Abstract
Description
Technical Field
[0001] This utility model relates to the field of inorganic chemical technology, specifically to a device for controlling the specific gravity of viscous materials. Background Technology
[0002] Calcium ammonium nitrate is an important inorganic chemical product, primarily used in agriculture. In its production process, after batching, filtration, preheating, and evaporation, the concentrated evaporation liquid flows into a buffer tank via a control valve. After thorough mixing in the buffer tank, it enters the granulation process. If the specific gravity control of the evaporation liquid becomes abnormal during its flow into the buffer tank, it can easily lead to difficulties in forming the final product, affecting the continuous operation of production.
[0003] Currently, in the production methods of calcium ammonium nitrate in the industry, the specific gravity of the concentrated liquid after evaporation is mainly determined manually, supplemented by automatic control to adjust the production process. However, due to the viscous nature of the material, equipment maintenance becomes both frequent and difficult. Therefore, most manufacturers rely mainly on manual measurement for production. Production workers have to perform specific gravity measurement every 5 minutes. This not only increases the workload of production workers, but also makes the method of manual specific gravity measurement susceptible to human factors, resulting in errors in the measurement results, which in turn affects product quality and production efficiency. Utility Model Content
[0004] In view of this, the present invention provides a specific gravity control device for viscous materials to solve the problems that manual measurement increases the workload of production workers, and that manual measurement of specific gravity is easily affected by human factors, resulting in errors in the measurement results, which in turn affects product quality and production efficiency.
[0005] This utility model provides a device for controlling the specific gravity of viscous materials, including:
[0006] A material conveying pipe, one end of which is connected to an evaporator and the other end of which is connected to a buffer tank, and the inlet end of which has a first flow control element;
[0007] A bypass observation tube is provided on one side of the material conveying pipe and is connected to the material conveying pipe. The bypass observation tube is a transparent pipe and has a specific gravity detection structure inside. One end of the bypass observation tube is connected to the buffer tank.
[0008] Beneficial effects:
[0009] The design of the bypass observation tube enables real-time monitoring and control of the specific gravity of viscous materials, avoiding the tediousness and errors of manual measurement and improving production efficiency and product quality. Furthermore, the transparent nature of the bypass observation tube allows staff to directly observe the material's flow and specific gravity, facilitating timely detection and adjustment of problems in the production process. In addition, the inclusion of a specific gravity detection structure and a primary flow control component enables precise control of the material's specific gravity, ensuring the quality of the final product and the continuity of the production process.
[0010] In one optional embodiment, the bypass observation pipe is connected to the material conveying pipe via a diversion pipe, and the height of the end of the diversion pipe connected to the material conveying pipe is greater than the height of the end of the diversion pipe connected to the bypass observation pipe.
[0011] Beneficial effects:
[0012] By making the height of the end of the diversion pipe connected to the material conveying pipe greater than the height of the end of the diversion pipe connected to the bypass observation pipe, this design facilitates the smooth flow of material into the bypass observation pipe, preventing material from accumulating or clogging in the diversion pipe. At the same time, since the material has a certain gravitational potential energy during the flow process, this height difference design can give the material a certain impact force when entering the bypass observation pipe, which helps the material to be evenly distributed in the bypass observation pipe, thereby improving the accuracy of specific gravity detection.
[0013] In one alternative embodiment, the angle between the diversion pipe and the material conveying pipe is 45°.
[0014] Beneficial effects:
[0015] The 45° design ensures that the material can flow smoothly into the bypass observation pipe, while avoiding excessive material impact caused by an excessively large angle, which could damage the specific gravity detection structure or increase the error. At the same time, the 45° angle also makes the connection between the diversion pipe and the material conveying pipe more stable, improving the stability and reliability of the entire device.
[0016] In one alternative implementation, the diameter of the diversion pipe is smaller than that of the material conveying pipe and the bypass observation pipe.
