Description

Technical Field

[0001] This utility model relates to the field of catalyst technology, specifically a multi-channel quantitative feeding device for catalysts. Background Technology

[0002] A catalyst is generally a substance that increases the rate of a reaction without altering the overall standard Gibbs free energy change. It can also be described as a substance that increases the rate of a chemical reaction without changing the chemical equilibrium, and whose mass and chemical properties remain unchanged before and after the reaction. Statistics show that catalysts are used in over 90% of industrial processes, such as chemical, petrochemical, biochemical, and environmental protection industries. Catalysts are diverse, classified by state as liquid catalysts and solid catalysts; and by the phase of the reaction system as homogeneous catalysts and heterogeneous catalysts. Homogeneous catalysts include acid, base, soluble transition metal compound, and peroxide catalysts. Catalysts play an extremely important role in modern chemical industry.

[0003] In the prior art, CN220026953U discloses a device for quantitatively adding solid particulate catalysts, including a base plate, a first fixing rod fixed in the middle of the top of the base plate, a turntable rotatably sleeved on the outer wall of the first fixing rod, a sleeve column fixed in the middle of the turntable, and a cleaning component for cleaning residual solid particles on the inner wall of the turntable. The cleaning component includes a connecting rod fixed to the top of the first fixing rod, an annular groove opened at one end of the top of the connecting rod, a second fixing rod inserted into the bottom of the annular groove, and a threaded top of the second fixing rod.

[0004] While the above-mentioned scheme has many advantages, it also has the following disadvantages: The device uses the notch on the gear and the teeth on the turntable to drive the turntable to rotate intermittently. The stable movement of the turntable is mainly limited by the meshing of the teeth on the notch on the gear and the teeth on the turntable. Therefore, when the notch on the notch faces the turntable (the teeth on the notch on the notch do not mesh with the teeth on the turntable), the restriction on the turntable will be loosened. The turntable will rotate on its own under the action of inertia or other external forces. This will cause the teeth on the notch on the notch to collide with the teeth, obstruct or jam, and cause the turntable to malfunction, thus reducing the practicality of the multi-channel quantitative feeding device for catalyst. Furthermore, using the reciprocating start and stop of the motor to control the intermittent operation of the turntable will increase the start and stop impact of the motor bearings and increase wear, while also increasing the material on the shaft, thereby reducing the service life of the motor.

[0024] Example: Figure 1 - Figure 4 As shown, this utility model provides a technical solution for a multi-channel quantitative feeding device for catalysts, including a base plate 1, a turntable 2 rotatably mounted on the upper part of the base plate 1, a feeding assembly 3 mounted on the turntable 2, a first gear 4 and a mounting plate 5 fixedly mounted on the outer side of the turntable 2, a missing gear 6 meshing with one side of the first gear 4, the missing gear 6 rotatably mounted on the upper part of the base plate 1, a semi-circular plate 7 fixedly mounted on the upper part of the missing gear 6, and arc-shaped grooves 8 opened at both ends of the mounting plate 5, with the inner wall of the arc-shaped groove 8 contacting the outer wall of the semi-circular plate 7.

A discharge port 305 is opened on the upper part of the bottom plate 1 at the corresponding position of the quantitative hole 304. The quantitative hole 304 and the discharge port 305 are both on the same circular trajectory.

[0028] like Figure 2 As shown, a fixing rod 10 is fixedly installed on the upper part of the base plate 1, and the turntable 2 is rotatably sleeved on the outside of the fixing rod 10. A baffle 11 is fixedly sleeved on the outside of the fixing rod 10. The movable end of the baffle 11 contacts the side wall inside the groove 9. The horizontal cross section of the baffle 11 is V-shaped.

[0029] like Figure 1 As shown, a connecting rod 12 is fixedly installed at the top of the fixed rod 10. A brush plate 13 is installed at one end of the connecting rod 12, and a baffle plate is fixedly installed at the other end of the connecting rod 12. The baffle plate is in contact with one side of the baffle plate 11.

[0030] Specifically, the baffle 11, turntable 2 and feeding assembly 3 are all existing technical structures, and their usage methods are also existing technical means. Therefore, their specific forms, disassembly and assembly methods and usage methods will not be described in detail in this application.

