Description

Technical Field

[0001] This utility model relates to mixing equipment, and more particularly to an automatic heating and mixing device for raw material pretreatment. Background Technology

[0002] In some production processes, it is necessary to mix various raw materials. Due to the characteristics of each raw material, the mixing and reaction process takes a lot of time, resulting in low overall production efficiency and inability to complete processing quickly. Conventional preheating devices for raw materials cannot effectively control the temperature and lack overheat protection, resulting in unstable preheating effect, which is also not conducive to production.

[0003] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create an automatic heating and stirring device for raw material pretreatment, which would have greater industrial application value. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide an automatic heating and stirring device for raw material pretreatment.

[0005] This utility model discloses an automatic heating and stirring device for raw material pretreatment, comprising an outer shell, a stirring chamber inside the outer shell, a heating layer between the stirring chamber and the outer shell, a heating pipe installed in the heating layer, a drive motor installed at the upper end of the outer shell, the drive motor being fixedly connected to a rotating shaft via a coupling, multiple sets of stirring blades being installed on the rotating shaft, and the heating pipe being electrically connected to an industrial computer for control inside the outer shell.

[0006] This automatic heating and stirring device for raw material pretreatment places the raw materials in a stirring chamber and heats them through pipes in the heating layer. The stirring blades are driven by a motor to stir the materials, improving heating efficiency and enabling rapid heating of the raw materials for convenient subsequent production and processing.

[0007] Furthermore, a cover plate is installed at the top of the outer casing via a hinge, and a window is located below the cover plate for observation and feeding.

[0008] The cover plate at the top of the outer shell is an openable and closable structure, which allows for material feeding and observation when opened.

[0009] Furthermore, there is a discharge pipe at the bottom of the mixing chamber, and a discharge valve is installed at the end of the discharge pipe.

[0010] The discharge pipe at the bottom of the feeding hopper is used to discharge the raw materials after stirring and heating, making it convenient to collect and transfer them to the downstream production equipment.

[0011] Furthermore, the space inside the heating layer is connected to the water inlet pipe, the other end of which is connected to a water source. A solenoid valve is installed on the water inlet pipe, and the solenoid valve is electrically connected to the industrial computer.

[0012] The heating layer has a hollow structure. Water is introduced into the heating layer through the water inlet pipe. The total amount of water entering is controlled by a solenoid valve. By heating the water, the temperature inside the mixing chamber is kept relatively constant, avoiding local overheating that could damage the raw materials.

[0013] Furthermore, a connecting pipe is installed on the side wall of the heating layer, and two level gauges are installed on the connecting pipe with a spacing of 10-15cm between them. The level gauges are electrically connected to the industrial computer.

[0014] The water level in the heating layer is connected to the connecting pipe, and the liquid level height can be obtained on the connecting pipe. Two liquid level gauges are used to detect the relative height of the liquid level. When the liquid level is too high or too low, an alarm message is triggered.

[0015] Furthermore, the level gauge and the connecting pipe are fixedly installed using clamps.

[0016] The level gauge is fixed by clamps, and its relative height can be adjusted.

[0017] Furthermore, the bottom of the mixing chamber has a conical structure that is lower on the inside and higher on the outside.

[0018] The conical structure at the bottom of the mixing chamber facilitates the flow of materials to the bottom and makes discharge easier.

[0019] By means of the above solution, the present invention has at least the following advantages: This automatic heating and stirring device for raw material pretreatment places the raw material in the stirring chamber and improves the heating efficiency of the raw material through the dual operation of heating and stirring, greatly reducing the subsequent processing time. At the same time, the liquid level gauge can monitor the water used for heating to avoid overheating caused by insufficient heating water.

In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this invention are described in detail below with reference to the accompanying drawings.

