Description

Technical Field

[0001] The present application relates to the technical field of flocculant preparation, and particularly to a feeding device for preparing an environmentally friendly paint mist flocculant. Background Art

[0002] Paint mist coagulants are mainly used to capture and agglomerate paint mist particles suspended in the air, converting them from a gaseous state to a solid state for subsequent collection and treatment. When the air in a spray booth contains a large amount of paint mist, spraying a paint mist coagulant can break the surface tension of the paint mist, causing tiny paint droplets to aggregate into larger particles. These large particles are more likely to settle under the action of gravity, thereby reducing blockage of the filtration system and extending the service life of the filter material. In the patent document with the publication number "CN112607837B", there is disclosed "a high-efficiency paint mist flocculant and its preparation method, including Agent A and Agent B; by weight, Agent A includes the following components: 1000 parts of water; 40 - 55 parts of quaternized hydroxyethyl cellulose (powder); 80 - 120 parts of aluminum sulfate (crystalline); 6 - 12 parts of dodecyl trimethyl ammonium chloride (liquid or gel); 5 - 8 parts of ferric citrate (crystalline powder); 3 - 5 parts of coconut oil diethanolamide; 2 - 3 parts of κ-carrageenan; 2 - 3 parts of alkylphenol polyoxyethylene ether; 0.5 - 0.8 parts of dihydroflavonoid glycoside; 3 - 10 parts of sodium sulfosuccinate monoester; by weight, Agent B includes the following components: 1000 parts of water; 0.3 - 0.6 parts of sodium polyacrylate; 1 - 2 parts of alkylphenol polyoxyethylene ether; when the high-efficiency paint mist flocculant is used, the water body containing paint mist first contacts Agent A and then contacts Agent B".

[0003] Among the raw materials for preparing this paint mist flocculant, there are substances such as liquids, powders, and crystals. During the production process, various raw materials need to be put into a solvent in a fixed proportion. The weighed raw materials are directly put into water through a pipeline. Solid and liquid solutes are usually less affected by the water solvent, while powder raw materials are easily affected by moisture and adhere at the feeding port position, resulting in poor discharge. At the same time, it will also cause inaccurate input ratios of the raw materials, leading to a decline in the performance of the flocculant. Therefore, to solve the above problems, the present application provides a feeding device for preparing an environmentally friendly paint mist flocculant. Utility Model Content

[0004] In order to solve the problem that the existing powder feeding mechanism is prone to adhesion, resulting in limited discharge, the present application provides a feeding device for preparing an environmentally friendly paint mist flocculant.

[0005] An environmentally friendly paint mist flocculant preparation feeding device provided by the present application includes a water pipe and a material cylinder arranged above the water pipe. The bottom end of the material cylinder is communicated with the water pipe through a rotary joint. A conveying assembly is movably arranged inside the rotary joint. The conveying assembly includes a feeding screw slidably embedded inside the rotary joint and a sliding rod welded to the top end of the feeding screw. A radial driving member and an axial driving member are arranged above the conveying assembly, so that the feeding screw can protrude into the water pipe at the end of the rotary joint while rotating.

[0006] Preferably, the radial driving member is a motor, and the output end of the motor is fixedly connected to the sliding rod through a coupling.

[0007] Preferably, the axial driving member is a cylinder fixedly connected to the radial driving member. A bracket for fixing the position of the cylinder is welded on the outer wall of the material cylinder. When the cylinder extends, the feeding screw extends into the water pipe.

[0009] Preferably, the upper section of the rotary joint extends upward, and its length is the same as that of the feeding screw. A plurality of material leakage holes are annularly arranged at the position of the bottom end of the rotary joint in the material cylinder.

[0010] Preferably, a weighing plate is slidably sleeved outside the rotary joint inside the material cylinder. A plurality of support blocks are welded on the inner wall of the material cylinder, and a pressure sensor that fits with the bottom of the weighing plate is arranged on the support blocks.

[0011] Preferably, a material discharging hole is formed on the weighing plate, and a push rod that cooperates with the material discharging hole is slidably attached to the weighing plate.

[0012] Preferably, a limiting strip is welded on the outer wall of the sliding rod, and a collar is slidably sleeved on the sliding rod. A limiting groove that cooperates with the limiting strip is arranged on the collar. The collar is welded to the push rod through a connecting piece.

Detailed Description of the Embodiments

[0022] The following will Figure 1 - Figure 5 further describe the present application in detail.