[0017] Beneficial effects:
[0018] The diameter of the diversion pipe is smaller than that of the material conveying pipe and the bypass observation pipe. This design limits the amount of material entering the bypass observation pipe. Simultaneously, the smaller diameter of the diversion pipe also reduces the flow velocity of the material within it, resulting in a smoother flow into the bypass observation pipe and further improving the accuracy of specific gravity detection. Furthermore, the smaller diameter of the diversion pipe also reduces the overall size of the device, making it more compact and easier to install and maintain.
[0019] In one optional embodiment, the outer wall of the bypass observation tube is provided with a heat insulation structure.
[0020] Beneficial effects:
[0021] The insulation structure can maintain a stable temperature of the material inside the bypass observation tube, preventing the material from being affected by temperature changes in the accuracy of specific gravity detection. This insulation is especially important in the specific gravity detection of some temperature-sensitive materials.
[0022] In one alternative embodiment, the insulation structure includes a heating wire wound around the outer wall of the bypass observation tube, and the heating wire is connected to a power source.
[0023] Beneficial effects:
[0024] The design of the heating wire allows the insulation structure to adjust the temperature as needed, further improving the flexibility and accuracy of specific gravity detection.
[0025] In one optional implementation, the first flow control element and the specific gravity detection structure are respectively connected to the control system signal.
[0026] Beneficial effects:
[0027] The control system can adjust the opening of the first flow control component in real time according to the material specific gravity detected by the specific gravity detection structure, thereby achieving precise control of the material flow rate.
[0028] In one alternative embodiment, the other end of the bypass observation tube is in communication with the outside air, and the end of the bypass observation tube that is in communication with the buffer tank has a second flow control element.
[0029] Beneficial effects:
[0030] The second flow control device can be used to control the flow rate of material in the bypass observation tube. The operator can manually control the second flow control device according to the liquid level of the material in the bypass observation tube. When the liquid level of the material in the bypass observation tube is too high, the second flow control device is controlled to increase the amount of material entering the buffer tank in the bypass observation tube, so as to reduce the liquid level of the material entering the bypass observation tube and avoid the problem of overflow caused by excessive material in the bypass observation tube. When the liquid level of the material in the bypass observation tube is too low, the second flow control device is controlled to reduce the amount of material entering the buffer tank in the bypass observation tube.
[0031] In one alternative embodiment, the bypass observation tube contains a level gauge, and the level gauge and the second flow control element are respectively connected to the control system signal.
[0032] Beneficial effects:
[0033] The level gauge is used to detect the liquid level in the bypass observation tube. By installing the level gauge, operators can monitor the liquid level in the bypass observation tube in real time and control the second flow control device based on the liquid level information displayed by the level gauge to prevent overflow due to excessive material in the bypass observation tube. Simultaneously, the level gauge can also be connected to the control system signal. When the liquid level is higher or lower than the set value, the control system can automatically adjust the opening of the second flow control device to maintain a stable liquid level in the bypass observation tube.
[0034] In one alternative implementation, the first flow control element and the second flow control element are flow control valves. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0040] The following is combined Figure 1 The following describes embodiments of the present invention.
[0041] According to an embodiment of the present invention, a viscous material specific gravity control device is provided, comprising: a material conveying pipe 1 and a bypass observation pipe 4.
[0042] Specifically, one end of the material conveying pipe 1 is connected to the evaporator, and the other end of the material conveying pipe 1 is connected to the buffer tank 2. The inlet end of the material conveying pipe 1 has a first flow control element 3. A bypass observation pipe 4 is set on one side of the material conveying pipe 1 and is connected to the material conveying pipe 1. The bypass observation pipe 4 is a transparent pipe and has a specific gravity detection structure inside. One end of the bypass observation pipe 4 is connected to the buffer tank 2.
