Description

Flow control device installed at the inlet of the slurry sampler

technical field

The invention relates to the technical field of pulp sampling, in particular to a flow control device arranged at the inlet of a pulp sampler.

Background technique

In the mineral processing production process, the on-line index test of the pulp sample is a very important task, so the control of the amount and quality of the pulp sample at one time is particularly important. At present, the control of the sampling volume of the pulp is realized through the valve below the pulp sampler. Because the service life of the slurry valve is very short, and it is easy to block, it needs to be replaced frequently, resulting in an increase in cost. And it is very inconvenient to replace. At the same time, the inlet of the pulp sampler is a vulnerable part of the pulp sampler. After the inlet is damaged, the whole pulp sampler needs to be replaced, which causes great waste.

The purpose of the present invention is to provide a flow control device arranged at the inlet of the pulp sampler which can prolong the service life of the pulp sampler and is easy to replace.

The purpose of the present invention is achieved through the following technical solutions:

A flow control device provided at the inlet of the pulp sampler according to the present invention is characterized in that it includes a base with shaft holes at both ends, a frame connected with the base, an adjustment plate connected with the upper part of the frame, and The locking plate adjoining the adjusting plate, a set of control plates connected to the base at one end, and the other ends of the control plate are respectively connected with the adjusting plate and the locking plate, and the adjusting plate There is a Y-shaped groove on the top, 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. There are positioning chute symmetrically on both sides of the overflow groove of the adjustment plate. Locking grooves are respectively symmetrically arranged under the bottom of the locking plate, and the locking plate overflow grooves corresponding to the adjusting plate overflow grooves are arranged on the locking plate, and the two sides of the locking plate overflow grooves are respectively provided with The positioning hole corresponding to the positioning chute is provided with a locking hole corresponding to the locking groove under the positioning hole, and the overflow groove of the adjustment plate is overlapped with the overflow groove of the locking plate to form For a complete overflow tank, the frame is bolted to the slurry sampler.

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 effects of the present invention are: 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.

FIG. 2 is a top view of FIG. 1 .

Detailed ways

The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

As shown in Fig. 1 and Fig. 2, a kind of flow control device located at the inlet of the pulp sampler of the present invention 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 ends of the control board are 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 this adjustment plate overflow groove 12 are respectively symmetrically provided with positioning chute 14, and the below of this positioning chute 14 is respectively symmetrically provided with locking groove 17, and described locking plate 5 is provided with described adjusting plate The locking plate overflow groove 15 corresponding to the overflow groove 12 is respectively provided with a positioning hole 13 corresponding to the positioning chute 14 on both sides of the locking plate overflow groove 15, and the positioning hole 13 is provided below the positioning hole 13. There is a locking hole 16 corresponding to the locking groove 17, the adjustment plate overflow groove 12 overlaps with the locking plate overflow groove 15 to form a complete overflow groove, and the frame 7 is passed through the bolt 10 is connected with the pulp 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 operating principle of the flow control device located at the inlet of the pulp sampler of the present invention 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.

Since the outer surface of the control board 6 is provided with a wear-resistant layer, the wear resistance of the control board 6 is improved and its service life is prolonged. Simultaneously when the control board 6 wears and tear, the control board can be replaced to reach the purpose of prolonging the service life of the pulp sampler.
