Description

Technical Field

[0001] The utility model relates to the technical field of carbon black production, in particular to a pressure regulating device for carbon black smoke. Background Art

[0002] Carbon black is a fine powder produced by incomplete combustion of carbon-containing raw materials, mainly petroleum. Carbon black has a wide range of uses and is currently the best quality and cheapest black pigment. It has a certain degree of conductivity and is also a commonly used reinforcing agent in the rubber industry. The appearance of carbon black is pure black fine particles or powder. The fineness of the particles, the size of the specific gravity and other physical properties vary with the raw materials used and the preparation process. However, no matter what kind of carbon black preparation process is inseparable from the participation of gas phase substances, so the pressure parameters of gas phase substances such as carbon black smoke must be controlled.

[0003] According to Chinese patent publication number CN219655276U, a carbon black flue gas pressure regulating device includes a driving unit and a pressure regulating unit, wherein the driving unit and the pressure regulating unit are connected via a bracket; the driving unit is arranged on one side of the flue, and includes a pneumatic actuator and a driving mechanism connected to the pneumatic actuator; the pressure regulating unit includes a cover mechanism and a supporting mechanism, wherein the driving mechanism is connected to the cover mechanism via the supporting mechanism to control the opening of the cover mechanism.

[0004] This patent number sets a pneumatic actuator to receive DCS signals to control the rotation of the drive shaft. The drive shaft drives the transmission arm, the connecting piece, the valve plate arm and the valve plate to start moving. When the connecting piece is tightened, the valve plate opening increases; when the connecting piece is loosened, the valve plate is closed due to its own gravity and the tension of the elastic piece. When the production is abnormal and the flue gas pressure is too high, the flue gas will push the valve plate upward to achieve the function of automatic pressure relief. When the valve plate is lifted up, since the connecting piece is made of rope, the length of the connecting rope remains unchanged when the pneumatic actuator is not in use. Therefore, after the valve plate is lifted up, the angle changes and the connecting rope will easily pile up, resulting in entanglement during the automatic opening and closing of the valve plate, thereby affecting the normal opening of the valve plate. Therefore, a carbon black flue gas pressure regulating device is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a carbon black flue gas pressure regulating device, which has the advantages of preventing the connecting rope from being entangled during the automatic opening and closing of the valve plate, and solves the problem that the connecting rope will easily pile up when the angle of the valve plate changes after being lifted up, causing entanglement during the automatic opening and closing of the valve plate.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a carbon black flue gas pressure regulating device, comprising a flue, a traction mechanism is installed on the right side of the flue, a support frame is fixedly connected to the right side of the flue, a valve plate is placed on the top of the flue, a connecting plate is fixedly connected to the right side of the valve plate, and the connecting plate is rotatably connected to the inside of the support frame.

[0007] The traction mechanism includes a support plate, which is fixed on the side wall of the flue, a drive motor is fixedly installed on the top of the support plate, a take-up drum is fixedly connected to the output shaft of the drive motor, a connecting rope is fixedly wound around the outside of the take-up drum, an end of the connecting rope away from the take-up drum is fixedly connected to a ring, a third counterweight is fixedly installed on the outside of the connecting rope, a second counterweight is slidably connected to the outside of the connecting rope, and the ring is sleeved on the outside of a fixed rod fixed to the inside of the connecting plate.

[0008] Furthermore, a fixing plate is fixedly connected to the top of the valve plate, a sliding groove is provided on the side wall of the fixing plate, a sliding block is slidably connected inside the sliding groove, and a first counterweight block is detachably mounted on the sliding block.

[0009] Furthermore, a sealing gasket is fixed to the bottom of the valve plate, and the diameter of the valve plate is larger than the diameter of the flue.

[0010] Furthermore, a through opening is provided on the left side inside the support plate, and a through hole is provided on the right side inside the support plate.

[0011] Furthermore, a first wire wheel is installed on both the left and right inner side walls of the through hole, and a second wire wheel is installed on the bottom of the support plate.