[0043] In this embodiment, the upper end of the material conveying pipe 1 is connected to the evaporator (not shown). The material in the evaporator can enter the buffer tank 2 through the material conveying pipe 1. The bypass observation pipe 4 is located on one side of the material conveying pipe 1 and is connected to the material conveying pipe 1. During the process of the material entering the buffer tank 2 through the material conveying pipe 1, a portion of the material will enter the bypass observation pipe 4. The bypass observation pipe 4 has a specific gravity detection structure (not shown). The specific gravity detection structure can detect the specific gravity of the material entering the bypass observation pipe 4. The operator can control the first flow control component 3 according to the detection result of the specific gravity detection structure. When the specific gravity is less than the set lower limit value, the first flow control component 3 is controlled to reduce the amount of material entering the material conveying pipe 1, so as to prolong the evaporation time of the material in the evaporator and increase the specific gravity of the material. When the specific gravity is greater than the set upper limit value, the first flow control component 3 is controlled to increase the amount of material entering the material conveying pipe 1, so as to shorten the evaporation time of the material in the evaporator and reduce the specific gravity of the material. The material that has completed the detection in the bypass observation pipe 4 will enter the buffer tank 2 along the bypass observation pipe 4.
[0044] Preferably, the specific gravity detection structure is a hydrometer.
[0045] In this utility model's viscous material specific gravity control device, the design of the bypass observation tube 4 enables real-time monitoring and control of the specific gravity of viscous materials, avoiding the tediousness and errors of manual measurement and improving production efficiency and product quality. Furthermore, the bypass observation tube 4 is a transparent pipe, allowing operators to directly observe the material's flow state and specific gravity, facilitating timely detection and adjustment of problems in the production process. In addition, by setting up a specific gravity detection structure and a first flow control component 3, precise control of the material's specific gravity is achieved, ensuring the quality of the final product and the continuous operation of the production process.
[0046] In one embodiment, the bypass observation pipe 4 is connected to the material conveying pipe 1 through the diversion pipe 5, and the height of the end of the diversion pipe 5 connected to the material conveying pipe 1 is greater than the height of the end of the diversion pipe 5 connected to the bypass observation pipe 4.
[0047] In this embodiment, as Figure 1As shown, the material in the material conveying pipe 1 can enter the bypass observation pipe 4 through the diversion pipe 5. The diversion pipe 5 is set at an angle, and the height of the end of the diversion pipe 5 connected to the material conveying pipe 1 is greater than the height of the end of the diversion pipe 5 connected to the bypass observation pipe 4. This design facilitates the smooth flow of material into the bypass observation pipe 4 and avoids the accumulation or blockage of material in the diversion pipe 5. At the same time, since the material has a certain gravitational potential energy during the flow process, this height difference design can make the material have a certain impact force when entering the bypass observation pipe 4, which helps the material to be evenly distributed in the bypass observation pipe 4, thereby improving the accuracy of specific gravity detection.
[0048] In this embodiment, the angle between the diversion pipe 5 and the material conveying pipe 1 is 45°. This angle design ensures that the material can flow smoothly into the bypass observation pipe 4, while avoiding excessive material impact due to an excessively large angle, which could damage the specific gravity detection structure or increase the error. At the same time, the 45° angle also makes the connection between the diversion pipe 5 and the material conveying pipe 1 more stable, improving the stability and reliability of the entire device.
[0049] In other alternative embodiments, the angle between the diversion pipe 5 and the material conveying pipe 1 can be 30° or 60°, etc., and the angle between the diversion pipe 5 and the material conveying pipe 1 can be an acute angle.
[0050] In this embodiment, the diameter of the diversion pipe 5 is smaller than that of the material conveying pipe 1 and the bypass observation pipe 4. This smaller diameter limits the amount of material entering the bypass observation pipe 4. Simultaneously, the smaller diameter of the diversion pipe 5 also reduces the flow velocity of the material within it, resulting in a smoother flow into the bypass observation pipe 4 and further improving the accuracy of the specific gravity detection. Furthermore, the smaller diameter of the diversion pipe 5 also reduces the overall size of the device, making it more compact and easier to install and maintain.
[0051] In one embodiment, the outer wall of the bypass observation tube 4 is provided with a heat insulation structure. The heat insulation structure can maintain the temperature stability of the material inside the bypass observation tube 4, and avoid the material from affecting the accuracy of specific gravity detection due to temperature changes. This is especially important in the specific gravity detection of some temperature-sensitive materials.
