Description

Technical Field

[0001] This invention relates to the field of concrete pouring technology, specifically a civil engineering concrete cooling device. Background Technology

[0002] Because large-volume concrete generates high temperatures during hydration after pouring, and the heat accumulates inside and dissipates slowly, the internal temperature rises significantly while the external concrete dissipates heat quickly, resulting in a large temperature difference between the inside and outside. This can easily lead to temperature-induced cracks. Therefore, measures need to be taken during concrete construction to control the concrete temperature and prevent problems such as cracks and deformation caused by excessively high temperatures.

[0003] To ensure that the temperature of the concrete is within the specified range when it is poured into the formwork, it must be cooled to below the specified temperature before being loaded into the cement truck. This ensures that the concrete slurry can maintain the specified temperature for pouring into the formwork even after long-term transportation.

[0004] Ice cooling is an important and efficient method for reducing the temperature of concrete. During the concrete production process, adding a certain amount of ice to the concrete can quickly lower its temperature, thereby preventing problems such as cracks and deformation.

[0005] Specifically, in the concrete preparation process, ice is added to the conveyor belt transporting aggregates to cool them down. The melted ice water can replace room temperature water and be mixed with cement and aggregates to produce pre-cooled concrete at a lower temperature. However, the current method of mixing ice and aggregates involves directly setting up a conveyor channel for transporting ice on the aggregate conveyor belt. Ice is added directly to the aggregates through this channel and transported together with the aggregates. Both the conveyor belt and the ice channel are in direct contact with the high-temperature external environment. This not only results in a high temperature for the conveyor belt itself, but also a rapid temperature rise after the ice melts, leading to poor cooling effect on the aggregates and directly affecting the temperature of the prepared pre-cooled concrete mortar. Summary of the Invention

[0006] The purpose of this invention is to provide a civil engineering concrete cooling device that cuts ice blocks into ice shavings. The cut ice shavings are then fed into a conveyor belt, a first cooling section, and a second cooling section. The ice shavings in the first and second cooling sections can cool the conveyor belt body, keeping it at a low temperature. This allows the ice shavings to maintain a low temperature and fully cool the aggregate, ensuring that the temperature of the mixed concrete mortar meets the specified range.

[0007] The technical solution of this invention is:

[0011] Furthermore, the ice handling and supporting part includes: a first housing, which is tubular, with multiple ice inlets on the side of the first housing, and is connected to the ice outlet of the ice maker through the ice inlets; an ice handling plate, which is disposed at the bottom of the first housing and is used to carry the ice entering the first housing, and multiple sets of ice outlet grooves are formed on the ice handling plate.

[0012] Furthermore, the lines connecting the multiple ice outlet grooves in each group form a ring. The ring radius formed by each group of ice outlet grooves is different and is arranged concentrically with the ice processing tray. The ice outlet groove includes: a channel, which is formed on the tray body of the ice processing tray, and the channel is an arc-shaped channel; a cutting blade, which is an arc-shaped blade, is set at one end of the channel. The two ends of the cutting blade are connected to the two sides of the channel, the arc-shaped part protrudes from the tray surface of the ice processing tray, and the blade part faces the other end of the channel.

[0013] Furthermore, the ice processing movable part includes: a second housing, corresponding to the position of the first housing, with a connecting column extending through the top and bottom of the second housing and rotating vertically along its central axis; a turntable, with one end of the connecting column connected at its center, the turntable rotating on the top surface of the second housing; a drill bit, including an ice-drilling end and a connecting end, the connecting end being connected to the other end of the connecting column, the ice-drilling end corresponding to and structurally matching the ice processing plate; a movable part drive component, disposed between the second housing and the first housing, for driving the second housing to move closer to and away from the first housing along the height direction; and a drill bit drive component, disposed between the second housing and the first housing, for driving the drill bit to rotate through the movement of the second housing along the height direction.

