Description

Technical Field

[0001] The present invention relates to the technical field of calcium carbide production, and in particular to a tumbling calcium carbide production device. Background Art

[0002] The chemical name of calcium carbide is calcium carbide, and its appearance is gray, brownish yellow, black or brown blocky solid, which is the basic raw material of organic synthetic chemical industry. Acetylene generated by the reaction of calcium carbide with water can synthesize many organic compounds, such as synthetic rubber, artificial resin, acetone, ketene, carbon black, etc.; at the same time, the acetylene-oxygen flame is widely used for welding and cutting of metals.

[0003] At present, most calcium carbide production devices adopt fixed reaction furnaces. For example, a patent document with the patent application number CN202021286470.6 discloses an environmentally friendly and energy-saving calcium carbide furnace, which is mainly used for the production of calcium carbide. The calcium carbide raw materials can be conveniently put in and taken out through the lifting of the lifting plate arranged in the reaction furnace, and at the same time, a series of dust reduction and cooling structures are configured.

[0004] It can be seen from the description of the above patent that it mainly adopts a fixed reaction furnace, and this structure has the following problems in the process of calcium carbide production:

[0005] First, there is a problem of uneven mixing of materials. Since the materials lack an effective dynamic mixing mechanism in the fixed furnace cavity, calcium oxide and carbon cannot be fully contacted, resulting in a limited reaction rate, and some raw materials cannot fully participate in the reaction, thereby reducing the output and quality of calcium carbide.

[0006] Second, during the feeding and discharging processes of traditional calcium carbide production devices, it is usually necessary to stop the reaction for a period of time to complete the corresponding operations. That is, when feeding, it is necessary to open the furnace door to add raw materials into the furnace, which will cause the temperature in the furnace to drop and the reaction to interrupt; when discharging, it is also necessary to open the furnace door to take out the generated calcium carbide, which will also affect the continuity of production. This intermittent production method reduces production efficiency and increases production costs.

[0007] Based on this, the present invention optimizes and improves the problems existing in the production of calcium carbide furnaces in the prior art, and hereby proposes a double-sided tumbling calcium carbide production device to better solve the problems existing in the prior art.

Detailed implementation mode

[0032] Hereinafter, embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, so they are only examples and cannot be used to limit the protection scope of the present invention. The specific structure of the present invention is as Figures 1-6 shown in the figure.

[0033] Embodiment 1: A tumbling calcium carbide production device, including a horizontal crossbeam 1, a middle feeding mechanism is installed in the middle of the horizontal crossbeam 1, and a calcium carbide turning assembly is symmetrically arranged on the left and right sides below the middle feeding mechanism. Both of the calcium carbide turning assemblies are used for producing calcium carbide. Lifting control parts are fixedly installed at the bottom ends of both ends of the horizontal crossbeam 1. The two lifting control parts are in a synchronous movement state during operation. The bottom of each calcium carbide turning assembly and the bottom of each lifting control part are fixedly installed on the top of the connecting base 2.

[0034] When the tumbling calcium carbide production device in the present invention works, first, the whole device is powered on. After the power is turned on, the plugging cover at the top of the middle feeding mechanism is removed in advance, and then the feeding equipment is controlled to put the raw materials for producing calcium carbide into the inside of the middle feeding mechanism. When the raw materials continuously enter the inside of the middle feeding mechanism, under the action of gravity and vibration force, the calcium carbide is continuously conveyed into the inside of the calcium carbide turning assemblies on both sides. Since the calcium carbide turning assemblies on both sides are in a slow rotation state and the inside is pre-heated to reach the environment for calcium carbide production, the calcium carbide raw materials are heated and processed inside the calcium carbide turning assemblies and finally continuously produce calcium carbide products. When the calcium carbide needs to be discharged, the discharge end is controlled to open, and at the same time, the calcium carbide turning assemblies are controlled to discharge materials outward in a turning state, or the calcium carbide transported to the discharge port part is picked up outward by manually cooperating with the picking equipment.

[0035] In any of the above solutions, preferably, the middle feeding mechanism includes a vertically arranged one with a plugging cover 24 at the top ( Figure 1The feed silo 3 (shown in the figure) has both its left and right ends fixedly connected to the middle of the horizontal crossbeam 1. A main vertical pipe 4 is provided at the bottom of the feed silo 3. On both sides of the bottom of the main vertical pipe 4, a three-way pipe 5 is fixedly connected respectively. The branch pipe parts on the left and right sides of the three-way pipe 5 extend movably and sealingly into the feed central pipe 6 of the calcium carbide turnover assembly and are connected to the inside of the calcium carbide turnover assembly.

[0036] When the middle feed mechanism is working, the feed silo 3 is relied on to receive calcium carbide raw materials from the outside. When the calcium carbide raw materials are delivered into the inside of the feed silo 3, they will continuously enter the inside of the main vertical pipe 4 and the three-way pipe 5 under the action of gravity, and then under the action of vibration or external pneumatic conveying, the calcium carbide raw materials are quickly conveyed to the inside of the calcium carbide turnover assemblies on both sides, and finally the feeding as required is completed.

