Description

Technical Field

[0001] This utility model belongs to the field of construction and coating equipment technology, specifically an anti-clogging filtration mechanism that links a vibrating screen and a diaphragm pump. Background Technology

[0002] Building coatings emulsions are core raw materials in the field of architectural coatings. They are mainly used for the decoration and protection of building parts such as exterior walls, interior walls, waterproofing, and fireproofing. The main components include polymer emulsions, additives, fillers, and pigments. Common types include acrylic emulsions, styrene-acrylic emulsions (SAE), silicone-acrylic emulsions, pure acrylic emulsions, and elastic emulsions.

[0003] During the use of construction coating emulsion, a vibrating screen and a diaphragm pump need to be used in conjunction. The vibrating screen disperses the material through high-frequency vibration and separates large particles or agglomerates using the filter plate aperture to prevent them from entering the subsequent pipeline. The diaphragm pump generates negative pressure suction and positive pressure discharge through the reciprocating motion of the flexible diaphragm.

[0004] However, in actual use, when the vibrating screen and the diaphragm pump are used in conjunction, a filtration mechanism is required to filter the coating emulsion. Due to the lack of a corresponding cleaning mechanism, when the filter plate is clogged and the output is insufficient, the pressure inside the pump will drop, thereby affecting the normal output of the diaphragm pump and causing insufficient output. Utility Model Content

[0005] The purpose of this invention is to address the above problems by providing an anti-clogging filtration mechanism that links a vibrating screen with a diaphragm pump, which has the advantage of preventing filter plate clogging.

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

[0023] 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.

[0024] like Figures 1 to 6 As shown, this utility model provides an anti-clogging filter mechanism that links a vibrating screen and a diaphragm pump. It includes a housing 1, a screen plate 2 that is movably sleeved on the top of the housing 1, a scraper 3 that is movably connected to the middle of the top of the screen plate 2, the outside of the scraper 3 and the inside of the housing 1 that are movably sleeved, an inner round rod 4 that is fixedly installed on the middle of the bottom of the screen plate 2, an outer round rod 5 that is movably sleeved on the outside of the inner round rod 4, and a linkage block 6 that is fixedly installed on the bottom of the inner round rod 4 that is movably sleeved on the outside of the outer round rod 5.

[0025] A first spring 7 is fixedly installed at the bottom of the linkage block 6. The other end of the first spring 7 is fixedly connected to the bottom of the inner side of the outer round rod 5. A driven gear 8 is fixedly installed at the bottom of the outer round rod 5. A first motor 9 is fixedly installed at the bottom of the front side of the outer side of the housing 1. A first rotating shaft 10 is fixedly sleeved at the other end of the output shaft of the first motor 9. The rear end of the first rotating shaft 10 passes through the housing 1 and extends into the interior of the housing 1, and a driving gear 11 is fixedly sleeved thereon. The outer side of the driving gear 11 meshes with the outer side of the driven gear 8. When the first motor 9 is started, the first rotating shaft 10 will drive the driving gear 11 to rotate.

[0026] Since the driving gear 11 and the driven gear 8 are meshed, as the driving gear 11 rotates, the driven gear 8 will cause the outer round rod 5 to rotate. Since the linkage block 6 is movably sleeved inside the outer round rod 5 and the left and right sides of the linkage block 6 are two protrusions, the inner round rod 4 will cause the screen plate 2 to rotate along the inside of the box 1 under the drive of the linkage block 6. In this way, the scraper 3, which is movably connected to the top of the screen plate 2, can be used to clean the screen plate 2, thereby preventing the screen plate 2 from becoming blocked and causing insufficient output.

[0027] Among them, the top of the outer round rod 5 is movably sleeved with a limiting ring 12, and the outer side of the limiting ring 12 is fixedly installed with a first support rod 13. There are three first support rods 13, and the other ends of the three first support rods 13 are respectively fixedly connected to the inside of the box 1. The inside of the limiting ring 12 and the outside of the outer round rod 5 are both smooth, thus ensuring that the outer round rod 5 will not get stuck when it rotates along the inside of the limiting ring 12. At the same time, the cooperation between the limiting ring 12 and the first support rod 13 will play a supporting and limiting role for the outer round rod 5.

