Abstract
Description
Technical Field
[0001] This disclosure relates to the field of pneumatic material transport technology, and in particular to a static weighing silo feeding device and system. Background Technology
[0002] With the development of technology, the blast furnace slag smelting process has been continuously optimized, and its production capacity has been continuously improved through tapping potential. The amount of reducing agent used has also gradually increased. In the production process, a large amount of solid reducing agent is transported by a pneumatic conveying system to the static weighing silo at the top of the carbonization furnace via a silo pump. Finally, it is gradually added into the furnace through metering for reduction smelting.
[0003] Furthermore, the feeding device of a static weighing silo must meet the requirements of the weighing sensor; otherwise, it will affect the metering of materials used, leading to accidents in the smelting process and seriously impacting product quality. In related technologies, the original feeding device used a flexible connection method, typically employing wear-resistant metal hoses or wear-resistant rubber hoses. However, in this method, the metal hoses or wear-resistant rubber hoses are subjected to long-term erosion by the conveyed materials, resulting in frequent wear and leakage at the hose connection flanges and clamps, severely affecting material conveying and also causing a series of safety and environmental problems. The high failure rate of the feeding device severely restricts the company's continuous and economical production, increases the consumption of spare parts, and also brings significant operational safety risks.
[0004] Therefore, how to effectively and efficiently complete the material feeding of static weighing silos in the long term has become an urgent problem to be solved. Utility Model Content
[0005] One of the technical problems that this disclosure aims to solve is: how to address the short service life of conveying devices during the material feeding process of silos.
[0006] To solve the above-mentioned technical problems, in a first aspect, this utility model provides a static weighing silo feeding device, comprising: a silo and a rigid pipe, wherein the silo has a feeding hole on its side, and one end of the rigid pipe is inserted into the silo through the feeding hole for conveying material to the silo through the rigid pipe.
[0007] In conjunction with the first aspect, in one possible implementation of the first aspect, the hopper further includes: a sleeve, one end of which is connected to the feed port, and the other end of which is used to cover the rigid pipe, the rigid pipe being inserted into the feed port through the sleeve.
[0008] In conjunction with the first aspect, in one possible implementation of the first aspect, the rigid conduit further includes: a fastener wrapped around the outer surface of the sleeve for securing the sleeve to the rigid conduit.
[0009] In conjunction with the first aspect, in one possible implementation of the first aspect, the rigid pipe has an elbow at one end inside the silo, the elbow being used to change the direction in which material enters the silo.
[0010] In conjunction with the first aspect, in one possible implementation of the first aspect, a baffle is provided on the outer side of the elbow, the baffle being used to prevent material spillage after the elbow wears down.
[0011] In conjunction with the first aspect, in one possible implementation of the first aspect, the baffle is fitted to the outer wall of the elbow.
[0012] In conjunction with the first aspect, in one possible implementation of the first aspect, the elbow has a first bevel at the connection with the rigid pipe.
[0013] In conjunction with the first aspect, in one possible implementation of the first aspect, the connection between the rigid pipe and the elbow has a second bevel that mates with the first bevel.
[0014] In conjunction with the first aspect, in one possible implementation of the first aspect, the rigid pipe further includes: a pipe support for fixing the rigid pipe so that the rigid pipe is horizontal with the feed hole opening.
[0015] Secondly, this utility model provides a static weighing silo feeding system, including: a silo pump conveying pipe, a connector, and a static weighing silo feeding device according to the first aspect or any corresponding embodiment, wherein the silo pump conveying pipe is connected to the rigid pipe through the connector.
[0016] Through the above technical solution, this disclosure provides a static weighing silo feeding device and system. The device includes a silo and a rigid pipe. The silo has a feeding hole on its side, and one end of the rigid pipe is inserted into the silo through the feeding hole to transport materials to the silo.

[0030] like Figure 1 As shown, this utility model discloses a static weighing hopper feeding device, comprising: a hopper 1 and a rigid pipe 2, wherein,
[0031] The silo 1 has a feed hole 11 on its side. One end of the rigid pipe 2 is inserted into the silo 1 through the feed hole 11 to transport materials to the silo 1 through the rigid pipe 2.
[0032] Specifically, rigid pipe 2 is a straight-through pipe, eliminating the flexible connection of the original design and directly connecting to the silo. The rigid pipe can be made of cold-fluid seamless steel or other materials. Typically, when using cold-fluid seamless steel, ordinary carbon steel Q235 or 20# is sufficient, with a material weight of 20g and dimensions of φ121*10. It should be understood that the weight, dimensions, and material of rigid pipe 2 can be set according to actual working conditions; this embodiment does not impose specific limitations on these. Furthermore, because rigid pipe 2 is a straight-through pipe, it avoids wear between the material and the pipe bends, effectively reducing wear points and ensuring smooth airflow and material transport within the pipe. It also ensures no interference between the feed pipe and the inner wall of the static silo, thus not affecting the weighing effect of the static scale. Moreover, the use of rigid pipe 2 further reduces the consumption of flexible pipe spare parts, lowers the probability of pipe leakage, and allows for quick maintenance, significantly reducing the labor intensity of manual maintenance.
[0033] Specifically, an additional feed hole 11 is added at the feed inlet of silo 1. The conveying pipe enters the silo through the feed hole 11 in a centrally located manner, effectively isolating it from the inner wall of the silo and avoiding the impact on the weighing effect due to rigid contact points. Typically, the size of the feed hole 11 is 200mm, but it can be set according to the actual working conditions. This embodiment does not impose a specific limitation on this.
