Description

Technical Field

[0001] The utility model relates to the technical field of waste liquid treatment devices, in particular to an organic waste liquid pretreatment device of a low-temperature pyrolysis hot blast furnace. Background Art

[0002] A large amount of waste liquids such as waste mineral oil, waste emulsified oil, and kettle residues are generated in industrial production. These waste liquids usually need to be contained in waste liquid barrels first, and then transported to the waste liquid treatment department of the factory for unified incineration treatment. At present, these waste liquids are usually passed into a hot air furnace for combustion, so as to achieve the reuse of organic waste liquid and save fuel. However, the presence of impurities in the waste liquid is not conducive to the combustion of the waste liquid. Therefore, before the waste liquid is incinerated, it is first necessary to filter out the large particles of impurities in the waste liquid, that is, to filter the waste liquid for pretreatment.

[0003] Patent number CN219964141U discloses a filtering pretreatment device for barreled waste liquid, including a barrel inverting assembly and a filtering assembly; the barrel inverting assembly includes a fixed bracket, a barrel support bracket rotatably arranged on the fixed bracket, a driving member, and a limiting member; the filtering assembly includes a filtering collection tank arranged on the fixed bracket, a filtering member arranged in the filtering collection tank, and an inclined drainage member arranged on the fixed bracket and located between the filtering member and the pouring port on the waste liquid barrel. The pretreatment device can overturn the waste liquid barrel and pour it into the filtering assembly, and the waste liquid is collected for combustion and reuse after being filtered by the filtering assembly. However, when the barrel inverting assembly overturns the waste liquid barrel, it is necessary to manually fix the waste liquid barrel with the barrel support bracket, which is complicated to operate and affects work efficiency; in addition, when the waste liquid barrel is overturned, the waste liquid in the barrel will flow to the barrel support bracket, causing the waste liquid to flow to the barrel support bracket, resulting in a dirty and messy working environment. Utility Model Content

[0004] The utility model provides an organic waste liquid pretreatment device for a low-temperature pyrolysis hot blast furnace, which solves the problem in the prior art that the waste liquid barrel flipping operation is complicated and affects the work efficiency.

[0005] The technical solution of the utility model is achieved in this way:

[0006] An organic waste liquid pretreatment device for a low-temperature pyrolysis hot blast furnace includes a bracket, a filter box is provided on the bracket, a flip platform for placing a waste liquid barrel is movably connected to the bracket, a driving component connected to the flip platform is provided on the bracket, and a hook component for limiting the flip state of the waste liquid barrel is provided on the upper part of the bracket. When the waste liquid barrel is flipped, the hook component can limit the waste liquid barrel to prevent the waste liquid barrel from falling from the flip platform; the waste liquid barrel can be flipped by placing it on the flip platform, and there is no need to set a fastening mechanism on the flip platform, which simplifies the operation steps of flipping the waste liquid barrel and improves work efficiency.

[0007] The hook assembly includes a hook, a crossbar is provided on the upper part of the bracket, a through hole is provided on the crossbar, the hook passes through the through hole upward, a baffle is provided on the upper end of the hook, a spring is sleeved on the hook, and the spring is located between the baffle and the crossbar. When the waste liquid barrel is flipped to a horizontal state, the hook is connected to the edge of the waste liquid barrel, and the waste liquid barrel continues to flip to a downward tilted state, and the hook moves obliquely downward. At this time, the hook limits the waste liquid barrel to prevent the waste liquid barrel from sliding off the flip platform, and when the flip platform returns to its original position, the spring pushes the baffle, so that the baffle drives the hook to return to its original position, and at the same time, the waste liquid in the waste liquid barrel will not flow to the hook, ensuring that the hook assembly is clean and tidy.

[0008] The inner wall of the through hole is an arc-shaped convex surface, which can make the swing of the hook more stable and prevent the hook from being separated from the waste liquid barrel during the overturning process of the waste liquid barrel.

[0009] A first pressure switch is provided at the lower side of the baffle, and the first pressure switch is connected to the driving assembly. The first pressure switch controls the start and stop of the driving assembly. Specifically, when the waste liquid barrel is turned over to an oblique downward state, the first pressure switch on the baffle is pressurized to control the driving assembly to stop. When the pressure on the first pressure switch is the pressure when the waste liquid barrel is in an empty barrel state, the first pressure switch controls the driving assembly to reverse, so that the turning platform swings in the opposite direction to return to its original position.

[0010] The bracket is provided with an inclined guide plate, which is located above the filter box and corresponds to the flip position of the waste liquid barrel. When the waste liquid barrel starts to flip, the waste liquid in the waste liquid barrel is poured onto the guide plate and then enters the filter box for filtration. The setting of the guide plate can prevent the waste liquid from flowing to the flip position, ensuring the cleanliness of the device.

