Description

Technical Field

[0001] This utility model relates to a fertilizer production device, specifically, to an automatic batching device for liquid water-soluble fertilizer. Background Technology

[0002] Liquid water-soluble fertilizer is a multi-element compound fertilizer that is completely soluble in water. It can precisely adjust the proportion of various nutrients according to the growth needs of different crops and soil conditions, and has the advantage of being more easily absorbed by plants. In the production of liquid water-soluble fertilizer, the various liquid raw materials need to be mixed according to the formula first, and then the mixture and solid raw materials are put into a reaction vessel. After the reaction is completed, it is discharged into the finished product tank for storage.

[0003] In traditional liquid raw material preparation, the liquid raw material is first poured into multiple mixing tanks, filtered, and then introduced into a mixing tank according to the formula. In order to control the ratio, a flow meter is usually installed on the conveying pipeline to measure the liquid raw material. However, this preparation method can only prepare a mixture of one formula at a time. When it is necessary to change the formula of liquid water-soluble fertilizer, the previous mixture must be drained and cleaned before a new mixture can be prepared, which affects the continuity of operation and the efficiency of liquid preparation.

[0004] In order to solve the above problems, people have been seeking an ideal technological solution. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic liquid water-soluble fertilizer dispensing device capable of simultaneously preparing mixtures of multiple different formulations, thereby improving the dispensing efficiency of multi-formulation mixtures.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic batching device for liquid water-soluble fertilizer, comprising three batching tanks and four mixing tanks. The bottom of each batching tank is connected to a main infusion pipe, and the output end of the main infusion pipe is connected to four branch infusion pipes. The four branch infusion pipes are connected one-to-one to the inlet of the four mixing tanks. Each branch infusion pipe is equipped with a solenoid valve and a flow meter.

[0007] Based on the above, each of the mixing tanks has a liquid collection pipe connected to the top of its outer wall, and the liquid inlet of the mixing tank is centrally located on the side wall of the liquid collection pipe.

[0008] Based on the above, each of the aforementioned infusion mains is equipped with a filter and an infusion pump.

[0009] Based on the above, it also includes an operation panel and a PLC controller. The operation panel is used to input control commands to the PLC controller. The PLC controller collects flow signals through each flow meter and controls the opening and closing of each solenoid valve and the liquid inlet pump.

[0010] Based on the above, the PLC controller model is Siemens S7-300.

[0011] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model has the following advantages:

[0012] (1) By setting up three mixing tanks to store one type of liquid raw material, each mixing tank can supply the liquid raw material to four mixing tanks through four infusion branches, thus simultaneously preparing four different liquid mixtures, thereby improving the liquid preparation efficiency.

[0013] (2) The liquid inlet on the mixing tank is concentrated on the liquid collection pipe. On the one hand, it is convenient to connect the pipeline in a centralized manner. On the other hand, when the mixing tank discharges liquid at the same time, various liquid raw materials can be pre-mixed on the liquid collection pipe so that the ratio of liquid in the tank and liquid discharged remains basically unchanged.

[0014] (3) The filter can filter impurities in the liquid raw materials to ensure the quality of the mixture; the PLC controller can realize the automatic operation of the whole batching device after the control instructions are set. Attached Figure Description

[0019] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0020] Example 1

[0021] like Figure 1 and Figure 2As shown, an automatic liquid water-soluble fertilizer dispensing device includes three dispensing tanks 1 and four mixing tanks 2. The bottom of each dispensing tank 1 is connected to a main inlet pipe 3. Each main inlet pipe 3 is equipped with a filter 8 and an inlet pump 9. The output end of the main inlet pipe 3 is connected to four branch inlet pipes 4. The four branch inlet pipes 4 are connected one-to-one to the inlet 21 of the four mixing tanks 2. Each branch inlet pipe 4 is equipped with a solenoid valve 5 and a flow meter 6 to control the pipeline opening and closing and monitor the liquid flow rate.

[0022] In practical use, a liquid raw material is poured into each mixing tank 1, and each mixing tank 2 corresponds to a different ratio of the mixture. After the liquid pump 9 is started, the liquid raw material is first filtered by the filter 8. Then, each liquid raw material is input into the four mixing tanks 2 through four infusion branches 4. The flow rate of each infusion branch 4 is monitored by the flow meter 6. Four different liquid mixtures can be prepared at the same time, thereby improving the liquid preparation efficiency.

[0023] In order to maintain a stable ratio when the liquid flows dynamically in the mixing tank 2, each of the mixing tanks 2 has a liquid collection pipe 7 connected to the top of its outer wall, and the liquid inlets 21 of the mixing tank 2 are concentrated on the side wall of the liquid collection pipe 7. When the mixing tank 2 discharges the mixed liquid to the downstream reactor, the various liquid raw materials can be pre-mixed on the liquid collection pipe 7 to avoid the situation where the liquid raw materials are not mixed in time when they first enter the mixing tank 2, resulting in different liquid ratios in the discharged liquid, so that the ratio of the liquid in the tank and the discharged liquid remains basically unchanged.

[0024] Example 2

[0025] like Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that the automatic batching device for liquid water-soluble fertilizer also includes an operation panel and a PLC controller. The PLC controller can specifically be a Siemens S7-300. The operation panel is used to input control commands to the PLC controller. The PLC controller collects flow signals through each flow meter 6 and controls the opening and closing of each solenoid valve 5 and the liquid inlet pump 9. After the control commands are set, the automatic operation of the entire batching device can be realized.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and not to limit it; although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solution of the utility model, they should all be included in the scope of the technical solution for which protection is requested in the utility model.
