The upper part of the Y-shaped groove is a V-shaped chute, and the lower part is an overflow groove of the adjustment plate. The two sides of the overflow groove of the adjustment plate are respectively symmetrically provided with positioning chute, where the positioning chute Locking grooves are arranged symmetrically below the grooves, and the locking plate is provided with a locking plate overflow groove corresponding to the adjustment plate overflow groove, and the two sides of the locking plate overflow groove are respectively provided with The positioning hole corresponding to the positioning chute is provided with a locking hole corresponding to the locking groove below the positioning hole, and the overflow groove of the adjustment plate overlaps with the overflow groove of the locking plate A complete overflow tank is formed, and the frame is connected with the slurry sampler through bolts.

The top of one side of the control board is provided with an upper positioning shaft, the bottom is provided with a lower positioning shaft, and the top of the other side of the control board is provided with an adjustment shaft, and the upper positioning shaft and the positioning slide The slot is connected with the positioning hole, the lower positioning shaft is connected with the shaft hole of the base, and the adjustment shaft is slidingly connected with the V-shaped sliding groove.

The set of control boards is two symmetrical control boards.

A wear-resistant layer is provided on the outer surface of the set of control boards.

The beneficial effect of the utility model is: after adopting the device, the size of the sampling port can be adjusted conveniently and quickly, so as to control the pulp flow rate of the pulp sampler. Since the outer surface of the control board is provided with a wear-resistant layer, the service life of the control board is prolonged and the cost is reduced. When the control board is worn out, the control board can be replaced quickly, which solves the problems of short service life, easy blockage and inconvenient replacement of the raw ore pulp valve. Moreover, only the control board needs to be replaced, and the pulp sampler does not need to be replaced as a whole, which saves expenses for the enterprise and creates economic benefits.

Detailed ways

The specific embodiment of the utility model is described below in conjunction with accompanying drawing.

As shown in Fig. 1 and Fig. 2, a flow control device of the utility model located at the inlet of the pulp sampler is characterized in that it includes a base 8 with shaft holes at both ends, and a frame 7 connected to the base 8 , the adjustment plate 1 connected to the upper part of the frame 7, the locking plate 5 abutted against the adjustment plate 1, a group of control boards connected to the base 8 at one end, and the other end of the control board It is respectively connected with the adjustment plate 1 and the locking plate 5, the adjustment plate 1 is provided with a Y-shaped groove, the upper part of the Y-shaped groove is a V-shaped chute 11, and the lower part is an adjustment plate overflow groove 12, Both sides of the overflow groove 12 of the adjustment plate are symmetrically provided with positioning chute 14 respectively, and locking grooves 17 are respectively symmetrically provided below the positioning chute 14, and the locking plate 5 is provided with The locking plate overflow groove 15 corresponding to the plate overflow groove 12, the two sides of the locking plate overflow groove 15 are respectively provided with the positioning holes 13 corresponding to the positioning chute 14, below the positioning hole 13 A locking hole 16 corresponding to the locking groove 17 is provided, the adjustment plate overflow groove 12 overlaps with the locking plate overflow groove 15 to form a complete overflow groove, and the frame 7 passes through The bolt 10 is connected with the slurry sampler.

The top of one side of the control board 6 is provided with an upper positioning shaft 3, and the bottom is provided with a lower positioning shaft 9, and the top of the other side of the control board 6 is provided with an adjustment shaft 4, and the upper positioning shaft 3 It is connected with the positioning chute 14 and the positioning hole 13, the lower positioning shaft 9 is connected with the shaft hole of the base 8, and the adjustment shaft 4 is connected with the V-shaped chute 11 Do sliding connections.

The set of control boards is two symmetrical control boards.

A wear-resistant layer is provided on the outer surface of the set of control boards.

The working principle of the flow control device located at the inlet of the pulp sampler of the present utility model is:

First, the lower positioning shafts 9 of one group of control boards are respectively inserted into the shaft holes of the base 8, and then the locking plate 5 is placed on the adjustment plate 1, so that the locking plate overflow groove 15, the positioning hole 13 and the locking plate 5 on the locking plate 5 The locking holes 16 are in one-to-one correspondence with the adjustment plate overflow groove 12, the positioning chute 14 and the locking groove 17 on the adjustment plate 1, and the upper positioning shaft 3 of this group of control boards is inserted into the positioning chute 14 and the positioning hole respectively. 13, the adjustment shafts 4 of this group of control boards are respectively inserted in the V-shaped chute 11, and the size of the sampling port is adjusted by pushing and pulling the adjustment shafts 4 at this time. When pushing upwards along the V-shaped chute 11, the sampling port expands. When pulling down along the V-shaped chute 11, the sampling port shrinks. After adjusting the size of the sampling port according to the production requirements, insert the bolt into the locking groove 17 and the locking hole 16, and lock it with a nut to complete the adjustment of the size of the sampling port. In this way, the flow rate at the inlet of the slurry sampler is controlled.
