Description

Technical Field

[0001] The utility model relates to the technical field of solution dehydration and drying equipment, in particular to a water reducing agent drying device. Background Art

[0002] Water reducer is a concrete admixture that can reduce the amount of mixing water while maintaining the slump of concrete basically unchanged. Water reducer is often obtained by drying the solution, and is generally dried using a spray drying device. There are two commonly used existing spray drying devices, one is a vertical drying device and the other is a horizontal drying device. In the existing horizontal drying device, the nozzle of the drying device is generally arranged on the side wall of the horizontal drying device, spraying in the horizontal direction and blowing out hot air horizontally to achieve drying. When this horizontal drying device is used to dry some materials with high water content, because the horizontally sprayed droplets stay in the air for a short time, they may fall to the bottom of the drying device before they are completely dried, which easily causes insufficient drying and leads to agglomeration. In order to solve this problem, the existing treatment method is to reduce the spray volume, increase the air outlet and increase the temperature of the hot air, which not only consumes a lot of energy but also leads to low production efficiency, increasing the production cost of the water reducer.

[0003] In summary, there is an urgent need for a water reducing agent drying device to solve or at least partially solve the problems existing in the prior art. Utility Model Content

[0004] The utility model aims to provide a water reducing agent drying device, aiming to solve the problem of insufficient drying when drying materials with high water content in the prior art. The specific technical scheme is as follows:

[0005] A water reducing agent drying device comprises a box body, an air supply mechanism, an exhaust mechanism, a spray mechanism and a liquid supply mechanism, wherein the spray mechanism is arranged on the side wall of the box body, and the spray mechanism can be connected to the box body in a pitching and rotatable manner, and the inlet end of the spray mechanism is arranged outside the box body, and the outlet end of the spray mechanism extends into the box body; the outlet end of the liquid supply mechanism is connected with the inlet end of the spray mechanism, and the outlet end of the air supply mechanism is connected with the inlet end of the spray mechanism; the first end of the exhaust mechanism is connected with the box body, and the second end of the exhaust mechanism is connected with the outside; the spray mechanism comprises a rotating frame, a liquid phase nozzle and a gas phase nozzle, and a rotating shaft is provided on the rotating frame, and the rotating frame is rotatably connected with the box body through the rotating shaft.

[0006] Furthermore, the gas phase nozzle and the liquid phase nozzle are both fixedly connected to one side of the rotating frame located in the box body, and the liquid phase nozzle and the gas phase nozzle are both arranged toward the inside of the box body.

[0007] Further, the liquid phase nozzle is arranged inside the gas phase nozzle.

[0008] Furthermore, a plurality of gas phase nozzles and a plurality of liquid phase nozzles are arranged, and the plurality of liquid phase nozzles are arranged in one-to-one correspondence with the plurality of gas phase nozzles.

[0009] Furthermore, the bottom wall of the box body is arranged inclined.

[0010] Furthermore, the bottom wall of the box body is arranged to be inclined in a direction away from the blowing mechanism.

[0011] Furthermore, the water reducing agent drying device also includes a vibration generating mechanism, and the vibration generating mechanism is installed at the bottom of the box body.

[0012] Furthermore, the water reducing agent drying device also includes a conveyor, which is arranged in the box body, and the conveyor is arranged at one end of the bottom wall of the box body away from the blowing mechanism, and a discharge port is provided on the box body corresponding to the conveyor.

[0013] Furthermore, a baffle and a dust collector are arranged in the box. The baffle is fixedly connected to the top wall inside the box and extends downward. The dust collector is installed on the top wall of the inner wall of the box and is located on the side of the baffle away from the blowing mechanism.

[0014] Furthermore, the air supply mechanism includes an air source, a heating component and an air supply pipe, and the air source, the heating component and the blowing mechanism are connected in sequence through the air supply pipe; the exhaust mechanism includes an exhaust pipe, a first end of the exhaust pipe is connected to the top of the box body, and a second end of the exhaust pipe is connected to the outside world; the liquid supply mechanism includes a liquid storage tank, an infusion pipe and an infusion pump, and the liquid storage tank, the infusion pump and the blowing mechanism are connected in sequence through the infusion pipe.

