Description

Technical Field

[0001] The invention relates to the technical field of mixing, in particular to a mixing device for a pre-catalyst for carbonization of oil sludge. Background Art

[0002] In order to promote the decomposition and carbonization reaction of organic matter in the sludge before carbonization, and to reduce the reaction temperature and increase the reaction rate, it is necessary to add some powdered metal oxide catalysts (such as magnesium oxide and calcium oxide) to the sludge. After the catalyst is added to the sludge, the two need to be stirred and mixed in a reactor. A stirring kettle is a common mixing equipment, which achieves the mixing of sludge and catalyst by the rotation of the agitator. When the catalyst is added, the amount of catalyst added to sludges of the same liquid level and different viscosities is generally different. For thinner sludge, its fluidity is better, and the contact between the catalyst and the sludge is relatively easy and uniform, so the amount of catalyst required may be relatively small, because in this case, the catalyst can diffuse and act on the organic matter in the sludge more quickly to promote the carbonization reaction, while for thick sludge, due to its poor fluidity, the catalyst The catalyst is difficult to fully diffuse and evenly mix. In order to ensure that there are enough catalysts in the entire sludge system to initiate and promote the carbonization reaction, it is often necessary to add more catalysts. The fluidity of thick sludge is poor. Therefore, when adding the catalyst, it is necessary to add it in small amounts and multiple times, so that the catalyst can be gradually dispersed at different positions, increase the chance of contact with the sludge, and improve the mixing uniformity. For sludge with lower viscosity and good fluidity, adding small amounts and multiple times can reduce the number of adding operations and improve work efficiency. In the prior art, when adding catalysts, most of them are added manually. When adding catalysts manually, it is difficult to accurately determine the appropriate amount of addition according to the viscosity of the sludge. For thinner sludge, too much catalyst may be added due to inaccurate judgment, resulting in waste. For thick sludge, insufficient catalyst may be added, affecting the carbonization reaction effect.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0035] Example 1

[0036] Reference Figure 1-Figure 11 , which is the first embodiment of the present invention, provides a sludge carbonization pre-catalyst mixing device, the sludge carbonization pre-catalyst mixing device includes a mixing assembly 100, including a tank body 101, a top cover 102 is arranged on the top of the tank body 101, and a stirring mechanism 103 is arranged in the tank body 101.

[0037] The tank body 101 is used to store the sludge. A feed port and a discharge port are respectively provided on the tank body 101. When the sludge is injected into the tank body 101 and the catalyst is added, the sludge can be stirred by the stirring mechanism 103, so that the sludge and the catalyst can be mixed, thereby reducing the reaction temperature and increasing the reaction rate during the carbonization process of the sludge.

[0038] The feeding assembly 200 is arranged on the top of the top cover 102, and includes a storage tank 201. The storage tank 201 is located above the top cover 102. A discharge pipe 202 is fixed to the bottom of the storage tank 201. A baffle plate 203 is rotatably connected to the discharge pipe 202 through a rotating shaft. A partition plate 204 is fixed in the storage tank 201, and a spiral feeder 205 is arranged on the partition plate 204. The bottom end of the discharge pipe 202 extends into the tank body 101 and is fixed to the top cover 102.

[0039] The storage tank 201 is used to store powdered catalysts. The bottom of the storage tank 201 is conical, and the discharge pipe 202 is connected to the storage tank 201 .

[0040] When the spiral feeder 205 is rotating, the catalyst above the partition plate 204 can be transported to the bottom of the partition plate 204 and accumulated above the discharge pipe 202. When the baffle plate 203 is rotated and opened, the catalyst can fall into the tank body 101 through the discharge pipe 202, thereby completing the addition of the catalyst.

[0041] There are two groups of spiral feeders 205, which are respectively located on both sides of the partition plate 204. The two groups of spiral feeders 205 are connected by belts and pulleys. The two groups of spiral feeders 205 can rotate simultaneously when rotating, so that a sufficient amount of catalyst can be dropped when the catalyst is fed. A protective box is provided on the outside of the belt and pulley to prevent the catalyst from contacting the belt and pulley, which may cause the two to get stuck.

