Description

Technical Field

[0001] This utility model relates to the field of chemical reagent mixing technology, specifically to a raw material mixing device for chemical reagents. Background Technology

[0002] In the production and experimentation of chemical reagents, raw material mixing is one of the key processes, as its uniformity directly affects the purity, performance, and subsequent experimental or production results of the reagents. Existing chemical reagent raw material mixing equipment has several shortcomings:

[0003] Firstly, most equipment has a simple stirring structure, using only a single-layer stirring rod for mixing, which easily leads to material stratification. This is especially true for reagent materials with large density differences, making it difficult to guarantee the uniformity of mixing.

[0004] Secondly, the equipment lacks an effective anti-corrosion protection structure. Most chemical reagents are corrosive, and long-term use can easily cause corrosion inside the tank, which not only shortens the service life of the equipment, but may also cause corrosion products to mix into the reagents, affecting the purity of the reagents.

[0005] Third, the sealing performance of the feeding port is poor. Some equipment cannot achieve a reliable seal after feeding, which can easily lead to reagent volatilization and leakage, resulting in waste of raw materials and potential harm to the health of operators and the environment.

[0006] Fourth, raw materials tend to remain at the bottom of the equipment, making it difficult to completely discharge them during the discharge process. This not only wastes raw materials but may also cause cross-contamination during the next mixing process.

[0007] Fifth, some equipment lacks overall stability and is prone to shaking during the stirring process, which affects the normal operation of the equipment and the mixing effect. Therefore, a raw material mixing device for chemical reagents is proposed to solve the above-mentioned problems. Utility Model Content

[0008] (a) Technical problems to be solved

[0009] To address the shortcomings of existing technologies, this utility model provides a chemical reagent raw material mixing device, which has the advantages of high mixing uniformity, excellent corrosion resistance, reliable feeding and sealing, low discharge residue, and strong overall stability. It solves the problems of existing mixing devices, such as uneven mixing due to simple mixing structure, lack of internal corrosion protection leading to easy corrosion, poor sealing of the feeding port leading to reagent volatilization and leakage, excessive raw material residue at the bottom causing waste and cross-contamination, and insufficient equipment operation stability and easy shaking.

[0010] (II) Technical Solution

[0011] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a raw material mixing device for chemical reagents, including a storage mechanism, wherein a mixing mechanism extending into the storage mechanism is provided on the top of the storage mechanism.

[0012] The mixing mechanism includes a motor, which is fixedly connected to the top of the storage mechanism. The output end of the motor is fixedly connected to a main shaft that extends into the storage mechanism. Two mounting rings, symmetrically distributed vertically, are fixedly connected to the outer side of the main shaft. Four stirring rods, equidistantly distributed in a ring, are fixedly connected to the outer side of each of the two mounting rings. Multiple stirring spokes, equidistantly distributed longitudinally, are fixedly connected between the lower stirring rod and the upper stirring rod, which are adjacent to each other at a 90-degree angle. The multiple stirring spokes are arranged in an arc-shaped incline. An inclined discharge scraper is fixedly connected to the bottom of each of the four lower stirring rods.

[0013] The beneficial effects of this utility model are as follows: The symmetrically distributed mounting rings and stirring rods in the mixing mechanism, along with the arc-shaped inclined stirring spokes connecting the upper and lower stirring rods, form a three-dimensional stirring structure. This allows for thorough mixing of raw materials at different heights and positions within the storage mechanism, effectively preventing material stratification and improving mixing uniformity. The inclined discharge scraper at the bottom of the lower stirring rod scrapes the bottom of the storage mechanism during mixing, reducing material residue and assisting the material in moving towards the discharge port for complete discharge. The overall structure is rationally designed, easy to operate, and meets the high precision and reliability requirements for mixing chemical reagent raw materials, offering advantages such as uniform mixing, thorough discharge, and ease of use.

[0014] The raw material mixing equipment for this chemical reagent has the advantages of high mixing uniformity, excellent corrosion resistance, reliable feeding and sealing, low discharge residue, and strong overall stability.

[0015] Based on the above technical solution, the present invention can be further improved as follows.

[0016] Furthermore, the storage mechanism includes a tank, the top of which is provided with a removable cover plate, the motor is fixedly connected to the top of the cover plate, and an observation window is provided on the outside of the tank.