[0028] The outer bottom of the outer round rod 5 is movably sleeved with a protective shell 14. The inner front side of the protective shell 14 is movably sleeved with the outer side of the first rotating shaft 10. The rear side of the outer side of the protective shell 14 is fixedly installed with a second support rod 15. The other end of the second support rod 15 is fixedly connected to the inside of the housing 1. The presence of the second support rod 15 will support and fix the protective shell 14. The presence of the protective shell 14 will protect the driven gear 8 and the driving gear 11, thereby ensuring that the driven gear 8 and the driving gear 11 are not affected by the coating emulsion.

[0029] A second motor 16 is fixedly installed on the upper left side of the front of the outer side of the housing 1. A second rotating shaft 17 is fixedly sleeved on the other end of the output shaft of the second motor 16. The rear end of the second rotating shaft 17 passes through the housing 1 and extends to the outside of the housing 1. An elliptical block 18 is fixedly sleeved on the middle of the outer side of the second rotating shaft 17. The top of the outer side of the elliptical block 18 is movably connected to the bottom end of the sieve plate 2. When the second motor 16 is started, the second rotating shaft 17 will drive the elliptical block 18 to rotate. Since the top of the outer side of the elliptical block 18 is movably connected to the bottom end of the sieve plate 2, the sieve plate 2 will vibrate as the elliptical block 18 rotates.

[0030] A long rod 19 is fixedly installed at the middle of the top of the scraper 3. A column 20 is movably sleeved on the top of the long rod 19. The top of the column 20 is fixedly sleeved on the inside of the middle of the top of the box 1. A slider 21 is movably sleeved on the bottom of the inside of the column 20. The bottom end of the slider 21 is fixedly connected to the top of the long rod 19. When the screen plate 2 vibrates, since the long rod 19 and the slider 21 are movably sleeved inside the column 20, when the screen plate 2 moves upward, the scraper 3 will move upward along with the long rod 19 and the slider 21, thus ensuring that the scraper 3 will not affect the vibration of the screen plate 2.

[0031] A limiting rod 22 is fixedly installed at the middle of the top of the slider 21. The top of the limiting rod 22 passes through the column 20 and extends to the outside of the column 20. A second spring 23 located outside the limiting rod 22 is fixedly installed at the top of the slider 21. The other end of the second spring 23 is fixedly connected to the top of the inside of the column 20. When the second spring 23 is in a compressed state, under the restoring action of the second spring 23, the slider 21 will be forced to move downward with the long rod 19 and the scraper 3, thereby ensuring that the scraper 3 and the screen plate 2 are always in contact. The presence of the limiting rod 22 can limit the slider 21 and prevent the scraper 3, the long rod 19 and the slider 21 from rotating with the screen plate 2.

[0032] A feed pipe 24 is fixedly connected to the left side of the top of the box 1, and a diaphragm pump 25 is fixedly installed at the bottom of the box 1. The presence of the feed pipe 24 will facilitate the feeding of the coating emulsion, while the presence of the diaphragm pump 25 will facilitate the discharge of the coating emulsion that has been filtered inside the box 1.

[0033] Working principle and usage process of this utility model:

[0034] In use, the operator starts the second motor 16, causing the second rotating shaft 17 to drive the elliptical block 18 to rotate. This causes the elliptical block 18 to exert a pushing force on the sieve plate 2, pushing the sieve plate 2, along with the inner round rod 4 and the linkage block 6, to move upward along the inside of the outer round rod 5 and stretch the first spring 7. Under the restoring action of the first spring 7, when the elliptical block 18 no longer pushes the sieve plate 2, the linkage block 6 will reset the inner round rod 4 and the sieve plate 2. This cycle is repeated to achieve the vibration of the sieve plate 2. Then, the operator can input the coating emulsion into the housing 1 through the feed pipe 24, so that the coating emulsion is discharged through the diaphragm pump 25 after being filtered by the sieve plate 2.

[0035] When the screen plate 2 becomes clogged, the operator starts the first motor 9, causing the first rotating shaft 10 to drive the drive gear 11 to rotate. This causes the driven gear 8, which meshes with the drive gear 11, to rotate along the inside of the limiting ring 12 and the protective shell 14, along with the outer rod 5. Consequently, the linkage block 6 rotates along with the screen plate 2 via the inner rod 4. Simultaneously, since the second spring 23 is in a compressed state, the slider 21 will be subjected to a downward force under the restoring action of the second spring 23. This forces the slider 21, along with the long rod 19 and the scraper 3, to move towards the screen plate 2, thus ensuring that the scraper 3 and the screen plate 2 remain in contact with each other. In this way, the rotation of the scraper 3 and the screen plate 2 can be used to clean the screen plate 2, preventing the screen plate 2 from becoming clogged and causing insufficient output.
