Description

Technical Field

[0001] The present invention relates to the technical field of reactors, in particular to a reactor and a production process for producing a degreasing agent. Background Art

[0002] Before metal chemical treatment, electroplating, and coating, a degreaser is often required to ensure optimal processing results. During the degreaser production process, the raw materials are placed into a reactor and then stirred with an agitator to ensure uniform mixing. Reactors are typically equipped with manholes, which are sealed with manhole covers to facilitate inspection and maintenance within the reactor.

[0003] For example, patent publication CN219615546U discloses a self-cleaning reactor with a conical lid and a hinged manhole cover. The hinged joint of the manhole cover is typically equipped with a torsion spring to facilitate its opening. However, the tilted manhole cover increases its rotational resistance under the influence of its own gravity, thereby affecting its opening and closing speed. Summary of the Invention

[0004] Based on this, it is necessary to provide a reactor and production process for degreasing agent production to address the technical problem that the current tilt setting of the manhole cover affects the opening and closing speed.

[0005] The above purpose is achieved through the following technical solutions:

[0006] A reactor for producing a degreaser comprises a reactor body, the reactor body having a conical surface, an opening being provided on the conical surface, a mounting ring being provided at the opening, the axis of the mounting ring extending in the up-down direction, a manhole cover being provided on the mounting ring, the manhole cover comprising a hinged ring, the hinged ring being coaxially rotatably arranged on the mounting ring, the hinged ring being hingedly connected to an upper manhole cover by a hinged shaft, the hinged shaft being provided with a torsion spring, the torsion spring having a tendency to move the upper manhole cover away from the hinged ring; a lower manhole cover being provided inside the hinged ring, the lower manhole cover being coaxially rotatably arranged on the mounting ring, the mounting ring being further provided with a locking member, the locking member being used to lock the upper manhole cover above the hinged ring so that the upper manhole cover and the lower manhole cover can correspond to each other up and down, thereby sealing the opening.

[0007] Furthermore, a sealing ring is provided on the upper surface of the lower cover of the manhole cover, and the opening is located inside the sealing ring. A transmission mechanism is provided between the lower cover of the manhole cover and the hinge ring, and the transmission mechanism drives the lower cover of the manhole cover to rotate differentially when the hinge rotates circumferentially around the mounting ring.

[0008] Furthermore, the sealing ring is formed by a plurality of interconnected sealing parts, each sealing part includes a straight segment and an arc segment, the straight segment has a first end and a second end, the first end is arranged close to the opening relative to the second end, the arc segment is located on the second end, and the arc segment is connected to the first end of the adjacent sealing part.

[0009] Furthermore, a plurality of drainage holes are provided on the lower cover of the manhole cover, and each drainage hole corresponds to the inside of each arc segment.

[0010] Furthermore, the upper surface of the lower cover of the manhole cover is provided with a plurality of arc-shaped grooves evenly distributed around its circumference, and the axes of the arc-shaped grooves extend radially along the lower cover of the manhole cover. The lower surface of the upper cover of the manhole cover is provided with a plurality of arc-shaped protrusions evenly distributed around its circumference, and the axes of the arc-shaped protrusions extend radially along the upper cover of the manhole cover. The arc-shaped protrusions correspond one to one with the arc-shaped grooves up and down, and the arc-shaped protrusions and the arc-shaped grooves can rotate relative to each other.

[0011] Furthermore, the transmission mechanism is a planetary gear mechanism, the inner circumference of the hinged ring is provided with an inner gear ring for unidirectional rotation, the inner gear ring has an inner gear ring, the outer circumference of the mounting ring is provided with an outer gear ring, a planet carrier is provided between the inner gear ring and the outer gear ring, a first planetary gear and a second planetary gear are rotatably provided on the planet carrier, the second planetary gear is fixed above the first planetary gear, the first planetary gear is meshed with the inner gear ring, and the second planetary gear is meshed with the outer gear ring, the lower cover of the manhole cover is fixedly connected to the planet carrier, the rotation of the hinged ring drives the planet carrier differentially through the first planetary gear and the second planetary gear, and the planet carrier drives the lower cover of the manhole cover to rotate synchronously.

[0012] Furthermore, an annular step is provided on the mounting ring, and a compression spring is provided between the planet carrier and the annular step. The compression spring has a tendency to move the planet carrier upward, so that the planet carrier drives the lower cover of the manhole cover to extend upward from the hinged ring.