[0017] The beneficial effects of adopting the above-mentioned further solutions are that the tank in the storage mechanism provides a closed mixing space for the raw materials, avoiding the introduction of external impurities and the evaporation of reagents; the removable cover facilitates the maintenance and cleaning of the tank interior and mixing mechanism in the later stages, reducing the difficulty of equipment maintenance; the motor is fixed on the cover, and the mixing mechanism can be removed simultaneously when the cover is removed, further improving the convenience of maintenance; the observation window on the outside of the tank allows operators to observe the mixing status and liquid level of the raw materials in real time, and can grasp the mixing progress without opening the cover, improving the convenience of operation, while avoiding reagent evaporation or contamination caused by frequent opening of the cover.

[0018] Furthermore, the bottom of the storage mechanism is fixedly connected to three support legs that are distributed in a ring at equal intervals, and the bottom of each of the three support legs is fixedly connected to a base that is arranged in a trapezoidal platform.

[0019] The beneficial effects of adopting the above-mentioned further solution are that the three support legs distributed in a ring at equal distances provide stable support for the storage mechanism and the entire equipment, making the equipment evenly stressed; the trapezoidal base at the bottom of the support legs increases the contact area with the ground, further improving the overall stability of the equipment, effectively reducing the vibration and shaking caused by stirring during the operation of the mixing mechanism, ensuring that the equipment is always in a stable operating state during the mixing process, and avoiding the impact of equipment shaking on mixing accuracy or reagent leakage.

[0020] Furthermore, a feeding mechanism is provided on the top of the cover plate, and anti-corrosion cylinder sleeves are embedded in the bottom of the cover plate and the inner side of the tank. A discharge valve pipe communicating with the inside of the tank is fixedly connected to the outer side of the tank.

[0021] The beneficial effects of adopting the above-mentioned further solutions are that the feeding mechanism at the top of the cover plate provides a dedicated channel for adding raw materials, facilitating precise feeding while ensuring the sealing of the feeding process; the anti-corrosion cylinder liner at the bottom of the cover plate and inside the tank is made of chemically resistant materials such as polytetrafluoroethylene or corrosion-resistant alloys, which can effectively isolate chemical reagents from direct contact with the cover plate and tank body, preventing equipment corrosion, extending equipment service life, and preventing corrosion products from mixing into the reagents, ensuring reagent purity; the discharge valve pipe on the outside of the tank facilitates control of the discharge speed and discharge volume, which can be flexibly adjusted according to needs, and the tank can be sealed when the valve is closed, meeting the requirements of a closed environment during the mixing process.

[0022] Furthermore, the feeding mechanism includes a feeding port, which is located on the top of the cover plate. A fixing pin is fixedly connected to the top of the cover plate and located outside the feeding port. A sealing plate that is fastened to the outside of the fixing pin is rotatably connected to the outside of the fixing pin and is adapted to the feeding port. A locking strip is fixedly connected to the top of the cover plate and located outside the sealing plate and is adapted to the sealing plate. A handle located on the opposite side of the fixing pin is fixedly connected to the top of the sealing plate.

[0023] The beneficial effects of adopting the above-mentioned further solution are as follows: the feeding port in the feeding mechanism provides a channel for adding raw materials, and its size can be set according to the discharge port of common raw material containers to facilitate the smooth pouring of raw materials; the fixed pin realizes the rotational connection of the sealing plate, so that the sealing plate can rotate around the fixed pin, making it easy to open or close the feeding port; the sealing plate adapted to the feeding port can completely cover the feeding port when closed, ensuring the sealing performance of the feeding port and preventing reagent evaporation or the entry of external impurities; the locking strip can fix the sealing plate after it is closed, preventing the sealing plate from loosening due to equipment vibration during the stirring process, further improving the sealing reliability; the handle on the top of the sealing plate makes it easy for the operator to manually rotate the sealing plate, improving the convenience of operation, and the opening and closing operation of the feeding port can be completed without the need for additional tools.

[0024] Furthermore, the locking strip has an L-shaped cross-section and is used to fix the sealing plate after it is closed. The sealing plate is disc-shaped and can be rotated out from inside the locking strip with the fixing pin as the center.

[0025] The advantages of adopting the above-mentioned further solution are that the L-shaped locking strip can limit the top of the sealing plate in its horizontal part, and the longitudinal part is fixedly connected to the cover plate to form a stable fixing structure. It can reliably fix the sealing plate after closing, prevent the sealing plate from loosening upward or shifting laterally, and ensure the sealing effect. The disc-shaped sealing plate is more compatible with common circular feeding ports, has a larger sealing area, and a better sealing effect. The setting that the sealing plate can be rotated out from inside the locking strip around the fixing pin makes the opening and closing operation more flexible. The operator can easily rotate the sealing plate out of the locking strip's limiting range by holding the handle to open the feeding port. The operation process is simple and efficient. At the same time, when screwed in, it can accurately cooperate with the locking strip to achieve fixation, taking into account both convenience and reliability. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] In the embodiments, by Figure 1-4 The present invention provides a raw material mixing device for a chemical reagent, comprising a storage mechanism 1, wherein a mixing mechanism 2 extending into the storage mechanism 1 is provided on the top of the storage mechanism 1.

