Description

Technical Field

[0001] This utility model relates to the field of nutrient solution filling technology, specifically to a continuous nutrient solution filling device. Background Technology

[0002] In the existing technology, a conveyor belt is used to transport the filling bottles to one or more filling heads. Then, a pump injects the nutrient solution from the storage tank into the filling bottles, and a flow control valve controls the filling volume. After filling is completed, the conveyor belt removes the filled bottles and transports new filling bottles to the bottom of the filling head, thereby realizing continuous filling of nutrient solution.

[0003] Nutrient solutions contain various trace elements. During the storage process in the storage tank awaiting bottling, the differences in these components can easily cause stratification, resulting in inconsistent product composition across batches after bottling. While stirring the nutrient solution in the storage tank can reduce the risk of stratification, some components in the nutrient solution undergo chemical reactions during stirring, causing dissolved gases to escape and form bubbles. At the same time, the presence of large molecules such as proteins and polysaccharides in the nutrient solution increases the surface tension of the solution, making it difficult to eliminate bubbles. Consequently, these bubbles are filled into the bottling bottles, affecting the final filling accuracy and product quality.

[0004] Therefore, there is an urgent need for a continuous nutrient solution filling equipment to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a continuous nutrient solution filling device, comprising a base plate and a conveyor belt disposed on the base plate, wherein the conveyor belt is provided with a plurality of filling bottles, and further comprising a filling component disposed on the base plate for filling the filling bottles with nutrient solution.

[0006] The filling assembly includes a mounting frame fixedly connected to the base plate near the conveyor belt. The conveyor belt passes through the mounting frame. A storage tank is fixedly connected to the side of the mounting frame away from the base plate. The storage tank is filled with nutrient solution. The storage tank is connected to a delivery hose through a delivery assembly. The end of the delivery hose near the filling bottle is connected to multiple filling heads through a multi-port pipe. Each filling head has a flow control valve on its side wall. The mounting frame is equipped with a drive assembly for driving each filling head.

[0007] The delivery assembly includes an installation pipe fixedly connected to one side of the storage tank. A first infusion pipe is fixedly connected to one end of the installation pipe near the storage tank. The first infusion pipe is located near the bottom wall of the storage tank. A second infusion pipe is connected to the side of the installation pipe away from the conveyor belt via a connecting pipe. The second infusion pipe is located on the inner wall of the storage tank, and a suction pipe is fixedly connected to the end away from the installation pipe. A float is fixedly connected to the side wall of the suction pipe. The installation pipe is provided with a first mixing assembly for mixing the nutrient solution extracted by the first infusion pipe and the second infusion pipe.

[0008] A pump is installed at the end of the installation pipe away from the storage tank. The outlet end of the pump is connected to an operating pipe, which is connected to a delivery hose through a second mixing component.

[0009] The first mixing component includes a mesh plate fixedly connected to the inner wall of the mounting tube. The mesh plate is located at the junction of the first infusion tube and the outlet end of the second infusion tube. Multiple baffles are staggered on the inner wall of the mounting tube between the mesh plate and the pump.

[0010] The second mixing component includes a mixing pipe fixedly connected to the end of the operating pipe away from the pump. The end of the mixing pipe away from the operating pipe is connected to a delivery hose. A spiral plate is provided inside the mixing pipe, and a mixing groove is opened on the side of the spiral plate near the operating pipe.

[0011] The drive assembly includes two symmetrically arranged cylinders fixedly connected to the mounting frame on the side near the conveyor belt. The output ends of the two cylinders are connected to a drive plate, and the end of each filling head away from the conveyor belt is connected to the drive plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, through the design of the filling assembly, achieves continuous filling of nutrient solution while using a conveying assembly to separately extract the liquid from the bottom and top of the nutrient solution in the storage tank.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figures 1-4 The figure shows a continuous nutrient solution filling device, including a base plate 103 and a conveyor belt 101 disposed on the base plate 103. The conveyor belt 101 is provided with a plurality of filling bottles 102, and also includes a filling component disposed on the base plate 103 for filling the filling bottles 102 with nutrient solution.

[0022] The filling assembly includes a mounting frame 201 fixedly connected to the base plate 103 on the side near the conveyor belt 101. The conveyor belt 101 passes through the mounting frame 201. A storage tank 202 is fixedly connected to the side of the mounting frame 201 away from the base plate 103. The storage tank 202 is filled with nutrient solution. The storage tank 202 is connected to a conveying hose 203 through a conveying assembly. The end of the conveying hose 203 near the filling bottle 102 is connected to multiple filling heads 205 through a multi-port pipe 204. Each filling head 205 has a flow control valve 206 on its side wall. The mounting frame 201 is equipped with a drive assembly for driving each filling head 205.

[0023] It should be noted here that the continuous filling of nutrient solution is achieved through the configuration of the filling components.

