Description

A type of lead pipe Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, specifically to a lead conveying pipe. Background Technology

[0002] In the lead smelting process, molten lead in a lead pot needs to be transported to a mold for cooling and shaping using conveying equipment. This conveying equipment typically includes a lead-feeding pipe and a lead-feeding pump. After the lead-feeding pump is started, the molten lead enters from the lead pot into the lead-feeding pipe, and then flows through the pipe into the mold.

[0003] When lead transport needs to be stopped, the existing lead transport pipes have long straight sections where molten lead tends to temporarily accumulate. When the transport interval is long, the molten lead easily cools down in these straight sections, necessitating the use of heating equipment to reheat them. Heating these straight sections consumes energy, making the existing lead transport system energy-intensive.

[0004] Existing lead conveying pipes are generally fixed, and the height of one end of the pipe inside the lead pot cannot be changed. When there are many impurities in the molten lead in the lead pot, the slag-containing layer at the bottom of the molten lead is at a high level. During lead conveying, the slag-containing layer can easily pass through the lead conveying pipe, resulting in the quality of the formed lead ingots failing to meet the standards. Summary of the Invention

[0005] The main purpose of this invention is to provide a lead pipe that can reduce energy consumption and extract lead liquid from a set layer as needed.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] A lead conveying pipe includes a first pipe connected to a lead conveying pump, the first pipe being rotatably and sealingly connected to a second pipe via a connecting sleeve, the second pipe being connected to a lead pot, a support rod fixed to the lower end of the connecting sleeve, the support rod being fixed to the ground, the first pipe including a vertical part and a straight part, the vertical part of the first pipe being connected to the lead conveying pump, the straight part of the first pipe being fixedly and sealingly connected to the connecting sleeve, the second pipe including a straight part and an inclined part, the straight part of the second pipe being rotatably and sealingly connected to the connecting sleeve, the inclined part of the second pipe being connected to the lead pot, the end of the inclined part of the second pipe away from the connecting sleeve being inclined downwards, and an adjustment component on the support rod being provided to adjust the inclination angle of the inclined part of the second pipe.

[0008] Specifically, the adjustment assembly includes a rotating rod rotatably connected to the support rod, the rotating rod being parallel to the straight portion of the second pipe, a push rod fixed to one end of the rotating rod, the free end of the push rod contacting the lower side of the inclined portion of the second pipe, and a handle fixed to the other end of the rotating rod. By rotating the rotating rod and the push rod with the handle, the push rod can push the second pipe to rotate around the axis of its straight portion, thereby changing the inclination angle of the inclined portion of the second pipe, ultimately achieving the height of the lower end of the inclined portion of the second pipe inside the lead pot; it also includes a positioning assembly capable of positioning the handle, the rotating rod, and the push rod.

[0009] Specifically, the positioning component includes a fixed rod fixedly connected to the handle bar, the fixed rod being parallel to the rotating rod, a rotating sleeve elastically rotatably connected to the fixed rod, a pawl fixed to the rotating sleeve, a fixed plate fixed to the side of the support rod facing the fixed rod, and multiple baffles fixed in the vertical direction of the fixed plate facing the fixed rod, the multiple baffles being linearly arrayed in the vertical direction of the fixed plate, forming a retaining cavity between adjacent baffles, and the free end of the pawl being engaged in one of the retaining cavities.

[0010] Specifically, the length of the handle is greater than the length of the push rod.

[0011] Specifically, the straight sections of the first pipe and the straight sections of the second pipe are concentric.

[0012] Specifically, the rotating sleeve and the fixed rod are connected by a torsion spring. One end of the torsion spring is fixedly connected to the fixed rod, and the other end of the torsion spring is fixedly connected to the rotating sleeve. Under the restoring torque generated by the torsion spring, the pawl maintains the tendency to rotate in the direction of the support rod.

[0013] Specifically, an insulation layer is provided on the outside of the first pipe, and insulation layers are provided on the outside of the straight section of the second pipe and the upper section of the inclined section of the second pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By coordinating the vertical section of the first pipe and the inclined section of the second pipe, a three-section drainage channel is constructed: when the machine stops, the lead liquid in the inclined section of the second pipe automatically flows back to the lead pot; the lead liquid in the vertical section of the first pipe is discharged vertically by gravity; the residual liquid in the straight section of the first pipe and the straight section of the second pipe is discharged bidirectionally through the connecting structure, eliminating the lead liquid residue of traditional straight pipes and eliminating the need for heating and heat preservation energy consumption.

[0016] 2. The combination of the rotating rod, push rod, and handle rod enables stepless adjustment of the angle of the second pipe inclination section. The handle rod is longer than the push rod, allowing for operation with one hand.

[0017] 3. By adjusting the angle of the inclined part of the second pipe, the inlet of the second pipe can be effectively raised and avoid the slag layer on the lower side of the lead pot, thus preventing the slag layer from entering the second pipe and improving the quality of lead ingots.

