Description

Technical Field

[0001] This invention belongs to the field of tobacco processing technology, specifically referring to a feeding system and method. Background Technology

[0002] Dual-stage feeding is a common flavoring technique in cigarette production. It involves dividing the raw material into hot and cold components. Hot feeding occurs at the inlet, where the raw material is heated to a suitable temperature before being added to the cigarette raw materials. This heated material allows for better penetration into the raw materials and ensures uniform aroma distribution. Cold feeding occurs at the outlet, where the unheated material is directly added to the finished cigarette. This method primarily aims to reduce the moisture content of the cigarettes, thereby improving their quality. It effectively controls the uniformity and stability of the aroma, ultimately enhancing the overall quality of the cigarettes.

[0003] The existing feeding equipment technology for new cigarette factory production lines, although adopting a dual feeding method with hot material feeding at the inlet and cold material feeding at the outlet, has defects and shortcomings that have been restricting the improvement of production efficiency and material utilization efficiency.

[0004] The existing cold material control system for the feeding tank lacks effective management and control over storage and usage time. According to the plant's quality management department's regulations on liquid material usage, cold material should not be used for more than 48 hours after preparation and on-site use. However, in actual operation, it is often used after the storage time has been exceeded, and even the liquid material deteriorates. This not only affects product quality but also poses safety hazards to production. Summary of the Invention

[0005] To avoid reusing cold liquid materials that have exceeded their storage and usage time, and to reduce liquid material loss, this invention proposes a dual-valve flow direction adjustment component and an anti-clogging liquid material replenishment mechanism.

[0006] The technical solution adopted by the present invention is as follows: The present invention provides a feeding system, including a material tank and a feeding pipeline. The feeding pipeline includes an input pipe, and a first reversing valve is provided on the input pipe. The first outlet of the first reversing valve is connected to the material tank through the input pipe. The second outlet of the first reversing valve is connected to a buffer tank. The first outlet of the buffer tank is connected to the material tank. The second outlet of the buffer tank is connected to a recovery container. The first outlet and the second outlet of the buffer tank are respectively provided with switching valves. During the feeding process, the storage time of the liquid is controlled to avoid the liquid being used 48 hours after preparation.

[0007] Furthermore, a stirrer is provided above the interior of the buffer tank for stirring the liquid.

[0008] Furthermore, the first discharge port is equipped with an angle valve two and a quick valve. The quick valve is located above the angle valve two. The second discharge port is equipped with an angle valve one. The quick valve is used to control the flow rate of the liquid, and the angle valve two acts as a flow switch for the pipeline.

[0009] Furthermore, a suction pump is installed at the inlet end of the input pipe, and a bracket is provided at the lower end of the suction pump. The inlet end of the suction pump is connected to one end of the suction pipeline. The installation of the suction pump facilitates the feeding of liquid and the cleaning of the pipeline.

[0010] Furthermore, a recycling component is provided on the side wall of the first discharge port. The recycling component includes a discharge pipe, one end of which is connected to the upper end of the side wall of the first discharge port. A third reversing valve is provided on the discharge pipe. The reversing valve can precisely control the flow rate and save energy.

[0011] Furthermore, the input pipe is equipped with a cleaning assembly, which includes a cleaning water pipeline. One end of the cleaning water pipeline is connected to the top wall of the input pipe. The input pipe is equipped with a second reversing valve, which is located on one side of the first reversing valve. The first output port of the second reversing valve is connected to the input pipe, and the second output port of the second reversing valve is connected to a drain pipe, which can clean the residual liquid in the equipment.

[0012] Furthermore, the quick valve below the buffer tank controls the flow rate of the replenishing liquid. The flow rate of the cold material at the feed outlet is 57 kg / h, and the replenishing flow rate of the buffer tank is set to 60 kg / h, which can better match the production.

[0013] Furthermore, before feeding, the electronic belt scale sends a weight decrease signal, and the buffer tank control program enters a 1-minute countdown. When the countdown ends, the second angle valve at the bottom of the buffer tank closes, and the buffer tank stops feeding the material tank, allowing the feeding system to operate normally.

[0014] Furthermore, the control program of the buffer tank is electrically connected to the electronic belt scale and is used to receive signals transmitted by the electronic belt scale.

[0015] This solution also discloses a feeding method, which mainly includes the following steps:

[0016] Step 1: The first outlet of the first reversing valve is closed and the second outlet is open. The first outlet of the second reversing valve is open and the second outlet is closed. Angle valve 1 and angle valve 2 are both closed. The suction pump works and injects the liquid into the buffer tank. After the buffer tank is filled, the first outlet of the first reversing valve is opened and the second outlet is closed. The second reversing valve is horizontal. The suction pump works and injects the liquid into the tank.

[0017] Step 2: If there is any leftover cold material liquid from the previous day's production, it will be connected to the recovery container. The first outlet of both the first and second reversing valves will be opened and the second outlet will be closed, allowing the liquid to flow into the tank. The suction pump will then work to pump the remaining liquid into the tank.

