Description

Technical fields:

[0001] This utility model relates to the technical field of furfural production equipment, specifically a furfural residue separation device. Background technology:

[0002] Furfural residue is generated during the production of furfural. Furfural residue is a biomass substance, mainly derived from the residue of biomass raw materials (such as corn cobs, sawdust, straw, etc.) after being hydrolyzed under acidic conditions to produce furfural.

[0003] The prior art discloses a waste residue separation device for furfural production, which cleans the waste residue attached to the filter screen by friction between a cleaning brush and a rotating filter screen. However, the waste residue itself is wet and easily sticks to the cleaning brush during the cleaning process. Therefore, the cleaning effect of the prior art needs to be improved. Utility Model Content:

[0004] The purpose of this invention is to provide a furfural residue separation device to solve the problems mentioned in the background art.

[0005] This utility model is implemented by the following technical solution:

[0006] A furfural residue separation device includes a base support, a cylindrical body fixedly at the top of the base support, four pairs of rolling wheels installed on the inner wall of the cylindrical body, one pair of rolling wheels connected by a drive shaft, one end of the drive shaft extending out of the outer side of the cylindrical body and fixed with a driven pulley, a drive motor fixed on the base support, a drive pulley fixed on the output shaft of the drive motor, the driven pulley and the drive pulley connected by a belt drive, a filter cylinder rotatably disposed inside the cylindrical body, the filter cylinder being placed between the four pairs of rolling wheels, the outer surface of the filter cylinder being in movable contact with the surfaces of the four pairs of rolling wheels, a cross support fixed at the end of the filter cylinder near the discharge, a sphere movably disposed in the middle of the cross support, a pressure roller placed inside the filter cylinder, one end of the pressure roller having an annular groove, the groove surface of the annular groove being arc-shaped, the sphere being movably disposed within the annular groove, a support rod fixedly disposed on the inner side of the top of the cylindrical body, multiple inclined arc-shaped scrapers evenly fixed on the support rod, the upper surface of the arc-shaped scrapers being in movable contact with the inner surface of the filter cylinder.

[0007] Preferably, an arc-shaped chute is fixed at the discharge port of the cylinder, the arc-shaped chute having a large inlet and a small outlet and being truncated cone-shaped, and a drain pipe is provided at the bottom of the cylinder.

[0008] Preferably, a layer of filter cloth is adhered to the inner wall surface of the filter cartridge.

[0009] The advantages of this utility model are: the structure is relatively simple. The pressure roller rotates with the filter cylinder and rolls inside it, so that the furfural residue is continuously squeezed, making it easier to separate the residue from the liquid. By fixing multiple inclined arc-shaped scrapers on the top of the cylinder, the furfural residue is not easy to stick to the filter cylinder or filter screen by using the weight of the arc-shaped scrapers and the furfural residue.

[0018] 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.

[0019] Please see Figure 1-7 This utility model provides a technical solution for a furfural residue separation device:

[0020] A furfural residue separation device includes a base support 1, a cylinder 2 fixedly at the top of the base support 1 at an incline, and a filter cylinder 8 rotatably installed inside the cylinder 2. The incline facilitates the downward discharge of furfural residue inside the filter cylinder 8. The filter cylinder 8 is used to filter the residual residue liquid in the furfural residue. Four pairs of rolling wheels 3 are installed on the inner wall of the cylinder 2. One pair of rolling wheels 3 is connected by a drive shaft 4. One end of the drive shaft 4 extends out of the outer side of the cylinder 2 and is fixed with a driven pulley 5. A drive motor 6 is fixed on the base support 1. A drive pulley 7 is fixed on the output shaft of the drive motor 6. The driven pulley 5 and the drive pulley 7 are connected by a belt drive. The filter cylinder 8 is placed between the four pairs of rolling wheels 3, and the outer surface of the filter cylinder 8 is in movable contact with the surfaces of the four pairs of rolling wheels 3. The rotation of the output shaft of the drive motor 6 drives one pair of rolling wheels 3 to rotate, thereby driving the filter cylinder 8 to rotate.

[0021] A pressure roller 11 is placed inside the filter cylinder 8. Since both the cylinder body 2 and the filter cylinder 8 are inclined, a cross bracket 9 is fixed at the end of the filter cylinder 8 near the discharge end to prevent the pressure roller 11 from slipping out. A ball 10 is movably installed in the middle of the cross bracket 9. An annular groove 11.1 is opened at one end of the pressure roller 11. The groove surface of the annular groove 11.1 is arc-shaped. The ball 10 is movably placed in the annular groove 11.1, so that no matter how fast the filter cylinder 8 rotates, the pressure roller 11 remains stationary relative to its position during the rotation of the filter cylinder 8. After the filter cylinder 8 rotates, furfural residue is put into the filter cylinder 8. The weight of the pressure roller 11 quickly squeezes the residue liquid in the furfural residue, causing the residue liquid to seep through the filter cylinder 8 and drip into the cylinder body 2.

[0022] To prevent furfural residue from adhering to the inner wall of the filter cylinder 8 after being squeezed and difficult to remove, a support rod 12 is fixed on the inner side of the top of the cylinder 2. Multiple inclined arc-shaped scrapers 13 are evenly fixed on the support rod 12. The upper surface of the arc-shaped scrapers 13 is in contact with the inner surface of the filter cylinder 8. The furfural residue on the filter cylinder 8 is scraped off along the discharge direction by the inclined arc-shaped scrapers 13.

[0023] To prevent the filter cartridge 8 from clogging, a layer of filter cloth 16 can be adhered to the inner wall surface of the filter cartridge 8. In the future, only the filter cloth 16 needs to be replaced periodically.

[0024] An arc-shaped chute 14 is fixed at the discharge port of the cylinder 2. The arc-shaped chute 14 has a large inlet and a small outlet and is truncated cone-shaped.

[0025] The bottom of the cylinder 2 is equipped with a drain pipe 2.1 for draining the sludge liquid in the furfural residue.

[0026] The working principle is as follows: After the drive motor 6 starts, the driven pulley 5 and the driving pulley 7 rotate synchronously. The driven pulley 5 drives a pair of rolling wheels 3 to rotate. The rotation of the rolling wheels 3 drives the filter cylinder 8 to rotate. The pressure roller 11 rolls relative to the filter cylinder 8. By feeding furfural residue into the filter cylinder 8, the furfural residue tumbles inside the filter cylinder 8 and is squeezed multiple times by the pressure roller 11, causing the residue liquid inside the furfural residue to separate from the filter cylinder 8.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
