Description

Technical Field

[0001] This utility model relates to the field of calcium oxide storage technology, and in particular to a calcium oxide storage device. Background Technology

[0002] Calcium oxide, also known as quicklime, is a common inorganic compound. It is widely used in the manufacture of calcium carbide, soda ash, and bleaching powder. It is the main raw material for the production of calcium hydroxide and various calcium compounds. As an alkaline oxide, calcium oxide has the property of absorbing water and moisture, and is not easy to store for a long time.

[0003] Existing calcium oxide storage containers typically have good sealing properties, isolating calcium oxide from the outside air. To further improve the moisture-proof capability of the calcium oxide in the container, the interior of the container is usually divided into two interconnected chambers. One chamber is used to store calcium oxide, and the other chamber is used to store desiccant. The desiccant absorbs moisture from the air in both chambers, thus preventing the calcium oxide from absorbing water and becoming damp, and improving the storage effect of calcium oxide.

[0004] Existing calcium oxide storage containers capable of absorbing moisture from the air typically have an inlet and an outlet at the top and bottom of the chamber used to store the desiccant, respectively. Valves are installed at the inlet and outlet to allow the desiccant to be added into the chamber through the inlet and discharged through the outlet. However, after absorbing moisture, the desiccant may clump or even harden. Clumped or hardened desiccant is difficult to discharge from the outlet, thus affecting the efficiency and convenience of desiccant replacement. Utility Model Content

[0005] To address the technical problems in the existing calcium oxide storage containers with the ability to absorb moisture from the air, where the desiccant becomes caked or caking and is difficult to discharge from the outlet, and the desiccant is difficult to replace, this utility model provides a calcium oxide storage device.

[0006] The technical solution of this utility model is as follows:

[0007] This utility model provides a calcium oxide storage device, including an outer shell, an inner shell fixedly disposed inside the outer shell, a first chamber disposed in the inner shell, and a second chamber disposed between the outer shell and the inner shell. The inner shell has several first vent holes, and the first and second chambers are connected through the first vent holes. The second chamber has an upper opening structure, and a desiccant rack is detachably installed inside the second chamber. The top of the desiccant rack seals the upper opening of the second chamber. The desiccant rack has several placement slots for placing desiccant. The desiccant is placed on the desiccant rack. Due to the detachable design of the desiccant rack, after prolonged use, the desiccant rack can be directly pulled out from the second chamber, allowing for the direct removal of clumped or hardened desiccant, facilitating desiccant replacement. This eliminates the need for a desiccant discharge port, effectively preventing clogging of the discharge port by the desiccant.

[0008] Preferably, the desiccant placement rack includes a frame body, with placement slots disposed on the frame body. The desiccant is placed in the placement slots of the frame body in a classified manner, which can realize the orderly distribution of the desiccant, prevent the desiccant from accumulating in the second chamber, and improve the drying efficiency. At the same time, the frame structure is easy to disassemble and install as a whole, which facilitates the replacement of the desiccant.

[0009] Preferably, the frame includes an installation part, which is a ring-shaped plate structure. A drying part is fixedly connected to the lower surface of the installation part. The drying part and the installation part are coaxially arranged. The desiccant placement rack cooperates with the inner wall of the second chamber to form a ring-shaped drying area, which expands the contact area between the desiccant and the air and enhances the drying effect. The drying part is inserted into the second chamber to facilitate the replacement of the desiccant. Several placement slots are evenly opened on the drying part along its circumference, so that humid air can be adsorbed by the desiccant from multiple directions and avoid the formation of drying dead corners.

[0010] Preferably, a support is fixedly provided at the upper opening of the second chamber, and the mounting part overlaps with the support and is bolted to facilitate the installation and positioning of the desiccant placement rack. A sealing ring is provided between the support and the mounting part to effectively improve the sealing effect and prevent outside air from entering the second chamber.

[0011] Preferably, the drying section has several second vent holes that are connected to the interior of the placement tank, allowing the desiccant in the placement tank to come into contact with the air in the second chamber at multiple angles, accelerating the entry of humid air into the placement tank and contacting the desiccant, thereby improving the moisture absorption efficiency.

[0012] Preferably, the installation part is detachably connected to a breathable partition, and the drying part is inserted into the breathable partition. The breathable partition is evenly provided with several third vent holes, which can block the opening side of the placement tank to prevent the desiccant in the placement tank from falling out, while ensuring air circulation.

[0013] Preferably, the device also includes an inlet and an outlet communicating with the first chamber. The inlet is fixedly located at the top of the outer shell, and the outlet is fixedly located at the bottom of the outer shell. The bottom of the outer shell is also fixedly provided with a support leg to improve the overall stability of the calcium oxide storage device.

