For high-temperature material conveying devices for sodium hexametaphosphate

Abstract

This utility model provides a high-temperature material conveying device for sodium hexametaphosphate, including a conveying shell with a rotating main shaft on it. One end of the main shaft has a coarse crushing and agitating mechanism, and the other end has a spiral agitator. The coarse crushing and agitating mechanism includes multiple sleeve plates, each with a telescopic straight agitator. An arc-shaped water plate is provided on the conveying shell. Water flows through the arc-shaped cavity of the arc-shaped water plate to cool the sodium hexametaphosphate in the overall structure, preventing jamming, high-temperature material escaping to the drive end causing bearing damage, deformation of the spiral conveyor main shaft after long-term high-temperature operation, and a high overall device failure rate. Adjusting the distance between the straight agitator and the conveying shell prevents deformation of metal components such as the straight agitator and the conveying shell due to differences in thermal expansion coefficients, as the agitator and the shell can also cause jamming.

Description

Technical Field

[0001] This utility model relates to the field of sodium hexametaphosphate production, and in particular to a high-temperature material conveying device for sodium hexametaphosphate. Background Technology

[0002] The sodium hexametaphosphate process involves dissolving sodium carbonate, phosphoric acid, or other mixed phosphates to form a slurry, the main components of which are disodium hydrogen phosphate and sodium hydrogen phosphate. After being heated in a melting furnace, the slurry is converted into high-temperature liquid sodium hexametaphosphate and transported to downstream equipment.

[0003] Existing methods for conveying high-temperature sodium hexametaphosphate use screw conveyors, but these are prone to jamming, high-temperature material escaping to the drive end causing bearing damage, and deformation of the screw conveyor shaft after prolonged high-temperature operation, resulting in a high overall failure rate. Furthermore, due to fluctuations in the production process, the temperature of the sodium hexametaphosphate can easily exceed the design range, potentially leading to insufficient expansion clearance and further jamming. Metal components such as the augers and housing can deform due to differences in their coefficients of thermal expansion; the augers and housing can also seize up, affecting the equipment's lifespan. Utility Model Content

[0004] This utility model provides a high-temperature material conveying device for sodium hexametaphosphate, which solves the problems of jamming, high-temperature material escaping to the drive end causing bearing damage, deformation of the screw conveyor main shaft after long-term high-temperature operation, and high overall device failure rate during the high-temperature sodium hexametaphosphate conveying process; at the same time, the temperature of sodium hexametaphosphate is easy to exceed the design range, and the screw blades and the machine casing are prone to seizing.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a high-temperature material conveying device for sodium hexametaphosphate, including a conveying shell, a rotating main shaft on the conveying shell, a coarse crushing and winnowing mechanism at one end of the main shaft, and a spiral winnowing blade at the other end of the main shaft. The coarse crushing and winnowing mechanism includes multiple sleeve plates, and telescopic straight winnowing blades are provided on the sleeve plates. An arc-shaped water plate is provided on the conveying shell.

[0006] In a preferred embodiment, a first motor is provided on one side of the conveyor housing, the output shaft of the first motor is connected to the main shaft, and the main shaft is provided with multiple threaded holes.

[0007] In the preferred embodiment, the conveyor shell has a feed inlet at one top end and a discharge outlet at one bottom end. The conveyor shell has an observation hole at the discharge outlet and a cleaning hole at the feed inlet. A cleaning plate is provided at the bottom of the cleaning hole. An arc-shaped shell is provided on the conveyor shell, and the arc-shaped shell is connected to the conveyor shell by a third bolt.

[0008] In a preferred embodiment, the arc-shaped water plate includes an outer shell, an arc-shaped cavity inside the outer shell, an inlet at one end of the outer shell, and an outlet at the other end of the outer shell.

[0009] In the preferred embodiment, the inlet and outlet are connected to the water tank via water pipes, and a water pump is installed between the water tank and the inlet.

[0010] In a preferred embodiment, the coarse crushing and winch mechanism includes a sleeve with multiple circumferentially arrayed plates on the sleeve and grooves on the plates, with the straight plate winch blade sliding against the grooves.

[0011] In the preferred embodiment, the sleeve rests against the main shaft, and the sleeve is provided with multiple second holes. The second bolt passes through the second holes and the threaded hole in sequence, and the second bolt is connected to the threaded hole.

