Description

Technical Field

[0001] This utility model relates to the field of sand mixer technology, and in particular to a water adding device for a sand mixer. Background Technology

[0002] A sand mixer is a widely used piece of equipment in the foundry industry, primarily used to mix materials such as sand, binder, and water to prepare molding sand for casting molds. During the sand mixing process, clay (bentonite) acts as the binder for the molding sand, and its performance depends on thorough mixing with water. Clay has no binding properties in its dry state; only after mixing with water to form a clay paste can it coat the surface of the sand particles, creating bonds between them and thus giving the molding sand a certain strength and stability. Therefore, adding water is a crucial step in ensuring the uniform dispersion of clay and enabling it to exert its binding effect.

[0003] In existing technologies, most sand mixers use fixed nozzles or one-way water pipes to directly inject water, which causes the water distribution to be concentrated in local areas. This results in insufficient or excessive water being added to the edge areas, requiring repeated stirring to achieve the required mixing, which seriously affects the sand mixing efficiency. Therefore, we propose a water adding device for sand mixers to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a water addition device for a sand mixer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A water supply device for a sand mixer includes a sand mixer body and a dual-chamber water tank. An electric push rod is fixedly connected inside the dual-chamber water tank. A rectangular metal plate is fixedly connected to the top of the output end of the electric push rod. A rectangular rubber piston is fixedly connected to the top of the rectangular metal plate. A water outlet rubber hose is fixedly connected to the top of the dual-chamber water tank. A platform is placed on top of the sand mixer body. An equipment frame is fixedly connected to the top of the platform. A through hole is opened on the outer wall of the platform. A vertical pipe is rotatably connected to the inner wall of the through hole. A spray pipe is fixedly connected to the bottom of the vertical pipe. Two nozzles are fixedly connected to the outer wall of the spray pipe. A transmission assembly is provided inside the equipment frame.

[0007] Preferably, the transmission assembly includes an electric motor, the inner wall of the equipment frame is fixedly connected to the outer wall of the electric motor, and gears are fixedly sleeved on both the output shaft of the electric motor and the outer wall of the vertical tube. The two gears are meshed and connected, and the transmission assembly drives the vertical tube to rotate.

[0008] Preferably, the inner wall of the dual-chamber water tank is provided with a sliding hole, and the inner wall of the sliding hole is slidably connected to the outer wall of the output end of the electric push rod, so that the rectangular metal plate can be moved up and down by setting the electric push rod.

[0009] Preferably, the inner wall of the dual-chamber water tank is slidably connected to the outer wall of the rectangular rubber piston and the rectangular metal plate, and the rectangular rubber piston increases the sealing performance.

[0010] Preferably, the top of the dual-chamber water tank is fixedly connected to an addition pipe, and the inner wall of the addition pipe is threaded with a plug to seal the addition pipe.

[0011] Preferably, a rotary joint is fixedly connected to the top of the vertical pipe, and one end of the water outlet rubber hose penetrates the outer wall of the equipment frame and is fixedly connected to the top of the rotary joint.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution uses an electric push rod driven piston-type water supply mechanism, combined with a rotary spraying device, to achieve a uniform and stable water supply effect. The rotary joint and gear transmission mechanism enable the nozzle to rotate in all directions during the spraying process, forming a uniformly covered fan-shaped water curtain, effectively solving the problem of uneven water supply in traditional fixed nozzles. Furthermore, the access plate can be removed from the top of the sand mixer body after water supply is completed, without affecting the use of the sand mixer body. Attached Figure Description

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figures 1-3 As shown, a water supply device for a sand mixer is disclosed, comprising a sand mixer body 1 (S1116) and a double-chamber water tank 2. The sand mixer body 1 (S1116) is welded from wear-resistant steel plate, and the inner wall is lined with replaceable wear-resistant lining plate. A sand discharge gate is provided on the right side. The double-chamber water tank 2 is a split stainless steel structure with a partition in the middle to form a double chamber. An electric push rod 3 is fixedly connected inside the double-chamber water tank 2. The electric push rod 3 controls the stroke of a rectangular rubber piston 5 to achieve quantitative water supply. A sliding hole is provided on the inner wall of the double-chamber water tank 2, and the inner wall of the sliding hole is slidably connected to the outer wall of the output end of the electric push rod 3.