[0026] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0027] See Figure 1 This type of automatic heating and stirring device for raw material pretreatment has a stirring chamber 2 inside the outer shell 1 for placing raw materials. A heating layer 3 is located around the outer ring of the stirring chamber 2. The heating layer 3 is hollow and can be filled with water, which covers the heating pipes 4. The pipes 4 heat up after being powered on, raising the water temperature. The heating temperature is controlled by an industrial computer within the device to meet the heating needs of different raw materials. Water-insulated heating ensures more uniform heating and prevents excessively high temperatures at the heat source. Simultaneously, the drive motor 5 rotates the stirring blades 7 on the rotating shaft 6, stirring and heating at the same time, resulting in higher heating efficiency. The heated raw materials can then be processed more quickly in subsequent stages, improving the heating efficiency of the final stages.

[0028] See Figure 2 The cover plate 8 at the top of the outer shell 1 can be flipped open by the action of the hinge. After opening, the raw materials can be added into the mixing chamber 3, and the processing situation can be observed during the processing.

[0029] A discharge pipe 9 is installed at the bottom of the mixing chamber 2. By opening the discharge valve, the raw materials can be discharged from the discharge pipe 9 for easy access.

[0030] To facilitate water filling of the heating layer 3, the water inlet pipe 10 is directly connected to the water source / faucet. The solenoid valve 11 installed on the water inlet pipe 10 can be opened and closed under the control of the industrial computer, which facilitates water filling.

[0031] The connecting pipe 12 is connected to the heating layer 3. Water in the heating layer 3 flows into the connecting pipe 12. The water level in the heating layer 3 can be displayed on the connecting pipe 12. Two sets of liquid level gauges 13 are installed on the connecting pipe 12 to monitor the liquid level in the connecting pipe 12.

[0032] The two level gauges 13 are ultrasonic level gauges, which can detect the liquid level. The distance between the two level gauges 13 is between 10-15cm to meet the needs of liquid level adjustment.

[0033] See Figure 1 and Figure 3 The level gauge 13 is fixed by clamps, which allows for adjustment of the installation height of the level gauge 13 to meet the needs of different applications.

[0034] The conical structure at the bottom of the mixing chamber 3 facilitates the flow of raw materials to the bottom and makes material discharge easier.

[0035] The working principle of this utility model is as follows:

[0036] When using this automatic heating and stirring device for raw material pretreatment, the heating temperature is first set on the industrial computer. Then, water is injected into the heating layer 3 through the water inlet pipe 10 and the outlet pipe 4 heats the water, raising the temperature of the entire stirring chamber 2. A temperature sensor is installed in the heating layer 3 to monitor the temperature of the water used for heating. Heating stops when the temperature reaches the preset temperature and restarts when the temperature is too low. Then, the raw material is injected into the stirring chamber 2, and the drive motor 5 is started to perform synchronous stirring and heating, improving the heating efficiency.

[0037] When the water level in the heating layer 3 exceeds the upper level gauge 13, the control solenoid valve 11 closes to stop water injection. When the water level is lower than the lower level gauge 13, all heating / stirring equipment in this device shuts down for protection to prevent overheating and water temperature rise, which would affect the temperature inside the stirring chamber 3. At this time, the control solenoid valve 11 opens to add water, ensuring the water quantity and guaranteeing the stable operation of this device.

[0038] When the water level approaches the upper level gauge 13 and the temperature inside the heating layer 3 is also higher than the preset temperature, the device is forcibly shut down and restarted after being handled by the worker.

[0039] When the water level exceeds the upper level gauge 13, and the water temperature is detected by the temperature sensor and found to be lower than the preset value, heating operation can still be performed to raise the water temperature to the preset value. A slightly higher water level will not affect the operation of this device. As long as the water temperature is kept at the preset value, the raw materials can be heated.

[0040] The industrial computer inside this device is connected to a stirring timer, which controls the running time of the drive motor 5. It controls different stirring times for different quantities and qualities of raw materials, accurately controlling the raw material processing time and avoiding excessive stirring time that would affect production efficiency.

[0041] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships.

Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0043] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present utility model.
