Description

Technical Field

[0001] This invention relates to the field of distribution device technology, and more specifically to an automatic proportioning and redistribution system and method for catalyst powder. Background Technology

[0002] During catalyst forming, small amounts of binders and lubricants are often added to improve catalyst strength, reduce friction within the material or between the material and the mold, and improve pore structure. Catalyst powder distribution involves two parts: first, different powders are mixed according to different proportions; then, the mixed powder is redistributed to storage equipment. Because the amount of these additives is small, manual feeding is usually performed. Operators add each catalyst powder to the mixing tank according to the proportions, then mix and store it or proceed to the next process. However, this method requires significant labor costs and has low production efficiency. Currently, some publicly available automated mixing devices exist.

[0003] CN115920763B discloses an automatic proportioning device for ultrafine powders and its implementation method. Through a spiral feeding and a rotating mesh feeding structure, ultrafine powders can be converted from an agglomerated state to a loose, slowly dispensing state, achieving uniform and controllable dispensing and precise proportioning. However, this method is not applicable to the proportioning of catalyst powders in this field, nor does it involve material redistribution. Furthermore, because this device requires slow material dispensing to achieve precise proportioning, its production efficiency is low.

[0004] CN219399968U discloses an automatic proportioning and mixing device for calcium carbonate mixed powder, which addresses the problem that open-type automatic proportioning and mixing devices for small and medium-sized calcium carbonate mixed powder easily generate dust during operation, causing pollution of the production workshop's air environment and affecting the health of workers. This method can achieve cleaner production, but it also cannot achieve redistribution, and the production capacity of a single mixing device is limited, thus its application is restricted. Summary of the Invention

[0005] The main technical problem solved by this invention is that existing mixing devices cannot achieve continuous automatic proportioning and redistribution of catalyst powder, resulting in low production efficiency.

[0006] To achieve the above objectives, a first aspect of the present invention provides an automatic proportioning and redistribution system for catalyst powder, comprising:

[0011] In some embodiments, a valve body is provided in the feed pipe, and a silo weighing instrument is provided in the silo. The silo weighing instrument is communicatively connected to the valve body to control the opening and closing of the valve body.

[0012] In some embodiments, the mixing silo is equipped with a mixing silo weighing device, which is communicatively connected to the silo weighing device to control the opening and closing of the silo outlet and the mixing silo inlet.

[0013] In some embodiments, a connecting pipe is detachably provided between the outlet of the silo and the inlet of the mixing silo.

[0014] In some embodiments, a stirring mechanism is detachably provided in the mixing chamber.

[0015] In some implementations, the number of feed pipes is one or more.

[0016] The second aspect of the present invention provides an automatic proportioning and redistribution method for catalyst powder, which is accomplished using the automatic proportioning and redistribution system for catalyst powder.

[0017] In some implementations, the following are included:

[0018] 1) One type of catalyst powder of a preset type is transported to the silo through the feed pipe. Multiple mixing chambers pass through the outlet of the silo in sequence and receive a preset weight of catalyst powder. At the same time, the catalyst powder in the mixing chamber is stirred.

[0019] 2) The mixing chamber is transported to the silo by the conveying track. The feeding operation of other preset types of catalyst powder is repeated in step 1).

[0020] 3) Selectively transfer the mixed powder from each of the mixing bins to the storage tank.

[0021] In some implementations, the following are included:

[0022] 1) One type of catalyst powder of a preset type is conveyed to the silo through the feed pipe, and multiple mixing chambers sequentially pass through the outlet of the silo and receive a preset weight of catalyst powder;

[0023] 2) Selectively transfer the catalyst powder from each of the mixing chambers to the storage tank;

[0024] 3) The mixing chamber is transported to the silo via the conveyor track. The feeding operations of other preset types of catalyst powder are repeated in steps 1) to 2).

[0025] In some embodiments, the feed rate of the catalyst powder is less than or equal to 2 / 3 of the silo capacity.

[0026] Through the above technical solution, the automatic proportioning and redistribution system for catalyst powder is set up to consist of a feeding system, a transfer system, and a storage tank. The catalyst powder is transported from the silo to the mixing chamber to achieve the proportioning of the powder; the mixed powder is transported from the mixing chamber to the storage tank to achieve the redistribution of the powder; the mixing chamber is circulated between the feeding system and the storage tank by a conveyor track, so as to realize the continuous automatic proportioning and redistribution of catalyst powder.

