Description

Technical Field

[0001] This utility model relates to the technical field of vegetable oil fermentation tank equipment, and in particular to an almond vegetable oil fermentation tank with pressure-type liquid level detection. Background Technology

[0002] Almonds, also known as almond kernels or almond nut, are the dried fruit of plants in the genus *Amyda* of the Rosaceae family. They are a very important tree species used for dried fruit, oil, and medicinal purposes. The world's annual production is around 1.2 million tons, ranking first among the world's four major dried fruits. In the 1970s, when American almonds were exported to my country, they were mistakenly translated as "American almonds" and this misinterpretation became widespread. Almonds are rich in protein, vitamin E, and dietary fiber, and are usually processed into almond oil for widespread market distribution.

[0003] In the production and processing of almond oil, fermentation is typically performed in large fermentation tanks to improve the quality and taste. In existing fermentation processes, after fermentation of a tank of almond oil, half the oil is usually dispensed, leaving the remaining half in the fermentation tank. Then, the remaining half is added and mixed for further fermentation. This process significantly improves fermentation efficiency. However, this process requires precise monitoring of the amount of oil dispensed and added to the fermentation tank, especially for large tanks. Existing large tanks equipped with level detection, such as filling machines with level monitoring functions, are suitable for this purpose. (Patent No.: CN202323033135.1) The key technical points of this invention include a filling tank, a liquid level detection device, an alarm device, a timing module, a first electrically controlled valve, and a controller. The filling tank is equipped with a first electrically controlled valve installed at the liquid inlet. The liquid level detection device is used to detect the liquid level height inside the filling tank. When the liquid level in the filling tank is lower than the minimum filling line, the first electrically controlled valve and the timing module are triggered. Before the end of the replenishment period, when the liquid level in the filling tank reaches the minimum filling line, the timing module is turned off. When the liquid level in the filling tank reaches the maximum filling line, the first electrically controlled valve is turned off. After the replenishment period ends, if the liquid level in the filling tank still has not reached the minimum filling line, the alarm device is triggered. This invention can provide timely alarms when the liquid level is difficult to reach the minimum filling line after replenishment in a normal pressure filling machine, so that personnel can promptly send residual liquid from the upstream process into the filling tank before the filling is completed, avoiding secondary filling and reducing production losses.

[0004] Existing tank level detection structures that use a float to detect liquid levels can cause the liquid level to fluctuate during operation, especially for large tanks with larger and faster inflow and outflow rates. This fluctuation can lead to inaccuracies in the liquid level detection data. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing tank level detection structure that detects liquid level by means of a float structure is prone to deviation in liquid level detection data because the float can float with changes in liquid level. This is because the liquid level inside the tank will sway when liquid is added or removed during operation.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: an almond oil fermentation tank with pressure-type liquid level detection, comprising a fermentation tank body, four support bosses on the outer wall of the fermentation tank body, a top cover on the top of the fermentation tank body, and a bottom tank at the bottom of the fermentation tank body. An inlet pipe is connected to the side wall of the bottom tank, the inlet pipe extending into the bottom tank with its outlet facing upwards. A perforated plate is provided inside the bottom tank above the outlet of the inlet pipe, the perforated plate having a circular cross-section and its outer wall fixed to the inner wall of the bottom tank. A baffle is provided in the middle of the perforated plate directly above the outlet of the inlet pipe, the baffle having a circular cross-section and a straight... The diameter is larger than the outlet diameter of the inlet pipe. A liquid outlet pipe is connected to the bottom of the bottom tank. A mesh ball is provided at the bottom of the bottom tank where it connects to the liquid outlet pipe. A motor is provided on the top of the top cover. The bottom of the motor drives a stirring paddle that penetrates the top cover and extends into the fermentation tank. A receiving platform is provided in the middle of the lower part of the fermentation tank. The receiving platform is supported and fixed by four support shafts connected to the inner wall of the fermentation tank. A pressure sensor is provided on the receiving platform. A main controller is provided on the upper part of the outer wall of the fermentation tank. The main controller is provided with a display panel with a digital display. The main controller and the pressure sensor are connected by a wire signal connection.