[0013] Furthermore, a plurality of first rollers and second rollers are provided at intervals on the outer periphery of the mounting ring. Both the first rollers and the second rollers extend in the up and down directions and can rotate around their own axes. The first roller is located above the second roller. The lower cover of the manhole cover is rotatably set on the mounting ring through the first rollers, and the hinged ring is rotatably set on the mounting ring through the second rollers.

[0014] Furthermore, the locking part includes a locking ring, which is fixedly arranged on the mounting ring, and a plurality of rotating rods are hinged in the circumferential direction of the locking ring, and the rotating rod can rotate around a horizontal axis. A sliding sleeve is provided on the rotating rod, and a pressure plate is provided on the slider, and the pressure plate is used to press the manhole cover. The internal anti-rotation assembly of the slider is provided with a locking nut, and the internal thread of the locking nut is connected to a screw, which is rotatably connected to the rotating rod, and a driving handle is provided on the screw. By rotating the driving handle, the locking nut moves along the screw and drives the slider to slide along the rotating rod, so that the pressure plate can press the manhole cover onto the hinged ring.

[0015] A degreasing agent production process, using the above-mentioned reactor for degreasing agent production, comprises the following steps:

[0016] S1. Put the raw materials used for the production of the degreasing agent into the kettle and stir;

[0017] S2. Control the locking piece to unlock the manhole cover from the hinge ring, and pull the manhole cover to rotate so that the hinge axis is at the lowest position of the mounting ring;

[0018] S3. Observe the reaction of the raw materials in the reactor through the opening;

[0019] S4. Pull the manhole cover cover again to rotate it so that the hinge shaft is at the uppermost position of the mounting ring, and control the locking piece to lock the manhole cover cover on the hinge ring again.

[0020] The beneficial effects of the present invention are:

[0021] The present invention provides a reactor and production process for producing degreasers. First, before opening the manhole cover, the locking member is controlled to unlock the upper cover of the manhole cover from the hinge ring, and then the upper cover of the manhole cover is rotated to drive the hinge shaft to rotate to the lowest position of the mounting ring. In this way, under the combined action of gravity and the torsion spring, the upper cover of the manhole cover is more easily separated from the lower cover of the manhole cover, thereby saving more effort in the process of opening the cover. Before closing the manhole cover, the upper cover of the manhole cover is first pulled to rotate so that the hinge shaft is at the highest position of the mounting ring. Under the action of gravity, the upper cover of the manhole cover is more easily close to the lower cover of the manhole cover. Then, the locking member is controlled to re-lock the upper cover of the manhole cover on the hinge ring. It can be seen that by rotating the manhole cover and setting it on the reactor body, gravity can be used to make the opening and closing of the manhole cover more labor-saving.

[0022] Second, the rotation of the upper cover of the manhole cover drives the hinged ring to rotate synchronously, and the hinged ring drives the lower cover of the manhole cover to rotate differentially, so that the sealing ring can rotate relative to the upper cover of the manhole cover, thereby preventing a certain position of the sealing ring from being subjected to high pressure or corrosion for a long time, which helps to extend the service life of the sealing ring.

[0023] Third, when the sealing ring rotates relative to the manhole cover, the straight section can scrape off the raw materials attached to the bottom surface of the manhole cover, and collect the scraped raw materials in the arc section, and then return them to the interior of the kettle through the drainage hole, promoting uniform mixing of the raw materials.

[0024] Fourth, when the upper cover of the manhole cover rotates relative to the lower cover of the manhole cover, the arc-shaped protrusion and the arc-shaped groove cooperate to make the upper cover of the manhole cover vibrate back and forth relative to the lower cover of the manhole cover, thereby promoting the flowable raw materials attached to the upper cover of the manhole cover to fall off and improve the mixing effect.

[0042] like Figures 1 to 12As shown, an embodiment of the present invention provides a reactor for producing a degreasing agent, comprising a reactor body 101 having a conical surface with an opening. A mounting ring 102 is provided at the opening, with the axis of the mounting ring 102 extending in the vertical direction. Specifically, the mounting ring 102 is welded to the conical surface. A stirring motor 103 is provided on the reactor body 101 for stirring the raw materials used in the production of the degreasing agent.

