Description

Technical Field

[0001] The utility model relates to the technical field of acetylene production devices, in particular to a novel acetylene generator. Background Art

[0002] An acetylene generator is a device used to produce acetylene gas by chemically reacting water and calcium carbide (CaC2). A reaction plate and a stirring device are provided inside the acetylene generator. After the material enters the generator, it falls onto the reaction plate. Water is sprayed onto the material through a spray valve on the upper part of the generator, causing the calcium carbide to undergo a hydrolysis reaction to produce acetylene gas. In order to increase the reaction speed and the utilization rate of calcium carbide, the material needs to be fully stirred by a stirring device. The stirring device is provided with a rake arm and rake teeth to stir the calcium carbide material on the reaction plate.

[0003] Although the multi-layer reaction plates of the existing acetylene generator are misaligned and leaking, the rake teeth of the multi-layer stirring rods are in the same direction, and each layer of the reaction plates is set horizontally. When the carbide slag comes into contact with water, it sticks together to form lumps, causing the accumulation of carbide and carbide slag on the reaction plates, resulting in the unreacted carbide being unable to react with water better. Moreover, if it sticks to the reaction plates for a long time, the device will not be able to operate normally, affecting normal production.

[0004] To this end, we propose a new type of acetylene generator. Summary of the Invention

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention provides a novel acetylene generator.

[0006] In order to achieve the above-mentioned purpose of the invention, the technical solution adopted by the present utility model is:

[0007] A novel acetylene generator comprises: a tank body, with an air outlet and a feed port on the top and a discharge port on the bottom; a first reaction plate, the edge of which is connected to the inner wall of the tank body by a plurality of connecting rods, the first reaction plate being a conical plate with a high middle portion and a low outer side; a second reaction plate, the edge of which is fixedly connected to the inner wall of the tank body, a discharge port being opened at the center of the second reaction plate, the second reaction plate being located below the first reaction plate, the second reaction plate being a funnel-shaped plate with a low middle portion and a high outer side; a drive motor being arranged at the bottom of the tank body; a stirring shaft being vertically inserted into the tank body, the stirring shaft comprising an upper shaft section and a lower shaft section, the lower shaft section being connected to the output shaft of the drive motor, the upper shaft section and the lower shaft section being connected to the output shaft of the drive motor, The shaft sections are transmission connected, the upper shaft section is connected with a first stirring rod, and the lower shaft section is connected with a second stirring rod. The first stirring rod and the second stirring rod are both provided with rake teeth, and the rake teeth on the first stirring rod are tilted outward along the rotation direction of the upper shaft section, and the rake teeth on the second stirring rod are tilted inward along the rotation direction of the lower shaft section; the first stirring rod is located above the first reaction plate and matches the inclination of the first reaction plate, and the second stirring rod is located above the second reaction plate and matches the inclination of the second reaction plate; two water spray pipes are provided, and both water spray pipes extend into the tank body from the side wall of the tank body, and the two water spray pipes are respectively located above the first stirring rod and the second stirring rod.

[0008] By setting the first reaction plate as a conical plate and the second reaction plate as a funnel-shaped plate, and tilting the rake teeth on the first stirring rod outward along the rotation direction of the upper shaft section, the first reaction plate can be better cooperated with to push the calcium carbide and carbide slag from the edge of the first reaction plate, so that they fall onto the second reaction plate for reaction. By tilting the rake teeth on the second stirring rod inward along the rotation direction of the lower shaft section, the second reaction plate can be better cooperated with to push the calcium carbide and carbide slag from the center position of the second reaction plate, so that they fall to the discharge port for discharge. This setting makes the rolling speed of calcium carbide and carbide slag faster, less likely to stick together into blocks, and is conducive to the reaction.

[0009] It is further defined that the upper shaft section and the lower shaft section achieve reverse rotation through a reversing box, the reversing box includes a first conical tooth, a second conical tooth, a third conical tooth and a shell, the shell is fixedly connected to the first reaction plate, the first conical tooth is fixedly connected to the lower end head of the upper shaft section, the second conical tooth is fixedly connected to the upper end head of the lower shaft section, the first conical tooth and the second conical tooth are respectively engaged with the third conical tooth, and the third conical tooth is rotatably connected to the shell.

[0010] The upper shaft section and the lower shaft section are rotated in opposite directions through the reversing box, driving the first stirring rod and the second stirring rod to stir in opposite directions. The falling calcium carbide can form a reverse resistance to the calcium carbide due to the opposite rotation direction of the lower layer, causing it to rotate in the opposite direction. This can change the rotation direction of the calcium carbide or carbide slag, and can also make the falling calcium carbide or carbide slag more dispersed, further increasing its contact area with water and improving the reaction efficiency. The first conical teeth are engaged with the third conical teeth, and the second conical teeth are also engaged with the third conical teeth. The motor drives the lower shaft section to rotate and drive the second conical teeth to rotate. The second conical teeth rotate and drive the third conical teeth to rotate. The third conical teeth drive the first conical teeth to rotate to achieve reverse rotation of the first and second conical teeth. The shell is fixed on the first reaction plate to prevent it from rotating. The structure is simple and easy to manufacture.

[0011] It is further defined that the shell includes a left shell and a right shell, the left shell and the right shell are fixed by bolts, the top surface of the right shell is fixedly connected to the bottom surface of the first reaction plate, and the third conical tooth is rotatably connected to the right shell; setting the shell into a left shell and a right shell makes it more convenient for us to install the reversing box.

[0012] It is further defined that there are a plurality of first stirring rods, and the plurality of first stirring rods are connected to the upper shaft section through a first shaft sleeve, and there are also a plurality of second stirring rods, and the plurality of second stirring rods are connected to the upper shaft section through a second shaft sleeve.

[0013] It is further defined that the rake teeth include long rake teeth and short rake teeth, and the two adjacent first stirring rods are respectively provided with long rake teeth and short rake teeth, and the two adjacent second stirring rods are also respectively provided with long rake teeth and short rake teeth; providing long rake teeth and short rake teeth on the adjacent stirring rods can reduce the pressure of the driving motor during rotation and stirring, and prevent the stirring rod from being stuck by calcium carbide and causing the motor to burn out.

[0015] It is further defined that the bottom surface of the tank body is an eccentric cone, the drive motor is arranged on the bottom surface corresponding to the axis of the tank body, and the discharge port is arranged at the cone head of the bottom surface of the tank body; such a staggered arrangement of the bottom surface structure of the tank body is more reasonable.

[0016] The beneficial effects of the utility model are: by coordinating the inclined rake teeth of the stirring rod corresponding to the reaction plates with different inclined directions, the calcium carbide feeding speed can be increased, calcium carbide accumulation can be avoided, the reaction is more thorough, the stirring pressure is small, and the service life is long.