[0033] The mixing mechanism 2 includes a motor 201, which is fixedly connected to the top of the storage mechanism 1. The output end of the motor 201 is fixedly connected to a main shaft 202 that extends into the storage mechanism 1. Two mounting rings 203 are fixedly connected to the outside of the main shaft 202 and are symmetrically distributed vertically. Four stirring rods 204 are fixedly connected to the outside of each of the two mounting rings 203 and are distributed in a ring at equal intervals. Multiple stirring spokes 205 are fixedly connected between the lower stirring rod 204 and the upper stirring rod 204 at a 90-degree angle. The multiple stirring spokes 205 are arranged in an arc-shaped inclined manner. The bottom of each of the four lower stirring rods 204 is fixedly connected to an inclined discharge scraper 206.

[0034] The storage mechanism 1 includes a tank 101, a removable cover plate 102 is provided on the top of the tank 101, a motor 201 is fixedly connected to the top of the cover plate 102, and an observation window 103 is provided on the outside of the tank 101.

[0035] The tank 101 in the storage mechanism 1 provides a closed mixing space for the raw materials, preventing the ingress of external impurities and the evaporation of reagents. The removable cover 102 facilitates the maintenance and cleaning of the interior of the tank 101 and the mixing mechanism 2, reducing the difficulty of equipment maintenance. The motor 201 is fixed on the cover 102, and the mixing mechanism 2 can be removed simultaneously when the cover 102 is removed, further improving the convenience of maintenance. The observation window 103 on the outside of the tank 101 allows operators to observe the mixing status and liquid level of the raw materials in real time, and can grasp the mixing progress without opening the cover 102, improving the convenience of operation, while avoiding reagent evaporation or contamination caused by frequent opening of the cover.

[0036] The bottom of the storage mechanism 1 is fixedly connected to three support legs 3 that are distributed in a ring at equal intervals, and the bottom of each of the three support legs 3 is fixedly connected to a base 4 that is set in a trapezoidal platform.

[0037] Three support legs 3, arranged in a ring at equal intervals, provide stable support for the storage mechanism 1 and the entire equipment, ensuring that the equipment is subjected to uniform force. The trapezoidal base 4 at the bottom of the support legs 3 increases the contact area with the ground, further improving the overall stability of the equipment and effectively reducing the vibration and shaking caused by stirring when the mixing mechanism 2 is working. This ensures that the equipment is always in a stable operating state during the mixing process, avoiding the impact of equipment shaking on mixing accuracy or reagent leakage.

[0038] The top of the cover plate 102 is provided with a feeding mechanism 5, and the bottom of the cover plate 102 and the inner side of the tank body 101 are both fitted with anti-corrosion cylinder sleeves 6. The outer side of the tank body 101 is fixedly connected with a discharge valve pipe 7 that communicates with the inside of the tank body 101.

[0039] The feeding mechanism 5 at the top of the cover plate 102 provides a dedicated channel for adding raw materials, facilitating precise feeding while ensuring the sealing of the feeding process. The anti-corrosion cylinder sleeve 6 at the bottom of the cover plate 102 and the inner side of the tank 101 is made of chemically resistant material, such as polytetrafluoroethylene or corrosion-resistant alloy, which can effectively isolate chemical reagents from direct contact with the cover plate 102 and the tank 101 body, preventing equipment corrosion, extending equipment service life, and preventing corrosion products from mixing into the reagents, thus ensuring reagent purity. The discharge valve pipe 7 on the outside of the tank 101 facilitates control of the discharge speed and discharge volume, which can be flexibly adjusted according to needs. At the same time, closing the valve can achieve sealing of the tank 101, meeting the requirements of a closed environment during the mixing process.

[0040] The feeding mechanism 5 includes a feeding port 501, which is located on the top of the cover plate 102. A fixing pin 502 located outside the feeding port 501 is fixedly connected to the top of the cover plate 102. A sealing plate 503 that is fastened to the outside of the fixing pin 502 is rotatably connected to the outside of the fixing pin 502. The sealing plate 503 is adapted to the feeding port 501. A locking strip 504 located outside the sealing plate 503 is fixedly connected to the top of the cover plate 102. The locking strip 504 is adapted to the sealing plate 503. A handle 505 located on the opposite side of the fixing pin 502 is fixedly connected to the top of the sealing plate 503.

