Description

Technical Field

[0001] This utility model belongs to the field of cooling devices for cast steel processing, and specifically relates to a high-efficiency cooling device for cast steel processing. Background Technology

[0002] Castings produced in the automotive, aerospace, energy, metallurgical, and construction industries have high requirements for hardness, strength, and wear resistance. Ordinary cast iron cannot meet these requirements, and cast steel is often needed to manufacture the relevant castings. During the manufacturing process, the castings need to be cooled.

[0003] Currently, existing cooling methods for cast steel processing often involve immersing the cast steel in cold water to lower its temperature. However, because the cold water in the cold water tank does not flow for a long time, the cooling effect decreases, resulting in low cooling efficiency for the cast steel.

[0004] Therefore, to address the problem that the existing cooling device reduces the cooling effect by immersing the cast steel in a cold water tank during cooling, where the cold water in the tank does not circulate, an improvement is made to the existing cooling device. Spray heads are installed in the cold water tank, with the pipes of the spray heads located inside the tank. This allows the device to draw cold water from the tank and pour it onto the surface of the cast steel, thereby improving the cooling effect. Utility Model Content

[0005] To overcome the problem that the cooling effect is reduced when the cast steel is immersed in a cold water tank during the cooling process, due to the lack of flow of cold water in the tank.

[0006] The technical solution of this utility model is as follows: a high-efficiency cooling device for cast steel processing, including a cold water tank, an irregularly shaped filter box, a spray head, and a water pumping pipe; the irregularly shaped filter box is installed in the cold water tank, which is composed of a box formed by three filter screens and two support plates and a support frame formed by four baffles fixedly connected to the outside of the filter box; a spray head is installed on the irregularly shaped filter box, and a water pumping pipe installed in the cold water tank is connected to the spray head; a pump is built into one end of the water pumping pipe.

[0007] Preferably, by installing a spray head and a water pumping pipe above the irregularly shaped filter box, cold water is drawn from the cold water pool through the water pumping pipe and sprayed onto the cast steel from above, thereby accelerating the flow of cold water in the cold water pool and cooling the cast steel from above, thus improving the effect of the cast steel cooling device.

[0008] Preferably, the support frame of the irregularly shaped filter box has left and right opposite inlet and outlet water pipes, with pumps built into the inlet and outlet water pipes. A fixing ring is set on the cold water pool, and the water pumping pipe is inserted into the fixing ring. The support frame of the irregularly shaped filter box divides the area in the cold water pool into two parts. The water in the outer box and the inner box of the support frame can be exchanged through the inlet and outlet water pipes with built-in pumps, which can accelerate the flow of cold water inside and outside the support frame and improve the cooling efficiency.

[0009] Preferably, a chute is provided on the rear side of the cold water tank, and a slider is slidably connected in the chute. The slider is fixedly connected to the bottom end of the fixed ring. By moving the slider in the chute, the fixed ring installed on the slider and the water pumping pipe inserted in the fixed ring and connected to the spray head move left and right in the cold water tank together, so as to cool down the cast steel with the moving length.

[0010] Preferably, a No. 1 threaded rod is inserted into the slide groove, and a threaded hole matching the No. 1 threaded rod is opened on the slider. A No. 1 motor connected to the No. 1 threaded rod is installed on one side of the cold water pool. The No. 1 motor drives the No. 1 threaded rod to rotate. Due to the restriction of the slide groove, the slider screwed to the No. 1 threaded rod cannot rotate with the No. 1 threaded rod, but moves along the No. 1 threaded rod.

[0011] As a preliminary option, a lifting platform is fixedly connected to the front of the irregularly shaped filter box. A No. 2 threaded rod is installed in the cold water tank. A limit post is fixedly connected in the cold water tank. A screw hole matching the No. 2 threaded rod is opened on the lifting platform. The lifting platform is sleeved on the outside of the limit post. After the No. 2 threaded rod rotates, under the restriction of the limit post, the lifting platform screwed on the No. 2 threaded rod cannot rotate with the No. 2 threaded rod, but moves up and down along the limit post.

[0012] As a preferred option, a second motor is installed at the bottom of the cold water tank. The transmission element of the second motor is connected to the second threaded rod. The second motor provides power for the rotation of the second threaded rod, thereby enabling the irregularly shaped filter box and the cast steel inside the box, which are fixedly connected to the lifting platform, to move upward together, making it convenient to remove the cast steel from the cold water tank.

[0013] As a preferred option, a waterproof cover is installed at the bottom of the cold water tank, and the No. 2 threaded rod is movably inserted into the waterproof cover. A water baffle plate is fixedly connected to the No. 2 threaded rod and closely attached to the inside of the waterproof cover. The waterproof cover and the water baffle plate can isolate the No. 2 motor from the cold water in the cold water tank, thus protecting the No. 2 motor.

[0014] The beneficial effects of this utility model are:

[0015] 1. By installing a spray head and a water pumping pipe above the irregularly shaped filter box, cold water is drawn from the cold water pool through the water pumping pipe and sprayed onto the cast steel from above. This accelerates the flow of cold water in the cold water pool and cools the cast steel from above, thereby improving the efficiency of the cast steel cooling device, reducing the time required to cool the cast steel, and achieving rapid cooling.