[0018] Step 3: During the production process, the agitator at the top inside the buffer tank starts simultaneously, preventing sedimentation and blockage of the quick valve below the buffer tank. When the weight of the liquid in the tank is lower than the set weight of the anti-clogging liquid replenishment mechanism, the feeding system stops, and the angle valve 2 at the bottom of the buffer tank opens to replenish the liquid in the tank. The quick valve at the bottom of the buffer tank controls the flow rate of the replenished liquid. The flow rate of the cold material at the feeding outlet is 57 kg / h. To match the production, the replenishment flow rate of the buffer tank is set to 60 kg / h.

[0019] Step 4: When the electronic belt scale sends a weight decrease signal before feeding, the buffer tank control program enters a 1-minute countdown. When the countdown ends, the second angle valve at the bottom of the buffer tank closes, and the buffer tank stops feeding the material into the tank.

[0020] Step 5: Once the angle valve is opened, the first outlet of the third reversing valve opens and the second outlet closes. The liquid flows out of the buffer tank along the discharge pipe, and the remaining liquid in the buffer tank flows into the recovery container.

[0021] Step Six: After the recovery of the liquid material is completed, the material tank and buffer tank are cleaned. The cleaning water flows into the pipeline. At this time, the first outlet of both the first and second directional valves is closed and the second outlet is open. The cleaning water cleans the input pipe. After the cleaning is completed, the cleaning water flows into the grounded drain pipe. Angle valves one and two are both open. When the first outlet of the third directional valve is closed and the second outlet is open, the cleaning water flows into the second discharge port. The clean water flows into the buffer tank through the first directional valve to clean the buffer tank. Some of the cleaning water flows into the material tank from angle valve two to clean the material tank.

[0022] Step 7: After cleaning the material tank and buffer tank, clean the suction pipe, input pipe and suction pump. The operator places the water tank at the lower end of the suction pipe, the suction pump works, and the cleaning water enters through the suction pipe. At this time, the first outlet of the second reversing valve is closed and the second outlet is opened, and the cleaning water is discharged through the grounded drain pipe.

[0023] The beneficial effects achieved by the present invention using the above structure are as follows:

[0024] (1) The present invention improves the original cold material feeding system, controls the use and storage time of the liquid during the feeding process, avoids the liquid being used 48 hours after preparation, and facilitates the sugar kitchen operators to record and reconcile the use of the liquid.

[0025] (2) According to the regulations for the management of liquid materials in the sugar kitchen, cold liquid materials that have been prepared for more than 48 hours need to be scrapped. The present invention controls the use of liquid materials during the feeding process, which can effectively reduce the amount of cold materials that do not meet the regulations and are scrapped.

[0026] (3) The setting of the reversing valve can accurately control the flow rate and save energy. At the same time, the reversing valve has a very fast response speed and high control accuracy, and the automatic control command can be responded to and executed quickly.

[0027] (4) The fast valve is used to control the flow rate of the liquid, and the angle valve is used to switch the flow rate of the pipeline.

[0028] (5) The feed pipeline is made of stainless steel. Stainless steel pipes have good corrosion resistance and high temperature resistance, which can extend the service life of the equipment, reduce the number of maintenance, and thus improve production efficiency. Attached Figure Description

[0033] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0034] like Figure 1 As shown, the present invention proposes a feeding system, including a material tank 9 and a feeding pipeline 2. The feeding pipeline 2 includes an input pipe 8, on which a first reversing valve 10 is provided. A suction pump 6 is installed at the inlet end of the input pipe 8, and a bracket 5 is provided at the lower end of the suction pump 6. The inlet end of the suction pump 6 is connected to one end of the suction pipeline 7. The first outlet of the first reversing valve 10 is connected to the material tank 9 through the input pipe 8. The second outlet of the first reversing valve 10 is connected to a buffer tank 12. A quick valve 18 below the buffer tank 12 controls the flow rate of the replenishing liquid. The flow rate of the cold material at the feeding outlet is 57 kg / h. To match production, the replenishing flow rate of the buffer tank 12 is set to 60 kg / h. An agitator 13 is provided inside the buffer tank 12. The first outlet 15 of the buffer tank 12 is connected to the material tank 9. The second outlet 23 of the buffer tank 12 is connected to a recovery container. The first outlet 15 and the second outlet 23 of the buffer tank 12 are respectively provided with switching valves.

[0035] Angle valve 2 19 and quick valve 18 are provided on the first discharge port 15. Quick valve 18 is located above angle valve 2 19. Angle valve 1 20 is provided on the second discharge port 23. A recycling component 1 is provided on the side wall of the first discharge port 15. The recycling component 1 includes a discharge pipe 25. One end of the discharge pipe 25 is connected to the upper end of the side wall of the first discharge port 15. A third reversing valve 24 is provided on the discharge pipe 25.

