Description

Technical Field

[0001] The utility model relates to the field of material mixing, and particularly relates to a feeding system. Background Art

[0002] In some production processes, a specified amount of material needs to be added into multiple containers. The existing feeding device includes a feeding part, a feeding pipe and a feeding adjusting part. The two ends of the feeding pipe are respectively connected to the feeding part and the reaction kettle; the feeding adjusting part includes a feeding regulating valve, a flowmeter and a flow regulating part. The feeding regulating valve and the flowmeter are connected in series on the feeding pipe, and both the feeding regulating valve and the flowmeter are electrically connected to the flow regulating part; the flowmeter is used for measuring the amount of raw materials added into the reaction kettle, and the flow regulating part is used for adjusting the opening and closing of the feeding regulating valve, and further adjusting the opening and closing of the feeding pipe. The above feeding device can accurately measure and quickly adjust the amount of solvent added into the reaction kettle.

[0003] The existing feeding device has the following problems: controlling the opening and closing of the feeding regulating valve through the flowmeter has a high control cost.

[0004] Based on the above situation, there is an urgent need for a feeding system to solve the problem of high control cost. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem of high control cost for the existing feeding device by controlling the opening and closing of the feeding regulating valve through the flowmeter.

[0006] The technical solution of the utility model is as follows:

[0007] A feeding system includes:

[0008] A feeding tank for storing a feeding liquid;

[0009] A one-way component connected to the feeding tank;

[0010] A quantitative chamber connected to the one-way component and used for measuring a specified volume of the feeding liquid;

[0011] A shunt component connected to the one-way component;

[0012] A number of storage tanks connected to the shunt component.

[0013] For the existing feeding device, controlling the opening and closing of the feeding regulating valve through the flowmeter has a high control cost. In this solution, after measuring a specified volume of the feeding liquid by the quantitative chamber, it is transported to the shunt component under the action of the one-way component, and then flows into the specified storage tank. The quantitative process of the feeding liquid does not require a flowmeter, thus solving the problem of high control cost.

[0014] Further, to prevent the feeding liquid in the metering chamber from flowing back into the feeding tank, one feasible solution is as follows: The one-way component includes a pipe body, and two support frames are formed inside the pipe body. An elastic valve flap is installed on the support frame. When this solution is adopted, when the feeding liquid enters the metering chamber from the feeding tank, the elastic valve flap close to the feeding tank is pushed open, and the elastic valve flap far from the feeding tank naturally closes. After the metering is completed, the elastic valve flap close to the feeding tank naturally closes, and the feeding liquid pushes open the elastic valve flap far from the feeding tank and flows into the shunt component, improving the metering accuracy of the feeding liquid.

[0015] Further, the metering structure of the metering chamber is not uniquely defined in this solution. One feasible solution is as follows: A piston is arranged in the metering chamber, and the piston is connected with a driving part. When this solution is adopted, the driving part drives the piston to reciprocate within a specified stroke, thereby metering a specified volume of the feeding liquid and discharging it through the one-way component.

[0016] Further, the specific structure of the driving part is not uniquely defined in this solution. One feasible solution is as follows: The driving part includes an intermediate rod connected to the piston. The intermediate rod is rotatably connected with a rotating rod, and the rotating rod is connected with a motor set. When this solution is adopted, the motor set drives the rotating rod, the intermediate rod, and the piston to move in sequence, and can convert the circular motion into a linear reciprocating motion.

[0017] Further, to adjust the stroke of the piston, one feasible solution is as follows: A number of adjusting holes are formed on the rotating rod. By rotatably connecting the intermediate rod to different adjusting holes, the stroke of the piston can be adjusted conveniently and quickly.

[0018] Further, the specific structure of the shunt component is not uniquely defined in this solution. One feasible solution is as follows: The shunt component includes a delivery pipe connected to the one-way component. A three-way valve is arranged between the delivery pipe and the storage tank. When this solution is adopted, by controlling the three-way valve, the flow direction of the feeding liquid can be changed, so that the feeding liquid flows into the specified storage tank.

[0019] Compared with the existing technology, the beneficial effects of the present utility model are as follows:

[0020] First, after measuring a specified volume of the feeding liquid through the metering chamber, it is delivered to the shunt component under the action of the one-way component, and then flows into the specified storage tank. The metering process of the feeding liquid does not require a flow meter, solving the problem of high control cost.

[0021] II. Since the one-way component includes a pipe body and two support frames are formed inside the pipe body, and an elastic valve flap is installed on the support frame. When the feeding liquid enters the metering chamber from the feeding tank, the elastic valve flap close to the feeding tank is pushed open, and the elastic valve flap far from the feeding tank naturally closes. After the metering is completed, the elastic valve flap close to the feeding tank naturally closes, and the feeding liquid pushes open the elastic valve flap far from the feeding tank and flows into the shunt component, improving the metering accuracy of the feeding liquid;

[0022] III. Since a piston is arranged in the metering chamber, the piston is connected with a driving part, and the driving part drives the piston to reciprocate within a specified stroke, thereby metering a specified volume of feeding liquid and discharging it through the one-way component.

