Description

Technical Field

[0001] This utility model relates to the field of pre-cooled concrete technology, specifically to an intelligent air-cooled silo. Background Technology

[0002] Pre-cooled concrete is a special concrete pouring technique that reduces internal temperature stress in the concrete by lowering its initial pour temperature, thereby improving its pourability. This technique is typically used in hot summers or for large-volume concrete pours to ensure quality and stability. During pre-cooled concrete production, aggregate temperature is a crucial factor affecting concrete quality. High-temperature aggregates can lead to accelerated slump loss, reduced strength, and increased cracking. Traditional aggregate cooling methods primarily involve water spraying, but this method suffers from drawbacks such as water waste, difficulty in controlling aggregate moisture content, and susceptibility to freezing in winter.

[0003] To address this issue, existing technologies employ air-cooling techniques to cool aggregates. For instance, utility model patent CN210025821U discloses an air-cooled aggregate silo structure. This structure utilizes rectangular air inlet and outlet ducts within the silo to create convection currents in the internal cooling air, offering advantages such as simple structure and high cooling air utilization efficiency. However, during operation, existing technologies often involve discharging materials through hoppers inserted into the silo inlet. The irregular shape of these hoppers makes sealing difficult, leading to significant dust emissions and environmental pollution. Utility Model Content

[0028] With reference to the accompanying drawings, the technical solutions in the embodiments of the present application will be described clearly and completely. Those skilled in the art should know that the embodiments described below are only part of the embodiments of the present disclosure, not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of the present application.

[0029] The present scheme is provided with a flap system, a reset system 22 and a slow descent system. When the aggregate falls, the aggregate falls on the flap door 21, and the reset structure is pried by the weight of the aggregate plus the weight of the flap, the flap door 21 is opened, and the aggregate falls into the bin. During the falling process of the aggregate, when the flap door 21 is blocked, the anti-blocking mechanism 24 is started, and the flap door 21 is shaken by the anti-blocking mechanism 24 to solve the blocking problem. In addition, when the aggregate falls, it is buffered by the slow descent mechanism 25 to reduce its gravitational potential energy and avoid damaging the refrigeration equipment.

At the same time, the water content detection can automatically match the water quantity for concrete mixing, realize the adaptation and connection of upstream and downstream processes, and realize automatic and intelligent production.

[0031] After introducing the basic principle of the present application, the various non-limiting embodiments of the present application will be specifically introduced. Any element quantity in the drawings is used for example and not for limitation, and any naming is only used for distinction and does not have any limiting meaning.

[0032] The principle and spirit of the present application will be explained in detail below with reference to several representative embodiments of the present application. Embodiment

[0033] An intelligent air-cooled bin, such as Figures 1-5As shown, including the bin body 1, bin body 1 from top to bottom in turn provided with the feed inlet 11, return air duct 12, air inlet 13 and discharge hopper 14, feed inlet 11 is provided with a self-closing system 2 for sealing, the self-closing system 2 includes a pair of flap door 21, wherein one end of the flap door 21 is fixedly installed with the pivot 211, the pivot 211 is rotatably installed on the top of the feed inlet 11 through the base 212 and the clamp 213, to ensure that the flap door 21 can rotate around the axis direction of the pivot 211.

[0034] As shown in the drawings, Figures 3-4 The flap door 21 is connected with a reset system 22, the reset system 22 includes a plurality of connecting rods 221, one end of the connecting rod 221 is fixedly connected with the pivot 211 along the radial direction of the pivot 211, the other end of the connecting rod 221 is threadedly installed with a plurality of counterweights 222, the counterweight 222 is provided with a fastening screw, which is convenient for adjusting and fixing the position of the counterweight 222 on the connecting rod 221, when the position of the counterweight 222 is adjusted to achieve the ideal state of opening the door for discharging and closing the door after stopping discharging, the position of the counterweight 222 is fixed by using the fastening screw to prevent the center of gravity from shifting.

[0035] Specifically, a pair of flap doors 21 are rotatably installed on the two sides of the feed inlet 11 through the pivot 211, and the flap door 21 can rotate around the axis of the pivot 211; the pivot 211 is fixedly installed with the connecting rod 221 along the radial direction thereof, and the connecting rod 221 is threadedly installed with the counterweight 222. When the counterweight 222 is reset, the flap door 21 is pried closed through the connecting rod 221 and the pivot 211, at this time, the end of the flap door 21 away from the pivot 211 abuts against each other to achieve the purpose of sealing, at the same time, the flap door 21 is located inside the bin, and the upper surface of the flap door 21 is in the shape of an inverted triangle, leaving a sinking space for the head of the belt conveyor when feeding.

[0036] The working process is as follows: when the aggregate falls, the aggregate falls on the flap door 21, and the flap door 21 is opened by the weight of the aggregate and the weight of the flap, and the aggregate falls into the bin. When the discharging is stopped, the reset structure relies on its own reset ability to automatically tightly close the flap door 21.

[0037] As shown in the drawings, Figures 3-5 The upper surface of the flap door 21 is fixedly installed with a wear-resistant lining plate 23, the wear-resistant lining plate 23 adopts a double-layer structure of high-manganese wear-resistant steel plate 231 and high-molecular plate 232, wherein the high-manganese wear-resistant steel plate 231 is the bottom plate, and the upper high-molecular plate 232 is an ultrahigh-molecular polyethylene plate;

[0038] The high manganese wear-resistant steel plate 231 and the polymer plate 232 are connected in the form of a countersunk screw, which improves the service life of the lining plate and allows the lining plate group to be easily replaced, facilitating later maintenance. At the bottom of the wear-resistant bottom plate, a layer of rubber-plastic insulation board 233 is attached, which can effectively insulate the heat exchange inside and outside the bin and reduce the energy loss inside the bin.

