Description

Technical Field

[0001] This utility model relates to the field of formaldehyde removal material production technology, specifically a raw material grinding device for the production of formaldehyde removal materials. Background Technology

[0002] The core methods of formaldehyde removal materials can be divided into adsorption, chemical decomposition, plant-based, and equipment-assisted methods. Formaldehyde removal materials that need to be ground mainly include activated carbon and activated manganese. Activated carbon needs to be ground by a grinder when used as a formaldehyde removal material.

[0003] The announcement number is CN218132095U, which discloses "an activated carbon grinding device, including a worktable and a grinding tank. The grinding tank is rotatably mounted on the worktable in the middle. Support columns are fixedly connected to the four corners of the bottom of the worktable. Grinding blocks adapted to the grinding tank are provided in the grinding tank. An L-shaped bracket is installed on one side of the worktable. A hydraulic cylinder is installed on the top of the L-shaped bracket. The hydraulic cylinder is used to drive the grinding blocks to move up and down. The device also includes a drive assembly for driving the grinding tank to rotate. The grinding blocks have a receiving groove inside, and coolant is injected into the receiving groove."

[0004] There are still some drawbacks in its use. The activated carbon powder passes through the conical grinding tank that is wider at the top and narrower at the bottom. As the activated carbon powder passes through the tank, the feeding path gradually narrows. However, the area occupied by the activated carbon powder increases after it is spread out during grinding. When the activated carbon powder has a high moisture content, it is easy for the powder to stick to the surface of the grinding disc and be discharged from the bottom of the grinding tank in clumps. This results in poor grinding accuracy, and the sticky activated carbon powder also affects the feeding rate. Utility Model Content

[0005] The purpose of this invention is to provide a raw material grinding device for the production of formaldehyde removal materials, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A raw material grinding apparatus for the production of formaldehyde removal materials, comprising:

[0008] Grinding chamber;

[0009] A grinding assembly is disposed inside a grinding chamber. The grinding assembly includes a grinding base fixedly installed inside the grinding chamber. A first grinding disc is movably disposed inside the grinding base. A second grinding disc is fixedly installed on the upper end of the first grinding disc. A first motor is fixedly installed on the upper end of the grinding chamber. Multiple levers are fixedly installed at equal angles on the upper surface of the second grinding disc.

[0010] An adsorption component is disposed on the outer surface of the grinding chamber;

[0011] The volatile component is located on one side of the adsorption component.

[0012] Furthermore, a feed pipe is fixedly embedded in the upper end of the grinding chamber, an air inlet pipe is fixedly embedded in the upper end of the grinding chamber, and a discharge pipe is fixedly installed in the lower end of the grinding chamber.

[0013] Furthermore, a rotating shaft is fixedly installed on the upper surface of the second grinding disc, a support frame is fixedly installed at the lower end of the interior of the grinding chamber, and a support rod is fixedly installed on the lower surface of the first grinding disc. The support rod and the support frame are rotatably connected by bearings.

[0014] Furthermore, the adsorption component includes:

[0015] Adsorption chamber, fixedly installed on the outer surface of the grinding chamber;

[0016] Filter cartridge number one is fixedly installed on the inner surface of the adsorption chamber;

[0017] The second filter cartridge is fixedly installed on the inner surface of the first filter cartridge.

[0018] Preferably, a spiral blade is rotatably connected between the first filter cartridge and the second filter cartridge, and one end of the spiral blade rotates through the first filter cartridge and the adsorption chamber. A second motor capable of driving the spiral blade to rotate is fixedly installed at one end of the adsorption chamber.

[0019] Furthermore, the evaporation component includes:

[0020] The evaporation tube is fixedly installed on one side of the adsorption chamber;

[0021] Two connecting pipes are symmetrically and fixedly embedded on the outer surface of the evaporation pipe, and the connecting pipes are fixedly inserted through the adsorption chamber and the No. 1 filter cartridge;

[0022] The heating ring is fixedly installed on the outer surface of the evaporation tube;

[0023] The stirring rod is rotatably connected to the inside of the evaporation tube.

