Description

Technical Field

[0001] This utility model relates to the field of concrete water-reducing agent processing technology, and in particular to a concrete water-reducing agent heating device. Background Technology

[0002] Concrete water-reducing agent is a chemical admixture added during concrete mixing. It can significantly reduce the amount of mixing water while maintaining a relatively constant slump of the concrete. This helps improve the strength, durability, and impermeability of the concrete. The water-reducing agent is adsorbed onto the surface of cement particles, generating electrostatic repulsion or steric hindrance effects, which disperses the cement particles and releases the water surrounding them. There are various types, such as ordinary water-reducing agents and high-efficiency water-reducing agents. Different types are suitable for different construction requirements and concrete performance needs. It is an indispensable material in modern concrete construction. Heating devices are required during the processing of concrete water-reducing agents.

[0003] In the prior art, such as the utility model with publication number CN212142215U, this utility model relates to the field of water-reducing agent heating devices, specifically a concrete water-reducing agent heating device, including a device shell and a support frame fixed to the device shell. Inside the device shell, a first rotating tube and a second rotating tube, both of which are rotatable, are installed sequentially from left to right. A stirring tube is fixedly connected to the outer surface of both the first rotating tube and the second rotating tube. A spur gear is fixedly connected to the outer surface of both the first rotating tube and the second rotating tube extending to the top of the device shell. A servo motor is provided at the top of the device shell. A drive gear is fixedly connected to the output end of the servo motor. Both of the spur gears are meshed with the drive gear. A first connecting tube is provided at the top of the first rotating tube. A heater is fixedly connected to the end of the first connecting tube. This invention uses circulating heating of the medium oil flowing through two stirring devices, resulting in a high heating rate, uniform heating of the raw materials, and low heat loss. However, some heating devices with enclosed structures lack an effective pressure release mechanism. When the water-reducing agent generates gas during the heating process or the temperature becomes too high, it may lead to excessive internal pressure and pose a risk of explosion. For example, some water-reducing agents decompose at high temperatures to generate gas. If the gas cannot be discharged in time, the internal pressure of the device will rise sharply.

[0004] To address the issue that some enclosed heating devices lack effective pressure release mechanisms, which could lead to excessive internal pressure and explosion risks when the water-reducing agent generates gas or the temperature becomes too high during heating, current technology relies on operator supervision. However, this increases the difficulty of operating the equipment and further increases safety hazards. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing heating devices with enclosed structures that lack effective pressure release mechanisms. When the water-reducing agent generates gas or the temperature is too high during the heating process, it may cause excessive internal pressure and pose a risk of explosion. Therefore, this invention proposes a concrete water-reducing agent heating device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a concrete water-reducing agent heating device, comprising a base and a pressure relief device. A tank bottom is provided on the surface of the base, and an organic body is provided on the surface of the tank bottom. The pressure relief device is located on one side of the organic body and includes an air pipe fixedly connected to the organic body. A partition is fixedly connected to the inner wall of the air pipe, and air holes are provided on the surface of the partition. A crossbar is slidably connected to the surface of the partition. A cover is fixedly connected to one side of the crossbar, and a baffle is fixedly connected to the side of the crossbar away from the cover. By providing the pressure relief device, when the internal air pressure of the organic body is too high, the pressure relief device can promptly discharge excess gas. Sustained high air pressure can damage the internal structure of the equipment, such as causing deformation of the container wall or damage to internal precision components. The pressure relief device reduces the occurrence of such situations by promptly discharging high-pressure gas, thus extending the service life of the equipment.

[0007] Preferably, the cover is fitted onto the air pipe, and the surface of the baffle is provided with an arc-shaped hole. By providing the cover, when the internal air pressure of the machine is too high, the cover can open the air pipe through a series of mechanical transmissions under the action of air pressure, so that the gas can be discharged, which plays a key role in relieving pressure. This helps to maintain the stability of the internal air pressure of the machine and prevent safety accidents such as explosions caused by excessive air pressure, thus ensuring the safety of the equipment and operators.

[0008] Preferably, a pressure spring is fitted on the surface of the crossbar, and the two ends of the pressure spring are fixedly connected to the baffle and the partition, respectively. By setting the pressure spring, when the internal air pressure of the machine body decreases, the pressure spring loses its restraint and generates elastic force, which can push the baffle to drive the crossbar to slide and reset, so that the cover is re-fitted on the air pipe, thereby realizing the automatic reset of the pressure relief device.