[0015] The application of the technical solution of the utility model has the following beneficial effects:

[0016] The concentrated water reducer is sprayed into the box through the spraying mechanism, the liquid phase nozzle atomizes the water reducer into fine droplets, and sprays hot air into the box through the spraying mechanism. As the water reducer droplets move in the box, the water reducer droplets continuously lose water and dry into solid powder of water reducer, which settles to the bottom of the box. When encountering a water-reducing agent with a high water content, the water in the water-reducing agent has not been completely evaporated from the time the water-reducing agent is sprayed to the bottom of the box, which can easily cause the water-reducing agent to clump at the bottom of the box. When this happens, the spraying mechanism can be rotated to spray obliquely upward of the box. The sprayed droplets first move toward the top of the box, and under the action of gravity, the speed gradually decreases and moves slowly downward. Compared with horizontal spraying, the spraying mechanism spraying obliquely upward can increase the time for the droplets to move in the box, thereby increasing the evaporation amount of the water-reducing agent droplets, so that the water-reducing agent with a high water content can be completely dried into water-reducing agent powder without reducing the spraying amount, thereby preventing the undried water-reducing agent from falling to the bottom of the box and condensing into agglomerates.

DETAILED DESCRIPTION

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below, and preferred embodiments of the present invention are given. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] Example:

[0028] See also Figure 1-Figure 5 The present embodiment provides a water reducing agent drying device, including a box body, an air supply mechanism, an exhaust mechanism, a blowing mechanism and a liquid supply mechanism. The blowing mechanism is arranged on the side wall of the box body, and the blowing mechanism can be connected to the box body in a pitching and rotatable manner. The inlet end of the blowing mechanism is arranged outside the box body, and the outlet end of the blowing mechanism extends into the box body; the outlet end of the liquid supply mechanism is connected to the inlet end of the blowing mechanism, and the outlet end of the air supply mechanism is connected to the inlet end of the blowing mechanism; the first end of the exhaust mechanism is connected to the box body, and the second end of the exhaust mechanism is connected to the outside.

[0029] Specifically, the air supply mechanism includes an air source, a heating component and an air supply pipe, and the air source, the heating component and the blowing mechanism 4 are connected in sequence through the air supply pipe; the exhaust mechanism includes an exhaust pipe, a first end of the exhaust pipe is connected to the top of the box body, and a second end of the exhaust pipe is connected to the outside, and the exhaust gas in the tank body is discharged through the exhaust pipe; the liquid supply mechanism includes a liquid storage tank, an infusion pipe and an infusion pump, and the liquid storage tank, the infusion pump and the blowing mechanism are connected in sequence through the infusion pipe, and the concentrated water reducer solution is stored in the liquid storage tank and delivered to the blowing mechanism through the infusion pump and the infusion pipe.

[0030] It should be noted that in this embodiment, the gas source is a pumping fan, and the heating component is an electric heater. The pumping fan delivers external gas to the electric heater through the air supply pipe, and the air heated by the electric heater is delivered to the spray mechanism through the air supply pipe, and sprayed into the box from the spray mechanism; in some other embodiments of the present application, the gas source can also be a compressed air tank or other component or structure that can continuously provide gas, and the heating component can also be a gas heater or other component or structure that can heat gas. Both the air supply pipe and the infusion pipe are flexible pipes to enable the rotating frame to rotate smoothly.

[0031] It can be known that the concentrated water reducer is sprayed into the box through the spraying mechanism, the liquid phase nozzle atomizes the water reducer into fine droplets, and sprays hot air into the box through the spraying mechanism. As the water reducer droplets move in the box, the water reducer droplets continuously lose water and dry into solid powder of water reducer, which settles to the bottom of the box. When encountering a water-reducing agent with a high water content, the water in the water-reducing agent has not been completely evaporated from the time the water-reducing agent is sprayed to the bottom of the box, which can easily cause the water-reducing agent to clump at the bottom of the box. When this happens, the spraying mechanism can be rotated to spray obliquely upward of the box. The sprayed droplets first move toward the top of the box, and under the action of gravity, the speed gradually decreases and moves slowly downward. Compared with horizontal spraying, the spraying mechanism spraying obliquely upward can increase the time for the droplets to move in the box, thereby increasing the evaporation amount of the water-reducing agent droplets, so that the water-reducing agent with a high water content can be completely dried into water-reducing agent powder without reducing the spraying amount, thereby preventing the undried water-reducing agent from falling to the bottom of the box and condensing into agglomerates.

