Description

Technical Field

[0001] This utility model relates to the field of fertilizer production equipment technology, specifically to an automated production equipment for producing peptide protein fertilizers containing organic matter, fish protein, polypeptides and biological polysaccharides. Background Technology

[0002] Peptide-protein fertilizer is a high-efficiency fertilizer rich in organic matter, fish protein, polypeptides, and polysaccharides. Existing peptide-protein fertilizer production processes typically involve multiple steps, including raw material mixing, enzymatic hydrolysis, and solid-liquid separation. Currently, equipment used for this type of fertilizer production often suffers from the following systemic deficiencies: 1. Reaction, conveying, and separation units are often set up as independent devices, relying on manual operation for material transfer and process switching, resulting in low production efficiency and poor batch stability. 2. To complete necessary auxiliary functions such as defoaming, pipeline unblocking, filtration and pressurization, and equipment cleaning, multiple independent air sources, water sources, and control systems are usually required, leading to a loose equipment layout, large footprint, and high energy and maintenance costs. 3. Viscous materials are prone to blockage during conveying, with a lack of effective preventative unblocking methods; solid-liquid separation efficiency is low; equipment cleaning is time-consuming and labor-intensive, affecting continuous production capacity.

[0003] In summary, existing technologies lack a compact production equipment that can highly integrate and intelligently coordinate the core production processes with key auxiliary functions. Utility Model Content

[0004] (a) Purpose of the utility model

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a peptide protein fertilizer production equipment with a high degree of automation, a continuous production process, convenient operation, and easy cleaning and maintenance.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A peptide protein fertilizer production equipment includes a chassis, inside which are arranged a reaction vessel, a solid-liquid separation unit, a fluid conveying unit, a pressure supply unit, and an electrical control unit;

[0009] The reactor has a feed inlet in the middle, an emulsifying homogenizer for shearing and dispersing materials inside the reactor, a weighing module at the bottom of the reactor, and an air inlet for connecting to a pressure supply unit on the reactor.

[0010] The discharge end of the reactor is connected in sequence to the gear pump in the fluid conveying unit and the solid-liquid separation unit through the first discharge pipe; the solid-liquid separation unit is provided with at least two discharge ports, which are used to output liquid fertilizer and solid slag respectively;

[0011] The pressure supply unit includes a plunger pump for providing gas pressure and a high-pressure pump for providing liquid pressure.

[0012] Specifically, the plunger pump is connected to the air inlet of the reactor via a first gas pipeline. A fifth solenoid valve is installed on the first gas pipeline to provide gas pressure to the reactor for defoaming or to assist in material discharge. The plunger pump is also connected to a second discharge pipe located between the gear pump outlet and the solid-liquid separation unit via a second gas pipeline. A second solenoid valve is installed on the second gas pipeline to ventilate and clear the gear pump and the first discharge pipe before material discharge. The plunger pump is also connected to the pressurization port of the solid-liquid separation unit via a third gas pipeline. A third solenoid valve is installed on the third gas pipeline to provide gas pressure to the solid-liquid separation unit to improve separation efficiency.

[0013] The high-pressure pump is connected to a cleaning spray device installed inside the reactor via a first water pipe. A sixth solenoid valve is installed on the first water pipe for cleaning the reactor. The high-pressure pump is also connected to the cleaning port of the solid-liquid separation unit via a second water pipe. A seventh solenoid valve is installed on the second water pipe for cleaning the solid-liquid separation unit.

[0014] The electrical control unit is a PLC control console, which is electrically connected to the weighing module, pressure monitoring element, emulsifying homogenizer, gear pump, plunger pump, high-pressure pump, solid-liquid separation unit, and solenoid valves on each pipeline. It is used to centrally control the start and stop of the equipment, set process parameters, and monitor the process according to a preset program.

[0015] Preferably, the solid-liquid separation unit is an electric scraper filter screen.

[0016] Preferably, the plunger pump is equipped with an air storage tank, and the high-pressure pump is a multi-stage pump equipped with a water storage tank.