[0042] When the viscosity of the sludge is too high, the screw feeder 205 will rotate more times, so that more catalyst can be transported to the bottom of the partition plate 204, and more catalyst can be added to the sludge with too high viscosity, thereby ensuring that there is enough catalyst in the entire sludge system to initiate and promote the carbonization reaction.

[0043] When the viscosity of the sludge is too low and there is no need to add too much catalyst, the spiral feeder 205 will rotate fewer times, and less catalyst will be transported to the bottom of the partition plate 204, thereby saving the amount of catalyst used.

[0044] When the viscosity of the sludge is too high, the baffle plate 203 will be opened for a shorter time each time it is rotated to open, so that the amount of catalyst falling downward can be reduced, so that the catalyst can be gradually dispersed at different positions, increasing the chance of contact with the sludge and improving mixing uniformity.

[0045] When the viscosity of the oil sludge is too low, the baffle plate 203 will be opened for a longer time each time it is rotated and opened, so that a larger amount of catalyst can fall downward, thereby improving the mixing efficiency of the oil sludge and the catalyst.

[0046] The transmission assembly 300 is arranged on the top cover 102, and includes a rotating member 301. The rotating member 301 includes a rotating column 301a. The rotating column 301a is rotatably connected to the top cover 102 through a bearing. A movable column 301b is movably connected inside the rotating column 301a. A connecting column 301c is rotatably connected to the top of the movable column 301b through a bearing. A first fixed shaft 301d is fixed to one side of the connecting column 301c. A first spiral groove 205-1 is opened in the spiral feeder 205, and the first fixed shaft 301d slides in the first spiral groove 205-1.

[0047] When the movable column 301b moves upward, it will drive the connecting column 301c to move upward, and drive the first fixed shaft 301d to slide in the first spiral groove 205-1 through the connecting column 301c. Through the cooperation of the two, the spiral feeder 205 can be driven to rotate, so that the catalyst above the partition plate 204 can be transported to the bottom of the partition plate 204 through the spiral feeder 205.

[0048] The more the movable column 301b moves upward, the more turns the spiral feeder 205 rotates, and the more catalyst is transported downward. Conversely, the less the movable column 301b moves upward, the fewer turns the spiral feeder 205 rotates, and the less catalyst is transported downward.

[0049] The pitch of the first spiral groove 205 - 1 is small, so the movable column 301 b moves upward with a small stroke, and the spiral feeder 205 can be driven to rotate more circles through the cooperation between the first fixed shaft 301 d and the first spiral groove 205 - 1 .

[0050] The transmission assembly 300 also includes a pushing member 302, which is arranged on the movable column 301b, including a push rod 302a, the push rod 302a is fixed to one side of the movable column 301b, a movable groove 301a-1 is opened on the rotating column 301a, the push rod 302a is movably connected with the movable groove 301a-1, a rotating column 302b is fixed to one side of the baffle plate 203, and a force-bearing rod 302c is rotatably connected to the outer side of the rotating column 302b through a bearing, a first torsion spring 302d is fixed to one side of the force-bearing rod 302c, and the other end of the first torsion spring 302d is fixed to the rotating column 302b.

[0051] The rotating column 302b is used to drive the baffle plate 203 to rotate, and the force rod 302c is connected to the rotating column 302b through the first torsion spring 302d. When the force rod 302c rotates, the rotating column 302b can be driven to rotate by the first torsion spring 302d. When the rotating column 302b is restricted and cannot rotate, and the force rod 302c continues to rotate, the force rod 302c will apply a torsional force to the first torsion spring 302d, and the force rod 302c will not get stuck.