[0014] Preferably, a motor is fixedly installed on the outer shell, and a stirring rod is rotatably installed in the first chamber. The stirring rod is connected to the output shaft of the motor, and several blades are fixedly installed on the stirring rod to prevent the calcium oxide in the first chamber from clumping or compacting due to long-term storage, thus maintaining its loose state and facilitating smooth discharge during material discharge.

[0015] As can be seen from the above technical solutions, the advantages of this utility model are:

[0016] 1. The desiccant rack is equipped with several slots for placing desiccant. The desiccant is placed on the desiccant rack. With the desiccant rack being detachable, after long-term use, the desiccant rack can be directly pulled out from the second chamber, and the clumped or hardened desiccant can be directly removed, which facilitates the replacement of desiccant. The desiccant discharge port is eliminated, effectively avoiding the clogging of the discharge port by desiccant.

[0017] 2. Several placement slots are evenly distributed around the drying section, which can achieve orderly distribution of desiccant, avoid the desiccant from piling up in the second chamber, and allow humid air to be adsorbed by the desiccant from multiple directions, avoiding drying dead zones and improving drying efficiency. At the same time, the desiccant placement rack cooperates with the inner wall of the second chamber to form a ring-shaped drying area, expanding the contact area between the desiccant and the air and enhancing the drying effect.

Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0027] Example 1

[0028] In a typical embodiment of this utility model, such as Figures 1-3As shown, a calcium oxide storage device is proposed, comprising: an outer shell 1, an inner shell 2, a first chamber 3, a second chamber 4, and a desiccant rack 9. The inner shell 2 is fixedly disposed inside the outer shell 1, and the first chamber 3 is disposed within the inner shell 2 for storing calcium oxide. The second chamber 4 is disposed between the outer shell 1 and the inner shell 2, and the second chamber 4 has an opening at the top. The desiccant rack 9 is installed into the second chamber 4 through the opening at the top, and the desiccant rack 9 seals the opening at the top of the second chamber 4 to prevent external gas from entering the second chamber 4 through the opening after the desiccant rack 9 is installed. The desiccant rack 9 is provided with several desiccant placement devices. The desiccant placement tank 13; the inner shell 2 is provided with several first vent holes 5, the first chamber 3 and the second chamber 4 are connected through the first vent holes 5, the air in the first chamber 3 can enter the second chamber 4 through the first vent holes 5, and be dried by the desiccant in the second chamber 4 to prevent the calcium oxide in the first chamber 3 from absorbing water and becoming damp; the calcium oxide storage device also includes a feed port 6 and a discharge port 7, the feed port 6 is fixedly set at the top of the outer shell 1, and the discharge port 7 is fixedly set at the bottom of the outer shell 1. Both the feed port 6 and the discharge port 7 are connected to the first chamber 3, and control valves are installed on both the feed port 6 and the discharge port 7 to control the opening and closing of the feed port 6 and the discharge port 7.

[0029] The top of the desiccant rack 9 is detachably connected to the outer shell 1. The desiccant is placed on the desiccant rack 9. After long-term use, the desiccant rack 9 can be directly pulled out from the second chamber 4, thereby removing the clumped or hardened desiccant. This facilitates the replacement of the desiccant and eliminates the need for a desiccant discharge port, effectively preventing the desiccant from clogging the discharge port.

[0030] In this embodiment, both the outer shell 1 and the inner shell 2 are cylindrical structures. The inner shell 2 is coaxially arranged with the outer shell 1. The first vent 5 is evenly arranged along the circumference of the inner shell 2 to realize the connection between the first chamber 3 and the second chamber 4. Several support legs 8 are fixedly provided at the bottom of the outer shell 1 to support the entire storage device.

[0031] The desiccant rack 9 includes a frame 10, such as Figure 2 As shown, the frame 10 includes a mounting section 11 and a drying section 12. The mounting section 11 is an annular plate structure, which is used to detachably connect to the outer shell 1 and support the overall frame 10, while also sealing the upper opening of the second chamber 4. The drying section 12 is an annular structure, and the drying section 12 is fixedly installed on the lower surface of the mounting section 11 by welding. The drying section 12 is coaxially arranged with the mounting section 11. The outer diameter of the drying section 12 is smaller than the outer diameter of the mounting section 11, and the inner diameter of the drying section 12 is larger than the inner diameter of the second chamber 4. Several placement grooves 13 are evenly opened on the drying section 12 along its circumference for placing desiccant.

