Description

Technical Field

[0001] The utility model relates to the technical field of building material filtration, in particular to a filtering and drying device for raw materials of architectural coatings. Background Art

[0002] The material that can be well bonded to the substrate material and form a complete and tough protective film when coated on the surface of an object is called an architectural coating. Coating and paint are the same concept. Paint is a long-established customary name. Since it was introduced into China, it has been used in the construction industry. The functions of coatings can be summarized into three aspects: protective function, decorative function, and special functional function. The general composition of coatings includes film-forming substances, pigments and fillers, solvents, and additives. Coatings are one of the indispensable materials for the development of the national economy. Due to the many special functions of coatings, there are a wide variety of coating varieties. When producing coatings, in order to make the coatings uniform and delicate, the raw materials need to be screened and filtered.

[0003] The Chinese utility model patent (CN220177531U) provides a dry powder filtering device for coating processing raw materials, including a dry powder filtering machine box, a dry powder residue collector, and a dry powder filtering component. The dry powder residue collector is rotatably installed at the center inside the dry powder filtering machine box, and the dry powder filtering component is fixedly installed on the dry powder residue collector. A number of dry powder filtering components are fixedly installed at equal intervals on the inner wall of the dry powder filtering machine box. It quickly screens and filters the dry powder by scraping. The disadvantage is that this device cannot dry the raw materials. If there is moisture in the air, the raw materials will adhere to the filter screen, affecting the filtering effect. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a filtering and drying device for raw materials of architectural coatings, which can dry the raw materials during filtration and has high filtration efficiency.

[0005] To solve the above technical problem, the technical solution adopted by the utility model is to provide a filtering and drying device for raw materials of architectural coatings, including a frame and a raw material cylinder inclined to the ground and arranged on the frame; the raw material cylinder includes a heating cylinder and a filtering cylinder; a filter screen is provided on the cylinder wall of the filtering cylinder, the heating cylinder is coaxially sleeved outside the filtering cylinder, and a heating chamber is arranged between the heating cylinder and the filtering cylinder; a stirring rod coaxial with the filtering cylinder is arranged inside the filtering cylinder, spiral blades are arranged on the stirring rod, and one end of the stirring rod is connected to a driving motor;

[0006] It further includes a driving device, which is arranged at one end of the filtering cylinder and is used to drive the filtering cylinder to rotate inside the heating cylinder.

[0007] Furthermore, a discharge port is arranged at one end of the heating cylinder close to the ground, and a discharge valve is arranged on the discharge port.

[0008] Furthermore, it also includes an air intake pipe and an exhaust pipe, which are respectively arranged at two ends of the heating tube on a side away from the ground.

[0009] Furthermore, the air inlet pipe and the exhaust pipe are provided with dustproof nets.

[0010] Furthermore, it also includes a rolling ring, grooves are provided at both ends of the filter cylinder, and the inner surface of the rolling ring is slidably connected to the inner wall of the groove; the inner wall of the heating cylinder is provided with a slide groove adapted to the rolling ring, and the outer surface of the rolling ring is slidably connected to the inner wall of the slide groove.

[0011] Furthermore, the raw material barrel has an inclination angle of 10 to 20 degrees with the ground.

[0012] The beneficial effect of the utility model is that after the raw material enters the filter cylinder, the filter cylinder starts to rotate, and the raw material is filtered by the filter screen on the filter cylinder and then falls into the heating cylinder. At the same time, the stirring rod rotates, and the spiral blades on the stirring rod stir and break up the raw material, thereby improving the filtering efficiency. Since the filter cylinder is inclined with the ground, the filtered waste residue is discharged from the filter cylinder under the action of gravity, and the rotation of the spiral blades can also push the waste residue to be discharged. During the filtering process, the heating chamber heats the raw material to play a drying role. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0018] See also Figure 1-2A building paint raw material filtering and drying device comprises a frame 1, a raw material barrel 2 arranged on the frame 1 and inclined to the ground; the raw material barrel 2 comprises a heating barrel 21 and a filter barrel 22; a filter screen 221 is arranged on the barrel wall of the filter barrel 22, the heating barrel 21 is coaxially sleeved on the outside of the filter barrel 22, and a heating chamber 3 is arranged between the heating barrel 21 and the filter barrel 22; a stirring rod 222 coaxial with the filter barrel 22 is arranged in the filter barrel 22, a spiral blade 2221 is arranged on the stirring rod 222, and one end of the stirring rod 222 is connected to a driving motor 2222;

[0019] The heating tube 21 further comprises a driving device 4 , which is disposed at one end of the filter cartridge 22 and is used to drive the filter cartridge 22 to rotate inside the heating cartridge 21 .

[0020] As can be seen from the above description, after the raw material enters the filter cylinder 22, the filter cylinder 22 starts to rotate, and the raw material is filtered by the filter screen 221 on the filter cylinder 22 and then falls into the heating cylinder 21. At the same time, the stirring rod 222 rotates, and the spiral blade 2221 on the stirring rod 222 stirs and breaks up the raw material to improve the filtering efficiency. Since the filter cylinder 22 is inclined with the ground, the filtered waste residue is discharged from the filter cylinder 22 under the action of gravity, and the rotation of the spiral blade 2221 can also push the waste residue to be discharged. During the filtering process, the heating chamber 3 heats the raw material to play a drying role.

