Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, and in particular to a casting desanding device. Background Technology

[0002] Castings are products made using casting technology. In casting, molten metal is poured into a mold, which is usually made of molding sand. Therefore, after the casting is removed from the mold, its surface is often covered with molding sand, requiring the use of a sand removal device to remove the sand from the surface of the casting.

[0003] A search revealed a novel casting sand removal device in patent application number 202022533510.9. This device uses a first motor to drive a rotating table to rotate, which in turn drives the casting to rotate. A spraying mechanism removes sand from the casting from all sides, improving the sand removal effect. A vibrator further vibrates the casting, increasing the sand removal rate. A second motor drives a high-pressure nozzle to move up and down, thereby comprehensively removing sand from the casting and improving the sand removal effect.

[0004] However, after the above-mentioned device removes sand from the surface of the casting, water or a small amount of molding sand often remains on the surface of the casting. However, the above-mentioned device lacks a structure for cleaning the casting after sand removal. Therefore, not only will the sand removal on the surface of the casting be incomplete, affecting the sand removal effect of the casting, but the casting will also be damp, making it inconvenient to store the casting. This will result in a long drying time for the casting, affecting the subsequent production and processing of the casting. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1-9 As shown, a casting desanding device includes a housing 1 and a desanding box 2 installed on the top of the housing 1. The desanding box 2 is equipped with a clamping component for holding the casting, and a door is hinged to the front side of the desanding box 2. The desanding box 2 is also equipped with a high-pressure water spray component for desanding the casting. The high-pressure water spray component includes a distribution plate 19 installed on the inner wall of the desanding box 2. The distribution plate 19 has a water spraying chamber 23, and a high-pressure water nozzle 25 is installed on one side of the distribution plate 19 to spray water toward the casting. A controller (not shown in the figure) can be installed on the side wall of the housing 1 to facilitate the operation of various electrical components in the device, and the controller can be a PLC controller.

[0031] It also includes a purging assembly for cleaning the casting. The purging assembly includes an air jet chamber 24 opened inside the distribution plate 19 and a pulse air manifold 4 fixed on the top of the desanding box 2. One end of the pulse air manifold 4 is connected to an air supply pipe 5 that communicates with the air jet chamber 24, and a pulse solenoid valve 6 is installed on the air supply pipe 5. An air jet nozzle 26 that sprays air toward the casting is also installed on one side of the distribution plate 19, and the air jet nozzle 26 communicates with the air jet chamber 24.

[0032] Specifically, regarding the aforementioned clamping components, such as Figures 4-6 As shown, the clamping device includes a placement platform 13 and a pressure plate 12 located directly above the placement platform 13. In addition to the top of the sand box 2, a cylinder 3 is also installed, and the telescopic end of the cylinder 3 is rotatably connected to the top of the pressure plate 12.

[0033] Furthermore, in order to spray water onto the castings, a water pump 9 is provided on one side of the housing 1, and a water pump 10 is connected between one end of the water pump 9 and the housing 1, and a water supply pipe 7 is connected to the other end of the water pump 9 and communicates with the water spraying chamber 23. The water pump 10 is connected to the water storage chamber 20, and a liquid filling valve is provided on the front side of the housing 1 to facilitate adding water into the water storage chamber 20.

[0034] In this embodiment, to facilitate all-around sand removal from the casting, such as Figures 4-6 As shown, a motor 15 is installed in the mounting cavity 22, and a main gear 16 is installed on the main shaft of the motor 15. A shaft is installed at the bottom end of the placement platform 13, and the bottom end of the shaft extends into the mounting cavity 22 and is fitted with a secondary gear 17 that meshes with the main gear 16.

[0035] As described above, when desanding the casting, the front door of the desanding box 2 is opened first, and the casting is placed on the placement platform 13. The pressure plate 12 is driven down by the cylinder 3 so that the pressure plate 12 presses against the top of the casting to clamp and fix the casting. Then the box door is closed, and the water in the water storage chamber 20 is pumped out by the water pump 9 and the water pumping pipe 10 and transported into the water spraying chamber 23 through the water delivery pipe 7. Then the water is sprayed onto the casting through the high-pressure water nozzle 25 to remove sand from the surface of the casting.