[0012] In the preferred embodiment, the sleeve plate has grooves on both sides, the straight plate blade has mounting holes on both sides, the first bolt passes through the groove and the mounting hole, and the first bolt is connected to the nut.

[0013] In the preferred embodiment, a swivel plate is provided at one end of the straight blade, and rounded corners are provided on both sides of the swivel plate.

[0014] The beneficial effects of this utility model are as follows: When the overall structure needs to convey high-temperature sodium hexametaphosphate, the material is fed into the feed inlet, the sleeve is connected to the main shaft through the second bolt, and the first motor is driven to make the main shaft rotate, so that the coarse crushing winch mechanism and the spiral winch blade rotate, so that the coarse crushing winch mechanism coarsely crushes the sodium hexametaphosphate, and the spiral winch blade carries the material to the discharge port. At the same time, the water pump is driven to make water flow in the arc cavity of the arc water plate to cool down the sodium hexametaphosphate in the overall structure, so as to avoid jamming, high-temperature material escaping to the drive end causing bearing damage, deformation of the spiral conveyor main shaft after long-term high-temperature operation, and high failure rate of the overall device.

[0015] When the temperature of sodium hexametaphosphate exceeds the design range and the expansion gap changes, the entire process is stopped. The arc-shaped shell is disassembled, and the operator removes the second bolt to disengage the coarse crushing winch mechanism from the main shaft. Then, the first bolt is loosened, and the position of the straight plate winch blades is readjusted to adjust the gap between the straight plate winch blades and the conveyor shell. By rotating the sleeve one revolution, the position of multiple straight plate winch blades can be adjusted. After all the straight plate winch blades have been adjusted, the sleeve is installed on the main shaft, and the arc-shaped shell is installed to adjust the gap between the straight plate winch blades and the conveyor shell. This prevents the straight plate winch blades, conveyor shell, and other metal parts from deforming due to differences in thermal expansion coefficients, as the winch blades and the casing can also cause seizure.

[0017] Example 1: like Figure 1-6 In the middle, a high-temperature material conveying device for sodium hexametaphosphate includes a conveying shell 1, a rotating main shaft 3 on the conveying shell 1, a coarse crushing and winch mechanism 5 at one end of the main shaft 3, and a spiral winch blade 6 at the other end of the main shaft 3. The coarse crushing and winch mechanism 5 includes multiple sleeve plates 502, and telescopic straight winch blades 503 are provided on the sleeve plates 502. An arc-shaped water plate 4 is provided on the conveying shell 1. With this structure, when the overall structure needs to convey high-temperature sodium hexametaphosphate, the material is fed into the feed inlet 101. The sleeve 501 is connected to the main shaft 3 through the second bolt 7, driving the first motor 2 to make the main shaft 3 rotate, which in turn makes the coarse crushing winch mechanism 5 and the spiral winch blade 6 rotate, so that the coarse crushing winch mechanism 5 coarsely crushes the sodium hexametaphosphate, and the spiral winch blade 6 carries the material to the discharge outlet 102. At the same time, the water pump is driven to make water flow in the arc cavity 402 of the arc water plate 4, so as to cool the sodium hexametaphosphate of the overall structure and avoid jamming, high-temperature material escaping to the drive end causing bearing damage, deformation of the spiral conveyor main shaft after long-term high-temperature operation, and high failure rate of the overall device.

[0018] When the temperature of sodium hexametaphosphate exceeds the design range and the expansion gap changes, the entire process is stopped. The arc-shaped shell 105 is disassembled. The operator removes the second bolt 7 to disengage the coarse crushing winch mechanism 5 from the main shaft 3. Then, the first bolt 504 is loosened, and the position of the straight plate winch blade 503 is readjusted to adjust the gap between the straight plate winch blade 503 and the conveying shell 1. By rotating the sleeve 501 one turn, the position of multiple straight plate winch blades 503 can be adjusted. After the position of all straight plate winch blades 503 is adjusted, the sleeve 501 is installed on the main shaft 3, and the arc-shaped shell 105 is installed to adjust the gap between the straight plate winch blade 503 and the conveying shell 1. This prevents the metal parts such as the straight plate winch blade 503 and the conveying shell 1 from deforming due to the difference in thermal expansion coefficients. The winch blade and the shell can also cause seizure.

