Description

Bivalve structure ore pulp pipeline sampler
Technical Field
The utility model relates to a novel ore pulp pipeline sampler of structure. In particular to an ore pulp pipeline sampler with a double-valve structure.
Background
In the gold ore dressing and cyaniding process, in order to timely and accurately detect the process indexes of each production link, a sampling point needs to be set in a key process link. In order to avoid human error caused by manual sampling, a sampling machine is usually used for sampling, and a pipeline type sampling machine is most commonly used.
Due to structural and performance limitations, existing pipeline-type sampling machines typically suffer from the following problems: firstly, the sampling time interval is fixed, and the time exceeding the maximum interval cannot be set; the valve switching time of each sampling is fixed, and the single sample collection amount is fixed; sampling under specific conditions cannot be realized, for example, sampling is required every time when the filter pressing equipment feeds, and sampling is not carried out when the filter pressing equipment does not feed. Secondly, the mechanical device of the sampler has a complex structure, and the electric control adopts a frequency converter and a three-phase motor, so that the opening and closing time and the opening degree of the valve cannot be accurately set; the maintenance is carried out each time, the vehicle is required to be stopped, and once a problem occurs, the problem cannot be timely treated.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problem that a bivalve structure ore pulp pipeline sampler is provided, realize the sampling operation under the specific condition to realize the maintenance of not stopping.
The technical scheme of the utility model as follows:
the utility model provides a bivalve structure ore pulp pipeline sampler, includes the ore pulp pipeline, its characterized in that: the sampling device also comprises a sampling box positioned below the ore pulp pipeline, and a sampling barrel is arranged in the sampling box; the bottom side of the ore pulp pipeline is connected with a sampling pipe, and a manual ball valve and an electric valve are installed on the sampling pipe; the lower end of the sampling tube is inserted into the sampling box and is positioned above the upper port of the sampling barrel.
Preferably, the electric valve is connected with a PLC controller; the PLC is used for receiving the switching signal of the electric valve and controlling the opening and closing of the electric valve through the intermediate relay; the PLC is also used for receiving the change-over switch signal and switching between a manual working mode and an automatic working mode.
Further preferably, the PLC controller employs a cpu 222; the electric valve adopts an on-off type valve with feedback.
The utility model has the following outstanding characteristics:
(1) the mechanical structure is simple and flexible, the original motor-driven lifting device is changed into an electric valve control, and the lifting device is small, exquisite, simple and convenient and easy to install;
(2) the control program is easy to develop, and a programmable controller Siemens 200PLC is adopted for control, so that sampling parameters can be set according to requirements;
(3) the control mode is easy to operate, and the touch screen control equipment is adopted, so that the sampling time and the sampling interval can be freely modified, and the sampling amount is controlled;
(4) the system has the functions of fault alarm and real-time display of the running condition, can remotely monitor the running condition of the sampler after networking, and can also remotely set sampling parameters;
(5) and the maintenance without stopping the vehicle can be realized. Due to the fact that the two-valve control structure is independent of each other, when the main pipeline normally conveys ore pulp, the electric valve for maintenance can be detached by cutting off the manual valve, maintenance flexibility is improved, and equipment operation rate is greatly improved.

Figure 2 is the electric control schematic diagram of the electric valve in the embodiment of the double-valve structure pulp pipeline sampler of the utility model.
Detailed Description
The invention is further described with reference to the following figures and examples.
As shown in fig. 1, the embodiment of the present invention includes an ore pulp pipeline 1 and a sampling box 5 located below the ore pulp pipeline 1, and a sampling bucket 7 is installed in the sampling box 5.
The sampling tube 2 of certain pipe diameter is welded in 1 bottom of ore pulp pipeline, installs manual ball valve 3 and motorised valve 4 on the sampling tube 2, and 2 lower extremes of sampling tube are gone into inside 5 sampling cases of probing and are located sampling bucket 7 upper end mouth top. The sample 6 is dropped from the sampling tube 2 into the sampling barrel 7.
Fig. 2 shows an electrical control circuit of the electric valve 4, the PLC of which employs a cpu222 of siemens 200 series, and the electric valve 4 employs an on-off type valve with feedback.
As shown in fig. 2, the electrical control circuit includes a power supply module, a controller, and an electrically operated valve. The power supply module is divided into a power frequency power supply and a control power supply, the power frequency power supply directly adopts an AC 220V power supply to supply power for the electric valve, and the control power supply outputs a DC 24V power supply to supply power for the controller after AC-DC conversion. The controller mainly comprises a PLC controller and has the following functions: receiving an electric valve opening and closing signal and controlling the opening and closing work of the electric valve through intermediate relays KA1 and KA 2; receiving a change-over switch signal and switching a manual/automatic working mode; and when the valve is abnormally opened or closed, a fault signal is output to the fault lamp. The electric valve is responsible for working according to the controller instruction, and feeds back switch running state information.
When the sampling device works, the PLC provides a switch action signal and action duration according to a set program, and controls the opening and closing action of the electric valve and the opening size, so that the functions of sampling at fixed time and controlling the sampling amount according to requirements are realized. The manual ball valve 3 is in an opening state during working, is in a closing state during maintenance and shutdown, and can realize the maintenance of the incoming material pipeline under the condition of not stopping the mine after being closed.