[0016] 2. The No. 1 motor drives the No. 1 threaded rod to rotate, so that the slider drives the spray head to move laterally in the cold water pool, thereby cooling the cast steel of a certain length. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figure 1 - Figure 6 This utility model provides an embodiment: a high-efficiency cooling device for cast steel processing includes a cold water tank 1, a shaped filter box 2, a spray head 3, and a water extraction pipe 4; the shaped filter box 2 is installed in the cold water tank 1, and the shaped filter box 2 is composed of a box formed by three filter screens and two support plates, and a support frame formed by four baffles fixedly connected to the outside of the filter box; the shaped filter box 2 is equipped with a spray head 3, and the water extraction pipe 4 is connected to the spray head 3 and installed in the cold water tank 1; one end of the water extraction pipe 4 is equipped with a pump; by installing the spray head 3 and the water extraction pipe 4 above the shaped filter box 2, cold water in the cold water tank 1 is drawn through the water extraction pipe 4 and sprayed and rinsed on the cast steel from above, thereby accelerating the flow of cold water in the cold water tank 1 and cooling the cast steel from above, thereby improving the effect of the cast steel cooling device.

[0026] Please see Figure 2 - Figure 5In this embodiment, the support frame of the irregularly shaped filter box 2 has left and right opposite inlet and outlet water pipes 5, each containing a pump. A fixing ring 6 is installed on the cold water tank 1, and a water suction pipe 4 is inserted into the fixing ring 6. A sliding groove 7 is provided on the rear side of the cold water tank 1, and a slider 8 is slidably connected within the groove 7. The slider 8 is fixedly connected to the bottom end of the fixing ring 6. A first-order threaded rod 9 is inserted into the groove 7, and a threaded hole matching the first-order threaded rod 9 is provided on the slider 8. A first-order motor 10, a transmission element connected to the first-order threaded rod 9, is installed on one side of the cold water tank 1. The support frame of the irregularly shaped filter box 2 divides the area within the cold water tank 1 into two parts. The water inlet and outlet pipes 5 of the built-in pump can exchange the water inside the support frame and the outer box of the support frame, accelerate the flow of cold water inside and outside the support frame, and improve the cooling efficiency. The slider 8 moves in the slide groove 7, which drives the fixing ring 6 installed on the slider 8 and the water pumping pipe 4 inserted in the fixing ring 6 and connected to the spray head 3 to move left and right in the cold water pool 1, so as to cool the cast steel with the moving length. The first motor 10 drives the first threaded rod 9 to rotate. Under the restriction of the slide groove 7, the slider 8 screwed on the first threaded rod 9 cannot rotate with the first threaded rod 9, but moves along the first threaded rod 9.

[0027] Please see Figure 5 - Figure 6 In this embodiment, a lifting platform 11 is fixedly connected to the front side of the irregularly shaped filter box 2. A second threaded rod 12 is provided inside the cold water tank 1. A limiting post 13 is fixedly connected inside the cold water tank 1. A threaded hole matching the second threaded rod 12 is opened on the lifting platform 11. The lifting platform 11 is sleeved on the outside of the limiting post 13. A second motor 14 is installed at the bottom of the cold water tank 1. The transmission element of the second motor 14 is connected to the second threaded rod 12. A waterproof cover 15 is installed at the bottom of the cold water tank 1. The second threaded rod 12 is movably inserted into the waterproof cover 15. A fastener tightly attached to the inside of the waterproof cover 15 is fixedly connected to the second threaded rod 12. After the baffle plate 16 and the second threaded rod 12 rotate, under the restriction of the limit post 13, the lifting platform 11 screwed onto the second threaded rod 12 cannot rotate with the second threaded rod 12, but moves up and down along the limit post 13. The second motor 14 provides power for the rotation of the second threaded rod 12, thereby changing the shape of the filter box 2 fixedly connected to the lifting platform 11 and the cast steel inside the box to move upward together, making it easier to remove the cast steel from the cold water pool 1. The waterproof cover 15, together with the baffle plate 16, can separate the second motor 14 from the cold water in the cold water pool 1, thus protecting the second motor 14.

[0028] During operation, the worker first attaches the waterproof cover 15 to the outside of the threaded rod, then installs the motor at the bottom of the threaded rod, and then installs the motor in the cold water tank 1. The waterproof cover 15 is moved so that the inside of the waterproof cover 15 is tightly against the bottom of the baffle plate 16 and the waterproof cover 15 is fixed. Then, cooling water is introduced into the cold water tank 1, and the processed cast iron is poured into the irregular filter box 2. The second motor 14 is started, and the second motor 14 drives the second threaded rod 12 to rotate. Under the restriction of the second limit post 13, the irregular filter box 2, which is fixedly connected to the lifting platform 11, moves downward with the cast steel and immerses the cast steel in the water. The cooling water flows from the outside of the support frame to the inside and then out through the inlet and outlet water pipes 5, realizing the flow of cold water.

[0029] Start motor 10, which drives threaded rod 9 to rotate. Under the constraint of slide groove 7, slider 8, which is screwed onto threaded rod 9, moves with spray head 3 and water pipe 4 in cold water tank 1. Water pipe 4 draws cold water from cold water tank 1 through built-in pump and sprays it onto the surface of cast steel to cool it down. After cooling is completed, start motor 14, which drives lifting platform 11 and irregular filter screen to move upward to facilitate the removal of cast steel.

[0030] Through the above steps, a spray head 3 and a water pumping pipe 4 are installed above the irregularly shaped filter box 2. Cold water in the cold water pool 1 is drawn through the water pumping pipe 4 and sprayed onto the cast steel from above. This accelerates the flow of cold water in the cold water pool 1 and cools the cast steel from above, thereby improving the efficiency of the cast steel cooling device, reducing the time required to cool the cast steel, and achieving rapid cooling. This solves the problem that when the cast steel is cooled by immersing it in the bottom of the cold water pool 1 during the existing casting steel processing, the cooling effect is reduced because the cold water in the cold water pool 1 does not flow.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
