Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a sauce conveying device. Background Art

[0002] Sauces are usually transported in ton boxes, and after being transported to the designated location, rotor pumps are used to transport the materials. Figure 2 The figure shows an existing sauce conveying device, in which the input end of the rotor pump 3 is connected to the ton frame 1 through the feed hose 2, and the output end of the rotor pump 3 is connected to the temporary storage tank 10 through the feeding pipe 9. The feeding pipe 9 is a hard pipe, and the sauce is conveyed to the temporary storage tank 10 through the rotor pump 3 during transportation.

[0003] However, since the sauce is relatively viscous and has poor fluidity, and the ton frame weighs 1.5-2 tons and is difficult to erect, the rotor pump cannot form negative pressure and cannot directly transfer the sauce.

[0004] To address the problem of sauces being unable to be directly transported, the existing solution is to install a discharge pipe 22 at the output end of the rotor pump 3, and install a manual butterfly valve 21 on the discharge pipe 22. Before the sauce is transported, the pump chamber of the rotor pump 3 is first filled with water, and then the rotor pump 3 is started. With the water filling and sealing, a negative pressure is formed at the inlet of the rotor pump 3, which draws the sauce into the pump chamber, thus meeting the normal pumping requirements of the rotor pump 3. However, since the sauce at the front end will come into contact with and mix with the water, it will no longer be usable in production. Therefore, the manual butterfly valve 21 needs to be opened to discharge the water and the sauce-water mixture through the discharge pipe 22 before the sauce can be transported to the temporary storage tank 10.

[0005] However, the above existing solutions have the following problems:

[0006] 1. Cost loss: The sauce at the front end will come into contact with the injected water and need to be drained away, becoming waste, resulting in the loss of sauce. In actual production, each replacement of the ton frame will result in a loss of about 15-20kg;

[0007] 2. Hygiene hazards: There is a risk of cross-contamination between the sauce and the injected water, which can easily cause microbial indicators to exceed the standard;

[0008] 3. Low efficiency: Every time the ton frame is replaced and each time the material is extracted, the production staff needs to first inject water, then drain the injected water, and at the same time drain the mixture of sauce and water. Each operation takes about 0.3 hours, which wastes manpower.

[0009] In addition, after the conveying is completed, a large amount of sauce will remain in the feeding pipe 9, which will cause waste and increase costs. Utility Model Content

[0010] The purpose of the utility model is to provide a sauce conveying device, which can reduce the loss of sauce and has higher use efficiency.

[0011] The purpose of this utility model is achieved through the following technical solutions:

[0012] A sauce conveying device includes a rotor pump, a feed hose and a feeding pipe, the feed hose is connected to the input end of the rotor pump, and is characterized in that: it also includes a piston pump, a first control valve and a second control valve, a feeding interface and an exhaust interface are provided on the output end of the rotor pump, the first control valve and the second control valve are respectively arranged at the feeding interface and the exhaust interface, an air inlet and an air outlet are provided on the cylinder body of the piston pump, the air inlet and the air outlet are respectively provided with a first one-way valve that only allows air to enter and a second one-way valve that only allows air to discharge, the feeding pipe is connected to the feeding interface on the output end of the rotor pump, and the air inlet of the piston pump is connected to the exhaust interface on the output end of the rotor pump.

[0013] A further technical solution of the utility model is that the first control valve and the second control valve are both pneumatic butterfly valves.

[0014] A further technical solution of the utility model is: the piston pump is a pneumatic piston pump.

[0015] A further technical solution of the utility model is: the sauce conveying device also includes a purge gas pipeline, and a purge gas interface is also provided on the output end of the rotor pump. The air inlet end of the purge gas pipeline is connected to the external air source, and the air outlet end of the purge gas pipeline is connected to the purge gas interface. An air intake control valve is provided at the air outlet end of the purge gas pipeline.

[0016] A further technical solution of the utility model is that a three-stage filter and a sterile filter are provided on the purge gas pipeline.

[0017] A further technical solution of the present invention is that a third one-way valve is provided at the output end of the rotor pump.

[0018] A further technical solution of the present invention is that a flow meter is provided at the input end of the rotor pump.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When sauce delivery is needed, the utility model opens the second control valve and closes the first control valve. The piston pump then draws out the air in the rotor pump and feed hose, creating negative pressure. This allows the sauce to automatically enter the rotor pump, filling the pump chamber of the rotor pump with the sauce. This allows the rotor pump to start normally and deliver the sauce, thus resolving the problem of the rotor pump being unable to generate negative pressure and thus unable to directly deliver materials. Furthermore, the sauce will no longer be contaminated, reducing sauce loss.

[0021] In practice, after adopting the utility model, 15-20kg / ton frame of sauce can be saved in each batch. Assuming 30 batches of ton frames of sauce are delivered every day, the sauce cost is 35 yuan / kg, and the cost can be saved by 157,500 yuan per day, which produces great economic benefits.

[0022] 2. The utility model does not need to be injected with water during use, thus avoiding the risk of sauce being contaminated and eliminating health hazards.