[0017] Preferably, the first discharge pipe is provided with a first solenoid valve; the liquid outlet of the solid-liquid separation unit is connected to a third discharge pipe, and the third discharge pipe is provided with a fourth solenoid valve; the solid outlet of the solid-liquid separation unit is connected to a fourth discharge pipe, and the fourth discharge pipe is provided with an eighth solenoid valve.

[0018] Preferably, the gear pump is a rotor pump or cam rotor pump suitable for conveying high-viscosity slurries, such as existing models made of stainless steel. The high-pressure pump is a stainless steel multistage centrifugal pump, such as the CHL series lightweight multistage centrifugal pump, to meet the head and flow rate required for high-pressure cleaning. The plunger pump is an oil-free silent air compressor or miniature air pump to provide clean, dry compressed air. The electric scraper filter screen can be a vibrating screen or rotary vibrating screen with a geared motor and automatic scraper device, as is available in the prior art. The PLC control console can be an integrated controller with a touch screen, such as the Siemens S7-200 SMART series or Mitsubishi FX series. The solenoid valve is a normally closed two-position two-way solenoid valve, such as the corresponding model from SMC or Airtac, with an interface size matching the pipeline.

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] (1) By designing a plunger pump as a shared air source and connecting its air path to the reactor, discharge pipeline and solid-liquid separation device respectively, the integrated supply and reuse of the air source for the three key auxiliary functions of defoaming, unblocking and pressurized filtration are realized. At the same time, a high-pressure pump supplies the cleaning water source to the reactor and separation device separately. This design completes many essential functions with the simplest hardware configuration, greatly simplifies the equipment structure and reduces the equipment footprint and number of parts. (2) The equipment integrates the high-pressure cleaning water path as an inherent module inside the chassis and is laid out in parallel with the production pipeline. It can achieve efficient in-situ cleaning of the reactor and separation device without the need for an external complex cleaning system. This greatly simplifies the cleaning operation, reduces the maintenance difficulty and time cost, and ensures the cleanliness and continuous production capacity of the equipment. (3) The equipment forms a clear reaction, conveying, separation, pressure supply and cleaning module. This modular structure not only makes the equipment layout reasonable and easy to maintain, but also allows it to flexibly adapt to the production of peptide protein fertilizers with different formulations or physical properties (such as viscosity) by adjusting limited process parameters (such as pressure and timing), and has good process adaptability.

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.

[0026] The connection methods between the components involved in this utility model are all implemented using conventional methods in the relevant technical field. Specifically:

[0027] 1. Pipeline Connections: Each pipeline (such as discharge pipe, gas pipe, water pipe) and its corresponding component interface (such as pump inlet / outlet, reactor interface, valve interface, filter screen interface) are sealed and connected by threaded connections, flange connections, clamp connections, or quick-connect fittings to ensure the reliability and removability of the fluid channels. These connection methods and the required seals (such as O-rings and gaskets) are all known technologies in the field. 2. Circuit Connections: The control signal lines and power lines between the PLC control console (9) and each electrical component (such as weighing module, pressure monitoring element, motor, solenoid valve) are connected by standard industrial terminals or cable connectors and run through cable trays or conduits inside the chassis (1). These electrical connection methods comply with industrial electrical installation specifications and are existing technologies.

[0028] The details of the above-mentioned conventional connection methods are well known to those skilled in the art. Therefore, the following will focus on the detailed description of the connection relationship, layout and overall control logic between the functional units of this utility model, in conjunction with the accompanying drawings.

[0029] like Figure 1 and Figure 2As shown, this utility model provides a peptide protein fertilizer production equipment, including a casing 1 and a reaction vessel 3. The reaction vessel 3 is fixed inside the casing 1. A weighing module 2 is installed at the bottom of the reaction vessel 3, and a pressure monitoring element and an air inlet are installed at the top of the reaction vessel for accurately monitoring the feed rate and the pressure inside the reaction vessel. A feed inlet 27 is provided in the middle of the reaction vessel 3, which is connected to a feeding port 28 provided on the casing for feeding raw materials and enzyme preparations, etc.

[0030] The reactor 3 is equipped with a high-speed emulsifying homogenizer 4, which is used to fully shear, homogenize, and stir the materials. The discharge port at the bottom of the reactor 3 is connected to the inlet of the gear pump 7 through a first discharge pipe 18. A first solenoid valve 10 is installed on the first discharge pipe 18.

