Description
Technical Field
[0001] The utility model relates to the technical field of mixing, in particular to a material stirring temperature control device. Background Art
[0002] The mixed material is one of the crucial raw materials in production. It is composed of a variety of different materials. Through mixing, different components can be evenly dispersed during the production process, ensuring the quality stability and production efficiency of the product. If the mixing is uneven, it will lead to unstable product quality and even threaten the normal operation of the production line.
[0003] The temperature of the mixed material is one of the very important control variables in the mixing process because the melting point, boiling point, and fluidity of the components of the mixed material are all affected by temperature, and too high or too low temperature will affect the chemical and physical properties of the raw materials in the mixed material, ultimately affecting the quality and appearance of the product. If the temperature difference between components is too large, problems such as viscosity or uneven dispersion will occur. Therefore, the control of the temperature of the mixed material is very important. At present, in the field of stirring and mixing equipment, the precise control of the temperature of the mixed material remains a difficult problem. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide a material stirring temperature control device that can precisely control the temperature of the mixed material.
[0005] During the high-speed mixing process of the mixer, due to the high-speed collision and friction between the material itself, the material and the barrel wall of the mixing barrel, and the blades, the temperature of the material will rise rapidly. For some materials that are not tolerant to high temperatures, this is a fatal problem, and phenomena such as plasticization, agglomeration, and sticking to the barrel will occur. To solve the above problems, the technical solution adopted by the present invention is to set a hollow closed interlayer in the mixing barrel and add a refrigerant medium such as circulating water or cooling water to the hollow closed interlayer to cool the material in the mixing barrel. The material in the mixing barrel is cooled by indirect heat exchange with the refrigerant medium. Specifically, there are two implementation structures. Of course, during the actual use process, there may also be a situation where the temperature of the material in the mixing barrel is too low and needs to be heated.

The sewage valve is usually in a normally closed state and is only opened when the hollow closed interlayer needs to be cleaned.
[0012] The second implementation structure is as follows: A material stirring temperature control device described in this solution includes: a stirring barrel, and the barrel wall of the stirring barrel is a double-layer structure with a hollow closed interlayer; a spiral guide plate that spirally winds and climbs upward is arranged in the hollow closed interlayer, and the hollow closed interlayer is divided into a spiral channel that spirally winds and climbs upward by the spiral guide plate; a water inlet pipe and a water outlet pipe are arranged on the outer barrel wall of the stirring barrel, the water inlet pipe is on the outer barrel wall of the stirring barrel at the bottom end of the spiral channel and the water inlet pipe is communicated with the spiral channel, and the water outlet pipe is on the outer barrel wall of the stirring barrel at the top end of the spiral channel and the water outlet pipe is communicated with the spiral channel.

[0023] The technical solution of the present utility model will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments Embodiment 1
[0024] In this embodiment, a material mixing temperature control device is designed based on the mixing barrel 1 in the material mixing and blending equipment. The barrel wall of the mixing barrel 1 is designed as a double-layer structure with a hollow closed interlayer, that is, it is composed of two parts: an inner barrel body 11 and an outer shell body 12. As shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , a number of baffle plates 4 are sequentially arranged at intervals from top to bottom in the hollow closed interlayer. Each baffle plate 4 divides the hollow closed interlayer into several independent and closed separate enclosed spaces 42 from top to bottom in sequence. A flow guiding port 41 is opened on each baffle plate 4. Each flow guiding port 41 can communicate with the upper and lower two separate enclosed spaces 42 separated by the baffle plate 4 where the flow guiding port 41 is located, and the upper and lower positions of the flow guiding ports 41 on two adjacent baffle plates 4 are staggered. On the outer barrel wall of the mixing barrel 1, that is, on the outer shell body 12, a water inlet pipe 3 and a water outlet pipe 2 are provided. The water inlet pipe 3 is communicated with the separate enclosed space at the lowest layer in the mixing barrel 1, and the water outlet pipe 3 is communicated with the separate enclosed space at the uppermost layer in the mixing barrel 1
[0025] When cooling the materials in the stirring barrel 1, the refrigerant medium continuously enters the lowest-layer separate enclosed space through the water inlet pipe 3, then sequentially enters the corresponding separate enclosed spaces 42 layer by layer upward through each diversion port 41, and finally flows out of the stirring barrel 1 through the water outlet pipe 2 at the topmost separate enclosed space. During the process of the refrigerant medium flowing in each separate enclosed space, when it is necessary to cool the materials in the stirring barrel 1, the selected temperature of the refrigerant medium is lower than the temperature of the materials in the stirring barrel 1. As for the specific temperature, it is determined according to actual needs. The refrigerant medium entering the hollow enclosed interlayer absorbs the temperature of the materials in the stirring barrel 1 to achieve the purpose of quickly cooling the materials in the stirring barrel 1. When it is necessary to heat the materials in the stirring barrel 1, the selected temperature of the refrigerant medium is higher than the temperature of the materials in the stirring barrel 1. As for the specific temperature, it is determined according to actual needs. The refrigerant medium releases heat to the materials in the stirring barrel 1 to achieve the purpose of quickly heating the materials in the stirring barrel 1.
