Description

Technical Field

[0001] The invention relates to the technical field of carbon black raw material injection equipment, in particular to a raw material oil gun head with optimized carbon black structure. Background Art

[0002] As a key functional filler, carbon black is widely used in rubber, plastic, coating and battery industries. Its structural characteristics directly affect the performance of the product. At present, the production process of carbon black is to insert the raw oil gun into the reactor from the front end of the reactor, and then spray the raw oil through the raw oil gun. The raw oil reacts in the reactor at high temperature to generate carbon black.

[0003] A Chinese patent discloses a raw material oil gun nozzle for soft carbon black (authorization announcement number CN217527874U). Since the above-mentioned device covers the filter element on the liquid inlet end of the nozzle, although this can filter out impurities in the crude oil passing through, since the filter element is laid flat on the inner side of the nozzle, the crude oil will vertically impact the filter element during the process of passing through the filter element, which will increase the filtering burden of the filter element. Moreover, as the impurities filtered by the filter element gradually increase, the resistance of the crude oil passing through the filter element will not only increase, but also increase the impact force of the crude oil on the filter element, making it difficult to ensure that the filter element can operate for a long time. Summary of the invention

[0004] Based on this, it is necessary to provide a raw oil gun head with optimized carbon black structure to address the problem that the filter in the raw oil gun head with anti-clogging for carbon black production is prone to accumulate impurities, increasing the burden of crude oil passing and the probability of filter damage.

[0005] A raw oil gun head with optimized carbon black structure comprises an atomizing nozzle, one end of which is fixedly connected and communicated with an air pipe, and the other end of which is installed with a bolt, the rod of which passes through the outside of the atomizing nozzle, the rod of which is threadedly connected with an oil pipe arranged inside the air pipe, and the rod of the bolt is sleeved with a guiding and filtering mechanism arranged between the air pipe and the oil pipe.

[0006] Furthermore, the guiding and filtering mechanism includes a rotating seat which is sleeved on the bolt rod and arranged between the air pipe and the oil pipe, the surface of the rotating seat is rotatably connected to a ring frame, the inner side of the ring frame is provided with two ring openings which are respectively connected to the inlet of the atomizing nozzle and the outlet of the oil pipe, a stainless steel filter mesh ring is fixedly connected to the inner side of the ring opening connected to the inlet of the atomizing nozzle, a spiral plate distributed in a ring shape is fixedly connected to the inside of the ring frame, and one end of the ring frame is provided with an air inlet distributed in a ring shape.

[0007] In one of the embodiments, the flow force of crude oil and high-pressure air is used to actively rotate the ring frame and the stainless steel filter mesh ring, which can not only throw solid impurities away from the stainless steel filter mesh ring under the action of rotating centrifugal force, but also solve the problem that the filter element in the existing crude oil gun head with anti-clogging for carbon black production is prone to accumulate impurities, increasing the burden of crude oil passing through and the probability of filter element damage.

[0008] Furthermore, the surface of the spiral plate is provided with evenly distributed vertical holes, and the guiding and filtering mechanism also includes a blocking component, which includes an annular blocking plate and a blocking ring. The annular blocking plate is arranged between the rotating seat and the stainless steel filter mesh ring, and one end of the annular blocking plate is provided with an arc hole and a plug hole. The blocking ring is arranged at one end of the annular blocking plate, and one of the openings of the arc hole and the plug hole are in contact with the blocking ring. One end of the blocking ring is fixedly connected with a guide rod plugged into the plug hole, and one end of the guide rod passes through the plug hole and the vertical hole in sequence and is plugged into the air inlet.

[0009] In one of the embodiments, when the supply of crude oil and high-pressure air stops, the crude oil can not only separate solid impurities from the oil pipe through the blocking component to prevent the solid impurities from flowing back into the oil pipe, thereby reducing the burden of subsequent maintenance on the staff, but the blocking component can also separate the ring frame from the air pipe, which can prevent the crude oil from flowing back into the air pipe, which can effectively reduce the probability of oil and gas leakage, and there is no need to add a separate power source, which meets the requirements of green development of modern industry.

[0010] Furthermore, the number of the air inlets, arc holes, jacks and guide rods are the same and no less than ten.

[0011] In one embodiment, this can increase the flow channel of the raw oil and high-pressure air to ensure the spraying amount of atomized oil droplets.

[0012] Furthermore, a positioning ring groove plugged into the jack is formed at the other end of the guide rod, the inner diameter of the jack matches the minimum inner diameter of the positioning ring groove, and the diameter of the guide rod matches the inner diameter of the air inlet.

[0013] In one embodiment, this can ensure that the guide rod can move normally in the socket and the air inlet, so as to ensure that the guide rod can play a normal blocking role.

