Description

Technical Field

[0001] The utility model relates to the field of feeding devices, in particular to a feeding device for a microwave cracking furnace. Background Art

[0002] With growing environmental awareness and the continuous development of waste treatment technology, microwave cracking furnaces are becoming increasingly popular as efficient and environmentally friendly waste treatment equipment. Microwave cracking furnaces use microwave generators to generate microwave energy, which is absorbed by polar molecules in the material, causing friction and collisions between the molecules, thereby converting the microwave energy into heat. In the absence or absence of oxygen, this heat breaks down high-molecular-weight organic matter into smaller compounds, such as combustion gases, oil, and carbon black. This process, unlike incineration, does not require an external heat source, but instead utilizes the material's own absorption of microwave energy to generate heat and achieve cracking.

[0003] When using a microwave cracking furnace, a feeding device is also used. Since the impurities and particles in the raw materials are of different sizes, the feeding pipeline will be blocked during feeding, thereby affecting the normal operation of the cracking furnace and reducing production efficiency. The existing feeding equipment cannot crush the impurities in the raw materials while feeding, resulting in blockage of the raw materials and cannot effectively maintain the stability of the raw materials entering the cracking furnace. It is inconvenient to use. Therefore, further optimization is made to address the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a feeding device for a microwave cracking furnace, which solves the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A feeding device for a microwave cracking furnace, comprising a feeding cylinder, a transmission cylinder and a bracket, wherein the feeding cylinder is fixedly connected to the top of the right end of the transmission cylinder, and the bracket is fixedly connected to the bottom of the transmission cylinder;

[0006] A rotating sleeve is provided in the middle of the bottom plate of the feed barrel, and a crushing blade is provided on the surface of the rotating sleeve for crushing the raw material. A rotating shaft is provided inside the transmission barrel, and a transmission piece and a crushing blade are provided on the surface of the rotating shaft. A driving assembly is provided inside the feed barrel and the transmission barrel, and is used to drive the rotating sleeve and the rotating shaft to rotate. A discharge port is provided at the bottom of the left end of the transmission barrel, and a baffle is provided inside the transmission barrel near the discharge port. An electric telescopic rod is fixedly connected to the bottom of the transmission barrel near the baffle, and its output end is fixedly connected to the right end of the baffle. An adjusting part is provided on the upper surface of the right end of the baffle, and is used in conjunction with the driving assembly.

[0007] The utility model has the following beneficial effects:

[0008] The feeding device for a microwave cracking furnace has a feeding cylinder connected to a discharge pipe, and a transmission cylinder connected to a feed port of the cracking furnace. When raw materials enter the feeding cylinder, a driving assembly drives a rotating sleeve to rotate, and a crushing blade is used to crush larger particles in the raw materials. The crushed raw materials fall into the transmission cylinder. The rotation of the transmission blade drives the raw materials to be uniformly discharged into the cracking furnace, thereby avoiding feed blockage and stably and effectively maintaining feed uniformity.

[0009] The feeding device for a microwave cracking furnace can drive the raw materials accumulated on the bottom plate of the feeding barrel to fall into the interior of the transmission barrel when the scraper on the surface of the inner rod rotates, thereby avoiding accumulation. The second crushing blade on the surface of the rotating shaft can crush the particles that the first crushing blade has not touched, thereby facilitating the crushing of the raw materials and reducing blockage. The feeding frame can be disassembled from the feeding barrel, making it convenient to disassemble and replace the first crushing blade on the surface of the rotating sleeve rod.

[0010] A feeding device for a microwave cracking furnace has a baffle that can move left and right via an electric telescopic rod to close and open a discharge port. When an appropriate amount of raw materials accumulates on the upper surface of the baffle and a pressure sensor inside the baffle reaches a set threshold, an electrical signal is sent to a control module. The control module controls the electric telescopic rod to drive the baffle to move right, thereby facilitating the quantitative discharge of raw materials into the cracking furnace. When the baffle moves to the right, it synchronously drives a push rod to move, separating gear 2 from the vertical rod. At this time, the rotating shaft stops rotating to prevent the raw materials from continuing to be transported to the left. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] See also Figures 1 to 5 The utility model provides a feeding device for a microwave cracking furnace; it includes a feeding cylinder 1, a transmission cylinder 2 and a bracket 3, the feeding cylinder 1 is fixedly connected to the top of the right end of the transmission cylinder 2, and the bracket 3 is fixedly connected to the bottom of the transmission cylinder 2.

[0019] A rotating sleeve is provided in the middle of the bottom plate of the feed barrel 1, and a crushing blade 4 is provided on the surface of the rotating sleeve for crushing the raw materials.

The transmission cylinder 2 is arc-shaped and can be easily fitted with the transmission piece 6 inside it, which is convenient for conveying the material.

[0021] The equipment can be supported by the bracket 3, and the surface of the bracket 3 is provided with fixing bolts, which are convenient for installation with the cracking furnace to maintain the stability of the feeding equipment during use;

[0022] The discharge port 8 at the bottom of the transmission cylinder 2 can be connected to the cracking furnace. The driving assembly can drive the rotating sleeve to rotate, and at the same time drive the rotating shaft 5 to rotate. The crushing blade 1 4 and the crushing blade 2 7 are used to crush the raw materials. At the same time, the transmission piece 6 is used to transport the crushed raw materials to the interior of the cracking furnace, thereby improving the cracking efficiency of the raw materials.