[0032] Furthermore, the spraying mechanism includes a rotating frame, a liquid phase nozzle and a gas phase nozzle. A rotating shaft is provided on the rotating frame, the rotating shaft is arranged horizontally, and the rotating frame is rotatably connected to the box body through the rotating shaft, so that the rotating frame can be connected to the box body through the pitch rotation of the rotating shaft; the gas phase nozzle and the liquid phase nozzle are both fixedly connected to one side of the rotating frame located in the box body, and the liquid phase nozzle and the gas phase nozzle are both arranged toward the inside of the box body.

[0033] It can be known that, through the setting of the rotating frame, the spraying mechanism can rotate relative to the box body, so as to facilitate the adjustment of the direction of the droplets sprayed by the liquid phase nozzle. When the rotating frame rotates relative to the box body and the rotating frame is arranged upwardly, the water reducer is sprayed in a certain direction, which increases the movement time of the water reducer in the box body, thereby increasing the evaporation amount of the water reducer, so that the water reducer is fully dried.

[0034] Preferably, the side of the rotating frame away from the rotating shaft is arranged in an arc shape coaxial with the rotating shaft, so that even when the rotating frame is rotating, the rotating frame and the box body are always in abutment and sealed to prevent leakage between the rotating frame and the box body.

[0035] Furthermore, the blowing mechanism also includes a positioning assembly, which includes a positioning plate and a locking piece. The positioning plate is fixedly connected to the outer wall of the box body, and a threaded hole is provided on the positioning plate. The locking piece is a screw, which is threadedly connected to the positioning plate, and one end of the screw abuts against the rotating frame to achieve positioning locking of the rotating frame.

[0036] As a preferred embodiment, the blowing mechanism further includes a positioning assembly, which includes a linear drive member, one end of which is hinged on the outer wall of the box body, and the other end of which is hinged on the rotating frame. The rotating frame is driven to rotate relative to the box body by the telescopic action of the linear drive mechanism. In this embodiment, the linear drive member is an electric push rod. In some other embodiments of the present application, the linear drive member can also be a hydraulic cylinder, a cylinder, or other components or structures that can achieve telescopic and positioning.

[0037] Further, the liquid phase nozzle is arranged inside the gas phase nozzle.

[0038] Specifically, the volume of the liquid phase nozzle is small, the volume of the gas phase nozzle is large, and the nozzle of the gas phase nozzle has a large accommodating space. The liquid phase nozzle is coaxially arranged in the middle of the gas phase nozzle outlet, so that the inner wall of the gas phase nozzle nozzle and the outer wall of the liquid phase nozzle nozzle form a ring-shaped air outlet area. The liquid phase nozzle sprays the concentrated water reducer into the box body to atomize the water reducer, and the gas phase nozzle blows out hot air from all around the water reducer, so that the hot air surrounds the sprayed water reducer droplets, which is conducive to the rapid dehydration and drying of the water reducer droplets.

[0039] Furthermore, a plurality of gas phase nozzles and a plurality of liquid phase nozzles are arranged, and the plurality of liquid phase nozzles are arranged in one-to-one correspondence with the plurality of gas phase nozzles.

[0040] It can be known that, by using multiple liquid phase nozzles and multiple gas phase nozzles, the injection amount of the water reducing agent and the intake amount of hot air are increased, thereby improving the production efficiency of the water reducing agent drying.

[0041] Furthermore, the bottom wall of the box body is arranged inclined.

[0042] It can be known that by arranging the bottom of the box at an angle, the dried water reducer powder slides along the inclined bottom of the box under the action of gravity, so that the dried water reducer powder is concentrated at a lower position at the bottom of the box, which is convenient for subsequent collection and transportation of the dried water reducer.

[0043] As a preferred embodiment, the bottom wall of the box is arranged to be inclined away from the blowing mechanism.

[0044] It can be known that arranging the bottom of the box body in an inclined direction away from the blowing mechanism is beneficial to the drying of the water reducer because the time for the water reducer to fall on the bottom wall of the box body is prolonged. In addition, by arranging the bottom wall in an inclined manner, it is convenient to collect the water reducer powder after drying.