[0052] When the movable column 301b moves upward, it will drive the push rod 302a to move upward, and when the rotating column 301a rotates, it will drive the push rod 302a to rotate. When the push rod 302a contacts the force-bearing rod 302c, it will push the force-bearing rod 302c to rotate, so that the rotating column 302b and the baffle plate 203 can be driven to rotate through the force-bearing rod 302c, so that the catalyst can be unloaded.

[0053] The more the movable column 301b drives the push rod 302a to move upward, the closer the push rod 302a is to the top of the force-bearing rod 302c. At this time, after the push rod 302a pushes the force-bearing rod 302c to rotate, the push rod 302a will separate from the force-bearing rod 302c faster, and the opening time of the baffle plate 203 will be shorter, so that the amount of catalyst is less each time it is unloaded.

[0054] The shorter the upward stroke of the movable column 301b driving the push rod 302a, the farther the distance between the push rod 302a and the top of the force-bearing rod 302c will be. Then, after the push rod 302a pushes the force-bearing rod 302c to rotate, the push rod 302a will separate from the force-bearing rod 302c more slowly, and the opening time of the baffle plate 203 will be longer, so that the catalyst can be unloaded in larger quantity each time.

[0055] The transmission assembly 300 also includes a sensing element 303, which is arranged at the bottom end of the rotating column 301a, including a positioning plate 303a, the positioning plate 303a is fixed to the bottom end of the rotating column 301a, a fixed sleeve 303b is fixed to the bottom of the positioning plate 303a, a rotating sleeve 303c is sleeved on the outside of the fixed sleeve 303b, a second torsion spring 303d is fixed between the rotating sleeve 303c and the fixed sleeve 303b, a stirring plate 303e is fixed to one side of the rotating sleeve 303c, a second fixed shaft 303f is fixed to the inside of the rotating sleeve 303c, a second spiral groove 301b-1 is opened on the movable column 301b, and the second fixed shaft 303f slides in the second spiral groove 301b-1.

[0056] There are two positioning plates 303a, which are respectively fixed at the top and bottom of the fixed sleeve 303b. The bottom end of the movable column 301b extends into the fixed sleeve 303b and is movably connected with the fixed sleeve 303b. An arc groove is opened on the fixed sleeve 303b, and the arc groove is semicircular. The second fixed shaft 303f is movably connected with the arc groove. The second torsion spring 303d is used to connect the fixed sleeve 303b with the rotating sleeve 303c.

[0057] When the rotating column 301a rotates, it will drive the positioning plate 303a and the fixed sleeve 303b to rotate. At this time, the stirring plate 303e is located inside the oil sludge, and the oil sludge will generate resistance to the rotation of the stirring plate 303e. Therefore, when the fixed sleeve 303b rotates, the stirring plate 303e and the rotating sleeve 303c cannot rotate due to the resistance of the oil sludge. At this time, the rotation of the fixed sleeve 303b will apply a torsional force to the second torsion spring 303d. When the second torsion spring 303d is tightened to a certain angle and the elastic force of the second torsion spring 303d is greater than the resistance of the oil sludge in this state, the fixed sleeve 303b will drive the rotating sleeve 303c and the stirring plate 303e to rotate through the second torsion spring 303d.

[0058] When the fixed sleeve 303b rotates and the rotating sleeve 303c cannot rotate, the second fixed shaft 303f will slide in the second spiral groove 301b-1. The cooperation between the two can drive the movable column 301b to move upward, so that the movable column 301b can drive the connecting column 301c and the push rod 302a to move upward.

[0059] When the viscosity of the sludge is low, the resistance encountered by the stirring plate 303e is small, so the stirring plate 303e and the rotating sleeve 303c rotate at a smaller angle outside the fixed sleeve 303b, so that the movable column 301b can move upward for a shorter distance, and the spiral feeder 205 can transport less catalyst downward and discharge more catalyst each time.

[0060] When the viscosity of the sludge is high, the resistance encountered by the stirring plate 303e is relatively large. At this time, the stirring plate 303e and the rotating sleeve 303c rotate at a larger angle outside the fixed sleeve 303b, so that the movable column 301b can move upward for a longer distance, and the spiral feeder 205 can transport more catalyst downward, and the amount of catalyst discharged each time is relatively small.

