Description

Technical Field

[0001] This utility model relates to the field of cresol filtration and purification technology, specifically a small cresol purification device with a dual-stage filtration structure. Background Technology

[0002] Cresol, with the chemical formula C7H8O, has three isomers: ortho, meta, and para. This product is a mixture of various cresol isomers obtained by fractionation from coal tar. It is a nearly colorless, pale purple-red, or pale brownish-yellow clear liquid with an odor similar to phenol and a slight burnt smell. Upon prolonged storage or exposure to sunlight, its color gradually darkens. A saturated aqueous solution exhibits a neutral or weakly acidic reaction.

[0003] When cresol is recycled and produced, it needs to be purified to maintain its purity. Because the cresol raw material may contain large particulate impurities such as mechanical particles, unreacted raw materials, and polymer residues, it needs to be screened and filtered. Common screening and filtration methods generally use tools such as vibrating screens to screen and purify the cresol. If there are many large particles remaining in the cresol raw material, the screen can easily become clogged, affecting the efficiency and effectiveness of the cresol raw material purification.

[0004] Therefore, we propose a small cresol purification device with a two-stage filtration structure. Utility Model Content

[0005] The purpose of this invention is to provide a small cresol purification device with a dual-stage filtration structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a small cresol purification device with a dual-stage filtration structure, comprising a processing box, a support leg fixedly connected to the bottom of the processing box, a primary filter assembly installed inside the processing box at the top, used for preliminary screening and purification of cresol raw materials, used to filter larger impurities in the cresol raw materials, and a secondary filter assembly installed inside the processing box at the bottom, used for secondary screening and purification of the cresol raw materials after screening and purification by the primary filter assembly. The secondary filter assembly and the primary filter assembly work together to improve the cresol filtration and purification effect.

[0007] Preferably, the primary filtration assembly includes a drive motor, which is fixedly connected to the bottom surface of the support leg. The output shaft of the drive motor passes through the bottom wall of the processing box and is rotatably connected to the processing box. The output shaft of the drive motor is fixedly connected to a rotating shaft, and a perforated box is fixedly connected to the top end of the rotating shaft.

[0008] Preferably, the upper surface of the processing box is equipped with [something].

[0009] Preferably, a tapered baffle is fixedly connected to the bottom wall of the orifice box.

[0010] Preferably, the secondary filtration assembly includes a support ring fixedly connected to the inner wall of the processing box. A guide slope is placed on the upper surface of the support ring, and a perforated plate is fixedly connected to the lower part of the inner ring of the guide slope. The perforated plate is inserted into the rotating shaft. Four rectangular grooves are formed on the bottom surface of the guide slope. Four sliders that engage with the grooves are fixedly connected to the upper surface of the support ring. A fixed disk is fixedly connected to the outer surface of the rotating shaft. Several second collision balls are fixedly connected to the upper surface of the fixed disk. Several first collision balls are fixedly connected to the bottom surface of the perforated plate. The second collision balls and the first collision balls are on the same circumference.

[0011] Preferably, a return spring is fixedly connected between the upper surface of each slider and the top wall of the groove.

[0012] Preferably, a spherical baffle is fixedly connected to the upper surface of the perforated plate, and the spherical baffle is inserted into the rotating shaft.

[0013] Preferably, each of the sliders and grooves is T-shaped, and the sliders have a smooth outer surface.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. When purifying cresol raw materials, sieving is required. First, remove the top of the processing box, then add the cresol raw materials into the orifice box, and then cover the top of the processing box. At this time, turn on the power switch connected to the drive motor. The output shaft of the drive motor will drive the rotating shaft to rotate, which in turn drives the orifice box to rotate. Then, the cresol raw materials inside the orifice box will be thrown out by centrifugal force, leaving larger impurities inside the orifice box. The conical baffles prevent the added raw materials from accumulating at the center of the bottom wall of the orifice box.

[0016] By setting up a primary filtration component, the centrifugal force can be used to perform preliminary filtration and screening of the cresol raw material when the pore box rotates.

[0017] 2. When the cresol material ejected from the orifice box slides down the guide slope onto the surface of the orifice plate, the rotation of the rotating shaft causes the fixed disc to rotate synchronously. At this time, the second collision ball fixedly connected to the upper surface of the orifice box will continuously collide with the first collision ball. Through the locking action of the guide slope and the slider, when the second collision ball contacts the first collision ball, the orifice plate will move upward a bit. When the second collision ball does not contact the first collision ball, under the action of the return spring and the influence of the gravity of the orifice plate and the guide slope, the orifice plate will quickly return downward, until the cycle continues. This achieves the purpose of vibrating the orifice plate, allowing the orifice plate to perform secondary filtration and screening of the cresol material on its surface. By setting spherical baffles, the cresol material can be prevented from getting stuck in the gap between the rotating shaft and the orifice plate.

