Description

Technical Field

[0001] This utility model relates to the field of casting sand cooling technology, and in particular to a fluidized bed cooling system for casting sand. Background Technology

[0002] Sand plays a vital role in construction, metallurgy, and road building. Although the level of automation in mechanized production is constantly improving, and production efficiency is increasing, cost savings still require attention to efficiency. For example, after being separated from the casting billet, foundry sand needs to undergo crushing, screening, and cooling processes before being sent back to the previous forming process. Since the hot sand after casting is at a very high temperature, how to quickly cool it for reuse is key to improving casting efficiency.

[0003] Chinese patent application number CN202322278010.9, entitled "A Boiling Cooling Bed," includes a bed body with a perforated boiling plate horizontally arranged inside. The boiling plate divides the bed body into a boiling chamber and a blowing chamber from top to bottom. A feed inlet is located at the top of the bed body, and a gap is left between the end of the boiling plate away from the feed inlet and the interior of the bed body, forming a discharge outlet. A blower is located on one side of the bed body, connected to the blowing chamber via a ventilation duct. A dust suction port is located at the top of the bed body near the discharge outlet, connected to an exhaust fan. A water circulation cooling mechanism is installed on the bed body to cool the hot sand. However, during use, the foundry sand enters the bed body through the feed inlet and is always in contact with the cooling water pipe below the feed inlet. This causes the temperature of the cooling water pipe at this location to be higher than in other locations, resulting in poor cooling effect. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a fluidized bed for casting sand, which solves the problem of poor cooling effect.

[0005] To achieve the above objectives, a fluidized bed for casting sand is provided, comprising a bed body, an opening on the upper side of the bed body, and sliding grooves on both the front and rear sides. A moving mechanism is provided in the sliding grooves, and a cooling water pipe and a fluidized bed plate are fixedly connected in the bed body located below the moving mechanism.

[0006] The moving mechanism includes a threaded rod and a sliding rod. The threaded rod is located in a front sliding groove, and the sliding rod is located in a rear sliding groove. Both the threaded rod and the sliding rod are equipped with sliders. The sliders are slidably connected to the sliding rod and threadedly connected to the threaded rod. A container is fixedly connected between the sliders on both sides. A drive motor is fixedly connected to the right side of the bed.

The partition has a second through hole and is slidably connected to the container.

[0007] According to the aforementioned fluidized bed for casting sand, an inlet water pipe and an outlet water pipe are fixedly connected to the bed body located on both sides of the cooling water pipe. There are several cooling water pipes arranged in a row, and both ends of the cooling water pipes are connected to the inlet water pipe and the outlet water pipe, respectively.

[0008] According to the aforementioned fluidized bed cooling bed for foundry sand, a water tank is provided on the lower side of the bed body, a water pump is provided in the water tank, and a water pipe is fixedly connected to the upper side. There are two water pipes, which are respectively fixedly connected to an inlet water pipe and an outlet water pipe. The other end of the water pipe connected to the inlet water pipe is fixedly connected to the water pump.

[0009] According to the aforementioned fluidized bed cooling bed for casting sand, the fluidized bed plate is located below the cooling water pipe and is inclined. A motor is fixedly connected to the inner side of the bed body located at the lower end of the fluidized bed plate, and a hammer is fixedly connected to the output end of the motor.

[0010] According to the aforementioned fluidized bed cooling bed for foundry sand, a guide plate is fixedly connected to the right side of the bed body, and the inner end of the guide plate is located below the fluidized bed.

[0011] According to the aforementioned fluidized bed cooling bed for foundry sand, an air inlet is provided on the front side of the bed body, and the air inlet can be connected to an external blower.

[0012] According to the aforementioned fluidized bed cooling bed for foundry sand, a discharge pipe and support legs are fixedly connected to the lower side of the bed body, and there are four support legs that are evenly distributed.

[0013] According to the aforementioned fluidized bed cooling system for casting sand, a cover plate is provided inside the opening.

[0014] This utility model has the following beneficial effects:

[0015] Compared with existing technologies, by providing a moving mechanism on the bed, hot sand is placed into the holding box through the opening during use. The drive motor is started and the partition is pulled so that the second through hole on the partition coincides with the first through hole. The drive motor drives the holding box to move back and forth in the slide groove through the threaded rod and the slider. At this time, as the holding box moves back and forth, the hot sand falls evenly from the box onto the cooling water pipe, so that the wall of the cooling water pipe can better contact the hot sand and exchange heat, thereby improving the cooling effect.