[0061] Example 2

[0062] Reference Figure 1-Figure 11 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0063] Specifically, a fixed column 302e is fixed on the top of the rotating column 302b, a blocking column 302f is fixed on one side of the discharge pipe 202, a third torsion spring 302g is sleeved on the outside of the rotating column 302b, and both ends of the third torsion spring 302g are respectively fixed to the rotating column 302b and the discharge pipe 202, and the fixed column 302e cooperates with the blocking column 302f.

[0064] When the rotating column 302b rotates, it drives the fixed column 302e to rotate. When the fixed column 302e contacts the blocking column 302f, the rotating column 302b and the blocking plate 203 are restricted so that the blocking plate 203 is opened at the same angle each time.

[0065] When the push rod 302a is separated from the force-bearing rod 302c, the third torsion spring 302g can apply a torsional force to the rotating column 302b, so that the rotating column 302b can drive the material blocking plate 203 to reset, and the material blocking plate 203 can block the inside of the discharge pipe 202.

[0066] The elastic force of the third torsion spring 302g is smaller than that of the first torsion spring 302d, so that the force-bearing rod 302c can drive the rotating column 302b to rotate when rotating. Only when the rotating column 302b cannot rotate, the force-bearing rod 302c will apply a torsional force to the first torsion spring 302d.

[0067] Specifically, the transmission assembly 300 also includes a positioning member 304, which is arranged on one side of the connecting column 301c, including a support frame 304a, the support frame 304a is located on one side of the connecting column 301c, a telescopic rod 304b is fixed to the top of the support frame 304a, the top of the telescopic rod 304b is fixed to the storage tank 201, a clamping block 304c is arranged in the support frame 304a, a clamping slot 301c-1 is opened on the connecting column 301c, the clamping block 304c is engaged with the clamping slot 301c-1, a first spring 304d is fixed to one side of the clamping block 304c, and one side of the clamping block 304c is inclined.

[0068] The block 304c cooperates with the slot 301c-1 to limit the connection column 301c so that the connection column 301c does not rotate when moving upward, thereby driving the spiral feeder 205 to rotate through the cooperation of the first fixed shaft 301d and the first spiral groove 205-1.

[0069] When the connecting column 301c moves downward, the connecting column 301c is not restricted and can rotate, and the resistance of the spiral feeder 205 itself to rotation is greater than the resistance of the connecting column 301c to rotation. Therefore, when the connecting column 301c moves downward, it will drive the first fixed shaft 301d to move downward in a rotational manner, thereby preventing the spiral feeder 205 from rotating.

[0070] The first spring 304d is used to apply thrust to the block 304c so that the block 304c and the slot 301c-1 are more tightly engaged. The support frame 304a is used to support the block 304c. The telescopic rod 304b is used to support the support frame 304a so that the support frame 304a can move up and down following the connecting column 301c.

[0071] Specifically, the transmission assembly 300 also includes a limit member 305, which is arranged at the bottom of the positioning plate 303a, including a fixed frame 305a, the fixed frame 305a is fixed to the bottom of the positioning plate 303a, a positioning frame 305b is arranged in the fixed frame 305a, a limit block 305c is arranged in the positioning frame 305b, a limit hole 303c-1 is opened on the rotating sleeve 303c, the limit block 305c is engaged with the limit hole 303c-1, and a second spring 305d is fixed to one side of the limit block 305c.

[0072] One side of the limit block 305c is inclined. Through the cooperation between the limit block 305c and the limit hole 303c-1, when the rotating sleeve 303c rotates outside the fixed sleeve 303b, it is used to lock the angle of the rotating sleeve 303c, so as to avoid the angle of the rotating sleeve 303c changing during the rotation process.