[0045] Furthermore, the water reducing agent drying device also includes a vibration generating mechanism, and the vibration generating mechanism is installed at the bottom of the box body.

[0046] It can be known that the water reducer powder accumulates on the bottom wall of the box. When the inclination angle of the bottom wall of the box is small, the friction is large, and the water reducer powder is not easy to slide, so that the water reducer is not easy to slide to the lower side of the bottom of the box for collection. By arranging the vibration generating mechanism, the bottom wall of the box vibrates, and the dry water reducer powder accumulated on the bottom wall is constantly bounced and dropped due to the existence of vibration, which reduces the friction between the water reducer powder and the bottom wall of the box, so that the water reducer powder accumulated on the bottom wall of the box can slide smoothly along the bottom wall of the box to the lower side of the box for collection. It should be noted that in this embodiment, the vibration generating mechanism is a vibration motor. In some other embodiments, the vibration generating mechanism can also be a mechanism or component that can provide vibration.

[0047] Furthermore, the water reducing agent drying device also includes a conveyor, which is arranged in the box body, and the conveyor is arranged at one end of the bottom wall of the box body away from the blowing mechanism, and a discharge port is provided on the box body corresponding to the conveyor.

[0048] Specifically, the conveyor is a screw conveyor, which is arranged along the width direction of the box body. The settled water reducer powder slides along the bottom wall to the screw conveyor, and is transported to the discharge port by the screw conveyor and then discharged.

[0049] Furthermore, a baffle and a dust collector are arranged in the box. The baffle is fixedly connected to the top wall inside the box and extends downward. The dust collector is installed on the top wall of the inner wall of the box and is located on the side of the baffle away from the blowing mechanism.

[0050] Specifically, the dust collector is a bag dust removal mechanism, which is used for filtering to prevent the dried water reducer powder from being discharged from the exhaust mechanism, thereby reducing the loss of the water reducer and preventing the water reducer powder from polluting the air. The hot air ejected from the spraying mechanism is blocked by a baffle, so that a slow flow area is formed between the side of the baffle away from the spraying mechanism and the box body, and the dust collector is arranged in this slow flow area. The gas flow speed in the slow flow area is slow, which is conducive to the sedimentation of the dried water reducer powder and the filtering of the dried water reducer.

[0051] Furthermore, the top wall of the box body is arranged tilted, and the tilt direction of the top wall of the box body is opposite to the tilt direction of the bottom wall of the box body.

[0052] It can be known that when the spraying mechanism sprays obliquely upward, it is easy to touch the top wall of the box. By arranging the top wall of the box at an angle, the inclination direction of the top wall is made the same as the inclination direction of the spray sprayed by the spraying mechanism, thereby preventing the sprayed water reducer droplets from touching the top wall of the box and sticking to the top wall of the box.

[0053] The working principle of the utility model is as follows:

[0054] The air supply mechanism is turned on to provide hot air to the spray mechanism, and the hot air is sprayed from the gas phase nozzle of the spray mechanism into the box body. The vibration generating device is turned on to drive the bottom of the box body to vibrate. The liquid supply mechanism is turned on to provide concentrated water-reducing agent liquid to the spray mechanism, and the liquid supply mechanism sprays it through the liquid phase nozzle of the spray mechanism. The sprayed water-reducing agent droplets move in the box body, and the water in the water-reducing agent droplets evaporates continuously until it becomes water-reducing agent powder and settles on the bottom wall of the box body. Under the dual action of the vibration generating device and gravity, the water-reducing agent powder moves downward along the bottom wall and moves to the conveyor. The water-reducing agent powder is output from the discharge port on the box body through the conveyor. The exhaust gas passes through the dust collector and is discharged from the exhaust pipe. The dust collector filters the exhaust gas in the box body to prevent the water-reducing agent powder from being directly discharged from the exhaust pipe. If the water content of the water reducer is high and the horizontal arrangement of the spraying mechanism cannot completely dry the water reducer droplets, the relative position of the rotating frame and the box body is adjusted to rotate the rotating frame at a certain angle relative to the box body, so that the spraying mechanism is tilted upward to spray, thereby increasing the movement trajectory of the water reducer droplets in the box body, and then increasing the residence time of the water reducer droplets in the air inside the box body, so that the water reducer droplets are completely dried into powder.

[0055] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