[0043] A manhole cover is provided on the mounting ring 102, and the manhole cover includes a hinge ring 202, which is coaxially rotatably arranged on the mounting ring 102, and the hinge ring 202 is hinged to the manhole cover upper cover 201 through a hinge shaft, and the hinge shaft is provided with a torsion spring (not shown in the figure), which has a tendency to make the manhole cover upper cover 201 move away from the hinge ring 202, so as to facilitate the automatic opening of the manhole cover upper cover 201; a manhole cover lower cover 203 is provided inside the hinge ring 202, and the manhole cover lower cover 203 is coaxially rotatably arranged on the mounting ring 102, and a locking member is further provided on the mounting ring 102, and the locking member is used to lock the manhole cover upper cover 201 above the hinge ring 202, so that the manhole cover upper cover 201 and the manhole cover lower cover 203 can correspond to each other up and down, thereby sealing the opening. Specifically, the hinge ring 202 and the manhole cover upper cover 201 are both provided with connecting ears, and the connecting ears are hinged through a hinge shaft.

[0044] In this way, before opening the manhole cover, the locking member is first controlled to unlock the manhole cover upper cover 201 from the hinge ring 202, and then the manhole cover upper cover 201 is rotated to drive the hinge shaft to rotate to the lowest position of the mounting ring 102. In this way, under the combined action of gravity and the torsion spring, the manhole cover upper cover 201 is more easily separated from the manhole cover lower cover 203, thereby saving more effort in the cover opening process; before closing the manhole cover, the manhole cover upper cover 201 is first pulled to rotate so that the hinge shaft is at the highest position of the mounting ring 102. Under the action of gravity, the manhole cover upper cover 201 is more easily close to the manhole cover lower cover 203, and then the locking member is controlled to re-lock the manhole cover upper cover 201 on the hinge ring 202. It can be seen from this that by rotating the manhole cover on the kettle body 101, gravity can be used to make the opening and closing of the manhole cover more labor-saving.

[0045] like Figures 6 and 7As shown, a sealing ring 204 is provided on the upper surface of the manhole cover lower cover 203, and the opening is located within the sealing ring 204. A transmission mechanism is provided between the manhole cover lower cover 203 and the hinged ring 202. The transmission mechanism causes the hinged ring 202 to rotate differentially when it rotates around the mounting ring 102. Because the hinged ring 202 is hingedly connected to the manhole cover upper cover 201, the manhole cover upper cover 201 and the hinged ring 202 rotate synchronously. The rotation of the manhole cover upper cover 201 drives the hinged ring 202 to rotate synchronously, and the hinged ring 202 drives the manhole cover lower cover 203 to rotate differentially, allowing the sealing ring 204 to rotate relative to the manhole cover upper cover 201. This prevents a certain position of the sealing ring 204 from being subjected to excessive pressure or corrosion for a long time, helping to extend the service life of the sealing ring 204.

[0046] Furthermore, the sealing ring 204 is formed by a plurality of interconnected sealing portions, each of which includes a straight segment 2042 and an arcuate segment 2041. The straight segment 2042 has a first end and a second end, with the first end positioned relative to the second end and closer to the opening. The arcuate segment 2041 is located on the second end and connects to the first end of an adjacent sealing portion. Six groups of sealing portions are provided, each with a central angle of 60°.

[0047] When the sealing ring 204 rotates relative to the manhole cover 201, the straight section 2042 can scrape the raw materials adhering to the bottom surface of the manhole cover 201 and collect the scraped raw materials in the arc section 2041. To ensure the scraping effect, the horizontal surfaces of the straight section 2042 and the arc section 2041 are both arcuate surfaces.

[0048] Furthermore, the manhole cover lower cover 203 is provided with a plurality of drainage holes 2032, each drainage hole 2032 corresponding to the interior of each arc segment 2041. In this way, the liquid in the arc segment 2041 can flow back to the interior of the kettle body 101 through the drainage holes 2032, promoting uniform mixing of the raw materials.

[0049] Furthermore, the upper surface of the manhole cover lower cover 203 is provided with a plurality of arc-shaped grooves 2031 evenly distributed around its circumference, and the axis of the arc-shaped grooves 2031 extends radially along the manhole cover lower cover 203. The lower surface of the manhole cover upper cover 201 is provided with a plurality of arc-shaped protrusions 2011 evenly distributed around its circumference, and the axis of the arc-shaped protrusions 2011 extends radially along the manhole cover upper cover 201. The arc-shaped protrusions 2011 correspond one to one with the arc-shaped grooves 2031, and the arc-shaped protrusions 2011 and the arc-shaped grooves 2031 can rotate relative to each other.

[0050] In this way, when the manhole cover upper cover 201 rotates relative to the manhole cover lower cover 203, the arc-shaped protrusion 2011 cooperates with the arc-shaped groove 2031 to make the manhole cover upper cover 201 vibrate back and forth relative to the manhole cover lower cover 203, thereby promoting the falling of the fluid raw materials attached to the manhole cover upper cover 201 and improving the mixing effect.

