Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of phosphate fertilizer processing equipment, in particular to a phosphate fertilizer packaging agent loading and conveying device. Background Art
[0002] In the process of phosphate fertilizer production, in order to prevent compound fertilizer from caking, absorbing moisture, forming dust and maintaining appearance consistency during storage and transportation, it is usually necessary to add a coating agent. This coating agent can not only effectively solve the above problems, but also achieve multiple purposes such as coloring, anti-caking and nutrient slow release. The coating agent is usually a high molecular polymer based on asphalt, which has the characteristics of high viscosity at room temperature and easy to clump.
[0003] However, it is precisely because of these physical properties of the coating that it faces a series of challenges in the production and transportation process. In particular, during the transportation process, due to the high viscosity and easy agglomeration of the coating, the reactor and the transportation pipeline need to be heated at high temperature, usually maintained at a temperature between 80°C and 100°C, to ensure that the material can flow smoothly.
[0004] Nevertheless, the existing design of the phosphate fertilizer coating loading and conveying device still has some shortcomings. In particular, after the loading is completed, the heating of the loading pipeline is usually stopped. At this time, due to the obstruction of the conveying pump (such as a high-temperature gear pump), the coating agent is easy to condense inside the loading pipeline. When loading is required again, the pipeline must be heated again to melt the condensed material inside. This process not only consumes a lot of time and energy, but also seriously reduces work efficiency and increases production costs. Utility Model Content
[0005] The utility model aims to provide a phosphate fertilizer coating loading and conveying device to solve the problem that the coating is easy to condense inside the loading pipeline due to the obstruction of the conveying pump. When loading is required again, the pipeline must be heated again to melt the condensed material inside. This process not only consumes a lot of time and energy, but also seriously reduces work efficiency and increases production costs.
[0006] To achieve the above-mentioned purpose, the utility model provides a phosphate fertilizer coating agent loading and conveying device, which is composed of a first straight pipe, a second straight pipe, a third straight pipe, a reflux inclined pipe, a first loading inclined pipe, a second loading inclined pipe, a third loading inclined pipe, a first valve, and a second valve. One end of the second straight pipe is connected to a reactor, one side of the first straight pipe is connected to the reflux inclined pipe through a three-way pipe, the outer end of the reflux inclined pipe is connected to the second straight pipe, and the bottom end of the second straight pipe is connected to the top of the reactor.
[0007] Preferably, a gear pump is connected to one side of the bottom of the reactor through a pipeline, the output end of the gear pump is connected to the first straight pipe, and the input end of the gear pump is connected to the reactor.
[0008] Preferably, a first valve is installed at the output end and the input end of the gear pump.
[0009] Preferably, a second valve is installed on the reflux inclined pipe.
[0010] Preferably, the top end of the first straight pipe is connected to the first loading inclined pipe, the top end of the first loading inclined pipe is connected to the second loading inclined pipe, the top end of the second loading inclined pipe is connected to the third loading inclined pipe, and one end of the third loading inclined pipe is connected to the third straight pipe.
[0011] Preferably, the bottom end of the third straight pipe is connected to a transport tank truck, and a sealing cover is installed at the bottom end of the third straight pipe. The sealing cover is covered at the feed port of the transport tank truck, and an annular sealing groove is arranged on the outer side of the bottom of the sealing cover, and a sealing ring is installed inside the sealing groove.
[0012] Preferably, the inclination angle of the first loading inclined tube is 80°, the inclination angle of the second loading inclined tube is 60°, and the inclination angle of the third loading inclined tube is 60°.
[0013] Preferably, the reflux inclined pipe includes a main body, one end of which is provided with an interface, which is plugged into and matched with an opening on one side of the tee pipe and connected by a tightening bolt, and the other end of the main body is provided with an elbow, and the outer end of the elbow is connected to the top end of the second straight pipe.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] In the phosphate fertilizer coating loading and conveying device, by introducing a reflux inclined pipe, it is ensured that after the loading is completed, the remaining coating in the pipeline can be quickly refluxed into the reactor, avoiding the long-term residence and condensation of the material in the pipeline. This design significantly reduces the residual amount of material in the pipeline, thereby reducing the risk of the material forming agglomerates inside the pipeline. Due to the ingenious setting of the loading inclined pipe and the reflux pipe, it is not necessary to preheat the pipeline for a long time to melt the condensed material when the loading operation is performed again. This greatly shortens the preparation time before loading and improves the overall work efficiency. By reducing the condensation of the material in the pipeline, the utility model reduces the heating time and temperature required for reloading, thereby significantly reducing steam consumption and energy consumption. This not only helps enterprises reduce production costs, but also meets the current environmental protection requirements of energy conservation and emission reduction. The loading inclined pipe is set in sections, especially the angle of the loading inclined pipe II is large, which is convenient for the reflux of materials. This design optimizes the pipeline layout, makes the flow of materials in the pipeline smoother, and further improves the efficiency of loading and reflux. The operation process of the utility model is simple and clear, and the switching between the loading mode and the reflux mode can be realized by simply controlling the switch state of the two valves. This design reduces the difficulty of operation and improves the usability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] The utility model provides a phosphate fertilizer packaging agent loading and conveying device, such as Figure 1-Figure 3 As shown, it is composed of a first straight pipe 5, a second straight pipe 4, a third straight pipe 11, a reflux inclined pipe 6, a first loading inclined pipe 8, a second loading inclined pipe 9, a third loading inclined pipe 10, a first valve 3, and a second valve 7. One end of the second straight pipe 4 is connected to the reactor 1, and one side of the first straight pipe 5 is connected to the reflux inclined pipe 6 through a three-way pipe 63. The outer end of the reflux inclined pipe 6 is connected to the second straight pipe 4, and the bottom end of the second straight pipe 4 is connected to the top of the reactor 1. One end of the second straight pipe 4 is connected to the reactor 1, so that the phosphate fertilizer encapsulating agent in the reactor can smoothly enter the pipeline system. The first straight pipe 5 plays an important role in the pipeline system. One side of it is connected to the reflux inclined pipe 6 through a three-way pipe 63. This design allows the encapsulating agent in the pipeline to flow back to the reactor 1 when necessary. The outer end of the reflux inclined pipe 6 is connected to the second straight pipe 4, which further enhances the efficiency and stability of the reflux. At the same time, the bottom end of the second straight tube 4 is connected to the top of the reactor 1 to form a complete loop, thereby ensuring the smooth implementation of the reflux operation.