[0041] The feeding port 501 in the feeding mechanism 5 provides a channel for adding raw materials. Its size can be set according to the discharge port of common raw material containers to facilitate the smooth pouring of raw materials. The fixed pin 502 realizes the rotational connection of the sealing plate 503, so that the sealing plate 503 can rotate around the fixed pin 502, which facilitates opening or closing the feeding port 501. When the sealing plate 503, which is adapted to the feeding port 501, is closed, it can completely cover the feeding port 501 to ensure the sealing performance of the feeding port 501 and prevent reagent evaporation or the entry of external impurities. The locking strip 504 can fix the sealing plate 503 after it is closed to prevent the sealing plate 503 from loosening due to equipment vibration during the stirring process, and further improve the sealing reliability. The handle 505 on the top of the sealing plate 503 makes it easy for the operator to manually rotate the sealing plate 503, improving the convenience of operation, and the opening and closing operation of the feeding port 501 can be completed without the need for additional tools.

[0042] The locking strip 504 has an L-shaped cross-section and is used to fix the closed sealing plate 503. The sealing plate 503 is disc-shaped and can be rotated out from the locking strip 504 with the fixing pin 502 as the center.

[0043] The L-shaped locking strip 504 has a lateral portion that limits the top of the sealing plate 503, while its longitudinal portion is fixedly connected to the cover plate 102, forming a stable fixing structure. This reliably fixes the sealed plate 503 after it is closed, preventing it from loosening upwards or shifting laterally, thus ensuring a good sealing effect. The disc-shaped sealing plate 503 is more compatible with the common circular feeding port 501, providing a larger sealing area and a better sealing effect. The design allows the sealing plate 503 to be rotated out of the locking strip 504 around the fixing pin 502, making the operation more flexible. Operators can easily rotate the sealing plate 503 out of the limiting range of the locking strip 504 by holding the handle 505 to open the feeding port 501. The operation is simple and efficient, and when screwed in, it can precisely cooperate with the locking strip 504 to achieve fixation, balancing convenience and reliability.

[0044] Working principle:

[0045] Step 1: Equipment preparation and feeding operation. First, check the status of each component of the equipment to ensure that the discharge valve pipe 7 is closed and the anti-corrosion cylinder liner 6 is undamaged. Use the handle 505 to unscrew the sealing plate 503 around the fixing pin 502 to release the locking strip 504. Open the feeding port 501 and add the chemical reagent raw materials to be mixed into the tank 101 through the feeding port 501 in sequence according to the preset ratio. After feeding is completed, screw the sealing plate 503 back to its original position so that the sealing plate 503 is fastened on the feeding port 501 and the edge of the sealing plate 503 is inserted into the L-shaped limiting structure of the locking strip 504 to achieve sealing and fixing of the feeding port 501.

[0046] Step 2: Start the mixing mechanism 2 for stirring. Connect the power supply to the motor 201. After the motor 201 starts, it drives the main shaft 202 to rotate. The main shaft 202 drives the two outer upper and lower mounting rings 203 to rotate synchronously. The mounting rings 203 drive the outer stirring rods 204 to rotate. The upper and lower stirring rods 204 stir the raw materials in the upper and lower areas of the tank 101 respectively. At the same time, the arc-shaped inclined stirring spokes 205 between the upper and lower stirring rods 204 rotate with the stirring rods 204, and perform horizontal and vertical double stirring of the raw materials between the two layers of stirring rods 204, breaking the tendency of raw material stratification and achieving uniform mixing of raw materials. During the stirring process, the operator can observe the mixing status of the internal raw materials in real time through the observation window 103 on the outside of the tank 101 to judge whether the mixing has achieved the expected effect.

[0047] Step 3: Discharge operation and equipment cleaning. After confirming through the observation window 103 that the raw materials are evenly mixed, turn off the motor 201, and the mixing mechanism 2 stops working. Slowly open the valve of the discharge valve pipe 7. The mixed reagent inside the tank 101 is discharged through the discharge valve pipe 7 under the action of gravity. At the same time, the motor 201 can be briefly restarted again to make the discharge scraper 206 at the bottom of the stirring rod 204 rotate and scrape the bottom of the tank 101 to push the remaining reagent at the bottom to the discharge valve pipe 7, ensuring that the reagent is completely discharged. After the discharge is completed, close the discharge valve pipe 7. If the next mixing or long-term storage is required, the cover plate 102 can be removed to clean the anti-corrosion cylinder liner 6 inside the tank 101, the stirring rod 204 of the mixing mechanism 2, the stirring spokes 205 and the discharge scraper 206. After cleaning, reassemble the cover plate 102 and wait for the next use.
