeled off by a scraper or roller, and the filter belt is cleaned and reused.

[0007] The following problems also exist when filtering mesitylene using a belt vacuum filter:

[0008] Fine particles of mesitylene can easily clog the pores of filter cloth, leading to a decrease in filtration efficiency and requiring frequent cleaning or replacement of the filter cloth. This can affect the continuous production of mesitylene and is not conducive to the efficient production of mesitylene. Based on this, an improved mesitylene separation belt vacuum filtration device is provided. Utility Model Content

[0029] 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.

[0030] Please see Figures 1-3 In this embodiment of the present invention, an improved succinate separation belt vacuum filter includes a belt vacuum filter 1 consisting of a filter body 101 and a filter belt 102. The filter belt 102 is installed inside the frame of the filter body 101 by multiple conveying rollers. The discharge end of the frame of the filter body 101 is provided with a discharge anti-blocking component 2, which is used to clean the material on the surface of the filter belt 102.

[0031] The unloading anti-clogging component 2 includes an unloading component and a backflushing component. The unloading component is used to provide a material guiding operation for unloading material from the surface of the filter belt 102, and the backflushing component is used to perform a backflushing operation on the filter belt 102 after unloading, thereby achieving the cleaning operation of residual material on the surface of the filter belt 102.

[0032] The unloading assembly includes a guide plate 201 and an unloading scraper 202;

[0033] The guide plate 201 is fixed to the inner side of the discharge end of the filter body 101 frame and close to the top surface of the guide plate 201 near the bend of the filter belt 102;

[0034] The unloading scraper 202 is fixed to the inside of the guide plate 201 and protrudes from the top of the guide plate 201 and is in contact with the curved surface of the filter belt 102. The unloading scraper 202 is used to scrape off the material on the surface of the filter belt 102, and the guide plate 201 is used to provide material unloading operation.

[0035] The backflushing assembly includes a receiving hopper 203, an air knife 204, and a connecting pipe port 205;

[0036] The receiving hopper 203 is fixed to the bottom of the guide plate 201. The air knife 204 is installed inside the frame of the filter body 101 and is distributed inside the filter belt 102. The nozzle of the air knife 204 faces the inner surface of the filter belt 102. The connecting pipe 205 is fixed to one side of the air knife 204 and communicates with the inner cavity of the air knife 204.

[0037] The filter belt 102 and the air knife 204 are located inside the connecting pipe 205. Air is supplied to the air knife 204 through the connecting pipe 205. The air is ejected through the air knife 204 to create a backflow on the filter belt 102, which is used to blow the residual material on the surface of the filter belt 102 into the receiving hopper 203.

[0038] In this embodiment, it should be noted that the belt vacuum filter 1 is a common model of belt vacuum filter on the market. Its operating principle and structure are exactly the same, so it will not be described in detail here. In addition, the connecting pipe 205 is connected to the external fan through the pipe.

[0039] When the belt vacuum filter 1 is running, the filter belt 102 can transport the filtered tetramethylbenzene material to the unloading anti-clogging component 2 area. When the filter belt 102 turns downward, the unloading scraper 202 can scrape off the tetramethylbenzene material on the surface of the filter belt 102. The scraped-off tetramethylbenzene material slides down the inclined surface of the guide plate 201 to achieve unloading.

[0040] After unloading, the filter belt 102 continues to run into the receiving hopper 203. There are still residual material particles in the pores of the filter cloth 102. At this time, the external fan is started simultaneously. The fan drives air into the air knife 204 and sprays it out through the nozzle of the air knife 204, thereby realizing the back-blowing operation of the filter cloth 102 from the inside out. In this way, the residual material particles in the pores of the filter cloth 102 are blown out and carried into the receiving hopper 203, achieving the effect of cleaning and preventing clogging of the filter cloth 102. This allows the filter cloth 102 to maintain a high-efficiency filtration effect for a longer time, thereby reducing the number of downtimes caused by the replacement of the filter cloth 102.

[0041] Please refer to this carefully. Figures 2-3 The two side plates of the receiving hopper 203 are connected to the air knife 204. The filter belt 102 passes through the middle of the two side plates of the flow-blocking filter plate 206, and the width of the blowing nozzle of the air knife 204 matches the width of the filter belt 102.

[0042] In this embodiment: the two side plates of the receiving hopper 203 can block both sides of the filter belt 102, which can improve the back-blowing effect of the air knife 204 on the filter belt 102, and at the same time prevent the blown material from scattering.

[0043] Please refer to this carefully. Figure 3 A flow-blocking filter plate 206 is fixed on the lower surface of the guide plate 201, and multiple flow-blocking filter plates 206 are arranged sequentially along the inclined surface of the guide plate 201.

[0044] The nozzle of the air knife 204 is tilted upwards and aligned with the highest flow-blocking filter plate 206.

[0045] In this embodiment, when the airflow blown out by the air knife 204 passes through the filter cloth 102 and enters the receiving hopper 203, it is blocked by multiple flow-blocking filter plates 206, thereby reducing the airflow speed and making the airflow at the discharge port of the receiving hopper 203 slow down. At the same time, the flow-blocking filter plates 206 can intercept the material particles blown out by the airflow. After the material particles are intercepted when they encounter the flow-blocking filter plates 206, they fall naturally to the bottom of the receiving hopper 203 and then slide down the inclined surface at the bottom of the receiving hopper 203 for discharge.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
