The utility model discloses a water tank with constant pressure measurement function belongs to water tank technical field, aims at solving the most water outlet point of prior art is located water tank under one side of liquid level, and the position of water outlet point is fixed immovably, along with the water supply of carrying out, the liquid level in water supply water tank is constantly reduced, wherein the distance between water outlet point and liquid level will constantly reduce, lead to the water pressure of water outlet point constantly small, although the water tank usually has the water replenishing mechanism to reach the purpose of time water replenishing, but actually still can form fluctuation to the water pressure of water supply water tank, cannot realize constant pressure water supply, and the water replenishing of water tank single, every day also cannot carry out measurement statistics, thereby the actual water replenishing of subsequent management personnel cannot know water tank accurately, thereby bring the problem of influence to the judgment and overhaul of personnel. Including stainless steel water tank, the upper side of stainless steel water tank is connected with inlet pipe, and the other side below of stainless steel water tank is connected with outlet pipe.

The utility model belongs to the technical field of landscaping, in particular to a multilayer landscaping building, which is characterized in that the inner wall of a building body is fixedly connected with a connecting box, the top end of the connecting box is fixedly connected with a transmission motor, one end of the transmission motor is in transmission connection with a threaded rod, and the surface of the threaded rod is in threaded connection with a movable block; a sliding block is fixedly connected to the top end of the movable block, a breeding box is slidably connected to the surface of the sliding block, a sliding groove is formed in the bottom end of the breeding box, and a guide rod is slidably connected to one side of the breeding box. The transmission motor drives the threaded rod to rotate, the threaded rod rotates to drive the movable block to ascend and descend in the direction of the guide rod, when the movable block drives the breeding box to be lifted to the top end of the connecting box, the handle is pulled to drive the breeding box to break away from the surface of the movable block in the direction of the sliding block, and at the moment, the breeding box is separated from the building body; plants in the cultivation box can be rapidly replaced and cut, and the practicability of the device is guaranteed.

The invention discloses a preparation method of almond shell-based biomass hard carbon, which comprises the following steps: cleaning an almond shell material, drying, and crushing; pre-carbonizing the almond shell powder, so that the almond shell powder is preliminarily carbonized into carbon powder; further crushing, screening, pickling and drying the pre-carbonized carbon powder; and performing high-temperature carbonization on the pre-carbonized carbon powder, and dividing a heating curve into two sections during high-temperature carbonization to finally obtain the hard carbon material. Crushing and screening are carried out before pre-carbonization, the shape and size of a biomass precursor are controlled, the biomass cracking process of the material is more thorough, the defects of terminal hard carbon are reduced, a gap structure is increased, the capacity of the hard carbon material is increased, and the coulombic efficiency of the first round is improved. In the high-temperature carbonization stage, two different heating rates are adopted, the quick heating mode is adopted in the relative low-temperature stage, the preparation efficiency is guaranteed, the slow heating mode is adopted in the relative high-temperature stage, the performance of the material is improved, and especially the first-round coulombic efficiency index of the material is improved.