[0031] The material conveying unit includes a gear pump 7 connected to the first discharge pipe 18. The discharge port of the gear pump 7 is connected to the inlet of the solid-liquid separation unit via a second discharge pipe 19. The gear pump 7 is used to convey viscous slurry materials. In this embodiment, the gear pump 7 can be a stainless steel cam rotor pump from the prior art, such as the NETZSCH NEMO® series or BORGER rotor pump, which has good self-priming capability and the ability to convey high-viscosity media containing solid particles.

[0032] The solid-liquid separation unit includes an electrically operated scraper-type filter screen 8, which has a liquid outlet and a solid outlet. The liquid outlet is connected to a third discharge pipe 20, and the solid outlet is connected to a fourth discharge pipe 21. A fourth solenoid valve 13 is installed on the third discharge pipe 20 to control the discharge of liquid fertilizer; an eighth solenoid valve 17 is installed on the fourth discharge pipe 21 to control the discharge of solid residue. In this embodiment, the filter screen 8 can be a stainless steel electrically operated scraper-type vibrating screen, with a screen mesh size selectable according to product requirements (e.g., 80-200 mesh), and equipped with a geared motor to drive the scraper for automatic cleaning of the screen surface.

[0033] The pressure supply unit includes a plunger pump 5 with an air tank and a multi-stage high-pressure pump 6 with a water tank. The plunger pump 5 can use an oil-free, silent air compressor (such as a small air compressor of the corresponding model from Leybold or Kobelco) as the pressure source. The high-pressure pump 6 can use a stainless steel multi-stage centrifugal pump (such as a Grundfos CR series or New World CHL series), with an outlet pressure exceeding 2.0 MPa, meeting the requirements for high-pressure cleaning.

[0034] The outlet of the plunger pump 5 is connected to the air inlet at the top of the reactor 3 through the first air passage pipe 22. The first air passage pipe 22 is equipped with a fifth solenoid valve 14, which is used to provide gas pressure to the reactor 3 for defoaming or to assist in material discharge.

[0035] The air outlet of the plunger pump 5 is connected to the second discharge pipe 19 through the second air passage pipe 23. The second air passage pipe 23 is equipped with a second solenoid valve 11, which is used to ventilate and clear the second discharge pipe 19 and the upstream pipe before discharge to prevent blockage.

[0036] The outlet of the plunger pump 5 is connected to the pressure port of the filter screen 8 through the third air passage pipe 24. The third air passage pipe 24 is equipped with a third solenoid valve 12, which is used to provide positive pressure to the filter screen 8 cavity during filtration to improve filtration efficiency.

[0037] The outlet of the high-pressure pump 6 is connected to the inlet of the annular cleaning spray device 29 at the top of the reactor 3 via the first water pipe 25. The first water pipe 25 is equipped with a sixth solenoid valve 15 for high-pressure cleaning of the inside of the reactor 3.

[0038] The outlet of the high-pressure pump 6 is also connected to the cleaning inlet of the filter screen 8 through the second water pipe 26. The second water pipe 26 is equipped with a seventh solenoid valve 16 for high-pressure cleaning of the filter screen 8.

[0039] The electrical control unit includes a PLC control console 9 installed outside the chassis 1. The input ports of the PLC control console 9 are connected to the weighing module 2 and the pressure monitoring element on top of the reactor 3 to receive weight and pressure signals. Its output control ports are connected via electrical circuits to the drive motors of the emulsifying homogenizer 4, gear pump 7, plunger pump 5, high-pressure pump 6, filter screen 8, scraper actuator, and all solenoid valves (first solenoid valve 10 to eighth solenoid valve 17). The PLC control console 9 has a pre-installed automated control program that can automatically execute logical judgments and output control commands based on input signals and preset process parameters (such as weight threshold, time T1 / T2, pressure threshold P1 / P2 / P3, pulse period, etc.), achieving centralized automated control of the entire equipment's start-up and shutdown, process sequence, parameter adjustment, and status monitoring.