[0018] By setting up a two-stage filtration system, the cresol raw material can be screened once by centrifugal force through the first-stage filtration system and then vibrated and screened again through the second-stage filtration system, which can further improve the filtration and purification effect of the cresol raw material.

Detailed Implementation

[0024] 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.

[0025] Please see Figures 1-4This utility model provides a technical solution:

[0026] Example 1: A small cresol purification device with a dual-stage filtration structure includes a processing box 3, with support legs 4 fixedly connected to the bottom of the processing box 3, a primary filter assembly 1 installed inside the processing box 3 at the top, used for preliminary screening and purification of cresol raw materials, and used to filter out larger impurities in the cresol raw materials, and a secondary filter assembly 2 installed inside the processing box 3 at the bottom, used for secondary screening and purification of the cresol raw materials after screening and purification by the primary filter assembly 1. The secondary filter assembly 2 and the primary filter assembly 1 work together to improve the cresol filtration and purification effect.

[0027] The primary filter assembly 1 includes a drive motor 5, which is fixedly connected to the bottom surface of the support leg 4. The output shaft of the drive motor 5 passes through the bottom wall of the processing box 3 and is rotatably connected to the processing box 3. The output shaft of the drive motor 5 is fixedly connected to a rotating shaft 6, and a perforated box 7 is fixedly connected to the top end of the rotating shaft 6.

[0028] The upper surface of the processing box 3 is equipped with 19.

[0029] A tapered baffle 8 is fixedly connected to the bottom wall of the orifice box 7.

[0030] When cresol raw materials need to be purified, they need to be screened. First, remove 19 from the top of the processing box 3. Then, add the cresol raw materials into the orifice box 7. Next, cover the top of the processing box 3 with 19. At this time, turn on the power switch that is electrically connected to the drive motor 5. The output shaft of the drive motor 5 can drive the rotating shaft 6 to rotate, which in turn drives the orifice box 7 to rotate. Then, the cresol raw materials inside the orifice box 7 will be thrown out from the orifice box 7 due to the centrifugal force, leaving larger impurities inside the orifice box 7. The conical baffle 8 can prevent the added raw materials from accumulating at the center of the bottom wall of the orifice box 7.

[0031] By setting up the primary filter component 1, the centrifugal force can be used to perform preliminary filtration and screening of the cresol raw material when the perforated box 7 rotates.

[0032] Example 2: The secondary filter assembly 2 includes a support ring 9, which is fixedly connected to the inner wall of the processing box 3. A guide slope 12 is placed on the upper surface of the support ring 9. A perforated plate 11 is fixedly connected to the lower part of the inner ring of the guide slope 12. The perforated plate 11 is inserted into the rotating shaft 6. Four rectangular grooves 13 are opened on the bottom surface of the guide slope 12. Four sliders 10 that engage with the grooves 13 are fixedly connected to the upper surface of the support ring 9. A fixed disk 17 is fixedly connected to the outer surface of the rotating shaft 6. Several second collision balls 16 are fixedly connected to the upper surface of the fixed disk 17. Several first collision balls 15 are fixedly connected to the bottom surface of the perforated plate 11. The second collision balls 16 and the first collision balls 15 are on the same circumference.

[0033] A return spring 14 is fixedly connected between the upper surface of each slider 10 and the top wall of the groove 13.

[0034] A spherical baffle 18 is fixedly connected to the upper surface of the perforated plate 11, and the spherical baffle 18 is inserted into the rotating shaft 6.

[0035] Each slider 10 and groove 13 is T-shaped, and the slider 10 has a smooth outer surface.

[0036] When the cresol material is ejected from the orifice box 7, it slides onto the surface of the orifice plate 11 via the guide slope 12. At this time, the rotation of the rotating shaft 6 causes the fixed disk 17 to rotate synchronously. The second collision ball 16, which is fixedly connected to the upper surface of the orifice box 7, will continuously collide with the first collision ball 15. Through the locking action of the guide slope 12 and the slider 10, when the second collision ball 16 collides with the first collision ball 15, the orifice plate 11 will move upward a bit. When the second collision ball 16 does not contact the first collision ball 15, under the action of the return spring 14 and the influence of the gravity of the orifice plate 11 and the guide slope 12, the orifice plate 11 will quickly return downward until the cycle continues. At this time, the orifice plate 11 can be vibrated, which allows the orifice plate 11 to perform secondary filtration and screening of the cresol material on its surface. By setting the spherical baffle 18, the cresol material can be prevented from getting stuck in the gap between the rotating shaft 6 and the orifice plate 11.

[0037] By setting up a secondary filter component 2, the cresol raw material can be screened once by centrifugal force through the primary filter component 1 and then vibrated and screened through the secondary filter component 2, which can further improve the filtration and purification effect of the cresol raw material.
