Description

Technical Field

[0001] This utility model relates to the field of casting equipment technology, specifically a sand treatment air-cooling and water-cooling device. Background Technology

[0002] In the lost foam casting process, quartz sand, as the core molding material, needs to be recycled. The temperature of the recycled quartz sand after the casting is unpacked often reaches over 80℃. If used directly in subsequent packing processes, it will not only damage the foam model, leading to casting failure, but also pose a safety hazard of burns to workers caused by the high-temperature sand particles. Simultaneously, the falling and flowing sand particles generate a large amount of dust. If not handled promptly, this pollutes the working environment and harms the respiratory health of workers. Some equipment uses fluidized bed cooling, relying on high-speed airflow to suspend and transfer heat from the sand particles. However, this method is only suitable for coarse-grained ordinary molding sand and cannot handle high-density, fine-grained quartz sand. The sand particles are prone to suspending, leading to cooling failure. Furthermore, the cooling water pipes are directly exposed to the high-speed fluidized sand particles, resulting in severe wear and requiring frequent maintenance and replacement.

[0003] The existing publicly available technical solution CN203541430U discloses an inclined-blowing fluidized bed for rapid cooling, which solves the problems of high manufacturing cost and poor cooling effect of hot sand cooling equipment in foundries. Its features include: a circulating water cooling device installed inside the fluidized bed; a dust collection hood with a dust exhaust chimney above; and a wind box at the bottom. A bed plate with capped inclined nozzles is installed between the fluidized bed and the wind box. The air inlet pipe of the wind box is connected to the air supply pipe connected to the air outlet of the blower through an air inlet valve. It has advantages such as reasonable structure and simple operation, with a production rate of up to 15T / h and the sand outlet temperature can be reduced to below 45℃, fully meeting the continuous operation needs of foundries and having broad application value.

[0004] However, the existing technical solutions still have some shortcomings in actual implementation. The device achieves heat exchange by suspending sand particles through high-speed airflow, but the cooling water pipes are directly exposed to the high-speed fluidized sand flow. The sand particles will form a continuous high-frequency scouring and micro-cutting effect on the pipe wall, resulting in thinning of the pipe wall, honeycomb wear, and even perforation and leakage. Frequent shutdowns for disassembly and replacement are required, which not only increases maintenance costs but also seriously affects the continuity of production. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the existing technology uses high-speed airflow to suspend sand particles for heat exchange, but the cooling water pipes are directly exposed to the high-speed fluidized sand flow, the sand particles will continuously and frequently scour and micro-cut the pipe wall, resulting in thinning of the pipe wall, honeycomb wear, and even perforation and leakage. Frequent shutdowns for disassembly and replacement are required, which not only increases maintenance costs but also seriously affects the continuity of production.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0009] The water-cooling assembly includes a housing; a water inlet tank welded to the front end of the housing; and a cooling pipe disposed in the center of the housing.

[0010] The air-cooled assembly includes an air-cooled air pump fixed to the middle of the lower end of the housing by external bolts; and a first air-cooled box installed inside the lower end face of the housing.

[0011] The dust removal assembly includes a dust removal air pump fixed to the left side of the housing by external bolts; and a second dust removal pipe connected to the rear end of the dust removal air pump.

[0012] As a further embodiment of this utility model: the water-cooling assembly also includes thermally conductive silicone and wear-resistant tiles; the thermally conductive silicone is disposed on the inner wall of the housing and fills the gap between the housing and the cooling pipe; the wear-resistant tiles are installed on the front surface of the cooling pipe.

[0013] As a further embodiment of this utility model: the water cooling assembly also includes support legs and a return water tank; the support legs are welded to the four lower corners of the housing; the return water tank is welded to the rear end of the housing; and the front and rear ends of the cooling pipe are connected to the interior of the inlet tank and the return water tank.

[0014] As a further improvement of this utility model: the air-cooling component further includes an air-cooling pipe and an air outlet; the air-cooling pipe is connected to the output end of the air-cooling pump; the air outlet is located on the upper surface of the first air-cooling box.

[0015] As a further embodiment of this utility model: the air-cooling assembly further includes a second air-cooling box and a limiting block; the second air-cooling box is disposed at the upper front of the first air-cooling box, and the lower end of the second air-cooling box is connected through to the first air-cooling box; the limiting block is fixed at the rear of the first air-cooling box.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model, by installing stainless steel anti-wear tiles on the front of the cooling pipe surface, can directly resist the scouring and cutting of the falling quartz sand, avoid water leakage failure caused by wear of the cooling pipe, and extend the service life of the equipment. At the same time, the thermally conductive silicone filling the gap between the box and the cooling pipe can fill the micro gaps and reduce the contact thermal resistance. Combined with the water circulation of the inlet and return water tanks, it ensures efficient heat transfer between the cooling water and the quartz sand, solving the contradiction of easy wear and low thermal conductivity of the existing equipment cooling pipes.