[0023] Embodiment 1:

[0024] A feeding device for preparing an environmentally friendly paint mist flocculant, referring to Figure 1 - Figure 5 , includes a water pipe 1 and a barrel 2 arranged above the water pipe 1. The water pipe 1 is arranged at an inclination of 30°, so that the water flow can flow by relying on the gravitational potential energy. A plurality of barrels 2 are evenly distributed on the water pipe 1, and different types of raw materials can be placed in each barrel 2. The bottom end of the barrel 2 is communicatively connected to the water pipe 1 through an adapter pipe 3. A conveying assembly 8 is movably arranged inside the adapter pipe 3. The conveying assembly 8 includes a feeding screw 81 slidably embedded inside the adapter pipe 3 and a sliding rod 82 welded to the top end of the feeding screw 81. A radial driving member and an axial driving member are arranged above the conveying assembly 8, so that the feeding screw 81 can protrude from the end of the adapter pipe 3 into the water pipe 1 while rotating.

[0025] The radial driving member is a motor 4. The output end of the motor 4 is fixedly connected to a slide rod 82 through a coupling 7. The axial driving member is a cylinder 6 fixedly connected to the radial driving member. A bracket 5 for fixing the position of the cylinder 6 is welded on the outer wall of the barrel 2. When the cylinder 6 extends, the feeding screw 81 extends into the water pipe 1. The air source of the cylinder 6 comes from the air source system in the factory, and the expansion and contraction of the cylinder 6 is controlled through structures such as a solenoid valve. When the cylinder 6 extends, the end of the feeding screw 81 enters the water pipe 1 and is washed by the water flow to reduce the amount of adhesion. The rotation of the feeding screw 81 acts on the inner wall of the adapter pipe 3, and the raw materials adhered to the inner wall can be pushed downward.

[0026] A protruding section 31 is integrally formed at the bottom end of the adapter pipe 3, and the protruding section 31 is located inside the water pipe 1. The function of the protruding section 31 is that the raw materials adhered to the protruding section 31 can be directly washed because they can be in direct contact with the water flow inside the water pipe 1, so as to avoid adhesion between the raw materials and the end of the adapter pipe 3. The upper section of the adapter pipe 3 extends upward, and its length is the same as that of the feeding screw 81. A plurality of leakage holes 32 are formed in an annular array at the bottom end position of the adapter pipe 3 located in the barrel 2.

[0027] A weighing plate 9 is sleeved on the outside of the adapter pipe 3 located inside the barrel 2. A plurality of support blocks 11 are welded on the inner wall of the barrel 2, and a pressure sensor 12 that fits with the bottom of the weighing plate 9 is arranged on the support blocks 11. When the raw materials are transported to the weighing plate 9 through an external pipeline, the weighing plate 9 acts on the pressure sensor 12, so as to control the amount of transported raw materials and ensure the accuracy of the feeding amount. Before each weighing, the weighing system is reset to ensure that the weighed weight is the net weight of the raw materials. A blanking hole 91 is formed in the weighing plate 9, and a push rod 10 that cooperates with the blanking hole 91 is slidably connected to the weighing plate 9 in a fitting manner. The push rod 10 rotates around the axis of the feeding screw 81 to push the raw materials through the blanking hole 91 into the barrel 2. The side view of the push rod 10 has a structure that is narrower at the top and wider at the bottom to reduce the possibility of raw materials accumulating on it. The position of the blanking hole 91 deviates from the position of the raw material feeding pipeline, further reducing the possibility of raw materials accumulating on the push rod 10. The deviation position should not be too far. While reducing the influence, it should be as close as possible to the feeding pipeline position to reduce the amount of materials remaining on the weighing plate 9 during the pushing process. Preferably, the weighing plate 9 does not fit with the inner wall of the barrel 2, and there is a gap between them. The length of the push rod 10 is greater than the outside of the weighing plate 9, so that when the push rod 10 rotates, even the materials that do not enter the blanking hole 91 will fall from the edge of the weighing plate 9 into the barrel 2 under the action of centrifugal force.

[0028] A limiting strip 821 is welded on the outer wall of the sliding rod 82, and a collar 1002 is sleeved on the sliding rod 82. A limiting groove 1003 that cooperates with the limiting strip 821 is provided on the collar 1002. The collar 1002 is welded to the push rod 10 through a connecting piece 1001. The height of the sliding rod 82 is greater than the thickness of the collar 1002. The height of the sliding rod 82 is equal to the stroke distance of the air cylinder 6. The height of the sliding rod 82 is greater than the thickness of the collar 1002. When the air cylinder 6 pushes the conveying assembly 8 as a whole to perform an axial displacement, the collar 1002 can slide on it, so as to ensure that the overall position of the push rod 10 does not change. The feeding screw 81 performs an axial position. The limiting strip 821 and the limiting groove 1003 cause the push rod 10 to rotate with the rotation of the feeding screw 81, ensuring the pushing of the material.

[0029] The raw materials pushed into the barrel 2 will enter the adapter pipe 3 through the leakage holes 32 and be pushed downward into the water pipe 1 under the action of the feeding screw 81, thus completing the batching operation.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