[0023] In addition to the first straight pipe 5 and the return inclined pipe 6, the pipeline also includes a third straight pipe 11, a first loading inclined pipe 8, a second loading inclined pipe 9 and a third loading inclined pipe 10. These pipes work together to ensure that the phosphate fertilizer package can be efficiently transported to the transport tanker. The angles of each loading inclined pipe are carefully designed to ensure optimal fluidity and loading efficiency.
[0024] In this embodiment, a gear pump 2 is connected to one side of the bottom of the reactor 1 through a pipeline, the output end of the gear pump 2 is connected to the first straight pipe 5, and the input end of the gear pump 2 is connected to the reactor 1, so as to facilitate the transportation of materials.
[0025] Specifically, the output and input ends of the gear pump 2 are equipped with a first valve 3, and the reflux inclined pipe 6 is equipped with a second valve 7. These valves control and adjust the flow rate, thereby ensuring the stability and reliability of the entire loading and reflux process.
[0026] Furthermore, the top end of the first straight pipe 5 is connected to the first loading inclined pipe 8, the top end of the first loading inclined pipe 8 is connected to the second loading inclined pipe 9, the top end of the second loading inclined pipe 9 is connected to the third loading inclined pipe 10, and one end of the third loading inclined pipe 10 is connected to the third straight pipe 11.
[0027] Furthermore, the bottom end of the third straight pipe 11 is connected to the transport tank truck 12, and a sealing cover 111 is installed at the bottom end of the third straight pipe 11. The sealing cover 111 covers the feed port of the transport tank truck 12. An annular sealing groove 112 is arranged on the outer side of the bottom of the sealing cover 111, and a sealing ring 113 is installed inside the sealing groove 112 to ensure the sealing of the material when it enters the transport tank truck 12 and avoid splashing outward.
[0028] Furthermore, the inclination angle of the first loading inclined pipe 8 is 80°, the inclination angle of the second loading inclined pipe 9 is 60°, and the inclination angle of the third loading inclined pipe 10 is 60°, which is convenient for the transportation of materials.
[0029] Furthermore, the reflux inclined pipe 6 includes a main pipe body 61, one end of which is provided with an interface 62, which is plugged into an opening on one side of the three-way pipe 63 and connected by a tightening bolt 64, and the other end of the main pipe body 61 is provided with an elbow 65, the outer end of the elbow 65 is connected to the top end of the second straight pipe 4.
[0030] When the phosphate fertilizer package loading and conveying device of the utility model is used, the reactor 1 is first started to heat the phosphate fertilizer package to a state suitable for flow. Then, the gear pump 2 and the first valve 3 are opened to allow the package to enter the first straight pipe 5 through the suction effect of the gear pump 2. The strong conveying capacity of the gear pump 2 ensures that the package can flow through the pipeline system stably and continuously.
[0031] After passing through the first straight pipe 5, the coating agent is divided into the first loading inclined pipe 8, and then flows through the second loading inclined pipe 9 and the third loading inclined pipe 10 in sequence. The angles of these inclined pipes are precisely designed to ensure that the coating agent flows smoothly under the action of gravity to avoid blockage and accumulation. Finally, the coating agent enters the transport tanker 12 through the third straight pipe 11, completing the loading process.
[0032] During the loading process, if the loading operation needs to be paused or ended, the gear pump 2 and the first valve 3 can be closed, and the second valve 7 can be opened at the same time. At this time, the remaining encapsulating agent in the pipeline will flow back to the second straight pipe 4 through the reflux inclined pipe 6, and finally return to the reactor 1. This design not only avoids the encapsulating agent from staying in the pipeline for a long time and condensing, but also ensures the cleanliness of the pipeline system and the smooth progress of the next loading operation.
[0033] It is worth noting that the reflux inclined pipe 6 is connected to the first straight pipe 5 through a tee pipe 63. This connection method not only facilitates the control of the reflux operation, but also enhances the flexibility and stability of the pipeline system. At the same time, the main body 61 and the interface 62 of the reflux inclined pipe 6 are plug-fitted and connected through a clamping bolt 64. This connection method is both firm and easy to disassemble and repair.
[0034] In addition, a sealing device such as a sealing cover 111 and a sealing ring 113 is installed at the bottom end of the third straight pipe 11, ensuring good sealing performance at the feed port of the transport tank truck 12 during the loading process, thereby preventing the coating agent from splashing and leaking outward.
[0035] Finally, it should be noted that the electronic components in the gear pump 2 in this embodiment are all universal standard parts or parts known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components are connected by wires respectively, and the specific connection means should refer to the working sequence between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the art.

The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