[0021] 2. In this invention, cold air delivered by an air-cooled pump enters the first air-cooled box through an air-cooled pipe and is evenly blown out through the air outlet on the upper surface and the through second air-cooled box.

The limiting block at the rear of the first air-cooled box can limit the sand particle conveying range, eliminating the need for additional conveying equipment. This is suitable for the short-process requirements from the elevator to the collection hopper, reducing energy consumption and equipment complexity.

After being transported to the collector through the first dust removal pipe, the air is then introduced into the dust removal filter box through the third dust removal pipe for filtration. This effectively avoids dust pollution during the quartz sand processing, protects the working environment and personnel health, and solves the defect of existing equipment lacking integrated dust removal function.

Detailed Implementation

[0029] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0032] Example 1:

[0033] Please see Figures 1-5 This is the first embodiment of the present invention.

[0034] This embodiment provides a sand processing air-cooling and water-cooling device, including a water-cooling component 1; an air-cooling component 2 for air-cooling and cooling quartz sand; and a dust removal component 3 for treating dusty air.

[0035] The water-cooled assembly 1 includes a housing 101; a water inlet tank 102 welded to the front end of the housing 101; and a cooling pipe 105 disposed in the center of the housing 101.

[0036] The air-cooled assembly 2 includes an air-cooled air pump 201 fixed to the middle of the lower end of the housing 101 by external bolts; and a first air-cooled box 203 installed inside the lower end face of the housing 101.

[0037] The dust removal assembly 3 includes a dust removal air pump 304 fixed to the left side of the housing 101 by external bolts; and a second dust removal pipe 306 connected to the rear end of the dust removal air pump 304.

[0038] Specifically, the water-cooling assembly 1 also includes thermally conductive silicone 106 and anti-wear tiles 107; the thermally conductive silicone 106 is disposed on the inner wall of the housing 101 and fills the gap between the housing 101 and the cooling pipe 105; the anti-wear tiles 107 are installed on the front surface of the cooling pipe 105.

[0039] Furthermore, the thermally conductive silicone 106 filling the gap between the housing 101 and the cooling pipe 105 is fully filled, and the wear-resistant tile 107 is made of stainless steel, which has both good wear resistance and thermal conductivity.

[0040] Specifically, the water-cooling assembly 1 also includes support legs 104 and a return water tank 103; the support legs 104 are welded to the four lower corners of the housing 101; the return water tank 103 is welded to the rear end of the housing 101, and the front and rear ends of the cooling pipe 105 are connected to the interior of the inlet tank 102 and the return water tank 103.

[0041] Furthermore, the cooling water after heat exchange flows into the return water tank 103, where it can be recycled or discharged as needed.

[0042] Specifically, the air-cooled assembly 2 also includes an air-cooled pipe 202 and an air outlet 204; the air-cooled pipe 202 is connected to the output end of the air-cooled pump 201; the air outlet 204 is opened on the upper surface of the first air-cooled box 203.

[0043] Furthermore, the diameter of the air outlet 204 is smaller than that of the quartz sand. The cold air enters the first air-cooled box 203 through the air-cooling pipe 202, and is then blown out evenly through the air outlet 204 on the upper surface of the first air-cooled box 203 and the second air-cooled box 205 that is connected to it.

[0044] During use, the device is stably supported on the ground by the legs 104 of the water-cooling component 1. Before starting, it is necessary to ensure that the water inlet tank 102, the water return tank 103 and the cooling pipe 105 are connected and sealed, and that the thermally conductive silicone 106 between the housing 101 and the cooling pipe 105 is fully filled. After starting the water-cooling system, cooling water enters the cooling pipe 105 from the water inlet tank 102. Several sets of cooling pipes 105 are arranged in a staggered manner in the middle position inside the housing 101 to increase the contact area with the quartz sand. When the quartz sand is fed into the feed port at the top of the housing 101, the quartz sand directly contacts the wear-resistant tile 107 on the surface of the cooling tube 105. The wear-resistant tile 107 is made of stainless steel and has good wear resistance and thermal conductivity. It can resist the erosion of sand particles to protect the cooling tube 105, and will not hinder the heat exchange between the cooling water and the quartz sand in the cooling tube 105. The cooled water after heat exchange flows into the return water tank 103, which can be recycled or discharged as needed. At this time, the first cooling of the quartz sand is completed. The water-cooled quartz sand falls to the bottom of the housing 101, and some of the heat is transferred to the inner wall of the housing 101. Then, it is efficiently conducted to the cooling tube 105 through the thermally conductive silicone 106 for secondary heat exchange, further enhancing the heat dissipation effect of the quartz sand. Then, the air-cooling pump 201 of the air-cooling component 2 is activated. Cold air enters the first air-cooling box 203 through the air-cooling pipe 202, and is then evenly blown out through the air outlet 204 on the upper surface of the first air-cooling box 203 and the second air-cooling box 205 that is connected to it, thus performing a second cooling of the sand particles and generating directional thrust. The triangular limiting block 206 can effectively block the sand particles, preventing them from being pushed by the airflow to an area outside the discharge port. Finally, the cooled sand particles enter the next process from the discharge port.