[0014] Furthermore, the driving component of the movable part is a hydraulically controlled telescopic rod, and the drill bit driving component includes: a lead screw, which is vertically disposed on the top of the first housing; a threaded sleeve, which is rotatably sleeved on the lead screw, and the threaded sleeve is disposed on the side of the second housing through a limiting and fixing component, and a transverse groove is formed on the side of the second housing; a gear, which is sleeved on the threaded sleeve, and one end enters the second housing through the transverse groove; and a gear ring, which is sleeved on the connecting column and meshes with the gear.

[0015] Furthermore, the ice-drilling end of the drill bit is a spherical surface, and the ice-handling plate is a spherical groove that matches the ice-drilling end of the drill bit. The drill bit also includes: a plurality of fixing blades disposed on the spherical surface of the drill bit, and the cutting edge of each fixing blade is serrated for fixing ice blocks.

[0016] Furthermore, the top of the first housing is provided with multiple limiting members, which move up and down synchronously to control the descent distance of the second housing.

[0017] Furthermore, the center of the ice processing plate is set as a horizontal part, and a protrusion is provided in the horizontal part. The center of the ice-drilling end of the drill bit is provided with a receiving groove that matches the protrusion.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention utilizes the cooperation between the ice-handling support section and the ice-handling moving section to continuously cut easily melting ice shavings from the ice. A large portion of the cut ice shavings enters the conveyor belt spirally arranged between the first and second cooling sections, covering the aggregate being transported on the conveyor belt. As the ice shavings cover the aggregate, they melt rapidly, carrying away heat from the aggregate surface and quickly cooling the aggregate. Since the aggregate slides down the conveyor belt, the temperature of the conveyor belt itself also affects the cooling of the aggregate. Therefore, this invention provides sandwich layers in both the first and second cooling sections, namely the first sandwich layer and the second sandwich layer. The remaining portion of the cut ice shavings enters the first and second sandwich layers to cool the conveyor belt body, ensuring a low-temperature environment for the conveyor belt itself. This, in turn, ensures that the ice shavings covering the aggregate remain at a low temperature, making the cooling and heat preservation effect of the ice shavings on the aggregate more durable.

[0020] This invention uses an insulation cover to make the pumping section and the ice block introduction section relatively sealed, which can isolate most of the external heat and enable the ice shavings in the pumping section and the ice blocks in the ice block introduction section to achieve the maximum cooling effect.

[0021] The drill bit and ice processing disc of the present invention are structurally matched, and the ice blocks entering the ice processing disc are all located on the spherical surface of the ice processing disc located around the protrusion block through the action of the central protrusion and the receiving groove. This makes it easier for the fixing edge on the ice-drilling end of the drill bit to contact and fix the ice blocks, so that the ice blocks can pass through the ice exit groove more smoothly and be cut into ice sand.

[0032] The following is in conjunction with the appendix Figure 1 To the attached Figure 9 The specific embodiments of the present invention will be described in detail below. In the description of the present invention, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0033] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this invention, unless otherwise stated, "a plurality of" means two or more. Example