[0014] Furthermore, the positioning ring groove is arranged at a height a outside the insertion hole, the guide rod is arranged at a height b inside the air inlet, and the height ratio of a to b is two to one.

[0015] In one embodiment, this can ensure that the guide rod can be effectively connected to or separated from the air inlet, so as to ensure that the guide rod can normally block the air inlet.

[0016] Furthermore, the cross-sectional shape of one end of the guide rod is an arc shape, and the center point of the one end of the guide rod is arranged inside the air inlet.

[0017] In one of the embodiments, this can reduce the resistance of high-pressure air passing through the gap between the air inlet and the guide rod, thereby reducing the probability of the guide rod being blown off-center.

[0018] Furthermore, the vertical cross-section of the barrier ring is semicircular, and the horizontal cross-section dimensions of the arc hole and the insertion hole are both smaller than the horizontal cross-section dimension of the bottom surface of the barrier ring.

[0019] In one embodiment, this can ensure that the barrier ring can effectively block the arc hole and the plug hole, and effectively separate the impurities from the oil pipe.

[0020] Furthermore, an air guide ring groove connected to the air inlet is formed at one end of the ring frame, and the vertical cross-section of the air guide ring groove is an isosceles trapezoid.

[0021] In one embodiment, this can reduce the resistance of high-pressure air entering the air inlet to ensure the flow rate of high-pressure air.

[0022] Furthermore, a rotating ring fixedly connected to the ring frame is rotatably connected to the surface of the rotating seat, and balls distributed in a ring shape are embedded and installed on the surface of the rotating ring.

[0023] In one embodiment, this can reduce the rotational resistance of the ring frame to reduce the obstruction to the flow of crude oil and high-pressure air.

[0024] Furthermore, a rotating ring groove slidably connected to the ball is provided inside the rotating seat, and the vertical cross-sectional shapes of the rotating ring groove and the ball are both matching circles.

[0025] In one of the embodiments, this can effectively limit the running trajectory of the balls and improve the stability of the ring frame rotation.

[0026] The above-mentioned raw oil gun head with optimized carbon black structure uses the flow force of raw oil and high-pressure air to actively rotate the ring frame and the stainless steel filter mesh ring, which can not only throw solid impurities away from the stainless steel filter mesh ring under the action of rotating centrifugal force, but also solve the problem that the filter element in the existing raw oil gun head with anti-clogging for carbon black production is easy to accumulate impurities, increase the burden of crude oil passing through and the probability of damage to the filter element;

[0027] At the same time, the spiral plate can rotate and stir the high-pressure air and the raw oil, so that the raw oil and air are mixed more evenly, so as to improve the dispersion rate of the ejected raw oil droplets. The uniform distribution of the oil droplets reduces the difference between the carbon black particles, so that the produced carbon black products have better uniformity and consistency;

[0028] When the supply of crude oil and high-pressure air stops, the crude oil can not only separate the solid impurities from the oil pipe through the blocking component to prevent the solid impurities from flowing back into the oil pipe, thereby reducing the burden of subsequent maintenance on the staff, but the blocking component can also separate the ring frame from the air pipe, which can prevent the crude oil from flowing back into the air pipe, which can effectively reduce the probability of oil and gas leakage, and there is no need to add a separate power source, which meets the requirements of green development of modern industry.

[0044] Combine the following Figure 1 - Figure 7 A feedstock oil gun head for optimizing carbon black structure of the present invention is described.

[0045] In one embodiment, a raw oil gun head for optimizing carbon black structure includes an atomizing nozzle 100, one end of the atomizing nozzle 100 is fixedly connected and communicated with an air pipe 200, and the other end of the atomizing nozzle 100 is installed with a bolt 300, the rod of the bolt 300 penetrates the outside of the atomizing nozzle 100, the rod of the bolt 300 is threadedly connected with an oil pipe 400 arranged inside the air pipe 200, and the rod of the bolt 300 is sleeved with a guide filter mechanism 500 arranged between the air pipe 200 and the oil pipe 400;

[0046] The atomizing nozzle 100 includes a cylindrical barrel, and the corner of one end of the cylindrical barrel is beveled. The beveled surface is provided with an atomizing nozzle. The atomizing nozzle is designed with an inclined angle. The angled design enables the atomized oil droplets to penetrate more deeply into the carbon black particles, promotes the close packing of the carbon black particles and the optimization of the pore structure, thereby improving the compressed oil absorption performance of the carbon black. The uniform distribution of the oil droplets reduces the difference between the carbon black particles, so that the produced carbon black product has better uniformity and consistency. By finely controlling the injection and distribution of the oil droplets, the waste and defective rate in the production process are reduced, the production efficiency and product quality are improved, and the The optimized design reduces oil and gas leakage and energy consumption, and meets the requirements of green development of modern industry. The surface of the cylindrical tube is provided with an oil inlet hole connected to both the atomizing spray hole and one of the ring openings 521. The oil pipe 400 includes a high-pressure resistant pipe, one end of which is fixedly connected to an inverted cone guide block, one end of which is provided with a thread groove. The rod of the bolt 300 passes through the cylindrical tube and the rotating seat 510 in sequence and is threadedly connected to the thread groove. The surface of the high-pressure resistant pipe is provided with an oil outlet hole connected to another ring opening 521. The axis lines of the oil inlet hole and the oil outlet hole intersect and form a right angle with the opening facing the bolt 300.

