Abstract
The utility model discloses a vacuum feeding machine with a metal detector. The vacuum feeding machine comprises a material cylinder which is installed on a rack, a vacuum generator is communicated with the top of the material cylinder, a feed pipe is arranged on the side surface of the material cylinder, a discharge port is arranged at the bottom of the material cylinder, the feed pipe is communicated with a material storage tank through a conveying pipeline, a metal coil is arranged on the periphery of an entry channel of the feed pipe, and the metal coil is electrically connected with a metal detection plate which is fixed on the material cylinder. The vacuum feeding machine with the metal detector has the advantages that the vacuum feeding machine has an alarm function for particles or powdery materials containing metals, thereby products are prevented from being polluted by the metals, and staff is timely alerted to replace damaged metallic screens.
Description
Technical field
The utility model relates to load transfer device, especially relates to a kind of vacuum feeder with metal detector.
Background technology
Vacuum feeder is a kind of load transfer device that transmits particle and powder material by means of pull of vacuum, is widely used in production and the scientific research field of pharmacy, food, chemical industry, pottery, feed, pigment, dyestuff, far products.The principle of vacuum feeder is: under compressed-air actuated driving, simultaneously discharging bottom valve cuts out, and also produces vacuum in powder material warehouse and the delivery duct, and under vacuum action, material sucks powder material warehouse from material storage jar through delivery duct and inlet point.When the suction powder reached specified operational throughput, vacuum generator was automatically out of service.The discharging bottom valve is opened, and the load transfer device internal pressure reaches balance, and material falls to the discharging position.The use vacuum feeder can greatly reduce the dust pollution in the workshop, improves cleanliness, and a large amount of the saving manually, and attenuating is polluted.But at preparation particle or granular material the time, need to use metallic screen; when sieving, can enter in the material owing to metallic screen metal filament after service failure; thereby can make material because wherein containing metal filament the user be produced bad effect; therefore in the present production technology usually after having produced certain hour the hand inspection metallic screen whether need to change; but can not choose exactly the only time, thereby thereby easily when metallic screen can also use, change to cause and waste or damaged the long period at metallic screen and just changed the pollution that causes material.
Summary of the invention
For problem set forth above, the utility model purpose is to provide a kind of material that can in time detect the vacuum feeder feed pipe whether to contain the vacuum feeder with metal detector of metallics.
The utility model is realized by following technical measures, a kind of vacuum feeder with metal detector, comprise rack-mounted material cylinder, the top of described material cylinder is communicated with vacuum generator, the side of described material cylinder is provided with a feed pipe, and the bottom of described material cylinder is discharging opening, and described feed pipe is communicated with a material storage jar by delivery duct, there are a wire coil, this wire coil to be electrically connected with a metal detection plate that is fixed on the material cylinder around the access road of described feed pipe.
Concrete, described metal detection plate comprises the high frequency generator that is electrically connected wire coil and the oscillating detector that is serially connected in successively the high frequency generator other end, audio frequency oscillator, power amplifier, loud speaker, and wherein high frequency generator, oscillating detector, audio frequency oscillator and power amplifier all are connected electrically on the power supply.
As a kind of optimal way, described vacuum generator is connected electrically on the metal detection plate.
As a kind of optimal way, be provided with material inlet valve on the described feed pipe, described discharging opening is provided with discharge valve.
The utility model is owing to being equipped with wire coil around feed pipe, this wire coil is connected electrically on the metal detection plate.When the particle that contains metal or granular material enter feed pipe by around when the feeding-passage of wire coil is installed; small variation occurs in the electric current that can cause wire coil; by amplifying circuit signal is amplified; and send alarm sound by loud speaker; thereby remind the staff that the metal in particle or the granular material is picked, and in time change metallic screen.
The utlity model has and to report to the police to the particle or the granular material that contain metal, can in time remind the staff to change the metallic screen of damage thereby can avoid product to be contaminated with metals also.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
A kind of vacuum feeder with metal detector, comprise the material cylinder 6 that is installed on the frame 8, the top of described material cylinder 6 is communicated with vacuum generator 5, the side of described material cylinder 6 is provided with a feed pipe 2 with the charging valve, the bottom of described material cylinder 6 is the discharging opening 7 with the discharging valve, described feed pipe 2 is communicated with a material storage jar 4 by delivery duct, has a wire coil 1, this wire coil 1 to be electrically connected with a metal detection plate 3 that is fixed on the material cylinder 6 around the access road of described feed pipe 2.Metal detection plate 3 comprises the high frequency generator that is electrically connected wire coil 1 and oscillating detector, audio frequency oscillator, power amplifier, the loud speaker that is serially connected in successively the high frequency generator other end, and wherein high frequency generator, oscillating detector, audio frequency oscillator and power amplifier all are connected electrically on the power supply.
More than be that the vacuum feeder of the utility model band metal detector is set forth; be used for helping to understand the utility model; but embodiment of the present utility model is not restricted to the described embodiments; anyly do not deviate from the change done under the utility model principle, modification, substitute, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