[0036] The input pipe 8 is equipped with a cleaning assembly 4, which includes a cleaning water pipe 21. One end of the cleaning water pipe 21 is connected to the top wall of the input pipe 8. The input pipe 8 is equipped with a second reversing valve 11, which is located on one side of the first reversing valve 10. The first output port of the second reversing valve 11 is connected to the input pipe 8, and the second output port of the second reversing valve 11 is connected to a sewage discharge pipe 22.

[0037] Before feeding, the electronic belt scale sends a weight decrease signal, and the control program of buffer tank 12 enters a 1-minute countdown. When the countdown ends, the angle valve 2 19 at the bottom of buffer tank 12 closes, and buffer tank 12 stops feeding material into tank 9.

[0038] The control program of buffer tank 12 is electrically connected to the electronic belt scale.

[0039] In practical use, the first outlet of the first reversing valve 10 is closed and the second outlet is open; the first outlet of the second reversing valve 11 is open and the second outlet is closed; angle valve 1 20 and angle valve 2 19 are both closed; the suction pump 6 operates and injects the liquid into the buffer tank 12. After the buffer tank is filled, the first outlet of the first reversing valve 10 is opened and the second outlet is closed; the second reversing valve 11 is horizontal; the suction pump 6 operates and injects the liquid into the material tank 9. If there is residual cold liquid from the previous day's production, connect 7 to the recovery container; the first outlet of both the first reversing valve 10 and the second reversing valve 11 is open and the second outlet is closed; the liquid flows into the material tank 9; the suction pump 6 operates and... The remaining liquid is pumped into tank 9. During production, the agitator 13 inside buffer tank 12 is activated simultaneously to prevent sedimentation and blockage of the quick valve 18 below. When the weight of the liquid in tank 9 falls below the set weight of the anti-clogging liquid replenishment mechanism, the feeding system stops, and the angle valve 19 below buffer tank 12 opens to replenish the liquid into tank 9. The quick valve 18 below buffer tank 12 controls the flow rate of the replenished liquid. The flow rate of the cold material at the feeding outlet is 57 kg / h. To match production, the replenishment flow rate of buffer tank 12 is set to 60 kg / h. When the electronic belt scale sends a weight decrease signal before feeding, buffer tank 12... The control program enters a 1-minute countdown. When the countdown ends, angle valve 2 19 below buffer tank 12 closes, stopping the feeding of material tank 9 from buffer tank 12. Angle valve 1 20 opens, the first outlet of the third reversing valve 24 opens, and the second outlet closes. The liquid flows out of buffer tank 12 along the discharge pipe 25. The remaining liquid in buffer tank 12 flows into the recovery container. After the liquid recovery is completed, material tank 9 and buffer tank 12 are cleaned. Cleaning water flows into the cleaning pipe 21. At this time, the first outlet of both the first reversing valve 10 and the second reversing valve 11 is closed, and the second outlet is open. The cleaning water cleans the input pipe 8. After cleaning, the cleaning water flows into the grounded drain pipe 22. When the water flows in, both angle valve 1 (20) and angle valve 2 (19) are open, the first outlet of the third directional valve 24 is closed, and the second outlet is open. Cleaning water flows into the second discharge port 23. Clean water flows through the first directional valve 10 into the buffer tank 12 to clean the buffer tank 12. Part of the cleaning water flows from angle valve 2 (19) into the material tank 9 to clean the material tank 9. After the material tank 9 and the buffer tank 12 are cleaned, the suction pipe 7, the input pipe 8, and the suction pump 6 are cleaned. The operator places the water tank at the lower end of the suction pipe 7, the suction pump 6 operates, and cleaning water enters through the suction pipe 7. At this time, the first outlet of the second directional valve 11 is closed, and the second outlet is open. The cleaning water is discharged through the grounded drain pipe 22. This is the overall workflow of the invention. Repeat these steps for the next use.

[0040] As can be seen from the above embodiments, the beneficial effects of the present invention are as follows:

[0041] This invention improves upon the existing cold material feeding system by controlling the storage time of the molten material during the feeding process. This prevents the molten material from being used more than 48 hours after preparation, facilitating the recording and reconciliation of molten material usage by sugar kitchen operators. According to the sugar kitchen's molten material management regulations, cold molten material exceeding 48 hours of preparation time must be discarded. This invention effectively reduces the amount of non-compliant cold molten material that needs to be discarded by controlling molten material usage during the feeding process. The three-way solenoid valve allows for precise flow control, saving energy. Furthermore, the three-way solenoid valve has a very fast response speed and high control accuracy, enabling rapid response and execution of automated control commands. A fast valve is used to control the molten material flow, while an angle valve acts as a pipeline flow switch. The input pipe is made of stainless steel, which has good corrosion resistance and high temperature resistance, extending the service life of the equipment, reducing maintenance frequency, and thus improving production efficiency.

[0042] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