[0037] In any of the above solutions, preferably, the calcium carbide turnover assembly includes a connecting bottom frame 7. Above the connecting bottom frame 7, an electric heating cylinder 8 is provided. Inside and outside the lower part of the electric heating cylinder 8, a feed end supporting member and a discharge end meshing supporting member are respectively installed. The bottoms of the feed end supporting member and the discharge end meshing supporting member are fixedly arranged relative to the connecting bottom frame 7. The tops of the feed end supporting member and the discharge end meshing supporting member are respectively fitted at the bottom of the feed end and the bottom of the discharge end of the electric heating cylinder 8. At the center of the feed end cover 12 of the electric heating cylinder 8, a feed central pipe 6 is provided. The feed central pipe 6 is sealingly sleeved on the outer side wall of the corresponding branch pipe part of the three-way pipe 5, and the branch pipe part can rotate around a fixed axis inside the feed central pipe 6. Along the circumference of the edge part of the discharge end cover of the electric heating cylinder 8, a plurality of product discharge pipes 9 are fixedly installed at equal intervals. The interiors of the product discharge pipes 9 are respectively connected to the calcium carbide treatment cavity inside the electric heating cylinder 8. At the end of each product discharge pipe 9, a plugging material cover 23 is detachably installed.

[0038] The calcium carbide turnover assembly relies on the feed central pipe 6 at its feed end to receive the calcium carbide raw materials transported from the upstream feed silo 3. When the calcium carbide raw materials continuously enter the calcium carbide treatment cavity inside the electric heating cylinder 8 which is in an electrically heated state and a rotating state for calcium carbide production and processing, the entire electric heating cylinder 8 needs to rotate continuously during the calcium carbide production process. During the rotation, it mainly relies on the cooperation of the feed end supporting member and the discharge end meshing supporting member to achieve stable support and slow rotation of both ends of the electric heating cylinder 8, ensuring the smooth operation of the electric heating cylinder 8 during the calcium carbide production process. When it is necessary to convey materials to the outside, it relies on opening the outlet ends of the respective product discharge pipes 9 to quickly discharge the calcium carbide products to the outside. Controlling the number of opened plugging end covers can control the discharging speed.

[0039] Preferably, in any of the above solutions, a corrugated discharge section 10 is provided on each of the product discharge pipes 9, and the orientation of the discharge port can be controlled by bending the corrugated discharge section 10.

[0040] Bending the current corrugated discharge section 10 according to the discharging requirement can quickly control the orientation of the discharge port, thereby effectively ensuring the on-demand control of the discharge direction during discharging.

[0041] Preferably, in any of the above solutions, the electric heating cylinder 8 includes a tilting turning cylinder body 11. The feeding end of the turning cylinder body 11 is tilted upward, and the discharging end is tilted downward. A feeding end cover 12 is coaxially and fixedly installed on the outer side wall of the feeding end of the turning cylinder body 11. The bottom of the outer side wall of the feeding end cover 12 abuts against the top of the feeding end supporting member. A rotating large gear 13 is coaxially and fixedly installed on the outer side wall of the discharging end of the turning cylinder body 11. The bottom of the rotating large gear 13 meshes with the top of the discharging end meshing supporting member.

[0042] The turning cylinder body 11 of the electric heating cylinder 8 adopts an existing embedded electric heating cylinder, which is a multi-layer structure and realizes internal temperature rise after being heated by the power supply. Specifically, the structure of the embedded electric heating cylinder disclosed in the patent with the patent application number CN200820042089.8 can be adopted, which will not be elaborated here.

[0043] When the turning cylinder body 11 needs to be used, its heating switch is turned on, and at the same time, the discharging end meshing supporting member is controlled to rotate. When the discharging end meshing supporting member rotates, it can drive the rotating large gear 13 to rotate. When the rotating large gear 13 rotates, it can drive the entire tilting turning cylinder body 11 to rotate slowly. The calcium carbide raw materials inside the turning cylinder body 11 will complete the production of internal calcium carbide under the control conditions of heating and other parameters.

[0044] Preferably, in any of the above solutions, the feeding end supporting member includes an inner support frame 14 provided below the feeding end of the turning cylinder body 11. Feeding end supporting rollers 15 are respectively and movably hinged on both sides of the top of the inner support frame 14. The tops of the feeding end supporting rollers 15 respectively abut against the bottom of the outer side wall of the feeding end cover 12. The inner support frame 14 is fixedly arranged relative to the connecting base 2 below it. During operation, the feeding end supporting member mainly relies on the two feeding end supporting rollers 15 to flexibly support the bottom of the feeding end of the entire turning cylinder body 11, and at the same time plays a role of supporting and guiding when the turning cylinder body 11 rotates.