[0034] like Figure 1 As shown, a civil engineering concrete cooling device includes: a pumping unit 1 and an ice block introducing unit; as Figure 2As shown, the pumping unit 1 includes: a first cooling unit 2, a second cooling unit 3, and a conveyor belt 4. The first cooling unit 2 has an inlet groove near the top and an outlet groove near the bottom for the conveyor belt 4 to pass through and exit. The first cooling unit 2 has a first interlayer 21 inside. The second cooling unit 3 is fitted inside the first cooling unit 2, and a space interlayer is separated between the first cooling unit 2 and the second cooling unit 3. The space interlayer is used to install the conveyor belt 4, and the second cooling unit 3 has a second interlayer 31 inside. The conveyor belt 4 is used to transport aggregate. One end of the conveyor belt 4 enters the space interlayer from the inlet groove and extends from the top of the side of the second cooling unit 3 to the bottom of its side. It extends out from the outer side of the first cooling unit 2 from the outlet groove. One side of the conveyor belt 4 is the inner wall of the first cooling unit 2, and the other side is the outer wall of the second cooling unit 3. Stone is input at the top end of the conveyor belt 4. The ice block introduction unit includes: an ice block handling bearing unit 5 and an ice block handling moving unit 6. The ice processing support unit 5 is used to process ice blocks into slush and transport them to the pumping unit 1. The ice processing support unit 5 is located on the top of the pumping unit 1 and is connected to the ice maker. It is used to carry the ice blocks transported by the ice maker. The size of the ice blocks can be set according to the actual situation. If the weather temperature is high, the ice blocks will be made larger to prevent the ice blocks from melting before entering the pumping unit 1. The bottom of the ice processing support unit 5 is provided with multiple sets of ice outlet grooves 53, which are respectively connected to the first interlayer 21, the second interlayer 31 and the conveyor belt 4. The ice processing moving part 6 is located on the top of the ice processing support unit 5 and is used to grind large ice blocks into slush. After grinding, the slush enters the conveyor belt 4 from the ice outlet groove 53 to cool the surface of the aggregate. After grinding, the slush enters the first interlayer 21 and the second interlayer 31 from the ice outlet groove 53 to cool the frictional heat generated in the conveyor belt 4 due to the rolling friction of the aggregate against the side of the conveyor belt 4.

[0035] In some embodiments, in order to improve the cooling effect of the cooling section on the sides and body of the conveyor belt 4, and to reduce the central space occupied by the conveyor belt 4, such as Figure 2 As shown, the first cooling section 2 is tubular, the second cooling section 3 is cylindrical, and the conveyor belt 4 is arranged in a spiral on the side of the second cooling section 3. Compared with the straight conveyor belt 4, the spiral arrangement can not only prolong the cooling time of the ice sand on the aggregate, but also allow the aggregate to be fully cooled before being mixed with cement, so that the prepared concrete mortar reaches a better temperature range. At this time, the space between the inner side of the first cooling section 2 and the outer side of the second cooling section 3 is equivalent to a cooling chamber. Moreover, the ice sand flowing in the first interlayer 21 and the second interlayer 31 melts and absorbs heat, which can reduce the frictional heat generated on the side of the conveyor belt 4, thereby further ensuring the cooling effect of the aggregate.

[0036] In some embodiments, the melted ice water from the first interlayer 21 and the second interlayer 31 is drained and mixed with the aggregate in the conveyor belt 4, replacing the mixing of room temperature water and cement, to achieve the effect of pre-cooling the concrete, such as... Figure 2 and Figure 6 As shown, it also includes: a first water collection platform 23, a second water collection platform 32, and a connecting channel array 10. The first water collection platform 23 is located at the bottom of the first interlayer 21 of the first cooling section 2. The top of the first water collection platform 23 is aligned with the side trajectory of the conveyor belt 4 in a spiral loop at the bottom. Multiple water outlets 33 are opened on the side of the first cooling section 2 along the trajectory of the first water collection platform 23 to allow the ice water from the melting of the cooling sand in the first interlayer 21 to flow out into the conveyor belt 4. The second water collection platform 32 is located at the bottom of the second interlayer 31 of the second cooling section 3. The top of the second water collection platform 32 is aligned with the other side trajectory of the conveyor belt 4 in a spiral loop at the bottom. Multiple water outlets 33 are opened on the side of the second cooling section 3 along the trajectory of the second water collection platform 32 to allow the ice water from the melting of the cooling sand in the second interlayer 31 to flow along the water outlets 33 into the conveyor belt 4 to mix with the stone again and cool the surface of the stone. Figure 6 As shown, a connecting channel array 10 is provided between the first mezzanine 21 and the first water accumulation platform 23, and a connecting channel array 10 is provided between the second mezzanine 31 and the second water accumulation platform 32. Figure 6 The diagram illustrates one type of array arrangement of connecting channels. In actual design and production, it is sufficient to separate and transport the melted ice water and ensure that the ice water covers the sides of the first and second cooling sections.

