Abstract
Description
Technical Field
[0001] The utility model relates to the field of dairy product production, in particular to an energy-saving multi-stage heating device. Background Art
[0002] In the production process of dairy products, water of different temperatures is often required to participate in temperature regulation or certain chemical reactions. The existing water heating is mainly carried out by heating the water tank, which is generally electrically heated. This heating method often produces scale on the bottom and inner wall of the water tank, and the water tank needs to be cleaned frequently. The output hot water is generally output together with scale and impurities. This heating method is not suitable for dairy product production. Secondly, the existing heating water tank loses heat quickly and cannot maintain a constant temperature for a long time. Utility Model Content
[0003] The purpose of the utility model is to reduce heat loss and always keep the production water at a constant temperature through multi-stage heating. Once the temperature drops, the next stage heating tank is automatically replenished.
[0004] The utility model adopts the following technical solutions:
[0005] An energy-saving multi-stage heating device includes a support frame, which is divided into multiple layers, and each layer has fixed seats at the front and back ends. A heating tank body is placed between the seats on each layer. A water inlet pipe is provided at the bottom of each heating tank body, and a water outlet pipe is also provided at the top of each heating tank body. Filter plates are provided inside the water outlet pipes, and the water outlet pipes of adjacent heating tank bodies are connected to the water inlet pipes, and solenoid valves are provided at the connections. The heating tank body is also equipped with a heating component, and each heating component is connected to an external controller.
[0006] Preferably, an anti-collision plate is provided inside each heating tank body, and the anti-collision plate is close to the water inlet pipe, and the inner diameter of the end surface close to the water inlet pipe gradually increases from the inside to the outside.
[0007] Preferably, the heating assembly includes a chuck, a junction box, a waterproof joint and a U-shaped electric heating tube. The chuck is fixedly connected to the front end of the heating tank body. A junction box is provided at the front end of the chuck. A waterproof joint is provided at the front end of the junction box. The waterproof joint is connected to the internal circuit board of the junction box. Several U-shaped electric heating tubes are installed on the chuck. The U-shaped electric heating tubes extend into the heating tank body, and the end of each U-shaped electric heating tube is connected to the junction box.
[0008] Preferably, the number of the U-shaped electric heating tubes is not less than four, and one of them is distributed perpendicular to the other three.
[0009] Preferably, a plurality of circular holes are provided on the chuck, and the inner walls of the circular holes are in contact with the outer wall of the U-shaped electric heating tube.
[0010] Preferably, the U-shaped electric heating tubes are connected by a fixing plate.
[0011] Preferably, a temperature detector is fixedly mounted on each heating tank body, and the end of the temperature detector extends into the heating tank body.
[0012] Principle of this utility model:
[0013] First, the production water is pumped into the heating tank from the bottom water inlet pipe through an external water pump. At the same time, the heating component at the front end of the heating tank starts working. The first heating does not need to be heated to the specified temperature, which is equivalent to preheating. It can also be heated directly to the specified temperature. Then the solenoid valve is opened to input the water to the next layer of heating tank to continue heating or maintain the heating temperature. The solenoid valve mainly controls whether to input water to the next layer of heating tank. Specifically, whether to maintain a constant temperature or to heat step by step is based on actual needs. The baffle is to protect the U-shaped electric heating tube to prevent high-pressure water from directly contacting the U-shaped electric heating tube and causing damage to the U-shaped electric heating tube. Each layer is heated relative to the first level, so that it can be heated step by step or heated at a constant temperature at multiple levels at the same time, reducing heat loss.
[0014] The beneficial effects of the present invention are:
[0015] 1. The multi-layer heating tank body provided in the present invention can heat each heating tank body individually or as a whole through the heating component. Regardless of the heating method, the temperature of the final output water can be guaranteed to be constant.
[0016] 2. The utility model avoids the method of heating directly through the inner wall, reducing the production of scale. At the same time, when cleaning, it is only necessary to pull the heating component out of the heating tank body, which makes cleaning more convenient, and the filter plate in the outlet pipe can prevent impurities from entering the delivery pipeline.
