Description

Technical Field

[0001] This invention relates to the field of benzyl hydroxamic acid production technology, specifically to a device for precisely proportioning and adding raw materials for benzyl hydroxamic acid production. Background Technology

[0002] Benzylhydroxamic acid production refers to the industrial process of preparing benzoylhydroxamic acid through chemical synthesis. This compound is an important organic chemical, mainly used in mineral flotation, organic synthesis, and other fields. It primarily uses benzoic acid (or methyl benzoate), hydroxylamine hydrochloride, and sodium hydroxide as basic raw materials. Some processes require the addition of concentrated sulfuric acid as a catalyst. During production, the proportions, order, and conditions of the feedstocks (such as benzoic acid, hydroxylamine hydrochloride, and sodium hydroxide) are strictly controlled to optimize reaction efficiency and product quality. The utility model disclosed in CN217829937U is a hydrogen peroxide production feeding device. Through the design of a feeding tank, a liquid level sensor, a pump, a time-delay alarm, a solenoid valve, and a discharge pipe, it can accurately add raw materials to the feeding tank during hydrogen peroxide preparation by pumping them into the tank. This effectively ensures the accurate proportion of raw materials for hydrogen peroxide preparation, thereby improving the quality of raw material addition during the hydrogen peroxide preparation process. At the same time, the time-delay alarm will promptly sound an alarm when the pumping time exceeds the set time when the raw material in the feeding tank reaches the specified liquid level, so that the staff can add raw materials to the raw material storage tank in a timely manner.

[0003] The utility model disclosed in CN222489976U is an intelligent proportioning and feeding device for soda ash and acetic acid. The device has a feed pipe at the top center of the silo, a filter assembly at the top of the feed pipe, a metering valve at the junction of the bottom of the feed pipe and the silo, a monitoring sensor on one side of the silo, a mixing assembly at the bottom of the silo, and a reaction vessel at the bottom of the mixing assembly. This device reduces the tediousness of manual operation, improves production efficiency, and ensures accurate proportioning.

[0004] However, the aforementioned raw material proportioning and addition device still has the following problems in actual use: it achieves quantitative proportioning and addition by setting up one or more chambers for raw material storage, but such addition device releases raw materials in a synchronous manner, and cannot add them in batches according to the required time, sequence and production conditions. The amount of raw materials in each chamber is also difficult to control. At the same time, some raw materials are prone to agglomeration and clumping due to storage environment and other issues, which affects the uniformity of mixing and preparation during addition and cannot improve the efficiency of production addition.

[0005] Therefore, we proposed a device for precise proportioning and adding raw materials for the production of benzo[a]hydroxyxamic acid, in order to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a precise proportioning and addition device for the production of benzohydroxyxamic acid. This addresses the problem that existing devices achieve quantitative proportioning and addition by setting up one or more chambers for raw material storage. However, such devices release raw materials synchronously, making it impossible to add them in batches according to the required time, sequence, and production conditions. Furthermore, the amount of raw materials in each chamber is difficult to control. Additionally, some raw materials are prone to agglomeration and clumping due to storage environment issues, which affects the uniformity of mixing and preparation during addition and fails to improve production addition efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a raw material precise proportioning and addition device for the production of benzohydroxyxamic acid, comprising an addition device body and a storage tank fixedly installed on the left and right sides inside the addition device body for storing the raw materials for the production of benzohydroxyxamic acid; It also includes: an addition mechanism is provided on the outside of the main body of the addition device, and the addition mechanism includes a partition plate, and the partition plate is slidably disposed at equal distances inside the left and right storage tanks; Among them, the equally spaced partition plates control the quantitative separation and addition of raw materials by sliding; The top of the adding device body is provided with a dredging mechanism, and the dredging mechanism includes a dredging bucket frame fixedly installed on the top surface of the adding device body.

[0008] Preferably, the adding mechanism includes a guide cone frame, which is fixedly installed on the top of the left and right storage tanks. The guide cone frame guides the raw materials placed inside the hopper, and the symmetrically arranged storage tanks have a hollow cylindrical structure to facilitate the addition of raw materials.