[0047] When the staff needs to assemble the above-mentioned gun heads together, the staff first passes the rod of the bolt 300 through the cylindrical tube, and then sets the rotating seat 510 in the guide filter mechanism 500 on the surface of the bolt 300, and then passes the high-pressure resistant pipe through the inner side of the air inlet pipe 200 and connects it with the threaded groove until the bolt 300 firmly connects the cylindrical tube, the rotating seat 510 and the high-pressure resistant pipe together.

[0048] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the guide filter mechanism 500 includes a rotating seat 510 sleeved on the rod of the bolt 300 and arranged between the air pipe 200 and the oil pipe 400, and a ring frame 520 is rotatably connected to the surface of the rotating seat 510. Two ring openings 521 are opened on the inner side of the ring frame 520 and are respectively connected to the inlet of the atomizing nozzle 100 and the outlet of the oil pipe 400. A stainless steel filter mesh ring 530 is fixedly connected to the inner side of the ring opening 521 connected to the inlet of the atomizing nozzle 100. A spiral plate 540 distributed in an annular shape is fixedly connected to the inside of the ring frame 520. An air inlet 522 distributed in an annular shape is opened at one end of the ring frame 520. The raw oil and high pressure The flow force of the air actively rotates the ring frame 520 and the stainless steel filter mesh ring 530, which can not only throw the solid impurities away from the stainless steel filter mesh ring 530 under the action of the rotating centrifugal force, but also solve the problem that the filter in the existing raw oil gun head with anti-clogging for carbon black production is easy to accumulate impurities, increase the burden of crude oil passing and the probability of filter damage; at the same time, the spiral plate 540 can rotate and stir the high-pressure air and the raw oil, so that the raw oil and air are mixed more evenly, so as to improve the dispersion rate of the ejected raw oil droplets. The uniform distribution of the oil droplets reduces the differences between the carbon black particles, so that the produced carbon black products have better uniformity and consistency.

[0049] The surface of the rotating seat 510 is rotatably connected to a rotating ring 560 fixedly connected to the ring frame 520, and the surface of the rotating ring 560 is embedded with annularly distributed balls 570, which can reduce the rotation resistance of the ring frame 520, so as to reduce the obstruction to the flow force of the crude oil and the high-pressure air; the interior of the rotating seat 510 is provided with a rotating ring groove 511 slidably connected to the balls 570, and the vertical cross-sectional shapes of the rotating ring groove 511 and the balls 570 are both matched circles, which can effectively limit the running track of the balls 570 and improve the rotation stability of the ring frame 520;

[0050] When the crude oil flows along the inside of the ring frame 520, the external air injection mechanism simultaneously injects high-pressure air into the air pipe 200. The high-pressure air enters the inside of the ring frame 520 through the air inlet 522. The high-pressure air simultaneously drives the spiral plate 540 to rotate. The spiral plate 540 quickly stirs the crude oil and the high-pressure air together, which can disperse the crude oil more thoroughly and make the crude oil sprayed from the atomizing nozzle more thoroughly dispersed.

[0051] like Figure 4 , Figure 5 and Figure 6As shown, the surface of the spiral plate 540 is provided with evenly distributed vertical holes 541, the guiding filter mechanism 500 also includes a blocking assembly 550, the blocking assembly 550 includes an annular blocking plate 551 and a blocking ring 554, the annular blocking plate 551 is arranged between the rotating seat 510 and the stainless steel filter mesh ring 530, one end of the annular blocking plate 551 is provided with an arc hole 552 and a plug hole 553, the blocking ring 554 is arranged at one end of the annular blocking plate 551, one of the openings of the arc hole 552 and the plug hole 553 are in contact with the blocking ring 554, the interior of the air inlet 522 is plugged with a guide rod 555, and the guide rod 555 is The top end passes through the air inlet 522, the vertical hole 541 and the plug hole 553 in sequence and is fixedly connected to the blocking ring 554. When the crude oil and high-pressure air stop supplying and flowing, the crude oil can not only separate the solid impurities from the oil pipe 400 through the blocking component 550, but also prevent the solid impurities from flowing back into the oil pipe 400, so as to reduce the burden of subsequent maintenance on the staff. At the same time, the blocking component 550 can also separate the ring frame 520 from the air pipe 200, which can prevent the crude oil from flowing back into the air pipe 200, which can effectively reduce the probability of oil and gas leakage, and there is no need to add a separate power source, which meets the requirements of green development of modern industry.

