Description

Technical Field

[0001] This utility model relates to the field of heating device technology, and more specifically to a series-connected two-stage temperature control heating device. Background Technology

[0002] A temperature-controlled heating device is a device that can automatically adjust its heating power according to a preset temperature value to maintain the temperature of the heated object or environment within a target range. Its core function is to monitor the temperature in real time through a temperature sensor and, in conjunction with a controller, adjust the output power of the heating element to achieve precise temperature control.

[0003] In the existing technology CN201921069840.8, a single-stage flow-guiding, single-section heating structure is adopted. However, this single-stage heater has limitations in energy efficiency optimization. Furthermore, the centralized heating method of this structure results in uneven heat distribution and low temperature control accuracy. In contrast, using two separate heating structures connected in series, with each heating unit's temperature controlled independently to achieve two-stage heating, effectively solves the corresponding technical problems in CN201921069840.8.

[0004] Therefore, how to provide a series-connected two-stage temperature control heating device with two-stage stepped heating is one of the technical problems that urgently need to be solved in this field. Utility Model Content

[0005] In view of this, the present invention provides a series-connected two-stage temperature-controlled heating device. The purpose is to address the aforementioned shortcomings.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A series-connected two-stage temperature-controlled heating device includes: a primary heating component, a secondary heating component, and a connecting pipe;

[0008] The primary heating assembly includes: a primary input tube, a primary connector, a primary output tube, and two primary heating rods; the output end of the primary input tube is connected to the input end of the primary output tube through the primary connector; the two primary heating rods are respectively inserted into the primary input tube and the primary output tube;

[0009] The secondary heating assembly includes: a secondary input tube, a secondary connector, a secondary output tube, and two secondary heating rods; the output end of the secondary input tube is connected to the input end of the secondary output tube through the secondary connector; the two secondary heating rods are respectively inserted into the secondary input tube and the secondary output tube;

[0010] The output terminal of the first-stage output tube is connected to the input terminal of the second-stage input tube through the connecting tube.

[0014] The four slow-flow bends are respectively connected to the input end of the first-stage input pipe, the output end of the first-stage output pipe, the input end of the second-stage input pipe, and the output end of the second-stage output pipe;

[0015] Furthermore, the slow-flow bend connected to the output end of the first-stage output tube and the slow-flow bend connected to the input end of the second-stage input tube are connected through the connecting pipe.

[0016] The present invention achieves the following technical advantages over the prior art:

[0017] Two primary heating rods are respectively inserted into the primary input tube and the primary output tube for primary heating, and two secondary heating rods are respectively inserted into the secondary input tube and the secondary output tube for secondary heating. The output end of the primary output tube is connected to the input end of the secondary input tube through the connecting tube, which can achieve the technical effect of two-stage stepped heating in series.

[0018] The four slow-flow springs are respectively wound around the two primary heating rods and the two secondary heating rods. When the material flows, it moves along the slow-flow springs to make the raw material heat evenly.