[0009] Preferably, the adding mechanism includes a positioning liner, which is fixedly installed on the front and rear sides of the main body of the adding device. A lifting screw is rotatably provided at the center of the inner part of the positioning liner via a bearing, and the outer wall of the lifting screw is threadedly connected to the inner end of the opening and closing bracket.

[0010] Preferably, the adding mechanism includes a solenoid valve plate, which is fixedly installed on the inner side of the front and rear opening and closing brackets at the end away from the adding device body. The solenoid valve plate and the power supply module are connected to each other through a transmission cable, and the power supply module is fixedly installed on the left and right sides of the outside of the adding device body.

[0011] Preferably, the outer end of the separator plate included in the adding mechanism slides through the left and right sides of the outside of the adding device body, and the outer end of the separator plate and the solenoid valve plate after being energized are mutually induced. By changing the direction of the solenoid valve plate being energized, an attraction and repulsion effect is formed between the solenoid valve plate and the separator plate, so that it slides inside the storage tank to realize material storage and feeding.

[0012] Preferably, the dredging mechanism includes dredging screens fixedly installed on the left and right sides inside the dredging bucket frame, and the top surface of the symmetrically arranged dredging screens is rotatably equipped with dredging rollers, and the interior of the symmetrically arranged dredging rollers is rotatably equipped with transmission arc rods through bearings.

[0013] Preferably, the guiding mechanism includes a guide groove, and a reciprocating screw is rotatably mounted inside the guide groove via a bearing. A guide slider is threaded through the outer wall of the reciprocating screw, and the guide slider is connected to the inner end of the transmission arc rod via an elastic slide rod.

[0014] Preferably, the guiding mechanism includes abutting protrusions, which are fixedly installed at equal intervals on the left and right sides above the guide groove. The bottom end of the abutting protrusions abuts against the moving transmission arc rod, thereby driving the transmission arc rod and the guiding roller to move downward to squeeze and guide the raw material on the top surface of the screen.

[0015] Preferably, the dredging mechanism includes a contact slide bar, and the contact slide bars are symmetrically installed in pairs on the left and right sides inside the dredging frame. The contact slide bars are connected to the dredging frame by a contact spring, and the contact slide bars contact the moving transmission arc rod, causing the contact slide bars to slide outward.

[0016] Preferably, the guiding mechanism includes a feeding ramp, which slides elastically on the left and right sides inside the guiding bucket in a symmetrical manner. The outer end of the feeding ramp is connected to the outer end of the contact slide rod by a traction steel cable. The contact slide rod slides outward, driving the feeding ramp to move inward to guide the residual raw materials and prevent leakage.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This raw material precise proportioning and addition device for the production of benzohydroxyxamic acid stores the raw materials in sections through the partition liner inside the storage tank, and controls the addition of raw materials in different areas by the movement of the solenoid valve plate. At the same time, the guide frame screens and guides the raw materials to avoid agglomeration and clumping of materials affecting production quality. The specific details are as follows: 1. The storage bin is equipped with equally spaced internal partitions to separate and store raw materials in different areas. The bottom partition slides into the interior of the storage bin, while the other partitions are open, allowing raw materials to be added and stored from bottom to top.

[0018] 2. After sufficient raw materials are stored in different areas inside the storage tank, the lifting screw drives the threaded opening and closing bracket and the solenoid valve plate to move from bottom to top. The power supply module supplies positive current to the inside of the solenoid valve plate, so that it and the dividing plate are magnetically repelled. This allows the dividing plates to slide into the storage tank one by one during the upward movement, and the storage amount of raw materials in different areas can be controlled and adjusted.

[0019] Furthermore, when adding raw materials, the process follows a bottom-up approach. A reverse current is supplied to the inside of the solenoid valve plate through the power supply module, causing it to be attracted to the separator plate by opposite magnetic forces. As it moves upward, it drives the corresponding separator plate to be attracted closer, so that the raw materials in the corresponding area can be added downward, improving controllability and the accuracy of the addition.

[0020] 3. The raw materials are fed into the guide frame above the guide screen. After the guide and filter are filtered, some of the agglomerated and lumpy raw materials remain above the guide screen. The reciprocating screw rotates, which drives the guide slider and the transmission arc rod to move. When the transmission arc rod moves, it drives the guide roller to rotate above the guide screen, which helps to crush the remaining raw materials before feeding them out.