[0036] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0037] To address the problems of existing mixing devices being unable to achieve continuous automatic proportioning and redistribution of catalyst powder and resulting in low production efficiency, the first aspect of this invention provides an automatic proportioning and redistribution system for catalyst powder, comprising:

[0038] The transfer system 4 includes a conveyor track 5 and multiple mixing bins 6 set on the conveyor track 5;

[0039] Feeding system 1 includes a feeding pipe 2 and a hopper 3 connected to the feeding pipe 2; and

[0040] Multiple storage tanks 7 are installed downstream of the transfer system 4;

[0041] The hopper 3 is configured to deliver a preset type and preset weight of catalyst powder to each mixing hopper 6, and each storage tank 7 is configured to receive one or more mixed powders output from the mixing hopper 6.

[0042] like Figure 1 As shown, the mixing chamber 6 can be a sealable box or tank for receiving and mixing various catalyst powders to prepare a mixed powder. A conveyor belt can be installed in the conveying track 5 to transport the mixing chamber 6 to multiple storage tanks 7. Wheels can be further installed below the mixing chamber 6 to facilitate handling. Guide grooves that cooperate with the wheels can also be opened in the conveying track 5 to transport the mixing chamber 6. The transfer system 4 can be designed with different models of mixing chambers 6 and conveying tracks 5 according to production needs, or a circular conveyor or a multi-angle sorting machine can be directly selected.

[0043] The feed pipe 2 is used to supply different types of catalyst powder to the automatic proportioning and redistribution system of catalyst powder. The silo 3 is used to temporarily store the catalyst powder and transport it to the mixing silo 6. The silo 3 can be sealed.

[0044] Since the types and weights of catalyst powders required for preparing different types of catalysts are different, it is necessary to pre-set the types and weights of catalyst powders that each mixing chamber 6 can receive from the material chamber 3. This operation can be achieved by connecting the material chamber 3 and the mixing chamber 6 to the control system.

[0045] Each mixing chamber 6 can mix and output mixed powder for a single catalyst, and each storage tank 7 can also store mixed powder for a single catalyst. Thus, the mixing chamber 6 can be connected to and fed into the storage tank 7 storing mixed powder of the same type of catalyst. There are multiple mixing chambers 6 and storage tanks 7; that is, mixed powder of the same catalyst can be obtained by mixing in at least one mixing chamber 6, and at least one storage tank 7 for storing the mixed powder of that catalyst can also be provided. Therefore, each storage tank 7 is configured to receive mixed powder output from one or more mixing chambers 6.

[0046] Through the above technical solution, the automatic proportioning and redistribution system for catalyst powder is set up to consist of a feeding system 1, a transfer system 4, and multiple storage tanks 7. The catalyst powder is transported from the silo 3 to the mixing chamber 6 to achieve the proportioning of the powder; the mixed powder is transported from the mixing chamber 6 to the storage tanks 7 to achieve the redistribution of the powder; the mixing chamber 6 is circulated between the feeding system 1 and the storage tanks 7 by the conveying track 5, so as to realize the continuous automatic proportioning and redistribution of catalyst powder. The whole system greatly improves the production efficiency of the catalyst forming process.

[0047] In some embodiments, a valve body is provided in the feed pipe 2, and a hopper weighing instrument 31 is provided in the hopper 3. The hopper weighing instrument 31 is communicatively connected to the valve body to control the opening and closing of the valve body.

[0048] like Figure 1 As shown, the silo weighing instrument 31 can be installed at the bottom of the silo 3 to calculate the weight of the catalyst powder fed into the silo 3 through the feed pipe 2 in real time, and transmit the weight signal to the valve body in the feed pipe 2. When the weight of the catalyst powder in the silo 3 reaches the set value, the valve body in the feed pipe 2 is closed; when the weight of the catalyst powder in the silo 3 is 0, the valve body in the feed pipe 2 is reopened.

[0049] In some embodiments, the mixing chamber 6 is equipped with a mixing chamber weighing device 61, which is communicatively connected to the silo weighing device 31 to control the opening and closing of the discharge port of the silo 3 and the inlet of the mixing chamber 6.

[0050] like Figure 1 As shown, the mixing chamber weighing device 61 can be installed at the bottom of the mixing chamber 6 to calculate the weight of the catalyst powder fed into the mixing chamber 6 from the silo 3 in real time, and transmit the weight signal to the weighing device 31 of the silo 3. Whenever a mixing chamber 6 circulates to the bottom of the silo 3, the outlet of the silo 3 and the inlet of the mixing chamber 6 are opened; when the weight of the catalyst powder in the mixing chamber 6 reaches the set value, the outlet of the silo 3 and the inlet of the mixing chamber 6 are closed.

[0051] In some embodiments, a connecting pipe is detachably provided between the discharge port of the hopper 3 and the inlet of the mixing hopper 6.

