Description

Technical Field

[0001] This utility model relates to the technical field of concrete admixture addition equipment, and in particular to a quantitative filling device for concrete admixture production. Background Technology

[0002] Concrete admixtures are additives that are incorporated into the concrete mixing process. They account for less than 5% of the cement mass and are chemical substances that can significantly improve the performance of concrete. Concrete admixtures are characterized by a wide variety of types, small dosages, and significant performance enhancements. With technological advancements, admixtures have become a major component of concrete.

[0003] In concrete production or packaging plants, the use of integrated wet and dry premixed mortar equipment necessitates the addition of concrete admixtures during the mixing process, regardless of whether the mortar is dry or wet. The vibrations of external equipment during admixture addition and discharge cause dust to be blown up, reducing the amount of admixture that can be added and thus lowering concrete performance. Furthermore, this process pollutes the on-site construction environment and poses health hazards to construction workers. Utility Model Content

[0004] In view of this, the present invention aims to provide a quantitative filling device for the production of concrete admixtures, so as to ensure that the admixtures do not leak during the addition and transfer process, improve the performance of concrete, and protect the construction environment.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A quantitative filling device for producing concrete admixtures includes a base frame, an admixture buffer tank disposed on the base frame, and a screw conveyor, a quantitative conveying component, a vibration component, and a mixing tank connected in sequence from end to end.

[0007] The inlet of the screw conveyor is located at the outlet of the admixture buffer tank;

[0008] A weighing component is provided below the vibration component, and a support base is provided below the weighing component. The height of the support base and the base frame is adjustable.

[0009] The quantitative delivery assembly includes an upper connecting pipe, a lower output pipe, and a quantitative valve connected between the upper connecting pipe and the lower output pipe. The outlet end of the lower output pipe is provided with a pivotally connected plug plate.

[0010] After the additive is quantitatively delivered into the lower output pipe, the blocking plate is driven to open the outlet of the lower output pipe, and the weighing component weighs the additive that falls onto the vibration component.

[0011] Furthermore, the vibration assembly includes a vibrator and a transmission rail connected to the vibrating end of the vibrator, with the lower output tube positioned directly above the transmission rail.

[0012] Furthermore, the lower end of the vibrator is provided with a fixing plate, and the weighing assembly includes a plurality of weighing sensors evenly distributed on the fixing plate, and the fixing plate is provided with a plurality of mounting parts for fixing the weighing sensors;

[0013] One end of the weighing sensor is connected to the fixed plate, and the other end is fixed to the support base.

[0014] Furthermore, the lower output pipe includes an outer cylinder and an inner cylinder connected by an inner and outer sleeve. The plug plate is pivotally connected to the bottom end of the inner cylinder, the outer cylinder is fixedly connected below the metering valve, and the inner cylinder is correspondingly disposed at the outlet of the metering valve. The additive is transported through the inner cylinder.

[0015] Furthermore, a first driving part is provided on the outer side of the outer cylinder, and a connecting rod is connected to the power output end of the first driving part. The connecting rod is fixedly connected to the blocking plate.

[0016] The inner cylinder has a lifting lug on the outer side of its bottom end, and the blocking plate has a pin. The pin is inserted into the lifting lug, and the first driving part drives the blocking plate to rotate along the axis of the pin.

[0017] Furthermore, the outer cylinder is provided with two opposing clamping plates, a second drive unit connected between the two clamping plates, and a flexible protective cover fixedly connected to the clamping plates.

[0018] The flexible protective cover covers the outside of the outer cylinder, and the second driving unit drives the two clamping plates to move closer to or away from the outer cylinder.

[0019] Furthermore, the two second drive units are respectively disposed on both sides of the clamping plate, and the outer cylinder is provided with a support plate for fixing the second drive units.

[0020] Furthermore, one of the clamping plates is provided with a connecting plate, which is sleeved on the power output shaft of the first driving part. When the power output shaft of the first driving part moves up and down, the two clamping plates move away from the outer cylinder, and the clamping plates and the flexible protective cover move up and down along the axial direction of the lower output pipe.

[0021] The flexible shield is made of elastic material.

[0022] Compared with the prior art, this utility model has the following advantages:

[0023] The quantitative filling device for concrete admixture production described in this utility model uses a quantitative conveying component at the outlet end of a screw conveyor to quantitatively convey the admixture. A weighing component is installed below the vibrating component to weigh the admixture conveyed to the vibrating component again to verify its weight. If the weight is found to be insufficient or exceeds the set value, measures are taken to adjust the amount of admixture, so as to achieve accurate metering requirements before mixing and ensure the performance of concrete.