[0032] The mounting part 11 has a plurality of mounting holes spaced around its circumference for detachable connection to the outer casing 1 by means of bolts. Figure 5 As shown, a support part 22 is welded and fixed on the outer shell 1. The support part 22 is located at the upper opening of the second chamber 4 to support the mounting part 11. The mounting part 11 is connected to the support part 22 by bolts. The setting of the support part 22 not only ensures that the upper surface of the mounting part 11 is flush with the surface of the outer shell 1, improving the aesthetics after installation, but also extends the contact path between the second chamber 4 and the outside world, improving the sealing ability.

[0033] To further improve the sealing capability, a sealing ring 23 can be fixedly installed between the support part 22 and the mounting part 11, that is, on the upper surface of the support part 22 and the lower surface of the mounting part 11, so as to improve the connection sealing between the support part 22 and the mounting part 11; in other embodiments, a lifting lug is also fixedly installed on the upper surface of the mounting part 11 to facilitate the lifting and installation of the entire frame 10.

[0034] like Figure 2 As shown, the placement slot 13 is opened on the drying section 12 of the frame 10. The placement slot 13 has an open structure at one end for placing the desiccant. In order to increase the contact area between the desiccant and the air and improve the drying effect, the drying section 12 is also provided with a number of second vent holes 14. The second vent holes 14 are connected to the interior of the placement slot 13, so that the air in the second chamber 4 can not only contact the desiccant from the open side of the placement slot 13, but also enter the placement slot 13 through the second vent holes 14 located on the opposite side of the open side of the placement slot 13 to contact the desiccant in the placement slot 13.

[0035] The desiccant rack 9 also includes a breathable partition 15, such as... Figure 3 and Figure 4 As shown, the venting baffle 15 is an annular filter cartridge structure. The top of the venting baffle 15 is provided with an installation groove 24 for the insertion of the drying section 12. The bottom of the venting baffle 15 is sealed. Several third vent holes 18 are provided on both the inner and outer walls of the venting baffle 15 to allow gas to pass through. The venting baffle 15 is sleeved on the outside of the drying section 12 to block the opening side of the placement groove 13 and prevent the desiccant in the placement groove 13 from falling out. The depth of the venting baffle 15 is the same as the length of the drying section 12.

[0036] The top of the breathable partition 15 is fixed with an ear plate 16 by welding. The ear plate 16 is a ring plate structure. Several bolt holes 17 are provided on the ear plate 16 along its circumferential direction for bolt installation. The ear plate 16 is connected to the mounting part 11 by bolts, so as to realize the detachable connection between the breathable partition 15 and the frame 10.

[0037] It is understood that a number of threaded holes are provided on the lower surface of the mounting part 11 at intervals along its circumference for installation with bolts. The number and position of the threaded holes are the same as those of the bolt holes 17 and correspond one-to-one.

[0038] The calcium oxide storage device is also equipped with a stirring mechanism for stirring the calcium oxide in the first chamber 3. Specifically, a motor 19 is fixedly installed at the top of the outer shell 1, and a stirring rod 20 is provided in the first chamber 3. The stirring rod 20 is vertically arranged in the first chamber 3, and the upper end of the stirring rod 20 is fixedly connected to the output shaft of the motor 19 through a coupling. Several blades 21 are fixedly arranged on the stirring rod 20 along its circumferential and axial directions. The motor 19 can drive the blades 21 to rotate around the shaft through the stirring rod 20, so as to use the blades 21 to stir the calcium oxide in the first chamber 3, which facilitates the discharge of calcium oxide.

[0039] The specific working principle is as follows:

[0040] Place the desiccant in the placement slot 13 on the drying section 12, and insert the drying section 12 containing the desiccant into the venting partition 15, aligning the bolt holes 17 on the ear plate 16 with the threaded holes on the mounting section 11, and tighten the bolts to complete the assembly of the desiccant placement rack 9; hoist the assembled desiccant placement rack 9 above the outer shell 1, inserting the drying section 12 and the venting partition 15 into the second chamber 4, so that the mounting section 11 abuts against the support section 22, and use bolts to secure the mounting section 11 to the support section 22. The support parts 22 are tightened and fixed together. During the storage of calcium oxide, the air in the first chamber 3 enters the second chamber 4 through the first vent 5 and enters the vent partition 15 through the third vent 18. Some of the air directly contacts the desiccant through the opening of the placement slot 13, and the other part of the air contacts the desiccant in the placement slot 13 through the second vent 14. When the desiccant needs to be replaced, the bolts between the mounting part 11 and the support part 22 are removed, and the desiccant placement rack 9 can be directly pulled out for replacement. The desiccant replacement is convenient.

[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