[0024] Preferably, a No. 3 motor capable of driving the stirring rod to rotate is fixedly installed at one end of the evaporation tube, a solenoid valve is fixedly installed at the upper end of the evaporation tube, and an exhaust fan is fixedly installed at the upper end of the solenoid valve.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] 1. Driven by motor number one, activated carbon is fed into the grinding chamber through the feed pipe, causing it to fall between the second grinding disc and the grinding seat. The gradually narrowing space pulverizes the larger activated carbon particles into smaller ones. The first grinding disc rotates to grind the activated carbon powder. Simultaneously, protective gas flows from top to bottom, blowing the activated carbon powder that meets the grinding requirements downwards. By adopting a conical feeding structure that is smaller at the top and larger at the bottom, the activated carbon powder is spread out and laid on the surface of the first grinding disc after grinding, increasing the feeding path of the activated carbon powder and preventing it from sticking together and narrowing its feeding path. At the same time, the protective gas causes the ground activated carbon powder to be discharged from below, giving the activated carbon powder an active downward force and accelerating the feeding rate.

[0027] 2. Nitrogen gas enters from the top of the grinding chamber and exits from the bottom into the bag filter, then flows into the adsorption chamber, and finally exits into the adsorption chamber, thus circulating the nitrogen gas. The water vapor in the nitrogen gas is adsorbed by the adsorption medium, reducing the moisture content of the nitrogen gas and preventing the increase in moisture during nitrogen circulation from increasing the humidity of the activated carbon. The second motor runs, driving the spiral blades to rotate and agitate the adsorption medium, which enters the evaporation tube from the upper connecting pipe and then enters the first filter cartridge from the lower connecting pipe, thus circulating the adsorption medium. Then, the heating ring operates to heat the evaporation tube, causing the water vapor in the adsorption medium to evaporate. The solenoid valve opens, the exhaust fan runs, and the water vapor inside the evaporation tube is discharged, allowing the adsorption medium to be recycled. Attached Figure Description

[0034] 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.

[0035] Please see Figure 1-5 In this embodiment of the present invention, a raw material grinding device for the production of formaldehyde removal materials includes a grinding chamber 1. A feed pipe 101 is fixedly embedded in the upper end of the grinding chamber 1, an air inlet pipe 102 is fixedly embedded in the upper end of the grinding chamber 1, and a discharge pipe 103 is fixedly installed in the lower end of the grinding chamber 1. The air inlet pipe 102 is connected to the pipe at the upper end of the second filter cartridge 303. A grinding component 2 is disposed inside the grinding chamber 1. The grinding component 2 includes a grinding seat 201 fixedly installed inside the grinding chamber 1. A first grinding disc 202 is movably disposed inside the grinding seat 201. A second grinding disc 203 is fixedly installed on the upper end of the first grinding disc 202. A first motor 208 is fixedly installed on the upper end of the grinding chamber 1 to drive the first grinding disc 202 and the second grinding disc 203 to rotate. Multiple levers 204 are fixedly installed at equal angles on the upper surface of the second grinding disc 203. An adsorption component 3 is disposed on the outer surface of the grinding chamber 1, and a volatilization component 4 is disposed on one side of the adsorption component 3.

[0036] Specifically, the discharge pipe 103 is connected to the external bag filter, and the gas supply pipe at the lower end of the adsorption chamber 301 is connected to the exhaust pipe of the external bag filter. By introducing protective gas, the gas carries activated carbon powder into the bag filter, collects the activated carbon powder, and circulates the protective gas. During the circulation of the protective gas, it is adsorbed by the adsorption component 3, and the volatilization component 4 treats the water vapor inside the adsorption medium.

[0037] Example 1

[0038] like Figure 2 and Figure 3As shown, in this embodiment, a rotating shaft 207 is fixedly installed on the upper surface of the second grinding disc 203, a support frame 205 is fixedly installed at the lower end of the grinding chamber 1, and a support rod 206 is fixedly installed on the lower surface of the first grinding disc 202. The support rod 206 and the support frame 205 are rotatably connected by a bearing. The first grinding disc 202 is supported by the support rod 206 rotating inside the support frame 205.