[0024] Meanwhile, by installing a blocking plate at the outlet end of the lower output pipe, the blocking plate can be driven to seal or open the outlet of the lower output pipe, allowing for secondary filling when the weighing component fails to measure the admixture, thus achieving automatic filling. Furthermore, the blocking plate at the outlet of the lower output pipe prevents dust from floating due to admixture leakage during the feeding process, ensuring a safe working environment.

[0040] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] This embodiment relates to a quantitative filling device for the production of concrete admixtures. Overall, as follows... Figure 1 As shown, the filling device includes a base frame 1, an admixture buffer tank 2 mounted on the base frame 1, and a screw conveyor 3, a metering conveying assembly 4, a vibration assembly 5, and a mixing tank 6 connected in sequence. The inlet of the screw conveyor 3 is located at the outlet of the admixture buffer tank 2.

[0042] Below the vibration assembly 5 is a weighing assembly 7, and below the weighing assembly 7 is a support base 8, the height of which is adjustable from that of the base frame 1. The quantitative delivery assembly 4 includes an upper connecting pipe 401, a lower output pipe 402, and a quantitative valve 403 connecting the upper connecting pipe 401 and the lower output pipe 402. A pivotally connected plug plate 404 is provided at the outlet end of the lower output pipe 402. After the additive is quantitatively delivered into the lower output pipe 402, the plug plate 404 is driven to open the outlet of the lower output pipe 402, and the weighing assembly 7 weighs the additive falling onto the vibration assembly 5.

[0043] The quantitative filling device for concrete admixture production in this embodiment uses a quantitative conveying component 4 installed at the outlet end of the screw conveyor 3 to quantitatively convey the admixture, and a weighing component 7 installed below the vibration component 5 to weigh the admixture conveyed to the vibration component 5 again to verify the weight. If the weight is found to be insufficient or exceeds the set value, measures are taken to adjust the amount of admixture to achieve accurate metering requirements before mixing and ensure the performance of concrete.

[0044] Meanwhile, by installing a blocking plate 404 at the outlet end of the lower output pipe 402, the blocking plate 404 can be driven to block or open the outlet of the lower output pipe 402. This allows for secondary filling when the weighing component 7 fails to measure the admixture, thus achieving automatic filling. Furthermore, the blocking plate 404 at the outlet of the lower output pipe 402 prevents dust from floating due to admixture leakage during the feeding process, ensuring a safe working environment.

[0045] Based on the above overall description, this embodiment presents an exemplary structure of a quantitative filling device for producing concrete admixtures, such as... Figure 1 and Figure 2 As shown, this device is part of the equipment used in the production of ready-mixed concrete mortar, mainly for controlling the addition process of admixtures.

[0046] In this embodiment, the support base 8 is L-shaped, and the base frame 1 is provided with a mounting plate. The mounting plate has several elongated slots along the height direction of the base frame 1. Bolts are connected to the support base 8, passing through the elongated slots, and are fixed and locked with nuts. By adjusting the height position of the support base 8 relative to the base frame 1, the height position between the outlet end of the transmission track 502 and the inlet end of the additive in the mixing tank 6 can be adjusted, improving installation flexibility.

[0047] As a preferred embodiment, such as Figure 1 and Figure 2 As shown, the vibration assembly 5 includes a vibrator 501 and a transmission track 502 connected to the vibration end of the vibrator 501. The lower output pipe 402 is located directly above the transmission track 502. In this embodiment, the vibrator 501 is a straight vibrator, and the transmission track 502 is formed into a rectangular box structure and fixed to the vibration end of the straight vibrator.

[0048] Furthermore, such as Figure 2As shown, the vibrator 501 has a fixed plate 503 at its lower end. The weighing assembly 7 includes several load cells 701 evenly distributed on the fixed plate 503. The fixed plate 503 has several mounting portions 5031 for fixing the load cells 701. In this embodiment, the mounting portions 5031 are threaded holes on the fixed plate 503, and the fixed plate 503 is bolted to the load cells 701. One end of the load cell 701 is connected to the fixed plate 503, and the other end is fixed to the support base 8. In this embodiment, the fixed plate 503 is formed into a circular sheet structure. The load cell 701 converts the weight signal into a measurable electrical signal and mainly includes an elastic metal foil sheet and an electrical measuring circuit, using a column-type sensor.