[0037] In some embodiments, the ice handling support unit 5 includes: a first housing and an ice handling tray 52. ​​The first housing is tubular, and multiple ice inlets 51 are provided on the side of the first housing, which are connected to the ice outlet of the ice maker. The ice handling tray 52 is located at the bottom of the first housing and is used to carry ice blocks entering the first housing. Multiple sets of ice outlet grooves 53 are provided on the ice handling tray 52. ​​In actual design, in order to allow ice blocks to gather on the ice handling tray 52, an inclined surface 54 is provided between the ice handling tray 52 and the inner side of the first housing. Ice blocks that enter the first housing through the ice inlets 51 slide down the inclined surface 54 onto the ice handling tray 52.

[0038] like Figure 4 and Figure 5As shown, the lines connecting the multiple ice outlet grooves 53 in each group form a ring. The radius of the ring formed by each group of ice outlet grooves 53 is different and they are arranged concentrically with the ice processing tray 52. ​​The ice outlet groove 53 includes a channel 531 and a cutting blade 532. The channel 531 is formed on the tray body of the ice processing tray 52 and is an arc-shaped channel. The cutting blade 532 is an arc-shaped blade, located at one end of the channel 531. The two ends of the cutting blade 532 are connected to the two sides of the channel 531. The arc-shaped part protrudes from the tray surface of the ice processing tray 52. At the other end of the channel 531, ice blocks are conveyed to the ice block processing tray 52. ​​The ice block is pressed down by the ice block processing movable part 6, which holds the ice block in place and allows it to slide along the channel 531. When the ice block passes through the cutting blade 532, a layer of ice sand is cut off from the bottom of the ice block, and it slides down through the channel 531 onto the corresponding first interlayer 21, second interlayer 31, or conveyor belt 4. An inclined connecting part 22 is provided between the outer side of the first cooling part and the top of the first interlayer 21, so that the ice sand can slide smoothly down into the first interlayer 21 along the inclined connecting part 22.

[0039] In some embodiments, to make it easier for the ice handling movable part 6 to press and slide the ice, such as... Figure 2 As shown, the ice processing unit 6 includes: a second housing, a turntable 71, a drill bit 7, a moving part drive 9, and a drill bit drive 8. The second housing corresponds to the position of the first housing. A connecting column 73, which passes through the top and bottom, is vertically rotatable at the central axis of the second housing. The center of the turntable 71 is connected to one end of the connecting column 73, and the turntable 71 rotates on the top surface of the second housing. The drill bit 7 includes an ice-drilling end and a connecting end, which are connected to the other end of the connecting column 73. The ice-drilling end corresponds to the position of the ice processing plate 52 and is structurally matched. The moving part drive 9 is disposed between the second housing and the first housing and is used to drive the second housing to move closer to and away from the first housing along the height direction. The drill bit drive 8 is disposed between the second housing and the first housing. Through the movement of the second housing along the height direction, the drill bit 7 is driven to rotate, thereby pressing the ice block to slide along the ice outlet groove 53 and cutting out ice shavings.

