Description

Technical Field

[0001] This solution belongs to the technical field of regulating devices, specifically relating to a moisture regulating device for aggregates used in mortar production. Background Technology

[0002] Utility model patent CN222115525U discloses a sand and gravel aggregate humidification device, including a support leg with a humidification box fixedly mounted on it. An inlet is located at the upper part of one end of the humidification box, and a sand and gravel aggregate discharge hood is fixedly connected to the inlet. An outlet is located at the bottom of one end of the humidification box. A conveying component is installed inside the humidification box, contacting the sand and gravel aggregate and conveying the aggregate falling from the inlet to the outlet for discharge. A cover plate is installed on the top of the humidification box, and a humidification component is installed at the bottom of the cover plate, positioned above the conveying component. This utility model can effectively humidify sand and gravel aggregate, improving humidification efficiency. Furthermore, since the sand and gravel aggregate does not contact the humidification component, it reduces the later maintenance costs of the humidification component and extends the overall service life of the sand and gravel aggregate humidification device.

[0003] However, when humidifying aggregates, water is typically added directly to the device via a water pipe. The internal mixing mechanism then stirs the aggregates and water for an extended period to ensure uniform mixing. However, simply adding water arbitrarily leads to inefficient and uneven mixing. Furthermore, the humidity of the aggregates needs to be controlled according to the application scenario. Adjusting the humidity based on experience results in variations in humidity between batches, leading to differences in performance during subsequent use. Therefore, improvements to the existing technology are necessary. Utility Model Content

[0004] The purpose of this solution is to provide a moisture control device for aggregates used in mortar production. This addresses the problem of directly adding water to the device via pipes during humidification, followed by prolonged mixing of aggregates and water using an internal stirring mechanism to ensure uniformity. However, simply adding water arbitrarily leads to inefficient and uneven mixing. Furthermore, the moisture content of aggregates needs to be controlled according to the application scenario. Adjusting aggregate moisture based on experience results in variations in moisture content between batches, leading to differences in performance during subsequent use.

[0005] To achieve the above objectives, this solution provides a mortar production aggregate moisture regulation device, including a mixing tank. Four evenly distributed support legs are fixedly connected to the lower surface of the mixing tank. A cylindrical body is fixedly connected inside the mixing tank. An inlet is provided at the lower part of the cylindrical body, and an outlet is provided at the upper part of the cylindrical body. An end cap is threadedly connected to the outer side of the lower end of the cylindrical body. A tank cover is screwed to the upper end of the mixing tank. A feed hopper is fixedly connected inside the tank cover. A stirring mechanism is provided on the tank cover. A connecting pipe is fixedly connected inside the tank cover. A water inlet mechanism is provided on the tank cover.

[0006] The principle of this solution is as follows: During use, aggregate is fed into the mixing tank from the feed hopper. The operating time of the water pump is preset via an external controller based on the aggregate quantity. Simultaneously, the rotating ring is manually rotated, causing a spiral motion between the ring and the adjusting cylinder. This movement of the ring moves the sliding pin, which in turn moves the plug, changing the distance between the plug and the connecting pipe. This alters the cross-section of the water inlet at the upper end of the connecting pipe, thus varying the water inlet speed. By controlling the water pump's inlet time, the water volume and speed can be controlled, regulating the aggregate's moisture content. Furthermore, the variation in the water inlet speed ensures uniform mixing of the aggregate and water. The water pump's feed enters the rotating cylinder through the connecting pipe, which in turn feeds water into the perforated pipe, causing the perforated pipe to spray water outwards. The aggregate at the bottom of the mixing tank, under gravity, passes through the cylinder... The feed inlet enters the cylinder, the motor is started, the motor drives the drum to rotate, the drum drives the perforated tube to rotate, the perforated tube drives the conveyor blade to rotate, the conveyor blade rotates to convey the aggregate upwards, and thus the aggregate at the bottom of the cylinder is conveyed and discharged from the discharge port of the cylinder. The drum drives the support to rotate, the support drives the scraper to rotate, the scraper rotates to scrape the surface of the mixing tank and the cylinder, and can also stir and mix the aggregate. Water is introduced into the drum through the connecting pipe, and then the water can enter the perforated tube and be sprayed out. At the same time, the motor drives the drum to rotate, and thus the perforated tube rotates, so that the aggregate is evenly sprayed with water by the perforated tube. At the same time, the rotation of the perforated tube causes the conveyor blade to convey the aggregate in the cylinder, so that the aggregate at the bottom of the mixing tank is conveyed and discharged from the discharge port at the top of the cylinder for circulation, thus making the aggregate humidification more efficient and uniform, avoiding uneven mixing of aggregate and excessive local moisture differences.