[0011] The flip platform includes a vertical plate and a horizontal plate, the horizontal plate is connected to the lower end of the vertical plate, the upper end of the vertical plate is rotatably connected to the bracket, an inclined rod is arranged between the vertical plate and the horizontal plate, and the inclined rod is connected to the driving assembly; an output conveyor belt and an input conveyor belt are arranged on the side of the horizontal plate, and the output conveyor belt corresponds to the rotation direction of the flip platform. When the horizontal plate swings to a tilted downward state, the waste liquid barrel can slide downward onto the output conveyor belt, which is convenient for the waste liquid barrel to be transferred after being dumped.

[0012] The inner side of the vertical plate is provided with a vertically arranged arc-shaped positioning groove, which cooperates with the waste liquid barrel. When the turning platform turns the waste liquid barrel, the arc-shaped positioning groove positions the waste liquid barrel, ensuring that the waste liquid barrel is accurately positioned on the turning platform and that the hook can be connected to the side of the waste liquid barrel when the waste liquid barrel is turned over.

[0013] A second pressure switch is provided on the top surface of the transverse plate, and the second pressure switch is connected to the driving assembly. The second pressure switch controls the start and stop of the driving assembly. Specifically, when the pressure received by the second pressure switch is less than or equal to the weight of the waste liquid barrel in an empty state, the driving assembly is controlled to start, so that the flip platform swings downward until the transverse plate of the flip platform tilts downward, so that the waste liquid barrel slides down to the output conveyor belt; when the second pressure switch is not subjected to pressure, the driving assembly is controlled to start, so that the flip platform swings upward until the transverse plate of the flip platform is in a horizontal state; when the pressure received by the second pressure switch is greater than the weight of the waste liquid barrel in an empty state, the driving assembly is controlled to start, so that the flip platform swings upward until the waste liquid barrel flips and the waste liquid is dumped into the filter box.

[0014] The driving assembly includes a support beam fixedly connected to the top of the bracket, a winch is provided on the support beam, a suspension rope is wound around the winch, and the suspension rope is connected to the inclined rod. The rotation of the winch can reel in or release the suspension rope, and then the inclined rod is driven to move through the suspension rope, so that the flip platform swings up and down, and the waste liquid in the waste liquid barrel is dumped.

[0015] The filter box is provided with a filter screen; the bottom plane of the filter box is arranged at an angle, and a drain pipe is provided on the filter box, and the drain pipe corresponds to the lowest position of the filter box. When the waste liquid enters the filter box, the filter screen filters the waste liquid, and the inclined bottom surface can make the filtered waste liquid gather at the position of the drain pipe, which is convenient for the discharge of the waste liquid, ensures that the waste liquid is discharged completely, and reduces the waste liquid residue in the filter box.

[0016] The beneficial effects of the utility model are as follows: when the waste liquid barrel is turned over, the hook component can limit the waste liquid barrel to prevent the waste liquid barrel from falling from the turning platform; the waste liquid barrel can be turned over by placing it on the turning platform, and there is no need to set a fastening mechanism on the turning platform, which simplifies the operation steps of turning the waste liquid barrel and improves work efficiency.

[0017] When the waste liquid barrel is flipped to a horizontal state, the hook is connected to the edge of the waste liquid barrel, and the waste liquid barrel continues to flip to a downward tilted state, and the hook moves obliquely downward. At this time, the hook limits the waste liquid barrel to prevent the waste liquid barrel from sliding off the flip platform, and when the flip platform returns to its original position, the spring pushes the baffle, so that the baffle drives the hook to return to its original position. At the same time, the waste liquid in the waste liquid barrel will not flow onto the hook, ensuring that the hook assembly is clean and tidy.

[0018] A first pressure switch is arranged on the baffle plate at the upper end of the hook, and a second pressure switch is arranged on the flip platform. The first pressure switch and the second pressure switch jointly control the start and stop of the driving component, so that the driving component drives the flip platform to swing up and down, thereby enabling the flip platform to be in different working positions, thereby facilitating the automatic flipping and removal of the waste liquid barrel.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1, as Figure 1 , Figure 2As shown, a pretreatment device for organic waste liquid of a low-temperature pyrolysis hot blast furnace comprises a bracket 1, a filter box 2 is arranged on the bracket 1, a flip platform 3 for placing a waste liquid barrel 4 is movably connected to the bracket 1, a driving component connected to the flip platform 3 is arranged on the bracket 1, and a hook component for limiting the flip state of the waste liquid barrel 4 is arranged on the upper part of the bracket 1. The flip platform 3 can drive the waste liquid barrel 4 to flip, and the waste liquid in the waste liquid barrel 4 is poured into the filter box 2 for filtering, and the filtered waste liquid is passed into the hot blast furnace for combustion, and the filtered waste liquid can be more fully burned to achieve the reuse of the waste liquid. In the process of flipping the waste liquid barrel 4 on the flipping platform 3, the hook assembly can limit the waste liquid barrel 4. Specifically, when the waste liquid barrel 4 is flipped to a horizontal state, the waste liquid barrel 4 is connected to the hook assembly, and the flipping platform 3 continues to flip, and the hook assembly limits the waste liquid barrel 4 to prevent the waste liquid barrel 4 from sliding off the flipping platform 3. That is, there is no need to set a fastening mechanism on the flipping platform 3 to perform the flipping action of the waste liquid barrel 4, which simplifies the operating steps of flipping the waste liquid barrel 4 and improves work efficiency.