[0045] In summary, this utility model, by installing stainless steel anti-wear tiles 107 at the front of the cooling pipe 105, can directly resist the scouring and cutting of falling quartz sand, avoid water leakage failure of the cooling pipe 105 due to wear, and extend the service life of the equipment. At the same time, the thermally conductive silicone 106 filling the gap between the housing 101 and the cooling pipe 105 can fill the micro gaps and reduce the contact thermal resistance. Combined with the water circulation of the inlet tank 102 and the return tank 103, it ensures efficient heat transfer between the cooling water and the quartz sand, solving the contradiction of easy wear and low thermal conductivity of the existing equipment cooling pipes. This invention uses a wind-cooled air pump 201 to deliver cold air, which enters the first air-cooled box 203 through the air-cooled pipe 202. The air is then blown out evenly through the air outlet 204 on the upper surface and the through second air-cooled box 205. This not only cools the water-cooled pre-cooled quartz sand a second time, but also generates directional thrust to move the sand particles. No additional conveying equipment is required, which is suitable for the short process from the elevator to the collection hopper, reducing energy consumption and equipment complexity.

[0046] Example 2:

[0047] Please see Figures 1-5 This is the second embodiment of the present utility model.

[0048] Specifically, the air-cooled assembly 2 also includes a second air-cooled box 205 and a limiting block 206; the second air-cooled box 205 is located at the upper front of the first air-cooled box 203, and the lower end of the second air-cooled box 205 is connected through to the first air-cooled box 203; the limiting block 206 is fixed to the rear of the first air-cooled box 203.

[0049] Furthermore, cold air enters the first air-cooled box 203 through the air-cooling pipe 202, and is then evenly blown out through the air outlet 204 on the upper surface of the first air-cooled box 203 and the second air-cooled box 205 that is connected to it, thus providing a second cooling effect on the sand particles and generating directional thrust. The triangular limiting block 206 can effectively block the sand particles, preventing them from being pushed out of the discharge port by the airflow.

[0050] Specifically, the dust removal assembly 3 also includes a dust removal filter box 305 and a third dust removal pipe 307; the dust removal filter box 305 is connected to the end of the second dust removal pipe 306; and the third dust removal pipe 307 is connected to the upper end of the dust removal filter box 305.

[0051] Furthermore, the dust collector filter box 305 has several filter plates that can be detachably installed inside.

[0052] Specifically, the dust removal assembly 3 also includes a collector 303 and a first dust removal pipe 302; the collector 303 is connected to the end of the third dust removal pipe 307; the first dust removal pipe 302 is connected to the front and rear ends of the collector 303.

[0053] Furthermore, the dust-laden air enters the collector 303 through the first dust removal pipe 302, and then enters the dust removal filter box 305 for filtration through the third dust removal pipe 307.

[0054] Specifically, the dust removal assembly 3 also includes a dust removal hood 301; the dust removal hood 301 is connected to the end of the first dust removal pipe 302, and the lower end of the dust removal hood 301 is connected to the housing 101.

[0055] Furthermore, the dust collector hood 301 has a large bottom area, which can expand the collection range to attract more dust-laden air. The dust-laden air generated during operation is efficiently collected by the dust collector hood 301.

[0056] When in use, the dust removal air pump 304 of the dust removal component 3 is started. The bottom area of ​​the dust removal hood 301 is large, which can expand the collection range to attract more dust-laden air. The dust-laden air generated during the operation is efficiently collected by the dust removal hood 301, and transported to the collector 303 through the first dust removal pipe 302. Then, it enters the dust removal filter box 305 through the third dust removal pipe 307 for filtration and purification, so as to achieve efficient separation of dust.

[0057] In summary, this utility model, by utilizing the large bottom area of ​​the dust collector hood 301, can expand the dust-laden air collection range. After being transported to the collector 303 via the first dust collector pipe 302, the dust is then introduced into the dust collector filter box 305 via the third dust collector pipe 307 for filtration. This effectively avoids dust pollution during the quartz sand processing, protects the working environment and personnel health, and solves the defect of existing equipment lacking integrated dust removal functions.
