Description

Technical Field

[0001] This utility model relates to the field of feed mixers, and in particular to an atomizing oil spraying system for a horizontal twin-shaft paddle mixer. Background Technology

[0002] Horizontal twin-shaft paddle mixers are widely used mixing equipment in industries such as feed, food, and chemicals. They achieve efficient mixing of materials through paddles that rotate in opposite directions on two shafts. During the mixing process, liquid oils are often added to improve the characteristics of the materials (such as improving palatability, reducing dust, or enhancing the adhesion of nutrients).

[0003] A search revealed that utility model patent CN217140267U specifically discloses an oil spraying system for a feed mixer, comprising an oil storage tank, a first oil inlet pump, a weighing tank, a buffer tank, a second oil inlet pump, an oil spraying main pipe, several oil spraying branch pipes, an aeration device, and a mixer. The outlet of the oil storage tank is connected to the inlet of the first oil inlet pump, the outlet of the first oil inlet pump is connected to the inlet of the weighing tank, the outlet of the weighing tank is connected to the inlet of the buffer tank, the outlet of the buffer tank is connected to the inlet of the second oil inlet pump, and the outlet of the second oil inlet pump is connected to the input end of the oil spraying main pipe. An aeration port connected to the aeration device is provided on the oil spraying main pipe. Several oil spraying branch pipes are arranged in a row and installed on the upper side wall of the mixer, and each oil spraying branch pipe has a nozzle installed at its output end.

[0004] However, in actual use, since the feed inlet of the twin-shaft paddle mixer is usually located at the top, and the oil spray pipe usually spans the top of the mixing chamber, it is easily deformed by large pieces of material during feeding, and may even block the nozzle. When the external ambient temperature changes, it can easily cause fluctuations in the viscosity of the oil in the oil storage tank and pipeline, resulting in unstable atomization effect, and even the phenomenon of oil solidification and pipeline blockage.

[0025] Example 1

[0026] See Figures 1 to 4This utility model provides a horizontal dual-shaft paddle mixer atomizing oil spraying system, including a dual-shaft paddle mixer 1. The dual-shaft paddle mixer 1 includes a housing 2, the top of the housing 2 is a feed inlet, and a mixing chamber is provided inside the housing 2. A stirring paddle 3 is provided in both mixing chambers. Two sliding rods 4 are fixedly provided inside the housing 2 located at the upper part of the mixing chamber. A slider 5 is slidably provided on each sliding rod 4. An oil pipe 6 is fixedly provided on the two sliders 5. Two rows of atomizing nozzles 7 are provided on the oil pipe 6. Each row of atomizing nozzles 7 is directed towards one of the stirring paddles 3.

[0027] One end of the oil pipe 6 is connected to a hose, which is connected to an oil storage tank. An oil pump is also installed on the hose.

[0028] When grease needs to be added to the twin-shaft paddle mixer 1, the oil pump starts working and delivers the grease in the oil storage tank to the oil pipe 6 through the hose.

[0029] The grease in the oil pipe 6 is atomized into oil mist through two rows of atomizing nozzles 7 and sprayed onto the working area of ​​the corresponding stirring blade 3. The oil mist is spread by the high-speed rotating stirring blade 3 and mixed evenly with the material.

[0030] By setting two rows of atomizing nozzles 7 corresponding to the stirring blades 3, the oil mist is sprayed directly onto the high-speed rotating stirring component, and the oil mist diffusion is enhanced by the rotational kinetic energy of the blades, which significantly improves the uniformity of oil distribution.

[0031] The projections of the two rows of atomizing nozzles 7 on the horizontal plane are alternately arranged, and the distance between two adjacent atomizing nozzles 7 in the same row is 20-35cm.

[0032] By using the staggered arrangement of two rows of atomizing nozzles 7 on the horizontal projection surface, complementary spraying areas are formed, eliminating the coverage blind spots caused by the spacing of a single row of nozzles, and ensuring that the grease is evenly distributed on the cross-section of the mixing chamber.