[0021] Furthermore, when the guide slider drives the transmission arc rod to move inside the guide groove, the abutting protrusion squeezes and abuts the transmission arc rod, causing the transmission arc rod and the guide roller to move downwards and squeeze the raw material to achieve crushing, thus avoiding material residue and blockage.

[0022] 4. When the transmission arc rod and the guide roller move, they press against the sliding rod to make it slide outward, so as to tighten the traction steel cable, drive the feeding inclined plate connected to the other end to move into the interior of the guide frame, and push the raw material to the guide roller for crushing and guiding, so as to avoid residue and pollution.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-10 The present invention provides the following technical solution: Example 1: To address the existing problems in the production and feeding of benzohydroxyxamic acid, this example discloses the following technical solution: a precise proportioning and adding device for the production of benzohydroxyxamic acid, comprising an adding device body 1 and storage tanks 2 fixedly installed on the left and right sides inside the adding device body 1 for storing the raw materials for the production of benzohydroxyxamic acid; an adding mechanism is provided on the outside of the adding device body 1, and the adding mechanism includes a dividing plate 3, which is slidably disposed at equal distances inside the storage tanks 2 on the left and right sides; wherein, the equally spaced dividing plates 3 control the quantitative separation and addition of the raw materials by sliding.

[0027] The adding mechanism includes a guide cone 5, which is fixedly installed on the top of the left and right storage tanks 2. The guide cone 5 guides the raw materials placed inside the guide bucket 4. The symmetrically arranged storage tanks 2 have a hollow cylindrical structure, which facilitates the addition of raw materials. The adding mechanism includes a positioning liner 6, which is fixedly installed on the front and rear sides of the adding device body 1. A lifting screw 7 is rotatably installed at the center of the positioning liner 6 through a bearing. The outer wall of the lifting screw 7 is threadedly connected to the inner end of the opening and closing bracket 8.

[0028] The adding mechanism includes a solenoid valve plate 9, which is fixedly installed on the inner side of the end of the front and rear opening and closing brackets 8 away from the adding device body 1. The solenoid valve plate 9 is connected to the power supply module 10 through a transmission cable 11, and the power supply module 10 is fixedly installed on the left and right sides of the outside of the adding device body 1. The outer end of the partition plate 3 included in the adding mechanism slides through the left and right sides of the outside of the adding device body 1. The outer end of the partition plate 3 and the solenoid valve plate 9 after being energized are mutually induced. By changing the direction of the energization of the solenoid valve plate 9, an attraction and repulsion effect is formed between it and the partition plate 3, so that it slides inside the storage tank 2 to realize the storage and feeding of materials.

[0029] like Figures 3-4 As shown, when it is necessary to add raw materials in proportion through the storage tank 2 inside the main body 1 of the adding device, the storage tank 2 divides the space by the partition plates 3 arranged at equal intervals inside. During the storage process, the partition plate 3 at the bottom of the storage tank 2 is closed, while the other partition plates 3 above are open. Then, the raw materials after being guided are put into the corresponding storage tank 2 through the guide cone 5 by the guide bucket 4. The falling raw materials are blocked by the bottom partition plate 3 so that they are stored at the bottom inside the storage tank 2.

[0030] Furthermore, when it is necessary to separate and store raw materials, the power supply module 10 on the outside of the main body 1 of the adding device introduces positive current to the connected solenoid valve plate 9 through the transmission cable 11. At this time, the solenoid valve plate 9 and the outer end of the separating insert 3 are magnetically repelled, and the servo motor at the bottom of the positioning liner 6 drives the lifting screw 7 to rotate. The opening and closing bracket 8, which is threadedly connected to the lifting screw 7, is limited by the positioning liner 6 so that the opening and closing bracket 8 drives the solenoid valve plate 9 to move upward. The separating insert 3 located at the bottom is located inside the storage tank 2 and is not affected. After the solenoid valve plate 9 continues to move upward to the area divided by the separating insert 3 to store the raw materials, the corresponding separating insert 3 is moved into the storage tank 2 by the solenoid valve plate 9. The storage tank 2 separates the raw materials by the separating insert 3, and the quantity of raw materials after separation is controlled by the closing time of the separating insert 3.

