[0002] Liquid fertilizer production refers to the process of manufacturing liquid nutrients for plants to absorb and utilize. This fertilizer can contain the main nutrients (such as nitrogen, phosphorus, and potassium) and trace elements (such as iron, manganese, and zinc) required for plant growth. The electronic batching device for liquid fertilizer production is an industrial automation equipment system used to accurately and automatically control the proportion of various raw materials in the liquid fertilizer production process.

[0003] Currently, in the production process of liquid fertilizer, a batching system is required to mix the raw materials after proportioning them. The raw materials include nitrogen source solution, phosphorus source solution, potassium source solution, trace element solution, acid / alkali regulator, and water. Some of these raw materials (such as potassium source solution) are highly susceptible to temperature changes and are prone to crystallization, which can lead to blockages in the raw material conveying pipelines. This necessitates shutdown for cleaning, affecting the efficiency of raw material conveying and requiring improvement. Utility Model Content

[0004] The purpose of this invention is to provide an electronic batching system specifically for liquid fertilizer production, in order to solve the problem mentioned in the background art where raw materials are prone to crystallization and blockage of pipelines during the process of conveying and batching them.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electronic batching system for liquid fertilizer production, comprising a raw material storage tank, a liquid outlet pipe at the bottom of the raw material storage tank, a first electric valve on the liquid outlet pipe, a sleeve on the outer wall of the liquid outlet pipe, a heat tracing cable on the inner wall of the sleeve, a spare feed pipe and a main feed pipe on one end and one side of the liquid outlet pipe respectively, a second electric valve and a third electric valve on the spare feed pipe and the main feed pipe respectively, and a diversion component on one side of the sleeve;

[0006] The diversion assembly includes a diversion branch pipe, one side of which is connected to a compressed air input pipe. A first solenoid valve is installed on the compressed air input pipe. Multiple diversion branches are provided, and the multiple diversion branches are respectively connected to the liquid outlet pipe, the spare feed pipe and the main feed pipe.

[0007] Preferably, a second solenoid valve is provided on the branch pipe, and the connection between the branch pipe and the sleeve is sealed with thermal insulation material.

[0008] Preferably, a temperature sensor is installed on the inner wall of the sleeve, and multiple temperature sensors are provided.

[0009] Preferably, a drain pipe is provided at one end of both the spare feed pipe and the main feed pipe, and a drain valve is provided on the drain pipe.

[0010] Preferably, a limiting block is fixedly connected to the inner wall of one end of the branch pipe, and the limiting block is symmetrically distributed about the bisector of the branch pipe.

[0011] Preferably, the inner wall of the branch pipe is provided with a groove, and an anti-corrosion baffle is connected inside the groove by a shaft, and a filter screen is provided on one side of the anti-corrosion baffle.

[0012] Preferably, the anti-corrosion baffle is inclinedly connected to a support spring, and one end of the support spring is fixedly connected to the inner wall of the branch pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This device can avoid the blockage of the main feeding pipe, ensuring the efficiency of raw material transportation and thus improving the overall batching efficiency.

[0015] (2) This device uses a sleeve on the outer wall of the liquid outlet pipe to wrap the liquid outlet pipe, the main feed pipe and the backup feed pipe. The heat tracing material installed on the inner wall of the sleeve can heat the liquid outlet pipe, the main feed pipe and the backup feed pipe, so that the liquid outlet pipe, the main feed pipe and the backup feed pipe can maintain the temperature during the process of conveying raw materials and avoid the situation of excessively low temperature. This reduces the possibility of crystallization and blockage inside the liquid outlet pipe, the main feed pipe and the backup feed pipe.

