Technical Field

[0001] The utility model belongs to the technical field of syrup, and in particular relates to a precise syrup metering and conveying system. Background Art

[0002] Syrup is a thick, high-concentration sugar solution made by boiling or other techniques. Due to its high sugar content, syrup can be stored for a long time without refrigeration when sealed.

[0003] However, due to the high viscosity of the syrup, there are problems with accuracy during transportation due to weight, drop and pressure difference.

[0004] In view of this, the present invention aims to provide a syrup precise metering and delivery system, which can achieve precise metering and delivery of syrup through ingenious structural design. Utility Model Content

[0005] The purpose of the utility model is to provide a syrup precise metering and delivery system to address the deficiencies of the prior art, which can achieve precise metering and delivery of syrup through ingenious structural design.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A precise metering and delivery system for syrup comprises a syrup tank, a delivery pipeline, a control device, and a syrup tank power pump which can rotate forward and reverse and is arranged on the delivery pipeline. The delivery pipeline is also connected in parallel to an electric pressure relief valve and a pneumatic pressure regulating switch arranged on the electric pressure relief valve. A flow meter is provided at the discharge end of the delivery pipeline. The syrup tank power pump, the electric pressure relief valve, the pneumatic pressure regulating switch, and the flow meter are all connected to the control device.

[0009] As an improvement of the syrup precise metering and delivery system of the utility model, the pressure sensor includes a valve body and a needle valve, a guide regulating valve, a pilot valve, a ball valve and a pressure gauge connected to the valve body.

[0010] As an improvement to the precise syrup metering and delivery system of the present invention, the syrup tank and delivery pipeline are both provided in multiple configurations, the pipelines being connected via electric three-way valves, and a pneumatic switch being provided at the outlet of each delivery pipeline. The electric three-way valves and the pneumatic switches are both connected to a control device.

[0011] As an improvement to the precise syrup metering and delivery system of the present invention, a low material sensor and a high material sensor connected to the control device are provided in the syrup tank.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0022] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0023] like Figure 1-3 As shown, the present invention provides a precise syrup metering and delivery system, comprising a syrup tank 1, several delivery pipes 2, a control device, and a syrup tank power pump 3 disposed on the delivery pipes 2, capable of forward and reverse rotation. Each delivery pipe 2 is connected in parallel to a return pipe 4 via a three-way valve. The return pipe 4 is equipped with an electric pressure relief valve 5 and a pneumatic pressure regulating switch 6 (the return pipe 4, electric pressure relief valve 5, and pneumatic pressure regulating switch 6 constitute a return device 20). A flow meter 7 is disposed at the discharge end of the delivery pipe 2. The syrup tank power pump 3, electric pressure relief valve 5, pneumatic pressure regulating switch 6, and flow meter 7 are all connected to the control device. A pressure sensor 8 is also disposed on the delivery pipe 2, connected to the control device, so that pressure data sensed by the pressure sensor 8 can be transmitted to the control device. The placement of the flow meter 7 at the discharge end of the delivery pipe 2 addresses issues such as syrup deadweight, head height, and pressure differential, improving the accuracy of flow measurement. According to tests, the flow measurement accuracy is as high as 0.03%. Furthermore, the present invention incorporates a pressure sensor 8. When the pressure in the pipeline exceeds the specified value, the control device receives the information and commands the electric pressure relief valve 5 to open, allowing the syrup to flow back, thereby achieving pressure relief. If pressure relief fails, the control device commands the syrup tank power pump 3 to reverse, allowing the syrup to flow back, maintaining and maintaining pressure in the delivery pipeline 2, further improving the stability and accuracy of syrup delivery.

[0024] The pressure sensor 8 includes a valve body 81 and a needle valve 82 connected to the valve body 81, a pilot regulating valve 83, a pilot valve 84, a ball valve 85 and a pressure gauge 86. The pressure sensor 8 of this structure is sensitive, thereby improving the accuracy of pipeline pressure testing.

[0025] There are multiple syrup tanks 1 and delivery pipelines 2. The connection between the pipelines is connected by an electric three-way valve 9. A pneumatic switch 10 is provided at the discharge port of each delivery pipeline 2. The electric three-way valve 9 and the pneumatic switch 10 are both connected to a control device, which can control the opening and closing of the electric three-way valve 9 and the pneumatic switch 10.

[0026] The syrup tank 1 is provided with a low-fill sensor 11 and a high-fill sensor 12 connected to the control device. The low-fill sensor 11 and the high-fill sensor 12 are used to sense the level of syrup in the syrup tank 1. If the syrup level is lower than the position of the low-fill sensor 11, it is judged as too low. If the syrup level is higher than the high-fill sensor 12, it is judged as too high. The control device receives the information and displays it on the display screen.

[0027] The feed inlet of delivery pipe 2 is connected to syrup tank transport vehicle 13 via slurry delivery pipe 17. A manual butterfly valve 14 and a control display 15 connected to the control device are located near the feed inlet of slurry delivery pipe 17. Manually opening manual butterfly valve 14 allows the syrup in syrup tank transport vehicle 13 to be continuously transferred to syrup tank 1, with the progress of the transfer displayed on control display 15. A pneumatic switch 10 is also located near the feed inlet of slurry delivery pipe 17.

[0028] The ends of the several delivery pipes 2 are distributed on different floors, and each floor is provided with a display screen 16 connected to the control device. Each floor is used for making different candies, such as lollipops, liquorice candies, gummy candies, enteric-coated candies, tablet candies, and milk tablet candies.

[0029] The syrup tank power pump 3 is a variable frequency speed regulation power pump, which has more precise speed regulation.

[0030] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and modifications and alterations to the thickness and material of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience only and do not constitute any limitation on the present invention.
