Problems solved by technology
[0007] In view of the above problems, the object of the present invention is to provide a sealed and adjustable groove rotary feed valve, which overcomes the problems caused by the narrow adjustment range of the feed volume of the traditional rotary feed valve, dirty powder falling, and serious wear between the valve core and the valve housing. Powder leakage, air return, and sundries can easily lead to problems such as jamming

Embodiment Construction
[0034] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. However, it should be understood that the accompanying drawings are provided only for better understanding of the present invention, and they should not be construed as limiting the present invention.
[0035] Such as figure 1 As shown, the present invention provides a sealed adjustable groove rotary feed valve, which includes:
[0036] A valve housing 1, forming a feed port 11 and a discharge port 12 communicating with the inner cavity of the valve housing 1;
[0037] The valve core 2 is rotatably arranged in the valve housing 1, and several grooves 21 are evenly arranged on the outside of the valve core 2 and along its circumferential direction,
[0038] Filling block 3 , a filling block 3 is detachably arranged in each groove 21 , and is used to change the effective delivery volume formed by several grooves 21 outside the valve core 2 .

The invention discloses a sealing type adjustable groove rotary feeding valve, which is characterized in that: it comprises a valve housing, on which a material inlet and a material outlet communicating with the inner cavity are formed; In the valve casing, several grooves are evenly arranged outside the valve core and along the circumferential direction of the valve core; a filling block is detachably arranged in each of the grooves, and a filling block is detachably arranged, It is used to change the effective delivery volume formed by several grooves on the outside of the valve core. According to the invention, the feeding amount of the rotary feeding valve can be adjusted not only by the rotating speed of the rotary valve, but also by changing the effective delivery volume formed by several grooves on the outside of the valve core, thereby greatly improving the feeding capacity of the rotary feeding valve. The volume adjustment range, the rotary feeding valve can not only be used in the occasions where the feeding volume varies widely, but also can work stably when the feeding volume is relatively low.
Description
technical field [0001] The invention relates to a sealed and adjustable groove rotary feeding valve, which belongs to the field of powder conveying, in particular to the field of powder quantitative conveying. Background technique [0002] Rotary feed valve is a common powder conveying equipment, which is widely used in energy, chemical, building materials and other industries. In the long-term actual operation, the traditional rotary feed valve exposed 4 significant problems: [0003] (1) The adjustment range of feeding amount is narrow. The feeding amount of the rotary feed valve is determined by the total volume of the feed valve groove and the rotary valve speed. The total volume of the groove of the traditional rotary feeding valve is fixed, and the feeding amount is only determined by the rotational speed. However, when the frequency converter that controls the speed of the feed valve operates in the low-frequency region, it is difficult to start or the motor vibrat...