[0024] Please see Figure 3 and Figure 4 The conveying assembly shown in the figure includes an installation pipe 401 fixedly connected to one side of the storage tank 202. A first infusion pipe 402 is fixedly connected to one end of the installation pipe 401 near the storage tank 202. The first infusion pipe 402 is located near the bottom wall of the storage tank 202. A second infusion pipe 403 (hose) is connected to the side of the installation pipe 401 away from the conveyor belt 101 through a connecting pipe. The second infusion pipe 403 is located on the inner wall of the storage tank 202, and a suction pipe 404 is fixedly connected to the end away from the installation pipe 401. A float plate 405 is fixedly connected to the side wall of the suction pipe 404. The installation pipe 401 is provided with a first mixing assembly for mixing the nutrient solution extracted by the first infusion pipe 402 and the second infusion pipe 403.

[0025] It should be noted that by setting up the conveying components, the liquid below and above the nutrient solution in the storage tank 202 is extracted separately, and the nutrient solution in different positions is mixed twice by the mixing action of the first mixing component and the second mixing component. This reduces the risk of inconsistent product composition in different batches after filling due to nutrient solution stratification, thereby improving the uniformity of nutrient solution composition in different filling bottles 102. At the same time, compared with the traditional stirring action, it can reduce the probability of air bubbles being generated in the nutrient solution, thereby improving the final filling and metering accuracy of the nutrient solution and the product quality.

[0026] Please see Figure 3 and Figure 4 In the figure, the end of the installation pipe 401 away from the storage tank 202 is equipped with a pump 406. The liquid outlet end of the pump 406 is connected to an operation pipe 407. The operation pipe 407 is connected to the delivery hose 203 through the second mixing assembly.

[0027] It should be noted here that pump 406 is used to extract nutrient solution from storage tank 202.

[0028] Please see Figure 3 and Figure 4 The first mixing component in the figure includes a mesh plate 501 fixedly connected to the inner wall of the mounting tube 401. The mesh plate 501 is located at the junction of the outlet ends of the first infusion tube 402 and the second infusion tube 403. Multiple baffles 502 are staggered on the inner wall of the mounting tube 401 between the mesh plate 501 and the pump 406.

[0029] It should be noted here that the first mixing component is used to perform the first mixing of the nutrient solution drawn from the storage tank 202.

[0030] Please see Figure 3 and Figure 4The second mixing component shown in the figure includes a mixing pipe 601 fixedly connected to the end of the operating pipe 407 away from the pump 406. The end of the mixing pipe 601 away from the operating pipe 407 is connected to the delivery hose 203. A spiral plate 602 is provided inside the mixing pipe 601. A mixing groove 603 is opened on the side of the spiral plate 602 near the operating pipe 407.

[0031] It should be noted here that the second mixing component is used to mix the nutrient solution drawn from the storage tank 202 a second time.

[0032] Working principle: When filling nutrient solution, multiple filling bottles 102 are first placed on the conveyor belt 101. Then, the conveyor belt 101 is used to move each filling bottle 102 to below the filling head 205. After the filling bottle 102 is moved to below the filling head 205, two cylinders 301 are activated to push the drive plate 302 closer to the filling bottle 102, thereby inserting the filling head 205 into the filling bottle 102.

[0033] After the filling head 205 is inserted into the filling bottle 102, the pump 406 at one end of the installation tube 401 is started. Under the suction action of the pump 406, the first infusion tube 402 is located at the bottom of the storage tank 202 and the extraction tube 404 is located above the nutrient solution under the buoyancy of the float plate 405. Thus, the lower and upper nutrient solutions in the storage tank 202 are extracted respectively. The extracted nutrient solution will flow into the installation tube 401 and be mixed for the first time under the separation action of the mesh plate 501 and the action of the staggered baffles 502.

[0034] After the first mixing, the nutrient solution, under the action of pump 406, continues to flow into mixing pipe 601. Under the spiral conveying action of mixing tank 603 on spiral plate 602, the nutrient solution is mixed again, thus achieving a second mixing of the nutrient solution. The nutrient solution mixed on both sides will flow from conveying hose 203 into multi-port pipe 204, and finally from each filling head 205 into filling bottle 102. The conveying components separately extract the liquid below and above the nutrient solution, and the mixing action of the first and second mixing components mixes the nutrient solution in different positions twice. This reduces the risk of inconsistent product composition in different batches after filling due to nutrient solution stratification, thereby improving the uniformity of nutrient solution composition in different filling bottles 102. At the same time, compared with traditional stirring, it can reduce the probability of air bubbles being generated in the nutrient solution, thereby improving the final filling metering accuracy and product quality of the nutrient solution.

[0035] After the synchronous filling of each filling bottle 102 is completed, the filled filling bottle 102 is removed by the conveyor belt 101, and a new filling bottle 102 is transported to the bottom of the filling head 205, thereby realizing the continuous filling of nutrient solution.

[0036] Example 2

[0037] Please see Figure 2 This embodiment further illustrates Example 1. The driving assembly shown in the figure includes two symmetrically arranged cylinders 301 fixedly connected to the mounting frame 201 on the side near the conveyor belt 101. The output ends of the two cylinders 301 are connected to a driving plate 302. The end of each filling head 205 away from the conveyor belt 101 is connected to the driving plate 302.

[0038] It should be noted here that the drive components are configured to move each filling head 205 closer to or further away from the filling bottle 102, thereby achieving the filling of nutrient solution and its subsequent movement away.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