[0023] A discharge port 8 is provided at the bottom of the left end of the transmission cylinder 2, and a baffle 9 is provided inside the transmission cylinder 2, near the discharge port 8. An electric telescopic rod 10 is fixedly connected to the bottom of the transmission cylinder 2 near the baffle 9, and its output end is fixedly connected to the right end of the baffle 9. An adjustment part is provided on the upper surface of the right end of the baffle 9, and is used in conjunction with the drive assembly.

[0024] The feed barrel 1 includes a feed frame 11 detachably connected to the top thereof, a feed chute 12 is provided on the bottom plate of the feed barrel 1, and the rotating sleeve includes an inner rod 13 inserted into the bottom plate of the feed barrel 1 and a sleeve 14 sleeved on the outer wall of the top of the inner rod 13. A gear 15 is provided at the top of the inner rod 13 and the sleeve 14.

[0025] like Figure 2 As shown, there are several discharge chutes 12 on the bottom plate of the transmission cylinder 2, and they are evenly arranged on the upper surface of the bottom plate to facilitate discharge. The electric telescopic rod 10 is fixedly connected to the bottom of the transmission cylinder 2 through a bracket. A slideway adapted to the baffle 9 is provided inside the transmission cylinder 2. When the baffle 9 slides to the left, the discharge port 8 is closed. When the baffle 9 moves to the right, it is convenient to retract inside the transmission cylinder 2.

[0026] An auxiliary plate 16 is fixedly connected to the inner wall of the feed barrel 1, and the top ends of the inner rod 13 and the sleeve 14 are arranged inside the left end of the auxiliary plate 16. A scraper 17 is fixedly connected to the surface of the bottom end of the inner rod 13, near the discharge chute 12.

[0027] The auxiliary plate 16 can support the rotating sleeve rod to maintain stability in use, and the scraper 17 can push the transported materials accumulated in the discharge chute 12 to fall into the interior of the transmission cylinder 2, thereby reducing the accumulation of raw materials.

[0028] The driving assembly includes a driving block 18 fixedly connected to the right side of the transmission cylinder 2, a gear rod 19 provided at the output end of the driving block 18, and a vertical rod 20 provided inside the feed cylinder 1 and close to the gear rod 19. The left end of the gear rod 19 passes through the inner wall of the feed cylinder 1 and extends to the interior of the auxiliary plate 16 to engage with the gear 15.

[0029] The adjusting part includes a connecting rod 21 fixedly connected to the right end of the baffle 9, a gear 22 provided at the right end of the rotating shaft 5, and a push rod 23 sleeved on the surface of the gear 22. A spring 24 is fixedly connected to the right side of the bottom of the push rod 23, and the other end of the spring 24 is fixedly connected to the inner wall of the transmission cylinder 2.

[0030] like Figure 2As shown, the driving block 18 is started (with a motor or an electric motor as the driving source), and the gear rod 19 and the vertical rod 20 are synchronously driven to rotate synchronously. At this time, the rotating sleeve rod at the other end of the gear rod 19 rotates synchronously, and the crushing blades on its surface are used to crush the larger particles in the raw materials. The crushed raw materials fall into the interior of the transmission cylinder 2 through the discharge chute 12. When the gear 22 is engaged with the bottom end of the vertical rod 20, the rotating shaft 5 is synchronously driven to rotate, and the transmission piece 6 on its surface is used to transport the raw materials, and the raw materials are discharged through the discharge port 8. At the same time, the crushing blade 2 7 on its surface can crush the raw materials that have not been crushed by the crushing blade 1 4 to maintain the uniformity of the raw material particles.

[0031] When the electric telescopic rod 10 drives the baffle 9 to retract toward the inside of the transmission cylinder 2, the baffle 9 drives the connecting rod 21 to move to the right, and at the same time uses the push rod 23 to squeeze the spring 24. At this time, the gear 22 is separated from the gear at the bottom end of the vertical rod 20, and the rotating shaft 5 stops rotating, which facilitates the cessation of the transportation of raw materials. When the push rod 23 is no longer squeezed by the connecting rod 21, the spring 24 is reset.

[0032] The bottom end of the vertical rod 20 is meshed with the gear 2 22 , and the top end is meshed with the gear rod 19 . A pressure sensor 25 is provided inside the baffle 9 . A control module is fixedly connected to the right side of the transmission cylinder 2 and is electrically connected to the pressure sensor 25 .

[0033] In the above, the driving block 18, the electric telescopic rod 10 and the pressure sensor 25 are all existing well-known technologies and are only cited here. The specific structure will not be described in detail.

[0034] The electrical components mentioned in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that performs control such as a computer.

[0035] In the present invention, the working steps of the device are as follows:

[0036] When in use, the feed cylinder 1 is connected to the external discharge pipe, and the discharge port 8 at the bottom of the transmission cylinder 2 is connected to the feed port of the cracking furnace. When the raw material enters the interior of the feed cylinder 1, the driving assembly drives the rotating sleeve to crush the raw material, and then the crushed raw material enters the interior of the transmission cylinder 2 through the discharge chute 12, synchronously driving the transmission piece 6 to rotate, so that the raw material is transported from the discharge port 8 to the interior of the cracking furnace;

[0037] When it is necessary to quantitatively convey raw materials, the discharge port 8 is closed by the baffle 9. When the pressure sensor 25 reaches the set threshold, an electrical signal is sent to the control module. The control module controls the electric telescopic rod 10 to drive the baffle 9 to move to the right, so as to open the discharge port 8 and discharge the quantitative raw materials into the interior of the cracking furnace. When the baffle 9 continues to move to the right, it synchronously drives the push rod 23 to move, so that the gear 2 22 is separated from the vertical rod 20. At this time, the transmission piece 6 stops conveying raw materials to the discharge port 8, which is more convenient to use.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
