Abstract
Description
Technical Field
[0001] This utility model relates to the field of lard processing technology, specifically to a lard storage tank. Background Technology
[0002] Lard, also known as pork fat, is divided into edible lard and industrial lard, depending on the type of oil. Edible lard can be used for stir-frying and making pastries, while industrial lard is an important raw material for soap making. Lard usually solidifies at room temperature. This is because the fat in lard crystallizes upon cooling. The solidification point of lard is generally between 28°C and 48°C, so at room temperature (usually 20°C to 25°C), lard is solid.
[0003] In the process of lard production, the refined lard needs to be stored in oil storage tanks for subsequent packaging. When lard is added to the oil storage tank, it is mostly in a liquid state and its temperature is high, causing the oil storage tank to expand due to heat. Moreover, after the lard cools and solidifies, it is inconvenient to drain the lard from the tank. Therefore, we propose a lard storage tank to solve the problems mentioned above. Utility Model Content
[0004] The purpose of this utility model is to provide a lard storage tank to solve the problems mentioned in the background art, where lard is mostly in a liquid state when added to the storage tank, and its temperature is relatively high, causing the storage tank to expand due to heat. Furthermore, after the lard cools and solidifies, it is inconvenient to drain the lard from the tank.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a lard storage tank, comprising:
[0006] The tank body has a support fixedly installed at the bottom and an oil drain pipe connected to the outer side of the bottom end of the tank body. A motor is installed at the bottom end of the tank body and a discharge shaft is connected to the output end of the motor. An observation window is provided on the outer side of the tank body and an oil inlet pipe is connected to the top of the tank body. A heating plate is connected to the outer side of the tank body and an insulation sleeve is provided on the outside of the tank body.
[0007] The pressure relief pipe is fixedly connected to the top of the tank body, and a pressure relief hole is opened on the outside of the pressure relief pipe. A piston is installed inside the pressure relief pipe, and a through hole is opened inside the piston. A spring is connected to the top of the piston.
[0008] Preferably, observation windows are symmetrically arranged on the upper and lower sides of the tank.
[0009] Preferably, the discharge shaft is a spiral feeding shaft, and the outside of the discharge shaft is in contact with the inner wall of the tank.
[0010] Preferably, the heating plate is positioned at an equal angle on the outside of the tank, and the insulation sleeve is wrapped around the outside of the heating plate.

[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: a lard storage tank, comprising: tank body 1, support 2, oil drain pipe 3, oil inlet pipe 4, motor 5, discharge shaft 6, heating plate 7, heat insulation sleeve 8, pressure relief pipe 9, pressure relief hole 10, piston 11, through hole 12, spring 13 and observation window 14;
[0023] Tank 1, with a bracket 2 fixedly installed at the bottom of the tank 1, and an oil drain pipe 3 connected to the outer side of the bottom end of the tank 1, a motor 5 installed at the bottom end of the tank 1, and a discharge shaft 6 connected to the output end of the motor 5, an observation window 14 provided on the outer side of the tank 1, an oil inlet pipe 4 connected to the top of the tank 1, a heating plate 7 connected to the outer side of the tank 1, and an insulation sleeve 8 provided on the outside of the tank 1.
[0024] The pressure relief pipe 9 is fixedly connected to the top of the tank body 1, and the pressure relief pipe 9 has a pressure relief hole 10 on its outside. The pressure relief pipe 9 has a piston 11 inside, and the piston 11 has a through hole 12 inside. The top of the piston 11 is connected to a spring 13.
[0025] like Figure 1 and Figure 2 The upper and lower sides of the tank 1 are symmetrically provided with observation windows 14 to facilitate observation of the oil level in the tank 1. The discharge shaft 6 is a spiral feeding shaft, and the outside of the discharge shaft 6 is in contact with the inner wall of the tank 1 to facilitate the discharge of lard in the tank 1. The heating plate 7 is set at an equal angle on the outside of the tank 1, and the heat insulation sleeve 8 is wrapped around the outside of the heating plate 7 to facilitate the heating and heat preservation of the tank 1.
[0026] like Figure 2 and Figure 3 The pressure relief pipe 9 has two sets of pressure relief holes 10 at the top and bottom, and each set of pressure relief holes 10 is set at an equal angle on the pressure relief pipe 9 to facilitate pressure relief in the tank 1. The piston 11 is slidably sealed to the pressure relief pipe 9, and the through hole 12 in the piston 11 has a "T" shaped cross section to facilitate air circulation.
[0027] Working principle: When using this lard storage tank, if... Figure 1 As shown, the refined lard is added to tank 1 through inlet pipe 4. The observation window 14 on tank 1 allows for easy monitoring of the amount of lard added. When lard is added to tank 1, the temperature inside tank 1 rises, as... Figure 3As shown, the air in the tank 1 compresses the piston 11, causing the piston 11 to compress the spring 13 and slide, thereby connecting the through hole 12 in the piston 11 with the pressure relief hole 10 above the pressure relief pipe 9, facilitating the depressurization in the tank 1. After the tank 1 is cooled down, the pressure in the tank 1 is less than the pressure of the spring 13, causing the piston 11 to move down, connecting the through hole 12 in the piston 11 with the pressure relief hole 10 below the pressure relief pipe 9, facilitating the entry of outside air into the tank 1 to balance the pressure in the tank 1.
[0028] When it is necessary to drain the lard from tank 1, such as Figure 2 As shown, by activating the heating plate 7, the heating plate 7 heats the tank 1, causing the lard on the side of the tank 1 to melt, and the lard inside the tank 1 can fall under the action of gravity. By activating the motor 5, the motor 5 drives the discharge shaft 6 to rotate, and the discharge shaft 6 squeezes the paste-like lard in the tank 1 and discharges it through the oil discharge pipe 3. This is the entire working process of the lard storage tank. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