[0040] To facilitate control of the movable part drive component 9, which is a hydraulically controlled telescopic rod, a drill bit drive component 8 is designed to work in conjunction with the movable part drive component 9. This allows the drill bit drive component 8 to obtain the power to drive the drill bit 7 through the drive of the movable part drive component 9, as shown in Figure 2. Figure 3As shown, the drill bit drive component 8 includes: a lead screw 81, a threaded sleeve 82, a gear 83, and a gear ring 74. The lead screw 81 is vertically mounted on the top of the first housing. The threaded sleeve 82 can rotate on the lead screw 81 and be fed by the lifting and lowering of the second housing. The threaded sleeve 82 is mounted on the side of the second housing by a limiting and fixing component, and a transverse groove is opened on the side of the second housing. The gear 83 is sleeved on the threaded sleeve 82, and one end enters the second housing through the transverse groove. The gear ring 74 is sleeved on the connecting post 73 and meshes with the gear 83. The second housing is lifted and lowered by the movable drive component 9. The threaded sleeve 82 rotates on the lead screw 81 while the second housing is lifted and lowered, so as to drive the gear 83 on it to rotate, thereby driving the gear ring 74 to rotate. As the second housing approaches the first housing, the drill bit 7 gradually approaches the ice block processing disk 52 while maintaining rotation, thereby pressing and fixing the ice block and pressing and sliding it, cutting out ice shavings more quickly.

[0041] like Figure 2 and Figure 3 As shown, the ice-drilling end of the drill bit 7 is a spherical surface, and the ice-handling plate 52 is a spherical groove that matches the ice-drilling end of the drill bit 7. The drill bit 7 also includes multiple fixing blades 72, which are disposed on the spherical surface of the drill bit 7. Each fixing blade 72 has a serrated cutting edge for fixing ice. The number of fixing blades 72 can be set according to the size of the ice. When the ice is large, fewer fixing blades 72 can be set. Conversely, when the ice is small, the number of fixing blades 72 can be increased so that the fixing blades 72 can effectively abut against the surface of the ice.

[0042] Because ice blocks vary in size, the distance between the spherical surface of the drill bit and the ice-holding plate is controlled so that the fixing edge 72 on the drill bit 7 can precisely abut the ice block against the ice-holding plate. This prevents the distance from being too close, which would crush the ice block, and from being too far, which would prevent the ice block from being held firmly. Figure 1 As shown, the top of the first housing is provided with multiple limiting members 55, which move up and down synchronously to control the descent distance of the second housing. Example

[0043] The difference from Example 1 is that, in this example, in order to keep the ice in the ice handling support unit 5 warm, such as... Figure 7 As shown, a heat insulation cover 57 is fitted over the outside of the first housing. The heat insulation cover 57 covers the second housing and the first housing inside. A sealing strip is provided between the heat insulation cover 57 and the first housing to improve the internal heat insulation effect. A channel is reserved on the outside of the heat insulation cover 57 so that the ice outlet end of the ice maker can be connected to the ice block inlet 51. The heat insulation cover 57 can isolate a part of the external high temperature air to ensure that the ice blocks inside the ice block processing bearing part 5 will not melt quickly, thereby affecting the quality of the ice slush, so that the ice slush can melt and absorb heat after reaching the pumping part 1. Example

[0044] The difference from Example 2 is that, as Figure 8 As shown, the center of the ice processing tray 52 is set as a horizontal part, and a protrusion 56 is provided in the horizontal part. The center of the ice-drilling end of the drill bit 7 is provided with a receiving groove 75 that matches the protrusion 56. This ensures that the ice blocks entering the ice processing tray 52 are all on the spherical surface of the ice processing tray 52 located around the protrusion 56, so that the fixing blade 72 on the ice-drilling end of the drill bit 7 can more easily contact and fix the ice blocks, so that the ice blocks can pass through the ice outlet groove 53 more smoothly and be cut into ice sand, and then enter the first interlayer 21, the second interlayer 31 and the conveyor belt 4. Example

[0045] The difference from Example 3 is that, as Figure 9 As shown, in order to reduce the pressure on the protrusion 56, the protrusion 56 is designed as follows: Figure 9 The example has a conical pedestal, and the receiving groove 75 is also provided with a matching shape. Multiple ball bearing slides 561 are provided on the side of the conical pedestal, and a sliding cap 562 is provided on the conical pedestal. When the receiving groove 75 abuts against the top of the conical pedestal, the friction between the two is reduced by the sliding cap 562.

[0046] The above-disclosed embodiments are merely preferred embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