[0039] The bottom surface of each flap door 21 is fixedly installed with an anti-blocking mechanism 24. In this embodiment, the anti-blocking mechanism 24 is a ball-type pneumatic vibrator. Through electronic monitoring 3 for comparison and detection, when the aggregate is stuck in the middle of the two flap doors 21, the flap doors 21 cannot be smoothly opened and closed. At this time, the external control system will start the anti-blocking mechanism 24, which will cause the flap doors 21 to shake through the excitation effect of the vibrator, thereby handling the occurrence of aggregate blocking.

[0040] As shown in Figures 1-2 The bottom of the flap door 21 is provided with a slow descent mechanism 25, which is fixedly installed inside the bin. The slow descent mechanism 25 can be fixedly installed with the top plate of the feed inlet 11 and the inner wall around the bin.

[0041] The slow descent mechanism 25 can reduce the falling speed of the aggregate in the bin, prevent large aggregate from falling too fast and breaking, and reduce the aggregate particle size, which affects the proportioning of finished concrete. At the same time, the device can prevent the falling aggregate from damaging the air inlet 13 and air return 12 inside the bin body 1. The slow descent mechanism 25 can also prevent material segregation. In this embodiment, the slow descent mechanism 25 is a prior art, such as a slow descent plate, a slow descent ladder, or a slow descent frame, which will not be described in detail here.

[0042] In this embodiment, the bin body 1 is a steel structure or a concrete structure. When a steel structure is used, the air inlet 13 and the air return 12 are fixedly connected to the inner wall of the bin body 1 at both ends. When a concrete structure is used, the air inlet 13 and the air return 12 are placed in a resting manner to improve the stability and sealing of the air duct. The outer wall of the above-mentioned steel structure or concrete structure bin body 1 is covered with an insulation layer 18.

[0043] In addition, the two side walls of the air inlet 13 are fixedly installed with a rotatable louver fan 15, and the inner wall of the bin body 1 is fixedly installed with an adjusting motor 16. The adjusting motor 16 is fixedly connected to the louver fan 15 for adjusting the opening angle and size of the louver fan 15 to adjust the air output. The air inlet 13 has a plurality of ventilation holes at the upper part, which is beneficial to the passage of cold air and prevents the aggregate from entering the air duct and blocking, ensuring uniform air output. The air inlet 13 is provided with a wind guide groove 17 to ensure that the cold air can reach the side away from the air cooler, avoiding the situation that the aggregate temperatures at both ends are inconsistent.

[0044] As shown in Figures 1-2As shown, the top surface of the bin inlet is also fixedly installed with an electronic monitor 3 and a radar material level meter 4, and temperature sensors 5 are fixedly installed at the air return opening of the air return duct 12 and the air inlet opening of the air inlet duct 13, and a water content detection device 6 is also fixedly installed at the discharge hopper 14, and the electronic monitor 3, the radar material level meter 4, the temperature sensors 5 and the water content detection device 6 are connected with an external control system.

[0045] The electronic monitor 3 is used for real-time comparative analysis of detection of the discharging speed, the thickness of the wear-resistant lining plate 23, the opening and closing state of the flap door 21 and the like, and the corresponding parameters such as the discharging speed and the opening and closing of the anti-blocking mechanism 24 are adjusted through the external control system, or a warning is sent to the staff. The radar material level meter 4 at the top of the bin can send a signal to the external control system in the case of lack of material or full material, and the external control system decides the operation of feeding and stopping feeding of the aggregate bin according to the signal, so that the continuous production of the concrete production system is ensured, and the occurrence of the full bin is avoided. The temperature sensors 5 transmit data to the external control system, and the external control system automatically adjusts the running power, running time and opening and closing size of the louver fan 15 of the air inlet duct 13 according to the preset temperature range, so that the purpose of accurate cooling is achieved, the temperature of the aggregate is ensured to reach the standard, the overcooling is avoided, the operation cost is saved, and the product quality is improved. The water content detection device 6 at the bottom of the bin is used for detecting the water content of the sand during discharging, and the external control system automatically adjusts the amount of water for stirring according to the measurement result and the concrete proportioning.

[0046] The above-mentioned electronic monitor 3, radar material level meter 4, temperature sensors 5 and water content detection device 6 are prior art, and will not be described here.

[0047] The working process of the scheme is as follows: the aggregate enters the bin body 1 from the feeding opening 11, the feeding opening 11 is provided with a self-opening and closing system 2, which can ensure that the feeding is automatically opened and the feeding is automatically closed, and the heat exchange between the inside and outside of the bin is maximally avoided. The cold air enters the bin from the air inlet duct 13 and is discharged to the external exchanger from the air return duct 12; the aggregate in the bin is cooled by the circulation of the cold air. The rotatable louver fan 15 is arranged on both sides of the air inlet duct 13, and the size of the opening and closing of the louver fan 15 is used to control the uniform distribution of the cold air flow organization, so that the undercooling and overcooling of the aggregate are avoided in the case of normal, balanced and continuous production.