[0021] Furthermore, the heating cylinder 21 is provided with a discharge port 211 at one end close to the ground, and the discharge port 211 is provided with a discharge valve 2111 .

[0022] As can be seen from the above description, the discharge port 211 can discharge the filtered raw materials.

[0023] Furthermore, it also includes an air intake pipe 212 and an exhaust pipe 213, which are respectively arranged at two ends of the heating tube 21 on the side away from the ground.

[0024] As can be seen from the above description, the hot air enters from the air inlet pipe 212 and is discharged from the exhaust pipe 213 to complete the circulation, thereby heating the raw materials in the heating cylinder 21 .

[0025] Furthermore, dustproof nets 2131 are provided on the air inlet pipe 212 and the air outlet pipe 213 .

[0026] As can be seen from the above description, the filtered raw materials are prevented from clogging the air inlet pipe 212 or the air outlet pipe 213 .

[0027] Furthermore, it also includes a rolling ring 223, and grooves 224 are provided at both ends of the filter cylinder 22, and the inner surface of the rolling ring 223 is slidably connected to the inner wall of the groove 224; the inner wall of the heating cylinder 21 is provided with a slide groove 214 adapted to the rolling ring 223, and the outer surface of the rolling ring 223 is slidably connected to the inner wall of the slide groove 214.

[0028] As can be seen from the above description, the rolling ring 223, the groove 224 and the slide groove 214 cooperate with each other, so that the filter cylinder 22 can rotate in the heating cylinder 21. At the same time, the airtightness of the heating cylinder 21 is ensured, and the heating effect is improved.

[0029] Furthermore, the raw material barrel 2 has an inclination angle of 10 to 20 degrees with the ground.

[0030] As can be seen from the above description, the waste residue needs to be discharged from the filter cartridge 22 under the action of gravity, and the filter cartridge 22 needs to have a certain inclination angle with the ground. However, it should not be too large, because too large an inclination angle will cause the raw materials to be discharged too quickly and directly, and the filtering effect cannot be achieved.

[0031] Embodiment 1:

[0032] Application scenario: In order to make the paint uniform and fine when producing paint, the raw materials need to be screened and filtered. However, sometimes the raw materials themselves contain moisture and are easy to stick to the screen, causing the screen to be blocked and the filtration efficiency is low.

[0033] like Figure 1-2 A building paint raw material filtering and drying device comprises a frame 1, a raw material barrel 2 arranged on the frame 1 and inclined to the ground; the raw material barrel 2 comprises a heating barrel 21 and a filter barrel 22 (the filter barrel 22 has openings at both ends, the higher end is a feed port, and the other end is a discharge port); a filter screen 221 is arranged on the barrel wall of the filter barrel 22, the heating barrel 21 is coaxially sleeved on the outer side of the filter barrel 22, and a heating chamber 3 is arranged between the heating barrel 21 and the filter barrel 22; a stirring rod 222 coaxial with the filter barrel 22 is arranged in the filter barrel 22, a spiral blade 2221 is arranged on the stirring rod 222, and one end of the stirring rod 222 is connected to a driving motor 2222;

[0034] It also includes a driving device 4 (which can be driven by a pulley or a motor), which is arranged at one end of the filter cylinder 22 and is used to drive the filter cylinder 22 to rotate inside the heating cylinder 21. The heating cylinder 21 is provided with a discharge port 211 at one end close to the ground, and a discharge valve 2111 is provided on the discharge port 211. It also includes a rolling ring 223, and grooves 224 are provided at both ends of the filter cylinder 22, and the inner surface of the rolling ring 223 is slidably connected to the inner wall of the groove 224; the inner wall of the heating cylinder 21 is provided with a slide 214 adapted to the rolling ring 223, and the outer surface of the rolling ring 223 is slidably connected to the inner wall of the slide 214. It also includes an air inlet pipe 212 and an exhaust pipe 213, which are respectively arranged at both ends of the heating cylinder 21 away from the ground (heating is carried out by a hot air dryer, and the air inlet pipe 212 and the air outlet pipe are connected to the hot air dryer to form a hot air circuit).

[0035] Working principle of the above-mentioned building coating raw material filtering and drying device: When in use, pour the raw materials into the filtering cylinder 22. The motor drives the belt pulley to make the filtering cylinder 22 rotate. The high-speed rotation enables the raw materials to be filtered more quickly by the filter screen 221 on the filtering cylinder 22, and then fall into the heating cylinder 21. At the same time, the stirring rod 222 rotates, and the spiral blades 2221 on the stirring rod 222 stir and disperse the raw materials to improve the filtering efficiency. The rotation of the filtering cylinder 22 and the rotation of the spiral blades 2221 can prevent the raw materials from blocking the filter holes of the filter screen 221; Since the filtering cylinder 22 is inclined with respect to the ground, the filtered waste residue is discharged from the filtering cylinder 22 under the action of gravity. At the same time, the rotation of the spiral blades 2221 can also push the waste residue out. (The reverse rotation of the spiral blades 2221 can be controlled to delay the discharge time of the waste residue to achieve the effect of fine processing) During the filtering process, the heating cavity 3 heats the raw materials to play a drying role and prevent the raw materials from being damp and sticking to the filter screen 221.

[0036] In summary, the present invention provides a building coating raw material filtering and drying device, which can dry the raw materials during filtering and has a high filtering efficiency.

[0037] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical fields, shall be equally included in the patent protection scope of the present invention.
