Detailed Embodiment

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0025] As Figures 1-5 shown, an embodiment of the present utility model discloses a boron trichloride tailing treatment device, including a cuboid refrigerated box body 1, and a storage tank 2 containing boron trichloride tailings is disposed inside the refrigerated box body 1;

[0026] A refrigerator (not shown in the drawings) is embedded and installed on an outer side wall of the refrigerated box body 1. The refrigerator is fixedly embedded and installed on an outer surface of one side of the refrigerated box body 1, and the operation and stop of the refrigerator are controlled by an external control device. Therefore, the temperature inside the refrigerated box body can be reduced by the operation of the refrigerator, ensuring that boron trichloride does not reach its boiling point, avoiding quality changes of boron trichloride, and ensuring the safety of the boron trichloride treatment process.

[0027] A shock-absorbing base 3 is installed at the bottom of the storage tank 2, a bottom protective sleeve 30 is fixedly installed on the upper surface of the shock-absorbing base 3, the storage tank 2 is inserted into the inside of the bottom protective sleeve 30, and a tank body protective sleeve 31 is detachably installed on the top of the bottom protective sleeve 30, and the tank body protective sleeve 31 is sleeved on the outer surface of the storage tank 2;

[0028] In this embodiment, through the cooperative setting of the bottom protective sleeve and the tank body protective sleeve, the entire storage tank can be well protected, and it is not easy for the storage tank to be damaged due to impact.

[0029] A placement plate 32 is installed above the shock-absorbing base 3. The storage tank 2 is placed on the upper surface of the placement plate 32. A cross bar 33 is fixedly installed inside the shock-absorbing base 3. The outer surfaces of both ends of the cross bar 33 are slidably sleeved with sliding sleeves 34. Rotating rods 35 are rotatably installed between the two sliding sleeves 34 and the bottom of the placement plate 32. The two rotating rods 35 are inclined, and the lower ends are away from each other, and the two rotating rods 35 are symmetrically arranged left and right. A shock-absorbing spring 36 is fixedly installed between the sliding sleeve 34 and the shock-absorbing base 3. The shock-absorbing spring 36 is sleeved on the outer surface of the cross bar 33; the shock-absorbing spring 36 is located on one side where the two sliding sleeves 34 are away from each other.

[0030] Through the above settings in this embodiment, when the refrigerated box body and the storage tank located inside the refrigerated box body are jolted and vibrated during transportation, the shock-absorbing spring plays a good shock-absorbing and buffering role in the vertical direction.

[0031] In this embodiment, L-shaped insertion plates 37 are fixedly installed on both sides of the bottom of the tank body protective sleeve 31, and connection blocks 38 are fixedly installed on both sides of the top of the bottom protective sleeve 30. The L-shaped insertion plates 37 are inserted into the inside of the connection blocks 38, and the L-shaped insertion plates 37 are fixedly connected to the connection blocks 38 through fixing bolts.

[0032] Through the above settings in this embodiment, the disassembly and assembly between the tank body protective sleeve and the bottom protective sleeve can be realized. Handles are fixedly installed on both sides of the top of the tank body protective sleeve, which is convenient for taking and placing the tank body protective sleeve.

[0033] In this embodiment, a shock-absorbing sleeve 39 is fixedly installed on the inner wall of the tank body protective sleeve 31.

[0034] By setting the shock-absorbing sleeve in this embodiment, the direct hard contact between the tank body protective sleeve and the storage tank is avoided, which is beneficial to protecting the storage tank.

[0035] In this embodiment, a ball 340 is rotatably installed on the inner wall of the sliding sleeve 34, and the ball 340 is in rolling contact with the outer wall of the cross bar 33;

[0036] By setting the ball in this embodiment, the friction between the sliding sleeve and the cross bar is reduced.

[0037] A chute 50 is formed inside the shock-absorbing base 3. A slider 51 is fixedly installed at the bottom of the sliding sleeve 50, and the slider 51 is slidably installed inside the chute 50.

[0038] With the above settings in this embodiment, while the sliding sleeve can move, it can be supported, reducing the vertical force exerted by the cross bar on the sliding sleeve.

[0039] Since the storage tank is placed inside the refrigerated box body and refrigerated by a refrigerator, the temperature inside the refrigerated box is maintained within a relatively low range. However, the existing refrigerated boxes have poor sealing performance, resulting in poor preservation effect of boron trichloride. To improve the sealing performance of the refrigerated box, the upper end of the refrigerated box body 1 is hermetically connected to the box cover. The box cover includes a cover main body 40, an air duct 41, and a gas charging and discharging channel 42; the air duct 40 surrounds the side wall of the cover main body 40, and the air duct 41 has a flexible outer seal that can expand or contract; the gas charging and discharging channel 42 is opened on the cover main body 40 in a switchable manner and extends to the air duct 41, so that the air duct 41 expands after inflation to tightly press against the side wall of the refrigerated box body 1 and contracts after deflation to separate from the side wall of the refrigerated box body 1.