[0035] It should be noted that relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0036] The features and performance of the present utility model will be further described in detail below in conjunction with embodiments.

[0037] Embodiment:

[0038] Please refer to Figure 1 and Figure 2 , a feeding system, comprising:

[0039] A feeding tank 1 for storing a feeding liquid;

[0040] A one-way component 2 connected to the feeding tank 1;

[0041] A quantitative chamber 3 connected to the one-way component 2 and used to measure a specified volume of the feeding liquid;

[0042] A shunt component 4 connected to the one-way component 2;

[0043] A number of storage tanks connected to the shunt component 4.

[0044] In the existing feeding device, the opening and closing of the feed control valve are adjusted through a flow meter, and the control cost is relatively high. In this solution, after measuring a specified volume of the feeding liquid through the quantitative chamber 3, it is transported to the shunt component 4 under the action of the one-way component 2 and then flows into the specified storage tank. The quantitative process of the feeding liquid does not require a flow meter, thus solving the problem of relatively high control cost.

[0045] Refer to Figure 3, in order to prevent the feeding liquid in the metering chamber 3 from flowing back to the feeding tank 1, one feasible solution is as follows: the one-way component 2 includes a pipe body 21, and two support frames 22 are formed inside the pipe body 21. An elastic valve flap 23 is installed on the support frame 22. When this solution is adopted, when the feeding liquid enters the metering chamber 3 from the feeding tank 1, the elastic valve flap 23 close to the feeding tank 1 is pushed open, and the elastic valve flap far from the feeding tank 1 closes naturally. After the metering is completed, the elastic valve flap 23 close to the feeding tank 1 closes naturally, and the feeding liquid pushes open the elastic valve flap far from the feeding tank 1 and flows into the shunt component 4, improving the metering accuracy of the feeding liquid.

[0046] Refer to Figure 2 and Figure 4 , the metering structure of the metering chamber 3 is not uniquely limited in this solution. One feasible solution is as follows: a piston 31 is arranged in the metering chamber 3, and the piston 31 is connected with a driving part 32. When this solution is adopted, the driving part 32 drives the piston 31 to reciprocate within a specified stroke, thereby metering a specified volume of feeding liquid and discharging it through the one-way component 2.

[0047] The specific structure of the driving part 32 is not uniquely limited in this solution. One feasible solution is as follows: the driving part 32 includes an intermediate rod 321 connected to the piston 31. The intermediate rod 321 is rotatably connected with a rotating rod 322, and the rotating rod 322 is connected with a motor set 323. When this solution is adopted, the motor set 323 drives the rotating rod 322, the intermediate rod 321, and the piston 31 to move in sequence, and can convert the circular motion into a linear reciprocating motion.

[0048] Optionally, in this embodiment, the motor set 323 includes a motor and a transmission connected to the motor. The rotating rod 322 is connected to the low-speed shaft of the transmission.

[0049] Refer to Figure 5 , in order to adjust the stroke of the piston 31, one feasible solution is as follows: several adjustment holes 324 are formed on the rotating rod 322. By rotatably connecting the intermediate rod 321 to different adjustment holes 324, the stroke of the piston 31 can be adjusted conveniently and quickly.

[0050] Refer to Figure 6 , the specific structure of the shunt component 4 is not uniquely limited in this solution. One feasible solution is as follows: the shunt component 4 includes a delivery pipe 41 connected to the one-way component 2. A three-way valve 42 is arranged between the delivery pipe 41 and the storage tank. When this solution is adopted, by controlling the three-way valve 42, the flow direction of the feeding liquid can be controlled, so that the feeding liquid flows into the specified storage tank.

[0051] In order to solve the problem of high control costs, in this solution, after the metering chamber 3 measures a specified volume of the feeding liquid, it is transported to the flow splitting assembly 4 under the action of the one-way assembly 2 and then flows into the specified storage tank. The metering process of the feeding liquid does not require a flow meter, thus solving the problem of high control costs.

[0052] In order to improve the metering accuracy of the feeding liquid, in this solution, since the one-way assembly 2 includes a pipe body 21 and two support frames 22 are formed inside the pipe body 21, and an elastic valve flap 23 is installed on the support frame 22. When the feeding liquid enters the metering chamber 3 from the feeding tank 1, the elastic valve flap 23 close to the feeding tank 1 is pushed open, and the elastic valve flap far from the feeding tank 1 naturally closes. After the metering is completed, the elastic valve flap 23 close to the feeding tank 1 naturally closes, and the feeding liquid pushes open the elastic valve flap far from the feeding tank 1 and flows into the flow splitting assembly 4, improving the metering accuracy of the feeding liquid.

[0053] In order to facilitate the measurement of a specified volume of the feeding liquid, in this solution, since a piston 31 is arranged in the metering chamber 3, the piston 31 is connected with a driving part 32. The driving part 32 drives the piston 31 to reciprocate within a specified stroke, thereby measuring a specified volume of the feeding liquid and discharging it through the one-way assembly 2.

[0054] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