[0026] In order to accurately control the flow rate of the refrigerant medium entering the hollow enclosed interlayer, the flow rate of the refrigerant medium flowing out of the hollow enclosed interlayer, and to know the temperature of the refrigerant medium entering the hollow enclosed interlayer and the temperature of the refrigerant medium flowing out of the hollow enclosed interlayer, so as to be able to more accurately control the temperature of the materials in the stirring barrel 1, as Figure 1 and Figure 2 shown, in this embodiment, a first flow rate regulating control valve 31, a first flowmeter 32 and a first water temperature control display instrument 33 are installed on the water inlet pipe 3. Among them, the first flow rate regulating control valve 31 is used to regulate the flow rate of the refrigerant medium in the water inlet pipe 3, the first flowmeter 32 is used to monitor the flow rate of the refrigerant medium in the water inlet pipe 3 in real time, and the first water temperature control display instrument 33 is used to monitor the temperature of the refrigerant medium in the water inlet pipe 3 in real time. A second flow rate regulating control valve 21, a second flowmeter 22 and a second water temperature control display instrument 23 are installed on the water outlet pipe 2. Among them, the second flow rate regulating control valve 21 is used to regulate the flow rate of the refrigerant medium in the water outlet pipe 2, the second flowmeter 22 is used to monitor the flow rate of the refrigerant medium in the water outlet pipe 2 in real time, and the second water temperature control display instrument 23 is used to monitor the temperature of the refrigerant medium in the water outlet pipe 2 in real time. A thermocouple for measuring the temperature of the materials in the stirring barrel 1 is provided on the barrel wall of the stirring barrel 1.
[0027] In this embodiment, the heights of all the separate enclosed spaces 42 are the same, and the upper and lower positions of the diversion ports 41 on two adjacent flow guiding plates 4 are staggered by 180°. Such a setting can extend the water flow path and improve the cooling efficiency or heating efficiency.
[0028] In addition, to maximize the length of the water flow path and improve the cooling or heating efficiency, in this solution, the position of the diversion opening 41 on the diversion plate 4 at the lowest separate enclosed space is staggered by 180° vertically from the position of the water inlet pipe 3, and the position of the diversion opening 41 on the diversion plate 4 at the uppermost separate enclosed space is staggered by 180° vertically from the position of the water outlet pipe 2. In addition, to facilitate the connection layout of the external water circulation pipeline, in this embodiment, the water outlet pipe 2 is located directly above the water inlet pipe 3.
[0029] To facilitate the sewage discharge of the hollow enclosed interlayer, in this embodiment, a sewage discharge pipe 5 communicating with the hollow enclosed interlayer is provided on the bottom of the mixing barrel 1, and a sewage discharge valve is installed on the sewage discharge pipe 5. The sewage discharge valve is normally in a normally closed state and will only be opened when the hollow enclosed interlayer needs to be cleaned.