[0031] When adding raw materials into the storage tank 2, the opening and closing bracket 8 moves the solenoid valve plate 9 to the lowest initial position. The power supply module 10 introduces reverse current to the connected solenoid valve plate 9 through the transmission cable 11, so that the solenoid valve plate 9 and the outer end of the separator plate 3 are attracted by opposite magnetism. When the opening and closing bracket 8 moves the solenoid valve plate 9 from bottom to top, it drives the corresponding separator plate 3 to slide outward, thereby adding the separated raw materials downward, improving the convenience and accuracy of adding.

[0032] Example 2: To solve the problems existing in the production and feeding of benzoyl hydroxamic acid, this example discloses the following technical solution: The top of the adding device body 1 is provided with a guiding mechanism, and the guiding mechanism includes a guiding bucket 4 fixedly installed on the top surface of the adding device body 1; the guiding mechanism includes guiding screens 23 fixedly installed on the left and right sides inside the guiding bucket 4, and the top surface of the symmetrically arranged guiding screens 23 is rotatably provided with guiding rollers 12, and the interior of the symmetrically arranged guiding rollers 12 is rotatably provided with transmission arc rods 13 through bearings; the guiding mechanism includes a guide groove 14, and the interior of the guide groove 14 is rotatably provided with a reciprocating screw 15 through bearings, and the outer wall of the reciprocating screw 15 is threaded through a guide slider 16, and the guide slider 16 and the inner end of the transmission arc rod 13 are connected to each other through an elastic slide rod 17.

[0033] The guiding mechanism includes abutting protrusions 18, which are fixedly installed at equal intervals on the left and right sides above the guide chute 14. The bottom ends of the abutting protrusions 18 abut against the moving transmission arc rod 13, causing the transmission arc rod 13 and the guiding roller 12 to move downwards and squeeze the raw material on the top surface of the guiding screen 23. The guiding mechanism also includes abutting slide rods 19, which are symmetrically installed in pairs on the left and right sides inside the guiding bucket frame 4. The abutting slide rods 19 and the guiding bucket frame 4 are connected by abutting... The contact springs 20 are interconnected, and the contact slide bar 19 contacts the moving transmission arc bar 13, causing the contact slide bar 19 to slide outward. The guiding mechanism includes a feeding sloping plate 21, which slides elastically on the left and right sides inside the guiding bucket 4 in a symmetrical manner. The outer end of the feeding sloping plate 21 is connected to the outer end of the contact slide bar 19 through a traction steel cable 22. The contact slide bar 19 slides outward, causing the feeding sloping plate 21 to move inward to guide the residual raw materials and prevent leakage.

[0034] like Figures 5-6 , Figure 8 As shown, when guiding raw materials, different raw materials are fed into the guiding bucket 4, which can process multiple raw materials at the same time. The reciprocating screw 15 installed inside the guiding bucket 4 is controlled by a servo motor to drive the threaded guide slider 16 to move inside the guide groove 14. At the same time, the transmission arc rod 13 connected to the left and right sides of the guide slider 16 and the guiding roller 12 through the elastic slide rod 17 are driven to move back and forth in the direction of reciprocating motion, so as to crush and guide the raw materials remaining above the guiding screen 23, and avoid the raw materials from clogging due to agglomeration and clumping.

[0035] like Figures 5-6As shown, when the guide slider 16 drives the transmission arc rod 13 to reciprocate inside the guide groove 14, the transmission arc rod 13 contacts the abutting protrusions 18 arranged at equal distances, causing the transmission arc rod 13 to drive the guide roller 12 to move downward and squeeze and crush the raw material above the guide screen 23, so as to improve the guiding effect and the efficiency of material storage and addition.

[0036] like Figure 7 , Figures 9-10 As shown, during the movement of the guide roller 12 and the transmission arc rod 13 inside the guide frame 4, they approach and press against the sliding rod 19, causing the sliding rod 19 to move outward and drive the traction cable 22 to tighten. The other end of the traction cable 22 drives the fixedly connected feeding inclined plate 21 to slide inward, thereby pushing the residual raw material to the side close to the guide roller 12. The guide roller 12 then crushes and feeds the raw material, avoiding pollution caused by residue in subsequent work.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
