Description

A filtration device for fire-retardant coating production Technical Field

[0001] This invention belongs to the technical field of fire-retardant coating production equipment, and in particular relates to a filtration device for fire-retardant coating production. Background Technology

[0002] Fire-retardant coatings are applied to the surface of flammable materials to improve their fire resistance, slow the spread of flames, or prevent combustion for a certain period of time. They are also called flame-retardant coatings. They are applied to the surface of combustible substrates to alter the material's surface combustion characteristics and inhibit the rapid spread of fire; or applied to building components to improve their fire resistance.

[0003] Filtration is an important step in the production of fire-retardant coatings. To remove impurities present in the coating production process, filtration equipment is needed to filter the coating. When traditional filtration equipment filters fire-retardant coatings, iron filings smaller than the filter mesh size cannot be intercepted. After the iron filings are mixed into the coating, they will affect the fire resistance of the coating. At the same time, iron filings larger than the filter mesh size accumulate on the filter mesh, which not only easily clogs the filter mesh, but also easily damages the filter mesh over time. Summary of the Invention

[0006] Furthermore, the inner top side of the conical plate is connected to a support column, and the bottom end of the support column is connected to a crossbar; the inner wall of the tube is provided with a protrusion, the upper surface of the protrusion is set as an inclined surface, and a slot for the crossbar to be inserted is opened on the protrusion. The crossbar is inserted into the slot of the protrusion to fix the position of the conical plate, prevent vibration and displacement, and facilitate the installation and disassembly of the conical plate.

[0007] Furthermore, the support includes a support plate, with at least three support legs connected to the bottom side of the support plate. The filtering mechanism is installed inside the support, and the feeding mechanism is installed on the upper surface of the support plate.

[0009] Furthermore, the mounting block and the support ring are respectively provided with protruding post A and protruding post B in the shape of a frustum or a cone, and the provision of protruding post A and protruding post B ensures that the spring is accurately aligned.

[0010] Furthermore, a convex ring is provided on the outer periphery of the pipe body, and two guide telescopic component assemblies are connected between the convex ring and the support plate.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0020] Please refer to Figures 1, 3, and 5-6. This invention is a filtration device for fire-retardant coating production, including a support frame, a filtration mechanism 3 and a feeding mechanism 2 mounted on the support frame. The feeding mechanism 2 is located above the filtration mechanism 3. During use, the coating is transported into the filtration mechanism 3 for filtration. In the fire-retardant coating production process, iron filings are easily mixed into the coating. Based on this, the feeding mechanism 2 provided by this invention includes a tube body 20. A cover plate 200 is detachably installed at the top of the tube body 20. An opening B201 is opened in the middle of the cover plate 200, and an inlet pipe 21 is installed on the opening B201. A conical plate 27 is installed on the inner wall of the tube body 20 directly below the inlet pipe 21. The top of the conical plate 27 is directly opposite the bottom of the inlet pipe 21. Several magnetic retaining rings 271 are provided on the upper surface of the conical plate 27. The fire-retardant coating impacts the conical plate 27 through the inlet pipe 21, and the magnetic retaining rings 271 adsorb the iron filings, allowing the coarse material to enter the filtration mechanism 3.

[0021] Specifically, in order to facilitate the cleaning of the adsorbed iron filings during use, the conical plate 27 needs to be removed from the tube body 20. That is, in order to facilitate the installation and disassembly of the conical plate 27 inside the tube body 20, a support column 28 is connected to the inner top side of the conical plate 27, and a crossbar 29 is connected to the bottom end of the support column 28. The inner wall of the tube body 20 is provided with a protrusion 203, the upper surface of the protrusion 203 is set as an inclined surface, and a slot 204 for the crossbar 29 to be inserted is opened on the protrusion 203.

