Problems solved by technology

Port bulk cargo sampling is the basis of inspection and quarantine work, but judging from the current actual situation of port bulk cargo sampling operations, many port berths do not have the installation conditions for fixed sampling facilities, making it difficult to take samples, or can only be done manually The sampling method in the storage yard results in the lack of representativeness of the sampled samples, which is easy to cause quality disputes, and also brings safety hazards, high labor intensity, and poor working environment to the on-site staff.

Embodiment 1

[0027] Such as figure 1 , figure 2 As shown, a mobile sampling device suitable for port bulk cargo sample sampling of the present invention includes a mobile platform 1 and a feeding belt conveyor 4 installed on the mobile platform 1, a waste belt conveyor 5, and a lifting and loading device 3 , a large hopper 2, a sample collector 6, a control unit 7 is also set on the mobile platform 1, and the control unit 7 includes a PLC, a monitoring computer CGP and auxiliary equipment. It also preferably includes a shield 8, the shield 8 is detachably installed on the mobile platform 1, the feeding belt conveyor 4, the discarding belt conveyor 5, the lifting feeding device 3, the large hopper 2, the sample collector 6 is installed in the shield 8.

[0028] Wherein: the mobile platform 1 includes a bottom plate and universal wheels installed on the bottom of the bottom plate; the feeding belt conveyor 4, the discarding belt conveyor 5, the lifting feeding device 3, the large hopper 2...

Embodiment 2

[0031] A mobile sampling device suitable for sampling bulk cargo samples of the present invention needs to be aimed at different samples and different time requirements, and the conveying speed of the belt conveyor can be changed to achieve the best sampling effect.

[0032] According to the relevant ISO standards, the number of samples of different batches of iron ore is as follows

[0033]

[0034] According to GB / 10322.12000 sampling mass m formula

[0035] m=ql / 3.6v

[0036] q-----The flow rate of ore on the belt conveyor, t / h

[0037] l-----Sampling machine interception mouth opening, m (should be at least 3 times the maximum particle size of the ore)

[0038] v-----Sampling machine interception speed, m / s (should not be greater than 0.6m / s, unless the opening of the interception port increases accordingly)

[0039] A forklift or other equipment that can be additionally configured sends the materials that need to be sampled into the small hopper in the lifting and f...

Abstract

The invention provides movable sampling equipment applicable to sampling of port bulk cargo samples. The equipment comprises a moving platform (1), a feeding belt conveyor (4), a material discarding belt conveyor (5), a lifting and feeding device (3), a large hopper (2) and a sample collector (6), wherein the feeding belt conveyor (4), the material discarding belt conveyor (5), the lifting and feeding device (3), the large hopper (2) and the sample collector (6) are mounted on the moving platform (1), and the moving platform (1) comprises a base plate and universal wheels mounted below the base plate; the large hopper (2) and the lifting and feeding device (3) are sequentially arranged above the feeding belt conveyor (4); the sample collector (6) is mounted at the head position of the feeding belt conveyor (4). The movable sampling equipment is wholly mounted on the moving platform, other towing vehicles are utilized, the equipment can travel freely on the field, and the defect that a fixed sampling facility is inconvenient to mount is overcome. A protective housing is designed to be arranged on a moving vehicle, the totally-enclosed form is adopted, sample contamination caused by external dust is avoided, equipment stains are reduced, the housing is provided with a safety access door and an observation hole, and the running condition of the equipment can be detected at any moment.

Description

technical field [0001] The invention relates to the technical field of port bulk cargo sampling. Specifically, the invention designs a mobile sampling device suitable for port bulk cargo sample sampling based on the characteristics of port bulk cargo samples. Background technique [0002] Port operation is an intersecting and intricate large system composed of human, machine, cargo, ship, environment and other elements. Port bulk cargo sampling is the basis of inspection and quarantine work, but judging from the current actual situation of port bulk cargo sampling operations, many port berths do not have the installation conditions for fixed sampling facilities, making it difficult to take samples, or can only be done manually The sampling method in the storage yard leads to the lack of representativeness of the sampled samples, which is easy to cause quality disputes, and also brings safety hazards, high labor intensity, and poor working environment to the on-site staff. ...