[0051] Furthermore, the transmission mechanism is a planetary gear mechanism, and the inner circumference of the hinge ring 202 is provided with an inner gear ring 301 for unidirectional rotation. Figure 9 As shown, the inner circumference of the hinge ring 202 is hinged with a pawl 2021, and a return spring is provided between the pawl 2021 and the hinge ring 202. The outer circumference of the inner gear ring 301 is provided with a ratchet 3011, and the ratchet 3011 slides in conjunction with the pawl 2021, so that the hinge ring 202 can only rotate counterclockwise (when viewed toward the paper) relative to the inner gear ring 301.

[0052] like Figures 9 to 12 As shown, the inner gear ring 301 has an inner gear ring, the outer gear ring 302 is provided on the outer periphery of the mounting ring 102, and a planet carrier 303 is provided between the inner gear ring and the outer gear ring 302. The planet carrier 303 is rotatably provided with a first planetary gear 3031 and a second planetary gear 3032. The second planetary gear 3032 is fixed above the first planetary gear 3031. The first planetary gear 3031 meshes with the inner gear ring, and the second planetary gear 3032 meshes with the outer gear ring 302. The manhole cover lower cover 203 is fixedly connected to the planet carrier 303. The rotation of the hinged ring 202 drives the planet carrier 303 via the first planetary gear 3031 and the second planetary gear 3032, which in turn drives the manhole cover lower cover 203 to rotate synchronously. The provision of the first planetary gear 3031 and the second planetary gear 3032 can make the size of the inner gear ring 301 more reasonable, thereby reducing the overall size of the manhole cover. In other embodiments, only the first planetary gear 3031 may be provided, and the first planetary gear 3031 is meshed with both the inner gear ring and the outer gear ring 302 .

[0053] The inner gear ring and the outer gear ring 302 have a certain length in the vertical direction, so that the first planetary gear 3031 can slide up and down a certain distance along the inner gear ring, and the second planetary gear 3032 can slide up and down a certain distance along the outer gear ring 302.

[0054] The transmission ratio of the hinge ring 202 to the manhole cover lower cover 203 is 3: 2. In this way, the hinge ring 202 rotates 90 degrees to rotate the manhole cover lower cover 203 by 60 degrees, so that the sealing ring 204 on the manhole cover lower cover 203 coincides with the position before the rotation.

[0055] Furthermore, an annular step is provided on the mounting ring 102, and a compression spring 208 is provided between the planet carrier 303 and the annular step. The compression spring 208 has a tendency to move the planet carrier 303 upward, thereby causing the planet carrier 303 to drive the manhole cover lower cover 203 to extend upward from the hinge ring 202. When the manhole cover upper cover 201 is pressed onto the hinge ring 202, the manhole cover lower cover 203 is pressed down into the hinge ring 202.

[0056] Since a sealing gasket is provided between the lower cover 203 of the manhole cover and the mounting ring 102, the upward extension of the lower cover 203 of the manhole cover can reduce the friction between the lower cover 203 of the manhole cover and the mounting ring 102, thereby facilitating the rotation of the lower cover 203 of the manhole cover. After the lower cover 203 of the manhole cover is pressed and re-enters the interior of the hinged ring 202, a seal can be re-formed, thereby improving the sealing effect.

[0057] Furthermore, a plurality of first rollers 304 and second rollers 305 are provided at intervals on the outer periphery of the mounting ring 102. The first rollers 304 and the second rollers 305 both extend in the up and down directions and can rotate around their own axes. The first rollers 304 are located above the second rollers 305. The lower cover 203 of the manhole cover is rotatably set on the mounting ring 102 through the first rollers 304, and the hinged ring 202 is rotatably set on the mounting ring 102 through the second rollers 305.

[0058] Furthermore, the locking member includes a locking ring 205, which is fixed on the mounting ring 102 by a clamp, and a plurality of rotating rods 206 are hinged on the circumference of the locking ring 205, and the rotating rod 206 can rotate around a horizontal axis. A slider 207 is provided on the sliding sleeve of the rotating rod 206, and a pressure plate is provided on the slider 207. The pressure plate is used to press the manhole cover 201. The internal anti-rotation assembly of the slider 207 is provided with a locking nut, and the internal thread of the locking nut is connected to a screw, which is rotatably connected to the rotating rod 206. A driving handle is provided on the screw, and the locking nut is moved along the screw by rotating the driving handle to drive the slider 207 to slide along the rotating rod 206, so that the pressure plate can press the manhole cover 201 onto the hinged ring 202.