[0007] Preferably, a lead wire plate is provided at the bottom of the pressure sensor for signal connection, and the lead wire plate is connected to a wire. The lead wire plate and the pressure sensor are in signal communication, and the lead wire plate can be connected to the wire via a terminal block structure.

[0008] Preferably, the top of the receiving platform is recessed to form an inner groove, the longitudinal section of the inner groove is cross-shaped, two through grooves are opened at the upper part of the inner groove, and two limiting grooves are opened at the bottom of the inner groove.

[0009] Preferably, the line connecting the two through slots is perpendicular to the line connecting the two limiting slots.

[0010] Preferably, the lower part of the side wall of the guide plate is provided with two opposing locking blocks. The two locking blocks on the guide plate are aligned with the two through slots and inserted so that the guide plate is located in the middle of the inner slot. After rotating the guide plate 90 degrees, it is lowered so that the locking blocks engage in the limiting slots. Through the above structure and installation method, not only is the installation and disassembly of the pressure sensor convenient, but it also avoids generating other forces on the pressure sensor that could affect the stability of the monitoring and the accuracy of the data.

[0011] Preferably, the diameter of the guide plate is the same as the diameter of the inner groove, and the dimensions of the locking block, the through groove, and the limiting groove are the same.

[0012] Preferably, a liquid level sensor is provided on the upper part of the inner wall of the fermentation tank, and the liquid level sensor is connected to the main controller via a wire.

[0013] Preferably, the display panel has two indicator lights located above the digital display.

[0014] Preferably, the top edge of the top cover is provided with two oppositely arranged lifting lugs.

[0015] Preferably, the main controller is a controller that integrates a signal receiver, a signal processor, and a circuit board.

[0016] The present invention adopts the above technical solution and has the following technical effects compared with the prior art:

[0017] (1) By installing a pressure sensor in the fermenter and setting a receiving platform to limit the installation of the pressure sensor, the pressure sensor can stably sense and monitor the water pressure at a fixed position at the bottom of the fermenter. Then, by setting a perforated plate, baffle and perforated ball, the liquid flow force during liquid inlet and outlet can be reduced, thereby improving the stability of pressure sensing and ensuring the accuracy of liquid level monitoring data in the fermenter.

[0018] (2) By setting up structures such as inner groove, through groove, limit groove and card block, it is not only convenient to install and disassemble the pressure sensor, but also the structure of the receiving platform will not exert other forces on the pressure sensor when the pressure sensor is installed on the receiving platform, thus affecting the stability of monitoring and the accuracy of data.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Example 1:

