Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary equipment for cast iron pipe production, and in particular to a system for treating residual iron bars in the flow channel of a cast iron pipe centrifuge. Background Technology
[0002] During the production process of cast iron pipe centrifuges, molten iron is poured into the pipe mold inside the centrifuge through a long trough (approximately 6 meters). As the molten iron flows through the trough, residual molten iron and iron slag remain at the bottom of the trough. After slight cooling, these residues form relatively long iron bars. After each cast iron pipe is poured, the trough is moved to one side by a pouring trolley, and then rotated 180 degrees by a trough tilting mechanism to pour out the iron bars. A collection trough is located below to collect the iron bars.
[0003] Currently, centrifuges directly pour residual iron bars into a collection tank. Each time the tank is full, a crane is needed to remove it for cleaning. This process of handling residual iron bars impacts centrifuge production, is time-consuming and labor-intensive, and occurs frequently, thus affecting the production efficiency of cast iron pipes. This impact is particularly pronounced in multi-station centrifuge layouts, significantly consuming crane time and affecting the efficiency of other tasks. Utility Model Content
[0004] This invention primarily addresses the technical problem that current centrifuges directly pour residual iron bars into the collection tank, requiring a crane to remove and clean the tank when it is full. This process disrupts centrifuge production, is time-consuming and labor-intensive, and involves a high processing frequency, thus impacting the production efficiency of cast iron pipes. The invention proposes a residual iron bar processing system for cast iron pipe centrifuge troughs. This system automatically crushes, transports, and collects residual iron bars from the troughs, improving the utilization rate of the collection tank, reducing personnel time and effort in transportation, and increasing production efficiency.

[0006] The residual iron transport chain is arranged below multiple crushing guide mechanisms;

[0010] The outlet of the first branch guide trough is located above the residual iron transport chain.
[0011] Preferably, a temporary collection trough is provided below the outlet of the second branch guide trough; the temporary collection trough is located next to the scrap iron transport chain.

[0023] This invention provides a system for handling residual iron bars in the trough of a cast iron pipe centrifuge. The system uses a residual iron bar crushing device to break irregular residual iron bars into shorter bars of similar length. These shorter bars are then transported via inclined and branching guide troughs into a residual iron transport chain, and finally collected in a residual iron collection trough. This invention automatically crushes, transports, and collects residual iron bars in the trough. The processing results in smaller and more uniform residual iron bars in the collection trough, allowing it to hold more bars, facilitating cleaning, preventing blockages, reducing the frequency of cleaning, and increasing the utilization rate of the collection trough. This significantly reduces the workload and labor costs associated with manually cleaning residual iron bars in the trough, thereby improving production efficiency. The waste iron transport chain can be designed for a long transport distance. This utility model can be used in parallel with multi-station centrifuges. Multiple crushing and guiding mechanisms can be arranged at multiple centrifuge stations without occupying the centrifuge's production time. They can work simultaneously without interfering with each other and without affecting the centrifuge's production rhythm, which greatly improves the production efficiency and output of cast iron pipes. It has a wide range of application prospects. Attached Figure Description