[0052] To prevent dust spillage and improve the cleanliness and hygiene of the production environment, a connecting pipe is used to connect the discharge port of silo 3 to the inlet of mixing silo 6 during the feeding process. Sealing gaskets can be pre-fixed at the discharge port of silo 3 and the inlet of mixing silo 6 to further improve sealing. Since silo 3 needs to connect with multiple mixing silos 6, the connecting pipe is detachable. Specifically, a robotic arm can be positioned near the discharge port of silo 3 to grasp and adjust the position of the connecting pipe, thus achieving the connection between the discharge port of silo 3 and the inlet of mixing silo 6. In some other embodiments, one end of the connecting pipe can be fixedly connected to the discharge port of silo 3, while the other end can be detachably connected to the inlet of mixing silo 6.

[0053] In some embodiments, a stirring mechanism is detachably installed in the mixing chamber 6. The stirring mechanism can be a stirring paddle used to mix various catalyst powders. Furthermore, the stirring mechanism can be driven by a motor, and the mixing chamber weighing instrument 61 of the mixing chamber 6 can be communicatively connected to the motor. When the mixing chamber weighing instrument 61 detects the presence of catalyst powder in the mixing chamber 6, it transmits a weight signal to the motor, which then starts stirring and mixing. Additionally, a timing instrument can be installed on the mixing chamber 6 to precisely control the mixing time.

[0054] In some implementations, the number of feed pipes 2 is one or more. For example... Figure 1 As shown, each catalyst powder can be conveyed to the silo 3 from the same feed pipe 2, or each type of catalyst powder can be conveyed to the silo 3 separately from a separate feed pipe 2. The feed pipe 2 and the feed inlet of the silo 3 can also be configured to be sealed.

[0055] The second aspect of the present invention provides an automatic proportioning and redistribution method for catalyst powder, which is accomplished using an automatic proportioning and redistribution system for catalyst powder.

[0056] The automatic proportioning and redistribution system may include a control system, which is connected to the valve body, silo weighing instrument 31, mixing silo weighing instrument 61 and motor in the aforementioned automatic proportioning and redistribution system, so as to realize the continuous operation of the entire process of catalyst powder distribution, which greatly improves production efficiency.

[0057] The mixing chamber 6 is circulated between the feeding system 1 and the storage tank 7 by the conveyor track 5, realizing the continuous automatic proportioning and redistribution of catalyst powder. Actual production verification shows that, compared to traditional manual intermittent feeding, the automatic proportioning and redistribution method of this application can reduce the number of workers by 2-3.

[0058] The feed pipe 2, silo 3, and mixing chamber 6 in the feeding system 1 are all connected in a sealed manner when conveying catalyst powder to prevent particles or dust from spilling out and polluting the environment.

[0059] In some implementations, the following are included:

[0060] 1) One type of catalyst powder of a preset type is conveyed to the silo 3 through the feed pipe 2. Multiple mixing chambers 6 pass through the outlet of the silo 3 in sequence and receive the preset weight of catalyst powder. At the same time, the catalyst powder in the mixing chamber 6 is stirred.

[0061] 2) Use the conveyor track 5 to transport the mixing bin 6 to the material bin 3 in a cycle. Repeat step 1) for feeding other preset types of catalyst powder.

[0062] 3) Selectively transfer the mixed powder in each mixing chamber 6 to the storage tank 7.

[0063] It should be noted that in step 2), the silo 3 is set to receive a single type of catalyst powder each time. Therefore, in each cycle, the silo 3 also feeds the same type of catalyst powder into multiple mixing chambers 6. Since each mixing chamber 6 needs to receive multiple catalyst carriers, the mixing chamber 6 needs to circulate multiple times on the conveying track 5 until the silo 3 has fed all types of catalyst powder into the mixing chamber 6.

[0064] In some implementations, the following are included:

[0065] 1) One type of catalyst powder of a preset type is conveyed to the silo 3 through the feed pipe 2, and multiple mixing chambers 6 pass through the discharge port of the silo 3 in sequence and receive the preset weight of catalyst powder.

[0066] 2) Selectively transfer the catalyst powder from each mixing chamber 6 to the storage tank 7;

[0067] 3) The mixing bin 6 is transported to the material bin 3 by the conveyor track 5. The feeding operation of other preset types of catalyst powder is repeated in steps 1) to 2).

[0068] The automatic proportioning and redistribution system for catalyst powder can also be used as a catalyst powder transportation system. Each mixing chamber 6 is used to transport one type of catalyst powder. In this case, there is no need to stir and mix the materials in the mixing chamber 6. The mixing chamber 6 can be directly transported by the conveying pipeline 5 to the corresponding storage tank 7 that stores the same type of catalyst powder for feeding.

[0069] In some embodiments, the feed rate of catalyst powder is less than or equal to 2 / 3 of the capacity of silo 3. This effectively prevents catalyst powder from overflowing from silo 3, overloading silo 3 and causing safety hazards, or clogging of the outlet of silo 3 by catalyst powder. The capacity of silo 3 can be monitored by installing a level gauge on silo 3.