[0021] A rectangular metal plate 4 is fixedly connected to the top of the output end of the electric push rod 3. A rectangular rubber piston 5 is fixedly connected to the top of the rectangular metal plate 4. The edge of the rectangular rubber piston 5 is provided with a double-layer sealing lip. The inner wall of the dual-chamber water tank 2 is slidably connected to the outer wall of the rectangular rubber piston 5 and the rectangular metal plate 4.

[0022] The top of the dual-chamber water tank 2 is fixedly connected to an addition pipe 7. The inner wall of the addition pipe 7 is threaded with a plug 6. The plug 6 facilitates quick water addition and maintenance of the interior of the dual-chamber water tank 2. The top of the dual-chamber water tank 2 is fixedly connected to an outlet rubber hose 8. The outlet rubber hose 8 is embedded with a stainless steel spiral support to ensure smooth water flow and prevent bending and blockage.

[0023] A ramp 9 is placed on top of the sand mixer body 1 (S1116). The contact surface between the ramp 9 and the sand mixer body 1 (S1116) is provided with anti-slip texture. An equipment frame 10 is fixedly connected to the top of the ramp 9. A through hole is opened on the outer wall of the ramp 9. A vertical pipe 11 is rotatably connected to the inner wall of the through hole. A bearing is fixedly sleeved on the outer wall of the vertical pipe 11. The outer ring of the bearing is fixedly connected to the top of the ramp 9. The bearing assists the vertical pipe 11 to rotate stably. A spray pipe 12 is fixedly connected to the bottom of the vertical pipe 11. Two nozzles 13 are fixedly connected to the outer wall of the spray pipe 12. The spray range of the nozzles 13 is fan-shaped.

[0024] The equipment frame 10 is equipped with a transmission assembly, which includes an electric motor 14. The electric motor 14 is powered by an external power source through existing wires. The inner wall of the equipment frame 10 is fixedly connected to the outer wall of the electric motor 14. Gears 15 are fixedly fitted on both the output shaft of the electric motor 14 and the outer wall of the vertical pipe 11. The two gears 15 are meshed together. A rotary joint 16 is fixedly connected to the top of the vertical pipe 11. One end of the water outlet rubber hose 8 passes through the outer wall of the equipment frame 10 and is fixedly connected to the top of the rotary joint 16.

[0025] Working principle: When the sand mixer is mixing sand, the electric push rod 3 drives the rectangular metal plate 4 and the rectangular rubber piston 5 to move upward. When the rectangular rubber piston 5 moves upward, it causes the water in the double-chamber water tank 2 to be squeezed upward. The water enters the rotary joint 16 from the outlet rubber hose 8, and then enters the vertical pipe 11 from the rotary joint 16 downward. As the electric motor 14 runs, it drives the gear 15 connected to it to rotate. Through the meshing connection of the two gears 15, the other gear 15 rotates. The rotation of the other gear 15 drives the vertical pipe 11 to rotate. The rotation of the vertical pipe 11 drives the spray pipe 12 and the two nozzles 13 to rotate. When the water is sprayed downward through the spray pipe 12 and the two nozzles 13 (the spray range is fan-shaped), it rotates, thereby achieving the purpose of uniform water addition and improving sand mixing efficiency. After the water addition is completed, the ramp 9 is removed from the top of the sand mixer body 1.

[0026] It should be noted that when actually put into use, an existing PLC controller can be added. The PLC controller is electrically connected to the main body 1 of the sand mixer, the electric push rod 3, and the electric motor 14 to facilitate the control of the overall operation.