[0036] Furthermore, during the desanding process, the main gear 16 can be driven to rotate by the motor 15. Subsequently, the main gear 16 drives the placement platform 13 to rotate through the meshing secondary gear 17, thereby causing the placement platform 13 to rotate the casting and thus achieving all-round washing of the casting, thereby improving the desanding effect of the casting.

[0037] Simultaneously, after sand removal is completed, the water pump 9 is stopped, causing the high-pressure water nozzle 25 to stop spraying water. Then, the pulse solenoid valve 6 is controlled to operate, causing the pulse air manifold 4 to intermittently deliver compressed gas to the jet chamber 24 through the air delivery pipe 5. The compressed gas is then sprayed onto the casting through the jet nozzle 26 to blow away residual water or sand on the surface of the casting, thereby improving the sand removal effect on the surface of the casting and enabling the surface of the casting to dry quickly after sand removal, which is beneficial to improving the drying efficiency of the casting and facilitating the storage of the casting.

[0038] Additionally, in this embodiment, as Figure 1 , Figure 2 as well as Figures 4-8 As shown, a drain hole is provided on one side of the bottom of the sand removal box 2. A bracket 14 is installed inside the casing 1, and the bracket 14 divides the inside of the casing 1 into a recovery chamber 21, a water storage chamber 20 and an installation chamber 22. The drain hole connects the inside of the sand removal box 2 with the recovery chamber 21. A filter assembly 11 is also provided on the casing 1 to filter the water discharged from the drain hole.

[0039] Specifically, the filter assembly 11 includes a mounting bracket 111 inserted into the recovery chamber 21. The mounting bracket 111 has a first filter screen 113, a second filter screen 114 and a third filter screen 115 inserted into it from top to bottom. The chassis 1 has a through slot for inserting and removing the mounting bracket 111. One end of the mounting bracket 111 is also equipped with a cover plate 112 to seal the through slot.

[0040] Furthermore, to facilitate waste discharge from the recovery chamber 21, such as... Figure 2 , Figure 5 and Figure 6 As shown, a waste discharge valve is connected to the side of the casing 1 away from the water pump 9. A guide plate 18 is provided at the bottom of the inside of the recovery chamber 21, and the top of the guide plate 18 is obliquely cut to form a guide platform that is inclined towards the inlet of the waste discharge valve.

[0041] As described above, during the sand removal process, the wastewater accumulated in the sand removal box 2 can be discharged into the recovery chamber 21 through the drain hole. At this time, the wastewater can pass through the first filter screen 113, the second filter screen 114 and the third filter screen 115 in the mounting frame 111 in sequence to achieve multi-stage filtration. After filtration, the water is stored in the recovery chamber 21, and then the water in the recovery chamber 21 can be discharged through the waste discharge valve to facilitate the subsequent water collection in the recovery chamber 21. This achieves the filtration treatment of wastewater, which is conducive to the recycling of wastewater, greatly improves the utilization rate of water resources, avoids the waste of water resources, and helps to reduce the water cost during casting sand removal, and facilitates the sand removal process of castings.

[0042] Secondly, in this embodiment, in order to achieve the recycling of water resources, such as Figures 1-6 As shown, a three-way valve is also installed on the pumping pipe 10, and one end of the three-way valve is connected to the pumping branch pipe 8, which is connected to the recovery chamber 21.

[0043] During sand removal, the inlet pipe of water pump 9 can be switched by a three-way valve, that is, the pumping branch pipe 8 is connected to the inlet end of water pump 9. Then, water pump 9 extracts the filtered water in the recovery chamber 21 through the pumping branch pipe 8 and sends it into the spray chamber 23 through the water supply pipe 7 for high-pressure spray nozzle 25 to spray out, thereby further realizing the recycling of water resources, avoiding the waste of water resources, and greatly reducing the sand removal cost of castings.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