[0040] In this embodiment, the PLC control console 9 can be an integrated touch screen PLC, such as a Siemens KTP series screen integrated with an S7-200 SMART PLC, or a Delta DOP series touch screen combined with a DVP series PLC.

[0041] The pressure monitoring element (30) used to monitor the internal pressure of the reactor (3) can be a pressure transmitter from the prior art. For example, a Honeywell HSC series diffused silicon pressure transmitter or a Weidmüller PRO-M series pressure transmitter can be selected. The transmitter is installed on the gas inlet bypass or dedicated pressure measuring port on the top of the reactor via a threaded interface, and its output 4-20mA standard signal is connected to the analog input port of the PLC control console 9.

[0042] For each solenoid valve 10-17, you can choose a normally closed two-position two-way stainless steel solenoid valve from SMC or Airtac (such as the SMC VX21 series).

[0043] The automatic control process of this utility model is executed by the PLC control console 9, and its main steps are as follows:

[0044] S1: Feeding and Homogenization: The operator feeds raw materials through the feeding port 28, and the weighing module 2 monitors the weight in real time; when the PLC control console 9 determines that the feeding amount has reached the preset value based on the weighing signal, it will automatically stop or prompt to stop feeding, and the next process can be entered on the control screen.

[0045] S2: Enzymatic hydrolysis and pressure management: After homogenization, the PLC control panel will prompt the operator to add the appropriate proportion of enzyme preparations and other excipients, start the enzymatic hydrolysis reaction, and start timing T2. During the reaction, if the PLC control panel 9 determines that the pressure value is lower than the set threshold P1 based on the signal fed back by the pressure monitoring element (30), indicating that foam has increased, the PLC will control the opening of the fifth solenoid valve 14 and the plunger pump 5 to introduce gas into the reactor to pressurize and defoam until the pressure is restored to the set value P2 and then closed.

[0046] S3: Discharge preparation and pipeline clearing: After the enzymatic hydrolysis time T2 ends, the PLC control console 9 first opens the second solenoid valve 11 and starts the plunger pump 5. In a pulse manner (for example, turn on for 2 seconds, turn off for 1 second, and cycle 3 times), the gas is injected into the second discharge pipe 19 through the second gas pipe 23, and flows back through the gear pump 7 cavity and into the first discharge pipe 18. This clears the entire discharge pipeline from the gear pump 7 and its upstream to the bottom of the reactor 3 to prevent viscous materials from clogging it.

[0047] S4: Pressurized Solid-Liquid Separation: After pipeline dredging is completed, PLC control panel 9 sequentially opens the first solenoid valve 10, starts the gear pump 7, and opens the fourth solenoid valve 13 to pump the slurry into the filter screen 8. Simultaneously, PLC control panel 9 opens the third solenoid valve 12 and starts the plunger pump 5, continuously supplying gas at a constant pressure P3 through the third gas pipe 24 to the top of the sealed cavity of the filter screen 8, creating a pressure difference on both sides of the filter screen, thereby accelerating the liquid's passage through the filter screen and improving separation efficiency. During filtration, the scraper of the filter screen 8 operates automatically according to a preset interval or motor load feedback to prevent filter screen clogging. Liquid fertilizer is discharged through the third discharge pipe 20, and solid slag is discharged through the fourth discharge pipe 21.

[0048] S5: Automatic Cleaning: After a production batch is completed, the cleaning program can be started. The PLC control panel 9 first closes the first, second, third, fourth, fifth, and eighth solenoid valves (10, 11, 12, 13, 14, 17), stopping all material and air supply. Then, it opens the sixth solenoid valve 15 and the seventh solenoid valve 16, and starts the high-pressure pump 6. High-pressure water is supplied in two paths: one path is delivered via the first water pipe 25 to the annular cleaning spray device 29 at the top of the reactor 3, forming an umbrella-shaped water curtain to flush the inner wall of the reactor and the emulsifying homogenizer 4; the other path is delivered via the second water pipe 26 to the cleaning port of the filter screen 8, where high-pressure backwashing removes solid residue trapped by the filter screen. The cleaned wastewater can be discharged separately or mixed through the third discharge pipe 20 and the fourth discharge pipe 21.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
