The invention discloses a rubber powder ton package unloading auxiliary device, which comprises a hopper which is supported by foot stalls to be in position, an insertion rod and a support bracket, wherein the support bracket is erected on a feeding upper opening of the hopper; the insertion rod is vertically arranged on the support bracket and is located in the center of the feeding upper opening; a puncture head capable of puncturing a ton packaging bag is arranged on the top end of the inserting rod; a discharging lower opening of the hopper corresponds to the unloading position of the ton packaging bag; the puncture head is a conical body or a multi-pyramid body with the cone angle being less than or equal to 45 degrees; the height of the puncture head is ranged from 100mm to 200mm; the length of the insertion rod is ranged from 1000mm to 2000mm. According to the rubber powder ton package unloading auxiliary device, without consuming redundant manpower and energy cost, the problem that the rubber powder ton package is difficult to unload is solved, and the work efficiency is greatly improved.

The invention discloses a reciprocating bridge-breaking scraper apparatus used in a sludge bin. The scraper apparatus comprises: a cylindrical sludge bin for storing sludge. Two segments of semicircular horizontal tracks are disposed on a lower part of an inner wall of the sludge bin; two groups of conveyor belt contraction rollers are disposed on a position outside the sludge bin, the position having the height the same as that of the tracks outside the sludge bin, wherein each group of the conveyor belt contraction rollers includes two conveyor belt contraction rollers disposed on boundaries of the two segments of semicircular tracks respectively; a quadricuspid arc scraper matched with the tracks is disposed on each of the two segments of semicircular tracks; a conveyor-belt fixing shaft connected with conveyor belts and disposed on a base of the quadricuspid arc scrapers is in transmission connection with a corresponding group of the conveyor belt contraction rollers through a rotating shaft disposed on the wall of sludge bin; and an output shaft of a transmission motor is in transmission connection with each group of the conveyor belt contraction rollers. The scraper apparatus designed through the invention is characterized by a simple structure and easy operation and solves the problem of sludge bridge usually existing in the sludge bin with only low power.

The present invention provides a three-axis magnetic sensor and a preparation method thereof. In the preparation method of the three-axis magnetic sensor, after forming a Z-axis magnetoresistance structure, the Z-axis magnetoresistance structure is used as a mask to etch the The groove bottom of the first groove and the groove bottom of the second groove, to expose the groove bottom of the second groove, this step replaces the formation of the original photoresist after forming the Z-axis magnetoresistive structure , patterning the photoresist, etching the bottom of the second groove with the patterned photoresist as a mask, removing the photoresist, etc., which saves the patterned photoresist The required mask plate reduces the production cost, simplifies the process steps of forming the three-axis magnetic sensor, and also solves the problem of bridging the protective layer at the bottom of the first groove, thereby improving the yield rate.

The invention relates to a frequency modulation type self-oscillation jetting device and a use method thereof. The frequency modulation type self-oscillation jetting device comprises a shell with a tubular opening structure, a base plate, a vertical jetting inlet, a rectification cavity, a mixed flow cavity, a jetting outlet and tangent jetting inlets, wherein an opening in the bottom of the shell is fixedly connected with the base plate; the vertical jetting inlet is vertically arranged at the top of the shell; the inlet end of the vertical jetting inlet is connected with a backwashing pipeline; the outlet end of the vertical jetting inlet is communicated with the rectification cavity positioned at the upper part in the shell; a channel and the mixed flow cavity are arranged below the rectification cavity in sequence in the shell; the lower side of the rectification cavity is communicated with the inlet of the channel; the outlet of the channel is positioned above the inlet of the mixed flow cavity; the outlet of the mixed flow cavity penetrates through the base plate and is communicated with the jetting outlet; a jetting fusion region is formed between the channel outlet and the inlet of the mixed flow cavity; a plurality of tangent jetting inlets communicated with the upper part of the channel are formed in the outer side wall of the upper part of the shell at intervals. The frequency modulation type self-oscillation jetting device is energy-saving, so that the problems of local deformation, washout damage and the like to a filter screen due to extreme-high impact pressure are solved.

The invention discloses a multi-ventilation fixed bed biomass gasification furnace, which comprises a furnace body and a fire gate, wherein the fire gate is arranged in the middle part of the furnace body; the furnace body is provided with a forced air intake system which comprises an air feed mechanism, a ventilation device and a connecting pipe; the ventilation device is a ventilation pipeline which is positioned above the fire gate in the furnace body and is used for inletting air from a plurality of directions; and the air feed mechanism is positioned outside the furnace body and is connected with the ventilation pipeline through the connecting pipe which penetrates through the furnace wall so as to provide a forced air supply for the inside of the furnace. The multi-ventilation fixed bed biomass gasification furnace adopts a forced air feed mode that the air feed mechanism is combined with the ventilation device to feed air; and compared with the prior normal pressure air feed mode, the multi-ventilation fixed bed biomass gasification furnace improves the power of the gasification furnace, reduces the tar content in fuel gas, greatly reduces the tar content in waste water, and is advantageous for environmental protection; besides, the multi-ventilation fixed bed biomass gasification furnace does not have specific requirements on the dimension, the dryness, the feeding mode and the like of biomass raw materials, thereby widening the application range of the biomass raw materials.

The invention discloses an arch breaking device for preventing material bridging. The arch breaking device comprises a material storage cylinder, wherein the upper surface of the storage cylinder is fixedly provided with an upper cover through a first tightening hoop, a breathing device is fixedly arranged on the inner top wall of the upper cover, the lower surface of the storage cylinder is fixedly communicated with a connecting cylinder through a second tightening hoop. According to the arch breaking device for preventing material bridging, the arch breaking device is used for solving the problem of bridging of powder materials; when the butterfly valve or the flap valve is opened, the arch bridge is damaged by the arch breaking device installed in the hopper to enable the materials to flow out, the arch breaking device comprises a cross rod, an upper hanging ring is welded on the upper hanging ring, hooks are both arranged on the upper portion and the lower portion of the conical spring, the upper portion of the conical spring is hung on the upper hanging ring of the cross rod, the lower part of the disc plate is hung on the lower hanging ring on the disc plate, when the disc plate is opened, the disc plate drives the conical spring, the tension of the conical spring is used for destroying the arch bridge formed by the materials, so that the materials can flow out smoothly,and then have the characteristic that the powder in the hopper is subjected to arch breaking.