[0073] The fixing frame 305a is used to support the positioning frame 305b, and the positioning frame 305b is used to support the limit block 305c. The other end of the second spring 305d is fixed to the inner wall of the positioning frame 305b. The second spring 305d is used to apply a thrust to the limit block 305c, so that the limit block 305c and the limit hole 303c-1 are more tightly engaged.

[0074] Specifically, an electric push rod 305e is disposed in the fixing frame 305a, and an output end of the electric push rod 305e is fixed to the positioning frame 305b.

[0075] The electric push rod 305e is equipped with a power supply battery. When the sludge and the catalyst are mixed and the sludge is discharged outward, the electric push rod 305e can drive the positioning frame 305b and the limit block 305c to move, so that the limit block 305c is separated from the limit hole 303c-1, thereby releasing the restriction on the rotating sleeve 303c. At this time, the second torsion spring 303d can be used to drive the rotating sleeve 303c to rotate in the opposite direction and reset. When the rotating sleeve 303c rotates in the opposite direction, the second fixed shaft 303f and the second spiral groove 301b-1 will cooperate to drive the movable column 301b to move downward and reset.

[0076] Specifically, the stirring mechanism 103 includes a rotating shaft 103-1, which is disposed in the top cover 102, a stirring paddle 103-2 is fixed to the outside of the rotating shaft 103-1, a motor 103-3 is fixed to the top of the top cover 102, and an output shaft of the motor 103-3 is fixed to the rotating shaft 103-1.

[0077] The motor 103 - 3 is used to drive the rotating shaft 103 - 1 to rotate, and the stirring paddle 103 - 2 is driven to rotate through the rotating shaft 103 - 1, so that the oil sludge can be stirred by the stirring paddle 103 - 2 and the oil sludge can be mixed with the catalyst.

[0078] Example 3

[0079] Reference Figure 1-Figure 11 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0080] Specifically, a first pulley 306 is fixed to the outer side of the rotating shaft 103 - 1 , and a second pulley 307 is fixed to the outer side of the rotating column 301 a . The first pulley 306 and the second pulley 307 are connected via a belt transmission.

[0081] The rotating shaft 103 - 1 drives the rotating column 301 a to rotate through the cooperation of the first pulley 306 and the second pulley 307 . The diameter of the second pulley 307 is larger than that of the first pulley 306 , so the rotating column 301 a can rotate at a slower speed.

[0082] Specifically, there are multiple slots 301c-1, which are evenly distributed in a ring shape on the outside of the connecting column 301c.

[0083] By providing a plurality of slots 301c - 1 , the block 304c can be engaged with the slot 301c - 1 when the connecting column 301c is rotated to any angle.

[0084] Specifically, there are two stirring plates 303e, which are respectively fixed on both sides of the rotating sleeve 303c.

[0085] By providing two stirring plates 303e, the falling catalyst can be initially stirred, so that the catalyst can be quickly mixed with the oil sludge.

[0086] Specifically, there are multiple limiting holes 303c-1, which are evenly distributed in a ring shape on the outer side of the rotating sleeve 303c.

[0087] By providing a plurality of limiting holes 303c - 1 , the limiting blocks 305c can be engaged with the limiting holes 303c - 1 after the rotating sleeve 303c is rotated to any angle.

[0088] In summary, the sludge carbonization pre-catalyst mixing device has the following advantages:

[0089] 1. It can automatically add catalyst to the sludge during the mixing process;

[0090] Second, it can automatically adjust the amount of catalyst added according to the viscosity of the sludge. If the sludge viscosity is too high, more catalyst will be added, and if the sludge viscosity is low, less catalyst will be added;

[0091] 3. When the viscosity of the sludge is too high, the catalyst can be added in small amounts and multiple times, so that the catalyst can be gradually dispersed in different positions, increasing the chance of contact with the sludge and improving mixing uniformity;

[0092] 4. When the sludge viscosity is low, the catalyst can be added in small amounts to improve work efficiency.