[0045] Preferably, in any of the above solutions, the lifting control member adopts a locking electric cylinder 16. Controlling the locking of the two locking electric cylinders 16 can effectively ensure the relative stability of the entire structure.

[0046] Preferably, in any of the above solutions, a plurality of vibrators 17 are fixedly installed at equal intervals along the circumference on the outer side wall of the upper cylindrical section of the feed silo 3. When the vibrators 17 work, they can effectively vibrate the feed and prevent blockage, and the vibration amplitude can be adjusted according to needs.

[0047] Preferably, in any of the above solutions, the lower part of the feed silo 3 is provided with an inverted conical tube structure. The conical tube structure can ensure the effective accumulation of the calcium carbide raw materials located at the lower part, which is convenient for rapid gathering and outward discharge under the action of vibration.

[0048] Preferably, in any of the above solutions, feed bellows sections 18 are integrally formed on the branch pipe parts on the left and right sides of the three-way pipe 5. Controlling the feed bellows sections 18 can effectively cooperate with the vibration of each vibrator 17 to avoid interference.

[0049] Embodiment 2: Compared with Embodiment 1, the difference in this embodiment is that it further includes the following technical features:

[0050] Preferably, in any of the above solutions, the engaging support at the discharge end includes an outer support frame 19 arranged below the discharge end of the turning drum body 11. On both sides of the top of the outer support frame 19, drive pinions 20 are symmetrically and spaced apart. The tops of the drive pinions 20 are respectively engaged with the bottom of the rotating large gear 13. A central driving gear 21 is arranged between the two drive pinions 20. The two sides of the central driving gear 21 are respectively engaged with the drive pinions 20. The two drive pinions 20 and the central driving gear 21 are respectively movably inserted in the corresponding rotation holes on both sides of the outer support frame 19 through their corresponding gear shafts. A driving motor 22 is fixedly installed on the inner side wall of the outer support frame 19. The motor shaft of the driving motor 22 is fixedly connected with the gear shaft of the central driving gear 21. When the driving motor 22 operates, it drives the central driving gear 21 to rotate and completes the driving of the drive pinions 20, thereby driving the turning drum body 11 to rotate as required.

[0051] The engaging support at the discharge end mainly relies on the two drive pinions 20 to provide the meshing and supporting effects on the upper rotating large gear 13. When the driving motor 22 rotates, it can drive the central driving gear 21 connected thereto to rotate. The central driving gear 21 drives the drive pinions 20 engaged on both sides to operate. When the drive pinions 20 rotate, they can cooperate to drive the rotating large gear 13 to rotate. When the rotating large gear 13 rotates, it can drive the entire turning drum body 11 to rotate, thereby completing the flipping and rolling mixing of the calcium carbide raw materials placed inside it. Controlling the rotation speed of the driving motor 22 can control the mixing efficiency of calcium carbide flipping during the production process.

[0052] Specific working principle: When the tumbling calcium carbide production device of the present invention is working, first connect the entire device to the power supply. After the power supply is connected, remove the sealing cover at the top of the middle feeding mechanism in advance, and then control the feeding equipment to put the raw materials for producing calcium carbide into the inside of the middle feeding mechanism. When the raw materials continuously enter the inside of the middle feeding mechanism, under the action of gravity and vibration force, the calcium carbide is continuously transported into the inside of the calcium carbide turning components on both sides. Since the calcium carbide turning components on both sides are in a slow rotation state and the inside has been pre-heated to the environment for calcium carbide production through electric heating, the calcium carbide raw materials are heat-treated inside the calcium carbide turning components and finally continuously produce calcium carbide products. When the calcium carbide needs to be discharged, control the discharge end to open. At the same time, control the calcium carbide turning components to discharge materials outward in a turning state or manually cooperate with the picking equipment to pick up the calcium carbide transported to the discharge port part outward. In summary, it can be seen that the present invention can rely on the middle feeding mechanism set in the center to synchronously complete the synchronous feeding to the two calcium carbide turning components on both sides, effectively improving the feeding continuity and efficiency in the calcium carbide production process, and effectively ensuring the continuous and efficient production feeding of calcium carbide; when feeding the calcium carbide raw materials, relying on multiple vibrating parts can ensure the continuity of feeding during the feeding process, avoid material accumulation or blockage, and ensure the safety of feeding. When the two calcium carbide turning components are working, after connecting the power supply, they can continuously heat the calcium carbide production raw materials inside in their own rotating state. After controlling the parameters, the rapid production of calcium carbide can be completed. At the same time, after the production is completed, controlling the opening of the discharge end can quickly complete the discharge of calcium carbide products, effectively ensuring the high efficiency of production and the quick and convenient discharge of materials; the calcium carbide turning components can control the discharge of the discharge end while slowly rotating, and can also ensure the continuity of feeding during feeding, effectively reducing the downtime during feeding and discharging, and ensuring the relative continuity of the entire production process.