[0007] The technical advantages of this solution are as follows: water is introduced into the rotating drum through a connecting pipe, allowing the water to enter the perforated pipe and be sprayed out. Simultaneously, the motor drives the rotating drum to rotate, which in turn causes the perforated pipe to rotate, ensuring that the aggregate is evenly sprayed with water through the perforated pipe. At the same time, the rotation of the perforated pipe allows the conveying knife to transport the aggregate inside the drum, so that the aggregate at the bottom of the mixing tank is transported and discharged from the discharge port at the top of the drum for circulation. This makes the humidification of the aggregate more efficient and uniform, avoiding uneven mixing of the aggregate and preventing excessive local humidity differences in the aggregate.

[0008] Water is pumped into the regulating cylinder by a water pump. The rotating ring and the regulating cylinder make a spiral motion, which causes the ring to move the plug via a sliding pin. This changes the distance between the plug and the connecting pipe, thus changing the water inlet speed of the connecting pipe. At the same time, by controlling the water pump's water inlet time, the water inlet volume and speed can be controlled, thereby adjusting the moisture content of the aggregate. Furthermore, by changing the water inlet speed, the uniformity of the mixing between the aggregate and water can be ensured.

[0009] Furthermore, the stirring mechanism includes a motor. The motor is fixedly installed in the middle of the upper end of the tank lid. The rotating shaft of the motor passes through the tank lid and is rotatably connected to the tank lid. A rotating drum is fixedly connected to the lower end of the rotating shaft of the motor. An annular groove is formed in the middle of the rotating drum. The annular groove is slidably connected to a connecting pipe. A hollow tube is fixedly connected to the lower end of the rotating drum. The hollow tube is rotatably connected to the drum body. A conveying blade is fixedly connected to the outer side of the hollow tube. The conveying blade is rotatably connected to the drum body. A bracket is fixedly connected to the surface of the rotating drum. A scraper is fixedly connected to the lower end of the vertical part of the bracket. Water is introduced into the rotating drum through a connecting pipe, allowing the water to enter the perforated tube and be sprayed out. Simultaneously, the motor drives the rotating drum to rotate, which in turn rotates the perforated tube, ensuring that the aggregate is evenly sprayed with water. The rotation of the perforated tube also allows the conveying knife to transport the aggregate inside the drum, so that the aggregate at the bottom of the mixing tank is transported and discharged from the discharge port at the top of the drum for circulation. This makes the humidification of the aggregate more efficient and uniform, avoiding uneven mixing of the aggregate and preventing excessive local moisture differences in the aggregate.

[0010] Furthermore, the interior of the rotating drum is provided with water-permeable holes, which are connected to the annular groove. By providing water-permeable holes, water in the annular groove can enter the inner cavity of the rotating drum.

[0011] Furthermore, a retaining ring is fixedly connected to the outer side of the connecting pipe, and the retaining ring is rotatably connected to the rotating drum. By setting the retaining ring, the annular groove on the rotating drum is sealed.

[0012] Furthermore, the scraper is slidably connected to the mixing tank and the cylinder. By using the scraper, the surfaces of the mixing tank and cylinder are scraped and cleaned to prevent adhesion.

[0013] Furthermore, the water inlet mechanism includes an adjusting cylinder. The adjusting cylinder is fixedly connected to the upper end of the tank cover. A plug is slidably connected inside the connecting pipe, and a sliding pin is fixedly connected to the surface of the plug. The sliding pin and the adjusting cylinder are slidably connected. A rotating ring is threadedly connected to the outer side of the adjusting cylinder, and the rotating ring is slidably connected to the sliding pin. A water pump is fixedly installed at the upper end of the adjusting cylinder, and the suction end of the water pump passes through the adjusting cylinder and is fixedly connected to it. Water is introduced into the adjusting cylinder by the water pump. Rotating the rotating ring and the adjusting cylinder causes a threaded movement, which in turn causes the rotating ring to move the plug via the sliding pin. This changes the distance between the plug and the connecting pipe, thus changing the water inlet speed of the connecting pipe. Simultaneously, by controlling the water pump's inlet time, the water inlet volume and speed can be controlled, adjusting the aggregate moisture content. Furthermore, the variation in the water inlet speed ensures the uniformity of the mixing between the aggregate and water.