[0049] The metering valve 403 in this embodiment is a powder dispensing valve. Its working principle is to start the drive device to open the valve, and the material enters the valve body from the feed port. The material is controlled by gravity and the metering device inside the valve body and enters different discharge ports according to the preset ratio. When the material distribution reaches the set weight or time, the drive device closes the valve and stops the material distribution. The drive device can be a motor or a cylinder.

[0050] After the admixture is dispensed through the metering valve 403, it flows through the lower conveying pipe to the upper part of the transmission track 502. The weighing sensor 701 weighs the admixture and compares it with the set weight. If the weight error does not exceed the threshold, the admixture is conveyed to the mixing tank 6 by the vibratory mixer. If there is a weight error, the vibratory mixer needs to be stopped, and the admixture in the transmission track 502 needs to be manually added or reduced.

[0051] As a preferred embodiment, such as Figures 3 to 4 As shown, the lower output pipe 402 includes an outer cylinder 4021 and an inner cylinder 4022 connected in an inner and outer sleeve. A plug plate 404 is pivotally connected to the bottom end of the inner cylinder 4022. The outer cylinder 4021 is fixedly connected below the metering valve 403. The inner cylinder 4022 is correspondingly disposed at the outlet of the metering valve 403, and the additive is transported through the inner cylinder 4022. In this embodiment, the plug plate 404 is formed as a box with an open top, and the inner diameter of the plug plate 404 is adapted to the outer diameter of the inner cylinder 4022.

[0052] The quantitative filling device in this embodiment is also equipped with a PLC controller. The quantitative valve 403 and the weighing sensor 701 are electrically connected to the PLC controller. The first drive unit 4023 and the second drive unit 10 are electrically connected to the PLC controller. When the weighed additive is insufficient, the insufficient amount can be supplemented by adjusting the metering value of the quantitative valve 403, thereby realizing the function of automatic material replenishment.

[0053] In addition, Benru Figures 3 to 4As shown, a first drive unit 4023 is provided on the outer side of the outer cylinder 4021. The power output end of the first drive unit 4023 is connected to a connecting rod 4024, which is fixedly connected to the blocking plate 404. A lifting lug 4025 is provided on the outer side of the bottom end of the inner cylinder 4022. A pin 4026 is provided on the blocking plate 404, which is inserted into the lifting lug 4025. The first drive unit 4023 drives the blocking plate 404 to rotate along the axis of the pin 4026. The first drive unit 4023 is a telescopic cylinder, and the piston rod of the telescopic cylinder is hinged to the connecting rod 4024. The pin 4026 is inserted into the lifting lug 4025, and the connecting rod 4024 is connected to the piston rod at an angle. When the piston rod of the first drive unit 4023 moves up and down, it controls the opening and closing of the blocking plate 404.

[0054] To further reduce dust caused by additives falling onto the transport track 502, such as Figures 3 to 4 As shown, two opposing clamping plates 9 are provided on the outer side of the outer cylinder 4021, a second driving part 10 is connected between the two clamping plates 9, and a flexible protective cover 11 is fixedly connected to the clamping plates 9. The flexible protective cover 11 covers the outer side of the outer cylinder 4021, and the second driving part 10 drives the two clamping plates 9 to move closer to or away from the outer cylinder 4021. In this embodiment, the flexible protective cover 11 can be a conical rubber sleeve or a cloth cover. When the two clamping plates 9 abut against the outer cylinder 4021, the flexible protective cover 11 is squeezed to form a protective cover for the bottom end of the inner cylinder 4022, thereby effectively reducing dust caused by the falling additive.

[0055] Furthermore, such as Figure 4 As shown, two second drive units 10 are respectively disposed on both sides of the clamping plate 9, and a support plate 12 for fixing the second drive units 10 is provided on the outer cylinder 4021. In this embodiment, the second drive unit 10 is a telescopic cylinder, and the telescopic cylinder is a double-rod cylinder, so as to drive the two opposing clamping plates 9 simultaneously. The protective cover is fixed to the clamping plate 9 by bolts or set screws.

[0056] In addition, in this embodiment, one of the clamping plates 9 is provided with a connecting plate 13. The connecting plate 13 is sleeved on the power output shaft of the first drive part 4023. When the power output shaft of the first drive part 4023 moves up and down, the two clamping plates 9 move away from the outer cylinder 4021. The clamping plates 9 and the flexible cover 11 move up and down along the axial direction of the lower output pipe 402. The flexible cover 11 is made of elastic material.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