[0031] like Figure 4 As shown, the brush plate 13 includes a top plate 131 rotatably connected to the connecting rod 12. The bottom of the top plate 131 is provided with a track groove. A track plate 132 is adapted to fit inside the cavity of the track groove. A circular plate 133 is fixedly provided at the bottom of the track plate 132. Multiple bristles are provided at the bottom of the circular plate 133. A through threaded hole is provided on the top wall inside the track groove. A threaded rod 134 is threaded inside the threaded hole. A slot 135 is provided at the corresponding position of the track plate 132 relative to the threaded hole. The bottom end of the threaded rod 134 is inserted into the cavity of the slot 135.

[0032] like Figure 4 As shown, a fixed frame is installed on the upper part of the base plate 1. A second gear 15 that meshes with the first gear 4 is rotatably connected to the fixed frame. A vertical rod is fixedly installed at the top axis of the second gear 15. Synchronous pulleys are fixedly installed at the top of the vertical rod and the upper part of the top plate 131. A synchronous belt 16 is installed between the two synchronous pulleys for transmission.

[0033] like Figure 1 As shown, a support frame is installed on the upper part of the base plate 1, and a servo motor 14 is installed on the support frame. The output shaft of the servo motor 14 is fixedly connected to the shaft of the missing gear 6, and the servo motor 14 is electrically connected to the power supply.

[0034] Working principle: First, the servo motor 14 is started, causing the fixed gear 6 at the output end of the servo motor 14 to rotate. The gear 6 drives the turntable 2 to rotate intermittently. Each rotation causes one of the metering holes 304 to be at the bottom of the discharge pipe 301 and the top of the feed port 305. Then, the solid granular catalyst is poured into the funnel 302, and then the solid granular catalyst flows from the discharge pipe 301 fixed at the bottom of the funnel 302 into the metering hole 304. Through its automation, the working efficiency is greatly improved. The rotation of the turntable 2 rotates the filled fixed granular catalyst. Then, when the metering hole 304 filled with solid granular catalyst rotates to the top, the solid granular catalyst is filled with solid granular catalyst. When the brush plate 13 is at the bottom, the excess solid catalyst particles are swept out by the brush plate 13. Then, by the rotation of the turntable 2, the swept solid catalyst particles are moved to the position of the baffle 11. When the solid catalyst particles in the metering hole 304 are filled and move to the discharge port 305 opened at the top of the bottom plate 1, the solid catalyst particles will flow out from the discharge port 305 and be packaged. At this time, when the empty metering hole 304 rotates to the bottom of the baffle 11, the solid catalyst particles remaining on the surface of the turntable 2 will enter the rotating metering hole 304. This cycle repeats, effectively reducing the waste of solid catalyst particles.

[0035] When the missing gear 6 is rotated, the missing gear 6 meshes with the first gear 4 through the meshing gear assembly, thereby causing the turntable 2 to rotate. At this time, the side wall of the semicircular plate 7 does not contact the inner wall of the arc groove 8 until the missing gear 6 no longer meshes with the first gear 4 through the meshing gear assembly. At this time, the arc side wall of the semicircular plate 7 contacts the inner wall of the arc groove 8. By utilizing the cooperation between the semicircular plate 7 and the mounting plate 5, the turntable 2 is limited. At this time, the turntable 2 cannot rotate, while the missing gear 6 continues to rotate. The side wall of the semicircular plate 7 on the missing gear 6 moves within the cavity of the arc groove 8. This process is repeated to ensure that the turntable 2 can rotate intermittently.

[0036] When the turntable 2 is rotated, the turntable 2 uses the first gear 4 to drive the second gear 15 to rotate, the second gear 15 uses the timing belt 16 to drive the top plate 131 to rotate, and the top plate 131 drives the brush plate 13 to rotate, thereby increasing the cleaning effect of the brush plate 13.

[0037] When disassembling or assembling the brush bristles, rotate the threaded rod 134 so that the bottom end of the threaded rod 134 is completely disengaged from the cavity of the slot 135. Then slide the track plate 132 in the cavity of the track groove to remove the circular plate 133. Conversely, install the circular plate 133 by sliding the track plate 134.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
