There are various types of flame retardants, which are divided into additive flame retardants and reactive flame retardants according to the usage method. Flame retardants can increase the flame resistance of polymer materials and are mainly used in polymer materials such as plastics, rubbers, and fibers. Flame retardants play their flame retardant role through several mechanisms, such as endothermic action, covering action, inhibiting chain reaction, and the asphyxiating action of non-combustible gases.

[0003] In the prior art, as disclosed in Chinese Patent No.: CN214078043U, a washing device for flame retardant processing is disclosed.

The triangular slider can quickly and thoroughly remove the washed sewage.

[0004] In the above patent, although the flame retardant can be washed, when there are many flame retardant particles and they accumulate in the mesh washing box, the flame retardant particles will block each other, resulting in a poor washing effect. Moreover, when flushing with a pressurized water gun, the flame retardant particles are easily broken, affecting their performance and quality. Therefore, the utility model provides a washing device for flame retardant processing. Summary of the Utility Model

[0013] Advantageous Effects

[0014] The utility model provides a washing device for flame retardant processing. Compared with the prior art, the following advantageous effects are achieved:

[0015] (1). In the washing device for flame retardant processing, by starting the circulation pump, the cleaning liquid in the filtering cylinder is pumped into the water delivery pipe through the circulation pipe and sprayed out from the nozzle.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides two technical solutions:

[0024] Figures 1-4 The first embodiment is shown: A washing device for flame retardant processing includes a washing tank 1. A plurality of fixing plates 4 are fixedly installed on the inner wall of the washing tank 1. A plurality of ultrasonic transducers 41 are installed on the outer surface of the fixing plates 4. A filtering mechanism 2 is arranged on the right side of the washing tank 1 for filtering the cleaning liquid. A circulation mechanism 3 is arranged outside the washing tank 1 for circulating the cleaning liquid. The ultrasonic transducer 41 converts the electrical signal generated by the generator into mechanical vibration. During use, the ultrasonic transducer 41 needs to be connected to the ultrasonic generator;

[0025] The circulation mechanism 3 includes a circulation pipe 32 and an overflow water tank 35. The overflow water tank 35 is fixedly installed at a position near the top of the outer surface of the washing tank 1. A plurality of water delivery pipes 33 are fixedly communicated with the outer wall of the circulation pipe 32 near the left side. The water delivery pipes 33 penetrate through the front surface of the washing tank 1 and extend into the interior. A plurality of spray heads 34 are fixedly communicated with the outer wall of the water delivery pipes 33. By starting the circulation pump 31, the cleaning liquid in the filter cartridge 21 is pumped into the water delivery pipes 33 through the circulation pipe 32 and sprayed out from the spray heads 34. Since the spray heads 34 are themselves in the cleaning liquid, the solvent sprayed out from the spray heads 34 will drive the surrounding liquid to surge, so that the flame retardant particles in the mesh material box 6 roll over. The rolling action enables all surfaces of the flame retardant particles to be fully exposed to the action of ultrasonic waves, avoiding the situation that some parts are always blocked and not cleaned properly.

[0026] A bracket 11 is fixedly installed at a position on the inner wall of the washing tank 1 above the ultrasonic transducer 41. A mesh material box 6 is placed on the top of the bracket 11. The bracket 11 can support the mesh material box 6, so that the mesh material box 6 is suspended in the washing tank 1 and the mesh material box 6 is higher than the washing tank 1, avoiding the leakage of flame retardant particles when the cleaning liquid in the washing tank 1 overflows.

[0027] Figures 1-4 The second embodiment is shown. The main difference from the first embodiment is that: the filtering mechanism 2 includes a filter cartridge 21. The filter cartridge 21 is communicated with the overflow water tank 35 through a connecting pipe 36. A filter element 22 is arranged at a position near the upper part inside the filter cartridge 21. A drain valve 23 is fixedly communicated with the outer wall of the filter cartridge 21 near the bottom. By arranging the filter element 22, impurities in the cleaning liquid can be filtered, so as to be recycled and reduce the cleaning cost. By opening the drain valve 23, it is convenient to drain and replace the cleaning liquid later.

[0028] A discharge pipe 25 is fixedly communicated with the outer wall of the filter cartridge 21 at a position above the filter element 22. The other end of the discharge pipe 25 is fixedly communicated with the bottom of the washing tank 1. A filter pump 24 is provided outside the discharge pipe 25. Through the filter pump 24, the cleaning liquid in the washing tank 1 can be pumped into the filter cartridge 21 through the discharge pipe 25, so as to filter the impurities precipitated in the washing tank 1.

[0029] A circulation pump 31 is provided outside the circulation pipe 32. The other end of the circulation pipe 32 is fixedly communicated with the outer wall of the filter cartridge 21 near the bottom. Through the circulation pump 31, the cleaning liquid in the filter cartridge 21 can be pumped into the washing tank 1 for circulation.

[0030] A plurality of honeycomb inclined plates 5 are arranged at a position on the inner wall of the washing tank 1 below the fixing plate 4. The honeycomb inclined plates 5 increase the precipitation area of impurities, thus accelerating the precipitation process.

[0031] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0032] During use, add cleaning liquid to the washing tank 1 until it is about to overflow, and then add about half of the cleaning liquid to the filter cartridge 21. After that, put the mesh material box 6 filled with flame retardant particles into the washing tank 1. At this time, the flame retardant particles in the mesh material box 6 completely enter the cleaning liquid. Then, use the ultrasonic transducer 41 to generate high-frequency acoustic wave vibrations to impact and remove the impurities on the surface and in the tiny pores of the flame retardant, so as to achieve the washing effect. At the same time, by starting the circulation pump 31, the cleaning liquid in the filter cartridge 21 is pumped through the circulation pipe 32 into the water delivery pipe 33 and sprayed out from the nozzle 34. Since the nozzle 34 is itself in the cleaning liquid, the solvent sprayed out from the nozzle 34 will drive the surrounding liquid to surge, so that the flame retardant particles in the mesh material box 6 tumble. The tumbling action makes all surfaces of the flame retardant particles fully exposed to the action of ultrasonic waves, avoiding the situation where some parts are always blocked and not cleaned properly. At the same time, ultrasonic cleaning can avoid damage to the structure of the flame retardant particles caused by high pressure. During the cleaning process, some impurities larger than the mass of the cleaning liquid sink to the bottom of the washing tank 1, while some impurities smaller than the mass of the cleaning liquid float upwards. And with the cleaning liquid continuously sprayed out from the nozzle 34, the water in the washing tank 1 overflows outwards and flows into the overflow tank 35, and enters the filter cartridge 21 through the connecting pipe 36, so as to circulate, making the cleaning liquid maintain a good purity during the cleaning process. When the cleaning of the flame retardant particles is completed, the cleaning liquid in the washing tank 1 is pumped through the discharge pipe 25 into the filter cartridge 21 by the filter pump 24, and is circulated and filtered in cooperation with the filter element 22 in the filter cartridge 21 and the circulation pump 31, so as to extend the service life of the cleaning liquid.
