Description

Technical Field

[0001] This utility model relates to the field of catalyst production technology, and in particular to a catalyst production feeding device. Background Technology

[0002] In the catalyst forming process, the catalyst powder raw material needs to be transported to a 28-meter platform by a blower to form negative pressure, and then formed step by step downwards.

[0003] The existing catalyst extraction device has the following problems:

[0004] (1) Pipes are prone to blockage: During the material suction process, if the operator is not careful, the pipes may become blocked. After the blockage, the connecting hose or other air inlet needs to be disassembled, which increases the working cost.

[0005] (2) Affecting the suction effect of the induced draft fan: Since the induced draft fan pipeline connects multiple devices, if the pipeline is blocked, it will affect the suction and dust removal effect of other devices, causing a series of chain reactions, which will ultimately affect the product output and quality.

[0006] (3) High labor costs: Since the amount of material to be sucked needs to be controlled at all times to prevent blockage, an employee can only operate one suction hose, resulting in high labor costs and low efficiency.

[0007] A converter catalyst automatic suction robot is disclosed in Chinese patent document CN120395766A. This robot includes a negative pressure device and a suction pipe; a crossbeam with its axial end located at the center of the converter and its free end located on the outer ring of the converter, the free end rotating about the center of the converter; an X-axis track fixedly installed on the top surface of the crossbeam, with an X-axis moving block slidably mounted on it; a Y-axis track fixed to the X-axis moving block, with a Y-axis moving block slidably mounted on it; a Z-axis track fixed to the upper side wall of the Y-axis moving block, with a Z-axis moving block slidably mounted on it; and a suction pipe fixedly installed on the Z-axis moving block, its lower end connecting to the converter tube array and its upper end connected to the negative pressure device via a flexible pipe. This design eliminates the need for a ground-mounted frame support, allowing the robot to be directly installed on the top surface of the converter for easy movement; it achieves automated catalyst cleaning and reduces dangerous manual operations. However, blockage of the robot's pipes can affect the suction and dust removal efficiency of other equipment, causing a series of chain reactions.

[0008] To address the shortcomings of the existing technology, providing a catalyst production feed device is a problem worthy of research. Utility Model Content

[0009] The purpose of this invention is to overcome the shortcomings of easy clogging of the suction port and pipe, and to provide a catalyst production suction device that achieves the technical effect of uniform suction without clogging.

[0010] The objective of this utility model is achieved through the following technical solution:

[0011] A catalyst production feed device includes a feed pipe, a main feed port fixedly connected to the bottom of the feed pipe, a three-way port fixedly connected to one side of the main feed port, and a support mechanism disposed outside the main feed port, forming a basic structure of a feed device with dual air intake channels. The introduction of the three-way port provides a structural basis for optimizing airflow and preventing blockage.

[0012] Optionally, the suction pipe is made of silicone tubing. The top of the suction pipe is connected to the blower. The catalyst powder is drawn to the catalyst forming device at a high position through the main suction port and the three-way port at the end of the suction pipe. It is then subjected to multi-stage pressure forming to finally produce catalyst granules or tablets. The three-way pipe with two openings increases the air inlet to circulate the air duct, ensuring a stable feed rate without clogging, and greatly improving work efficiency.

[0013] Optionally, the opening direction of the main suction port is opposite to that of the opening direction of the three-way port. The total weight of the main suction port and the three-way port is greater than the resistance encountered by the suction device when entering the catalyst powder. By limiting the weight of the three-way pipe, after the suction pipe and suction port are placed into the catalyst powder, they can sink under their own weight, eliminating the need for long-term control of the suction pipe. This allows one worker to operate multiple pipes simultaneously, saving labor costs.

[0014] Optionally, the support mechanism includes a limiting block fixedly connected to the outside of the main suction port, a clamping ring sleeved on the outside of the main suction port, and a support leg fixedly connected to the bottom of the clamping ring, thus constructing a height-adjustable support system. The support leg can prevent the main suction port from directly contacting the bottom of the hopper, avoiding the suction port from being blocked, while ensuring that the suction port is in a low position to fully suck up the bottom powder.

[0015] Optionally, the limiting blocks are distributed in multiple rings on the outside of the main suction port, the height difference between adjacent limiting blocks is equal, and the bottom groove shape of the limiting blocks is adapted to the cross-sectional shape of the clamping ring.

[0016] The clamping ring has a notch on one side and is made of alloy spring steel. By setting a clamping ring with a support leg on the outside of the main suction port, the main suction port is clamped on the main suction port. When the main suction port is about to touch the bottom, the support leg can contact the bottom for support, so as to avoid the main suction port from contacting the bottom of the hopper and affecting the suction effect.

[0017] Optionally, a filter screen is fixedly connected to the top of the three-way port. The middle of the filter screen protrudes upward. By setting the filter screen at the top of the three-way port, the powder entering the three-way port is filtered to prevent clumps of powder from entering the three-way port and reduce the possibility of blockage during catalyst suction.

