The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.

In the description of the present invention, it is to be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships illustrated in the drawings, and are used merely for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, are not to be construed as limiting the present invention. Further, in the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

Fig. 1, 2 and 4 show a first embodiment of the utility model, and a dust removing device for a cement tank of a concrete mixing plant is characterized by comprising a conical cylinder 1, wherein a connector 2 for connecting an exhaust pipe of a cement tank 19 is arranged at the lower end of the conical cylinder 1, a gland 3 is detachably mounted at the upper end of the conical cylinder 1, a filter cartridge 4 detachably connected with the gland 3 is further arranged in the conical cylinder 1, an exhaust passage 5 is further arranged on the gland 3, and an inlet of the exhaust passage 5 is communicated with a cylinder cavity of the filter cartridge 4.

In specific implementation, a back-blowing nozzle 7 is installed at the center of the gland 3 through an installation opening 6, an outlet of the back-blowing nozzle 7 extends into a cylinder cavity of the filter cylinder 4, and an inlet of the back-blowing nozzle 7 is further connected with an air pump 8. During the back flushing operation, under the action of the air pump 8, air enters the filter cartridge 4 at a high flow rate, so that the filter cartridge 4 is rapidly expanded to cause primary impact vibration, and cement materials attached to the filter cartridge 4 are shaken off and fall into the cement tank 19 again through the exhaust pipe under the action of the cone 1. It should be noted that, the back-flushing operation is usually performed after the loading is finished and when the materials in the cement filling are relatively static, although the back-flushing operation inevitably causes disturbance to the gas in the cement tank 19, since the materials are in a relatively static state and the back-flushing time is short, the disturbance is very small and does not increase the dust content in the gas. Preferably, in order to ensure the back-blowing effect, a first accommodating groove 9 is formed in the circumference of the inner wall of the mounting opening 6, and a first sealing ring 10 for hermetically connecting the back-blowing nozzle 7 is accommodated in the first accommodating groove 9.

As can be seen from fig. 1 and 2, at least one section of the gland 3 extends downwards into the cavity of the exhaust pipe and serves as a boss 11 which is tightly matched with the wall of the cone 1. Preferably, in order to avoid the leakage of the dust-containing gas, a second receiving groove 12 is formed on the side wall of the boss 11, and a second sealing ring 13 for sealing and connecting the gland 3 is received in the second receiving groove 12.

In order to prevent rainwater from flowing into the filter cartridge 4, the outlet of the exhaust pipe is opened in the side wall of the gland 3.

Referring to fig. 3, in order to facilitate the installation and removal of the filter cartridge 4 by a worker, a clamping ring 14 is disposed at the upper end of the filter cartridge 4, and a clamping groove 15 matched with the clamping ring 14 is formed on the circumference of the lower end of the pressing cover 3.

As shown in FIG. 1, in order to facilitate workers to install a dust removing device on an exhaust pipe of a cement tank 19, a bracket 16 is arranged on the outer side wall of the cone 1, and the supporting height of the bracket 16 is adjustable.

Fig. 5 shows a second embodiment of the present invention, which is different from the first embodiment in that the present invention further includes a gas flow monitoring mechanism 17 and a reminder 18, which are arranged corresponding to each exhaust passage 5, wherein the gas flow monitoring mechanism 17 includes a flow sensor, an analog-to-digital converter connected to an output end of the flow sensor, and a microprocessor connected to an output end of the analog-to-digital converter, and an output end of the microprocessor is connected to a control circuit of the reminder 18.

When the gas flow in the exhaust passage 5 monitored by the flow sensor is lower than a preset threshold value, a reminder 18 may be triggered to remind a worker to perform maintenance or replacement on the filter cartridge 4.

In conclusion, the dust removal device only removes dust from naturally escaped dust, does not disturb the gas in the cement tank 19 during operation, and reduces the dust content in the gas; after the filter cartridge 4 is used for a period of time, the filter cartridge 4 can be subjected to back flushing under the action of the back flushing nozzle 7 and the air pump 8, so that dust on the filter cartridge 4 is shaken off and falls into the cement tank 19 again through the cone 1 and the exhaust pipe, the cleaning efficiency of the filter cartridge 4 can be ensured, and the material saving is facilitated; gland 3 and strain a section of thick bamboo 4 and be detachable, make things convenient for the staff to strain a section of thick bamboo 4 and maintain and change.

While the utility model has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model.
