Technical Field

[0001] This utility model relates to the technical field of denitrification catalyst production equipment, specifically to a production and batching system for a wide-temperature SCR denitrification catalyst. Background Technology

[0002] A Chinese utility model patent with application number 201520248072.8 discloses a production and batching system for SCR denitrification catalyst. It uses a conveying auger to feed auxiliary materials and a hoisting structure to feed the main raw materials. However, the control of the feeding is achieved by the conveying auger, which affects the accuracy of the feeding amount. On the other hand, feeding the main raw materials by hoisting them one bag at a time is also inconvenient. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing a production and batching system for a wide-temperature SCR denitrification catalyst that allows for precise and convenient feeding.

[0004] To achieve the above objectives, the present invention provides a production and batching system for a wide-temperature SCR denitrification catalyst, which adopts the following technical solution:

[0005] A wide-temperature SCR denitrification catalyst production and feeding system includes a frame, a feeding tank on the frame, a storage pipe below the outlet of the feeding tank, an inlet on the feeding tank, and an inclined feeding pipe at the inlet. The feeding pipe has at least three sets of on / off structures to form two sets of quantitative spaces. The feeding pipe has at least two sets, including an auxiliary feeding pipe and a main feeding pipe, and the main feeding pipe is connected to the main feeding structure.

[0006] A further improvement of the production and batching system for a wide-temperature SCR denitrification catalyst of this utility model is that the main feeding structure includes a vertically arranged feeding channel, a feeding chamber is provided at the upper side of the feeding channel, a fixed frame is arranged above the feeding channel, a sliding plate is slidably connected to the fixed frame, a lifting structure is provided below the sliding plate, a feeding hopper is connected to the lower end of the lifting structure, and a discharge port is provided at the lower end of the feeding hopper.

[0007] A further improvement of the production and batching system for a wide-temperature SCR denitrification catalyst of this utility model is that the bottom surface of the feeding chamber is inclined and the feeding chamber is connected to the main feed pipe.

[0008] A further improvement of the production and batching system for a wide-temperature SCR denitrification catalyst of this utility model is that the on / off structure is a clamping plate, which is slidably connected to the feed pipe.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This invention achieves precise control of the amount of material fed at one time by setting up a feeding pipe and an on / off structure, ensuring the accuracy of the raw material ratio; at the same time, the setting up of a feeding channel and a material placement cavity also reduces the frequency of feeding the main raw materials bag by bag, improving the convenience of operation.

[0013] 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.

[0014] like Figure 1 As shown, a wide-temperature SCR denitrification catalyst production and batching system includes a frame 1, a feeding tank 2 on the frame, a storage tank 10 below the outlet of the feeding tank, an inlet on the feeding tank, an inclined feeding pipe 3 at the inlet, and at least three sets of on / off structures 4 on the feeding pipe to form two sets of quantitative spaces. The feeding pipe has at least two sets, including an auxiliary feeding pipe and a main feeding pipe, with the main feeding pipe connected to the main feeding structure.

[0015] Specifically, the main feeding structure includes a vertically arranged feeding channel 5, a material placement chamber 9 at the upper side of the feeding channel, a notch at the lower part of the feeding channel with a door panel at the notch, a fixing frame 6 above the feeding channel, and a sliding plate 7 slidably connected to the fixing frame. The fixing frame is a single sheet material, preferably a C-shaped plate. A lifting structure 8 is located below the sliding plate, with a feeding bin connected to its lower end. The feeding bin has a discharge port at its lower end. Material is added to the feeding bin through the door panel and then moved upwards.

[0016] Furthermore, the bottom surface of the feeding chamber is inclined, and the feeding chamber is connected to the main feed pipe.

[0017] Preferably, the switching structure includes a clamping plate, which is slidably connected to the feed pipe. The sliding method can be controlled by a telescopic cylinder.

[0018] The working principle of this utility model is as follows: the main raw material is added into the feeding hopper, moved upward and then horizontally to the top of the feeding chamber, and then fed into the feeding wall and into the feeding pipe. It is blocked by the on-off structure, forming two sets of one-time feeding quantitative. Then, the material is fed into the feeding tank once, and the auxiliary material is also fed at the same time. They are mixed in the feeding tank and enter the storage tank. The storage tank contains a one-time proportioned material quantity, and then the wide-temperature SCR denitrification catalyst is produced.

[0019] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