[0012] Furthermore, the connecting rope passes through the through-port and the through-hole in sequence and extends to the outside, and the second wire wheel is located on the right side of the bottom of the through-port.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The carbon black flue gas pressure regulating device, when the pressure in the flue is too high, pushes the valve plate to open for pressure relief. Since the ring sleeve is mounted on the fixed rod and cooperates with the second counterweight block and the third counterweight block, the connecting rope can always be kept in a vertical downward state, and the connecting rope forms a U shape, thereby preventing the cables from being stacked together, thereby preventing the valve plate from being entangled during the automatic opening and closing process.

[0021] It is worth mentioning that an elastic connecting strip detachably connected to the valve plate 2 is installed on the side wall of the flue 1, so as to prevent the valve plate 2 from being over-opened due to excessive pressure.

[0022] The traction mechanism includes a support plate 11, which is fixed on the side wall of the flue 1. A drive motor 9 is fixedly installed on the top of the support plate 11. A take-up drum 8 is fixedly connected to the output shaft of the drive motor 9. A connecting rope 19 is wrapped around and fixed on the outside of the take-up drum 8. An end of the connecting rope 19 away from the take-up drum 8 is fixedly connected to a ring sleeve 16. A third counterweight block 18 is fixedly installed on the outside of the connecting rope 19. The outside of the connecting rope 19 is slidably connected to the second counterweight block 13. The ring sleeve 16 is sleeved on the outside of a fixed rod 17 fixed to the inside of the connecting plate 7.

[0023] It is worth mentioning that a stabilizing plate is installed on the top of the support plate 11, and the take-up reel 8 is rotatably connected to the stabilizing plate via a rotating shaft.

[0024] In this embodiment, a fixing plate 3 is fixedly connected to the top of the valve plate 2, a sliding groove 4 is provided on the side wall of the fixing plate 3, a sliding block 5 is slidingly connected inside the sliding groove 4, and a first counterweight 6 is detachably mounted on the sliding block 5.

[0025] It should be noted that the first counterweight 6 is fixed to the slider 5 by bolts, so that it is convenient to replace the first counterweight 6 of different models.

[0026] A sealing gasket is fixed to the bottom of the valve plate 2 , and the diameter of the valve plate 2 is larger than the diameter of the flue 1 .

[0027] The sealing performance between the valve plate 2 and the flue 1 is increased by providing a sealing gasket.

[0028] See also Figure 1 , Figure 2 A through opening 15 is opened on the left side of the support plate 11, a through hole 12 is opened on the right side of the support plate 11, a first wire wheel 10 is installed on the left and right inner walls of the through hole 12, a second wire wheel 14 is installed at the bottom of the support plate 11, a connecting rope 19 passes through the through opening 15 and the through hole 12 in sequence and extends to the outside, and the second wire wheel 14 is located on the right side of the bottom of the through opening 15.

[0029] It should be noted that, by sleeved on the fixed rod 17, and in cooperation with the second counterweight block 13 and the third counterweight block 18, the connecting rope 19 can be kept in a vertical downward position when the valve plate 2 is opened, and the connecting rope 19 forms a U-shape, thereby preventing the valve plate 2 opening cables from stacking together during automatic pressure relief, thereby avoiding possible entanglement during the automatic opening and closing process of the valve plate 2.

[0030] The working principle of the above embodiment is as follows: when in use, the motor 9 needs to be driven to drive the take-up drum 8 to rotate, so that the connecting rope 19 can be wound on the take-up drum 8. When the connecting rope 19 is in a stretched state, the valve plate 2 can be pulled to open. By pulling the valve plate 2 to rotate, the valve plate 2 can be opened to change the opening and closing angle, thereby realizing the regulation of the flue gas pressure. The valve plate 2 can be closed by reverse rotation to loosen the connecting rope 19. If the flue gas pressure in the flue 1 is too large to push the valve plate 2 to open, the slider 5 will slide in the slide groove 4, thereby moving the first counterweight 6 to the right. Since the ring sleeve 16 is sleeved on the fixed rod 17, and cooperates with the second counterweight 13 and the third counterweight 18, the connecting rope 19 can be kept in a vertical downward state, and the connecting rope 19 forms a U-shape, thereby avoiding the cables from being stacked together, thereby avoiding the possibility of the connecting rope 19 being entangled during the automatic opening and closing of the valve plate 2.