[0022] Specifically, in actual production, as shown in Figure 1, the support includes a support plate 1, with four support legs 11 connected to the bottom side of the support plate 1, and the support legs 11 are fixed on the vibrating table. The feeding mechanism 2 is installed on the upper surface of the support plate 1. The filtering mechanism 3 includes a housing 30, which has a tubular structure. The bottom end of the housing 30 is connected to a housing 31 whose diameter gradually decreases from top to bottom. A filter screen 32 is installed inside the housing 30. A mounting block 35 is installed on the outer bottom side of the housing 31. A mounting frame 12 is connected between the four support legs 11. A support ring 13 is fixed on the mounting frame 12. A spring 14 is connected between the mounting block 35 and the support ring 13. The spring 14 facilitates the filtering mechanism 3 installed on the vibrating table to vibrate up and down for filtering under the action of the vibrating table.

[0023] Based on the above, in order to facilitate the coating material in the feeding mechanism 2 falling into the filtering mechanism 3, an opening A10 is provided at the center of the support plate 1. A protruding tube 101 is provided on the bottom side of the support plate 1 at the opening A10. The opening A10 and the tube body 20 are concentric. The inner wall of the tube body 20 is provided with a guide section 202 whose diameter gradually decreases from top to bottom. The bottom diameter of the guide section 202 is smaller than the diameter of the opening A10, and the shell 30 is sleeved on the outer periphery of the protruding tube 101. An ultrasonic transducer is embedded in the inner wall of the guide section 202. After being powered on, the amplitude is 5-10μm. The transducer operates intermittently for 5 seconds and then stops for 5 seconds.

[0024] The housing 31 is connected to a discharge pipe A34 and a discharge pipe B33. The inlet end of the discharge pipe A34 is higher than the inlet end of the discharge pipe B33. When using the discharge pipe A34 for normal filtration, the material is discharged through the discharge pipe A34. When the machine is stopped to clean the filter screen 32, the material is discharged through the discharge pipe B33.

[0025] Based on the above, as shown in Figure 4, convex pillars A351 and B131 in the shape of a frustum are respectively provided on the mounting block 35 and the support ring 13, and the two ends of the spring 14 are respectively installed on the periphery of the convex pillars A351 and B131.

[0026] To accommodate coatings of different viscosities, as shown in Figure 2, a convex ring 22 is provided on the outer periphery of the tube body 20. Two guide telescopic component assemblies and several elastic telescopic components 23 are connected between the convex ring 22 and the support plate 1. The guide telescopic component assembly includes two guide telescopic components 24, each of which includes a guide sleeve A and a guide post that cooperate with each other. The guide sleeve A and the guide post are respectively connected to the convex ring 22 and the support plate 1. A pin hole A is provided on the guide sleeve, and several pin holes B are provided on the guide post. During use, the relative positions of the guide sleeve A and the guide post are locked by the pin assembly, which means that the gap width formed between the bottom end of the tube body 20 and the conical plate 27 is adjusted.

[0027] Specifically, in order to facilitate locking the relative position of the guide sleeve A and the guide post, a pin assembly is also provided, as shown in Figure 2. The pin assembly includes two guide sleeves B25 that are fixed parallel to each other on the upper surface of the support plate 1. A U-shaped frame 26 is inserted into the ends of the two guide sleeves B25. The two U-shaped frames 26 are symmetrically arranged, and a pin 261 that passes through pin holes A and B is provided on the inner side of the U-shaped frame 26. The two ends of the U-shaped frame 26 are respectively inserted into the guide sleeves B25.

[0028] Based on the above, as shown in Figure 7, two retaining rings 251 with a gap are provided in the middle of the guide sleeve B25. The ends of the two U-shaped frames 26 located in the same guide sleeve B25 are respectively provided with protrusions 261. The ends of the two protrusions 261 are respectively provided with magnetic blocks A262 and B263 that attract each other. After the ends of the two U-shaped frames 26 are controlled to abut against the retaining rings 251, the magnetic blocks A262 and B263 attract each other.