[0014] Furthermore, a retaining sleeve is fixedly connected to the surface of the sliding pin, and the retaining sleeve is slidably connected to the adjusting cylinder. By setting the retaining sleeve, the groove on the adjusting cylinder is sealed to prevent leakage. Attached Figure Description

Detailed Implementation

[0017] The implementation examples are basically as follows Figure 1 , Figure 2 As shown, this embodiment provides a mortar production aggregate moisture regulating device, including a mixing tank 1. Four evenly distributed support legs 2 are fixedly connected to the lower surface of the mixing tank 1. A cylinder 3 is fixedly connected inside the mixing tank 1. A feed inlet is opened at the lower part of the cylinder 3, and a discharge outlet is opened at the upper part of the cylinder 3. An end cap 4 is threadedly connected to the outer side of the lower end of the cylinder 3. A tank cover 5 is screwed to the upper end of the mixing tank 1. A feed hopper 6 is fixedly connected inside the tank cover 5. A stirring mechanism 7 is provided on the tank cover 5. A connecting pipe 8 is fixedly connected inside the tank cover 5. A water inlet mechanism 9 is provided on the tank cover 5.

[0018] like Figures 1-4 As shown, the stirring mechanism 7 includes a motor 71. The motor 71 is fixedly installed at the upper middle part of the tank cover 5. The rotating shaft of the motor 71 passes through the tank cover 5 and is rotatably connected to the tank cover 5. The lower end of the rotating shaft of the motor 71 is fixedly connected to a rotating drum 72. An annular groove 73 is opened in the middle of the rotating drum 72. A water-permeable hole is opened inside the rotating drum 72, and the water-permeable hole communicates with the annular groove 73. By setting the water-permeable hole, water in the annular groove 73 can enter the inner cavity of the rotating drum 72. The annular groove 73 is slidably connected to the connecting pipe 8. A retaining ring 74 is fixedly connected to the outside of the connecting pipe 8. The retaining ring 74 is rotatably connected to the rotating drum 72. By setting the retaining ring 74, the annular groove 73 on the rotating drum 72 is closed. A hollow tube 75 is fixedly connected to the lower end of the rotating drum 72. The hollow tube 75 is rotatably connected to the drum body 3. A conveying knife 76 is fixedly connected to the outside of the hollow tube 75. The conveying knife 76 is rotatably connected to the drum body 3. A bracket 77 is fixedly connected to the surface of the rotating drum 72. A scraper 78 is fixedly connected to the lower vertical part of the bracket 77. The scraper 78 is slidably connected to the mixing tank 1 and the drum 3. By setting the scraper 78, the surfaces of the mixing tank 1 and the drum 3 are scraped and cleaned to prevent adhesion. Water is introduced into the rotating drum 72 through the connecting pipe 8, so that the water can enter the hollow pipe 75 and be sprayed out. At the same time, the motor 71 drives the rotating drum 72 to rotate, which in turn causes the hollow pipe 75 to rotate, so that the aggregate is evenly sprayed with water by the hollow pipe 75. At the same time, the rotation of the hollow pipe 75 causes the conveying knife 76 to convey the aggregate in the drum 3, so that the aggregate at the bottom of the mixing tank 1 is conveyed and discharged from the discharge port at the top of the drum 3 for circulation, thereby making the aggregate humidification more efficient and uniform, avoiding uneven mixing of aggregate and causing excessive local humidity difference in aggregate.

[0019] like Figure 1 , Figure 2 , Figure 5As shown, the water inlet mechanism 9 includes an adjusting cylinder 91. The adjusting cylinder 91 is fixedly connected to the upper end of the tank cover 5. A plug 92 is slidably connected inside the connecting pipe 8. A sliding pin 93 is fixedly connected to the surface of the plug 92. The sliding pin 93 and the adjusting cylinder 91 are slidably connected. A retaining sleeve 94 is fixedly connected to the surface of the sliding pin 93. The retaining sleeve 94 and the adjusting cylinder 91 are slidably connected. By setting the retaining sleeve 94, the groove on the adjusting cylinder 91 is sealed to prevent leakage. A rotating ring 95 is threadedly connected to the outside of the adjusting cylinder 91. The rotating ring 95 and the sliding pin 93 are slidably connected. A water pump 9 is fixedly installed at the upper end of the adjusting cylinder 91. 6. The suction end of the water pump 96 passes through and is fixedly connected to the regulating cylinder 91. Water is introduced into the regulating cylinder 91 through the water pump 96. By rotating the rotating ring 95 and the regulating cylinder 91, the rotating ring 95 can drive the plug 92 to move through the sliding pin 93. This changes the distance between the plug 92 and the connecting pipe 8, which in turn changes the water inlet speed of the connecting pipe 8. At the same time, by controlling the water inlet time of the water pump 96, the water inlet volume and water inlet speed can be controlled to adjust the moisture content of the aggregate. Furthermore, by changing the water inlet speed, the uniformity of the mixing of aggregate and water can be ensured.