[0016] (3) This device connects the main feed pipe and the backup feed pipe on one side of the liquid outlet pipe. The main feed pipe and the backup feed pipe can be used interchangeably. When the main feed pipe is being cleaned, the backup feed pipe can be used to transport raw materials. Thus, the main feed pipe is cleaned while the raw materials are transported normally, and the batching efficiency is improved. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-3 This utility model provides a technical solution: an electronic batching system for liquid fertilizer production, including a raw material storage tank 1, a liquid outlet pipe 2 at the bottom of the raw material storage tank 1, a first electric valve 10 on the liquid outlet pipe 2, a sleeve 8 on the outer wall of the liquid outlet pipe 2, a heating tape 9 on the inner wall of the sleeve 8, a spare feed pipe 13 and a main feed pipe 14 on one end and one side of the liquid outlet pipe 2 respectively, and a drain pipe with a drain valve at one end of both the spare feed pipe 13 and the main feed pipe 14. This structure can be found in the appendix to the specification. Figure 1As shown, impurities generated during cleaning can be discharged from the spare feed pipe 13 and the main feed pipe 14 via a drain pipe and a drain valve. A second electric valve 11 and a third electric valve 6 are respectively installed on the spare feed pipe 13 and the main feed pipe 14. A diversion assembly 5 is installed on one side of the sleeve 8. The handwheels and control components of the first electric valve 10, the second electric valve 11, and the third electric valve 6 pass through the sleeve 8 and are located outside the sleeve 8 to reduce the impact of temperature. The first electric valve 10, the second electric valve 11, and the third electric valve 6 are also controlled by a PLC, facilitating the switching of the spare feed pipe 13 and the main feed pipe 14 by switching the second electric valve 11 and the third electric valve 6. The diversion assembly 5 includes a diversion branch pipe 51, on which is installed... A second solenoid valve 7 is provided. The connection between the branch pipe 51 and the sleeve 8 is sealed with insulation material. This structure reduces heat loss and ensures the stability of the internal temperature of the sleeve 8. A temperature sensor 12 is installed on the inner wall of the sleeve 8. The temperature sensor 12 is electrically connected to the heating cable 9. Multiple temperature sensors 12 are provided. The temperature sensors 12 in this structure can be controlled by a PLC, which facilitates the temperature adjustment of the heating cable 9 and the control of the internal temperature of the sleeve 8. A compressed air input pipe 4 is connected to one side of the branch pipe 51. A first solenoid valve 3 is installed on the compressed air input pipe 4. Multiple branch pipes 51 are provided. A limit block 52 is fixedly connected to the inner wall of one end of the branch pipe 51. The limit block 52 is parallel to the branch pipe 51. The branch lines are symmetrically distributed vertically. This structure uses a limiting block 52 to limit the anti-corrosion baffle 54, ensuring that the anti-corrosion baffle 54 can only open outwards and cannot rotate inwards beyond the position limited by the limiting block 52. A groove is formed on the inner wall of the branch pipe 51, and the anti-corrosion baffle 54 is connected to the groove via a shaft. A filter screen 55 is installed on one side of the anti-corrosion baffle 54. This structure uses the filter screen 55 to intercept crystals and prevent blockage of the branch pipe 51. The surface of the anti-corrosion baffle 54 is coated with an anti-corrosion coating. The anti-corrosion baffle 54 not only seals the branch pipe 51 but also extends its service life. A support spring 53 is inclinedly connected to the end of the anti-corrosion baffle 54, and one end of the support spring 53 is fixedly connected to the inner wall of the branch pipe 51. This structure uses the support spring... Spring 53 supports the anti-corrosion baffle 54, maintaining a sealed and closed state for the branch pipes 51. This prevents impurities and raw materials from entering the branch pipes 51 from the outlet pipe 2, the backup feed pipe 13, and the main feed pipe 14. Multiple branch pipes 51 are connected to the outlet pipe 2, the backup feed pipe 13, and the main feed pipe 14 respectively. The first solenoid valve 3 enables automatic on / off control of the compressed air input pipe 4. The other side of the compressed air input pipe 4 is connected to an air compressor pump, facilitating the use of compressed air to clean the interior of the outlet pipe 2, the backup feed pipe 13, and the main feed pipe 14, preventing blockages. The first solenoid valve 3 and the second solenoid valve 7 are controlled by a PLC.One side of the spare feed pipe 13 and the main feed pipe 14 are connected to the main mixing tank for batching.

[0023] Working principle: When using this electronic batching system for liquid fertilizer production, the first electric valve 10 and the third electric valve 6 are first opened, allowing the raw material in the raw material storage tank 1 to enter the main feed pipe 14 from the liquid outlet pipe 2, and then be transported to the main mixing tank. During the transport process, the heating cable 9 heats the liquid outlet pipe 2 and the main feed pipe 14 to prevent the temperature of the liquid outlet pipe 2 and the main feed pipe 14 from being too low. If there are impurities or crystals remaining inside the main feed pipe 14, the third electric valve 6 can be closed and the second electric valve 11 can be opened, allowing the raw material to enter the standby feed pipe 13 through the liquid outlet pipe 2 for normal raw material input. Then, the first solenoid valve 3 and the second solenoid valve 7 are opened, and compressed air enters the branch pipe 51 to push the anti-corrosion baffle 54 outward and open it, allowing compressed air to smoothly enter the main feed pipe 14 to clean the main feed pipe 14, thereby preventing blockage inside the main feed pipe 14.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