A discharge pipe and four support legs 13 are fixedly connected to the lower side of the bed body 1. During the cooling of hot sand, some hot sand will fall from the fluidized plate 8 into the bed body 1. After the cooling is completed, the discharge pipe at the bottom of the bed body 1 can be opened to remove the sand.

[0027] The bed body 1 has an opening 2 on the upper side and sliding grooves 3 on both the front and rear sides. A cover plate 21 is provided in the opening 2. The cover plate 21 is connected to the opening 2 by a hinge. When maintaining the bed body 1, the cover plate 21 can be flipped open directly. A moving mechanism 4 is provided in the sliding groove 3. A cooling water pipe 5 and a boiling plate 8 are fixedly connected in the bed body 1 located below the moving mechanism 4. The boiling plate 8 is located below the cooling water pipe 5 and is inclined to facilitate the discharge of hot sand. A motor 9 is fixedly connected in the inner side of the bed body 1 located below the boiling plate 8. A hammer 91 is fixedly connected to the output end of the motor 9. Under the action of the hammer 91, hot sand is prevented from remaining on the boiling plate 8. A guide plate 10 is fixedly connected to the right side of the bed body 1. The inner end of the guide plate 10 is located below the boiling plate 8.

[0028] The bed body 1 located on both sides of the cooling water pipe 5 is fixedly connected to the inlet water pipe 6 and the outlet water pipe 7 respectively. There are several cooling water pipes 5, which are arranged in a row. The two ends of the cooling water pipe 5 are connected to the inlet water pipe 6 and the outlet water pipe 7 respectively. During the hot sand cooling process, the hot sand falls evenly from the holding box 44 onto the cooling water pipe 5 and exchanges heat after contacting the pipe wall of the cooling water pipe 5. A water tank 11 is provided on the lower side of the bed body 1. A water pump is provided in the water tank 11, and a water pipe 12 is fixedly connected to the upper side. There are two water pipes 12, which are fixedly connected to the inlet water pipe 6 and the outlet water pipe 7 respectively. The other end of the water pipe 12 connected to the inlet water pipe 6 is fixedly connected to the water pump. Under the action of the water tank 11, the inlet water pipe 6, the outlet water pipe 7, the cooling water pipe 5 and the water pump, a circulating cooling system is formed. This circulating cooling system is the same as that in the prior art, so its principle will not be described in this patent.

[0029] The moving mechanism 4 includes a threaded rod 41 and a sliding rod 42. The threaded rod 41 is located in the front sliding groove 3, and the sliding rod 42 is located in the rear sliding groove 3. Both the threaded rod 41 and the sliding rod 42 are provided with sliders 43. The sliders 43 are slidably connected to the sliding rod 42 and threadedly connected to the threaded rod 41. A container 44 is fixedly connected between the two sliders 43. A drive motor 46 is fixedly connected to the right side of the bed 1. The output end of the drive motor 46 is fixedly connected to the threaded rod 41. The container 44 is provided with a first through hole 441. The slider 43 is located at the front... A partition 45 is slidably connected to the side. The partition 45 has a second through hole 451 and is slidably connected to a container 44. During operation, hot sand is put into the container 44 through the opening 2. At this time, the drive motor 46 is started and the partition 45 is pulled so that the second through hole 451 on the partition 45 coincides with the first through hole 441. The drive motor 46 drives the container 44 to move back and forth in the slide groove 3 through the threaded rod 41 and the slider 43, so that the hot sand falls evenly from the container 44 onto the cooling water pipe 5 and is cooled.

[0030] Working principle: When in use, start the water pump and blower. The water pump delivers water from the water pipe 12 to the cooling water pipe 5, and then from the water outlet pipe 7 into the water tank 11 to form a cold circulation.

[0031] Then, the hot sand is placed into the container 44 through the opening 2. At this time, the drive motor 46 is started and the partition 45 is pulled so that the second through hole 451 on the partition 45 coincides with the first through hole 441. The drive motor 46 drives the container 44 to move back and forth in the slide groove 3 through the threaded rod 41 and the slider 43. At this time, the hot sand falls evenly from the container 44 onto the cooling water pipe 5 and exchanges heat after contacting the pipe wall of the cooling water pipe 5. At this time, under the action of the motor 9, the hammer 91 is driven to strike the boiling plate 8, so that the hot sand on the plate slides down to the guide plate 10 and flows out.