[0018] Positive and beneficial effects:

[0019] 1. The catalyst production feed device constitutes a basic structure of a feed device with dual air intake channels. The introduction of the three-way port provides a structural basis for optimizing airflow and preventing blockage.

[0020] 2. The catalyst production feeding device uses a silicone hose that is flexible and not easily broken, which further reduces the risk of pipeline blockage. The core function of the three-way port is to introduce additional air to balance the negative pressure and stabilize the airflow, thereby ensuring a stable feeding amount and fundamentally preventing blockage. This brings about a systematic and beneficial effect of improving work efficiency, stabilizing product quality and output, and not affecting the dust removal effect of other parallel equipment.

[0021] 3. The catalyst production feeding device has a height-adjustable support system. The support legs can prevent the main feeding port from directly contacting the bottom of the hopper, avoiding the port from being blocked, while ensuring that the port is in a low position to fully suck up the powder at the bottom.

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] Example 1

[0031] like Figures 1 to 6 As shown, a catalyst production feeding device includes a feeding pipe 1, characterized in that: it also includes a main feeding port 2 fixedly connected to the bottom of the feeding pipe 1, a three-way port 3 fixedly connected to one side of the main feeding port 2, and a support mechanism disposed on the outside of the main feeding port 2, forming a basic structure of a feeding device with dual air intake channels. The introduction of the three-way port 3 provides a structural basis for optimizing airflow and preventing blockage.

[0032] like Figure 1 As shown, the material of the suction pipe 1 is a silicone hose. The top of the suction pipe 1 is connected to the blower. The catalyst powder is drawn to the catalyst forming device at a high position through the main suction port 2 and the three-way port 3 at the end of the suction pipe 1. It is then subjected to multi-stage pressure forming to finally produce catalyst granules or tablets. The three-way pipe with two openings increases the air inlet to circulate the air duct, ensuring a stable feed rate without clogging, which greatly improves work efficiency, stabilizes the air volume, and further improves product quality and output. The silicone hose has the advantages of good flexibility and is not easy to break, which can further reduce the risk of pipe blockage. The core function of the three-way port is to introduce additional air to balance the negative pressure and stabilize the airflow, thereby ensuring a stable feed rate and fundamentally preventing blockage. This brings about a systematic and beneficial effect of improving work efficiency, stabilizing product quality and output, and not affecting the dust removal effect of other parallel equipment.

[0033] Furthermore, since the pipes are not clogged, the dust removal effect of other equipment connected to the induced draft fan pipes will not be affected, resulting in less dust in the finished product, higher output, and higher quality.

[0034] like Figure 1 As shown, the opening direction of the main suction port 2 is opposite to that of the opening direction of the three-way port 3. The total weight of the main suction port 2 and the three-way port 3 is greater than the resistance encountered by the suction device when entering the catalyst powder. By limiting the weight of the three-way pipe, after the suction pipe and the suction port are placed into the catalyst powder, they can sink under their own weight. There is no need to control the suction pipe for a long time, which allows one person to operate multiple pipes at the same time, saving labor costs.

[0035] Example 2

[0036] like Figures 2 to 6As shown, the support mechanism includes a limiting block 4 fixedly connected to the outside of the main suction port 2, a clamping ring 5 sleeved on the outside of the main suction port 2, and a support leg 6 fixedly connected to the bottom of the clamping ring 5, thus constructing a height-adjustable support system. The support leg 6 can prevent the main suction port 2 from directly contacting the bottom of the hopper, avoiding the suction port from being blocked, while ensuring that the suction port is in a low position to fully suck up the bottom powder.

[0037] like Figures 2 to 6 As shown, the limiting blocks 4 are distributed in multiple rings on the outside of the main suction port 2. The height difference between adjacent limiting blocks 4 is equal, and the bottom groove shape of the limiting blocks 4 is adapted to the cross-sectional shape of the clamping ring 5.

[0038] A notch is provided on one side of the clamping ring 5. The clamping ring 5 is made of alloy spring steel. By setting the clamping ring 5 with the support leg 6 on the outside of the main suction port 2, the main suction port 2 is clamped on the main suction port 2. When the main suction port is about to touch the bottom, the support leg 6 can contact the bottom for support, so as to avoid the main suction port 2 from contacting the bottom of the hopper and affecting the suction effect. In addition, by adjusting the clamping ring 5 in conjunction with the limiting blocks 4 of different heights, the height difference between the support leg 6 and the bottom of the main suction port 2 can be increased, so as to realize the adjustment of the support height. This allows the main suction port 2 to be supported to avoid touching the bottom while fully sucking the catalyst powder at the bottom of the hopper.

[0039] like Figures 2 to 5 As shown, a filter screen 7 is fixedly connected to the top of the three-way port 3. The middle part of the filter screen 7 protrudes upward. By setting the filter screen 7 at the top of the three-way port 3, the powder entering the three-way port 3 is filtered to prevent the powder from clumping into the three-way port 3 and reduce the blockage during the catalyst suction process.

[0040] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
