Description

Technical Field

[0001] The utility model relates to a containing device, in particular to a desiccant containing device for a Roots blower. Background Art

[0002] A Roots blower is a positive displacement blower that compresses and transports gas by means of the relative movement of two lobe-shaped rotors within a cylinder.

[0003] When a Roots blower transports special gases such as oxygen and nitrogen, before the blower operates, the inside of its casing needs to be kept sufficiently dry to ultimately achieve stable gas transmission.

[0004] Currently, the drying treatment method for the inside of the blower casing is to directly place several desiccant packets inside the casing for drying treatment. However, although this method can achieve the purpose of maintaining continuous dryness inside the casing, before the blower operates, all the desiccant packets need to be taken out, and the operation efficiency is slow. Moreover, in actual operation, it is found that operators often forget to take out or miss taking out desiccant packets and directly start the blower, resulting in desiccants remaining inside the blower, causing varying degrees of damage to the blower and reducing the service life of the blower. Summary of the Utility Model

[0005] In view of the above technical problems, the utility model provides a desiccant containing device for a Roots blower. A plurality of desiccant packets are placed inside the desiccant containing device for the Roots blower.

The locking hook 4 and the rear cover plate 2 are elastically connected through the torsion spring 5.

[0044] A locking groove 102 is provided on the outer circumference of the cylinder body 1 near the rear end. After the rear cover plate 2 is closely attached to the cylinder body 1, the locking hook claw 402 on the locking hook 4 is located in the locking groove 102 to realize the locking and fixing between the rear cover plate 2 and the cylinder body 1.

[0045] While ensuring the firmness of the fixation between the rear cover plate 2 and the cylinder body 1, it is possible to achieve the rapid disassembly and assembly of the rear cover plate 2, which facilitates the addition or replacement of desiccants, as well as the cleaning or maintenance of the accommodation cavity 6.

[0046] The number of locking hooks 4 is four, and the four locking hooks 4 are evenly distributed along the outer circumference of the rear cover plate 2. Four locking grooves 102 corresponding to the locking hooks 4 are provided on the outer circumference of the cylinder body 1 near the rear end.

[0047] After the rear cover plate 2 is installed, it can achieve uniform force in the circumferential direction of the rear cover plate 2, ensure the firmness of the fixation between the rear cover plate 2 and the cylinder body 1, and avoid the situation of the rear cover plate 2 being deformed due to force extrusion. The service life of the entire accommodation device is increased.

[0048] The shapes of the plurality of fixing holes 302 are elongated, and the plurality of elongated fixing holes 302 are evenly distributed along the position near the outer circumference of the flange plate 3. During installation, when the positions of the installation holes on the flange plates at the air inlet and outlet of the blower are irregular, the installation position can be adjusted through the elongated fixing holes 302 to achieve rapid installation and fixation, increasing the application range of the accommodation device.

[0049] Only the above-mentioned are specific embodiments of the present invention, and the scope of implementation of the present invention cannot be limited thereby.
