Description

Technical Field

[0001] The invention relates to the field of grease recovery, and in particular to an industrial mixed grease balancing heating device for a storage tank. Background Art

[0002] China is a major culinary country, and daily cooking mainly uses edible oil. As a result, a large amount of waste oil is discharged into the groundwater, forming a mixed industrial mixed oil. Industrial mixed oil is a general term for oil and fat. Vegetable oil is generally liquid at room temperature and pressure, called oil, while animal fat is solid at room temperature and pressure, called fat.

[0003] Discharging industrial mixed oils directly into rivers or municipal sewage pipes can cause severe environmental pollution. Oils and fats are also prone to condensing on the inside of municipal pipes, reducing water flow and even blocking them. Compared to other wastewater, the treatment of industrial mixed oil wastewater is more expensive and challenging. To promote clean energy and low-carbon development, biodiesel derived from industrial mixed oils and fats has begun to be used as a primary fuel, facilitating their storage, transportation, logistics, and refining. Industrial mixed oils and fats can be converted into biodiesel (fatty acid methyl or ethyl esters) through esterification and transesterification reactions. The resulting biodiesel has properties very similar to petroleum diesel, but is more environmentally friendly and affordable. Biodiesel used as a vehicle fuel can reduce exhaust emissions (CO2) by 80% and sulfur oxides by 100%.

[0004] Industrial mixed greases are mixtures that generally need to be heated to around 40°C to maintain good fluidity and meet normal storage and transportation requirements. Large tanks, especially those containing large quantities of industrial mixed grease, require extended heating times, resulting in reduced production efficiency and energy waste.

[0005] Existing grease heating equipment, such as the heating device for a grease heating room provided by Patent No. CN201520384289.1, uses a steam heating coil to heat the grease. However, if the coil is placed outside the tank, the outer side of the coil will lose more heat, affecting the heat utilization rate. If it is placed inside the tank, there is no other area in contact with the grease except the coil, and the heating efficiency is also worrying. At the same time, similar products do not have the function of real-time monitoring of the grease temperature and the heating medium temperature. Summary of the Invention

[0006] In response to the above-mentioned problems existing in existing grease heating devices, the present invention proposes an industrial mixed grease balanced heating device for storage tanks, the structure of which includes: a steam inlet pipe, a gas cylinder, a plurality of heating pipelines, and a drain pipeline connected in sequence; each heating pipeline includes a heating single pipe and a pipe joint assembly arranged between adjacent pipes, the pipe joint assembly includes a valve body, both ends of the valve body are connected to the heating single pipe, and a transfer pipe is provided on the upper part.

Both ends of the valve body 12 are connected to the heating single tube 3. The upper part is provided with a transfer tube 6. The transfer tube 6 is connected to the small-diameter end of the bell tube 8 through a compensation tube 7. The large-diameter end of the bell tube 8 is closed and outlet pipes 10 are provided on both sides of the end. The compensation tube 7 is convenient for adjusting the angle of the bell tube 8. The outlet pipe 10 is used to discharge condensed water; the outlet pipe 10 of the adjacent pipe segment assembly 4 is connected to the drain pipe 11, and the drain pipe 11 merges into the drain pipe 5; a number of U-shaped pipe clamps are provided on the drain pipe 5, and a number of pillars 21 are fixed to the U-shaped pipe clamps to set up the drain pipe 5.

[0026] More specifically, the heating pipeline is converged through the gas cylinder 2 and then flows into the drain pipeline 5.

[0027] More specifically, the steam inlet pipe 1, the air distribution cylinder 2, and the heating pipeline are in the same plane, and the angle between the plane and the horizontal plane is 5°-30°. The inclined setting facilitates the discharge of condensed water.

[0028] More specifically, the pipe joint assembly 4 includes a cubic valve body 12, the left, right and upper parts of the valve body 12 are all circular through-holes and the left and right ends and the upper part are provided with convex rings 13 for fixing with the heating single tube 3 or the adapter tube 6, the convexities are concentric with the through-holes and have the same inner diameter; the middle part of the inner side of the valve body 12 is opposite to the upper convex ring 13, and there is a circular groove 15 with a diameter equal to the inner diameter of the upper convex ring 13; the adapter tube 6 includes a hollow cylinder 20 at the upper part and a solid column 19 at the bottom, the inner side of the cylinder 20 is divided into two parts by a partition 18, the lower end of the partition 18 extends to the upper surface of the column 19, and the distance between the lower end of the cylinder 20 and the upper surface of the column 19 is equal to the inner diameter of the left or right end convex ring 13; a wireless sensor device 14 is embedded in one side of the valve body 12, and the wireless sensor device 14 includes a shell 22, a shell 2 2 is respectively equipped with a temperature sensor 24. The housing 22 is provided with an information processing module, a signal sending module, and a thermoelectric battery integrated on a circuit board. After the information processing module processes the information monitored by the temperature sensor 24, the signal sending module sends the temperature information of the inside and outside of the valve body 12 to the outside. The cold end of the thermoelectric battery is provided on the side of the housing 22 facing the outside of the valve body 12, and the hot end is provided on the side of the housing 22 facing the inside of the valve body 12. The cold end and the hot end are metal sheets 23 of different materials. The thermoelectric battery is a prior art. In the present invention, since the valve body 12 is provided inside the tank body, if an electrical detection device is required, it usually needs to be manually charged at intervals.

When the bottom of the column 19 of the adapter tube 6 is inserted into and abuts against the circular groove 15 of the valve body 12, the partition 18 completely blocks the passages on the left and right sides of the valve body 12, so that the steam must flow through the bell tube 8 before flowing to the next pipe section assembly 4; the connection between the heating single tube 3 and the bead 13 can be directly connected by thread or by using a direct pipe.

[0030] More specifically, a rubber layer for sealing is provided at the bottom of the column 19 .

[0033] The advantages of the present invention are:

[0034] 1. Add multiple pipe joint assemblies to the steam delivery pipeline. The trumpet tubes on the pipe joint assemblies increase the heating area and heat the tank bottom or tank wall at the same time, making the grease heated faster and more evenly;

[0035] 2. The valve body is equipped with a wireless sensor device, which contains a temperature difference battery to power the temperature sensor, signal processing module, and signal transmission module, without the need for manual charging;

[0036] 3. The design of the trumpet tube, permanent magnet and compensation tube makes it easy to adjust the angle and install. Therefore, the present invention can also be used for external heating of multiple tanks, that is, the trumpet tube is attached to the outer bottom of a small tank for heating.

[0037] The present invention adds a pipe joint assembly to the steam heating pipeline that can expand the heating area and monitor the temperature in real time. The pipe joint assembly can guide the steam into the trumpet tube attached to the bottom or side wall of the tank body, thereby expanding the heating area. At the same time, the wireless sensor device of the pipe joint assembly can monitor the steam temperature and grease temperature, and the temperature difference between the inside and outside of the valve body is sensed by the temperature difference battery to provide the necessary electrical energy for the wireless sensor device, without the need for additional charging operations.
