Description

Technical Field

[0001] The utility model relates to the technical field of additive mixing devices, in particular to a bio-alcohol fuel additive mixing device. Background Art

[0002] Bio-alcohol fuel is an alcohol fuel made from biomass through fermentation or other biochemical processes, and its main components include methanol, ethanol, butanol, etc. Bio-alcohol fuel belongs to renewable energy and is usually used to replace or partially replace traditional fossil fuels (such as gasoline and diesel) to reduce greenhouse gas emissions and dependence on fossil energy. Additives are usually added during the production process of bio-alcohol fuel to improve its performance, stability and applicability. The main functions of additives are to improve the combustion characteristics of the fuel, prevent corrosion, enhance stability, reduce emissions, etc. The mixing uniformity of additives directly affects the performance and combustion efficiency of the fuel.

[0003] The Chinese utility model patent authorization announcement number CN219502751U proposes a production device for bio-alcohol fuel additives, including a reaction tank. The top of the reaction tank is equipped with a feeding end, the bottom of the reaction tank is equipped with a discharging end, and a driver is fixedly connected to the center of the bottom of the reaction tank. The bio-alcohol fuel additives in this device rotate and disperse through the dispersion holes under the action of centrifugal force, improving the mixing effect of solid-liquid bio-alcohol fuel additives. The dispersion holes are continuously cleaned by a brush layer, effectively preventing the blockage of the dispersion holes. However, there is still a possibility that the dispersion holes are not cleaned thoroughly and blocked only by the brush, and the additives are dispersed under the action of centrifugal force and may be thrown onto the inner wall of the reaction tank above the liquid level, resulting in inaccurate additive dosage. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a bio-alcohol fuel additive mixing device that can effectively prevent the blockage of the material dispersion holes and improve the mixing effect at the same time.

[0005] The bio-alcohol fuel additive mixing device described in the utility model includes a mixing tank. The top of the mixing tank is provided with a feeding port, the bottom of the mixing tank is provided with a discharging port, a stirring shaft is arranged in the mixing tank, several material dispersion ports are opened at the top of the mixing tank, a material dispersion pipe is arranged on the material dispersion port, the pipe wall of the material dispersion pipe is hermetically and fixedly connected to the mixing tank, a material dispersion bottom plate is arranged at the bottom of the material dispersion pipe, several material dispersion holes are opened on the material dispersion bottom plate, a material dispersion cover is arranged at the top of the material dispersion pipe, a push rod slides through the material dispersion cover and the material dispersion bottom plate, the lower end of the push rod sequentially passes through the material dispersion cover and the material dispersion bottom plate and is fixedly connected to a blocking plate, the blocking plate is arranged below the material dispersion bottom plate, several blocking blocks corresponding to the material dispersion holes are arranged on the blocking plate, and the blocking blocks are fitted with the material dispersion holes; the upper end of the push rod is fixedly connected to the output end of the up-and-down reciprocating motion mechanism through a connecting rod one.

[0006] Preferably, the stirring shaft penetrates through the bottom of the mixing tank and is rotatably and sealingly connected to the mixing tank. A plurality of stirring blades are provided on the stirring shaft, and the lower end of the stirring shaft is connected to the output end of a rotating motor provided at the bottom of the mixing tank.

[0007] Preferably, a feeding port is provided on the bulk material cover to facilitate the addition of additives.

[0008] Preferably, the reciprocating up-and-down motion mechanism is a pneumatic cylinder or a hydraulic cylinder, and the output end of the reciprocating up-and-down motion mechanism is the piston rod of the pneumatic cylinder or the hydraulic cylinder.

[0009] Preferably, the upper surface of the plugging plate is a conical surface, and a conical block is provided at the top of the plugging block. The conical surface facilitates the falling of the additive and prevents the additive from remaining on the plugging plate; the conical block makes it more convenient for the plugging block to enter the bulk material hole.

[0010] Preferably, a dispersion shaft is horizontally provided at the inner bottom of the mixing tank. Dispersion rods are provided on the dispersion shaft. One end of the dispersion shaft is rotatably connected to a fixed block fixedly provided at the bottom of the mixing tank, and the other end of the dispersion shaft is rotatably connected to the side wall of the mixing tank. A driven gear is fixedly provided on the dispersion shaft, and the dispersion shaft is fixedly connected to the center of the driven gear. The driven gear is meshed with a vertically arranged driving rack. The driving rack is fixedly connected to the output end of the reciprocating up-and-down motion mechanism through a second connecting rod.

[0011] Preferably, the dispersion shaft is arranged along the radial direction of the mixing tank. The dispersion shaft penetrates through the side wall of the mixing tank and is rotatably and sealingly connected to the mixing tank. A driven gear is provided at one end of the dispersion shaft extending out of the mixing tank. The stirring shaft penetrates through the fixed block and is rotatably connected to the fixed block.

[0012] Preferably, a chute parallel to the driving rack is provided on the side wall of the mixing tank. A slider is slidably connected in the chute, and the slider is fixedly connected to the driving rack.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The additive is placed in the bulk material pipe. The push rod is driven by the reciprocating up-and-down motion mechanism to move up and down, so that the plugging plate moves up and down. When the plugging plate moves downward, the additive leaks out from the bulk material hole and falls onto the material in the mixing tank after passing through the plugging plate (since the plugging plate is always in a moving state, even if the additive falls onto the plugging plate, it will be shaken off during the movement). When the plugging plate moves upward, the plugging block on the plugging plate inserts into the bulk material hole to prevent the additive from leaking out; thus reciprocating, the plugging block reciprocates in and out of the bulk material hole, avoiding the blockage of the bulk material hole;

[0015] 2. When the reciprocating up-and-down motion mechanism moves up and down, it will also drive the driving rack to move up and down. The driving rack drives the driven gear to rotate forward and backward, so that the dispersion shaft rotates. Under the action of the dispersion rods, the material located in the lower part of the mixing tank is subjected to a longitudinal shearing force, avoiding the sedimentation of powdery materials at the bottom and causing uneven dispersion, and improving the mixing effect.