[0009] Preferably, the lower surface of the machine body is provided with a combination device, which includes a sealing ring fixedly connected to the base. A connecting rod is fixedly connected to one side of the machine body, and an insertion rod is fixedly connected to one side of the tank bottom. A slot is provided on the lower surface of the machine body, and the insertion rod is inserted into the slot on the lower surface of the machine body. By providing the combination device, it is convenient to clean the bottom of the equipment tank. Due to the detachable structure, when dirt accumulates at the bottom of the tank and needs to be cleaned, the machine body can be easily removed to expose the bottom of the tank, thus solving the problem of difficult cleaning of the bottom of integrated heating equipment.

[0010] Preferably, a fixing rod is fixedly connected to one side of the tank bottom. The surface of the fixing rod has a hole. By setting the fixing rod, when it is necessary to clean the dirt on the bottom of the tank, the fixing rod can be disengaged from the relevant parts by rotating the knob, so that the machine body can be easily pulled up and removed to expose the bottom of the tank for thorough cleaning.

[0011] Preferably, the fixing rod and the connecting rod are inserted into the hole on the surface of the fixing rod, and the surface of the fixing rod is threaded with a knob. By setting the knob, when it is necessary to clean the dirt at the bottom of the tank, the machine body can be removed by simply turning the knob to disengage it from the connecting rod and then pulled upwards. The operation is relatively convenient. This design makes the disassembly process of the machine body not require complicated tools or operations, saving cleaning preparation time.

[0012] Preferably, there are two fixing rods, which are arranged in a mirror symmetrical manner. By setting the fixing rods, when the machine body is reset, the fixing rods are inserted into the connecting rods, and the machine body can be firmly fixed in the corresponding position by rotating the knob. This fixing method can prevent the machine body from being displaced due to vibration or other external forces during operation.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, by setting up a pressure relief device and a combined device, when the internal air pressure of the machine body is too high, the air pressure enters the air pipe and passes through the baffle and partition, then squeezes the cover. The crossbar of the cover slides under the force, opening the air pipe. At this time, the gas is discharged through the air holes on the surface of the partition. When the internal air pressure of the machine body decreases, the pressure on the cover decreases, the pressure spring loses its restraint and generates elastic force to push the baffle and drive the crossbar to slide back to its original position, and the cover is re-attached to the air pipe. However, after processing, dirt easily accumulates at the bottom of the tank. After the dirt solidifies, it easily forms a cocoon. Most heating equipment is integrated, making it difficult to completely clean the bottom of the tank during cleaning. At this point, turn the knob to disengage from the connecting rod, and pull upwards to remove the machine body, exposing the bottom of the tank for easy cleaning. After cleaning, reset the machine body, insert the insertion rod into the machine body, and simultaneously insert the fixing rod into the connecting rod. Turn the knob to fix the machine body. By designing this utility model, when the internal air pressure of the machine body is too high, the pressure relief device can promptly discharge excess gas. Sustained high air pressure can damage the internal structure of the equipment, such as causing deformation of the container wall and damage to internal precision components. The pressure relief device reduces the occurrence of such situations by promptly discharging high-pressure gas, thus extending the service life of the equipment. Attached Figure Description

[0021] Please see Figure 1-5 This utility model provides a technical solution: a concrete water-reducing agent heating device, including a base 1 and a pressure relief device 4. The surface of the base 1 is provided with a tank bottom 2, the surface of the tank bottom 2 is provided with an organic body 3, and the pressure relief device 4 is provided on one side of the organic body 3.

[0022] The following section will describe in detail the specific setup and function of its pressure relief device 4 and combined device 5.

[0023] In this embodiment: the pressure relief device 4 includes an air pipe 41, which is fixedly connected to the body 3. A partition 43 is fixedly connected to the inner wall of the air pipe 41. Air holes are opened on the surface of the partition 43. A crossbar 45 is slidably connected to the surface of the partition 43. A cover 44 is fixedly connected to one side of the crossbar 45, and a baffle 42 is fixedly connected to the side of the crossbar 45 away from the cover 44. By setting up the pressure relief device 4, when the internal air pressure of the body 3 is too high, the pressure relief device 4 can discharge the excess gas in time. Continuous high air pressure will damage the internal structure of the equipment, such as deforming the container wall and damaging the internal precision parts. The pressure relief device 4 reduces the occurrence of this situation by timely discharging high-pressure gas, thus extending the service life of the equipment.