[0040] With the above settings in this embodiment, it can be realized that the air duct is communicated with the gas charging and discharging channel. The air duct is inflated through the gas charging and discharging channel to expand and tightly press against the side wall of the refrigerated box body. The two are locked through the frictional force formed between the air duct and the side wall of the refrigerated box body, making the box cover and the refrigerated box body inseparable, and the air duct can play a sealing role. When it is necessary to open the box cover, only need to deflate the air duct through the gas charging and discharging channel to make it contract and separate from the side wall of the refrigerated box body, and the above-mentioned frictional force disappears, and the box cover can be easily opened.

[0041] It should be noted that for the intake process, the gas can be directly generated by an external gas generating device, and the gas charging and discharging channel can be cut off after inflation. The air duct needs to be at least partially made of a flexible material so that the air duct can expand when inflated and contract when deflated. For example, in some embodiments, the air duct can be made of plastic material, and in some other embodiments, the air duct can be made of resin material. In addition, when selecting the flexible material, the selected flexible material can also be selected to have the properties of high temperature resistance and low temperature resistance according to needs.

[0042] In this embodiment, a first groove with a C-shaped cross section is opened on the side wall of the cover main body 40, the flexible outer seal is annular and has a closed cross-sectional structure, and the flexible outer seal is embedded in the first groove.

[0043] The air duct in this embodiment can be completely composed of the flexible outer seal. During installation, only need to insert the annular flexible outer seal into the first groove. The C-shaped structure of the first groove can play a limiting role on the inflated flexible outer seal due to the necking design at the opening position. In this case, the air duct is fixed around the side wall of the cover main body, and the air duct is provided with an opening to communicate with the gas charging and discharging channel. Finally, the air duct is fixed on the cover main body.

[0044] In this embodiment, the cover body 40 is configured in a stepped shape, and the cover body 40 includes a connecting portion 400 extending into the refrigerating box body 1 and a lapping portion 401 abutting against the top surface of the refrigerating box body 1. The air duct 41 is provided on the connecting portion 400 to abut against or disengage from the inner wall of the refrigerating box body 1.

[0045] It should be noted that the size of the lapping portion is larger than the opening size of the refrigerating box body and does not protrude from the side wall of the refrigerating box body to limit the installation of the cover body. In this way, the surfaces of the overall outer contour of the refrigerating box body can be made flat.

[0046] In this embodiment, the gas charging and discharging channel 42 extends from the air duct 41 to the top surface of the cover body 40.

[0047] Through the above settings in this embodiment, it can be realized that when the box cover needs to be opened, the gas in the air duct can be discharged. When it is necessary to discharge the gas in the air duct to the outside of the refrigerating box, the outlet of the gas charging and discharging channel needs to be provided on the lapping portion, that is, the side surface or the top surface of the lapping portion. Setting the gas charging and discharging channel to extend to the top surface can reduce the opening difficulty, and only a through hole needs to be opened in the up and down direction.

[0048] In this embodiment, an end cover 43 is provided at the end of the gas charging and discharging channel 42, and a valve core is embedded in the end cover 43; the end cover 43 and the valve core do not protrude from the end surface of the cover body 40.

[0049] In this embodiment, a second groove is formed in the refrigerating box body 1 corresponding to the position of the air duct 41. The air duct 41 is configured to extend into the second groove and abut against the bottom of the second groove when expanding, and disengage from the second groove when contracting; at this time, the force blocking the separation of the refrigerating box body and the box cover body includes, in addition to the above-mentioned frictional force, the stop of the groove wall of the second groove against the air duct. The second groove can surround the side wall of the refrigerating box body. In addition, in some other embodiments, the second groove can be provided only on two adjacent or parallel side walls of the refrigerating box body, or the second groove can be provided on three adjacent side walls of the refrigerating box body. Through the above settings in this embodiment, the locking effect of the refrigerating box body can be improved, and the refrigerating box body and the box cover can be locked inseparably without a large internal pressure in the air duct. In order to enable the air duct to fully extend into the second groove and abut against the bottom of the second groove after expansion, here, the size and cross-sectional shape of the second groove are configured to match the air duct after inflation and expansion.

[0050] In this embodiment, the opening of the second groove is in arc transition with the side wall of the refrigerating box body 1.

[0051] Through the above settings in this embodiment, it can be realized to prevent the opening of the second groove from scratching the air duct.

[0052] Finally, it should be noted that the above only describes the specific embodiments of the present utility model in detail. However, the present utility model is not limited to the above-described specific embodiments. Equivalent modifications and substitutions made by those skilled in the art to the present utility model are also within the scope of the present utility model. Therefore, all equivalent transformations and modifications made without departing from the spirit and scope of the present utility model are covered within the scope of the present utility model.
