Description

Technical Field

[0001] The utility model relates to a device for preparing plant seed gel balls, belonging to the technical field of biological restoration of organic polluted soil. Background Art

[0002] Sodium alginate and calcium ions are cross-linked through ionotropy to form a calcium alginate coating layer or capsule, thereby obtaining a stable and long-lasting film or microcapsule structure, which is a natural carrier in terms of carrier type.

[0003] In addition to physical and chemical properties, calcium alginate gel materials must also have excellent diffusion properties. Rich pores and large specific surface area can provide a high-quality environmental basis for plant seed germination, microbial fixation and culture, and pollutant adsorption.

[0004] At present, the preparation of calcium alginate gel is mainly carried out by dripping sodium alginate solution into calcium chloride solution through a syringe and a peristaltic pump. However, using the above method, on the one hand, only one calcium alginate gel can be prepared each time, the operation time is long, and the efficiency is low; on the other hand, seeds and sodium alginate solution with hemp fiber added are placed in the syringe, so the syringe is congested during the injection process, the processing time is long, and it is extremely inconvenient. Utility Model Content

[0005] The utility model provides a preparation device for plant seed gel balls, which solves the problems of long operation time caused by injecting sodium alginate into calcium chloride solution by using a syringe and a peristaltic pump, and congestion caused by seeds in the syringe and hemp fibers in the sodium alginate solution during the syringe injection process.

[0006] The technical problem to be solved by the utility model is achieved by adopting the following technical solutions:

[0007] A device for preparing plant seed gel balls comprises a bracket, a mixing tube is installed on the bracket, the top of the mixing tube is connected to a constant pressure dropping funnel for placing a sodium alginate solution, the other side wall of the mixing tube is connected to a Buchner funnel for placing a sodium alginate mixed solution, the side wall of the mixing tube is connected to a spiral injector through a branch pipe for placing plant seeds, the bottom of the mixing tube is connected to an elbow dropper for mixing a sodium alginate solution, a sodium alginate mixed solution and plant seeds, the bottom of the elbow dropper is connected to a beaker for placing a calcium chloride crosslinking agent, and sodium alginate solution-sodium alginate mixture solution-plant seeds are dripped into the beaker through the elbow dropper, and the sodium alginate and calcium chloride are chemically crosslinked to form calcium alginate gel to wrap the plant seeds and the mixture.

[0008] As a preferred example, the Buchner funnel is also connected to a peristaltic pump for passing the sodium alginate mixture solution into the mixing tube through the through hole of the Buchner funnel.

[0009] As a preferred example, the sodium alginate mixed solution refers to a solution formed by mixing a sodium alginate solution with powder or solid of not limited to hemp fiber and bentonite, and the particle size of the powder or solid is smaller than the through hole on the Buchner funnel, which is used to improve the structural mass transfer properties of the final calcium alginate gel spheres.

[0010] As a preferred example, the Buchner funnel, constant pressure dropping funnel and spiral injector are also fixed on the bracket.

[0011] As a preferred example, the constant pressure dropping funnel is further provided with a burette control valve, and the titration amount of the sodium alginate solution in the constant pressure dropping funnel is controlled by manually controlling the opening and closing of the burette control valve, so as to facilitate subsequent reactions.

[0012] As a preferred example, the constant pressure dropping funnel is provided with scale lines.

[0013] The above scheme is adopted to enable the operator to know the amount of the sodium alginate solution to be titrated by marking the scale line.

[0014] As a preferred example, the diameter of the branch tube is larger than the diameter of the plant seeds.

[0015] The above scheme is adopted to prevent the seeds from being blocked when flowing in the branch pipe due to the influence of the branch pipe diameter.

[0016] The beneficial effects of the utility model are:

[0017] (1) The utility model can add sodium alginate solution, sodium alginate mixed solution and plant seeds respectively through the device, and the spiral sampler is operated by grain;

[0018] (2) By controlling the effective mixing of materials and the success rate of cross-linking with calcium chloride through the device, seed gel balls can be quickly prepared, achieving the purpose of labor saving and mass production;

[0022] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific illustrations.

[0023] Compared with the preparation defects of calcium alginate gel balls in the background technology, the utility model adopts the following device to make calcium alginate gel balls, aiming to change the injection method of the syringe, thereby improving and shortening the operation time, and solving the congestion problem caused by the presence of seeds in the syringe and the hemp fibers in the sodium alginate solution.

[0024] like Figure 1 As shown, a preparation device of plant seed gel balls comprises a bracket, a mixing tube 8 is installed on the bracket, the top of the mixing tube 8 is connected to a constant pressure dropping funnel 1 with scale lines, which is used to place a sodium alginate solution, and a burette control valve 6 is provided on the constant pressure dropping funnel 1, and the other side wall of the mixing tube 8 is connected to a Buchner funnel 3, which is used to place a sodium alginate mixed solution (the sodium alginate mixed solution refers to a solution formed by mixing a sodium alginate solution with powder or solids not limited to hemp fiber and bentonite, and the sodium alginate mixed solution inside the Buchner funnel 3 is manually poured into the through hole in the Buchner funnel and flows into the mixing tube, and the particle size of the powder or solid is smaller than the through hole on the Buchner funnel 3, which is used to increase the final alginate solution). The side wall of the mixing tube 8 is connected to a spiral injector 2 through a branch pipe for placing plant seeds, and the diameter of the branch pipe is larger than the particle size of the plant seeds. The Büchner funnel 3, the constant pressure dropping funnel 1, and the spiral injector 2 are also fixed on the bracket 5. The lower part of the mixing tube 8 is connected to an elbow dropper 4, which is used to mix the sodium alginate solution, the sodium alginate mixed solution and the plant seeds. The lower part of the elbow dropper 4 is connected to a beaker 7 for placing a calcium chloride cross-linking agent, and the sodium alginate solution-sodium alginate mixture solution-plant seeds are added dropwise into the beaker 7 through the elbow dropper 4, and the sodium alginate and calcium chloride undergo a chemical cross-linking reaction to generate calcium alginate gel to wrap the plant seeds and the mixture.

[0025] The sodium alginate mixed solution is loaded into the Büchner funnel 3, the burette control valve 6 is manually adjusted, the screw on the spiral sampler 2 is turned, and the amount of seeds added is determined according to the dripping speed of the solution in the constant pressure dropping funnel 1. The flow rate of the sodium alginate solution and the interval time of the seeds falling match each other, and it is slowly dripped into the cross-linking agent to complete the preparation of calcium alginate-seed composite degradation bacteria gel balls. It should be noted that the optimal flow rate at which the sodium alginate solution is finally mixed and dripped into the cross-linking agent is based on the gel balling effect. If it is too fast, the gel will not form balls alone, and if it is too slow, the preparation efficiency will be affected. The flow rate is controlled by adding the sodium alginate mixed solution to the Büchner funnel 3 and the flow rate of adding the sodium alginate solution to the constant pressure dropping funnel.

[0026] As another example, the Buchner funnel 3 is also connected to a peristaltic pump for passing the sodium alginate mixture solution through the through hole of the Buchner funnel 3 into the mixing tube 8 .

[0027] The utility model can respectively add sodium alginate solution, sodium alginate mixed solution and plant seeds through the device, and the spiral sampler is operated by grains. The concentrations of the sodium alginate solution and the sodium alginate mixed solution are both 1-3%, and the concentration of the calcium chloride solution is 2-5%.

[0028] By controlling the effective mixing of materials and the success rate of cross-linking with calcium chloride through the device, seed gel balls can be quickly prepared to achieve the purpose of labor saving and mass production.

[0029] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