[0019] In a preferred embodiment, a first motor 2 is provided on one side of the conveying housing 1. The output shaft of the first motor 2 is connected to the main shaft 3, and the main shaft 3 is provided with multiple threaded holes 301. With this structure, the main shaft 3 is connected to the sleeve 501 of the coarse crushing and winnowing mechanism 5 through the threaded holes 301.

[0020] In the preferred embodiment, the conveying shell 1 has a feed inlet 101 at one top end and a discharge outlet 102 at one bottom end. An observation hole 103 is located at the discharge outlet 102, and a cleaning hole 104 is located at the feed inlet 101. A cleaning plate is located at the bottom of the cleaning hole 104. An arc-shaped shell 105 is mounted on the conveying shell 1, and the arc-shaped shell 105 is connected to the conveying shell 1 by a third bolt. With this structure, if jamming occurs during the conveying of high-temperature sodium hexametaphosphate, the cleaning plate at the bottom of the cleaning hole 104 can be removed to clean the material at the end of the first motor 2, preventing equipment damage. The cleaning plate is connected to the conveying shell 1 by a fourth bolt.

[0021] In the preferred embodiment, the arc-shaped water plate 4 includes a housing 401, an arc-shaped cavity 402 inside the housing 401, a liquid inlet 403 at one end of the housing 401, and a liquid outlet 404 at the other end. With this structure, by driving a water pump, water flows through the arc-shaped cavity 402 of the arc-shaped water plate 4, thereby cooling the sodium hexametaphosphate in the overall structure. This prevents jamming, high-temperature material escaping to the drive end causing bearing damage, deformation of the screw conveyor shaft after long-term high-temperature operation, and a high overall device failure rate.

[0022] In the preferred embodiment, the inlet 403 and the outlet 404 are connected to the water tank via water pipes, and a water pump is provided between the water tank and the inlet 403.

[0023] In a preferred embodiment, the coarse crushing agitator 5 includes a sleeve 501, on which a plurality of circumferentially arrayed plates 502 are provided. Each plate 502 has a sliding groove 5021, and straight blades 503 slide against the sliding groove 5021. With this structure, the straight blades 503 slide against the sliding groove 5021, and the plurality of straight blades 503 are used for the initial crushing of the material.

[0024] In the preferred embodiment, the sleeve 501 abuts against the main shaft 3, and the sleeve 501 is provided with a plurality of second holes 5011. The second bolt 7 passes through the second hole 5011 and the threaded hole 301 in sequence, and the second bolt 7 is connected to the threaded hole 301. With this structure, when the temperature of sodium hexametaphosphate exceeds the design range and the expansion gap changes, the entire process stops, the arc shell 105 is disassembled, and the operator removes the second bolt 7 to disengage the coarse crushing winch mechanism 5 from the main shaft 3. Then, the first bolt 504 is loosened, and the position of the straight plate winch blade 503 is readjusted to adjust the gap between the straight plate winch blade 503 and the conveying shell 1. By rotating the sleeve 501 one turn, the position of multiple straight plate winch blades 503 can be adjusted. After all the straight plate winch blades 503 have been adjusted, the sleeve 501 is installed on the main shaft 3, and the arc shell 105 is installed to adjust the gap between the straight plate winch blade 503 and the conveying shell 1. This prevents the straight plate winch blade 503, the conveying shell 1, and other metal parts from deforming due to differences in thermal expansion coefficients. The winch blades and the machine casing can also cause seizure.

[0025] In the preferred embodiment, the sleeve plate 502 has grooves 5021 on both sides, and the straight plate auger 503 has mounting holes 5031 on both sides. The first bolt 504 passes through the groove 5022 and the mounting hole 5031, and is connected to the nut. With this structure, in the preferred embodiment, this device can also control the particle size of the initial material by adjusting the distance between the straight plate auger 503 and the conveying shell 1.

[0026] In the preferred embodiment, the straight blade 503 has a screw plate 5032 at one end, and the screw plate 5032 has rounded corners on both sides. With this structure, the rounded corners on both sides of the screw plate 5032 facilitate the screw plate 5032 in crushing materials.

That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