[0024] Specifically, the cover 44 is fitted onto the air pipe 41, and the surface of the baffle 42 is provided with an arc-shaped hole. By setting the cover 44, when the internal air pressure of the machine body 3 is too high, the cover 44 can open the air pipe 41 through a series of mechanical transmissions under the action of air pressure, so that the gas can be discharged, which plays a key role in relieving pressure. This helps to maintain the stability of the internal air pressure of the machine body 3, prevent safety accidents caused by excessive air pressure, such as explosions, and ensure the safety of equipment and operators.

[0025] Specifically, a pressure spring 46 is fitted on the surface of the crossbar 45. The two ends of the pressure spring 46 are fixedly connected to the baffle 42 and the partition 43 respectively. By setting the pressure spring 46, when the air pressure inside the machine body 3 decreases, the pressure spring 46 loses its restraint and generates elastic force, which can push the baffle 42 to drive the crossbar 45 to slide back to its original position, so that the cover 44 is re-fitted onto the air pipe 41, thereby realizing the automatic reset of the pressure relief device 4.

[0026] Specifically, a combination device 5 is provided on the lower surface of the body 3. The combination device 5 includes a sealing ring 51, which is fixedly connected to the base 1. A connecting rod 52 is fixedly connected to one side of the body 3, and an insertion rod 53 is fixedly connected to one side of the tank bottom 2. A slot is provided on the lower surface of the body 3, and the insertion rod 53 is inserted into the slot on the lower surface of the body 3. By setting up the combination device 5, it is convenient to clean the tank bottom 2 of the equipment. Due to the adoption of a detachable structure, when the tank bottom 2 accumulates dirt and needs to be cleaned, the body 3 can be easily removed to expose the tank bottom 2, thus solving the problem that it is difficult to clean the tank bottom 2 of the integrated heating equipment.

[0027] Specifically, a fixing rod 54 is fixedly connected to one side of the tank bottom 2, and a hole is opened on the surface of the connecting rod 52.

[0028] In this embodiment: by setting a connecting rod 52, when it is necessary to clean the dirt on the bottom of the tank 2, the connecting rod 52 can be disengaged from the relevant parts by rotating the knob 55, so that the machine body 3 can be easily pulled up and removed, exposing the bottom of the tank 2, which is convenient for thorough cleaning of the bottom of the tank 2.

[0029] Specifically, the fixing rod 54 is inserted into the hole on the surface of the connecting rod 52, and the fixing rod 54 is threaded with a knob 55.

[0030] In this embodiment: by setting the knob 55, when it is necessary to clean the dirt at the bottom of the tank 2, the body 3 can be removed by simply turning the knob 55 to disengage it from the connecting rod 52 and then pulled upwards. The operation is relatively convenient. This design makes the disassembly process of the body 3 free from complicated tools or operations, saving cleaning preparation time.

[0031] Specifically, there are two fixing rods 54, which are arranged in a mirror-symmetrical manner.

[0032] In this embodiment: by setting a fixing rod 54, when the machine body 3 is reset, the fixing rod 54 is inserted into the connecting rod 52, and by rotating the knob 55, the machine body 3 can be firmly fixed in the corresponding position. This fixing method can prevent the machine body 3 from being displaced due to vibration or other external forces during operation.

[0033] Working principle: By setting up a pressure relief device 4 and a combination device 5, when the internal air pressure of the machine body 3 is too high, the air pressure enters the air pipe 41 and passes through the baffle 42 and partition 43, then squeezes the cover 44. The crossbar 45 of the cover 44 slides and opens the air pipe 41. At this time, the gas is discharged through the air holes on the surface of the partition 43. When the internal air pressure of the machine body 3 decreases, the pressure of the cover 44 decreases, the pressure spring 46 loses its restraint and generates elastic force to push the baffle 42 and drive the crossbar 45 to slide back to its original position. The cover 44 is then re-sleeved onto the air pipe 41. After processing, dirt easily accumulates at the bottom of the tank 2. After the dirt solidifies, it easily forms a cocoon. Most heating equipment is integrated, making it difficult to clean the bottom of the tank. 2. Perform a complete cleaning. At this time, turn knob 55 to disengage from connecting rod 52 and pull upward to remove body 3. The bottom 2 of the tank is exposed for easy cleaning. After cleaning, reset body 3, insert rod 53 into body 3, and at the same time insert fixing rod 54 into connecting rod 52. Turn knob 55 to fix body 3. By setting this utility model, when the internal air pressure of body 3 is too high, pressure relief device 4 can timely discharge excess gas. Continuous high air pressure will damage the internal structure of the equipment, such as deforming the container wall and damaging internal precision parts. Pressure relief device 4 reduces the occurrence of such situations by timely discharge of high-pressure gas, thus extending the service life of the equipment.