[0032] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.
[0033] like Figure 1-3 As shown in the embodiment of this utility model, the residual iron bar processing system for a cast iron pipe centrifuge trough includes: a residual iron transport chain 6 and multiple crushing and guiding mechanisms.
[0034] The residual iron transport chain 6 is arranged below multiple crushing guide mechanisms. A residual iron collection trough 5 is provided at the output end of the residual iron transport chain 6. The residual iron transport chain 6 can input the crushed short residual iron bars into the residual iron collection trough 5. This utility model is designed for a multi-station centrifuge layout, where multiple crushing guide mechanisms can be arranged at multiple centrifuge stations, and each centrifuge station can be equipped with one or two crushing guide mechanisms.
[0035] Each crushing and guiding mechanism includes: a residual iron bar crushing device 2, an inclined guide trough 3, and a branching guide trough 4; the residual iron bar crushing device 2 is arranged directly below the turning station of the flow channel 1; the residual iron bar crushing device 2 is arranged along the axial direction of the flow channel 1, and its length is sufficient to completely receive the residual iron bar. An inclined guide trough 3 is provided below the residual iron bar crushing device 2; the inclined guide trough 3 is funnel-shaped. An inclined guide trough outlet is provided at the bottom center of the inclined guide trough 3, and a branching guide trough 4 is provided at the inclined guide trough outlet.
[0036] The branching guide trough 4 has a first branching guide trough outlet and a second branching guide trough outlet arranged in opposite directions; an outlet inclined baffle is rotatably installed inside the branching guide trough 4; the outlet inclined baffle blocks either the first branching guide trough outlet or the second branching guide trough outlet; the first branching guide trough outlet is located above the scrap iron conveyor chain 6. A temporary collection trough 7 is provided below the second branching guide trough outlet; the temporary collection trough 7 is located beside the scrap iron conveyor chain 6. The outlet inclined baffle can be manually adjusted to change the outlet direction of the branching guide trough 4, allowing one of the two outlets of the branching guide trough 4 to be open while the other is closed; adjusting the outlet inclined baffle to block the second branching guide trough outlet and opening the first branching guide trough outlet allows the broken short scrap iron bars to fall onto the scrap iron conveyor chain 6; adjusting the outlet inclined baffle to block the first branching guide trough outlet and opening the second branching guide trough outlet allows the broken short scrap iron bars to fall into the temporary collection trough 7.
[0037] The residual iron bar crushing device 2 of the crushing guide mechanism in this embodiment can automatically crush the residual iron bars in the flow channel, and guide the crushed short residual iron bars into the residual iron transport chain 6 or the temporary collection tank 7 through the inclined guide 3 and the branch guide 4.
[0038] Specifically, such as Figure 4-7 As shown, the residual iron bar crushing device 2 includes: a crushing device trough 204, a motor 206, a rotating shaft 205, and multiple shearing plates 212. The top and bottom surfaces of the crushing device trough 204 are both open. The crushing device trough 204 is installed directly below the turning station of the flow channel 1. The open top surface of the crushing device trough 204 is used to catch residual iron bars falling from the flow channel 1, and the open bottom surface of the crushing device trough 204 is used to allow short residual iron bars crushed by the residual iron bar crushing device 2 to fall into the inclined guide trough 3.
[0039] Multiple shearing plates 212 are installed in the lower part of the crushing device trough 204; each shearing plate 212 has a shearing blade for crushing residual iron bars. A rotating shaft 205 is installed axially inside the crushing device trough 204; multiple rotating shaft teeth 213 are distributed on the rotating shaft 205, which are used to agitate the residual iron bars and assist in crushing them. A motor 206 is installed at one end of the crushing device trough 204; the output shaft of the motor 206 is connected to the rotating shaft 205. Rotation of the output shaft of the motor 206 drives the rotating shaft 205 to rotate.
[0040] Guide plates 209 are respectively installed on both sides of the upper part of the crushing device trough 204. The guide plates 209 guide the residual iron bars so that they fall above the rotating shaft 205 and the shearing plate 212. One side of the guide plate 209 has an opening for the rotation of the rotating shaft teeth 213. The guide plates 209 are installed on the crushing device trough 204 by multiple connecting bent plates 203. The connecting bent plates 203 are angular; one mounting surface of the connecting bent plate 203 is fixed to the crushing device trough 204, and the other mounting surface fixes the guide plate 209.
[0041] The output shaft of the motor 206 is connected to the rotating shaft 205 via a coupling 201, which is a drum-tooth coupling. Bearing seats 202 are provided at both ends of the rotating shaft 205. The bearing seats 202 are SN-type bearing seats, and self-aligning roller bearings are installed inside. Bearing seat covers 211 are provided outside the bearing seats 202. A motor guard plate 207 is provided outside the motor 206. Additionally, a first baffle 208 is provided at one end of the crushing device trough 204, and a second baffle 210 is provided at the other end. The bearing seat cover 211, motor guard plate 207, first baffle 208, and second baffle 210 protect the corresponding components.
[0042] In this embodiment, when the residual iron bar crushing device 2 is working, the flow channel 1 flips over to flip the residual iron bar onto the residual iron bar crushing device 2. The guide plate 209 on the crushing device channel 204 slides the residual iron bar onto the rotating shaft 205 and the shearing plate 212. With the rotation of the rotating shaft 205 and the rotating shaft teeth 213, short residual iron bars of similar length are sheared, which can crush irregular residual iron bars into residual iron bars of similar length.
[0043] The working process of this utility model's cast iron pipe centrifuge trough residual iron strip processing system is as follows: The trough 1 is moved to the top of the residual iron strip crushing device 2 via a casting trolley. The long residual iron strips inside the trough 1 are poured into the crushing device's trough body 204 by the trough tilting mechanism. The residual iron strip crushing device 2 crushes the residual iron strips. The short residual iron strips after crushing fall into the residual iron transport chain 6 or temporary collection trough 7 via the inclined guide trough 3 and the branching guide trough 4. The short residual iron strips falling onto the residual iron transport chain 6 are finally transported and collected in the residual iron collection trough 5. The residual iron in the residual iron collection trough 5 and the temporary collection trough 7 is periodically replaced and cleaned using a forklift. During normal operation, the first branch channel outlet of the branch channel 4 opens and the second branch channel outlet closes, allowing the broken short iron bars to slide down onto the iron scrap conveyor chain 6 and then be transported to the iron scrap collection tank 5. When the iron scrap conveyor chain 6 is temporarily unable to work due to factors such as temporary malfunction, the second branch channel outlet of the branch channel 4 is adjusted to open and the first branch channel outlet is closed, and the outlet direction of the branch channel 4 is directed toward the temporary collection tank 7, so that the short iron scraps temporarily fall into the temporary collection tank 7.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
