Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural production technology, and in particular to a fruit preservation liquid concentration detection and adjustment device. Background Technology
[0002] Fruits are juicy, edible plant fruits with a predominantly sweet and sour taste. Fruits are not only rich in vitamins and nutrients but also promote digestion. Preservative solutions are needed for fruit storage, and these solutions require preparation before use.
[0003] The existing methods for preparing preservation solutions generally involve using a preservation solution tank. First, the preservation agent is added to the tank. Then, the stock solution is continuously added to dilute the preservation agent. The concentration of the preservation solution is continuously diluted and manually monitored until a suitable concentration is reached.
[0004] However, the above-mentioned method of preparing the preservative solution requires manual addition of materials and liquid and testing of the concentration of the preservative solution, which consumes a lot of manpower and resources and has low efficiency. Therefore, there is room for improvement. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a fruit preservative solution concentration detection and adjustment device. Its advantages include automatic preservative solution preparation, saving manpower and resources, and improving preparation efficiency.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A fruit preservation liquid concentration detection and adjustment device includes a mixing table. The top of the mixing table is provided with a stock solution tank and a preservation liquid tank. An installation plate is provided between the stock solution tank and the preservation liquid tank. A water pump is provided on the top of the installation plate. A water pump pipe is provided at the input end of the water pump and extends into the stock solution tank. The output end of the water pump is connected to a water outlet pipe, which is located above the preservation liquid tank.
[0008] A lifting mechanism is provided on one side of the top of the mixing table. The mixing table is connected to a lifting plate through the lifting mechanism. A digital display controller is provided on the top of the lifting plate. A concentration detector is provided on the side wall of the lifting plate. The input end of the concentration detector is connected to a concentration detection probe through a detection line. The output end of the concentration detector is connected to the digital display controller.
[0009] The above technical solution involves the following steps: First, preservatives are added to the preservation solution tank. A water pump is then used to draw raw liquid from the original solution tank and dilute the preservatives in the preservation solution tank. Simultaneously, a lifting mechanism is activated, causing the lifting plate to move downwards. A concentration detection probe is then inserted into the preservation solution tank. The detector measures the resistance between two probe electrodes to determine the solution's conductivity, thereby determining the preservation solution concentration. This value is transmitted to the controller. When the concentration is below a preset value, the controller activates the water pump to deliver the raw liquid to the preservation solution tank. The pump stops when the concentration reaches the preset value. This automatic preparation of the preservation solution saves manpower and resources and improves preparation efficiency.
[0010] The present invention is further configured such that the lifting mechanism includes a column, a motor is provided at the top of the column, the output shaft of the motor is connected to a lead screw, a slider is provided on the outer wall of the lead screw, and the slider is connected to the lifting plate.
[0011] The above technical solution controls the motor to drive the lead screw to rotate, which in turn drives the slider to move, thereby enabling the lifting plate to move up and down. This facilitates the entry of the concentration detection probe into the preservation liquid at different levels, improving the ease of operation.
[0012] The present invention is further configured such that a groove is provided on the outer wall of the column, and the slider can slide within the groove.
[0013] Through the above technical solutions, the slider can slide within the groove when the lifting plate moves, thus improving the stability of the lifting plate's movement.
[0014] The present invention is further configured such that an air pump is provided at the bottom of the mixing table, and a stirring assembly is connected to the output end of the air pump, the stirring assembly being located at the bottom of the preservation liquid tank.
[0015] The above technical solution controls the air pump to drive the stirring component to blow air. When the stirring component blows air, it stirs the preservative liquid in the preservative liquid tank, thereby improving the uniformity of the preservative liquid mixing.
[0016] The present invention is further configured such that the stirring assembly includes an air blowing plate, and a plurality of air blowing pipes are provided at equal intervals at the top edge of the air blowing plate, and the air blowing pipes are inclined.
[0017] The above technical solution involves setting up an air blowing pipe, which increases the air blowing contact area between the preservative liquid and the air blowing plate, thereby improving the mixing effect of the preservative liquid.
[0018] The present invention is further configured such that the surface of the air blowing pipe is provided with a plurality of air blowing heads distributed at equal intervals, and the air blowing heads are connected to the air blowing pipe.
[0019] The above technical solution involves setting up an air blowing head, which increases the contact area between the preservative liquid and the air blowing plate, further improving the mixing effect of the preservative liquid and air.
[0020] The present invention is further configured such that the air blowing plate, air blowing pipe and air blowing head are all made of stainless steel.
[0021] Through the above technical solutions, the air blowing plate, air blowing pipe and air blowing head made of stainless steel have good corrosion resistance, which improves the service life of the stirring components.
[0022] The beneficial effects of this utility model are as follows: When using this fruit preservative solution concentration detection and adjustment device, firstly, preservative agents are added to the preservative solution tank. Then, a water pump is controlled to draw raw liquid from the original solution tank and dilute the preservative agents in the preservative solution tank. The lifting mechanism is then controlled, and the lifting plate moves downwards, allowing the concentration detection probe to enter the preservative solution tank. The concentration detector determines the conductivity of the solution by measuring the resistance between the two probe electrodes, thereby determining the preservative solution concentration value, which is transmitted to the controller. When the concentration value is lower than the preset value, the controller starts the water pump to deliver the raw liquid to the preservative solution tank. When the concentration reaches the preset value, the water pump stops, thus achieving automatic preservative solution preparation, saving manpower and resources, and improving the efficiency of preservative solution preparation.