[0029] Further, if Figure 3 As shown, the hook assembly includes a hook 6, a cross bar 13 is provided on the upper part of the bracket 1, a through hole 131 is provided on the cross bar 13, the hook 6 passes through the through hole 131 upwards, a baffle 61 is provided on the upper end of the hook 6, a spring 62 is sleeved on the hook 6, and the spring 61 is located between the baffle 61 and the cross bar 13. The baffle 61 and the spring 62 cooperate to limit the hook 6, so that the hook 6 is in a vertical state when not subjected to force, and when the waste liquid barrel 4 is turned to a horizontal state, the hook 6 can be connected to the edge of the waste liquid barrel 4, the waste liquid barrel 4 continues to turn to a downward tilted state, and the hook 6 moves obliquely downward. At this time, the hook 6 limits the waste liquid barrel 4 to prevent the waste liquid barrel 4 from sliding off the flip platform 3, and when the flip platform 3 returns to its original position, the spring 62 pushes the baffle 61, so that the baffle 61 drives the hook 6 to return to its original position, and at the same time, the waste liquid in the waste liquid barrel 4 will not flow to the hook 6, ensuring that the hook 4 assembly is clean and tidy.

[0030] Furthermore, the inner wall of the through hole 131 is an arc-shaped convex surface. The arc-shaped convex surface can make the swing of the hook more stable, and prevent the hook from being separated from the waste liquid barrel during the overturning process of the waste liquid barrel.

[0031] Furthermore, a first pressure switch is provided on the lower side of the baffle 61, and the first pressure switch is connected to the driving assembly. The first pressure switch controls the start and stop of the driving assembly, specifically, Figure 4 As shown, when the waste liquid barrel 4 is flipped to a tilted downward state, the first pressure switch on the baffle 62 is pressurized to control the driving assembly to stop. When the pressure applied to the first pressure switch is the pressure when the waste liquid barrel 4 is in an empty barrel state, the first pressure switch controls the driving assembly to reverse, causing the flip platform 3 to swing in the opposite direction and return to its original position.

[0032] Embodiment 2, based on Embodiment 1, is a pretreatment device for organic waste liquid of a low-temperature pyrolysis hot blast furnace, wherein a guide plate 11 arranged obliquely is provided on the bracket 1, and the guide plate 11 is located above the filter box 2, and the guide plate 11 corresponds to the flip position of the waste liquid barrel 4.

The upper part of the vertical plate is rotatably connected to the bracket 1, and the inclined rod connects the vertical plate and the horizontal plate to make the connection between the two stable, thereby ensuring the structural stability of the turning platform 3. When the horizontal plate is in a horizontal state, the horizontal plate is flush with the input conveyor belt 8, and the input conveyor belt 8 can convey the waste liquid barrel 4 containing waste liquid to the turning platform 3. When the horizontal plate is in a tilted downward state, the side of the horizontal plate is flush with the output conveyor belt 7, and the waste liquid barrel 4 can slide downward to the output conveyor belt 7 under the action of its own gravity, which is convenient for realizing the input and output of the waste liquid barrel 4 on the turning platform 3.

[0034] Furthermore, a vertically arranged arc-shaped positioning groove is provided on the inner side of the vertical plate, and the arc-shaped positioning groove cooperates with the waste liquid barrel 4. When the turning platform 3 turns over the waste liquid barrel 4, the arc-shaped positioning groove positions the waste liquid barrel 4, ensuring that the waste liquid barrel 4 is accurately positioned on the turning platform 3, and ensuring that the hook 6 can be connected to the side of the waste liquid barrel 4 when the waste liquid barrel 4 is turned over.

[0035] Furthermore, a second pressure switch is provided on the top surface of the horizontal plate, and the second pressure switch is connected to the driving assembly. The second pressure switch controls the start and stop of the driving assembly, specifically, Figure 6 As shown, when the pressure applied to the second pressure switch is less than or equal to the weight of the waste liquid barrel 4 in an empty barrel state, the control drive component is started to swing the flip platform 3 downward until the cross plate of the flip platform 3 is tilted downward, so that the waste liquid barrel 4 slides down to the output conveyor belt 7; when the second pressure switch is not subjected to pressure, the control drive component is started to swing the flip platform 3 upward until the cross plate of the flip platform 3 is in a horizontal state, at which time the input conveyor belt 8 transfers the waste liquid barrel 4 containing waste liquid to the flip platform 3; when the pressure applied to the second pressure switch is greater than the weight of the waste liquid barrel 4 in an empty barrel state, the control drive component is started to swing the flip platform 3 upward until the waste liquid barrel 4 is flipped to dump the waste liquid into the filter box 2.

[0036] Furthermore, the driving assembly includes a support beam 12 fixedly connected to the top of the bracket 1, a winch 5 is provided on the support beam 12, a suspension rope 51 is wound around the winch 5, and the suspension rope 51 is connected to the inclined rod.