[0034] Through the above technical solution, this disclosure provides a static weighing silo feeding device and system. The device includes a silo and a rigid pipe. The silo has a feeding hole on its side, and one end of the rigid pipe is inserted into the silo through the feeding hole to transport materials to the silo. This invention utilizes the feeding hole on the side of the silo in conjunction with the rigid pipe, using the rigid pipe as the material conveying pipe. In this process, by using the rigid pipe as the material conveying pipe, wear on the flexible pipe and pipe connections during transportation is effectively avoided. Furthermore, the use of a rigid pipe reduces the impact of material erosion on the conveying pipe, thereby extending the service life of the rigid pipe.
[0035] In some alternative embodiments, the hopper 1 further includes a sleeve 12, one end of which is connected to the feed hole 11, and the other end of which is used to cover the rigid pipe 2, the rigid pipe 2 being inserted into the feed hole 11 through the sleeve 12.
[0036] Specifically, the connection between one end of the sleeve 12 and the feed hole 11 can be achieved by welding the sleeve 12 to the inlet of the feed hole 11. The sleeve 12 can be a perforated steel sleeve or a sleeve made of other materials. Typically, the length of the sleeve 12 is about 500 mm, which can be set according to the actual working conditions. This embodiment does not make specific limitations on this.
[0037] Specifically, the length of the rigid pipe 2 inserted into the feed hole 11 through the sleeve 12 is usually about one-third of the length of the pipe entering the hopper. This can be set according to the actual working conditions, and this embodiment does not make a specific limitation on this.
[0038] In some alternative embodiments, the rigid pipe 2 further includes a fastener 24, which is wound around the outer surface of the sleeve 12 for securing the sleeve 12 to the rigid pipe 2.
[0039] Specifically, the fastener 24 is wound around the outer surface of the sleeve 12. By winding the fastener 24, a sealed space is formed between the sleeve 12 and the outer wall of the rigid pipe 2, so as to prevent dust and exhaust gas from overflowing from the feed inlet during material transportation.
[0040] Specifically, the fastener 24 can be made of waste dust collector bags or other materials. When using waste dust collector bags, the waste dust collector bags are cut in the middle to effectively wrap the fastener 24 and the rigid pipe 2, so as to prevent dust and exhaust gas from overflowing from the feed inlet during material transportation, which would affect safety and environmental protection.
[0041] In some alternative embodiments, the rigid pipe 2 has an elbow 21 at one end inside the silo 1, the elbow 21 being used to change the direction in which material enters the silo 1.
[0042] Specifically, since the rigid pipe is a straight pipe, the direction of the material entering the silo 1 is changed by setting an elbow 21 at one end of the rigid pipe 2 inside the silo 1, so as to avoid the pneumatic conveying material from scouring the inner wall of the silo 1 after entering the silo 1, thereby affecting the weighing effect of the static scale.
[0043] In some alternative embodiments, a baffle 22 is provided on the outer side of the elbow 21 to prevent material from spilling out after the elbow 21 is worn.
[0044] Specifically, since the elbow 21 is used to change the direction of material entering the hopper 1, the material will scour the inner wall of the elbow 21 during the pneumatic conveying process. The elbow 21 is provided with a baffle 22 on the outside, so that after the elbow 21 is scourted and worn by the material, the baffle 22 ensures the closed structure of the elbow 21, ensuring that the material will not overflow from the worn part of the elbow and cause scour of the inner wall of the hopper 1, thereby affecting the weighing effect of the static scale.
[0045] In some alternative embodiments, the baffle 22 is fitted to the outer wall of the elbow 21.
[0046] Specifically, since the baffle 22 is attached to the outer wall of the elbow 21, the elbow 21 is kept closed by the baffle 22 after being washed and worn by the material.
[0047] In some alternative embodiments, the elbow 21 has a first bevel at the connection with the rigid pipe 2.
[0048] Specifically, when welding the rigid pipe 2 to the elbow 21, a first bevel needs to be made at the elbow 21 to remove the surrounding burrs and flash. The first bevel welding shall be performed in accordance with relevant standards, such as GB / T985-2008.
[0049] In some alternative embodiments, the connection between the rigid pipe 2 and the elbow 21 has a second bevel that mates with the first bevel.
[0050] Specifically, when welding the rigid pipe 2 to the elbow 21, a second bevel needs to be made on the inside of the rigid pipe 2 to remove the surrounding burrs and flash. The welding of the second bevel shall be performed in accordance with relevant standards, such as GB / T985-2008.
[0051] In some alternative embodiments, the rigid pipe 2 further includes a pipe support 23, which is used to fix the rigid pipe 2 so that the rigid pipe 2 is horizontal with the opening position of the feed hole 11.
[0052] Specifically, the pipe support 23 is used to fix the rigid pipe 2 so that the rigid pipe 2 is flush with the opening of the feed hole 11. Thus, when the material enters the silo 1 through the rigid pipe 2, the rigid pipe 2 will not have a rigid contact point. Furthermore, the flushness between the rigid pipe 2 and the opening of the feed hole 11 further ensures the direction of the material entering the silo 1 as adjusted by the elbow 21, thereby preventing the material from scouring the inner wall of the silo 1.
[0053] like Figure 1 As shown, this utility model discloses a static weighing silo feeding system, including: a silo pump conveying pipe 3, a connector 31, and a static weighing silo feeding device as described in the foregoing embodiments, wherein,
[0054] The silo pump delivery pipeline 3 is connected to the rigid pipeline 2 via the connector 31.
[0055] Specifically, the material is transported to the silo 1 through the silo pump conveying pipe 3 and the rigid pipe 2. The connector 31 is used to fix the silo pump conveying pipe 3 and the rigid pipe 2. The connector 31 can be a flange connector or other connectors, which can be set according to the actual working conditions. This embodiment does not make specific limitations on this.