[0039] In this embodiment, motor 208 operates, and activated carbon is fed into the grinding chamber 1 through feed pipe 101. The activated carbon falls between grinding disc 203 and grinding seat 201, where the larger activated carbon is pulverized into smaller particles through a gradually narrowing space. Simultaneously, lever 204 moves the activated carbon to distribute it evenly. Then, grinding disc 202 rotates to grind the activated carbon powder. At the same time, protective gas flows from top to bottom, blowing the activated carbon powder that meets the grinding requirements downwards. By adopting a conical feeding structure that is smaller at the top and larger at the bottom, the activated carbon powder is spread out and laid on the surface of grinding disc 202 after grinding, increasing the feeding path of the activated carbon powder and preventing it from sticking together and narrowing its feeding path. At the same time, the protective gas causes the ground activated carbon powder to be discharged from below, giving the activated carbon powder an active downward force and accelerating the feeding rate.

[0040] like Figure 3-5 As shown, in this embodiment, the adsorption assembly 3 includes: an adsorption chamber 301 fixedly installed on the outer surface of the grinding chamber 1, an opening communicating with a first filter cartridge 302 on the outer side of the adsorption chamber 301 for filling with an adsorption medium (e.g., a molecular sieve), a first filter cartridge 302 fixedly installed on the inner surface of the adsorption chamber 301, and a second filter cartridge 303 fixedly installed on the inner surface of the first filter cartridge 302; a spiral blade 305 rotatably connects the first filter cartridge 302 and the second filter cartridge 303, and one end of the spiral blade 305 rotatably passes through the first filter cartridge 302 and the adsorption chamber 301; a second motor 304 capable of driving the spiral blade 305 to rotate is fixedly installed at one end of the adsorption chamber 301.

[0041] In practice, nitrogen gas is introduced from the top of the grinding chamber 1 and discharged from the bottom into the bag filter. Then it is introduced into the adsorption chamber 301 and finally discharged into the adsorption chamber 301, so that the nitrogen gas circulates. The nitrogen gas enters the adsorption chamber 301 and flows through the first filter cartridge 302, the adsorption medium and the second filter cartridge 303. Then it is discharged into the inlet pipe 102 from the pipe at the top of the second filter cartridge 303. The water vapor in the nitrogen gas is adsorbed by the adsorption medium, reducing the moisture in the nitrogen gas and preventing the increase of water vapor during nitrogen gas circulation from increasing the humidity of the activated carbon. The second motor 304 operates, driving the spiral blades 305 to rotate, so that the adsorption medium can circulate in conjunction with the volatilization component 4.

[0042] Example 2

[0043] Based on Example 1, in order to compensate for the problem that the adsorption medium inside the No. 1 filter cartridge 302 is not easy to recycle.

[0044] like Figure 4 As shown, in this embodiment, the evaporation assembly 4 includes: an evaporation tube 401 fixedly disposed on one side of the adsorption chamber 301; two connecting tubes 402 symmetrically fixedly embedded in the outer surface of the evaporation tube 401, and the connecting tubes 402 fixedly penetrating the adsorption chamber 301 and the first filter cartridge 302; a heating ring 403 fixedly disposed on the outer surface of the evaporation tube 401; and a stirring rod 404 rotatably connected to the inside of the evaporation tube 401. A third motor 405 capable of driving the stirring rod 404 to rotate is fixedly installed at one end of the evaporation tube 401, and a solenoid valve 406 is fixedly installed at the upper end of the evaporation tube 401. An exhaust fan 407 is fixedly installed at the upper end of the solenoid valve 406.

[0045] In practice, the spiral blades 305 agitate the adsorption medium, which enters the evaporation tube 401 from the upper connecting pipe 402 and then enters the first filter cartridge 302 from the lower connecting pipe 402, causing the adsorption medium to circulate. Then, the heating ring 403 operates to heat the evaporation tube 401, causing the water vapor in the adsorption medium to evaporate. The solenoid valve 406 opens, and the exhaust fan 407 operates, expelling the water vapor inside the evaporation tube 401, so that the adsorption medium can be recycled.