[0018] 4. The combination of torsion spring, pawl, and baffle locking mechanism can position the second pipe, making it more convenient to use. Attached Figure Description

[0021] The components in the attached diagram are named as follows: 1. First pipe, 2. Second pipe, 3. Connecting sleeve, 4. Support rod, 5. Rotating rod, 6. Push rod, 7. Handle rod, 8. Fixing plate, 9. Baffle, 10. Fixing rod, 12. Rotating sleeve, 13. Pawl. Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1: Referring to Figures 1-2, a lead conveying pipe includes a first pipe 1 connected to a lead conveying pump. The first pipe 1 is rotatably and sealed to a second pipe 2 via a connecting sleeve 3. The second pipe 2 is connected to a lead pot. A support rod 4 is fixed at the lower end of the connecting sleeve 3 and is fixed to the ground.

[0024] The first pipe 1 includes a vertical section and a horizontal section. The vertical section of the first pipe 1 is connected to the lead pump, and the horizontal section of the first pipe 1 is fixedly and sealed to the connecting sleeve 3.

[0025] The second pipe 2 includes a straight section and an inclined section. The straight section of the second pipe 2 is rotatably and sealingly connected to the connecting sleeve 3. The inclined section of the second pipe 2 is connected to the lead pot. The end of the inclined section of the second pipe 2 away from the connecting sleeve 3 is inclined downward.

[0026] The straight sections of the first pipe 1 and the second pipe 2 are concentric. An insulation layer is provided on the outside of the first pipe 1, and insulation layers are also provided on the outside of the straight section and the upper section of the inclined section of the second pipe 2.

[0027] When the lead pump is started, the molten lead in the lead pot is discharged through the second pipe 2, connecting sleeve 3, and the first pipe 1. When the lead pump stops, the molten lead in the inclined section of the second pipe 2 flows back into the lead pot, while the molten lead in the vertical section of the first pipe 1 is discharged under gravity. The molten lead in the straight sections of the first pipe 1 and the second pipe 2 can be discharged through the vertical section of the first pipe 1 or the inclined section of the second pipe 2. After the lead pump stops, molten lead is prevented from remaining in the first pipe 1 or the second pipe 2, eliminating the need for heating the first and second pipes and reducing energy consumption in the lead conveying process.

[0028] Example 2: Based on Example 1, as shown in Figures 1-2, the support rod 4 is equipped with an adjustment component that can adjust the tilt angle of the inclined part of the second pipe 2.

[0029] The adjustment assembly includes a rotating rod 5 rotatably connected to the support rod 4. The rotating rod 5 is parallel to the straight part of the second pipe 2. A push rod 6 is fixed to one end of the rotating rod 5. The free end of the push rod 6 contacts the lower side of the inclined part of the second pipe 2. A handle 7 is fixed to the other end of the rotating rod 5. The length of the handle 7 is greater than the length of the push rod 6.

[0030] By rotating lever 7, rotating rod 5 and push rod 6 can be turned. Push rod 6 can push the second pipe 2 to rotate around the axis of its straight part, thereby changing the tilt angle of the inclined part of the second pipe 2, and finally realizing the height of the lower end of the inclined part of the second pipe 2 in the lead pot.

[0031] When the liquid level containing slag in the lead pot is high, the lever 7 causes the rotating rod 5 and the push rod 6 to rotate. The free end of the lever 7 rotates downwards, while the free end of the push rod 6 rotates upwards. The push rod 6 causes the second pipe 2 to rotate around its straight section's axis, thereby changing the height of the lower end of the inclined section of the second pipe 2 within the lead pot and increasing the distance between the lower end of the inclined section of the second pipe 2 and the slag-containing layer in the lead pot. After starting the lead pump, this prevents the slag-containing layer from entering the second pipe 2 and being output, thus improving the quality of the lead ingots.

[0032] Example 3: Based on Example 2, referring to Figures 1-2, a lead conveying pipe further includes a positioning assembly capable of positioning the handle 7, the rotating rod 5, and the push rod 6. The positioning assembly includes a fixed rod 10 fixedly connected to the handle 7, the fixed rod 10 being parallel to the rotating rod 5, a rotating sleeve 12 elastically rotatably connected to the fixed rod 10, a pawl 13 fixed to the rotating sleeve 12, a fixed plate 8 fixed to the side of the support rod 4 facing the fixed rod 10, and multiple baffles 9 fixed in the vertical direction of the fixed plate 8 facing the fixed rod 10, the multiple baffles 9 being linearly arrayed in the vertical direction of the fixed plate 8, forming a retaining cavity between adjacent baffles 9, and the free end of the pawl 13 engaging in one of the retaining cavities.

[0033] The rotating sleeve 12 is connected to the fixed rod 10 by a torsion spring. One end of the torsion spring is fixedly connected to the fixed rod 10, and the other end of the torsion spring is fixedly connected to the rotating sleeve 12. Under the restoring torque generated by the torsion spring, the pawl 13 maintains the tendency to rotate in the direction of the support rod 4.

[0034] When the free end of lever 7 rotates downwards, the fixed rod 10, the rotating sleeve 12, and the pawl 13 rotate downwards. Under the restoring torque generated by the torsion spring, the free end of pawl 13 gradually engages with the holding cavity. When the lever 7 stops rotating, the cooperation between the free end of pawl 13 and the holding cavity it is in can position lever 7, rotating rod 5, and push rod 6.

[0035] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
