Description

Technical Field

[0001] This utility model relates to a fluidized bed cooling system, which is mainly used for cooling dry sand in V-process molding, regenerated sand in thermal regenerated sand, and dry sand in self-hardening sand molding. Background Technology

[0002] Fluidized bed utilizes airflow to fluidize sand, and incorporates a water-circulating heat exchanger. The sand boils and moves forward within the heat exchanger, carrying away some heat and thus lowering the sand temperature. Simultaneously, it removes fine powder from the sand. Currently, most fluidized bed systems have horizontally positioned fluidized chambers, leading to obstructed sand discharge and material flow. Furthermore, the fluidized plates are relatively thin and require welding with angle steel, making replacement difficult when worn. The lower air hood is also small, resulting in low suction efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned deficiencies in the existing technology and to provide a boiling cooling bed with a reasonable structural design.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: The boiling cooling bed includes a high-pressure blower, and its structural features are as follows: it also includes a chassis, a boiling chamber, a cooler, a sand blowing plate, a sand inlet, a sand outlet, and a suction hood. The high-pressure blower is connected to the chassis, the chassis is installed at the bottom of the boiling chamber, the sand blowing plate is installed between the boiling chamber and the chassis, the cooler is installed inside the boiling chamber and is located at the lower part of the boiling chamber, the upper part of the boiling chamber is a pressure reduction and diffusion zone, the suction hood is installed at the top of the boiling chamber, and the two ends of the boiling chamber are respectively provided with a sand inlet and a sand outlet.

[0005] Furthermore, the cooler is provided with an inlet and an outlet at both ends, the outlet is connected to the cooling tower, the cooling tower is connected to the circulating water tank, the circulating water tank is connected to the water pump, and the water pump is connected to the inlet.

[0006] Furthermore, it also includes a cylinder and a baffle, wherein the piston rod of the cylinder is connected to the baffle, and the baffle is located at the sand outlet.

[0007] Furthermore, the boiling tank is mounted on a support leg.

[0008] Furthermore, the boiling tank is tilted downwards from the sand inlet to the sand outlet.

[0009] Furthermore, the side wall of the boiling tank is provided with an observation window.

[0010] Furthermore, the tilt angle of the boiling tank is 3°-6°.

[0011] Furthermore, a boiling plate is bolted to the top of the sandblasting plate.

[0012] Compared with the prior art, this utility model has the following advantages: the boiling box in the boiling cooling bed is tilted, which makes the sand discharge and material flow smoother; at the same time, the boiling plate and the sand blowing plate are connected by bolts, and a thicker boiling plate can be selected to extend its service life and make it easy to replace when the boiling plate is damaged; the increased volume of the suction hood can increase the dust extraction space, which can make the pressure release faster and improve the suction efficiency.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0018] Example

[0019] See Figures 1 to 3 As shown in the accompanying drawings, the structures, proportions, sizes, etc., depicted in this specification are merely for illustrative purposes to aid those skilled in the art and to provide a clear understanding. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the use of terms such as "upper," "lower," "left," "right," "middle," and "one" in this specification is solely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0020] The boiling cooling bed in this embodiment includes a chassis 1, a high-pressure blower 2, a boiling box 3, a cooler 4, a sand blowing plate 6, a sand inlet 7, a sand outlet 8, a suction hood 9, a cylinder 10, and a baffle 11. The boiling box 3 is mounted on a support leg 14, and a boiling plate 16 is bolted to the top of the sand blowing plate 6.

[0021] In this embodiment, the high-pressure blower 2 is connected to the chassis 1, the chassis 1 is installed at the bottom of the boiling box 3, the sand blowing plate 6 is installed between the boiling box 3 and the chassis 1, the cooler 4 is installed inside the boiling box 3 and is located at the lower part of the boiling box 3, the upper part of the boiling box 3 is the pressure reduction and diffusion zone 5, the suction hood 9 is installed at the top of the boiling box 3, and the two ends of the boiling box 3 are respectively provided with sand inlet 7 and sand outlet 8.

[0022] In this embodiment, the cooler 4 is provided with an inlet 12 and an outlet 13 at both ends. The outlet 13 is connected to the cooling tower, the cooling tower is connected to the circulating water tank, the circulating water tank is connected to the water pump, and the water pump is connected to the inlet 12.

[0023] In this embodiment, the piston rod of the cylinder 10 is connected to the baffle 11, which is located at the sand outlet 8. The boiling tank 3 is tilted downwards from the sand inlet 7 to the sand outlet 8. The tilt angle of the boiling tank 3 is 3°-6°, and the side wall of the boiling tank 3 is provided with an observation window 15.

[0024] Specifically, this fluidized bed cooling system is mainly used for cooling dry sand in V-process molding, regenerated sand in thermal regenerated sand, and dry sand in self-hardening sand molding. It has significant effects and can remove dust from the sand.

[0025] The fluidized bed is divided into two layers. The lower layer is the chassis 1, which is connected to the high-pressure blower 2 through pipes. The upper layer is the fluidized box 3. The lower half of the fluidized box 3 is equipped with a cooler 4, which is made up of multiple sets of annular cooling water pipes. It is in full contact with air and sand particles. The upper half of the fluidized box 3 is the pressure reduction and diffusion zone 5. The chassis 1 is equipped with a sand blowing plate 6.

[0026] When hot sand enters the boiling chamber 3, the high-pressure air in the chassis 1 is sprayed upward through the nozzles on the sand blowing plate 6, causing the hot sand to boil and form a liquid-like flow state, which flows out from the sand outlet 8. At this time, the hot sand exchanges heat fully with the blown air and cooling water pipes. The cooling water flowing through the cooling water pipes carries away the heat in the hot sand, and the exhaust air also directly carries away some of the heat and fine powder contained in the sand, forming a dual cooling effect of air and cooling water on the hot sand.

[0027] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model.