[0016] 3. The utility model is convenient to use, and multiple material discharging openings can be arranged to facilitate the simultaneous addition of multiple additives. Description of the Drawings

Detailed Embodiments

[0022] The following will clearly and completely describe the utility model with reference to the accompanying drawings.

[0023] Embodiment 1

[0024] As Figure 1 , Figure 2 shown, the bio - alcohol fuel additive mixing device described includes a mixing tank 1. A feed inlet 2 is provided at the top of the mixing tank 1, a discharge outlet 3 is provided at the bottom of the mixing tank 1, a stirring shaft 4 is provided inside the mixing tank 1, a plurality of material discharging openings 5 are formed at the top of the mixing tank 1, a material discharging pipe 6 is provided on the material discharging opening 5, and the pipe wall of the material discharging pipe 6 is fixedly and sealingly connected to the mixing tank 1. As Figure 4 shown, a material discharging bottom plate 7 is provided at the bottom of the material discharging pipe 6, a plurality of material discharging holes 8 are formed on the material discharging bottom plate 7, a material discharging cover 9 is provided at the top of the material discharging pipe 6, a push rod 10 is slidably penetrated through the material discharging cover 9 and the material discharging bottom plate 7. The lower end of the push rod 10 sequentially passes through the material discharging cover 9 and the material discharging bottom plate 7 and is fixedly connected to a sealing plate 11. The sealing plate 11 is arranged below the material discharging bottom plate 7, and a plurality of sealing blocks 12 corresponding to the material discharging holes 8 are provided on the sealing plate 11. The sealing blocks 12 are in fit with the material discharging holes 8; the upper end of the push rod 10 is fixedly connected to the output end of the reciprocating up - and - down motion mechanism through a connecting rod one 13.

[0025] As Figure 2As shown, the stirring shaft 4 penetrates through the bottom of the mixing tank 1 and is rotatably and sealingly connected to the mixing tank 1. A number of stirring blades 14 are provided on the stirring shaft 4, and the lower end of the stirring shaft 4 is connected to the output end of a rotating motor 15 provided at the bottom of the mixing tank 1.

[0026] As Figure 3 shown, a feeding port 16 is provided on the bulk material cover 9.

[0027] The up-and-down reciprocating motion mechanism is a pneumatic cylinder or a hydraulic cylinder, and the output end of the up-and-down reciprocating motion mechanism is a piston rod.

[0028] The upper surface of the plugging plate 11 is a conical surface, and a conical block is provided at the top of the plugging block 12.

[0029] The working process is as follows: The additive is put into the bulk material pipe 6 through the feeding port 16. At this time, the plugging block 12 is inserted into the bulk material hole 8. The push rod 10 is driven to move up and down by a pneumatic cylinder or a hydraulic cylinder, so that the plugging plate 11 moves up and down. When the plugging plate 11 moves downward, the plugging block 12 is pulled out from the bulk material hole 8, and the additive leaks out from the bulk material hole 8 and falls onto the material in the mixing tank 1 after passing through the plugging plate 11 (because the plugging plate 11 is always in a moving state, even if the additive falls onto the plugging plate 11, it will be shaken off during the movement, and the upper surface of the plugging plate 11 is a conical surface, so it is not easy to retain the material). When the plugging plate 11 moves upward, the plugging block 12 on the plugging plate 11 is inserted into the bulk material hole 8 to prevent the additive from leaking out; repeating like this, the plugging block 12 reciprocates in and out of the bulk material hole 8, avoiding the blockage of the bulk material hole 8 and at the same time realizing the addition of the additive into the mixing tank 1.

[0030] Embodiment 2

[0031] On the basis of Embodiment 1, as Figure 2 shown, a dispersion shaft 17 is horizontally provided at the bottom inside the mixing tank 1. Dispersion rods 18 are provided on the dispersion shaft 17. One end of the dispersion shaft 17 is rotatably connected to a fixed block 19 fixedly provided at the bottom of the mixing tank 1, and the other end of the dispersion shaft 17 is rotatably connected to the side wall of the mixing tank 1. A driven gear 20 is fixedly provided on the dispersion shaft 17, and the dispersion shaft 17 is fixedly connected to the center of the driven gear 20. The driven gear 20 is meshed with a vertically arranged driving rack 21, and the driving rack 21 is fixedly connected to the output end of the up-and-down reciprocating motion mechanism through a connecting rod two 22.

[0032] Specifically, the dispersion shaft 17 is arranged along the radial direction of the mixing tank 1.

A driven gear 20 is provided at one end of the dispersion shaft 17 extending out of the mixing tank 1, and the stirring shaft 4 passes through the fixed block 19 and is rotatably connected to the fixed block 19.

[0034] The working process is as follows: When the pneumatic cylinder or hydraulic cylinder moves up and down, it will drive the driving rack 21 to move up and down. The driving rack 21 drives the driven gear 20 to rotate forward and backward, so that the dispersion shaft 17 rotates. Under the action of the dispersion rod 18, the materials located at the lower part of the mixing tank 1 are subjected to longitudinal shear force, avoiding the uneven dispersion caused by the powder materials sinking to the bottom and improving the mixing effect.
