Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of ball mill, concretely relates to a transmission structure for integrated pilot ball mill. BACKGROUND

[0002] Pilot is a term in industry, and is a state between laboratory small test and industrial production. After a product is successfully developed in a laboratory, industrial production is needed, the cost of industrial production is too high and has great risk, and equipment has amplification effect in amplification process, therefore, pilot is needed to verify, gradually amplifies, observes effect, and whether industrial production can be carried out, so as to reduce risk, the transmission mode of the existing pilot ball mill is belt transmission: the motor is connected with the driving pulley through a key and a taper sleeve, the driving pulley drives the driven pulley to rotate through a belt, due to the limitation of transmission ratio, the size of the driven pulley is particularly large, in the process of equipment integration, the installation space of other equipment participating in integration is limited due to the size of the driven pulley. CONTENT OF THE UTILITY MODEL

[0003] In order to overcome the above-mentioned technical problems existing in the prior art field, the purpose of the utility model is to provide a transmission structure for integrated pilot ball mill, the installation space required for transmission is greatly reduced, the available space for installation of other equipment is obviously improved, and the overall appearance of the equipment is more compact and beautiful.

[0004] The utility model provides a transmission structure for integrated pilot ball mill, is installed on the rack on the top of pilot ball mill, including motor and speed reducer, motor and speed reducer fixed connection, the motor is connected with the electric control cabinet through the wire, the output shaft of motor is connected with the shaft coupling of speed reducer through the key, the speed reducer is fixed on the rack, and is connected with the main coupling of pilot ball mill, the main coupling is connected with the grinding main shaft of pilot ball mill.

[0005] The shell of the motor and the shell of the speed reducer are fixedly connected through bolts, elastic pads and flat pads.

[0006] The speed reducer is fixed on the rack through bolts, elastic pads, flat pads and nuts.

[0007] The main coupling of the pilot ball mill is provided with a taper sleeve, and the speed reducer is connected with the main coupling through the taper sleeve.

[0008] The utility model provides a transmission structure for integrated pilot ball mill, its beneficial effect lies in, the belt drive of replacing existing pilot ball mill, the transmission mode of pilot ball mill is changed, so that the equipment transmission required installation space greatly reduces, and other equipment installation available space is obviously improved, and the whole appearance of equipment is more compact and beautiful, and the whole transmission structure becomes relatively simple in the equipment installation process, and the problem of other equipment installation space being limited because the driven pulley size is big is solved, the external rotating part of equipment is reduced, and the whole safety of equipment is improved.

[0013] Below, combining an embodiment, the transmission structure for integrated pilot ball mill provided by the utility model is explained in detail with reference to the drawings.

[0014] EMBODIMENT

[0015] Refer to Figure 1 The transmission structure for integrated pilot ball mill of this embodiment is installed on the rack 7 on the top of pilot ball mill, and includes motor 1 and speed reducer 5, the motor 1 and speed reducer 5 are fixedly connected, the motor 1 is connected to the electric control cabinet through electric wire, the output shaft of motor 1 is connected to the coupling 3 of speed reducer through key, the speed reducer 5 is fixed on the rack 7 and is connected to the main machine coupling 4 of pilot ball mill, and the main machine coupling 4 is connected to the grinding spindle 6 of pilot ball mill.

[0016] The speed reducer 5 is provided with a silk hole, and the shell of motor 1 and the shell of speed reducer 5 are fixedly connected through bolt 2, elastic pad, flat pad and silk hole.

[0017] The speed reducer 5 is fixed on the rack 7 through bolt, elastic pad, flat pad and nut.

[0018] The main machine coupling 4 of pilot ball mill is provided with a taper sleeve, and the speed reducer 5 is connected to the main machine coupling 4 through the taper sleeve.

[0019] The screw, the elastic washer, the flat washer, the nut and the bolt are standard parts, and the embodiment will not be described again.

[0020] Before the device works, the motor 1 is connected to the electric cabinet through the electric wire, then the electric cabinet is powered on, the PLC controller of the electric cabinet controls the start of the motor 1, the rotating speed of the motor 1 will be reduced according to the speed ratio under the action of the speed reducer 5, so that the output shaft speed of the speed reducer 5 reaches the rated rotating speed required by the pilot ball mill, and is transmitted to the main shaft coupling, the device grinding main shaft is driven to rotate through the main shaft coupling, the grinding of the material by the device is completed, and after the grinding is completed, the motor is stopped rotating through the PLC controller of the electric cabinet.