[0020] The specific implementation process of this utility model is as follows: In use, aggregate is fed from the feed hopper 6 into the mixing tank 1. Then, based on the amount of aggregate, the working time of the water pump 96 is preset via an external controller. Simultaneously, the rotating ring 95 is manually rotated. The rotation of the rotating ring 95 and the adjusting cylinder 91 create a threaded motion, allowing the rotating ring 95 to move. The rotating ring 95 drives the sliding pin 93 to move, which in turn drives the plug 92 to move. This movement of the plug 92 changes the distance between the plug 92 and the connecting pipe 8, causing the connecting pipe 8 to... The change in the cross-section of the water inlet allows for a change in the water inlet velocity of the connecting pipe 8. Simultaneously, by controlling the water inlet time of the water pump 96, the water inlet volume and velocity can be controlled, thus regulating the aggregate moisture content. Furthermore, the change in water inlet velocity ensures the uniformity of the aggregate and water mixing. The water pump 96 enters the rotating drum 72 through the connecting pipe 8. The rotating drum 72 then feeds water into the perforated pipe 75, causing the perforated pipe 75 to spray water outwards. The aggregate at the bottom of the mixing tank 1, under the influence of gravity, can pass through the feed inlet inside the cylinder 3. Upon entering the cylinder 3, the motor 71 is started, driving the rotating drum 72 to rotate. The rotating drum 72 drives the perforated tube 75 to rotate, which in turn drives the conveying blade 76 to rotate. The conveying blade 76 conveys the aggregate upwards, causing the aggregate at the bottom of the cylinder 3 to be discharged from the outlet of the cylinder 3. The rotating drum 72 drives the support 77 to rotate, which in turn drives the scraper 78 to rotate. The scraper 78 scrapes against the surfaces of the mixing tank 1 and the cylinder 3, and can also stir and mix the aggregate. The aggregate is then fed into the rotating drum 72 through the connecting pipe 8. Water is introduced into the inner cavity, allowing it to enter the perforated tube 75 and spray out. Simultaneously, the motor 71 drives the rotating drum 72 to rotate, which in turn causes the perforated tube 75 to rotate, ensuring that the aggregate is evenly sprayed with water through the perforated tube 75. At the same time, the rotation of the perforated tube 75 allows the conveying knife 76 to convey the aggregate inside the cylinder 3, so that the aggregate at the bottom of the mixing tank 1 is conveyed and discharged from the discharge port at the top of the cylinder 3 for circulation. This makes the humidification of the aggregate more efficient and uniform, avoiding uneven mixing of the aggregate and causing excessive local humidity differences in the aggregate.

[0021] Water is introduced into the rotating drum 72 through the connecting pipe 8, allowing the water to enter the perforated pipe 75 and be sprayed out. At the same time, the motor 71 drives the rotating drum 72 to rotate, which in turn causes the perforated pipe 75 to rotate, so that the aggregate is evenly sprayed with water through the perforated pipe 75. Meanwhile, the rotation of the perforated pipe 75 allows the conveying knife 76 to convey the aggregate in the drum 3, so that the aggregate at the bottom of the mixing tank 1 is conveyed and discharged from the discharge port at the top of the drum 3 for circulation, thereby making the humidification of the aggregate more efficient and uniform, avoiding uneven mixing of the aggregate and causing excessive local humidity differences in the aggregate.

[0022] Water is pumped into the regulating cylinder 91 by the water pump 96, and the rotating ring 95 and the regulating cylinder 91 make a spiral motion, which causes the rotating ring 95 to drive the plug 92 to move through the sliding pin 93. This changes the distance between the plug 92 and the connecting pipe 8, which in turn changes the water inlet speed of the connecting pipe 8. At the same time, by controlling the water inlet time of the water pump 96, the water inlet volume and water inlet speed can be controlled to regulate the moisture content of the aggregate. Furthermore, by changing the water inlet speed, the uniformity of the mixing of aggregate and water can be ensured.