[0031] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6The fermentation tank 1 has four support bosses 5 on its outer wall. A top cover 2 is located on the top of the fermentation tank 1, and a bottom tank 7 is located at the bottom. An inlet pipe 6 is connected to the side wall of the bottom tank 7, extending into the bottom tank 7 with its outlet facing upwards. A perforated plate 20 is located inside the bottom tank 7 above the outlet of the inlet pipe 6. The perforated plate 20 has a circular cross-section, and its outer wall is fixed to the inner wall of the bottom tank 7. A baffle 19 is located in the middle of the perforated plate 20, directly above the outlet of the inlet pipe 6. The baffle 19 has a circular cross-section, and its diameter is larger than the outlet diameter of the inlet pipe 6. An outlet pipe 8 is connected to the bottom of the bottom tank 7. A perforated ball 801 is located at the connection point between the bottom of the bottom tank 7 and the outlet pipe 8. Both the inlet pipe 6 and the outlet pipe 8 are connected to the bottom tank. The 7-way connection ensures that both the inlet and outlet are below the pressure sensor 12. During inlet, the baffle 19 blocks the incoming liquid from spreading outwards, and the mesh plate 20 further disperses the liquid. Combined with the mesh ball 801 dispersing and collecting the outgoing liquid during outlet, the impact of liquid flow on the pressure sensor 12 during inlet and outlet is minimized. Two opposing lifting lugs 4 are located at the top edge of the top cover 2, facilitating the lifting of the top cover 2 by an external lifting mechanism for cleaning and maintenance of the fermentation tank 1. A motor 3 is located at the top of the top cover 2, with a driving mechanism at the bottom of the motor 3 connecting to a stirring paddle 9 that penetrates the top cover 2 and extends into the fermentation tank 1. The stirring paddle 9 primarily agitates the liquid inside the fermentation tank 1. The liquid level is uniformly diffused. It can be set to not operate during continuous feeding or discharging, thus not affecting the pressure sensor 12's sensing of liquid level changes during feeding or discharging. A receiving platform 10 is located in the lower middle of the fermentation tank 1. The receiving platform 10 is supported and fixed by four support shafts 11 connected to the inner wall of the fermentation tank 1. A pressure sensor 12 is installed on the receiving platform 10. During installation, the pressure sensor 12 must be installed with the pressure-bearing element facing upwards. A lead wire plate 17 is connected to the bottom of the pressure sensor 12 for signal connection. A main controller 13 is located on the upper part of the outer wall of the fermentation tank 1. The main controller 13 is a controller integrating a signal receiver, signal processor, and circuit board. A display panel 14 is installed on the main controller 13. A digital display 1401 is provided. The main controller 13 and the pressure sensor 12 are connected by a wire 16. The wire board 17 can be connected to the wire 16 through a terminal block structure. Both the wire board 17 and the pressure sensor 12 are waterproof. A hidden groove for threading the wire 16 can be set in the inner wall of the fermentation tank 1 and in the support shaft 11. During the liquid inlet or outlet process, the hydraulic pressure on the pressure sensor 12 will change due to the change in liquid level. By setting the calculation relationship and variable relationship of liquid level height, pressure value, liquid density and local gravity value in advance in the main controller 13, the change relationship of liquid level height is displayed by the change of pressure value, and the liquid level height data is displayed by the digital display 1401 on the display panel 14.

[0032] Example 2:

[0033] refer to Figure 5 The top of the receiving platform 10 is recessed to form an inner groove 18. The longitudinal section of the inner groove 18 is cross-shaped. Two through grooves 1801 are opened at the upper part of the inner groove 18, and two limiting grooves 1802 are opened at the bottom of the inner groove 18, with the line connecting the two through grooves 1801 and the line connecting the two limiting grooves 1802 perpendicular to each other. Two locking blocks 1701 are provided at the lower part of the side wall of the guide plate 17, with the diameter of the guide plate 17 being the same as the diameter of the small groove of the inner groove 18. The locking blocks 1701, the through grooves 1801, and the limiting grooves 1802 are connected. The dimensions are the same; when it is necessary to place the pressure sensor 12 into the receiving platform 10, align the two locking blocks 1701 on the guide plate 17 with the two through slots 1801 and insert them so that the guide plate 17 is located in the middle of the inner slot 18. Then rotate the guide plate 17 90 degrees and put it down so that the locking blocks 1701 are engaged in the limiting slot 1802. Through the above structure and installation method, it is not only convenient to install and disassemble the pressure sensor 12, but also will not generate other forces on the pressure sensor 12, thus affecting the stability of monitoring and the accuracy of data.

[0034] Example 3:

[0035] refer to Figure 4 , Figure 6 A liquid level sensor 15 is installed on the upper part of the inner wall of the fermentation tank 1. The liquid level sensor 15 is connected to the main controller 13 via a wire 16. Two indicator lights 1402 are installed on the display panel 14 above the digital display 1401. One of the two indicator lights 1402 shows a red light to indicate an over-liquid level alarm, and the other shows a green light to indicate normal operation. When the liquid level in the fermentation tank 1 reaches the liquid level sensor 15, the liquid level sensor 15 transmits the sensing signal to the main controller 13. After receiving the signal, the main controller 13 makes a judgment by the signal processor and displays it through the red indicator light. This serves as a foolproof measure to prevent the liquid in the fermentation tank 1 from overflowing.