[0052] Specifically, the insulation structure includes a heating wire 6, which is wound around the outer wall of the bypass observation tube 4 and connected to a power source.
[0053] In one embodiment, the first flow control element 3 and the specific gravity detection structure are respectively connected to the control system signal. The control system (not shown) can adjust the opening of the first flow control element 3 in real time according to the specific gravity of the material detected by the specific gravity detection structure, thereby achieving precise control of the material flow rate. When the specific gravity detection structure detects that the specific gravity of the material is lower than the set value, the control system will automatically increase the opening of the first flow control element 3 to increase the material flow rate, thereby prolonging the evaporation time of the material and increasing the specific gravity of the material; conversely, when the specific gravity detection structure detects that the specific gravity of the material is higher than the set value, the control system will automatically decrease the opening of the first flow control element 3 to decrease the material flow rate, thereby shortening the evaporation time of the material and reducing the specific gravity of the material. Such automated control not only improves production efficiency but also greatly reduces the tediousness and error of manual operation.
[0054] Preferably, the control system is a PLC controller, in which a set specific gravity value can be input. The specific gravity detection structure transmits real-time detection data to the PLC controller, and the PLC controller controls the opening degree of the first flow control component 3 based on the real-time detection data.
[0055] In one embodiment, the other end of the bypass observation pipe 4 is connected to the outside air, and the end of the bypass observation pipe 4 connected to the buffer tank 2 has a second flow control element 8. The second flow control element 8 can be used to control the flow rate of the material in the bypass observation pipe 4. The operator can manually control the second flow control element 8 according to the liquid level of the material in the bypass observation pipe 4. When the liquid level of the material in the bypass observation pipe 4 is too high, the second flow control element 8 is controlled to increase the amount of material entering the buffer tank 2 in the bypass observation pipe 4, so as to reduce the liquid level of the material entering the bypass observation pipe 4 and avoid the problem of overflow caused by excessive material in the bypass observation pipe 4. When the liquid level of the material in the bypass observation pipe 4 is too low, the second flow control element 8 is controlled to reduce the amount of material entering the buffer tank 2 in the bypass observation pipe 4.
[0056] In one embodiment, the bypass observation tube 4 contains a level gauge 7, and the level gauge 7 and the second flow control element 8 are respectively connected to the control system signal.
[0057] Specifically, the level gauge 7 is used to detect the liquid level in the bypass observation tube 4. By installing the level gauge 7, operators can monitor the liquid level in the bypass observation tube 4 in real time and control the second flow control element 8 based on the liquid level information displayed by the level gauge 7 to prevent overflow due to excessive material in the bypass observation tube 4. Simultaneously, the level gauge 7 can also be connected to the control system signal. When the liquid level is higher or lower than the set value, the control system can automatically adjust the opening of the second flow control element 8 to maintain a stable liquid level in the bypass observation tube 4.
[0058] It should be noted that in order to realize the automatic control function of the second flow control component 8, the set liquid level value needs to be input into the control system first.
[0059] Preferably, the first flow control element 3 and the second flow control element 8 are flow control valves.
[0060] In this embodiment, the viscous material specific gravity control device also includes a control system. The control system receives detection signals from the specific gravity detection structure and the level gauge 7, and controls the opening degree of the first flow control element 3 and the second flow control element 8 according to the detection signals, thereby achieving precise control of the material flow rate and stable control of the material level in the bypass observation tube 4. The control system can be implemented using existing industrial automation control systems, the specific structure and working principle of which are well known to those skilled in the art and will not be described in detail here.
[0061] This utility model's viscous material specific gravity control device, through the design of the bypass observation tube 4, achieves real-time monitoring and control of the specific gravity of viscous materials, avoiding the tediousness and errors of manual measurement, and improving production efficiency and product quality. Simultaneously, by incorporating components such as a specific gravity detection structure, a first flow control element 3, a second flow control element 8, and a level gauge 7, it achieves precise control of material flow rate and stable control of the material level within the bypass observation tube 4, further enhancing the stability and reliability of the device.
[0062] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