[0059] When it is necessary to lock the manhole cover 201 on the hinge ring 202, the rotating rod 206 is first rotated to bring the pressure plate closer to the manhole cover 201, and then the driving handle is rotated to move the locking nut along the screw rod and drive the slider 207 to slide along the rotating rod 206, so that the pressure plate can press the manhole cover 201 against the hinge ring 202. When it is necessary to unlock the manhole cover 201 from the hinge ring 202, the handle is first driven to make the pressure plate no longer press the manhole cover 201, and then the rotating rod 206 is rotated to move the rotating rod 206 away from the manhole cover 201.

[0060] In other embodiments, locking members of other structures in the prior art may be selected, such as the rotating rod 206 having only a knob threadedly connected thereto, and the knob engaging with a locking ring on the manhole cover upper cover 201 for blocking.

[0061] In combination with the above embodiments, the use principle and working process of the embodiments of the present invention are as follows:

[0062] In the initial state, the manhole cover is as follows Figure 3 The first state shown is that the hinge axis corresponds to the upper left position of the mounting ring 102, and the manhole cover is in a closed state.

[0063] When the manhole cover needs to be opened, the locking member is first controlled to unlock the manhole cover upper cover 201 from the hinge ring 202. At this time, the manhole cover upper cover 201 is still tightly attached to the hinge ring 202 under the action of gravity. Then the manhole cover upper cover 201 is rotated counterclockwise to the lowest position of the mounting ring 102, and then the manhole cover upper cover 201 is pulled open to the maximum opening and closing angle, that is, Figure 4 The second state shown in FIG. Because the gravity of the manhole cover makes it easier to open under the action of the torsion spring, the cover opening operation is more labor-saving.

[0064] During the counterclockwise rotation of the manhole cover upper cover 201, specifically, the manhole cover upper cover 201 is first rotated 45° counterclockwise, the manhole cover upper cover 201 drives the hinged ring 202 to rotate counterclockwise synchronously, and the hinged ring 202 rotates the manhole cover lower cover 203 counterclockwise by 30° through the transmission mechanism, that is, the manhole cover lower cover 203 rotates clockwise relative to the manhole cover upper cover 201, so that the sealing ring 204 can scrape a part of the raw materials attached to the bottom of the manhole cover upper cover 201 to the inside of the arc section 2041, and the liquid therein directly flows back to the inside of the kettle body 101 through the drainage hole 2032. Then lift the manhole cover upper cover 201 upward and rotate it counterclockwise about 5° and then put it down, so that the sticky material adhered to the manhole cover upper cover 201 corresponds to the outer periphery of the sealing ring 204, and then continue to rotate the manhole cover upper cover 201 counterclockwise. At this time, the sticky material will be pushed to the outermost side of the manhole cover lower cover 203 by the sealing ring 204, which is convenient for manual cleaning until the manhole cover upper cover 201 rotates to the lowest position of the hinge shaft corresponding to the mounting ring 102.

[0065] When the manhole cover needs to be closed, the manhole cover upper cover 201 is rotated counterclockwise again so that the hinge shaft corresponds to the uppermost position of the mounting ring 102. At this time, the manhole cover is as shown in FIG. Figure 5 In the third state shown, under the action of gravity, the upper cover 201 of the manhole cover automatically approaches the lower cover 203 of the manhole cover. Then, manually press down to make the upper cover 201 close to the hinge ring 202, and control the locking member to re-lock the upper cover 201 on the hinge ring 202. In this way, gravity overcomes part of the elastic force of the torsion spring, making the closing of the manhole cover more labor-saving.

[0066] In addition, in order to facilitate force balance when the manhole cover rotates, a counterweight block can be set at a position on the other side of the manhole cover lower cover 203 corresponding to the hinge axis.

[0067] A degreasing agent production process, using the reactor for degreasing agent production in the above embodiment, comprises the following steps:

[0068] S1. Put the raw materials used for the production of the degreasing agent into the kettle 101 and stir;

[0069] S2. Control the locking member to unlock the manhole cover upper cover 201 from the hinge ring 202, and pull the manhole cover upper cover 201 to rotate so that the hinge axis is at the lowest position of the mounting ring 102;

[0070] S3. Observe the reaction of the raw materials in the reactor through the opening;

[0071] S4. Pull the manhole cover upper cover 201 again to rotate so that the hinge shaft is at the uppermost position of the mounting ring 102, and control the locking member to lock the manhole cover upper cover 201 on the hinge ring 202 again.

[0072] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