[0033] Limiting the spacing between adjacent atomizing nozzles 7 in the same row to 20-35cm can avoid the waste of oil mist due to excessive spacing, and also prevent insufficient coverage due to excessive spacing. This allows the oil mist to diffuse to the blade action area at a reasonable density, enhancing the contact efficiency with the material.

[0034] Each sliding rod 4 is also slidably provided with a transition block 8, and two intermediate connecting rods 9 are rotatably provided on the transition block 8. Each intermediate connecting rod 9 is fixedly provided with a gear, and the gears are coaxial with the rotation axis of the intermediate connecting rod 9, and the two gears mesh with each other.

[0035] Each slider 5 is rotatably equipped with a driven link 10, and the movable end of the driven link 10 is rotatably connected to the movable end of an adjacent intermediate link 9.

[0036] A rotating shaft 11 is rotatably installed inside the housing 2 located at the upper part of the mixing chamber. Two active connecting rods 12 are fixedly installed on the rotating shaft 11. The movable end of each active connecting rod 12 is rotatably connected to the movable end of an adjacent intermediate connecting rod 9.

[0037] A swing arm 13 is fixedly installed at one end of the rotating shaft 11, and the swing arm 13 is located on the outside of the housing 2;

[0038] The housing 2 is also provided with a push rod 14, the fixed part of the push rod 14 is rotatably connected to the housing 2, and the telescopic part is rotatably connected to the movable end of the swing arm 13.

[0039] Since the upper middle part of the housing 2 is provided with a feeding port, when material is added through the feeding port at the top of the housing 2, the push rod 14 is activated to retract, the push rod 14 drives the swing arm 13 to rotate around the rotating shaft 11, and the swing arm 13 drives the active connecting rod 12 to swing.

[0040] The active connecting rod 12 transmits power through the intermediate connecting rod 9 meshing with the gear. The two meshing gears rotate synchronously in opposite directions, driving the intermediate connecting rods 9 on both sides to deflect synchronously in opposite directions. This, in turn, drives the slider 5 to slide along the sliding rod 4 toward the side wall of the housing 2 via the driven connecting rod 10, so that the oil injection pipe 6 moves to one side of the housing 2 as a whole, thus avoiding obstructing the material from falling.

[0041] After the material is added, the push rod 14 extends and drives the swing arm 13 and the active connecting rod 12 in the opposite direction. The gear meshing mechanism causes the intermediate connecting rod 9 to move in the opposite direction, pushing the slider 5 to slide along the sliding rod 4 to the middle of the mixing chamber, ensuring that the atomizing nozzle 7 is in the optimal spraying position.

[0042] The oil injection pipe 6 is moved to the side to completely avoid the inlet area, so as to avoid the material colliding with the oil injection pipe 6 during the feeding process and ensure that the material enters the mixing chamber smoothly.

[0043] The oil storage tank and hoses are all covered with an insulation layer.

[0044] The insulation layer blocks the heat exchange between the oil inside the storage tank and hose and the environment, effectively reducing oil temperature fluctuations, preventing oil from solidifying in low-temperature environments or oxidizing and deteriorating in high-temperature environments, and ensuring that the oil is always within the appropriate viscosity range for atomization.

[0045] The insulation layer enables the system to operate stably in cold or large temperature difference conditions, thus expanding the applicable geographical and seasonal limitations of the equipment.

[0046] When this utility model is in use, when it is necessary to add grease to the twin-shaft paddle mixer 1, the oil pump starts to work and delivers the grease in the oil storage tank to the oil pipe 6 through the hose.

[0047] The grease in the oil pipe 6 is atomized into oil mist through two rows of atomizing nozzles 7 and sprayed onto the working area of ​​the corresponding stirring blade 3. The oil mist is spread by the high-speed rotating stirring blade 3 and mixed evenly with the material.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