[0030] When the temperature of the material in the mixing barrel is too high or too low during the mixing process, a refrigerant medium matching the required temperature is used to cool or heat the material in the mixing barrel. Through the first flow rate regulating control valve 31, the first flow meter 32, the first water temperature control display instrument 33, the second flow rate regulating control valve 21, the second flow meter 22, and the second water temperature control display instrument 23, the purpose of accurately controlling the temperature of the material in the mixing barrel is achieved, and the quality of the mixed material is better guaranteed. Embodiment 2
[0031] In this embodiment, a material stirring temperature control device is also designed based on the mixing barrel 1 in the material stirring and mixing equipment. The barrel wall of the mixing barrel 1 is designed as a double-layer structure with a hollow enclosed interlayer, that is, it is composed of an inner barrel body 11 and an outer shell body 12. The difference from Embodiment 1 is the different ways of restricting the flow mode of the water flow in the hollow enclosed interlayer. As Figure 5 shown, a spiral diversion plate 6 spirally winding and climbing upward is arranged in the hollow enclosed interlayer. The hollow enclosed interlayer is divided into a spiral channel 61 spirally winding and climbing upward by the spiral diversion plate 6. On the outer barrel wall of the mixing barrel 1, that is, on the outer shell body 12, a water inlet pipe 3 and a water outlet pipe 2 are provided. The water inlet pipe 3 is located on the outer barrel wall of the mixing barrel 1 at the bottom end of the spiral channel 61 and the water inlet pipe 3 communicates with the spiral channel 61. The water outlet pipe 2 is located on the outer barrel wall of the mixing barrel 1 at the top end of the spiral channel 61 and the water outlet pipe 2 communicates with the spiral channel 61. The water flow path is extended through the spiral channel 61 to improve the cooling or heating efficiency.
[0032] In order to precisely control the flow rate of the refrigerant medium entering the hollow closed interlayer, the flow rate of the refrigerant medium flowing out of the hollow closed interlayer, and to understand the temperature of the refrigerant medium entering the hollow closed interlayer and the temperature of the refrigerant medium flowing out of the hollow closed interlayer, so as to be able to more precisely control the temperature of the material in the mixing barrel 1, in this solution, a first flow rate regulating control valve 31, a first flow meter 32, and a first water temperature control display instrument 33 are installed on the water inlet pipe 3; a second flow rate regulating control valve 21, a second flow meter 22, and a second water temperature control display instrument 23 are installed on the water outlet pipe 2.

[0033] In this embodiment, the heights of all parts of the spiral channel 61 are the same. In addition, for the convenience of the connection layout of the external water circulation pipeline, in this embodiment, the water outlet pipe 2 is located directly above the water inlet pipe 3.
[0034] For the convenience of sewage discharge from the hollow closed interlayer, in this embodiment, a sewage discharge pipe 5 communicating with the hollow closed interlayer is provided on the bottom of the mixing barrel 1, and a sewage discharge valve is installed on the sewage discharge pipe 5. The sewage discharge valve is usually in a normally closed state and will only be opened when it is necessary to clean the hollow closed interlayer.
[0035] All material mixing equipment has a control system. In order to achieve automatic regulation of the flow rate of the cooling medium, the signal lines of the inlet water temperature control display instrument 33, the outlet water temperature control display instrument 23, the first flow meter 32, the second flow meter 22, and the signal line of the thermocouple are all connected to the control system. The first flow rate regulating control valve 31 and the second flow rate regulating control valve 21 also select the category of automatic control valves, and the control lines of the first flow rate regulating control valve 31 and the second flow rate regulating control valve 21 are also connected to the control system. At this time, the program of the control system is written so that the control system can receive the signals fed back by the inlet water temperature control display instrument 33, the outlet water temperature control display instrument 23, the first flow meter 32, the second flow meter 22, and the thermocouple and make judgments, and control the respective opening degrees of the first flow rate regulating control valve 31 and the second flow rate regulating control valve 21. It should be noted that the control system for writing the program of the control system belongs to the conventional control in the control field. Here, this control system is applied to the material mixing temperature control device.