[0023] 3. The utility model also reduces manpower and improves efficiency. In actual use, only one person is needed to complete the transportation and delivery of the sauce, which can save labor costs of about 300 yuan per day. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Example:

[0033] like Figure 1 The sauce conveying device of this embodiment is shown, which includes a rotor pump 3, a feed hose 2, a feeding pipe 9, a piston pump 8, a first control valve 5, a second control valve 4 and a purge gas pipeline 11.

[0034] The feed hose 2 is connected to the input end of the rotor pump 3, and is connected to the tonnage frame 1 filled with sauce through the feed hose 2 when in use.

[0035] The output end of the rotary pump 3 in this embodiment is equipped with a third one-way valve 15, along with a feed port 14, an exhaust port 16, and a purge gas port 17. The third one-way valve 15 only allows the sauce to be discharged from the output end of the rotary pump 3, thereby preventing the sauce from flowing back into the rotary pump 3. The first control valve 5 and the second control valve 4 are located at the feed port 14 and the exhaust port 16, respectively. Both the first control valve 5 and the second control valve 4 are pneumatic butterfly valves.

[0036] The piston pump 8 of this embodiment is a pneumatic piston pump, which uses a pneumatic mechanism to drive a piston to reciprocate within a cylinder 20. The cylinder 20 of the piston pump 8 is provided with an air inlet 23 and an air outlet 24. The air inlet 23 and air outlet 24 of the cylinder 20 are respectively equipped with a first one-way valve 6 that only allows external air to enter the cylinder, and a second one-way valve 7 that only allows air in the cylinder to be discharged.

[0037] Among them, one end of the feeding pipe 9 is connected to the feeding interface 14, and the other end is used to connect to the temporary storage tank 10. The air inlet 23 of the piston pump 8 is connected to the exhaust interface 16, so that the air in the rotor pump 3 and the feeding hose 2 can be extracted through the piston pump 8.

[0038] The purge gas pipeline 11 has an inlet connected to an external air source, which provides compressed air. The outlet of the purge gas pipeline 11 is connected to a purge gas port 17. An inlet control valve 18 is provided at the outlet of the purge gas pipeline 11. In this embodiment, the inlet control valve 18 is a ball valve. The purge gas pipeline 11 is equipped with a three-stage filter 13 and a sterile filter 12. In this embodiment, the three-stage filter 13 comprises a coarse filter, a fine filter, and an activated carbon filter. Gas entering the purge gas pipeline 11 first passes through the three-stage filter 13 to remove impurities and moisture, and then passes through the sterile filter 12.

[0039] This embodiment also includes a flow meter 19 at the input end of the rotor pump 3. This flow meter 19 is used to detect the flow rate of the sauce flowing through it. During operation, as the piston pump 8 draws air from the rotor pump 3 and the feed hose 2, creating a negative pressure that automatically causes the sauce to enter the rotor pump 3, the flow meter 19 provides a rough estimate of the amount of sauce entering the rotor pump 3. Once a certain amount of sauce has entered, the rotor pump 3 can be activated normally.

[0040] The specific use process of the sauce conveying device of this embodiment is as follows:

[0041] Before transportation, connect the feeding pipe 9 of the sauce conveying device to the temporary storage tank 10, and connect the feeding hose 2 to the tonnage frame 1 filled with sauce.

[0042] During transportation, first close the first control valve 5, open the second control valve 4, start the piston pump 8, and the piston of the piston pump 8 will reciprocate in the cylinder 20. When the piston is pulled back, it is exhausting, and the air in the rotor pump 3 and the feed hose 2 will enter the cylinder 20 through the first one-way valve 6. When the piston is pushed forward, it is exhausting, and the air in the cylinder will be discharged to the outside through the second one-way valve 7. This reciprocating motion can continuously extract the air in the rotor pump 3 and the feed hose 2, forming a negative pressure, so that the sauce in the tonnage frame 1 automatically passes through the feed hose 2 and enters the rotor pump 3. At this time, the staff can know whether the sauce has entered the rotor pump 3 through the flow meter 19.

[0043] After the piston pump 8 has been running for a certain period of time, the rotor pump 3 will be filled with enough sauce. Then the piston pump 8 will be closed, the second control valve 4 will be closed, the first control valve 5 will be opened, and the rotor pump 3 will be started. At this time, the rotor pump 3 can operate normally and smoothly pump the sauce in the ton frame 1 to the temporary storage tank 10.

[0044] In addition, after the transportation is completed, the air intake control valve 18 can be opened to connect to the external air source. The compressed air provided by the external air source will pass through the three-stage filter 13 and the sterile filter 12, and then blown into the feeding pipe 9 to purge the feeding pipe 9. The sauce remaining in the feeding pipe 9 will be blown into the temporary storage tank 10, avoiding waste.

[0045] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention, and the implementation methods of the present invention are not limited thereto. All other modifications, replacements or changes made to the above structure of the present invention based on the above contents of the present invention, in accordance with common technical knowledge and customary means in this field, without departing from the above basic technical ideas of the present invention, should fall within the scope of protection of the present invention.
