Description

Technical Field

[0001] The utility model relates to the technical field of nail shooting, in particular to an anti-recoil explosive shooting nail. Background Art

[0002] A clarifying tank is a water purification device that uses gravity to separate suspended matter and flocculants in water. Sedimentation tanks are categorized as horizontal or vertical based on the direction of water flow. Sedimentation efficiency is determined by the flow rate and residence time of the water in the tank. To improve sedimentation efficiency and reduce land use, honeycomb inclined tube countercurrent flow sedimentation tanks, accelerated clarifiers, and pulse clarifiers are commonly used. Sedimentation tanks are widely used in wastewater treatment.

[0003] Wastewater treatment in the papermaking industry should focus on improving the recycling rate, reducing water consumption and wastewater discharge, and at the same time actively exploring various reliable, economical and fully-utilizing treatment methods for useful resources in wastewater. For example, coagulation sedimentation or flotation can remove suspended solids in wastewater; chemical precipitation can decolorize; biological treatment can remove BOD, which is more effective for kraft paper wastewater; wet oxidation is more successful in treating sulfite pulp wastewater, but when the sedimentation tank is in use, a water receiving trough needs to be installed on the top of the sedimentation tank. The water receiving trough is generally fixed with nails. As the fixed water receiving trough grows in use, the nails will become loose, causing the water receiving trough to fall, affecting the use of the sedimentation tank.

[0004] In view of the problem that as the water receiving trough is used for a long time, the nails used to fix the water receiving trough become loose and thus cause the water receiving trough to fall, there is an urgent need for an anti-recoil explosive nail. Summary of the Invention

[0005] Aiming at the problem that the nails used to fix the water trough become loose as the water trough is used for a longer time, thereby causing the water trough to fall, the utility model proposes an anti-recoil explosive nail to solve the above problem.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is a kind of anti-recoil explosive nail, including a column and a striking head, one end of the column is fixedly connected to the striking head, an explosive head is installed on the striking head, a gasket is provided on the end of the column away from the striking head, a through hole is provided on the gasket, and the striking head can abut against the gasket after the column passes through the through hole of the gasket, and at least two rows of barbs are evenly arranged along the circumference of the outer cylindrical surface of the column. When in use, the explosive head provides power for the nail, so that the nail is pushed into the wall to connect the water tank for fixation, and at the same time, the barb is used to block the retreat of the nail to avoid the situation that the nail becomes loose and falls, thereby ensuring the fixing effect of the water tank and having a good overall use effect.

[0007] Furthermore, the side of the gasket that contacts the wall is flat, and the side that contacts the striking head is arc-shaped.

[0008] Furthermore, the end of the barb away from the column body is inclined toward the direction close to the explosive head.

[0009] Furthermore, each row of barbs includes at least two barbs that are evenly spaced along the length direction of the column.

[0010] Furthermore, the barbs are made of metal.

[0011] Furthermore, the gasket adopts a 5mm thick galvanized gasket.

[0012] The beneficial effects of the utility model are:

[0013] The nail is provided with barbs on the column, which can block the nail when it retreats, avoiding the nail from falling, ensuring the fixing effect of the nail to the water tank, and improving the overall use effect. BRIEF DESCRIPTION OF THE DRAWINGS