[0052] The number of the air inlet 522, the arc hole 552, the plug hole 553 and the guide rod 555 are all the same and no less than ten, which can increase the circulation channel of the raw oil and the high-pressure air to ensure the spraying amount of the atomized oil droplets; the other end of the guide rod 555 is provided with a positioning ring groove 556 plugged with the plug hole 553, the inner diameter of the plug hole 553 matches the minimum inner diameter of the positioning ring groove 556, and the diameter of the guide rod 555 matches the inner diameter of the air inlet 522, which can ensure that the guide rod 555 can move normally in the plug hole 553 and the air inlet 522 to ensure that the guide rod 555 can play a normal blocking role; the height of the positioning ring groove 556 set outside the plug hole 553 is a, and the height of the guide rod 555 set inside the air inlet 522 is b, and the height ratio of a to b is two to one, which can ensure that the guide rod 555 can be effectively connected or separated from the air inlet 522 to ensure The guide rod 555 can normally block the air inlet 522; the cross-sectional shape of one end of the guide rod 555 is an arc shape, and the center point of one end of the guide rod 555 is set inside the air inlet 522, which can reduce the resistance of high-pressure air passing through the gap between the air inlet 522 and the guide rod 555, so as to reduce the probability of the guide rod 555 being blown obliquely; the vertical cross-sectional shape of the blocking ring 554 is semicircular, and the horizontal cross-sectional dimensions of the arc hole 552 and the plug hole 553 are both smaller than the horizontal cross-sectional dimensions of the bottom surface of the blocking ring 554, which can ensure that the blocking ring 554 can effectively block the arc hole 552 and the plug hole 553, and effectively separate impurities from the oil pipe 400; one end of the ring frame 520 is provided with an air guide ring groove 523 connected to the air inlet 522, and the vertical cross-sectional shape of the air guide ring groove 523 is an isosceles trapezoid, which can reduce the resistance of high-pressure air entering the air inlet 522, so as to ensure the flow rate of high-pressure air;

[0053] In the process of crude oil and high-pressure air passing through the arc hole 552 and the air inlet 522 respectively, the blocking ring 554 and the guide rod 555 can respectively block the crude oil and the high-pressure air. At this time, the crude oil and the high-pressure air can also push the blocking ring 554 and the guide rod 555 apart respectively, so that the crude oil and the high-pressure air can flow smoothly toward the direction of the atomizing nozzle 100. When the high-pressure air and the crude oil stop flowing, the crude oil can drive the blocking ring 554 to move back in the process of flowing into the air pipe 200. The blocking ring 554 drives the guide rod 555 to move back. When the blocking ring 554 is in contact with the annular blocking plate 551, the guide rod 555 can also be inserted to block the air inlet 522 simultaneously. This can not only prevent the impurities intercepted inside the ring frame 520 from flowing back toward the direction of the oil pipe 400, so that the staff can concentrate on cleaning later, but also prevent the crude oil from carrying solid impurities to flow into the interior of the air pipe 200, so as to achieve the purpose of reducing the waste of crude oil.

[0054] Working principle: After the oil pipe 400 injects the raw oil into the interior of the ring frame 520 through the ring opening 521 connected thereto, the raw oil enters the interior of the atomizing nozzle 100 through the stainless steel filter mesh ring 530. In this process, the stainless steel filter mesh ring 530 filters out solid impurities in the raw oil passing through. At the same time, the raw oil impacts the spiral plate 540 along the ring frame 520, and the spiral plate 540 drives the ring frame 520 and the rotating ring 560 to rotate along the rotating seat 510. The ring frame 520 drives the stainless steel filter mesh ring 530 and the solid impurities to rotate through another ring opening 521. The solid impurities are thrown away from the stainless steel filter mesh ring 530 under the action of the rotating centrifugal force, and are firmly confined therein by the ring frame 520, which can prevent the solid impurities from being retained on the surface of the stainless steel filter mesh ring 530 for a long time, so that the stainless steel filter mesh ring 530 always remains unobstructed, so as to solve the problem that the filter element in the existing raw oil gun head with anti-clogging for carbon black production is easy to accumulate impurities, which increases the burden of crude oil passing and the probability of damage to the filter element.

[0055] It should be noted that the high-pressure resistant pipes and stainless steel filter mesh ring 530 in the above description are both devices with relatively mature application of existing technologies. The specific models can be selected according to actual needs. At the same time, the high-pressure resistant pipes and stainless steel filter mesh ring 530 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0056] The technical features of the above embodiments may 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.

[0057] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