[0093] During use, after a specified amount of sludge is injected into the tank body 101, the motor 103-3 is started to drive the rotating shaft 103-1 and the stirring paddle 103-2 to rotate, so that the stirring paddle 103-2 stirs the sludge, and in the early stirring process, the rotation speed of the rotating shaft 103-1 is slow, thereby avoiding the generation of dust from the catalyst during the addition of the catalyst.

[0094] When the rotating shaft 103-1 rotates, it will drive the rotating column 302b to rotate. When the rotating column 301a rotates, it will drive the positioning plate 303a and the fixed sleeve 303b to rotate. At this time, the stirring plate 303e is located inside the oil sludge, and the oil sludge will produce resistance to the rotation of the stirring plate 303e. Therefore, when the fixed sleeve 303b rotates, the stirring plate 303e and the rotating sleeve 303c cannot rotate due to the resistance of the oil sludge. At this time, the rotation of the fixed sleeve 303b will apply a torsional force to the second torsion spring 303d. When the second torsion spring 303d is tightened to a certain angle, and in this state, the elastic force of the second torsion spring 303d is greater than the resistance of the oil sludge, the fixed sleeve 303b will drive the rotating sleeve 303c and the stirring plate 303e to rotate through the second torsion spring 303d.

[0095] When the fixed sleeve 303b rotates and the rotating sleeve 303c cannot rotate, the second fixed shaft 303f will slide in the second spiral groove 301b-1. The cooperation between the two can drive the movable column 301b to move upward, so that the movable column 301b can drive the connecting column 301c and the push rod 302a to move upward.

[0096] When the viscosity of the sludge is low, the resistance encountered by the stirring plate 303e is small, so the stirring plate 303e and the rotating sleeve 303c rotate at a smaller angle outside the fixed sleeve 303b, thereby allowing the movable column 301b to move upward a smaller stroke. When the viscosity of the sludge is high, the resistance encountered by the stirring plate 303e is large. At this time, the stirring plate 303e and the rotating sleeve 303c rotate at a larger angle outside the fixed sleeve 303b, thereby allowing the movable column 301b to move upward a larger stroke.

[0097] When the movable column 301b moves upward, it will drive the connecting column 301c to move upward, and drive the first fixed shaft 301d to slide in the first spiral groove 205-1 through the connecting column 301c. Through the cooperation of the two, the spiral feeder 205 can be driven to rotate, so that the catalyst above the partition plate 204 can be transported to the bottom of the partition plate 204 through the spiral feeder 205.

[0098] The more the movable column 301b moves upward, the more turns the spiral feeder 205 rotates, and the more catalyst is transported downward. Conversely, the less the movable column 301b moves upward, the fewer turns the spiral feeder 205 rotates, and the less catalyst is transported downward.

[0099] When the movable column 301b moves upward, it will drive the push rod 302a to move upward, and when the rotating column 301a rotates, it will drive the push rod 302a to rotate. When the push rod 302a contacts the force-bearing rod 302c, it will push the force-bearing rod 302c to rotate, so that the rotating column 302b and the baffle plate 203 can be driven to rotate through the force-bearing rod 302c, so that the catalyst can be unloaded.

[0100] The more the movable column 301b drives the push rod 302a to move upward, the closer the push rod 302a is to the top of the force-bearing rod 302c. At this time, after the push rod 302a pushes the force-bearing rod 302c to rotate, the push rod 302a will separate from the force-bearing rod 302c faster, and the opening time of the baffle plate 203 will be shorter, so that the amount of catalyst is less each time it is unloaded.

[0101] The shorter the upward stroke of the movable column 301b driving the push rod 302a, the farther the distance between the push rod 302a and the top of the force-bearing rod 302c will be. Then, after the push rod 302a pushes the force-bearing rod 302c to rotate, the push rod 302a will separate from the force-bearing rod 302c more slowly, and the opening time of the baffle plate 203 will be longer, so that the catalyst can be unloaded in larger quantity each time.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
